How do I get to the value in the 'scriptPubKey' part of the transaction ?
The sender knows only the address (1A3XjcuZmcszX2tGoVn1TrMNchuHwdAxZV) so how did he get into 63339ebf4914d964fbc729b0dc4c1a44c4fb8f80 ? I've tried ripemd160(sha256(address)) didn't work . I've tried sha256(sha256(address)) didn't work.
