This block is weird: https://mempool.space/block/00000000000000000001c62110bb97a52bf3015ea3abd9b318c300e5c0fba791

It contains 7,812 transactions (giving a rate of 13 transactions per second, wow!) and almost every transaction in it has an op_return in it that merely says 14 01 14 00

That doesn't decode to anything I'm aware of

Thoughts?
