You might find my 0.4.x backport helpful: https://github.com/luke-jr/bitcoin/commit/bip16_0.4.x Be aware, this still needs auditing (nobody else has looked it over), but I believe should cover only the minimal changes required to get P2SH validation (though not the "standard" rule changes to accept them into blocks). -- This SF email is sponsosred by: Try Windows Azure free for 90 days Click Here http://p.sf.net/sfu/sfd2d-msazure ___ Bitcoin-development mailing list Bitcoin-development@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/bitcoin-development
[Bitcoin-development] BIP 16 changes (list inside)
Hi, Is this an accurate and precise summary of the changes needed for P2SH and BIP 16? == Block validation (starting with ProcessBlock) == * SigOpCount is now a LegacySigOpCount (CheckBlock) * Main body of AcceptBlock() and rest of ProcessBlock() is unchanged. * AddToBlockIndex() unchanged * Some nice efficient improvements to SetBestChain(), but not related to BIP 16 * ConnectBlock() has new SigOp calculation. * No important changes to FetchInputs()/ConnectInputs() == Script == * Solver has special case to check for TX_SCRIPTHASH. Returns hash of input eval script * Another Solver which a) returns signature of pubkey script or b) TX_SCRIPTHASH - finds redeem script in KeyStore and returns it. * ExtractAddress(es) * VerifyScript: ** After running input script (scriptSig), copy stack ** Evaluate script as normal ** if block date (fValidatePayToScriptHash) and output script (scriptPubKey) is P2SH: *** scriptSig must be only push operations *** evaluate last item of copied stack as a script using the copied stack as the stack * SigOpCount (used inside CBlock::ConnectBlock main loop) does scoring checksigs and multisigs. ** Newly added DecodeOP_N to normal SigOpCount == Address == * Set main hash160 data with a beginning byte (nVersion) of 0x05 -- This SF email is sponsosred by: Try Windows Azure free for 90 days Click Here http://p.sf.net/sfu/sfd2d-msazure ___ Bitcoin-development mailing list Bitcoin-development@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/bitcoin-development
