Inside the Most Divisive Debate in Bitcoin Right Now
Natalie Brunell1h 10mAug 7, 2026
Watch the originalBIP-110 mandatory miner signaling triggered August 8th, creating a potential chain split where miners on different consensus rules produce competing blockchains — self-custody now so exchanges can't choose your chain for you.
Key takeaways
BIP-110 chain split risk is real and imminent — mandatory signaling triggers August 8th
BIP-110 chain split risk is real and imminent — mandatory signaling triggers August 8th
- BIP-110 nodes running Knots will reject blocks lacking miner signal starting ~Aug 8, potentially creating two competing chains.
- Miner signaling for BIP-110 is currently only 1-2%, meaning most hash power has not committed to the new consensus rules.

- Miners must wait 100 blocks to collect rewards; if BIP-110 chain ever exceeds legacy chain length, it orphans those blocks.
- This creates prisoner's dilemma game theory: first miner to switch to BIP-110 chain locks in rewards; last one on legacy chain loses them.
Bitcoin Core's OpReturn expansion from 80 bytes to 100,000 bytes is the root attack vector, not a minor policy tweak

- 80 bytes fits roughly an emoji; 100,000 bytes fits MP4 files and large images — a qualitative shift in what can be permanently embedded.
- Once data is mined into a block it cannot be removed; node runners must download and store it indefinitely or render their node unusable.
