RiB Newsletter #14 – Are We Smart (Contract) Yet?

We’re seeing a bunch of interesting Rust blockchain and crypto projects, so this month the “Interesting Things” section is loaded up with news, papers, and project links.
This month, Elrond, appeared on our radar with the launch of their mainnet. Although not written in Rust, it runs Rust smart contracts on its Arwen WASM VM, which itself is based on the Rust Wasmer VM. Along with NEAR, Nervos, and Enigma (and probably others), this continues an encouraging trend of blockchains enabling smart contracts in Rust. See the “Interesting Things” section for examples of Elrond’s Rust contracts.
Rust continues to be popular for research into zero-knowledge proofs, with Microsoft releasing Spartan, a zk-SNARK system without trusted setup.
In RiB news, we published a late one-year anniversary blog post. It has some reflection on the changes to, and growth of, RiB over the last year.
The Awesome Blockchain Rust project, which is maintained by Sun under the rust-in-blockchain GitHub org, has received a stream of updates recently, and is now published as the Awesome-RiB page on rustinblockchain.org.
It’s a pretty good resource for finding blockchain-related Rust projects, with links to many of the more prominent and mature projects noted in the RiB newsletter. It could use more eyes on it though.

Project Spotlight

Each month we like to shine a light on a notable Rust blockchain project. This month that project is…
ethers.rs
ethers.rs is an Ethereum & Celo library and wallet implementation, implemented as a port of the ethers.js library to Rust.
Ethereum client programming is usually done in JavaScript with either web3.js or ethers.js, with ethers.js being the newer of the two. These clients communicate to an Ethereum node, typically via JSON-RPC (or, when in the browser, via an “injected” client provider that follows EIP-1193, like MetaMask).
ethers.rs then provides a strongly-typed alternative for writing software that interacts with the Ethereum network.
As of now it is only suited for non-browser use cases, but if you prefer hacking in Rust to JavaScript, as some of us surely do, it is worth looking into for your next Ethereum project.
The author of ethers.rs, Georgios Konstantopoulos, accepts donations to sponsor their work.
Note that there is also a Rust alternative to web3.js, rust-web3.

[Call to Action] Make your political contributions in Bitcoin (HowTo)

As the political season heats up I've patiently waited for politicians to install BTCPay servers to allow bitcoin contributions. I'm now realizing that the wait will likely take forever. Then I realized I didn't need to wait. I can send anyone bitcoin anytime I want using an expiring paperwallet. It's all totally legit. Works like this:
  1. Any "gift" to a campaign is an "in-kind" contribution.
  2. Disclosure of personal information is only required for contributions above $200.
  3. Paper wallets can easily be mailed to the campaign headquarters just like checks.
  4. You should keep the private keys and revoke the funds after 90 days (or whatever).
  5. The more paper wallets they receive, the more likely they are to favor bitcoin.
Be aware, your contribution will likely just get stolen by a volunteer, so don't go overboard.
If everyone on this subreddit who plans (or can) vote in the upcoming elections were to give 11,000 SAT to the candidate of their choice, eventually they would have enough to warrant getting an exchange account KYC'ing and going through all the same pains we go through to comply with US AML/KYC law. Possibly provide them a way to walk a mile in our shoes. It will also show these candidates that bitcoin can be used "for good" and isn't just for drug runners.
Although you don't need to fill out a disclosure for small ( < $200 ) contributions, it is still probably a good idea to do so. What you should disclose is Name, Address, Employer, and Occupation. You will also need to sign a statement attesting that you are not contributing on behalf of a labor union, federal contractor, or foreign national (unless a lawful US resident).
As warned above, care should be taken in how much you put on the wallet. It's just like cash, so any volunteer opening mail could swipe it. You also need to be careful to only use a trusted wallet. The bitaddress.org is broadly trusted and a good default choice. I ported it to python in the pypaperwallet module, but most people will likely stick with bitaddress.org as it has had years to build trust and reputation. Obviously you should download the zip and run it locally so as not to trust a web server with private keys.

Basic bitaddress.org HowTo:

  1. Download zip from https://github.com/pointbiz/bitaddress.org/tree/v3.3.0
  2. Download PGP key from https://www.bitaddress.org/ninja_bitaddress.org.txt
  3. Import Ninja's expired key that you downloaded in [2] into GPG.
  4. Verify Ninja's key fingerprint matches the fingerprint in his BitcoinTalk post
  5. Unzip the zip downloaded in [1] and enter that directory
  6. Verify the file bitaddress.org.html.sig using Ninja's expired key
  7. Open the bitaddress.org.html file in Chrome
  8. Print the paper wallet and fund it with a few dollars worth of BTC
  9. Include a letter attesting that you aren't a foreign influencer, with a union, or contractor
  10. Include your Name, Address, Employer and Occupation in the letter and sign it
  11. Make a copy of the wallets private key to void the wallet after 90 days
  12. Mail the wallet and signed letter to the campaign of your choosing
  13. If the funds haven't moved after 90 days, sweep them back to yourself
I've produced the form letters in pypaperwallet, but as I said, it's a new repo from some random redditor. In any case, here's the howto for my module:

Basic pypaperwallet HowTo:

  1. Find latest release at https://github.com/brianddk/pypaperwallet/releases
  2. Expand "Assets" and download the "Source code (tar.gz)" as pypaperwallet.tar.gz.
  3. Download the *.tar.gz.sig file naming it pypaperwallet.tar.gz.sig
  4. Download my key from https://brianddk.github.io/darkweb/brianddk/pub.asc
  5. Import my key using gpg --import pub.asc or whatever you named it.
  6. Verify download with gpg --verify pypaperwallet.tar.gz.sig
  7. Extract the contents of the .zip or .tar.gz file to any directory
  8. From Python 3.7 run pip install pypaperwallet.tar.gz to install dependencies
  9. Review the README.md on how to install the GTK cairo dependency
  10. Modify test.py to your liking and run from python 3.7 to produce the PDFs.
  11. To change wording, modify the contents of template.py
Disclaimer: This mainly pertains to US campaign law, but other countries likely have similar ways for voters to contribute.

The History, The Current State And The Future Of NavCoin

The History, The Current State And The Future Of NavCoin

This is it. If you're interested to see what NAV is all about, this is the ultimate guide for you. You will learn about the history of NavCoin and how it evolved. You will learn about the current state and features of NavCoin and you will learn about the exciting new features that are planned and coming up in the (near) future.
So buckle up, this is going to be a long ride!

Table Of Content


Introduction - What is NavCoin?


The History

Introduction
The following chapter will summarize and break down the history of NavCoin in a few sentences. NAV started a long time ago, went through rebrandings and changes of the core team before it became what it is today.

SummerCoin
NavCoin was initially first introduced under the name SummerCoin on April 23 in 2014. SummerCoin was a fork of the Bitcoin blockchain. It used to have a PoW/PoS hybrid algorithm with a block time of 45 seconds.

SummerCoinV2 /NavajoCoin
Soon after the initial launch of SummerCoin, the original developer left and SoopY (soopy452000 on bitcointalk) took over as the main developer and rebranded the project to SummerCoinV2 respectively NavajoCoin and introduced new features.
The name NavajoCoin was chosen in honor of the Navajo Code Talker. The unbreakable Navajo code was used to encrypt highly classified military information and commands and decrypt the same in WW II.
SoopY introduced a technology which allowed sending transactions anonymously and private. This technology was called "Navajo Anonymous Technology". SoopY also released a new wallet and set the Proof of Stake rewards at 10% for the first year, 5% for the second year and 2% for every year after.

NavCoin
On August 12, 2014, Craig (current lead core developer, pakage on bitcointalk) started to get involved with NAV by helping to set up a website [10].
It was officially announced that Craig joined the core team as a "Wallet & Web Developer" on November 06, 2014.
The last tokenswap and restart of the blockchain of NAV happened on May 12, 2016.
Soon later, SoopY stopped showing up and Craig stepped into the role of the lead core developer. Since then, Craig has assembled a strong team with which he built NavCoin into what it is today.
Currently, Craig and the NavCoin Core team is located in New Zealand and they are actively developing many ground-braking features which differentiate NAV from other cryptocurrencies. You will read more about that later in this article.

The Current State

Introduction
The year 2018 has been a thriving year for the NavCoin ecosystem. Despite the USD price of NAV not reflecting it, in 2018 the core team has developed a whole bunch of new features. Also the core content creators published the first official guidelines that function as an orientation guide for community content creators. This chapter will give you an overview of the current team, the features, the prior mentioned guidelines and the community of NavCoin.

Core Team [1]
Last year, the core team has grown alot. It contains of developers, content creators and interns. The core team are employees of Encrypt S, the New Zealand's leading blockchain R&D lab. Encrypt S is developing blockchain solutions since 2014 and values building open-source software highly.

Craig MacGregor - Chief Executive Officer
Craig is the CEO of Encrypt S and the founder of NavCoin. He is one of the world's most experienced blockchain developers. Craig founded NavCoin in 2014 and is developing software for it since then. He has assembled a strong team of like-minded people. Craig also speaks at seminars and conferenced. Some of the companies and conferences he did blockchain education sessions at are Oracle, Xero, Air New Zealand, Blok Tex and trademe. Together with the team, he is also doing a education series on YouTube where he explains upcoming features in-depth for the community.

Alex Vazquez - Chief Technical Officer
Alex is the CTO of Encrypt S and the most active contributor to the NavCoin core Github. He has incredible knowledge of blockchains and proposes and implements solutions for challenges and features. He supports community developers frequently and answers any questions of the community thoroughly. Like Craig, Alex is developing software for the NavCoin ecosystem for a very long time. Alex speaks at universities at times and educates students about the blockchain technology.

Paul Sanderson - Lead Software Engineer
Paul is the Lead Software Engineer at Encrypt S. He has a flair for technology. His technical and management skills are perfectly suited for consultancy and investment advising. He also frequently contributes to the NavCoin core source code.

Rowan Savage - Senior Software Engineer
Rowan is a full stack software engineer with more than a decade experience in developing complex front-end web applications. He joined Encrypt S in February 2018 and has since been involved in the Valence Plattform, the Kauri Wallet and NavCoin Core. You will read more about these feature/projects later.

Carter Xiao - Lead UX/UI Designer
Carter specializes in user-centric design and is also very talented with 3D animation, motion graphics and programming. One of NavCoins core principle is "Simplifying Crypto" and UX/UI is a very important part of that.

Matt Paul - Software Engineer
Like Rowan, Matt is a full stack Software Engineer. He joined the core team in Mai 2017 and has since worked on NavPay, NavPi, the Kauri Wallet and NavCoin Core. Kieren Hyland - Chief Strategy Officer Kieren is one of the employees that are working for Encrypt S for a very long time. He is the CSO and is a digital strategist and growth hacker with a passion for new technology and has a lot of experience in online marketing. Laura Harris - Creative Director Laura has a combination of commercial and creative flair. She manages the social media accounts for NavCoin and ensures, that NavCoins' message is always powerful, relevant and distinctive. John Darby - Content Creator John is an internationally awarded Technology and Financial sector marketing communications specialist. He is one of the Core Content Creators for NavCoin.

Features of NavCoin [2]
The following features are currently available and have been developed in the last months and years. It is sorted from newest to oldest.

Static Block Reward
The soft-fork for the enabling of static block rewards have been accepted and became active recently at 5th January 2019. This means, that the block reward was changed from a percentage based reward to a static reward. This will incentivize the stakers to have their node online 24/7 which increased the security of the network. It also aligns NavCoin with the PoSv3 specification. With this implementation, the yearly inflation will be 3.6% currently and will exponentionally decrease because of the static value of the rewards. Every staked block will now give the staker 2 NAV. Depending on how many people are staking, the yearly percentage varies. With the network weight currently being around 20'000'000 NAV, stakers earn around 10% rewards from staking 24/7.

Cold staking
To provide extra security to participants in the staking process in the NavCoin network, the core team decided to implement cold staking. This allows to store NAV offline and still be able to sign staking inputs. Looking forward, a possible integration into the Ledger Nano S would mean, that one can stake NAV securely from a offline hardware wallet. How cool is that?

OpenAlias
One of the core principle of NAV is to simplify cryptocurrencies. Many non-technical people are deterred from the long, cryptic addresses used in wallets. When sending funds, you have to make sure that every single letter and digit is correct which is nerve-wracking for the average person. NavCoin has implemented OpenAlias, which allows to transform the wallet address into a email-like form. Everyone can register a name like "[[email protected]](mailto:[email protected])". Funds can then be sent to this name, which makes sending crypto much easier and less error-prone.

Community Fund
This is the one big feature I was most excited about. NavCoin core has implemented the first fully decentralized community fund. Acceptance of proposals and release of funds is all approved by the decentralized network. No central authority has access to the fund. The community fund enables everyone to propose their ideas to the NavCoin community and to get paid to implement these ideas. Everyone can propose whatever they like (of course there is a higher rate of success if the proposal contributes to the NavCoin ecosystem ;-)). In fact, this article was sponsored by the NAV-Community by voting "yes" for my proposal. The fund works like this:
For a fee of 50 NAV, everyone can create and present his idea/proposal to the entire NavCoin network. The fee is here to help prevent spam attacks. Proposals can literally be anything - be it development, marketing or anything else you can some up with.
After creating the proposal, everyone contributing to the NavCoin network can then decide if they like the proposal of not. They vote with "Yes" or "No" for the acceptance of the proposal. Voting happens via staking. Every transaction that gets validated by you gives you one vote. This means that the more NAV you are staking, the higher your voting weight is.
The proposal stays in the state "Pending" until it is accepted or rejected. To be accepted, a proposal has to have a participation of at least 50% of all staked blocks and at least 75% of these votes have to be "Yes"-votes. Like-wise to be rejected a proposal need 50% participation of the network and 75% of these votes have to be "No"-votes. Additionally, if a proposal didn't pass after 6 voting cycles (about 6 weeks) it is also rejected.
After a proposal has been accepted, the creator of the proposal can start his work. When the work is finished, or at in the proposal defined checkpoints, the proposal creator can create a payment request for the full or part of the requested funds.
The NavCoin network can then again decide, if the work is what the creator promised to do and vote for the funds or reject the payment request because it was not what he promised. This mechanism ensures, that the funds are only release if the creator of the proposal did what he promised. The NavCoin network decides everything, there is no central authority which makes the community fund 100% decentralized.
The community fund is quite new but there have already been some proposals that were accepted like paying for the development & hosting of NAV block explorer, the creation and distribution of NAV car stickers to the community for free (or paid by the community fund), the funding of interns for NavCoin Core, translation of the website into other languages and YouTube videos. What ideas could you come up with? By the way: this article was also sponsored by the community fund :-)

Proof of Stake
Like said before, NavCoin uses the Proof of Stake algorithm to create and validate blocks. Participants of the NavCoin network can earn rewards by putting their coins to stake and thus validating blocks and securing the network. The reward used to be 4% fixed but recently changed with the implementation of PoSv3. Currently, rewards for stakers that are staking 24/7 is about 10% but it is dependent on how many people are staking. If more nodes come online, this reward will go down. If 90% of all NAVs would be at stake, stakers would still earn 4%.

Tutorials And Guidelines [3]
The NavCoin Core team pushes the community to contribute to the NavCoin ecosystem constantly. They emphasize that NavCoin is an open source project and everyone can contribute. The team tries to make it as easy as possible for the average person to contribute and thus created different tutorials and guidelines.

Tutorials To Contribute To The Website
The whole website is open source. Everyone can contribute to the website. The team created different guides for people to follow [4].

The NavCoin Developer Manifesto
The content creator core team has build a developer manifesto. It defines the values that should be uphold like for example that they will always operate in the best interest of the network. If defines the principles, purposes, scope of involvement and operational requirements [5].

The NavCoin Content Creation Manifesto
Similar to the developer manifesto, there is also a content creation manifesto. Again it defines the principles for creating content, the purpose, the scope of involvement and the operational requirements [6].

NavCoin Brand Guidelines
In addition to the content creation manifesto, there is also a brand guideline booklet. This should help content creators to create images, videos, articles etc. in the same style as the core team. It defines the NAV brand. The brand guidelines contain definitions, the language to use (words to use, words not to use), the tone of voice, what the community aspires to be and what we discourage to be. It also contains the logo pack which can be used in graphics etc. It describes correct logo spacing, logo placement, the colors of NAV and different web assets. It gives tips about gradients and overlays, the typefaces (with a font pack) and many more. Check it out yourself [7].

NavCoin Educational Series
The core team has decided to actively involve the community in the creation of new features. For this reason and to allow users to ask questions, they created the NavCoin Educational Series. The core team schedules an online live meetup which can be joined by everyone. On YouTube they do live-streams and explain upcoming features. Examples of these series are explanations for cold staking, static rewards (PoSv3) and the community fund. The community can ask questions live and the core team will answer them immediately.

Community
During the last year there have been an influx of software developers from the community starting to create features for NAV.

navexplorer.com
An examples is navexplorer.com which is programmed by community developer prodpeak and is a block explorer for NavCoin. Additionally, it functions as a interface to see what is going on in the community fund. It shows pending proposals and payment requests.

NEXT Wallet
The NEXT Wallet is an alternative wallet for NAV and other cryptocurrencies. It has a beautiful user interface and is additionally the easiest interface to interact with the community fund (create proposals, create payment requests and vote for proposals and payment requests). It is programmed by community developer sakdeniz who put hundreds of hours into it during last year.

There were also some marketing activities starting to emerge with the release of the community fund. Some of these were for example free stickers for everyone in the NAV community to stick to their car / shop / window etc. or YouTube videos of CryptoCandor and Cryptomoonie that explained the details of NAV. I am sure, that with the 500'000 NAV available in the community fund per year there will be an influx of gread ideas - development as well as marketing activities - that will be funded.

The Future

Introduction
These features are planned for the future. Many of the following features are part of the 2019 roadmap. Some will not be described in great detail because not much is known about them yet. I've still listed them as they are part of what is yet to come.

Features
Rimu - Improved Privacy Solution
NavCoin used to be a optional privacy coin. That means, that you could choose to send a transaction in private. NavCoin was criticized for the way it handles private payments because it relied on a few servers which didn't make it that decentralized. The technology was called "NavTech" and was a secondary blockchain that obscured the transaction and the amount that was sent. NavCoin Core is currently developing a new improved privacy solution that will make the private payment system completely trustless and districuted and runs at a protocol level. Alex of the NavCoin Core team has published a paper that describes this new privacy solution. It's called Zero Confidential Transactions and can be found here: https://www.researchgate.net/publication/330366788_ZeroCT_Improving_Zerocoin_with_Confidential_Transactions_and_more. What I want to highlight is the collaboration between Alex as the proposer of the solution and the Veil team, a Bitcoin Core developer and Moneros main cryptographer as reviewers. When the best work together, it will be interesting to see what the outcome is!

Valence Plattform [8]
Valence is an applied Blockchain platform that can help businesses realise the tangible benefits of blockchain. You can think of Valence as a platform with which you can build Anonymous Distributed Applications (aDapps) with. But Valence is a different kind of platform that enables developers to create new types of blockchain applications. The problem with current (turing complete) dApp platforms are their complexity and rigid nature. Security holes in smart contracts and scaling issues happen frequently [9].
Valence provides transitional pathways that let businesses migrate only part of their activities to the blockchain without having to restructure their entire business model [9].
Valence will provide a spectrum of blockchain application solutions which sit along the decentralized spectrum, offering businesses simple ways to dip their toes into the blockchain at minimal risk or complexity [9].
Thanks to the proof of stake nature of the Valence blockchain, more of a node's resources can be used for processing and routing application data which makes the platform faster and scalable.
Valence aims to make building blockchain applications as accessible to the general public as WordPress or Squarespace has made building websites.
The developers NavCoin and Valence aim to make Valence extremely easy to work with:
A Valence application could be an open source mobile or web application that submits unencrypted or encrypted data directly to the blockchain. The only configuration necessary for the app developer would be setting up the data structure. Once they've done that they can start writing to the blockchain immediately.
The Valence blockchain interface is language agnostic, meaning developers are free to build applications in whichever language they're familiar with, which greatly reduces the barrier to entry.
As the platform progresses, Valence will introduce more and more smart contract templates in collaboration with the development community. These will be like plugins that users can simply select and configure for their application, without having to reinvent the wheel and risk contract errors or spend countless hours of research to program them.

NavShopper
The following information is taken from the latest weekly news: NavShopper is a new project which will allow people to spend NavCoin on a growing list of retailers and service providers. NavShopper sits between traditional retailers accepting fiat and NavCoin users and purchases products on behalf of the user by managing the crypt-fiat conversion, payment and shipping. This project will unlock many more ways for people to spend NAV on existing websites/marketplaces without requiring each site to individually accept cryptocurrencies. Some of the prototypes we are working on include crediting your Uber account, buying products on Amazon and donating to charities.

Kauri Wallet
The Kauri Wallet aims to be an open-source, multi-currency wallet which functions as a foundation for other features.

Kauri Enhanced
Enhancements to the Kauri Wallet will allow multiple accounts, pin numbers, recurring payments and more.

Kauri DAEx
The Kauri DAEx is a Decentralised Atomic Exchange that utilises the features of the Kauri Wallet and enables users to create safe peer to peer atomic exchanges for any currency supported by the Kauri Wallet. NavDelta NavDelta will be a payment gateway that allows users to spend NAV at any business which accepts currencies supported by the Kauri Wallet. NavMorph NavMorph is a fusion of Rimu and Kauri DAEx and will allow to privately send every cryptocurrency supported by the Kauri Wallet.

Outro

If you have made it this far: Congratulations! You have learned about how NAV evolved, what its current state is and what the future will bring. To sum all up: NavCoin has made incredible progress during last year and released many long awaited features despite the bear market. Many more exciting features are yet to come and it's going to be very interesting to see where we will stand on this day next year.

Giveaway

Unfortunately, the giveaway was not possible in the cryptocurrency-subreddit because of their rules, so I'm doing it here :-) As a surprise, in the next 2 hours I am going to send some NAV to everyone who wants to try out the awesome features and NavPay you read about above.
To get your NAVs, all you have to do is the following:
If you liked the experience, I'd be happy to hear back from you :)

Information and FAQ

Welcome to the official IOTA subreddit.
If you are new you can find lots of information here, in the sidebar and please use the search button to see if your questions have been asked before. Please focus discussion on IOTA technology, ecosystem announcements, project development, apps, etc. Please direct help questions to /IOTASupport, and price discussions and market talk to /IOTAmarkets.
Before getting started it is recommended to read the IOTA_Whitepaper.pdf. I also suggest watching these videos first to gain a better understanding.
IOTA BREAKDOWN: The Tangle Vs. Blockchain Explained
IOTA tutorial 1: What is IOTA and some terminology explained

Information

Firstly, what is IOTA?

IOTA is an open-source distributed ledger protocol launched in 2015 that goes 'beyond blockchain' through its core invention of the blockless ‘Tangle’. The IOTA Tangle is a quantum-resistant Directed Acyclic Graph (DAG), whose digital currency 'iota' has a fixed money supply with zero inflationary cost.
IOTA uniquely offers zero-fee transactions & no fixed limit on how many transactions can be confirmed per second. Scaling limitations have been removed, since throughput grows in conjunction with activity; the more activity, the more transactions can be processed & the faster the network. Further, unlike blockchain architecture, IOTA has no separation between users and validators (miners / stakers); rather, validation is an intrinsic property of using the ledger, thus avoiding centralization.
IOTA is focused on being useful for the emerging machine-to-machine (m2m) economy of the Internet-of-Things (IoT), data integrity, micro-/nano- payments, and other applications where a scalable decentralized system is warranted.
More information can be found here.

Seeds

A seed is a unique identifier that can be described as a combined username and password that grants you access to your IOTA.
Your seed is used to generate the addresses and private keys you will use to store and send IOTA, so this should be kept private and not shared with anyone. If anyone obtains your seed, they can generate the private keys associated with your addresses and access your IOTA.

Non reusable addresses

Contrary to traditional blockchain based systems such as Bitcoin, where your wallet addresses can be reused, IOTA's addresses should only be used once (for outgoing transfers). That means there is no limit to the number of transactions an address can receive, but as soon as you've used funds from that address to make a transaction, this address should not be used anymore.
Why?
When an address is used to make an outgoing transaction, a random 50% of the private key of that particular address is revealed in the transaction signature, which effectively reduces the security of the key. A typical IOTA private key of 81-trits has 2781 possible combinations ( 8.7 x 10115 ) but after a single use, this number drops to around 2754 ( 2 x 1077 ), which coincidentally is close to the number of combinations of a 256-bit Bitcoin private key. Hence, after a single use an IOTA private key has about the same level of security as that of Bitcoin and is basically impractical to brute-force using modern technology. However, after a second use, another random 50% of the private key is revealed and the number of combinations that an attacker has to guess decreases very sharply to approximately 1.554 (~3 billion) which makes brute-forcing trivial even with an average computer.
Note: your seed is never revealed at at time; only private keys specific to each address.
The current light wallet prevents address reuse automatically for you by doing 2 things:
  1. Whenever you make an outgoing transaction from an address that does not consume its entire balance (e.g. address holds 10 Mi but you send only 5 Mi), the wallet automatically creates a new address and sends the change (5 Mi) to the new address.
  2. The wallet prevents you from performing a second outgoing transaction using the same address (it will display a “Private key reuse detected!” error).
This piggy bank diagram can help visualize non reusable addresses. imgur link
[Insert new Safe analogy].

Address Index

When a new address is generated it is calculated from the combination of a seed + Address Index, where the Address Index can be any positive Integer (including "0"). The wallet usually starts from Address Index 0, but it will skip any Address Index where it sees that the corresponding address has already been attached to the tangle.

Private Keys

Private keys are derived from a seeds key index. From that private key you then generate an address. The key index starting at 0, can be incremented to get a new private key, and thus address.
It is important to keep in mind that all security-sensitive functions are implemented client side. What this means is that you can generate private keys and addresses securely in the browser, or on an offline computer. All libraries provide this functionality.
IOTA uses winternitz one-time signatures, as such you should ensure that you know which private key (and which address) has already been used in order to not reuse it. Subsequently reusing private keys can lead to the loss of funds (an attacker is able to forge the signature after continuous reuse).
Exchanges are advised to store seeds, not private keys.

FAQ

Buying IOTA

How do I to buy IOTA?

Currently not all exchanges support IOTA and those that do may not support the option to buy with fiat currencies.
Visit this website for a Guide: How to buy IOTA
or Click Here for a detailed guide made by 450LbsGorilla

Cheapest way to buy IOTA?

You can track the current cheapest way to buy IOTA at IOTA Prices.
It tells you where & how to get the most IOTA for your money right now. There's an overview of the exchanges available to you and a buying guide to help you along.
IOTAPrices.com monitors all major fiat exchanges for their BTC & ETH rates and combines them with current IOTA rates from IOTA exchanges for easy comparison. Rates are taken directly from each exchange's official websocket. For fiat exchanges or exchanges that don't offer websockets, rates are refreshed every 60 seconds.

What is MIOTA?

MIOTA is a unit of IOTA, 1 Mega IOTA or 1 Mi. It is equivalent to 1,000,000 IOTA and is the unit which is currently exchanged.
We can use the metric prefixes when describing IOTA e.g 2,500,000,000 i is equivalent to 2.5 Gi.
Note: some exchanges will display IOTA when they mean MIOTA.

Can I mine IOTA?

No you can not mine IOTA, all the supply of IOTA exist now and no more can be made.
If you want to send IOTA, your 'fee' is you have to verify 2 other transactions, thereby acting like a minenode.

Storing IOTA

Where should I store IOTA?

It is not recommended to store large amounts of IOTA on the exchange as you will not have access to the private keys of the addresses generated.

What is a seed?

A seed is a unique identifier that can be described as a combined username and password that grants you access to your wallet.
Your seed is used to generate the addresses linked to your account and so this should be kept private and not shared with anyone. If anyone obtains your seed, they can login and access your IOTA.

How do I generate a seed?

You must generate a random 81 character seed using only A-Z and the number 9.
It is recommended to use offline methods to generate a seed, and not recommended to use any non community verified techniques. To generate a seed you could:

On a Linux Terminal

use the following command:
 cat /dev/urandom |tr -dc A-Z9|head -c${1:-81} 

On a Mac Terminal

use the following command:
 cat /dev/urandom |LC_ALL=C tr -dc 'A-Z9' | fold -w 81 | head -n 1 

With KeePass on PC

A helpful guide for generating a secure seed on KeePass can be found here.

With a dice

Dice roll template

Is my seed secure?

  1. All seeds should be 81 characters in random order composed of A-Z and 9.
  2. Do not give your seed to anyone, and don’t keep it saved in a plain text document.
  3. Don’t input your seed into any websites that you don’t trust.
Is Someone Going To Guess My IOTA Seed?
What are the odds of someone guessing your seed?
  • IOTA seed = 81 characters long, and you can use A-Z, 9
  • Giving 2781 = 8.7x10115 possible combinations for IOTA seeds
  • Now let's say you have a "super computer" letting you generate and read every address associated with 1 trillion different seeds per second.
  • 8.7x10115 seeds / 1x1012 generated per second = 8.7x10103 seconds = 2.8x1096 years to process all IOTA seeds.

Why does balance appear to be 0 after a snapshot?

When a snapshot happens, all transactions are being deleted from the Tangle, leaving only the record of how many IOTA are owned by each address. However, the next time the wallet scans the Tangle to look for used addresses, the transactions will be gone because of the snapshot and the wallet will not know anymore that an address belongs to it. This is the reason for the need to regenerate addresses, so that the wallet can check the balance of each address. The more transactions were made before a snapshot, the further away the balance moves from address index 0 and the more addresses have to be (re-) generated after the snapshot.

What happens if you reuse an address?

It is important to understand that only outgoing transactions reveal the private key and incoming transactions do not. If you somehow manage to receive iotas using an address after having used it previously to send iotas—let's say your friend sends iotas to an old address of yours—these iotas may be at risk.
Recall that after a single use an iota address still has the equivalent of 256-bit security (like Bitcoin) so technically, the iotas will still be safe if you do not try to send them out. However, you would want to move these iotas out eventually and the moment you try to send them out, your private key will be revealed a second time and it now becomes feasible for an attacker to brute-force the private key. If someone is monitoring your address and spots a second use, they can easily crack the key and then use it to make a second transaction that will compete with yours. It then becomes a race to see whose transaction gets confirmed first.
Note: The current wallet prevents you from reusing an address to make a second transaction so any iotas you receive with a 'used' address will be stuck. This is a feature of wallet and has nothing to do with the fundamental workings of IOTA.

Sending IOTA

What does attach to the tangle mean?

The process of making an transaction can be divided into two main steps:
  1. The local signing of a transaction, for which your seed is required.
  2. Taking the prepared transaction data, choosing two transactions from the tangle and doing the POW. This step is also called “attaching”.
The following analogy makes it easier to understand:
Step one is like writing a letter. You take a piece of paper, write some information on it, sign it at the bottom with your signature to authenticate that it was indeed you who wrote it, put it in an envelope and then write the recipient's address on it.
Step two: In order to attach our “letter” (transaction), we go to the tangle, pick randomly two of the newest “letters” and tie a connection between our “letter” and each of the “letters” we choose to reference.
The “Attach address” function in the wallet is actually doing nothing else than making an 0 value transaction to the address that is being attached.

Why is my transaction pending?

IOTA's current Tangle implementation (IOTA is in constant development, so this may change in the future) has a confirmation rate that is ~66% at first attempt.
So, if a transaction does not confirm within 1 hour, it is necessary to "reattach" (also known as "replay") the transaction one time. Doing so one time increases probability of confirmation from ~66% to ~89%.
Repeating the process a second time increases the probability from ~89% to ~99.9%.

How do I reattach a transaction.

Reattaching a transaction is different depending on where you send your transaction from. To reattach using the GUI Desktop wallet follow these steps:
  1. Click 'History'.
  2. Click 'Show Bundle' on the 'pending' transaction.
  3. Click 'Reattach'.
  4. Click 'Rebroadcast'. (optional, usually not required)
  5. Wait 1 Hour.
  6. If still 'pending', repeat steps 1-5 once more.

Does the private key get revealed each time you reattach a transaction?

When you use the reattach function in the desktop wallet, a new transaction will be created but it will have the same signature as the original transaction and hence, your private key will not revealed a second time.

What happens to pending transactions after a snapshot?

IOTA Network and Nodes

What incentives are there for running a full node?

IOTA is made for m2m economy, once wide spread adoption by businesses and the IOT, there will be a lot of investment by these businesses to support the IOTA network. In the meantime if you would like to help the network and speed up p2p transactions at your own cost, you can support the IOTA network by setting up a Full Node.
Running a full node also means you don't have to trust a 3rd party light node provider. By running a full node you get to take advantage of new features that might not be installed on 3rd party nodes.

How to set up a full node?

To set up a full node you will need to follow these steps:
  1. Download the full node software: either GUI, or headless CLI for lower system requirements and better performance.
  2. Get a static IP for your node.
  3. Join the network by adding 7-9 neighbours.
  4. Keep your full node up and running as much as possible.
A detailed user guide on how to set up a VTS IOTA Full Node from scratch can be found here.

How do I get a static IP?

To learn how to setup a hostname (~static IP) so you can use the newest IOTA versions that have no automated peer discovery please follow this guide.

How do I find a neighbour?

Are you a single IOTA full node looking for a partner? You can look for partners in these place:

The History, The Current State And The Future Of NavCoin

This is it. If you're interested to see what NAV is all about, this is the ultimate guide for you. You will learn about the history of NavCoin and how it evolved. You will learn about the current state and features of NavCoin and you will learn about the exciting new features that are planned and coming up in the (near) future.
So buckle up, this is going to be a long ride!

Introduction - What is NavCoin?


The History

Introduction
The following chapter will summarize and break down the history of NavCoin in a few sentences. NAV started a long time ago, went through rebrandings and changes of the core team before it became what it is today.

SummerCoin
NavCoin was initially first introduced under the name SummerCoin on April 23 in 2014. SummerCoin was a fork of the Bitcoin blockchain. It used to have a PoW/PoS hybrid algorithm with a block time of 45 seconds.

SummerCoinV2 /NavajoCoin
Soon after the initial launch of SummerCoin, the original developer left and SoopY (soopy452000 on bitcointalk) took over as the main developer and rebranded the project to SummerCoinV2 respectively NavajoCoin and introduced new features.
The name NavajoCoin was chosen in honor of the Navajo Code Talker. The unbreakable Navajo code was used to encrypt highly classified military information and commands and decrypt the same in WW II.
SoopY introduced a technology which allowed sending transactions anonymously and private. This technology was called "Navajo Anonymous Technology". SoopY also released a new wallet and set the Proof of Stake rewards at 10% for the first year, 5% for the second year and 2% for every year after.

NavCoin
On August 12, 2014, Craig (current lead core developer, pakage on bitcointalk) started to get involved with NAV by helping to set up a website [10].
It was officially announced that Craig joined the core team as a "Wallet & Web Developer" on November 06, 2014.
The last tokenswap and restart of the blockchain of NAV happened on May 12, 2016.
Soon later, SoopY stopped showing up and Craig stepped into the role of the lead core developer. Since then, Craig has assembled a strong team with which he built NavCoin into what it is today.
Currently, Craig and the NavCoin Core team is located in New Zealand and they are actively developing many ground-braking features which differentiate NAV from other cryptocurrencies. You will read more about that later in this article.

The Current State

Introduction
The year 2018 has been a thriving year for the NavCoin ecosystem. Despite the USD price of NAV not reflecting it, in 2018 the core team has developed a whole bunch of new features. Also the core content creators published the first official guidelines that function as an orientation guide for community content creators. This chapter will give you an overview of the current team, the features, the prior mentioned guidelines and the community of NavCoin.

Core Team [1]
Last year, the core team has grown alot. It contains of developers, content creators and interns. The core team are employees of Encrypt S, the New Zealand's leading blockchain R&D lab. Encrypt S is developing blockchain solutions since 2014 and values building open-source software highly.

Craig MacGregor - Chief Executive Officer
Craig is the CEO of Encrypt S and the founder of NavCoin. He is one of the world's most experienced blockchain developers. Craig founded NavCoin in 2014 and is developing software for it since then. He has assembled a strong team of like-minded people. Craig also speaks at seminars and conferenced. Some of the companies and conferences he did blockchain education sessions at are Oracle, Xero, Air New Zealand, Blok Tex and trademe. Together with the team, he is also doing a education series on YouTube where he explains upcoming features in-depth for the community.

Alex Vazquez - Chief Technical Officer
Alex is the CTO of Encrypt S and the most active contributor to the NavCoin core Github. He has incredible knowledge of blockchains and proposes and implements solutions for challenges and features. He supports community developers frequently and answers any questions of the community thoroughly. Like Craig, Alex is developing software for the NavCoin ecosystem for a very long time. Alex speaks at universities at times and educates students about the blockchain technology.

Paul Sanderson - Lead Software Engineer
Paul is the Lead Software Engineer at Encrypt S. He has a flair for technology. His technical and management skills are perfectly suited for consultancy and investment advising. He also frequently contributes to the NavCoin core source code.

Rowan Savage - Senior Software Engineer
Rowan is a full stack software engineer with more than a decade experience in developing complex front-end web applications. He joined Encrypt S in February 2018 and has since been involved in the Valence Plattform, the Kauri Wallet and NavCoin Core. You will read more about these feature/projects later.

Carter Xiao - Lead UX/UI Designer
Carter specializes in user-centric design and is also very talented with 3D animation, motion graphics and programming. One of NavCoins core principle is "Simplifying Crypto" and UX/UI is a very important part of that.

Matt Paul - Software Engineer
Like Rowan, Matt is a full stack Software Engineer. He joined the core team in Mai 2017 and has since worked on NavPay, NavPi, the Kauri Wallet and NavCoin Core. Kieren Hyland - Chief Strategy Officer Kieren is one of the employees that are working for Encrypt S for a very long time. He is the CSO and is a digital strategist and growth hacker with a passion for new technology and has a lot of experience in online marketing. Laura Harris - Creative Director Laura has a combination of commercial and creative flair. She manages the social media accounts for NavCoin and ensures, that NavCoins' message is always powerful, relevant and distinctive. John Darby - Content Creator John is an internationally awarded Technology and Financial sector marketing communications specialist. He is one of the Core Content Creators for NavCoin.

Features of NavCoin [2]
The following features are currently available and have been developed in the last months and years. It is sorted from newest to oldest.

Static Block Reward
The soft-fork for the enabling of static block rewards have been accepted and became active recently at 5th January 2019. This means, that the block reward was changed from a percentage based reward to a static reward. This will incentivize the stakers to have their node online 24/7 which increased the security of the network. It also aligns NavCoin with the PoSv3 specification. With this implementation, the yearly inflation will be 3.6% currently and will exponentionally decrease because of the static value of the rewards. Every staked block will now give the staker 2 NAV. Depending on how many people are staking, the yearly percentage varies. With the network weight currently being around 20'000'000 NAV, stakers earn around 10% rewards from staking 24/7.

Cold staking
To provide extra security to participants in the staking process in the NavCoin network, the core team decided to implement cold staking. This allows to store NAV offline and still be able to sign staking inputs. Looking forward, a possible integration into the Ledger Nano S would mean, that one can stake NAV securely from a offline hardware wallet. How cool is that?

OpenAlias
One of the core principle of NAV is to simplify cryptocurrencies. Many non-technical people are deterred from the long, cryptic addresses used in wallets. When sending funds, you have to make sure that every single letter and digit is correct which is nerve-wracking for the average person. NavCoin has implemented OpenAlias, which allows to transform the wallet address into a email-like form. Everyone can register a name like "[crypto[email protected]](mailto:[email protected])". Funds can then be sent to this name, which makes sending crypto much easier and less error-prone.

Community Fund
This is the one big feature I was most excited about. NavCoin core has implemented the first fully decentralized community fund. Acceptance of proposals and release of funds is all approved by the decentralized network. No central authority has access to the fund. The community fund enables everyone to propose their ideas to the NavCoin community and to get paid to implement these ideas. Everyone can propose whatever they like (of course there is a higher rate of success if the proposal contributes to the NavCoin ecosystem ;-)). In fact, this article was sponsored by the NAV-Community by voting "yes" for my proposal. The fund works like this:
For a fee of 50 NAV, everyone can create and present his idea/proposal to the entire NavCoin network. The fee is here to help prevent spam attacks. Proposals can literally be anything - be it development, marketing or anything else you can some up with.
After creating the proposal, everyone contributing to the NavCoin network can then decide if they like the proposal of not. They vote with "Yes" or "No" for the acceptance of the proposal. Voting happens via staking. Every transaction that gets validated by you gives you one vote. This means that the more NAV you are staking, the higher your voting weight is.
The proposal stays in the state "Pending" until it is accepted or rejected. To be accepted, a proposal has to have a participation of at least 50% of all staked blocks and at least 75% of these votes have to be "Yes"-votes. Like-wise to be rejected a proposal need 50% participation of the network and 75% of these votes have to be "No"-votes. Additionally, if a proposal didn't pass after 6 voting cycles (about 6 weeks) it is also rejected.
After a proposal has been accepted, the creator of the proposal can start his work. When the work is finished, or at in the proposal defined checkpoints, the proposal creator can create a payment request for the full or part of the requested funds.
The NavCoin network can then again decide, if the work is what the creator promised to do and vote for the funds or reject the payment request because it was not what he promised. This mechanism ensures, that the funds are only release if the creator of the proposal did what he promised. The NavCoin network decides everything, there is no central authority which makes the community fund 100% decentralized.
The community fund is quite new but there have already been some proposals that were accepted like paying for the development & hosting of NAV block explorer, the creation and distribution of NAV car stickers to the community for free (or paid by the community fund), the funding of interns for NavCoin Core, translation of the website into other languages and YouTube videos. What ideas could you come up with? By the way: this article was also sponsored by the community fund :-)

Proof of Stake
Like said before, NavCoin uses the Proof of Stake algorithm to create and validate blocks. Participants of the NavCoin network can earn rewards by putting their coins to stake and thus validating blocks and securing the network. The reward used to be 4% fixed but recently changed with the implementation of PoSv3. Currently, rewards for stakers that are staking 24/7 is about 10% but it is dependent on how many people are staking. If more nodes come online, this reward will go down. If 90% of all NAVs would be at stake, stakers would still earn 4%.

Tutorials And Guidelines [3]
The NavCoin Core team pushes the community to contribute to the NavCoin ecosystem constantly. They emphasize that NavCoin is an open source project and everyone can contribute. The team tries to make it as easy as possible for the average person to contribute and thus created different tutorials and guidelines.

Tutorials To Contribute To The Website
The whole website is open source. Everyone can contribute to the website. The team created different guides for people to follow [4].

The NavCoin Developer Manifesto
The content creator core team has build a developer manifesto. It defines the values that should be uphold like for example that they will always operate in the best interest of the network. If defines the principles, purposes, scope of involvement and operational requirements [5].

The NavCoin Content Creation Manifesto
Similar to the developer manifesto, there is also a content creation manifesto. Again it defines the principles for creating content, the purpose, the scope of involvement and the operational requirements [6].

NavCoin Brand Guidelines
In addition to the content creation manifesto, there is also a brand guideline booklet. This should help content creators to create images, videos, articles etc. in the same style as the core team. It defines the NAV brand. The brand guidelines contain definitions, the language to use (words to use, words not to use), the tone of voice, what the community aspires to be and what we discourage to be. It also contains the logo pack which can be used in graphics etc. It describes correct logo spacing, logo placement, the colors of NAV and different web assets. It gives tips about gradients and overlays, the typefaces (with a font pack) and many more. Check it out yourself [7].

NavCoin Educational Series
The core team has decided to actively involve the community in the creation of new features. For this reason and to allow users to ask questions, they created the NavCoin Educational Series. The core team schedules an online live meetup which can be joined by everyone. On YouTube they do live-streams and explain upcoming features. Examples of these series are explanations for cold staking, static rewards (PoSv3) and the community fund. The community can ask questions live and the core team will answer them immediately.

Community
During the last year there have been an influx of software developers from the community starting to create features for NAV.

navexplorer.com
An examples is navexplorer.com which is programmed by community developer prodpeak and is a block explorer for NavCoin. Additionally, it functions as a interface to see what is going on in the community fund. It shows pending proposals and payment requests.

NEXT Wallet
The NEXT Wallet is an alternative wallet for NAV and other cryptocurrencies. It has a beautiful user interface and is additionally the easiest interface to interact with the community fund (create proposals, create payment requests and vote for proposals and payment requests). It is programmed by community developer sakdeniz who put hundreds of hours into it during last year.

There were also some marketing activities starting to emerge with the release of the community fund. Some of these were for example free stickers for everyone in the NAV community to stick to their car / shop / window etc. or YouTube videos of CryptoCandor and Cryptomoonie that explained the details of NAV. I am sure, that with the 500'000 NAV available in the community fund per year there will be an influx of gread ideas - development as well as marketing activities - that will be funded.

The Future

Introduction
These features are planned for the future. Many of the following features are part of the 2019 roadmap. Some will not be described in great detail because not much is known about them yet. I've still listed them as they are part of what is yet to come.

Rimu - Improved Privacy Solution
NavCoin used to be a optional privacy coin. That means, that you could choose to send a transaction in private. NavCoin was criticized for the way it handles private payments because it relied on a few servers which didn't make it that decentralized. The technology was called "NavTech" and was a secondary blockchain that obscured the transaction and the amount that was sent. NavCoin Core is currently developing a new improved privacy solution that will make the private payment system completely trustless and districuted and runs at a protocol level. Alex of the NavCoin Core team has published a paper that describes this new privacy solution. It's called Zero Confidential Transactions and can be found here: https://www.researchgate.net/publication/330366788_ZeroCT_Improving_Zerocoin_with_Confidential_Transactions_and_more. What I want to highlight is the collaboration between Alex as the proposer of the solution and the Veil team, a Bitcoin Core developer and Moneros main cryptographer as reviewers. When the best work together, it will be interesting to see what the outcome is!

Valence Plattform [8]
Valence is an applied Blockchain platform that can help businesses realise the tangible benefits of blockchain. You can think of Valence as a platform with which you can build Anonymous Distributed Applications (aDapps) with. But Valence is a different kind of platform that enables developers to create new types of blockchain applications. The problem with current (turing complete) dApp platforms are their complexity and rigid nature. Security holes in smart contracts and scaling issues happen frequently [9].
Valence provides transitional pathways that let businesses migrate only part of their activities to the blockchain without having to restructure their entire business model [9].
Valence will provide a spectrum of blockchain application solutions which sit along the decentralized spectrum, offering businesses simple ways to dip their toes into the blockchain at minimal risk or complexity [9].
Thanks to the proof of stake nature of the Valence blockchain, more of a node's resources can be used for processing and routing application data which makes the platform faster and scalable.
Valence aims to make building blockchain applications as accessible to the general public as WordPress or Squarespace has made building websites.
The developers NavCoin and Valence aim to make Valence extremely easy to work with:
A Valence application could be an open source mobile or web application that submits unencrypted or encrypted data directly to the blockchain. The only configuration necessary for the app developer would be setting up the data structure. Once they've done that they can start writing to the blockchain immediately.
The Valence blockchain interface is language agnostic, meaning developers are free to build applications in whichever language they're familiar with, which greatly reduces the barrier to entry.
As the platform progresses, Valence will introduce more and more smart contract templates in collaboration with the development community. These will be like plugins that users can simply select and configure for their application, without having to reinvent the wheel and risk contract errors or spend countless hours of research to program them.

NavShopper
The following information is taken from the latest weekly news: NavShopper is a new project which will allow people to spend NavCoin on a growing list of retailers and service providers. NavShopper sits between traditional retailers accepting fiat and NavCoin users and purchases products on behalf of the user by managing the crypt-fiat conversion, payment and shipping. This project will unlock many more ways for people to spend NAV on existing websites/marketplaces without requiring each site to individually accept cryptocurrencies. Some of the prototypes we are working on include crediting your Uber account, buying products on Amazon and donating to charities.

Kauri Wallet
The Kauri Wallet aims to be an open-source, multi-currency wallet which functions as a foundation for other features.

Kauri Enhanced
Enhancements to the Kauri Wallet will allow multiple accounts, pin numbers, recurring payments and more.

Kauri DAEx
The Kauri DAEx is a Decentralised Atomic Exchange that utilises the features of the Kauri Wallet and enables users to create safe peer to peer atomic exchanges for any currency supported by the Kauri Wallet. NavDelta NavDelta will be a payment gateway that allows users to spend NAV at any business which accepts currencies supported by the Kauri Wallet. NavMorph NavMorph is a fusion of Rimu and Kauri DAEx and will allow to privately send every cryptocurrency supported by the Kauri Wallet.

Outro

If you have made it this far: Congratulations! You have learned about how NAV evolved, what its current state is and what the future will bring. To sum all up: NavCoin has made incredible progress during last year and released many long awaited features despite the bear market. Many more exciting features are yet to come and it's going to be very interesting to see where we will stand on this day next year.

Giveaway

Unfortunately, the giveaway was not possible in the cryptocurrency-subreddit because of their rules, so I'm doing it here :-) As a surprise, in the next few hours I am going to send some NAV to everyone who wants to try out the awesome features you have read about above.
To get your NAVs, all you have to do is the following:
If you liked the experience, I'd be happy to hear back from you :)

Getting Started

What is Waltonchain?

The Waltonchain Foundation is building a cross-industry, cross-data sharing platform by integrating Blockchain with the Internet of Things through self-developed RFID Chips with intellectual property rights.
The in-house developed Waltonchain RFID chips integrate a proprietary, genuine random number generator and an asymmetric encryption logic and hardware signature circuit, all of which are patent-protected.
The combination of self-developed RFID chips and the Waltonchain blockchain will ultimately achieve the interconnection of all things and create a genuine, believable, traceable businessmodel with totally shared data and transparent information.
Waltonchain will unfold a new era of the Value Internet of Things (VIoT).

The Project

The Waltonchain team has formulated a 4-phase development plan, starting from infrastructure platform establishment to gradually incorporating retail, logistics and product manufacturing, and to finally achieving the full coverage of the business ecosystem.
 
As for the phase 1.0 of the project, the team has developed the clothing system integration scheme based on RFID. The application scenarios at phase 1.0 will establish Golden demonstration template
At phase 2.0, our RFID beacon chip will be massproduced and can be used in clothing, B2C retail and logistics.
At phase 3.0, manufacturers will achieve traceable customization of intelligent packaging.
At the project phase 4.0, with the upgrading and iteration of assets information collection hardware and improvement of blockchain data structure, all assets can be registered in Waltonchain in the future.

Fantasy Coin ICO Review

Fantasy Coin ICO Review
https://preview.redd.it/42crc5vv2vr21.png?width=727&format=png&auto=webp&s=c14c22cd50310df14e251dcd751b94cf8cf8b2b2
It is difficult to imagine what awaits us in the near future, if already now the world is implementing a huge variety of incredible and unique projects, each of which was once something incomprehensible and unreal. However, over time, they all found strength and became more than real than ever.
Today we will talk about one very interesting project FANTASY and they have created the setting of feature film & TV series that you can visit in VR. A provocative film experiment where you are the star topic as virtual reality and all its features.
It turns out quite recently, humanity could only dream of experiencing new and previously unknown emotions caused by visual effects from virtual reality. Now in the world there are a large number of technologies that contribute to the transmission of high-quality signals, as well as vivid impressions from the interaction with virtual reality.
ABOUT FANTASY COIN
Fantasy Coin” (FXXX), Fantasy is a fully-functional, adult narrative-driven mixed-reality (VAR) city broken into 19 themed red-light district sectors on an exact replica of Mars. Accessible in VR, AR and on the normal web, the city is a fantastically designed ‘Red Light Strip’ where each street is uniquely, tantalizingly themed and behind every window lies a different fantasy. In Fantasy, you can follow your desires and embody yourself inside them: be a guy, be a girl, shed your inhibitions and ‘FXXX with your alter ego’.
Powered by Fantasy Coin (FXXX), explore the immersive city of Fantasy as a dream come to life; a dream where adult stars compete to make you the subject of their desires. Step into their red light window “apartments” and become the star. There is only one catch! You must earn enough “Fantasy” [Fantasy Coin (FXXX)] to stay in the story. If your FXXX runs out, access will be denied and you’ll need to earn more to continue.
The Fantasy world, is a city of erotic dreams delivered into 19 themed sectors, Each sector comprises of stars living in Red Light Window apartments - luring you into your own fantasies. Step inside and you’ll discover that these are not just apartments, but portals into fantasy worlds that will take you as far in as you’re willing to go. Can you find your way out? Do you even want to? Get lost in your own seamless adventure. Visitors earn FANTASY’ as a reward by watching erotic content provided by brands trying to lure you into their zones. Simply gaze’ at billboards and store front windows, trigger content and earn rewards for the time you are engaged. Walk around, shop through the fantasies and inhibitions that rule your mind - and then step back into the FANTASY zone.
Audiences immerse themselves in free content and earn Fxxx credits/ rewards for the actual time engaged. This is calculated on a per second using the 'gaze' mechanic - ie audiences trigge immerse themselves in content simply by looking . This model makes for a new and seamless experience inside VR adult worlds. But what this model does for the adult stars themselves is a true game changer. The key USP for adult stars is that VR content gives adult stars the ability to re-use a scene over and over while giving the appearance of being live 24/7.
An adult star on average has to have sex 5 times to make the maximum amount of money from an porno movie - after which they can no longer make money from it. Using Fxxx they only have to have sex once, and scene can make money for them 1000 x over . The male / female body can be embodied again and againThis allows adult stars to make money while they sleep.

How The Sale Works?
The land sale takes place in four phases.
REGISTER YOUR INTEREST
Put your name on the white-list for 30% bonus
BID ON PROPERTY USING ETH OR GZE
Make the winning bid in time allotted and the property is yours. ‣ Bids with Gaze Coin receive up to 30 % bonus. Get on white list now !
RECEIEVE ERC 721 RENT TOKENS
Buyers receive a unique ERC 721 ‘Rent’ Token unique to each plot of land. By sending this token to another party they transfer rights to earn FXXX to another party, taking a revenue share.
RECEIVE FXXX COINS FROM USER GROWTH POOL
All land buyers will receive FXXX coins from the user growth pool pro rata according to the value of their purchase.
Property in Fantasy is known as Dreamspaces where VR content, VIP doorways to premium content & wormholes to connecting spaces are stored. Property owners may create their own dream theme’ inside their dream space’ selecting from a series of templates or employ a builder. Owners can choose to rent out their Dreamspaces to whoever they want using an ERC721 rent’ token and will earn a simple revenue share charged on all transactions that occur within their Dreamspace.
FXXX Coin uses eye tracking to create a transaction that rewards owners for simply looking (gaze triggering content). For example, owners of apartments, billboards, or other real estate in high-traffic areas will receive rewards for engagement occurring on the real estate (i.e. a player watching an ad). As well as empty lots of land where you can build whatever your heart desires, every sector has a limited number of the following.

Gaze Coin technology rewards property owners for user engagement. Owners of land, billboards, benches or other real estate in high-traffic areas will receive revenues corresponding to the engagement occurring on the real estate (i.e. a vieweplayer watching an ad). In the case of VR or WebGL games, Fantasy Coin uses eye tracking to reward players for simply looking (gaze triggering content).
Properties in Fantasy are known as Dreamspaces — where dreams, wormholes and content are stored. Dreamspaces must be purchased by either Gaze Coin (ERC20) or Fantasy Coin (ERC20) and then converted into a unique property ERC721 token. Dreamspace owners may either serve their own content or “rent out” the space for others to serve theirs. Owners that rent out their Dreamspace use an ERC721 ‘rent’ token and earn a simple revenue share charged on all transactions that occur within the Dreamspace.

https://preview.redd.it/y9w114h11vr21.jpg?width=640&format=pjpg&auto=webp&s=066c460bb16fefc3427cd742a94a89bf648ac500
Fantasy Coin (FXXX) is a fully-functional, adult narrative-driven mixed-reality (VAR) city broken into 19 themed red-light district sectors on an exact replica of Mars. Accessible in VR, AR and on the normal web, the city is a fantastically designed ‘Red Light Strip’ where each street is uniquely, tantalizingly themed and behind every window lies a different fantasy. In Fantasy, you can follow your desires and embody yourself inside them: be a guy, be a girl, shed your inhibitions and ‘FXXX with your alter ego.
The word Fantasy, is a city of erotic dreams delivered into 19 themed sectors, Each sector comprises of stars living in Red Light Window apartments - luring you into your own fantasies. Step inside and you’ll discover that these are not just apartments, but portals into fantasy worlds that will take you as far in as you’re willing to go. Can you find your way out? Do you even want to? Get lost in your own seamless adventure. Visitors earn FANTASY’ as a reward by watching erotic content provided by brands trying to lure you into their zones. Simply gaze’ at billboards and store front windows, trigger content and earn rewards for the time you are engaged. Walk around, shop through the fantasies and inhibitions that rule your mind - and then step back into the FANTASY zone.
Audiences immerse themselves in free content and earn Fxxx credits/ rewards for the actual time engaged. This is calculated on a per second using the 'gaze' mechanic - ie audiences trigge immerse themselves in content simply by looking . This model makes for a new and seamless experience inside VR adult worlds. But what this model does for the adult stars themselves is a true game changer. The key USP for adult stars is that VR content gives adult stars the ability to re-use a scene over and over while giving the appearance of being live 24/7.
An adult star on average has to have sex 5 times to make the maximum amount of money from an porno movie - after which they can no longer make money from it. Using Fxxx they only have to have sex once, and scene can make money for them 1000 x over . The male / female body can be embodied again and againThis allows adult stars to make money while they sleep.
How The Sale Works?
The land sale takes place in four phases.

RECEIEVE ERC 721 RENT TOKENS
Buyers receive a unique ERC 721 ‘Rent’ Token unique to each plot of land. By sending this token to another party they transfer rights to earn FXXX to another party, taking a revenue share.
RECEIVE FXXX COINS FROM USER GROWTH POOL
All land buyers will receive FXXX coins from the user growth pool pro rata according to the value of their purchase.
Property in Fantasy is known as Dreamspaces where VR content, VIP doorways to premium content & wormholes to connecting spaces are stored. Property owners may create their own dream theme’ inside their dream space’ selecting from a series of templates or employ a builder. Owners can choose to rent out their Dreamspaces to whoever they want using an ERC721 rent’ token and will earn a simple revenue share charged on all transactions that occur within their Dreamspace.
FXXX Coin uses eye tracking to create a transaction that rewards owners for simply looking (gaze triggering content). For example, owners of apartments, billboards, or other real estate in high-traffic areas will receive rewards for engagement occurring on the real estate (i.e. a player watching an ad). As well as empty lots of land where you can build whatever your heart desires, every sector has a limited number of the following.
Red light window apartments (includes the loft apartments up stairs)
Penthouse apartments
Strip clubs
Disco-tech / Night clubs
Massage parlors
Peep shows
Red light cinemas
Billboards
Vending machines
Tool sheds
Saunas
Entire City blocks
Town Squares
Gaze Coin technology rewards property owners for user engagement. Owners of land, billboards, benches or other real estate in high-traffic areas will receive revenues corresponding to the engagement occurring on the real estate (i.e. a vieweplayer watching an ad). In the case of VR or WebGL games, Fantasy Coin uses eye tracking to reward players for simply looking (gaze triggering content).
Properties in Fantasy are known as Dreamspaces — where dreams, wormholes and content are stored. Dreamspaces must be purchased by either Gaze Coin (ERC20) or Fantasy Coin (ERC20) and then converted into a unique property ERC721 token. Dreamspace owners may either serve their own content or “rent out” the space for others to serve theirs. Owners that rent out their Dreamspace use an ERC721 ‘rent’ token and earn a simple revenue share charged on all transactions that occur within the Dreamspace.

Nexus - Past & Future

1. How did Nexus start?
Nexus started as a vision of improving the Bitcoin protocol, and at the same time cleaning the cryptosphere from scam coins.
Lead Developer Videlicet (Viz) studied the foundations of the Bitcoin Core code, understanding how Satoshi structured Bitcoin and identifying opportunities for improvement. At this time, the altcoin market was being flooded with scams and pump and dump schemes where coins pushing promises, buzz words, and the allure of quick profits were used to swindle BTC from communities. Fom Viz’s vision, Coinshield (CSD) was born.
The first CSD block was mined on September 23, 2014 at 16:20 UTC-7, and the project soon-to-be named Nexus was live. At that point, the project had one channel of mining: a Prime Mining channel (CPU). On October 23, 2014, the Hashing (GPU) channel was launched as the second proof channel. The blocks included a first-ever subsidy, where a portion from each mined block would be sent to one of 13 developer accounts and another portion would be sent to one of 13 exchange accounts. On January 24, 2015, CSD was listed on Bittrex Exchange.
Shortly afterwards, Viz drafted the first whitepaper that outlined how the network would work to recycle and merge the economies and communities of these scam coins. The goal was to help the people in those communities, bring them into the CSD community, and at the same time help clean up the cryptosphere. The exchange accounts would be used to merge these economies by exchanging the coins for a portion of CSD.
On April 11, 2015, Viz announced the intention to rebrand to Nexus. Discussion pursued about the ticker symbol, and NIRO was chosen to represent Nexus. On July 24, 2015, Nexus version 2.0 was released with Nexus Proof of State (nPOS) and the introduction of the Trust Network. This laid the foundation for the broader scope of Nexus.
At the beginning of September 2015, Videlicet revealed his identity as Colin Cantrell. In October 2015, a more formal team was formed to promote development, build the community, and market Nexus. The ticker symbol was revised to NXS. Discussions on Nexus’s direction led to the decision to abandon the recycling and merging that was part of the Coinshield project. The technical work required to implement the merging was done, but with the explosion in the number of new cryptos, the process would have had little impact. Therefore, Nexus began to develop into something much more expansive. The project had a whole new direction.
 
2. Is there a roadmap for Nexus?
Nexus does not release a detailed roadmap to the public, in order to prevent price manipulation. Providing dates and deadlines creates fear of missing out (FOMO) when they approach, and fear, uncertainty, and doubt (FUD) if they are missed or met. Instead, Nexus outlines a Strategic Vision, consistent development updates, and a set of larger releases called the TAO.
Future features:
 
3. What does TAO stand for?
Each letter represents the activation of a component required for the 3DC. Each component corresponds to a transaction level lock.
All three of these updates will include improvements to the advanced contracting virtual machine.
 
4. When is Tritium expected to be released?
The Tritium wallet will form the basis of the Tritium updates, as the new wallet will include a faster backend, and a cleaner interface design. This also speeds up transaction throughput, implements Level 1 locks, and also activates signature chains with enhanced trust algorithms.
The Nexus developers want to ensure that they release the best architecture possible and are working diligently on making this complicated process a reality.
 
5. How does Nexus solve the scaling debate?
Since every transaction requires space in a block, there are several solutions that have been proposed for blockchains. Bitcoin has Segregated Witness and Lightning Network, and Ethereum has Plasma, but both essentially rely on off-chain solutions to provide scaling (a more centralized approach). They create payment channels or side chains, that rely on the trust of the verifier to then re-commit the updated balances at the discretion of trusted verifier.
The second proposed solution is to increase block sizes or reduce blocks times as in Ethereum’s case. Effectively, this increases the capacity for new transaction either through size or frequency. Namely, more transactions can fit within a single block, or there are more blocks per time interval. Since each Bitcoin block is found roughly every 10 minutes, increased block size increases the number of transactions per second the protocol can handle.
If you look beyond these solutions, however, there is a key problem with the way the Bitcoin protocol processes transactions. Regardless of the computing power working to find blocks, each block can only fit so much data, and each block still takes 10 minutes to find. Bitcoin consumes the energy equivalent to powering a small country, and yet the only thing that increases is the mining difficulty. This is because each miner is competing with every other miner to find the next block.
Nexus recognizes that using proof-of-work as a competition is ineffective. In fact, this is the very reason that mining pools exist in the first place. Nexus’s 3D chain uses a synergistic approach where additional resources adds capability to the network. The Nexus 3D Chain by design should only be limited by node count, allowing it to scale unhindered.
 
6. What is the 3DC or 3D Chain?
Nexus’s innovation is to replace the mining pool with the blockchain itself on the Level 3 locks. Instead of miners having the authority to determine the next block by getting the winning hash, mining will become a group-wide activity. Miners will submit hashes to the network that lock the Level 2 proof of stake hashes, and agree by group consensus the data that will be locked. With no “one hash rules all,” the 3DC will be a set of hashes that will be combined into a single root hash for that block interval.
As transactions are performed, nodes in the network start verifying them immediately. When they are validated, they are locked by the CPU miners and assigned a weight (L1). This weight and trust increases as more nodes agree that the transaction has happened. As more transactions arrive, the ‘heavier’ transactions require less work and the CPU miners begin on the newer transactions.
After the transactions are validated and locked, the proof-of-stake nodes start to consolidate them into a single hash using their holdings of NXS to provide weight. This locks the transactions with the L2 Trust Lock, which is far more secure than the L1 locks, because all the information has already been verified at this stage.
The GPU miners finalize the addition of the block to the blockchain by hashing the Merkle root hash produced by the L2 Trust Locks.

7. How does Nexus solve blockchain bloat?
Every single transaction performed on a blockchain takes up a small amount of data. Over time, regardless of how small each transaction can be made, the blockchain gets bigger. This is an immutable fact of the blockchain protocol. Satoshi, the anonymous creator of Bitcoin, envisaged the network’s capacity to only be limited by Moore’s Law. As we can see now, this still is a large bottleneck.
After the Segwit upgrade for Bitcoin, a 1MB block size can fit an estimated 12195 transactions per block. With a 10-minute average time per block, that’s only about 20 transactions per second maximum. In practice, this figure lies somewhere between 7-10 transactions per second on average. In order to surpass Visa, which handles 2000 per second on average, block sizes would need to exceed 98MB. If you extrapolate this over a year, then the blockchain would grow by 5 TB every year.
Obviously, this would be difficult to sustain. There are several proposals aimed at reducing this problem, from sharding, to child chains, to blockchain pruning. Nexus’s solution uses a custom-made Lower Level Database to select nodes to service pieces of the 3D blockchain structure. This allows nodes to partition their data use and chain storage across the network. They will no longer require the full chain to reside on their system. The more nodes in the network, the less each individual node will need to service.
 
8. Will Nexus incorporate smart contracts?
Nexus’s contract functionality will consist of contract templates embedded into the underlying code within the 3DC. Nexus contracts will not be turing-complete because infinite runtime is never necessary nor secure in a digital currency. This means Nexus contracts will be more usable without creating network congestion issues.
Some of these contracts will be used to enable key Nexus functionality and will work invisibly. Examples of this functionality includes:
Contracts can be used to store and update information, create payment channels, prove identity, and any number of possible functions yet to be imagined.
 
9. Will there be any hard forks in Nexus?
Nexus is designed to avoid hard forks via the incorporation of an update mechanism which will create updates to consensus rules without having to change the code. These rules will only be issued by developers and their according developer key signature, and will be validated by the other five voting groups.
 

Bringing Nexus to Earth:

1. Nexus claims to “decentralize the decentralization.” What does this mean?
As decentralized as blockchain technology strives to be, it nevertheless remains dependant on traditional infrastructure. By combining the decentralized blockchain software, satellite and ground based mesh networks, and a large team of passionate people, Nexus is focused on gaining a high degree of autonomy from external influences. By placing our own communication infrastructure in space, the network won’t be susceptible to government jurisdiction (similar to international waters).
Nexus’s three-dimensional chain will also reduce the need for mining pools. Pools exist because traditional blockchains only reward miners when they find a block, which can be rare. In essence, Nexus will become the pool, with miners being rewarded for each contribution instead of each block.
The phrase “decentralize the decentralization" was taken from an article written by founder Videlicet on May 6th, 2016. It was the introduction to the idea of “Blockchain 3.0”, and followed up with the technical architectures outlined above. The full article can be read here.
 
2. How is Nexus going to put cubesats into orbit?
Nexus has partnered with Vector Space Systems, which was co-founded by Jim Cantrell. Jim is a veteran in the aerospace industry, having worked with NASA and co-founding SpaceX with Elon Musk. Vector uses small disposable rockets to cut down costs, and are capable of launching 66 kg into low earth orbit (LEO). A standard 1U cubesat weighs less than 1.33 kg, so each launch can put approximately 25 satellites into orbit. We have also found certain opportunities in developing satellites that weigh less than one kilogram to increase the number of satellites per rocket launch.
 
3. Why is Nexus using Vector Space and Galactic Sky?
Vector Space offers affordable launch capability, as it seeks to reshape the multi-billion dollar launch market. It is an innovative leader in the micro-satellite launch industry, as big companies like SpaceX focus on launching mid- to large-size satellites into geosynchronous orbit. Vector plans to be one of the first companies to offer affordable low earth orbit (LEO) capability in 2018.
Galactic Sky, which is a business unit of Vector, uses software-defined satellites to provide a satellite virtualization platform. Using this virtual environment, developers can test ideas and algorithms to demonstrate satellite viability without having to launch and test in orbit. This helps accelerate the conception and testing process, going from years to weeks.
The connection between Vector Space and Nexus goes beyond that of supplier and client. Jim Cantrell, CEO and co-founder of Vector Space Systems, is a firm supporter of Nexus and has interest in its success.
 
4. When will the first cubesats be launched?
Nexus is planning to start launching its first satellites for the Phase 1 constellation in 2019. The satellite designs are currently in development, with our top priority being the implementation of the TAO framework supporting the 3D blockchain. We will also see collaboration with Galactic Sky as it is deployed through the year of 2019.
 
5. How many cubesats are required for the mesh network?
The Nexus mesh network will consist of a range of satellites, from the sub-1U to the larger 3U satellites. Approximately 2000 cubesats will be required to achieve total global coverage. The ground-based mesh networks will help scale and balance this load by performing data transmission on the ground rather than requiring satellite access at all times.
Constellations will be put up in stages, with Phase 1 providing intermittent connectivity. Our launch agreement terms will be disclosed as it is formalized in early 2018.
 
6. How much does it cost to build and deploy the satellites, and how is this funded?
Each 1U cubesat costs approximately $20,000 - 50,000 each to produce depending on assembly and how many units are purchased. A 3U satellite, being larger, can cost up to $100,000. Each Vector launch costs between $1.5 million and $3 million, depending on payload size.
The funding for building and launching these satellites will come from the Nexus Ambassador Fund.
 
7. Does Nexus have any developers working on developing the mesh network?
The mesh network is being developed by Phillip Swazey. Phillip used to work for Iridium, a satellite communication company which currently operates its own satellite constellation. He is currently designing our preliminary 1U satellites for Phase 1 deployment.
