中本聪致迈克·赫恩:ECDSA 曲线选择(2009 年 4 月 18 日)
首次公开证据
打开首次公开证据我发回了 32.51 和 50.00。
我非常想找到一种办法,让间接转账也能包含评论,但确实没有办法。比特币使用 EC-DSA,这对于让区块链足够紧凑、从而在当今技术条件下具有实用性至关重要,因为它的签名比 RSA 小一个数量级。但 EC-DSA 不能像 RSA 那样加密消息,它只能用于验证签名。

I sent back 32.51 and 50.00.
I badly wanted to find some way to include a comment with indirect transfers, but there just wasn't a way to do it. Bitcoin uses EC-DSA, which was essential for making the block chain compact enough to be practical with today's technology because its signatures are an order of magnitude smaller than RSA. But EC-DSA can't encrypt messages like RSA, it can only be used to verify signatures.
