I wanted to let you know, I just released the full implementation of the
|
|
|
|
|
paper I sent you a few months ago, Bitcoin v0.1. Details, download and
|
|
|
|
|
screenshots are at www.bitcoin.org
|
|
|
|
|
|
|
|
|
|
I think it achieves nearly all the goals you set out to solve in your
|
|
|
|
|
b-money paper.
|
|
|
|
|
|
|
|
|
|
The system is entirely decentralized, without any server or trusted
|
|
|
|
|
parties. The network infrastructure can support a full range of escrow
|
|
|
|
|
transactions and contracts, but for now the focus is on the basics of
|
|
|
|
|
money and transactions.
|
|
|
|
|
|
|
|
|
|
There was a discussion of the design on the Cryptography mailing list.
|
|
|
|
|
Hal Finney gave a good high-level overview:
|
|
|
|
|
| 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.
