Not with this PULL-- I think wallet security and backup is a critical feature, so that is what this is for. > I thought the plan was also to allow CHECKMULTISIG for smallish numbers of keys. groffer pointed out that might cause problems when transaction volume ramps up, because each CHECKMULTISIG counts as 20 sigops, and there is a limit to the number of sigops you can put into a block. And since it isn't needed for wallet security and backup I dropped it. Accepting this does not preclude adding more 'standard' transaction types in the future. -- -- Gavin Andresen
