Advanced Bitcoin Scripting -- Part 1: Transactions & Multisig
 
59:58
This is the first part of a more technical talk where Andreas explores Bitcoin script, with examples from the 2nd edition of Mastering Bitcoin, focusing on the use of conditional statements, flow control, guard clauses and time locks. The examples will include advanced multi-signature scripts, hash time lock contracts and asymmetric revocable commitments. Then he answers questions about Bitcoin's quirky bugs, where Bitcoin differs from Ethereum at a scripting level, how SegWit works, how consensus rules change, and whether Bitcoin is more than just a currency.

Bitcoin Q&A: Offline transactions and fault tolerance
 
05:06
Is it possible to do a bitcoin transaction without using the internet? How do transactions from paper wallets and physical bitcoins work? Does this solve the Byzantine Generals' Problem? NOTE: OpenDimes utilize some additional security measures, especially regarding key generation, which paper wallets and other physical bitcoins do not. When sealed, the public key is accessible and you are able to check the balance, but you cannot access the private key without unsealing, i.e. breaking part of the hardware device. Learn more about how they work here: https://opendime.com/faq This question is from the MOOC session 8.2 covering the Byzantine Generals' Problem, which took place on September 15th 2017. Andreas is a teaching fellow with the University of Nicosia. The first course in their Master of Science in Digital Currency degree, DFIN-511: Introduction to Digital Currencies, is offered for free as an open enrollment MOOC course to anyone interested in learning about the fundamental principles.

Blockchain tutorial 27: Bitcoin raw transaction and transaction id
 
12:17
This is part 27 of the Blockchain tutorial. This tutorial explains: - What Bitcoin raw transaction is. - Shows an example of a raw transaction using the very first transaction on the Genesis block. - What the difference is between big endian and little endian. - What a satoshi is. - What a Bitcoin transaction id or hash is and what its purpose is. - How to calculate the transaction id. In this video series different topics will be explained which will help you to understand blockchain. Bitcoin released as open source software in 2009 is a cryptocurrency invented by Satoshi Nakamoto (unidentified person or group of persons). After the introduction of Bitcoin many Bitcoin alternatives were created. These alternate cryptocurrencies are called Altcoins (Litecoin, Dodgecoin etc). Bitcoin's underlying technology is called Blockchain. The Blockchain is a distributed decentralized incorruptible database (ledger) that records blocks of digital information. Each block contains a timestamp and a link to a previous block. Soon people realises that there many other use cases where the Blockchain technology can be applied and not just as a cryptocurrency application. New Blockchain platforms were created based on the Blockchain technology, one of which is called Ethereum. Ethereum focuses on running programming code, called smart contracts, on any decentralized application. Using the new Blockchain platforms, Blockchain technology can be used in supply chain management, healthcare, real estate, identity management, voting, internet of things, etcetera, just to name a few. Today there is a growing interest in Blockchain not only in the financial sector but also in other sectors. Explaining how Blockchain works is not easy and for many the Blockchain technology remains an elusive concept. This video series tries to explain Blockchain to a large audience but from the bottom up. Keywords often used in Blockchain conversation will be explained. Each Blockchain video is short and to the point. It is recommended to watch each video sequentially as I may refer to certain Blockchain topics explained earlier.

Bitcoin Q&A: What is Segregated Witness?
 
14:41
What is Segregated Witness (SegWit)? How do you know you’re using SegWit? SegWit fixes transaction malleability and enables further upgrades towards Bitcoin smart contracts. Can transaction malleability lead to denial-of-service (DoS) attacks? Does SegWit put witness data in a different block? Did SegWit change transaction validation? versus? Are there any security risks of invalid blocks? CORRECTION: At ~2:07, I stated the incorrect BIP number for the Bech32 address format, which should be BIP173. BIP176 is about "bits" denomination. https://github.com/bitcoin/bips/blob/master/bip-0173.mediawiki More on SegWit: https://bitcoincore.org/en/2016/01/26/segwit-benefits/ These questions are from the MOOC 9.3 and 9.5 sessions which took place on March 2nd and March 16th, 2018 respectively.

XSPOCT - Private Bitcoin transactions - a detailed introduction
 
24:55
XSPOCT - XCredits-Style Private Off-Chain Transactions is a new way to send Bitcoin (or more precisely, an analogue of Bitcoin). It achieves this by only putting the proof that a transaction has occurred (in the form of a hash) not the transaction details (like which address it is going to or from, and how much is being sent).

09:55
Hey guys! In this episode of Bitcoin Basics I will show you step by step on how to download, install and set up a Hot Wallet, in this case, Mycelium Bitcoin Wallet, one of my favorite open source basic wallets to get you started. Please remember to Back up, Set a PIN code and click on 'Require PIN when you open the App'. Also note that the application might give you a new address from time to time which is for security purposes. If by any chance someone sends you Bitcoin to a previous address that's no problem as ALL your old addresses are still valid. Even if you are not ready to buy bitcoin at this point I highly recommend you to BE READY when you are convinced to start your journey. If you have any questions please let me know! Thanks :)

While I use the Ropsten test network for this example, the steps are exactly the same for the Ethereum main network. The virtual machine shown in this video was created specifically without any network connectivity for the purpose of this video. Using an actual offline computer works the same by utilizing a USB thumb drive to transfer the text between the offline and online computers.

Bitcoin | How it works?
 
09:10
Bitcoin is a cryptocurrency and worldwide payment system. It is the first decentralized digital currency, as the system works without a central bank or single administrator. The network is peer-to-peer and transactions take place between users directly, without an intermediary. These transactions are verified by network nodes through the use of cryptography and recorded in a public distributed ledger called a blockchain. Bitcoin was invented by an unknown person or group of people under the name Satoshi Nakamoto and released as open-source software in 2009. Bitcoins are created as a reward for a process known as mining. They can be exchanged for other currencies,products, and services. The blockchain is a public ledger that records bitcoin transactions. In this video we will see : - What is Bitcoin - Price of Bitcoin - Why it is important - Digital CryptoCurrency - How bitcoin looks - How can we use bitcoin - Units of Bitcoin - Satoshi - Miners - Blockchain

The Bitcoin Lightning Network Explained - Andreas M. Antonopoulos
 
28:01
What is the capacity difference between utilizing second layers, like the Lightning Network, and block size increases? Are Lightning Network transactions still bitcoin transactions? Do you have to be online? What happens when a party does not commit to an action / send a reimbursement in LN? How will the Lightning Network handle DDoS attacks? How does node banning work? Will Lightning Network and other second layers have interoperability? Lightning Network is a proposed implementation of Hashed Timelock Contracts (HTLCs) with bi-directional payment channels which allows payments to be securely routed across multiple peer-to-peer payment channels. This allows the formation of a network where any peer on the network can pay any other peer even if they don’t directly have a channel open between each other. These questions are from the MOOC 9.5 session and the monthly live Patreon Q&A session.

Blockchain tutorial 26: Bitcoin transaction
 
21:55
This is part 26 of the Blockchain tutorial explaining how to make a bitcoin transaction. A real demonstration is given how to make a bitcoin transaction on the Bitcoin Testnet. This tutorial shows the following: - How to create multiple public and private bitcoin Testnet key pairs. - How to claim some bitcoins from a faucet and transfer it to a sender address. - How to make a bitcoin transaction by transferring all bitcoins from a sender address to receiver address. This tutorial also explains: - What UTXO (Unspent Transaction Output) is. - What a confirmation is. In this video series different topics will be explained which will help you to understand blockchain. Bitcoin released as open source software in 2009 is a cryptocurrency invented by Satoshi Nakamoto (unidentified person or group of persons). After the introduction of Bitcoin many Bitcoin alternatives were created. These alternate cryptocurrencies are called Altcoins (Litecoin, Dodgecoin etc). Bitcoin's underlying technology is called Blockchain. The Blockchain is a distributed decentralized incorruptible database (ledger) that records blocks of digital information. Each block contains a timestamp and a link to a previous block. Soon people realises that there many other use cases where the Blockchain technology can be applied and not just as a cryptocurrency application. New Blockchain platforms were created based on the Blockchain technology, one of which is called Ethereum. Ethereum focuses on running programming code, called smart contracts, on any decentralized application. Using the new Blockchain platforms, Blockchain technology can be used in supply chain management, healthcare, real estate, identity management, voting, internet of things, etcetera, just to name a few. Today there is a growing interest in Blockchain not only in the financial sector but also in other sectors. Explaining how Blockchain works is not easy and for many the Blockchain technology remains an elusive concept. This video series tries to explain Blockchain to a large audience but from the bottom up. Keywords often used in Blockchain conversation will be explained. Each Blockchain video is short and to the point. It is recommended to watch each video sequentially as I may refer to certain Blockchain topics explained earlier.

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.

Which cryptocurrency blockchain has the most transactions per day?
 
12:57
Would you join us in discovering which blockchain has the most transactions daily because knowing this helps determine which cryptocurrency truly is valuable and which is likely to be pure speculation? The reason fiat currencies like USD have value is the ability to transact. A key indication of the true value of a currency is how much it is being used. With cryptocurrencies the same rule applies because a currency that has many users sending and receiving money is worth buying while anything that has a low amount of activity is likely overvalued and best to sell. For example, Ethereum actually has more transactions than Bitcoin today but Steem has more than both of them combined even with a fraction of the number of users!

What will OP_DATASIGVERIFY and Canonical Transaction Ordering (CTOR) do? Does the original chain still exist? Is there a hash war going on? What happens to coins from the prior BCH chain? What is replay protection? These questions are from the November monthly Patreon session, which took place on November 17th 2018.
