    hash_message.py

    Throughout the G1 Blockchain, hashes of information are used as compact identifiers to precisely refer to other sets of information.

    example from Block #1) having:
    • InnerHash: 64B858824682AB9D046F31DDACF7524FCD2501AEF269EE09E95EF2414DC9F7DB
    • bottom signature: zcF6EZF+i+U4KWsNjXGXbNNRRwO0BFjKl4EVsmpyv1qB4xzT+O2PRdkYoi8rH7/XX9stAhF+M/4pAA8YhkXKCQ==
    • Block hash: 0000238EB40E6A04B4E631FD4E2A757106D8C72C192BAE868D409D6359087C02
    • therefore BlockUID: 1-0000238EB40E6A04B4E631FD4E2A757106D8C72C192BAE868D409D6359087C02

    The InnerHash is the hash of all lines of the Block beginning with "Version:" through the last transaction (ie: InnerHash, Nonce, and the bottom signature are not included).

    $ ./hash_message.py

Paste the raw message below, (ie: InnerHash,Nonce + sig), then hit <Ctrl-D>

    The Block hash is then composed of the lines containing the InnerHash, the Nonce, and the bottom signature. Since the InnerHash is included in Block hash, it serves as a compact identifier for the entire block.

    $ ./hash_message.py

Paste the raw message below, (ie: InnerHash,Nonce + sig), then hit <Ctrl-D>
InnerHash: 64B858824682AB9D046F31DDACF7524FCD2501AEF269EE09E95EF2414DC9F7DB
Nonce: 10100000025565

    Transaction documents are also hashed so that they can be identified when being spent in future transactions; referred to as input source identifiers.

    example from Block #376477)
