Farside Insights said miners marked as supporting BIP-110 are using out-of-band relay networks to include non-standard spam transactions in the blocks they mine. The account cited two suspect transactions, sized 10KB and 38.5KB, both mined by Roughnecks, the dominant BIP-110 miner at present. It also said the transactions did not appear on mempool.space or in expected block templates, and were flagged as “extra transactions” on miningpool.observer, which is run by @0xB10C. Farside Insights said it backtracked the blocks with bitcoin-cli’s invalidateblock command and ran testmempoolaccept on the transactions, with both returning disallowed. On that basis, the account said the transactions were non-standard and were not relayed normally under Bitcoin Core rules. It added that a person inside Roughnecks’ pool who is unhappy with the BIP-110 stance may be using an out-of-band relay system to insert the transactions into blocks.

The account cited two suspect transactions, sized 10KB and 38.5KB, both mined by Roughnecks, the dominant BIP-110 miner at present. It said neither transaction appeared on mempool.space or in the expected block templates, and both were labeled “extra transactions” on miningpool.observer, a site run by @0xB10C.
Farside Insights said it rolled back the relevant blocks with bitcoin-cli’s invalidateblock command and tested the transactions with testmempoolaccept. Both tests returned disallowed, which led the account to describe the transactions as non-standard and not normally relayed under Bitcoin Core rules.
The account then speculated that someone inside the Roughnecks pool may be unhappy with the pool’s BIP-110 position and is using an out-of-band relay system to inject non-standard spam transactions into blocks.
