Understanding Zero-Knowledge Technology
How zkEVM Processes Transactions
Transaction Submission
Users submit transactions to the zkEVM sequencer, which batches them for efficient processing.
Execution & Proof Generation
The zkEVM executes transactions and generates zero-knowledge proofs proving correct computation.
Batch Submission
Transaction batches and their validity proofs are submitted to Ethereum mainnet for final settlement.
Cryptographic Verification
Ethereum verifies the zero-knowledge proof, confirming all transactions in the batch are valid.
Instant Finality
Once verified on Ethereum, transactions achieve irreversible finality with mathematical certainty.

How does Proof of Efficiency secure the zkEVM network?
Polygon zkEVM introduces Proof of Efficiency (PoE), a novel consensus mechanism that incentivizes participants to generate zero-knowledge proofs efficiently while maintaining decentralization and security.
Proof of Efficiency Architecture
Decentralized Sequencing
Multiple sequencers compete to batch transactions efficiently, preventing censorship and ensuring fair transaction ordering.
Competitive Proving
Validators compete to generate zero-knowledge proofs, optimizing for both speed and cost efficiency.
Economic Incentives
MATIC rewards align participant incentives with network health, security, and performance optimization.
Ethereum Settlement
Final settlement on Ethereum mainnet provides ultimate security and dispute resolution.
Network Participant Roles
Economic Security Model
- Validator Staking: Minimum MATIC stake required for validation
- Sequencer Bonds: Economic guarantees for honest transaction batching
- Slashing Conditions: Penalties for malicious behavior or invalid proofs
- Delegation Support: MATIC holders can delegate stake to validators
- Transaction Fees: Distributed to sequencers and aggregators
- Block Rewards: MATIC rewards for proof generation and validation
- Efficiency Bonuses: Extra rewards for faster proof generation
- Staking Yields: 4-8% annual returns for MATIC stakers
- Cryptographic Finality: Mathematical proof of transaction validity
- Ethereum Settlement: Ultimate security from Ethereum mainnet
- Economic Security: Billions in staked MATIC securing the network
- Decentralized Validation: No single point of failure or control
Integration with Ethereum Mainnet
