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.

Bitcoincard - Standalone hardware bitcoin client
 
04:29
Bitcoin card Standalone hardware bitcoin client: even more anonymity and reliability for bitcoin Radio enabled smartcards as a self-sustainable wireless media: no recharge and no immediate internet connection needed Functions The reliability of the Bitcoin system is assured primarily by encryption. The system's main vulnerability is the Bitcoin wallet, created as a file on the computer. If a hacker (or a computer virus) gains access to the computer and can read this file, he (it) will be able to transfer all the money to his (its) anonymous account where it will be nearly impossible to find. It will also be impossible to prove to anyone that you did not voluntarily transfer the money to your own anonymous account. Our Bitcoincard, a stand-alone device that in effect acts as an electronic wallet, can be used to hide the wallet in a safe place (outside the computer, making it inaccessible to hackers). It is worth noting in this regard that: digital signature keys are created and stored inside the card, and never leave it; the card does not have an operating system or the ability to download additional software, which protects the card from attacks by viruses; the exchange protocol with the outside world is simple and protected by encryption; if the card is lost, the money it contains is also irrecoverably lost; the card is completely anonymous; the card has unmatched energy efficiency, and does not need to be charged; the card has unprecedented processing power for an ordinary smart card; the cards can perform peer to peer transactions using their own radio protocol in the absence of any communications infrastructure; the cards should periodically come close to any gateway in order to synchronize their state with the global bitcoin system. In essence, Bitcoincards are Bitcoin clients and support the following operations: creation of an electronic wallet (addresses); receipt of coins from Bitcoin clients; transfer of coins to Bitcoin clients; transfer of coins from card to card (bypassing the Bitcoin system during transfer, but having all transactions subsequently recorded in the system and verified by it).

What is a Bitcoin Node? - Step by Step Explanation
 
05:47
What is A Bitcoin Node. Step by Step Explanation https://blockgeeks.com/ The bitcoin network consists of a network of nodes, which are just computers or servers running the Bitcoin software. The code ensures the nodes can find and establish connection with other nodes and hence form a network that is used by the various nodes to transfer information, like transactions, blocks and other data. Through this web of interconnecting nodes, bitcoin can send digital cash securely through the network. The underlying bitcoin code implements the bitcoin protocol. So how does a new node join the bitcoin network? First it must discover at least one peer to connect to and then it can get a list of other peers from that initial peer. There are a few methods a node can use to connect to its first peer. The bitcoin client contains a hardcoded list of well known DNS servers which can return a list of ip addresses of bitcoin nodes. Alternatively, the bitcoin client can be given a static ip address of a peer if one is known. You can pass this ip address as a parameter when starting the bitcoin client software through the command line. It’s important to note that bitcoin’s network topology is not geographically defined, so the physical location of the nodes in relation to one another is irrelevant.This means a node can find and connect to any other node regardless of where it is in the world. Once a node has the ip address of a peer, it then goes through an initial handshake to establish a connection with a remote node. First the local node will send a version message to the peer which contains some basic information about itself. This will always be the first message sent by any peer to another peer. The remote peer receiving the message will examine if the sender’s version is compatible with its own version. If it is, it will acknowledge the version message and establish a connection by sending a “version acknowledgment” message, which consists only of a message header with the command string “verack”. Once a node establishes connections with one or more peers, it will exchange some information with these peers. For example, nodes can exchange ip addr of their connected peers, so each node can maintain a list of peers that it can use to re-establish connection in the future since nodes can leave and join the network at anytime. A Node can also ask its peers what the length of their local copy of the blockchain is. It can then determine if it’s own copy of the blockchain is missing any blocks, and if so, can ask its peers to send the missing blocks. Of course it can also send blocks to other nodes who do not have as much data as itself. Let’s take a closer look at the various nodes in the network. Although all the nodes participate in the network, they have different roles depending on the functionalities they want to support. There are 4 major functions: routing, storage, mining and wallet services. The bitcoin core client implementation in c++ has all four of these functionalities. Routing is the bare minimum functionality a node must support in order to participate in the bitcoin network. It contains the functionality to discover and connect to other peers in the network and it also validates and propagates transactions and blocks through the network. It serves the purpose of keeping the network connection alive and passing information through the network. A node is called a full blockchain node if it stores a local copy of the entire blockchain database. A full node can autonomously and authoritatively verify any transactions without any external references. With a full node you get complete independence and freedom from central authority at the cost of hardware storage space. A mining node serve the special purpose of creating a new block to add to the blockchain. Mining nodes runs special mining software in order to solve a cryptographic puzzle to win mining rewards. They serve the purpose of adding new transactions into the blockchain. To learn more visit us at blockgeeks.com

Bitcore Node Installation - Bitcoin MentorMonday #3
 
11:57
Greetings heroes! Mentor's Monday is a little bit postponed this week, because of the Easter, so we have a Monday on Wednesday! Last week I shared a couple of links with you and our main goal was to create and track the transaction from the command line. If you did not have don't worry - I'll help you with a short video (I'll share it when it will be uploaded. I'm still fighting with that). This step is extremely important for the next chapters so, please, install the bitcore node on you local machine. This week will be dedicated for getting familiar with basic npm packages responsible for communication with the Bitcoin network and getting basic information from the Blockchain. We will setup a simple node.js client that will gather information about last block and included transactions. To do it we have to learn a little bit more: *MUST HAVE* - A fully implemented transaction lifecycle with node.js - https://x-team.com/become-blockchain-developer/transaction-lifecycle/ - Bitcore library - https://github.com/bitpay/bitcore-lib - Explore Bitcoin library - https://github.com/bitpay/bitcore-explorers *SHOULD HAVE* - Setting up node.js app with external Bitcoin API - https://www.youtube.com/watch?v=lUiKpNU2Tx4 Well, that's it. This week is mostly practicing. So here's your homework: Create a simple node.js application, install required modules and connect to your node from previous week. Try got get an information about last block and mined transactions. See you next week!

How to do CPU Bitcoin mining on Windows with rpcminer

If you want a text tutorial along with the video, check it out at my website: This is an in depth video on how to do CPU mining on Windows with rpcminer. You can also use guiminer or bitmoose or a few other programs, but I have found the CPU mining on those to be unusually difficult sometimes, rpcminer is the only one that consistently works. For GPU mining, I would suggest guiminer. The mining pool site (where you set up an account): The site to download rpcminer: command to start cpu mining (has to be run in the directory where the program is): rpcminer-cpu.exe -url= -user=pascal11110.guest -password=guest -threads=4 -workrefreshms=100 Slush may complain that you are using getwork (an old method), if that is the case, download and run his proxy: then leave it running, and chage the command when running rpcminer from -url= to -url= The client I use as my Bitcoin wallet is Bitcoin qt, which can be downloaded here: A great chart of what to expect for speeds for a piece of hardware can be found here: Want to get free bitcoins? It doesn't pay much, but if you're just starting out and want a few for your wallet, you can get very small amounts of free coins from this site for visiting other websites: And this one gives you small amounts for just putting in your receiving address every day: You can also earn bitcoins by having people click on URL's you shorten, it just takes them to an ad before it brings them to the site it was linking to, works very well: If you are interested in understanding paper bitcoin wallets, this is a good description on reddit (some profanity): And if you want to learn more abput bitcoin in general, I highly suggest reddit's bitcoin subreddit: I now accept donations through Bitcoins!

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. ....

⚡️ Bitcoin via Lightning Network is Stupid Fast! ⚡️
 
03:30
I built a RaspiBolt (Bitcoin & Lightning full node on a Raspberry Pi) for around $150 USD. It's essentially the same as a Casa Node without the nice web UI for half the price. Also made a video demonstrating how stupid fast Bitcoin via Lightning Network ("Bitcoin Lightning") is by placing an actual eCommerce order and making a micropayment. In my demo I'm using the command-line client, but there are much more user friendlier graphical interfaces out there for mobile/desktop. Hoping once you see how stupid fast Bitcoin Lightning is, and maybe make a transaction yourself, you'll be more inclined to accept it as payment. You don't necessarily need to host your own full node, but it's nice to have one, especially if you're an enthusiast. It's fun, you'll learn a lot, and help secure the network! If building one is too much for you, I highly recommend the Casa Node as it's a plug & go solution, otherwise here's what what you'll need: You can buy these parts on ThePiHut.com: - Raspberry Pi 3+ ($44 USD) - Heatsinks ($4 USD) - Quattro Case with VESA Mount ($12 USD) - Universal Power Supply (5.1V 2.5A) ($11 USD) - Raspbian Preinstalled 16GB Micro SD Card ($11 USD) And these on Amazon.com: - USB 3.0 to 2.5" SATA III Adapter Cable ($11 USD) - 1TB 2.5" 5.4K HDD (~$50 USD) or 500GB 2.5" SSD ($72 USD) Once the hardware is acquired and assembled the rest is pretty straightforward thanks to Stadicus' guide on GitHub here: https://git.io/fhf6H Just follow it and you'll have your RaspiBolt up and running in no time! Come and Ride the Lightning! ⚡️
