lesson 2:
Anchor It On Chain

Put the hash in a data (OP_RETURN) output. The block's time then shows the file existed by that moment:

ammocoin-cli sendopreturn "<your_A_address>" "<sha256_hash>"
ammocoin-cli getrawtransaction "<txid>" 1

Look fer the output of type nulldata; yer hash is right there. The A address pays a small network fee. Rules from the code: one data output per transaction, and its script tops out at 83 bytes countin' the opcodes, so about 80 bytes of data. A 32-byte hash fits easy.

Safety: Never share yer private keys, seed phrase or wallet file with anybody. GLiBz never asks fer 'em, and neither does the QuarterMaster.
