SECTION 2: WHAT IS BLOCKCHAIN GOVERNANCE?
2.1 Definition
Blockchain governance is the system of rules, practices, and processes through which a blockchain project or protocol is directed, controlled, and evolved. It encompasses who has the authority to make decisions, how decisions are made, and how conflicts are resolved.
2.2 Why Governance Matters
┌─────────────────────────────────────────────────────────────────────────────┐ │ WHY GOVERNANCE MATTERS │ ├─────────────────────────────────────────────────────────────────────────────┤ │ │ │ ┌──────────────────────────────────────────────────────────────────────┐ │ │ │ PROTOCOL EVOLUTION │ │ │ │ How decisions are made about upgrades, changes, and improvements. │ │ │ │ • New features │ │ │ │ • Bug fixes │ │ │ │ • Parameter adjustments │ │ │ └──────────────────────────────────────────────────────────────────────┘ │ │ │ │ ┌──────────────────────────────────────────────────────────────────────┐ │ │ │ RESOURCE ALLOCATION │ │ │ │ How treasury funds and other resources are allocated. │ │ │ │ • Grants │ │ │ │ • Development funding │ │ │ │ • Marketing and partnerships │ │ │ └──────────────────────────────────────────────────────────────────────┘ │ │ │ │ ┌──────────────────────────────────────────────────────────────────────┐ │ │ │ CONFLICT RESOLUTION │ │ │ │ How disputes and disagreements are resolved. │ │ │ │ • Dispute resolution mechanisms │ │ │ │ • Fork avoidance │ │ │ │ • Community alignment │ │ │ └──────────────────────────────────────────────────────────────────────┘ │ │ │ │ ┌──────────────────────────────────────────────────────────────────────┐ │ │ │ STAKEHOLDER ALIGNMENT │ │ │ │ How different stakeholder interests are balanced. │ │ │ │ • Team vs community │ │ │ │ • Investors vs users │ │ │ │ • Short-term vs long-term │ │ │ └──────────────────────────────────────────────────────────────────────┘ │ │ │ └─────────────────────────────────────────────────────────────────────────────┘
SECTION 3: GOVERNANCE MODELS
3.1 Types of Governance
┌─────────────────────────────────────────────────────────────────────────────┐ │ GOVERNANCE MODELS │ ├─────────────────────────────────────────────────────────────────────────────┤ │ │ │ 1. OFF-CHAIN GOVERNANCE │ │ ┌──────────────────────────────────────────────────────────────────────┐ │ │ │ • Decisions made through social and community processes │ │ │ │ • Proposals discussed in forums, social media │ │ │ │ • Core team or foundation implements │ │ │ │ • Examples: Bitcoin, Ethereum (historically) │ │ │ │ • Pros: Flexible, low friction │ │ │ │ • Cons: Less transparent, slower │ │ │ └──────────────────────────────────────────────────────────────────────┘ │ │ │ │ 2.

Key parameters: proposal threshold, voting period, quorum, approval threshold, timelock. 6. Risks: whale dominance, voter apathy, sybil attacks, governance capture, forks. Selection Framework: - High decentralisation goal → On-Chain or DAO - Need speed → Off-Chain or Hybrid - Large community → On-Chain or DAO - Limited resources → Off-Chain - Enterprise use → Hybrid Recommendations: - Match governance model to project goals and community. - Implement clear proposal and voting processes. - Set appropriate quorum and thresholds. - Encourage participation through incentives. - Monitor for governance risks. - Be prepared to evolve governance over time.
