40バイトあればハッシュ値を保存するのには十分ですね。
ブロックチェインをどうやって新月プロトコルに組み込むか悩んでたんですけど、Bitcoinの馬尻に乗るなら行けそうな気がしてきました。

Explanation of what an OP_RETURN transaction looks like

To reach a middle ground in these opposing views, the core-developers made the opcode OP_RETURN a valid opcode to be used in a bitcoin transaction, which allows 80 arbitrary bytes to be used in an unspendable transaction. A good explanation of this can be found here:

Later in February 2014, the bytes count was reduced from 80 to 40 bytes. This change is documented in the link below. Note that in this pull discussion we learn that no more than one output with OP_RETURN can be included in a single transaction:
