Getting your Private Keys from the Bitcoin Core wallet
 
05:11
In this tutorial we are going to get our private keys from the bitcoin core wallet. This only works when you created the bitcoin address in the same wallet. Because only when you create a new address you create a new private key that will be stored encrypted in your wallet.dat (your private key database)

What is a private key? How are they generated and formatted? Are private keys transmitted when you make a transaction? What are the chances of collision? Will quantum computing making it easy to guess private keys? Does implementing quantum-proof algorithms require an overhaul of the code?

What Is A Bitcoin Wallet? - The Best Explanation EVER
 
04:06
This is a free sample lesson from 'The Secrets Of The Bitcoin Triangle' course, where you will 'Discover The 21 Fast Track Ways To Make And Save With Bitcoin (Starting From Scratch)'. You can sign up for the full course at: https://cryptoversity.krtra.com/t/r54RTiOWLIZa A Bitcoin wallet is a piece of software you use to communicate with the Bitcoin network and tell it when you want to send and receive transactions. The best way to understand a Bitcoin wallet is by comparing it to email. Once you have setup an email address you need some kind of software to allow you to send and receive emails to that address. Now this software may be an app on your phone, it may be an app on your laptop or it could even be an app you log into online. With email, you enter the username and password for your email address into the app and that’s how the Internet knows it’s really you that is sending and receive emails to that address. Now of course you tell everyone your email address and you have to do that in order for anyone to send you a message. But just because someone knows your email address, that doesn’t allow them to send email from that address. If they could that would be bad because then they could send emails pretending to be you and cause all kinds of problems. In order to be allowed to send email from a particular email address, you have to know the password. If someone finds out your email password then there’s nothing stopping them from logging in to your email app and sending messages. This is very similar to how a Bitcoin wallet works. Every Bitcoin account has two elements to it. One is called your public address, which is like your email address, and one is called your private key, which is like your password. So just like email, you can give anyone your Bitcoin public address and then anyone, anywhere in the world can send you some Bitcoin. They don’t need to know anything about you. All they need is that public address and they can send money to you. Your Bitcoin private key on the other hand is the one thing you must protect. It’s called your private key for a reason because you should never reveal this to anyone. If someone gets your email password, that’s bad because they can start sending emails from your address, but that’s not quite as bad as someone getting your Bitcoin private key because then they can steal all of your Bitcoins by sending them somewhere else. And just like email, once a Bitcoin transaction has been sent, it’s a one way trip. The only way to get it back would be for the person you sent it to to voluntarily send it back. Bitcoin literally works like digital cash. Once you’ve handed it over, the Bitcoin belongs to that other person. And the same goes for when you receive Bitcoin. Once someone sends it to you, it’s yours and no one can take it from you. The only way they could do that is if they knew your private key. And of course now you know never to give this to anyone.

What is BITCOIN CORE? What does BITCOIN CORE mean? BITCOIN CORE meaning, definition & explanation

What is BITCOIN CORE? What does BITCOIN CORE mean? BITCOIN CORE meaning - BITCOIN CORE definition - BITCOIN CORE explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ Bitcoin Core is a reference client of bitcoin. Initially, the software was published by Satoshi Nakamoto under the name Bitcoin, then Bitcoin-Qt and later renamed to Bitcoin Core. It is also known as the Satoshi client. It is a full client used by bitcoin nodes that create the bitcoin network. Through the changes to Bitcoin Core, its developers make changes to the underlying bitcoin protocol. As of 2017, Bitcoin Core repositories are maintained by Wladimir J. van der Laan. The MIT Digital Currency Initiative funds some of development of Bitcoin Core. The project also maintains the cryptography library libsecp256k1 and others located at GitHub. In August 2016, a warning was issued regarding the software being targeted by state-sponsored attackers. The Bitcoin Foundation also warns that running the software may attract attacks which limit available download bandwidth. It includes a transaction verification engine and connects to the bitcoin network as a full node. Moreover, a wallet, which can be used to transfer funds, is included by default. The wallet allows for the sending and receiving of bitcoins. It does not facilitate the buying or selling of bitcoin. It allows users to generate QR codes to receive payment. The software validates the entire blockchain, which includes all bitcoin transactions ever. This distributed ledger which has reached more than 110 gigabytes in size must be downloaded or synchronised before full participation of the client may occur. A command line-based daemon with a JSON-RPC interface, bitcoind, is bundled with Bitcoin Core. It provides access to testnet, a global testing environment that imitates the bitcoin main network or Mainnet. It uses an alternative blockchain where real bitcoin are not used and the blockchain cannot be adversely affected. Regtest or Regression Test Mode creates a private blockchain which is used as a local testing environment. bitcoin-cli is the third program included. It allows users to send RPC commands to bitcoind. Checkpoints have been hard coded into the client. These maintain data integrity by keeping a part of the block chain data in the source code where it is able to be compared to the blockchain when its downloading is complete. A one megabyte block size limit was added in 2010 by Satoshi Nakamoto as a temporary anti-spam measure. This limited the maximum network capacity to about three transactions per second. Since then, some minor changes to the software have improved network capacity incrementally. A network alert system was included by Satoshi Nakamoto as a way of informing users of important news regarding bitcoin. In November 2016 it was retired. It had become obsolete as news on bitcoin is now widely disseminated. Miners are able to signal their decision on the incorporation of new features by voting. A powerful scripting language is used to define transactions. This Forth-like language is part of one of three distinct application programming interfaces. It can enable various transaction parameters. The script uses reverse Polish notation for validation. ScriptPubKey is used to "lock" transactions based on a set of future conditions. scriptSig is used to meet these conditions or "unlock" a transaction. Operations on the data are performed by various OP_Codes. Two stacks are used - main and alt. Looping is forbidden. ....

Get your private key from your 24 word recovery phrase without Ledger Nano
 
04:20
How can you recover your Ledger Wallet without a Ledger Nano S? You use this procedure at your own risk! Overview of this video 1.Bitcoin a. Restore public address and private key for Bitcoin b. Check the address and private key and print optionally a paper wallet 2. Ethereum a. Restore public address and private key for Ethereum b. Check the address and private key You can recover your keys without a Ledger Nano S This video shows how you get the public and private key of Bitcoin and Ethereum from your leder 24 words recovery phrase. My recovery phrase: This is only for testing. I don't use this seed. gold wagon iron scatter asset glare boy valley fit pony end volume soup shed elder brown museum gas blanket icon strong ill face dice Buy the Ledger Nano S: https://www.ledgerwallet.com/r/9054 Tools from Github: https://github.com/Coinomi/bip39 https://github.com/iancoleman/bip39 https://github.com/cantonbecker/bitcoinpaperwallet Update 14.10.17: I have observed the following on BTC. Probably the same for Ethereum: The ledger nano s is using multiple receiving addresses. This means each time something is transferred to your new public address; a new receiving address is shown on the ledger wallet. You can use the old or new one. In my example phrases for BTC I have the following public addresses: Path Address m/44'/0'/0'/0/0 1L4w71doDD9JVS8LrTBAyYCsn2rjeSXr3c m/44'/0'/0'/0/1 1NRyjtSdHdJxUXa6zNjnD8mC718sMhHJYh m/44'/0'/0'/0/2 14mFMXqE4TGnGpgt36fzR9pCYPGA12bj4d m/44'/0'/0'/0/3 12qeFoQkkssWt497Pk9GYiuDfLoLx9eNzi etc. If you have an empty wallet and you haven’t used the receive address, the ledger wallet shows the address of path m/44/*/0. If you transfer the first amount to this address, the next time you click on your receiving address in the ledger wallet is shown the address for path m/44/*/1. If you transfer now something to path m/44/*/0 , the shown public receiving address keeps at m/44/*/1. Next time you send something on path m/44/*/1, the receiving address is updated again. And so on. The wallet shows the sum of all your receiving addresses. Be aware of this behavior in case that you use different receiving address, that you remember either the phrases or all of your private addresses of the used paths. I hope this is useful. Update Bitcoin Gold: If you have your bitcoins on your ledger wallet before the 25th of October then everything is fine. You will also get this amount in BTG. If you want transfer BTG immediately after the hard fork and in case that the ledger nano SW is not ready for BTG. You can use your private key together with the Bitcoin Gold adaption of the bitcoin-core app. Be careful on Bitcoin Gold transfers. BTG has no strong replay protection. Please inform you, how you can avoid such replay attacks to your transfers. Update 21.11.17: segwit addresse bitcoin Use https://github.com/iancoleman/bip39 Insert your 24 Words, then Coin select BTC – Bitcoin. Go to the Tab BIP49 and you can see the segwit addresses. I have tested this with my ledger. In the example above with: “gold wagon iron scatter asset glare boy valley fit pony end volume soup shed elder brown museum gas blanket icon strong ill face dice” The result is Segwit Address Private Key m/49'/0'/0'/0/0 37Qn9ar9Ye5B69u7hS71A8aiQyXWXamhLu Ky3a7b... m/49'/0'/0'/0/1 3MEK1Fr5y5mri2ZLDGm3w4tTpunhqtBuc1 L4sxdG... m/49'/0'/0'/0/2 3QLsakUYqFP44JwesY8HRGpEgTdn21jsWm L3PJCg...

How to Download & Verify the Bitcoin Core Wallet

Bitcoin is a new technology that functions as a digital currency. It is a peer-based, decentralized way to hold, store, send, and receive value. It does this by maintaining a cryptographic “ledger” called the Blockchain. All of the bitcoins in existence are created and stored on the Blockchain. Bitcoin with a capital “B” refers to the technology itself. Bitcoin spelled with a little “b” refers to the tokens that hold the value and can be exchanged with others. Multiple copies of the Blockchain exist on thousands if not millions of computers worldwide. Each copy of the Blockchain “verifies” itself by connecting to the Internet and making sure it has the most up-to-date list of transactions. The Blockchain maintains its integrity by using strong, modern, encryption techniques. This makes it impossible for anyone to alter the ledger, create fake transaction or “double-spend” their bitcoins. Bitcoins do not require banks or third-party financial services to act as central clearing houses for electronic transfers. In essence, Bitcoin technology “cuts out the middleman”. Bitcoin is a decentralized, peer-to-peer monetary system that exists outside of the traditional, centralized, fiat-currency based financial system. Is Bitcoin money? Good question! The short answer is yes! But the long answer requires that we talk a little about what “money” is or what it should be. Money is basically an idea. It is a system that we can all agree upon which allows us to exchange value, so we do not have to carry around cows or chickens with us to trade for the things we need. An ideal money or “currency” should have the following properties: Portable Fungible (interchangeability) Dividable Durable Cognizable (easily identified) Stable Does Bitcoin fit the bill? Well it’s certainly portable. It is all digital. It weighs nothing (unlike gold which can be heavy and bulky in large amounts. For that matter, traditional paper currencies can also become heavy and bulky in large amounts!). It can be sent across the room or around the world with the same ease and comfort. You can carry it on a piece of paper, a laptop, or even your smart phone. It is Fungible. Every bitcoin is like every other bitcoin (unlike shells, beads, and traditional precious metal coins which can be “shaved” or diluted in purity) It is dividable. It is actually one of the most dividable currencies ever conceived! It is possible to spend small fractions of bitcoins and no need exists to make change. When was the last time you were able to spend 1/8 of a penny? Bitcoin is durable. It is protected by strong encryption and the Blockchain exists in thousands if not millions of locations simultaneously. You would literally have to delete the blockchain from every computer and smart phone in the world to destroy a bitcoin. Bitcoin is cognizable or easily recognized. It’s based on math. No one can dispute a number or deny that 1 + 1 =2. People are just beginning to understand what Bitcoin is. There is a bit of a learning curve. But once you are familiar with it, you will know it when you see it. Is Bitcoin stable? Well the current value of a bitcoin has been quite volatile lately in relation to other traditional currencies. But the Bitcoin plan calls for the creation of only 21 million bitcoins. In this way, Bitcoin will try to avoid the pitfalls of modern fiat currencies such as inflation, deflation, market manipulation, monetary policy, quantitative easing, and other central manipulations that effect the day-to-day value of the money we use.

What is a Bitcoin Address?
 
04:27
http://www.bitcoinreport.info - What is a Bitcoin Address? While a Bitcoin address works in a similar way to a bank account number, it is much more than that. The best way to answer the question "what is a Bitcoin address?" is to define it as a Bitcoin wallet identifier, of which there can be many. Unlike a bank account number, a Bitcoin wallet can generate an unlimited number of Bitcoin addresses, which can be used to identify incoming funds from regular payers, or even as a way of enhancing your privacy. Obviously to have a Bitcoin address you first need a Bitcoin wallet, and if you check my videos here you will see that I have put up one on the subject of choosing such a wallet. https://www.youtube.com/watch?v=lUZQ7RxR3rU

Bitcoin Q&A: Full node and home network security
 
10:47
Does running a Bitcoin and Lightning node at home attract hackers? Why is security through obscurity not the best strategy? What is some general advice on securing your personal computer and home network? Are there full node starter kits? Could bitcoin nodes be cut off if ISPs blocked port 8333?

Symmetric Key and Public Key Encryption
 
06:45
Modern day encryption is performed in two different ways. Check out http://YouTube.com/ITFreeTraining or http://itfreetraining.com for more of our always free training videos. Using the same key or using a pair of keys called the public and private keys. This video looks at how these systems work and how they can be used together to perform encryption. Download the PDF handout http://itfreetraining.com/Handouts/Ce... Encryption Types Encryption is the process of scrambling data so it cannot be read without a decryption key. Encryption prevents data being read by a 3rd party if it is intercepted by a 3rd party. The two encryption methods that are used today are symmetric and public key encryption. Symmetric Key Symmetric key encryption uses the same key to encrypt data as decrypt data. This is generally quite fast when compared with public key encryption. In order to protect the data, the key needs to be secured. If a 3rd party was able to gain access to the key, they could decrypt any data that was encrypt with that data. For this reason, a secure channel is required to transfer the key if you need to transfer data between two points. For example, if you encrypted data on a CD and mail it to another party, the key must also be transferred to the second party so that they can decrypt the data. This is often done using e-mail or the telephone. In a lot of cases, sending the data using one method and the key using another method is enough to protect the data as an attacker would need to get both in order to decrypt the data. Public Key Encryption This method of encryption uses two keys. One key is used to encrypt data and the other key is used to decrypt data. The advantage of this is that the public key can be downloaded by anyone. Anyone with the public key can encrypt data that can only be decrypted using a private key. This means the public key does not need to be secured. The private key does need to be keep in a safe place. The advantage of using such a system is the private key is not required by the other party to perform encryption. Since the private key does not need to be transferred to the second party there is no risk of the private key being intercepted by a 3rd party. Public Key encryption is slower when compared with symmetric key so it is not always suitable for every application. The math used is complex but to put it simply it uses the modulus or remainder operator. For example, if you wanted to solve X mod 5 = 2, the possible solutions would be 2, 7, 12 and so on. The private key provides additional information which allows the problem to be solved easily. The math is more complex and uses much larger numbers than this but basically public and private key encryption rely on the modulus operator to work. Combing The Two There are two reasons you want to combine the two. The first is that often communication will be broken into two steps. Key exchange and data exchange. For key exchange, to protect the key used in data exchange it is often encrypted using public key encryption. Although slower than symmetric key encryption, this method ensures the key cannot accessed by a 3rd party while being transferred. Since the key has been transferred using a secure channel, a symmetric key can be used for data exchange. In some cases, data exchange may be done using public key encryption. If this is the case, often the data exchange will be done using a small key size to reduce the processing time. The second reason that both may be used is when a symmetric key is used and the key needs to be provided to multiple users. For example, if you are using encryption file system (EFS) this allows multiple users to access the same file, which includes recovery users. In order to make this possible, multiple copies of the same key are stored in the file and protected from being read by encrypting it with the public key of each user that requires access.

How Does Monero Work?
 
23:05
Monero is a cryptocurrency that enables private transactions. That means the sender, receiver, and transaction amount are not publicly viewable, unlike Bitcoin's blockchain. Monero's transactions stay private using the technology of ring signatures, ringCT, stealth addresses, and I2P routing. I'll explain how all of this works in this video. I do not condone the use of this technology for illegal transactions. This is powerful stuff, ideally, we start using this as a stepping stone towards a world where we get paid for our transactional data (and all the rest of our data). You'll find the jupyter notebook for this video and the associated code that I demo in the github link below.

Mit der Passphrase den private Key in Erfahrung bringen - BIP39 Tool
 
03:58
Bei der Einrichtung mancher Wallets bekommt man oft eine Passphrase/Seed zur sicheren Aufbewahrung mitgeteilt, aber kennt den private key nicht. Falls man diesen in Erfahrungen bringen müsste, hilft ein open-source Tool: BIP 39 von Ian Coleman. Gilt natürlich nur für BIP 39 Wallets, aber das sind einige. Welche das genau sind, kann man im Internet sicher in Erfahrung bringen. Jaxx und Exodus sind es jedenfalls. Tool: https://github.com/iancoleman/bip39

How Bitcoin Works
 
09:14
Join The Tiny Handful Of People Going From Zero To $10,000 Per Month Without Spending A Dime 👉- https://www.incomeuniversity.com/quick-cash/ Understanding your wealth personality will really help get you on the right track, find out yours at http://income.tv/quiz **** Come Learn From Tim LIVE Every Week On Income TV LIVE - http://income.tv/live/ *** There is a coin that's currently worth thousands of US dollars. 0:04 It's not made of gold, or platinum, or any precious metal. In fact, it's not the kind of coin you can hold in your hand or stick in a piggy bank. I am referring to a digital currency, maybe you’ve heard of it, I'm talking about bitcoin.... 0:38 How does bitcoin work as a currency or have any value at all? 1:16 A bitcoin is a transaction on a huge global ledger called the blockchain. The blockchain records every bitcoin transaction that has ever happened. As of early 2018, the complete ledger is over 149 GBs of data – and growing. 1:56 Anybody can volunteer to keep the blockchain up to date, and a ton of people do. It all works because there are lots of people keeping track of the same thing, ensuring all transactions are accurate. 3:20 Bitcoins are kept secure, thanks to cryptography, which is why it's considered a cryptocurrency. Specifically, bitcoins stay secure because of keys, which are chunks of information that can be used to make mathematical guarantees about messages. 3:34 When you create a wallet, the account is linked with two unique keys, a private key and a public key. The private key can take data and mark it, think of this like a signature. This allows for verification of the transaction. 4:06 In this way, everyone keeping track of the blockchain knows to add my transaction to the ledger. If the public key works, that's proof that the message was signed by my private key and is something I wanted to send. 4:37 If I only have enough money to pay Olivia or Hank, but I try to pay them both, the blockchain will only verify the first transaction I made. Both the bitcoin network and wallet automatically check previous transactions to make sure wallets have enough bitcoins to send in the first place. With the blockchain being as large as it is, network delays are inevitable. This means that all ledgers will not receive the transactions requests in the same order. 5:02 Okay, bitcoin, how do you solve that problem? 6:09 Computers specifically designed to solve SHA256 hash problems take, on average, about 10 minutes to guess the solution to each one. They're churning through billions and billions of guesses before they get it right. 6:45 Volunteers running these computers spend thousands of dollars on special hardware, built to solve SHA256 problems. They are investing in massive amounts of electricity to keep the machines running. 7:24 When bitcoins were first created in 2009, they didn't have any perceived value. Tens of bitcoins would've been worth the same as a bunch of pennies. As of January 3, 2018, one bitcoin is worth over $15,000 USD. Every 12 1/2 bitcoins mined are worth over $187,500… 8:08 Eventually, there'll be so many transactions in a block that it'll still be worthwhile for miners to mostly be paid in tips – called transaction fees. According to current projections, the last bitcoin, the 21 millionth coin, will be mined in the year 2140. The decreasing number of bitcoins is modeled off the rate at which things like gold are dug out of the earth. It creates a deflationary currency whose value increases over time. Bitcoin is the first cryptocurrency in the marketplace. It has taken the world by storm and proven what the future of finance will look like.

Crypto Wallets. Was hat es mit den 12 oder 24 Wörter auf sich? BIP32, BIP39, BIP44
 
37:03
Die Mnemonic Keys, bestehend aus minimal 12 und maximal 24 Wörter, können alle Keys und Adressen einer Wallet generieren und wiederherstellen. Fast alle Multi-Coin Wallets (Ledger, Trezor, Exodus, Jaxx, ...) verwenden BIP39, also die z.B. 24 Wörter. Single-Coin Wallets, z.B. das Bitcoin Core Wallet, verwenden meist nur BIP32, also eine lange Zeichenkette. Grundlagen: Die 24 Wörter Mnemonic (Wortliste mit 2048 Wörter) oder der BIP39 Standard. Es gibt Wallets die verwenden 12 oder 18 Wörter. BIP32 Master-key aus den 24 Wörtern - wie ein mathematische Formel - gibt immer wieder dasselbe Resultat zurück. BIP44 Multi Account/Coin Hierarchie Nichts ist gespeichert! Es wird alles berechnet!!! Generierung der 24 Wörter auf z.B. Ledger durch Chip. Sicher genug! Würfeln, ab 54 Würfe sicher. Tool Entropie.

Extreme Cold Storage: A Fortress of Solitude for Bitcoins - Bitcoin News
 
07:03
Extreme Cold Storage: A Fortress of Solitude for Bitcoins Many bitcoin investors use hardware devices, paper wallets, and multi-signature solutions to keep their wealth safe from online threats such as hackers and malicious viruses. However, there are more extreme cold storage options for those who have lots of bitcoins, like $100,000 worth of BTC or more. One such process, a method called the Glacier Protocol, provides a step-by-step high-security convention for bitcoin cold storage. Self-Managed Extreme Cold StorageA lot of people rely on hardware wallets or other methods of secure bitcoin storage so they can keep their cryptocurrency safe. Most people are ok with the amount of security these types of wallets provide, but there are more extreme measures of cold storage. One of these methods is a self-managed solution called the Glacier Protocol which offers free software for a method that keeps private keys secure, isolated, and offline. The solution is not intended for those who want to use their bitcoin on a daily basis and is more for those looking for a more critical security framework. The Glacier Protocols target audience is meant for those who dont trust USB connection vulnerabilities, and general offline key creation.

BTC - Low Power Private Full Node - Hardware Info
 
21:50
Sorry I still had browser nitemares in this vid - I uninstalled and reinstalled older AMD drivers after this vid, and have done test runs since and it seems sooo much better...so this vid is hopefully the last vid with browser nitemares... so much for upgrades being better... I hope something in this vid is usefull to someone...as I say, professionally amateur... Cheers for watching... !!! :) BTC - Low Power Private Full Node - Hardware Info ============================================== I think a Raspberry Pi 2 B is probably enough spec, and a USB 500GB hard disk should be enough space for at least a year...well, lets frickin hope so, cos the blockchain is currently "only" about 120GB...!!!!!!! We just gotta see what happens with the "BTC HardFork" / "Block Size Increase "Circus Show" ", that it seems to have become... If theres "available bandwidth" for increasing the "physical" block size, then theres damn well available bandwidth for us to run private full nodes just to be able to securely access our wallet without relying on a third party service of some type or other...!!! I'm gonna try my best to document what needs documenting so others can hopefully benefit by doing the same, with bitcoin, or any other altcoin, although I highly recommend making your altcoin Full Node pubicly accessible to other nodes to help support the network for the coin or coins you have - just disable loading the wallet part unless you need it loaded - that will help secure your coins !!! Bitcoin Core currently only needs about 512MB of ram, if I remember correctly, but that means the device has to have more then 512MB RAM... 1 GB should be enough if its not doing too much else aswell... Perhaps a Raspberry Pi 3 B might be better instead for some people...I'm a bit of a fan of "one device, one task" although that is not always possible...factors can easily be dependant on other factors... :) These specs should work just as well for DASH or Litecoin Core as far as I am aware, aswell as many others I'm sure... That will probably come in the near future too, for me anyway... :) Cheers !!! :)

DEF CON 23 - Ryan Castellucci - Cracking CryptoCurrency Brainwallets
 
42:49
Imagine a bank that, by design, made everyone's password hashes and balances public. No two-factor authentication, no backsies on transfers. Welcome to "brainwallets", a way for truly paranoid cryptocurrency users to wager their fortunes on their ability to choose a good password or passphrase. Over the last decade, we've seen the same story play out dozens of times - a website is broken into, the user database is posted online, and most of the password hashes are cracked. Computers are now able make millions, billions or even trillions of guesses per second. Every eight character password you can type on a standard keyboard and every combination of five common english words could be tried in less than a day by today's botnets. Can people come up with passphrases able to stand up to that when money is on the line? Let's find out. For this talk, I will be releasing my high speed brainwallet cracker, "Brainflayer". I'll cover a history of brainwallets, safer passphrase-based wallet generation, passphrase security, in-the-wild cracking activity, and how I accidently stole 250 Bitcoins (and tracked down the owner to give them back). Ryan Castellucci has been interested in cryptography since childhood when his parents gave him a copy of "Codes, Ciphers and Secret Writing". He soon learned to program and wrote a tool to crack simple substitution ciphers. More recently, he co-spoke with Dan Kaminsky at DEF CON 22 and was a finalist in the 2014 Underhanded Crypto Contest. For his day job at White Ops, he finds new and exciting ways to tease out the subtle differences between bots and human-controlled web browsers.

Bitcoin Q&A: Protocol development security
 
12:56
What are the odds of "rogue developers" who introduce vulnerabilities? What happens if the digital signature algorithm is compromised? Is trust in hardware wallet developers and the firmware update process a problem? Note: I was mostly talking about Bitcoin and other popular open blockchains which have a large development communities and a robust review process before any new code is put in production. The risk of vulnerabilities introduced by developers is different for each project, and having open-source code does not prevent it if no one is reading or testing it. These questions were part of the monthly live Patreon Q&A session for April (rescheduled to May 5th).

What is The History of Bitcoin: Super Easy Explanation
 
12:11
What is The History of Bitcoin: Super Easy Explanation - https://blockgeeks.com/ We’ll start at the very beginning by understanding the history of blockchain. The very first blockchain in the world was Bitcoin. An anonymous person or group known as Satoshi Nakamoto published a document in an online cryptography forum in November 2008 and revealed the first details of how it would work, describing it as a “peer-to-peer electronic cash system”. The whitepaper is available today at bitcoin.org/bitcoin.pdf. It allows any 2 people to pseudonymously send money to each other no matter where they are in the world. It is a borderless currency. The main benefit of Bitcoin is that it does not require any centralized authority or institution to operate. This is in contrast to today’s centralized financial systems that depend on the existence of a central bank or government to mint money. If for any reason the central authority were to shutdown, the money would become worthless. In a decentralized system like Bitcoin, there is no central authority and the system can continue to operate as long as there are members in its peer-to-peer network. The goal of the whitepaper was to describe how the different parts of the Bitcoin protocol would operate and be kept secure. A new type of database, called a blockchain, would keep track of a single history of all Bitcoin transactions and it would be maintained by everyone in the network. The database would be publicly available for anyone to view and inspect, and anyone can download a copy of the same database. This provides data redundancy and makes sure the data is never lost, but also provides a way for anyone to verify the transactions in the database themselves. A block in the database just stores a sequence of transactions, and a sequence of blocks is called a blockchain. Each block is identified by an incrementing number and a unique Sha-256 hash. The hash for a block is calculated using the transactions inside it, as well as the previous block’s hash, which forms a chain of hashes. The data in the blocks is secured using a cryptographic algorithm called proof-of-work, which also keeps all members of the network and the database in sync to prevent double-spending. In this context, preventing double-spending means preventing anyone from spending money they dont have. Proof-of-work is used to generate new blocks for the database, also known as mining, and the reward for mining a new block is given to the miner by creating new Bitcoins in the system. This is the only way new Bitcoins can be created. Anyone on the network can be a miner and a new block is mined roughly every 10 minutes, which includes the latest set of verified transactions. The first release for Bitcoin was version 0.1 written in C++ by Satoshi and published on SourceForge in January 2009 under the open-source MIT license. Anyone could download the source code and run it to join the network, also known as becoming a node in the network. This is the original version 0.1 source code written by Satoshi. We can see the hard-coded genesis block, which is the very first block in the chain. The hash for the block can be verified by using any Bitcoin blockchain explorer. Let’s copy and paste this hash into the blockchain explorer available at blockchain.info. We can see that this hash is for block number 0, and that it has only one transaction in it which is the mining reward, and the reward amount of 50 Bitcoin was given to this Bitcoin address. We can also see this 50 Bitcoin reward for the genesis block in the original source code. The genesis block is a special case needed to start the blockchain and is the only block that is hard-coded, whereas every subsequent block is calculated using proof-of-work. Satoshi’s motivation for creating Bitcoin is revealed in the piece of data he included in the genesis block: a newspaper headline from The Times that read ‘Chancellor on brink of second bailout for banks’. The date of the newspaper is proof that the genesis block was created on or after Jan 3 2009. Satoshi developed the source code mostly himself up until mid-2010, when he handed it off to the open-source community. It is now maintained under the project called Bitcoin Core. The software is currently at version 0.15.1 and is available for download at bitcoin.org. This is still the most popular Bitcoin client, and its estimated that there are over 10 thousand nodes running the Bitcoin network today using various clients. Satoshi disappeared from public view in late 2010, his identity still unknown to this day. The only way someone could prove that they are Satoshi is by using the same encryption keys used when posting the original whitepaper in the online cryptography forum.

Bitcoin Q&A: MimbleWimble and Dandelion
 
12:03
What is the story behind MimbleWimble? What is Grin? What is a Dandelion transaction relay, as described in BIP156, and how does it improve the anonymity of the Bitcoin network? CLARIFICATION/ CORRECTION: At 1:14, I talk the origins of MimbleWimble. The PDF was submitted to the Bitcoin research IRC channel on August 2nd, 2016. The pseudonymous author used the name "Tom Elvis Jedusor," which is the French version of Voldemort's real name. I also say that the name "MimbleWimble" was referencing the name of a spell from Harry Potter, which is the Tongue-Tying Curse and prevents someone from speaking about (not "seeing") something: http://harrypotter.wikia.com/wiki/Tongue-Tying_Curse At 6:08, I was unable to list the names of the team members behind the Dandelion proposal. They are Giulia Fanti, Shaileshh Bojja Venkatakrishnan, Surya Bakshi, Bradley Denby, Shruti Bhargava, Andrew Miller and Pramod Viswanath (researchers at Carnegie Mellon, MIT, and the University of Illinois).

A 3-of-5 Multisig Wallet with Copay
 
04:09
Copay is a multisignature wallet being developed by BitPay's bitcore team. Copay has a number of innovative features that make it unlike any other wallet: * It is inherently multisignature, meaning more than one person (or device) must sign outbound transactions. This makes it next to impossible for someone to steal funds from the wallet. If one person has their private keys stolen, the funds are still safe. * It is decentralized and does not rely on centralized servers. There is a small dependence on two servers (PeerJS and Insight), both of which can be run yourself. The wallet files are stored locally in HTML5 local storage, and communication is p2p using WebRTC. * The wallet uses BIP32, which, in a nutshell, means it's really easy to back up your wallet. Back it up once, and it's backed up forever. * It is 100% open-source, both client-side and server-side. We encourage outside contributors in every aspect Copay, as well as with our other projects, Bitcore and Insight. The source code is available here: https://github.com/bitpay/copay The transaction created in the video can be seen here: http://test.insight.is/tx/10a7c5fa0eccb075fc7dc38b146b07b980a3dc95794878db3a7151571922fcdf
