Hello everyone,

This is my first post here, so forgive me if this isn't in the right place.

I run a handful of Python scripts I wrote a couple of years ago from time to time to find unusually large outputs in single transactions. The most common thing that pops up is large OP_RETURN outputs, as people have recently been shoving more arbitrary data in these since Bitcoin Core raised the policy-imposed limit.

My script found this transaction, recently: 00000000000ad99639585eb5fb0dc0bb093575719ecd78cfede972637b65de07.

It contains the entire whitepaper in a single OP_RETURN output (vout=1).

The transaction itself is also funny, since the TXID has clearly been vanity-searched (there is a nonce in the last vout of the TX), the origin address has a small HASH160, and one of the output addresses starts with 1Bitcoin.... The SHA-256 hash of the PDF itself must also have been vanity-searched: 0000000000003c2287e2a94e93882e1f56fcbfa3c71c5b1c75edf11c6946e6cb.

Thought it could be interesting to highlight this.

Best regards,
