Possible to check who signed the transaction in a multi-sig transaction case?

Possible to check who signed the transaction in a multi-sig transaction case?

Say you have a multi-sig tx that originated from a 2-of-3 P2SH address.

Is it possible to say who signed the transaction? i.e. you can get access to the redeem script once the tx is broadcasted, and thus you have access to all 3 public keys that generated the 2-of-3 P2SH address. Arguably you can identify which public keys signed the transaction?

If yes, then how?

How to discover startup flags or command-line options for bitcoind?

How to discover startup flags or command-line options for bitcoind? I'd like to query the Bitcoin daemon (bitcoind) to find out what startup flags (command-line options) were sent to it on startup (or the current state if it has changed, e.g. -server=0/1 changing). For example, I may want to know if -addresstype, -disablewallet, -rescan, or -uacomment=<cmt> or some other flag has been set. Or for Namecoin, it would be very useful to know if -namehistory has been set. Is there an RPC or any other method to find out? Or, to ask the question a different way... src/bitcoind.cpp's bool AppInit(int argc, char* argv[]) method calls ParseParameters(argc, argv);, which is in src/util.cpp. In src/util.cpp we have: map<string, string> mapArgs; static map<string, vector<string> > _mapMultiArgs; const map<string, vector<string> >& mapMultiArgs = _mapMultiArgs; To store flags/options/args. I'd basically just like to get whatever is in tho...

Is there any python library could be used to decodescript in output

Is there any python library could be used to decodescript in output For example decode the ScriptPubKey like 4104678afdb0fe5548271967f1a67130b7105cd6a828e03909a67962e0ea1f61deb649f6bc3f4cef38c4f35504e51ec112de5c384df7ba0b8d578a4c702b6bf11d5fac to some data like this { "result": { "asm": "04678afdb0fe5548271967f1a67130b7105cd6a828e03909a67962e0ea1f61deb649f6bc3f4cef38c4f35504e51ec112de5c384df7ba0b8d578a4c702b6bf11d5f OP_CHECKSIG", "reqSigs": 1, "type": "pubkey", "addresses": [ "1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa" ], "p2sh": "3DjjKyU38gSfuVxajV43MUy4vHkg1JVL7T" }, "error": null, "id": null } In general, something like the function in decodescript rpc. http://chainquery.com/bitcoin-api/decodescript https://ift.tt/2PH91gl
