谢谢你向我推荐 Wei Dai 的 b-money 论文及其他资料。
Thanks for the pointers you gave me to Wei Dai's b-money paper and others.
我刚刚发布了论文的开源实现,比特币 v0.1。详细信息、下载和截图都在 www.bitcoin.org
I just released the open source implementation of my paper, Bitcoin v0.1. Details, download and screenshots are at www.bitcoin.org
这个系统的主要想法,是生成一条基于哈希的工作量证明链,为多数共识提供不言自明的证明。用户通过向链贡献工作量证明来获得新币。
The main idea of the system is the generation of a chain of hash based proof-of-work to create self evident proof of the majority consensus. Users get new coins by contributing proof-of-work to the chain.
密码学邮件列表上曾讨论过这个设计。Hal Finney 作了一个很好的概述:
There was a discussion of the design on the Cryptography mailing list. Hal Finney gave a good high-level overview:
引用的来信Hal Finney来源 ↗我可以提一点:在很多方面,比特币是两个独立的想法。一个是解决 James 在这里列出的这类问题,也就是建立一个全局一致、但去中心化的数据库;另一个是把它用于类似 Wei Dai 的 b-money(论文中引用了它)的系统,不过是基于交易和币,而非基于账户。正如 James 所强调的,解决全局性、大规模去中心化的数据库问题,可以说是更难的部分。我认为,将工作量证明用作实现这一目的的工具,是一个很值得进一步审视的新想法。
One thing I might mention is that in many ways bitcoin is two independent ideas: a way of solving the kinds of problems James lists here, of creating a globally consistent but decentralized database; and then using it for a system similar to Wei Dai's b-money (which is referenced in the paper) but transaction/coin based rather than account based. Solving the global, massively decentralized database problem is arguably the harder part, as James emphasizes. The use of proof-of-work as a tool for this purpose is a novel idea well worth further review IMO.
