teachbitcoin-cn (WIP)

https://teachbitcoin.io 的教学 PPT 翻译。配合 libbitcoin 进行 比特币 原理&编程 教学。

Libbitcoin 是一个异步的 C++ 比特币代码库. 相关文档.

内容

原文章节 简介 练习代码 译文章节
椭圆曲线数学 This chapter covers prime fields, elliptic curves operations over real numbers and prime fields. These are the basic mathematical concepts that ECDSA signing is based on. 代码 进行中
DER 签名 比特币签名使用椭圆曲线签名算法 (Elliptic Curve Digital Signing Algorithm, ECDSA) 来为未花费输出 (unspent outputs) 提供安全性,并以 DER 序列化格式进行被编码。 已完成
地址和分层确定性钱包 Bitcoin addresses encode the information required for a wallet to spend to the correct key. Hierarchical Deterministic wallets use a child-key derivation algorithm to safely derive new addresses from the same root. 代码 进行中
交易入门 An introduction to building and signing your first transaction which spends to Pay-to-Public-Key-Hash outputs. 代码 进行中
Signature Hash Modifiers Signatures can commit to specific input and outputs, allowing other parts of the transaction to be modified by other parties. 代码 进行中
多重签名脚本 An output script which can be spent by n-of-m signatures. 代码 进行中
Pay-to-Script-Hash 脚本 P2SH output scripts commit to a hashed locking script. The locking script preimage must be provided together with the unlocking script for such a P2SH output to be spent. 代码 进行中
交易时间锁 Absolute and relative timelocks prevent transactions from being broadcast before a certain time or blockheight. A timelock may be commited to by the transaction signature, or can be enforced by the previous output script. 代码 进行中
见证交易 Pay-to-witness output scripts are be spent with transactions with valid witnesses. Wallets which do not support native P2W transactions may send to outputs which wrap P2W scripts in P2SH outputs. 代码 进行中
区块链 A closer lock at blocks and block headers, and their validation by nodes. 代码 进行中
点对点(P2P)网络 An introduction to the P2P messaging protocol between Bitcoin nodes on the network. 代码 进行中
简单支付验证 SPV clients follow the longest header chain with the most proof-of-work. They rely on specific transaction updates from full Bitcoin nodes, and perform merkle proofs to validate confirmation of these transactions. 代码 进行中
支付通道和闪电网络 We demonstrate a basic payment channel between two nodes which is enabled by revocable output scripts (RSMC's). Payment routing across multiple payment channels is made possible by hashed time-locked contracts (HTLC's). 代码 进行中
