∟Confirm Outgoing Transaction

This section describes how to confirm an outgoing transaction by looking at the confirmation # in the transaction report.

Hours after I posted my outgoing transaction with the "bitcoin-cli sendtoaddress" command, I checked the transaction status as shown below:

C:\>\local\bitcoin-0.15.1\bin\bitcoin-cli.exe -testnet getrawtransaction 
   155657a1688b7f7ede2041190b055aa7b1ef427bbc343e4ef67342866934407e true

  "time": 1519056260,
  "blocktime": 1519056260
}

Surprisingly, the transaction is confirmed. It is included in the 00000000000009f95b098ba566a9e73caf70bfdf6959abc10e631f31406e7a1a clock, and followed by 19 blocks.

By looking at the "vin" entry, Bitcoin fund came from the first output of transaction da9406c4a2e1fe61f541c9298f276d6753bb3aaa7fa8ee1cc370ab41a292cd65. So let's trace it back to the sender's address in the next tutorial.
