I would like to gift some mBTC to all my nephews this Christmas. I plan on making a bunch of paper wallets for all of them, and hopefully it will grow into a nice stash by the time they spend it.
Do someone have a good paper wallet design? With folding for hiding the private key and instruction about bitcoin, how to protect it and how to spend it. What's the most secure offline generator?

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.

Bitcoin gift idea for no coiners

Just thought I’d share a neat concept I used to gift bitcoin to friends/family members on their birthday or Christmas which was received rather well and generated a lot of interest. Use a mockup certificate to create a “bitcoin gift card” which displays the amount you are gifting (in bitcoin, since the value fluctuates) to the name of the person. You can add other elements like the coin name (Bitcoin of course, but I’ve done it for Litecoin also since a family member already had BTC), add the coin symbol etc to make it look more quirky. Add a QR code that links to a reliable source that explains how the gift holder can create a wallet of their choice without being mislead. Once the gift holder acknowledges that they are ready to receive their token, you ask for their address and send over a test transaction to confirm that they’re doing it right. Then send over their gift funds. Interest sparked. Creative gift idea compete. If they don’t create a wallet you simply hold their funds on their behalf until they are ready to receive / might even want to cash out instead - of course you insist that they don’t cash out and explain the HODL wisdom.
Edit: Once you’ve mocked up the certificate I’d personally use a professional print company that offers documents to post. Printing the certificates yourself would just result in a unpro piece of paper which doesn’t look official or legit. Those certificate mockups I linked above look so sweet and the quality is amazing when printed on thick shiny paper.
I used this method two/three years ago for my mother and she literally framed the certificate and was so chuffed that she owned Bitcoin. To this day, she hasn’t cashed out and always checks the price, bless her.
Edit: Wow thanks for the silver mystery reddit user, never received any awards before so that was a super nice surprise! I will continue to find new ways in which to expand bitcoin into the mainstream. God bless Bitcoin and the community!

Beginner's Guide: Where to start & FAQ!

New Flair Rule

We've been overwhelmed with newcomer posts. In light of this, we created a bot that will PM people without flairs various pertinent information to read through when they post. In order to stop receiving these, simply add a flair to your name. Thanks!

Scam Warning

Hey guys. There have been numerous scammers lately who have been private messaging redditors. Their goal is for you to send Litecoins to their address. So far, they've followed the same writing template. It looks something like this: https://imgur.com/0UZczuz
If someone is telling you to send to a Litecoin address they are providing, DON'T. They're trying to steal your Litecoins. If you're not sure, read the wealth of knowledge below or comment below and I will eventually get to you.

Welcome to /Litecoin!

(Re-post of u/Sparkswont cuz it was archived)
Whether you're new to cryptocurrency and have no clue what a 'litecoin' is, or a seasoned investor in cryptocurrencies, the resources below will answer all your questions. If you still have questions, feel free to ask below in the comments!
 

What is Litecoin?

Litecoin (LTC or Ł) is a peer-to-peer cryptocurrency and open source software project released under the MIT/X11 license. Litecoin is one of the largest, oldest, and most used cryptocurrencies in the world. Similar to Bitcoin, Litecoin uses blockchain technology to process transactions.
So what's the difference? To process a block, Litecoin takes 2.5 minutes rather than Bitcoins 10 minutes. This allows for faster processing times. Litecoin also has the capability to produce a total of 84 million units, compared to Bitcoins 21 million. In addition, Litecoin uses scrypt in its proof-of-work algorithm, a sequential memory-hard function requiring asymptotically more memory than an algorithm which is not memory-hard.
Still confused? Take a look at this video!
 

Where can I buy Litecoin?

There are many websites and applications where you can buy and sell Litecoin, but make sure the exchange you are using is trusted and secure. Here are some exchanges that are trusted in the cryptocurrency community:
Exchange
Coinbase USD/Euro/GBP
Quadrigacx CAD
Coinsquare CAD
Bithump KRW
OKCoin Euro/Yen/USD
OKex CNY
Btcmarkets.net AUD
Bitso MXN
Zebpay INR
 

Where can I securely store Litecoin?

Litecoin (and other cryptocurrencies) is stored in a digital wallet. When storing Litecoin, you want to make sure you trust the place you store them. This is why it is best to store them yourself through the electrum wallet. It is highly suggested to not store your Litecoin in an exchange (such as Coinbase, Poloniex, Bittrex, etc.) because you don't control the private keys. If the exchange ever goes offline, or becomes insolvent, your Litecoin essentially disappear.
Some other options are:
Wallet
Electrum Lightweight Wallet
Official Core Wallet
LiteVault Secure Web Wallet
Paper Wallet Instructions
 
If you're a fan of mobile devices, then Loafwallet is the wallet for you. Developed by a Litecoin Foundation Dev, losh11, this mobile wallet works great! And remember to always make sure to write down your seedkeys.
 
Hardware wallets are another great option, in fact, they are said to be the most secure way to store cryptocurrencies. Below is a list of the litecoin flexible hardware wallets.
Wallet
Ledger
Trezor
Keepkey
 

Where can I spend Litecoin?

Litecoin is in the top ten of all cryptocurrencies by market capitalization. Websites are rapidly adopting Litecoin as a method of payment as well. If you yourself want to accept LTC as a business, you can refer to these merchant manuals. Alternatively, if you would like to explore websites that accept Litecoin, head over to /AcceptingLTC.
Here are also several of our favorite merchants accepting Litecoin.
 

Where can I discuss Litecoin?

The Litecoin community is extremely kind and robust. There are many forums and places where you can discuss Litecoin with others who are interested in the currency. Here are the main ones:
Platform
Reddit
Litecoin Markets Subreddit
Discord
Official Forum
IRC
 

Additional Resources and Help

If you have more questions, or are genuinely interested in learning more about Litecoin then be sure to read this series. If you have a specific question that you can't seem to find the answer too, ask below and someone will help you out!

Don't forget to bring Paper Wallets to the Oktoberfest for tipping the waitresses

Don't forget to bring Paper Wallets to the Oktoberfest for tipping the waitresses

Every year the Oktoberfest brings over 6 million people from all around the world to Munich. Which place would be better suited for a little adoption work?
Because there is no way you can pay directly with Bitcoin Cash, we want to focus instead on the waitresses because you can always tip them via a Paper Wallet.
We have created a template in German that explains to the waitress how they can redeem a Bitcoin Cash Paper Wallet. All you have to do is to replace the QR-code with the one for the private key that you want to use for the tip and print it out.

[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.

Tutorial: How to receive Bitcoin donations on your Street Art works. This tutorial explains in 3 steps how to receive Bitcoin donations on your street art works:

Tutorial: How to receive Bitcoin donations on your Street Art works. This tutorial explains in 3 steps how to receive Bitcoin donations on your street art works:


Step 1 — Creating a Bitcoin Portfolio
First, it is necessary to create your wallet , which will generate your reception address (the equivalent of a bank account that belongs to you).
Thanks to this receiving address, you will be able to receive transactions in your wallet.
The Coinomiwallet is one of the easiest to use , available on Android, iOS, Windows, MacOS and Linux.
You are free to use any other wallet: Samurai Wallet , Spot , Electrum … Make sure that the wallet you choose is recognized and trusted because hacks , phishing and scams are commonplace in the world cryptocurrencies.
Download the application .

Once installed, click on “Create new wallet”.

The wallet will generate you your recovery phrase (or “Seed”, which is the private key of your wallet) which is most often a suite of 24 words.

Write down your recovery phrase by hand on a sheet of paper and keep it in a safe place (be careful to keep it private, anyone who owns this sentence becomes the owner of your funds).


Confirm to the wallet that you have correctly noted the recovery phrase and choose a password .
2nd step — Create your QR code visual
From your wallet, you need to generate your QR code of the receiving address .
Go to “Bitcoin BTC” in the wallet.

Click “Receive” (if indicated, choose a reception address “Compatibility” rather than “Default” or “Legacy”).


Bitcoin receive address example1F4bwjr74bmcXwRu53Jh27JRRCWHHd4yrz
You can now retrieve the QR code with a screenshot and save the receiving address .
To put this QR code on your works, there are 2 methods; a very simple and accessible to all (printing on paper and collage) and the second is a little more complicated (cutting stencil) but more durable:
  • The easiest way is to print the QR code on paper with the mention “Bitcoin donations” at the top and your Bitcoin receipt address at the bottom and paste it into your work.

Download this template and add your QR code and receiving address (as above). Check that the address shown corresponds to the QR code by scanning it with a smartphone.
Optional: It is recommended to add your website (or social networks) to allow people to validate that this is your Bitcoin address (and not that of a person posing as you). Of course, this same Bitcoin receiving address must appear on the front page of your site (and in your social networks profile) to allow donors to verify that the funds will be received by you.
Once the sheet is printed, you can paste it on your next street artwork. Prefer flat and smooth surfaces for better adhesion of the poster. We must make sure that it fits in with the signature of the work so that we understand that the gifts are for you.


- The second method is to create a QR code stencil and use a spray bomb to put it in your work.
There are 2 possible cutting techniques: A manual technique that requires some basic DIY. The second technique is to prepare the visual Photoshop and Illustator then to call a provider who will cut the stencil for you.
1st technique — Manual: To make yourself the stencil, you will need a rigid sheet, a cutting support, a cutting scalpel, Masking Tape, a black felt pen, a clamp and a thin square grid.
To make the QR code stencil by hand, see this tutorial .


Once the stencil of QR code is made, make a stencil with the mention “Donate Bitcoin” and add it to the first stencil to understand that this is your Bitcoin reception address. You can write it yourself or use this template (below) that you can print and overlay your rigid sheet.


Once your stencil is ready (“Donate Bitcoin” + QR code), you can put it on your next work with a black paint spray. Prefer flat, smooth and clear surfaces for a better readability of the QR code. We must make sure that the stencil is integrated into the signature of the work to understand that the gifts are for you.
2nd technique — Stencil cutting by a provider: To create a QR code stencil, it is imperative that all the background of the visual is connected to allow cutting of the stencil, for this, it is necessary to go to a site that generates QR compatible stencil code like qrcode-zebra.com


Once on the site, choose the “Text” tab and paste your Bitcoin receipt address and click on “Generate QR code”. Your QR code will appear, but the design will not be the right one. There are a few changes to make. In the “Choose patterns” tab on the left, click on the first pattern (which looks like a square grid), then in “Choose eyes”, click on the first box (the basic square “eyes”). Then, in “Set colors”, choose the color black.
Optional: if you wish to add your logo or signature, you can add it in “Add logo”. The file should be as simple as possible, in black with transparent background that connects (compatible with a stencil cut).
Now that the QR code is ready, you can retrieve it with a screenshot or click on “Dowload PNG” and give your email address to receive the QR code as a PNG file.
Then, on Photoshop, it is necessary to couple the grid of your QR code with this model so that the mention “Donations in Bitcoin” and the 3 “Eyes” square of the QR are compatible for a stencil cut. Use overlapping layers and erase old “eyes”.


Finally, download this special stencil typography and use it to enter your Bitcoin receipt address used on your QR code. Check that the address shown corresponds to the QR code by scanning it with a smartphone.
It is strongly recommended to also add your website (or social networks) to allow people to validate that this is your Bitcoin address (and not that of a person posing as you). Of course, this same Bitcoin receiving address must appear on the front page of your site (and in your social networks profile) to allow donors to verify that the funds will be received by you.
Once the visual is ready and fully compatible for stencil cutting, you can vectorize it in Illustrator and save it in EPS or AI format.
Last step, send this file to a provider who makes stencil cutting.
It’s up to you to choose the provider that best suits your location, price and time. Choose a format that suits your job. For large frescoes, larger formats (A2) are preferable, and for smaller works, smaller sizes (A4).

Once you receive the stencil, you can affix it to your next work with a black paint spray. Prefer flat, smooth and clear surfaces for a better readability of the QR code. We must make sure that it fits in with the signature of the work so that we understand that the gifts are for you.


3 — Last step, communicate.
Let all those who follow your work know that they can now support you financially by sending you Bitcoin donations on your Street Art works. You can use the means you have available, your contacts, your website, your social networks …
To help beginners, here is a tutorial that explains how to buy Bitcoin.
To track the transactions you receive, you can open your wallet regularly to see your balance.
To receive a notification when you receive a donation, you can use your Wallet to track transactions at an address of your choice.
The public can also see your balance received on your address thanks to blockchain explorers.
Here is the balance of a donation address: 3Pboy9ucGEdQUHNu2rrC6RGq4jouRc4Grb
If you receive a lot of donations, it is a good opportunity to communicate on the amount received.
Good luck and good creation!
FAQ
Why use Bitcoin?
The money you receive is 100% in your possession because you are the sole owner of your private key (recovery phrase, or “Seed”), unlike other centralized means of payment (Banks, Paypal, Ulule, Patreon. ..), Bitcoin happens totally of intermediary of confidence.
How do I use Bitcoin?
Thanks to your wallet you create a private key and a public address. The private key (recovery phrase, or “Seed”) is a bit like the key to your digital vault that you need to keep only for yourself. The public address is your RIB to receive transactions, you can share it publicly without problem.
How do I exchange my bitcoins for USD?
You can at any time send your bitcoins on an exchange online ( Coinbase …) to convert them into currency (Euro, Dollar …). You need to create an account on one of these exchange exchanges, convert your funds into the desired currency and then make a transfer to your bank account.
A faster solution may be to use a centralized service provider that offers a Bitcoin wallet connected to a credit card to spend your bitcoins directly ( Wirex , Coinbase …).

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 a 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 sued "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. Verify download with gpg --verify pypaperwallet.tar.gz.sig
  5. Extract the contents of the .zip or .tar.gz file to any directory
  6. From Python 3.7 run pip install pypaperwallet.tar.gz to install dependencies
  7. Review the README.md on how to install the GTK cairo dependency
  8. Modify test.py to your liking and run from python 3.7 to produce the PDFs.
  9. 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.

CSW: I am Satoshi Nakamoto. I created Bitcoin - [BitKan 1v1] Craig Wright vs Jiangzhuoer

https://preview.redd.it/csnm617kv8d31.png?width=1058&format=png&auto=webp&s=26b7995effc85781365cbcd2ad56c5bd33c59af5
Question 1: Both the BCH and BSV communities think that they are the true, original bitcoin from Nakamoto. What do you think was the original idea from Nakamoto?
**CSW:**My original idea is defined in white paper for no limits. And I also described this in the P2P Foundation. It is a distributed system. Users use it to connect to each other, and the miners, to stop double Spending. I explain this further late in 2010, I basically said that the network expands to have a number of nodes that become large data center type operations, because it's not about running nodes. People who run nodes are foolish unless that making money, that's it. When I created Bitcoin, it is a overlay network of the peer-to-peer network, the top of peer-to-peer network. We did peer-to-peer. Peer-to-peer means not what you send to the network, and then another user gets it by the network. That is outside the definition of peer to peer. That is a typical centralized mesh. Why Bitcoin works is that user Alice sends to user Bob,Bob received the transaction. So Bob wrote that he received it. He sent it to the network. IP to IP was one of the fundamental parts of Bitcoin that was removed by core right after I left, basically, I fix Bitcoin and I had the lay out in the first place. There's no question that what happened, and whatever else and what version of things Nakamoto wanted, because I am Satoshi Nakamoto. I created Bitcoin. Very soon, people will notice that. If you don't like it, I don't care.

Question 2. As the main witnesses of BTC to BCH fork, what do you think was the main reason for the fork at that point of time? Now what do you think about the fork at the time? Have you ever changed your mind?
CSW: There was a BCH fork away from Bitcoin, BTC added a number of things to make cryptocurrency more anonymous, which makes it illegal, which means the government can shut it down. Don’t ever believe the government can’t stop bitcoin. Government, the US government and Chinese government could stop bitcoin in a heartbeat. They are going to follow international law to shut down. The Liberty Reserve closed down involved 42 countries working together. It involved basically a distributive system of 10,000 different operations. Not Raspberry pie nodes because it is only 15 real BTC nodes, operators to ran money system. We can't work to unable governments to see machines. If the criminal use of bitcoin is to become anonymous that government can seize machines, can arrest people, can torture by law. The American government can enforce orders in China. So BTC wanted to make something that was not bitcoin. It wanted to change bitcoin further. So BTC split away from bitcoin. That's the fork. Bitcoin didn't change. I make sure we kept going. Jihan and Bitmain. I would like to have a talk about what we are planning, and the mining, we are building. Jihan and Bitmain, took the information to go into confidence and make sure that there was a fork. So this fork happened because Jihan and Bitmain are basically a bunch of lying stuff, and that would be found out later. The second fork was only last year. That was with BCH. Just to keep it simple. Bitcoin vary again. There’s no system of bitcoin is out to try to make it illegal, to make it criminal, to make it anonymous. Roger Ver, who helps from things like Silk Road and Charlie's friend money laundering operation, which Charlie's friend went to jail for. Other people like them that invested a lot of the dark websites, which all under investigation at the moment, which will be founded to watch in the next several years. People like Roger and even Jihan, wanted to use bitcoin to take the illegal money and transfer, they want it to be a dark web system. So they added extra objects to change the bitcoin further. They try to allow it to be more anonymous in a different way. So the simple thing is, there is bitcoin as I created, and there is bitcoin designed to be illegal and then it forks.

Question 3. Finally, can we invite Dr. Craig and Mr. Jiang to talk about each other's technology l and vision? What is the most worthwhile point to learn?
**CSW:**Sorry, I don’t look at those broken versions of bitcoin. I have no interest in learning about how people don’t want to understand bitcoin, how about you want to see the value and how they want to create the system or see these cryptocurrencies in the 90s. If people want to do that, that’s all their choice, but I am not interested in watching them go down in flames. Thank you.

Jiang asked CSW: You have ever wondered why there isn't a 0 in Base58 encodings. (Satoshi, the creator of Base58 explicitly took out 0 and O to avoid confusion). Why didn't you even know the Base58 encoding if you are Satoshi?
https://www.reddit.com/btc/comments/9apx40/professor_technobabble_wondering_why_there_isnt_a/
CSW: He's supposedly trying to mislead the audience by making out the checksum to pass off the transaction. He is basically trying to lie to the people and the audience, making them seen that I don’t understand bitcoin. If you look at why it works, the address was not part of the bitcoin. Bitcoin is a wallet, exchange peer-to-peer with the template. Basically, why does this work is that you have is a transaction that has a checksum to send between wallets. That checksum is a relevant. It never goes into the bitcoin network. The checksum is added only to ensure the transaction to the network while a wallet is correct. The original version of bitcoin didn’t eventually work that way. So what he is trying to mislead you is to say is what I don’t understand checksum etc., which is the lie propagate by people like Bitmain, where insists what it is you do a checksum of the code and then you hand it up. And the third part of this is very simply put. Without the checksum, the transaction sends to the network properly. The checksum is purely a wallet function, so you can add any checksum function and Wormhole would allow this work. Wormhole was an attempt to make an illegal system. Wormhole is another of these things because Jihan and the others wanted to take money out of China. They work with people to do money laundering, so the value that they see of bitcoin is to help money laundering. So they want to try and lie to people and make it that I don’t understand this technology, because they want to keep their money laundering scam going. So if you actually look at my posts, you will see that I've already explained the checksum in details. If you look at the work bitcoin transaction, you will see there has no transaction checksum. No one wants you to look at that because they want you to stay stupid and ignorant, because spending money out of you requires that you are dumb.

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 :)

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.

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).

[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.

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?
