Knowledge base

• Blockchain is a continuously growing list of records, called blocks, which are linked and secured using cryptography. Each block typically contains a hash pointer as a link to a previous block, a timestamp and transaction data. It enables digital currency named Bitcoin and Ethereum.
• Bitcoin is a digital asset designed by its inventor, Satoshi Nakamoto, to work as a currency.
• Ethereum is a decentralized platform that runs smart contracts on a custom built Blockchain. It provides a cryptocurrency token called "ether" and enables the decentralized web3.
• web3 is a platform for decentralized apps (dApps).
• Dapps is a Decentralized Applications on web3 which connect Frontend with Smart Contract on Blockchain.
• MetaMask is a Dapps browsers as Chrome extension. Allows you to run Ethereum dApps right in your browser without running a full Ethereum node.
• DAO : Decentralized Autonomous Organization,

Developers

• web3.js is the Ethereum compatible JavaScript API which implements the Generic JSON RPC spec. It's available on npm as a node module
• Truffle is a NodeJS Framework for Ethereum, use for compile, deploy smart contract.
• Solidity is a contract-oriented, high-level language whose syntax is similar to that of JavaScript and it is designed to target the Ethereum Virtual Machine (EVM).
• ABI : Application Binary Interface, is basically how you call functions in a contract and get data back.
• IPC : Inter-process Communications, the mechanisms an operating system provides to allow the processes to manage shared data.
• RPC : Remote Procedure Calls, a kind of request–response protocol

Missing

• Advance Solidity language
• Design Pattern
• Package management // Truffle
• Debug? // Bug!
• Deploy to other network? // Slow!
