Title: Re: Using brainwallets for proof of existence Post by: hexafraction on July 29, 2015, 07:39:08 PM There are a few issues in your logic:
1. OP_RETURN is limited, but a private key for a brainwallet is limited as well. Both involve hashing the data anyway. 2. OP_RETURN doesn't cause outputs to enter the UTXO, since they're not spendable by definition. 3. OP_RETURN could be made simpler to use by adding functionality to a wallet program, or by providing the user with a raw txn to sign using their own client.

I have wondered if something like this was possible before, I didn't know someone had already implemented it. |
