加密货币不需要区块链
大多数人认为“加密货币”意味着区块链。像比特币和以太坊这样的公共账本，每一笔交易都被永久记录。但区块链从来不是为了隐私而设计的。它们默认是显而易见的，设计上就是透明的。每一笔支付都是一种广播，每一个余额都是一个公共文件。
在干净的系统中，这可能没什么问题。但在网络朋克经济中——混乱、低信任、充满监视者——广播你整个财务生活不仅是不必要的，还是危险的。

Most people think “crypto” means blockchain. Big public ledgers like Bitcoin and Ethereum where every transaction is stamped into eternity. But blockchains were never designed for privacy. They're loud by default. Transparent by design. Every payment is a broadcast. Every balance, a public file.<p>That might be fine in clean systems. But in cyberpunk economics — messy, low-trust, and full of watchers — broadcasting your entire financial life is not just unnecessary. It’s dangerous.<p>https://www.gizvault.com/archives/crypto-doesnt-need-blockchain
