Create a Bitcoin Pay-to-Public-Key-Hash BlockchainTransaction:
btcTX = BlockchainTransaction[<|"Inputs" -> {<|"TransactionID" -> "9bef194418607318673caaf8f45d52fb60e8c8586e6ce8414c377a279ca14399", "Index" -> 0|>}, "Outputs" -> {<|"Amount" -> Quantity[0.0002, "Bitcoins"], "Address" -> "munDTMqa9V9Uhi3P21FpkY8UfYzvQqpmoQ"|>, <|"Amount" -> Quantity[0.16223, "Bitcoins"], "Address" -> "mo9QWLSJ1g1ENrTkhK9SSyw7cYJfJLU8QH"|>}, "BlockchainBase" -> {"Bitcoin", "Testnet"}|>]Sign the transaction object using a WIF-encoded private key:
BlockchainTransactionSign[btcTX, "6a25394168f52156c58bbf4924e8c82da0d8bcb581f8baac6d67a5d3556a5e76"]Scope (1)
