# 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
|
|
- [x] Define changeable parameters
|
|
- [x] Parameter bounds validation
|
|
- [x] Change execution logic
|
|
- [x] Rollback capability
|
|
- [x] 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
|
|
- [x] Upgrade proposal type
|
|
- [x] Binary hash verification
|
|
- [x] Activation height scheduling
|
|
- [x] Soft fork support
|
|
- [x] 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
|
|
- [x] Emergency pause proposal
|
|
- [x] Reduced timelock for emergencies
|
|
- [x] Pause specific components
|
|
- [x] Resume mechanism
|
|
- [x] 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
|
|
- [x] Create vesting schedules
|
|
- [x] Cliff period support
|
|
- [x] Linear vesting calculation
|
|
- [x] Early termination (governance)
|
|
- [x] Vesting claims
|
|
|
|
**Files:**
|
|
- `crates/synor-governance/src/vesting.rs`
|
|
|
|
**Vesting Parameters:**
|
|
```rust
|
|
struct VestingSchedule {
|
|
beneficiary: Address,
|
|
total_amount: Amount,
|
|
start_time: Timestamp,
|
|
cliff_duration: Duration,
|
|
vesting_duration: Duration,
|
|
claimed: Amount,
|
|
}
|
|
```
|
|

## Validation
|
|
|
|
### Validation Commands
|
|
|
|
```bash
|
|
# 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 |
|
|
|
