40 sats \ 5 replies \ @pycan 1 Jul \ on: Analysis of 0xB10C's weird bitcoin transaction bitcoin
I've recently started studying https://learnmeabitcoin.com/ and on multiple places Greg mentions that non-standard aspects of a transaction (which this one obviously has) causes the transaction to not be relayed by the nodes. Can anyone clarify how did it get into the block, then? Could have it been placed there manually and, therefore, point to the Braiins pool?
Can anyone clarify how did it get into the block, then?
In the past I've gotten nonstandard transactions mined by emailing a miner and asking nicely. A lot of them have contact info in the footers of their websites, and bitcoin core has an RPC method for "injecting" a valid transaction directly into a block you're mining even if that transaction is non-standard. A few pools also have web apis for submitting non-standard transactions to them as long as you pay a high fee. I don't know if Braiins pool has such an api, but if they don't he probably emailed the transaction to them and asked nicely, or maybe the tx author works for them. I can confirm the tx was mined by Braiins -- the block it's in has a signature that includes Braiins's name.

the transaction is actually completely standard, and in fact was observed in mempool.space's mempool before it was mined.

Then that is perhaps the most fascinating thing about this transaction

Yes. The fact that this transaction made it into block 850000 (definitely not an accident) also suggests that it is completely standard. It would have been very risky to ask nicely of every major miner and risk that 850000 got mined by someone else.
