From your command line:\n\n#### Source\n\nYou'll need [Git](https://git-scm.com) to run the project from source. From your\ncommand line:\n\n```bash\n# Clone this repository\n$ git clone https://github.com/seanseany/blockchain\n\n# Go into the repository\n$ cd blockchain\n\n# Install dependencies\n$ npm install\n\n# Run the app\n$ npm start\n```\n\n## ℹ️ FAQ\n\n#### When or why I would use this?\n\nYou should use this if you want to build a bitcoin wallet, payment processor, or\nbitcoin merchant portal in javascript. You might also be interested in why\ndecentralized networks or p2p applications are useful, or what advantages they\nhave; this project seems like a good way to learn about that.\n\n#### What is the block chain actually for?\n\nThe blockchain is for authorizing payments of a cryptocurrency between two peers\nwithout the need for a centralized 3rd party approving of the transaction. There\nare other uses of the blockchain which are more in line with the second point,\ndigital signatures, but they are secondary to the main purpose of peer to peer\ntransfer of value. Bitcoin is blockchain's killer app.\n\n#### Why the hell should I care about the blockchain?\n\nBlockchain facilitates trade over a network. Imagine a metal as scarce as gold\nwith a magical property of \"can be transported over a communications channel\".\nThis has implications with respect to individual rights, the world economy, and\nthe way we monetize and transfer value at a level higher than bartering directly\nfor goods.\n\nLately people are distancing themselves from the proof-of-work concept and are\nusing blockchain to describe only the mechanism of signing a transaction as\nverification of sending an amount. Change \"sending an amount\" to almost anything\nelse - authorizing a change in a ruleset, casting a vote for a politician,\nverifying a point of IoT data is authentic. Now add in the concept of a\npeer-to-peer network to this and you've eliminated a middleman that once\nexisted, thereby improving the efficiency and reducing cost. In these cases,\n\"blockchain\" refers to the structuring of a program or database in such a way\nthat it has no central point of failure while still providing all of the\nfeatures expected. For example, augur and gnosis are decentralized prediction\nmarkets. Ethereum has implemented smart contracts which enable decentralized\nrelease of funds based on a gambling outcome.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2F0xs34n%2Fblockchain","html_url":"https://awesome.ecosyste.ms/projects/github.com%2F0xs34n%2Fblockchain","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2F0xs34n%2Fblockchain/lists"}
