i'm studying Bitcoin: A Peer-to-Peer Electronic Cash System Satoshi Nakamoto
and this paper introduce a transaction model. (above picture)
but i don't understand what is 'Hash' means exactly
i think Hash is same Bitcoin API JSON-RPC - signrawtransaction
function
it means hash(txid + owner's public key)? then what method used hash function?
or hash(result of signrawtransaction
+ RIPEMD160(sha256(pub k)) )? then what method used to hash?
