Peter, I like the idea of being able to know what fees to expect from different miners (it is like a service description / SLA for their service), but I would prefer a more distributed discovery mechanism for the information on the fees (Spent 10 years on Grid Computing...). Miners could e.g.

[Bitcoin-development] Testnet reset for the 0.7 release

Testnet Mark III will be part of the 0.7 release, and is now in the master github branch. Mark III because this is the third genesis block for the testnet. The main reason for the reset is to get a more 'sane' test network; with the BIP16 and BIP30 and testnet difficulty blockchain rule changes

OK, I have a few thoughts on this: 1) Germane to the original conversation, anything hard to implement will not get implemented by miners. 2) Coinbase is hard-limited to 100 bytes; this has to include space for voting as well as extra nonce, etc. So, I'm not sure that a full URL is a good plan.

I suppose I mean that I don't understand how to reverse that into a URL when one is presented only with a block, or perhaps a coinbase in a transaction. Best, Peter On Tue, May 29, 2012 at 11:34 AM, Luke-Jr l...@dashjr.org wrote: On Tuesday, May 29, 2012 3:28:56 PM Peter Vessenes wrote: I

I see. That is undeniably more secure and bitcoin-y than my suggestion. It's also really a lot more work, especially in that it requires extra linkages between codebases that in my mind are largely separate. I'm just one voice, but I persist in believing that the 'lighter' solution, especially

I disagree with a bunch of your points, but I'll wait on others to comment, except I will say that I don't understand what the 20 byte keyhash is. Can you elucidate? I am assuming major mining folks have written their own coinbasing facilities, but perhaps this is not the case -- if so, I agree
