There are a bunch of encoded messages in the first taproot enabled block in op_return outputs. What is encoded there?

  • I'm a bit confused at the mention of the the Genesis Block here. The Genesis Block is the zeroth block of the Bitcoin blockchain. The first Taproot-enabled block doesn't have anything to do with the Genesis block.

  • I see. Sorry wrong use of the word genesis then. I was under the impression the first activated block of Taproot was also called a genesis block! Commented Nov 16, 2021 at 15:33

I don't know so alternative answers are welcome!

If you look at the coinbase transaction in the block 709632 (mined by F2Pool) where full nodes started enforcing Taproot rules there is a scriptSig and 4 OP_RETURNs.

The scriptSig is:

OP_PUSHBYTES_3 00d40a OP_PUSHBYTES_44 fabe6d6db2182a1a8634a5b5c8e4c9102f69b795db3d02e80064a0b007408cca80f68dc110000000f09f909f OP_PUSHBYTES_8 2f4632506f6f6c2f OP_0 OP_0 OP_0 OP_0 OP_0 OP_0 OP_0 OP_0 OP_0 OP_0 OP_0 OP_0 OP_0 OP_0 OP_0 OP_0 OP_0 OP_0 OP_0 OP_0 OP_0 OP_0 OP_0 OP_0 OP_0 OP_0 OP_0 OP_0 OP_0 OP_0 OP_0 OP_0 OP_0 OP_0 OP_0 OP_0 OP_PUSHBYTES_5 00de920100

I don't know what the messages are in the OP_RETURNs though one of the OP_RETURNs is presumably used for the RSK sidechain as it refers to RSKBLOCK.
