Bitcoin from the Command Line - Sending Bitcoin Transactions Programmatically with Javascript
 
17:07
One of the common complaints with Bitcoin is that it’s pretty hard to get started, and there’s a lot of overhead to making accounts and sending transactions. So I want to show everyone a really simple workflow that I’ve been using to interact with the Bitcoin blockchain from my command line using Javascript. This isn’t a workflow that I would recommend for long-term storage (though there isn’t anything wrong with it necessarily, I still would recommend hardware wallets for long-term crypto-asset storage) but it is a good workflow for hacking around, sending money and building apps.

Let's Create A Blockchain With PHP
 
55:45
Blockchain, Cryptocurrency. Bitcoin, Ethereum. Buzzwords? Trendy topics? Sure. As a developer, I'm not very interested in the hype or the crazy speculation. But I want to understand the underlying technology. How Bitcoin works. What makes Ethereum useful. The concepts and algorithms used by Bitcoin, Ethereum, and the thousands other coins that were created in the last years. I read the Bitcoin whitepaper. I found it very interesting. To share my new knowledge, I'd like to create a cryptocurrency in PHP... with you. One hour should be more than enough. Along the way, you will hopefully better understand what makes Bitcoin revolutionary.

Watch this tutorial and get started. 🔥Hire Me: https://www.freelancer.com/u/toufiqelahy [Ask me for Source Codes] Build a blockchain and cryptocurrency. Discover the engineering ideas behind technologies like Bitcoin and Ethereum! This is the complete Cryptocurrency making Course based on blockchain technology using C#. Here, What You will Learn: How Miner’s can join the Network How Proof Of Work function Works by solving Cryptographic puzzle based on Sha256 algorithm How real-time transactions is added to the mempool How Mining Works and Generates New Coins How Transactions are added in a Block after Mining And: How new block is added in BlockChain after adding transactions in a Block How System resolve the conflicts from a longest chain by validating each block along with verifying each transactions Consencus: “How Longest chain Win” How Signature of a Transaction get verified By using public key How public and private keys get generated using RSA algorithm How Client User generates Signature using Private key And: How Wallet Transaction Works How "Blockchain Client" for users to generate wallets and send coins How to Buy digital content from Online Shopping Site using this cryptocurrency How user can check Life-time Transaction and balance How user can send coin to another user using mobile wallet after scanning QR Code How user can generate QR Code image to send/receive coins And many more…. Why Cryptocurrency is the Future? All you need is to generate public and private keys then save it in order to make transaction. No Need Bank to follow complex process Anyone can receive money using their publicKey only. And anyone can send money using wallet app to generate signature using privateKey. This is the most easiest way to transfer money within seconds. In near future the process will be so efficient that user will able to make transaction using human body parts [Artificial Intelligance] Initial Story: Anyone who will download the script can join the network by broadcasting the network and they are recognized as Miner. At genesis(initial) 1st block, only miner will have few coins. So, 1st miner will give coins to new user . Thus transactions will take place and then Miner will mine the transactions and system will give few coins to miner as reward. This way new coins get generated. Whole information is saved in miner’s machine. You will understand whole process once I will explain blockchain theory and You will better understand once you finish building Cryptocurrency application with me. How this Coin will Get Real Values If Miners confident with this script and start joining the network and if so many users do transaction with real fiat currency that time this cryptocurreny will have real values. It’s totally based on trust and faith.. And coin values also follows demand and supply rules of economic… Course Summary Within This Course: Module 1: I will explain Blockchain Theory Module 2: I will build BlockChain application then expose through web api.

Building blockchain apps with zero knowledge  by Davy Van Roy
 
50:03
Subscribe to Devoxx on YouTube @ https://bit.ly/devoxx-youtube Like Devoxx on Facebook @ https://www.facebook.com/devoxxcom Follow Devoxx on Twitter @ https://twitter.com/devoxx When developing FundRequest we noticed that building blockchain applications is not a trivial thing to do. The learning curve is steep and there are major pitfalls to make a (d)app scaleable, let alone user friendly. In short, end users should not be rocket scientists to use blockchain based applications. This is why we came up with Arkane Network. Arkane gives app developers the power to develop blockchain applications without needing the in-depth blockchain knowledge. This allows them to focus on the application, their users and optimising the str experience. Our APIs can be used by developers and businesses to make blockchain accessible to all. We will explore how we can use these API's to start building an application.

How to Create a Blockchain API Startup with Chad Bennett (Episode #12)
 
21:54
If Chad Bennett were to start a new company right now, he'd launch an API connecting companies, digital wallets, blockchains, and cryptocurrencies together. Right now, every single blockchain has a different API, which makes it hard to collaborate and create bridges between each wallet and blockchain type. Blockchain business moidels and blockchain business applications can be very difficult to understand. Chad is looking at it from a developer perspective, as opposed to a consumer-facing business, which is what this video highlights.

Blockchain tutorial 29: Hierarchical Deterministic wallet - BIP32 and BIP44
 
25:55
This is part 29 of the Blockchain tutorial. In this video series different topics will be explained which will help you to understand blockchain. It is recommended to watch each video sequentially as I may refer to certain Blockchain topics explained earlier. DETERMINISTIC WALLET BIP-39 describes how the mnemonic words are created. These mnemonic words together with a password (optionally) are used to generate a 512 bit seed. The 512 bit seed is also called the "BIP-39 seed". This seed is used to create deterministic wallets. There are two types of deterministic wallets: - Sequential deterministic wallets. - Hierarchical deterministic wallets. SEQUENTIAL DETERMINISTIC WALLET Sequential deterministic wallets generates private keys for example by taking SHA256(seed + n) HIERARCHICAL DETERMINISTIC WALLET Nowadays most wallets are Hierarchical Deterministic (HD) wallets. More information: https://github.com/bitcoin/bips/blob/master/bip-0032.mediawiki Most HD wallet vendors have implemented BIP-32, BIP-39 and BIP-44. These 3 Bitcoin Improvement Proposals are becoming an industry standard. BIP-39 BIP-39 describes the implementation of mnemonic words to generate a 512 bit seed. More information: https://github.com/bitcoin/bips/blob/master/bip-0039.mediawiki BIP-32 BIP-32 describes how you can build a general hierarchical deterministic wallet. More information: https://github.com/bitcoin/bips/blob/master/bip-0032.mediawiki https://bitcoin.org/en/developer-guide#hierarchical-deterministic-key-creation If you want to see how BIP32 is implemented in the bitcoinjs library, see: https://raw.githubusercontent.com/bitcoinjs/bitcoinjs-lib/master/src/hdnode.js Online web application: https://www.mobilefish.com/download/ethereum/hd_wallet.html BIP-32 explains how master keys and master chain code are created from a BIP-39 seed. The chain code is used as entropy in the Child Key Derivation function. Using different index numbers will create different unlinkable child keys from the same parent keys. Repeating the procedure for the child keys using the child chain code will create unlinkable grandchild keys. By changing the chain code, a new node (aka wallet) is created. Extended private (xprv) keys can create a complete branch with child private keys and child public keys Extended public (xpub) keys can only generate public keys. BIP-44 BIP-44 defines a specific logical hierarchy for deterministic wallets based on an algorithm described in BIP-32. More information: https://github.com/bitcoin/bips/blob/master/bip-0044.mediawiki BIP-44 uses the following derivation path: m/purpose'/coin_type'/account'/change/address_index The letter m denotes the master node and all hierarchical levels are separated with slashes (/). m is level 0, purpose is level 1, coin_type is level 2 etc. The purpose scheme is described in BIP-43. Because we are using BIP44 scheme we should use 44'. The apostrophe (for example in purpose') indicates hardened derivation. More information: https://github.com/satoshilabs/slips/blob/master/slip-0044.md account level can be seen as bank account types, for example payment account, savings account etc. change level is also known as "external / internal level" where external (0) is used for addresses that are meant to be visible outside of the wallet (receiving payments) and internal (1) is used for addresses which are not meant to be visible outside of the wallet (signing transactions). address_index is a sequence of addresses starting at 0. BIP-44 XPRV AND XPUB DEMONSTRATION Suppose a webshop wants to receive payments in only in ETH. For each payment received a different Ethereum address must be used. The webshop should use a wallet containing only public keys. The webshop wallet uses a xpub key with derivation path: m/44'/60'/0'/0 This wallet creates the following addresses: m/44'/60'/0'/0/0 m/44'/60'/0'/0/.. The accounting department uses another wallet containing the same public keys AND accompanied private keys. The accounting department can transfer payments made on these public addresses and transfer it to a separate accounting address. This is possible because they have access to the private keys. The accounting department wallet uses a xprv key with the same derivation path: m/44'/60'/0'/0 BIP-32 RISK If a hacker gets it hands on any child private key and the account xpub key, the hacker can recompute the account xprv key and thus have access to every private and public key descending from the account level.

Ethereum is a decentralized platform that runs smart contracts: applications that run exactly as programmed without any possibility of downtime, censorship, fraud or third-party interference. These apps run on a custom built blockchain, an enormously powerful shared global infrastructure that can move value around and represent the ownership of property. This enables developers to create markets, store registries of debts or promises, move funds in accordance with instructions given long in the past (like a will or a futures contract) and many other things that have not been invented yet, all without a middleman or counterparty risk. Using Ethereum, you can create a contract that will hold a contributor's money until any given date or goal is reached. Depending on the outcome, the funds will either be released to the project owners or safely returned to the contributors. All of this is possible without requiring a centralized arbitrator, clearinghouse or having to trust anyone. You can even use the token you created earlier to keep track of the distribution of rewards.
