Re: [Bitcoin-development] Pubkey addresses
I propose that full public key addresses be required to be compact (length 33), and use version 21 (begins with '4', and is redundant with ver 20 for 20- byte data). Any reason this wouldn't be workable? -- Learn Windows Azure Live! Tuesday, Dec 13, 2011 Microsoft is holding a special Learn Windows Azure training event for developers.

Re: [Bitcoin-development] Protocol extensions
While using DHT for storage of the block chain is an intriguing concept, I do not see how it is feasible. As Gavin noted, DHT is a system that is difficult to impossible to guarantee against data loss or manipulation. Even if we found a way to store the block chain in DHT, how would transactions be verified? As Gavin noted, you could ask the network, but cannot necessarily trust the peers you are connected to. Verification of the full block chain allows the client to trust no one. I also do not see how DHT would solve the problem of scalability in regards to broadcast messages, although I am definitely interested in the concept. -- Learn Windows Azure Live!

Verification of the full block chain allows the client to trust no one. Well, the block chain data itself is internally self-validating. As long as you know the latest block's hash -- a big if -- there is no problem downloading all other block chain data from DHT or any other untrusted source. In a malicious case, you would notice latest-hash differs from non-malicious and wind up downloading multiple chains, when walking hashes backwards through a DHT/lookup table. So, a bit more work but nothing fundamentally less secure _on a trust basis_. Of course, I was focusing on data validation, which ignores other factors such as DoS'ing the DHT. -- Jeff Garzik exMULTI, Inc. jgar...@exmulti.com -- Learn Windows Azure Live!
