# Consensus Mechanism
|
|
Understand AITBC's proof-of-authority consensus mechanism.
|
|
|
|
## Overview
|
|
|
|
AITBC uses a Proof-of-Authority (PoA) consensus mechanism with:
|
|
- Fixed block time: 2 seconds
|
|
- Authority set of validated proposers
|
|
- Transaction finality on each block
|
|
|
|
## Block Production
|
|
|
|
### Proposer Selection
|
|
|
|
Proposers take turns producing blocks in a round-robin fashion. Each proposer gets a fixed time slot.
|
|
|
|
### Block Structure
|
|
|
|
```json
|
|
{
|
|
"header": {
|
|
"height": 100,
|
|
"timestamp": "2026-02-13T10:00:00Z",
|
|
"proposer": "ait-devnet-proposer-1",
|
|
"parent_hash": "0xabc123...",
|
|
"state_root": "0xdef456...",
|
|
"tx_root": "0xghi789..."
|
|
},
|
|
"transactions": [...],
|
|
"receipts": [...]
|
|
}
|
|
```
|
|
|
|
## Consensus Rules
|
|
|
|
1. **Block Time**: 2 seconds minimum
|
|
2. **Block Size**: 1 MB maximum
|
|
3. **Transactions**: 500 maximum per block
|
|
4. **Fee**: Minimum 0 (configurable)
|
|
|
|
## Validator Requirements
|
|
|
|
| Requirement | Value |
|
|
|-------------|-------|
|
|
| Uptime | 99% minimum |
|
|
| Latency | < 100ms to peers |
|
|
| Stake | 1000 AITBC |
|
|
|
|
## Fork Selection
|
|
|
|
Longest chain rule applies:
|
|
- Validators always extend the longest known chain
|
|
- Reorgs occur only on conflicting blocks within the last 10 blocks
|
|
|
|
## Finality
|
|
|
|
Blocks are considered final after:
|
|
- 1 confirmation for normal transactions
|
|
- 3 confirmations for high-value transactions
|
