+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.
