Abstract
Bitcoin has no formal process for evaluating proposed changes to its consensus rules. The BIP system provides a mechanism for proposing changes, but establishes no minimum standards that a proposal must meet before the community considers activation. There are no required review periods, no mandatory code audit standards, no agreed-upon activation thresholds, no chain split risk assessment methodology, and no framework for evaluating the legal and economic consequences of a failed activation.
This paper proposes a comprehensive framework for evaluating Bitcoin consensus change proposals. It draws on the history of Bitcoin's prior consensus changes, established principles of software engineering governance, and legal analysis of the liabilities created by reckless activation. The framework includes a 20-point Consensus Change Readiness Checklist covering proposal quality, code quality, activation safety, and community process.
Key Contributions
The framework establishes minimum standards across four areas:
- Proposal Requirements — Problem statement, technical specification, backward compatibility analysis, activation mechanism, rollback procedure, and reference implementation.
- Minimum Review Periods — 12 months for moderate-risk consensus changes; 24 months for high-risk changes that invalidate currently valid transaction types.
- Code Audit Standards — Independent review by three developers, comprehensive test coverage, three-month testnet deployment, fuzzing, and AI-code disclosure requirements.
- Activation Thresholds — Minimum 90% for miner-activated soft forks. Thresholds below 60% are classified as reckless.
The paper includes a detailed case study of BIP-110 (scoring 4/20 on the proposed checklist) and a legal analysis covering negligence, tortious interference, fiduciary duties, and regulatory implications of chain splits.
