- 数字货币的三大问题
- 真币，假币？ 纸币通过复杂纸张和印刷技术，不断与伪造问题作斗争。
- 这笔钱只能被花费一次吗（双花问题）？ 纸币只有一张，也就不会同时出现在两个地方。比特币通过POW机制解决双花问题。
- 这笔钱只能被我拥有吗？ 纸币，在谁手里就是谁的。比特币通过数字签名解决所有权问题。
- 随着加密技术的发展，在比特币之前，也存在数字货币，但都是中心化的。
- four key innovations
- A decentralized peer-to-peer network (the Bitcoin protocol)
- A public transaction journal (the blockchain)
- A set of rules for independent transaction validation and currency issuance (consensus rules)
- A mechanism for reaching global decentralized consensus on the valid block‐ chain (proof-of-work algorithm)
- 比特币提案 Bitcoin Improvement Proposals (BIPs).
The Bitcoin transaction script language contains many operators, but is deliberately limited in one important way—there are no loops or complex flow control capabili‐ ties other than conditional flow control.
