Phase 5, Milestone 2: Governance Features

Advanced governance capabilities

Status: ✅ Complete Priority: Medium Crates: synor-governance

---

Overview

Implement advanced governance features including parameter changes, protocol upgrades, emergency controls, and vesting management.

---

Tasks

Task 2.1: Parameter Change Proposals

• Define changeable parameters
• Parameter bounds validation
• Change execution logic
• Rollback capability
• Change history tracking

Files:

• crates/synor-governance/src/parameters.rs

Governable Parameters:

Parameter	Min	Max	Default
block_time_ms	50	2000	100
max_block_size	100KB	10MB	1MB
min_fee_rate	0	1000	1
k_parameter	8	64	18
pruning_depth	1000	100000	10000

Task 2.2: Protocol Upgrade Mechanism

• Upgrade proposal type
• Binary hash verification
• Activation height scheduling
• Soft fork support
• Hard fork coordination

Files:

• crates/synor-governance/src/upgrade.rs

Upgrade Process:

1. Proposal submitted with new version hash
2. Voting period (7 days)
3. If passed, queued with timelock (2 days)
4. Activation height set (future block)
5. Nodes upgrade before activation
6. Network activates new rules

Task 2.3: Emergency Pause Capability

• Emergency pause proposal
• Reduced timelock for emergencies
• Pause specific components
• Resume mechanism
• Guardian multi-sig fallback

Files:

• crates/synor-governance/src/emergency.rs

Emergency Actions:

Action	Timelock	Required Votes
Pause Mempool	1 hour	Guardian multi-sig
Pause Mining	1 hour	Guardian multi-sig
Pause Contracts	6 hours	10% quorum
Full Pause	12 hours	15% quorum

Task 2.4: Vesting Schedule Management

• Create vesting schedules
• Cliff period support
• Linear vesting calculation
• Early termination (governance)
• Vesting claims

Files:

• crates/synor-governance/src/vesting.rs

Vesting Parameters:

struct VestingSchedule {
    beneficiary: Address,
    total_amount: Amount,
    start_time: Timestamp,
    cliff_duration: Duration,
    vesting_duration: Duration,
    claimed: Amount,
}

Validation

Validation Commands

# Run all governance tests
cargo test -p synor-governance

# Test parameter changes
cargo test -p synor-governance parameters

# Test upgrades
cargo test -p synor-governance upgrade

# Test emergency
cargo test -p synor-governance emergency

# Test vesting
cargo test -p synor-governance vesting

Validation Agents

Agent	Purpose
code-reviewer	Review governance features
silent-failure-hunter	Check edge cases

Feature Test Matrix

Feature	Unit Tests	Integration Tests
Parameters	12	5
Upgrades	8	4
Emergency	10	6
Vesting	15	8

Security Checks

• Parameter bounds enforced
• Upgrade hashes verified
• Emergency powers limited
• Vesting cannot be front-run
• Guardian keys secure

Governance Attack Vectors

Attack	Mitigation
Flash loan voting	Snapshot-based voting power
Governance takeover	High proposal threshold
Malicious upgrade	Binary hash verification + timelock
Treasury drain	Spending limits + multi-sig

CLI Commands

# Parameter change
./target/release/synor gov propose param block_time_ms 200

# Protocol upgrade
./target/release/synor gov propose upgrade v2.0.0 <hash>

# Emergency pause
./target/release/synor gov propose emergency pause-contracts

# Vesting management
./target/release/synor gov vesting create <beneficiary> <amount> <duration>
./target/release/synor gov vesting claim

---

Acceptance Criteria

1. Parameter changes execute correctly
2. Upgrade proposals work end-to-end
3. Emergency pause functional
4. Vesting schedules manage correctly
5. All security checks implemented
