Proof Of Aggregation (PoAgg)

Overview​

Proof of Aggregation is LayerEdge's novel consensus mechanism that enables efficient proof verification and aggregation while maintaining security. The system combines traditional blockchain consensus with specialized proof handling capabilities.

Core Components​

1. Validator Network​

  • Validators stake $EDGEN tokens to participate
  • Responsible for block production and validation
  • Verify proofs at leaf level before aggregation
  • Participate in consensus for block finalization

2. Block Production Process​

  • Validators validate consecutive blocks (#n, #n+1, etc.)
  • Each block contains aggregated proofs from multiple sources
  • Validators receive rewards for:
    • Block validation
    • Proof verification
    • Participation in consensus

3. Proof Aggregation Layer​

The proof aggregation process occurs in three distinct phases:

Phase 1: Pre-aggregation Storage​

  • Individual proofs are received from various sources
  • Proofs are securely stored in a pre-aggregation layer
  • Initial validation checks are performed

Phase 2: Leaf-level Verification​

  • Validators perform detailed verification of individual proofs
  • Each proof is checked for validity before aggregation
  • Failed proofs are rejected at this stage

Phase 3: Proof Aggregation​

  • Valid proofs enter the aggregation sequencer
  • Multiple proofs are combined efficiently
  • Final aggregated proof is produced
  • Aggregated proof is settled on Layer 1 (Bitcoin)

Validator Rewards​

Validators receive rewards from multiple sources:

  1. Block production rewards
  2. Proof verification rewards
  3. Aggregation participation rewards

Security Model​

Staking​

  • Validators must stake $EDGEN tokens
  • Stake serves as security deposit
  • Slashing conditions for malicious behavior

Verification​

  • Multi-level verification process
  • Leaf-level proof checking
  • Aggregate proof validation
  • Cross-validation among validators

Settlement Process​

  1. Final aggregated proof is generated
  2. Proof is verified by validator network
  3. Settlement transaction is prepared
  4. Proof is posted to Layer 1 (Bitcoin)

Network Benefits​

  1. Cost Efficiency

    • Shared verification costs
    • Reduced settlement expenses
    • Efficient resource utilization

  2. Security

    • Multi-layer validation
    • Economic incentives for honest behavior
    • Robust slashing conditions

  3. Scalability

    • Parallel proof processing
    • Efficient aggregation
    • Optimized settlement
