Matt Kratter: Inside Bitcoin's Civil War Over BIP-110
- BIP 110 fundamentals: A consensus change proposal that would restrict OP_RETURN data field sizes to prevent large non-monetary data (spam, NFTs, inscriptions) from being embedded in the Bitcoin blockchain.
- Node decentralization vs. mining pools: The core tension—whether individual node runners or large regulated mining pools determine Bitcoin's rules. Currently, five to six pools produce ~90% of blocks.
- Chain split risk: If miners do not signal BIP 110 support by mandatory signaling (scheduled for August 8), a permanent chain split is possible, mirroring the 2017 block size wars and resulting in two separate Bitcoin versions.
- Spam and CSAM concerns: Expanded OP_RETURN fields (80 bytes → 100,000 bytes) open the door to hosting child sexual abuse material and other illicit content permanently on-chain, making node operation legally and ethically problematic.
- UASF precedent: BIP 110 follows the User-Activated Soft Fork model used successfully in 2017 to activate Segwit against industry opposition; Kratter argues Bitcoin's "immune system" is working despite hostile rhetoric.
- Bitcoin University and Kratter's background: Founder transitioned from Stanford English PhD and hedge fund manager (Clarium Capital under Peter Thiel, 2003–2006) to Bitcoin educator after discovering Bitcoin in late 2019.
