Polygon zkEVM at a Glance
| Metric | Value |
|---|---|
| Type | Ethereum Layer 2 (rollup/">ZK rollup, EVM-equivalent) |
| Security | Zero-knowledge validity proofs settled on Ethereum |
| Compatibility | Deploy Ethereum contracts unchanged |
| Launched | 2023 (mainnet beta) |
| Audit status | Preliminary profile — full four-pillar score pending |
Thesis: “Strongest cryptographic guarantees in scaling, operated training wheels — validity is trustless, liveness isn’t yet.” This is a preliminary profile, not a scored audit — no composite score is assigned until independent measurement is complete.
Consensus & Architecture
Batches execute off-chain; succinct ZK proofs attest correctness; Ethereum verifies cheaply and finalizes in minutes — no week-long challenge windows. EVM equivalence means the full Ethereum toolchain works unmodified, the lowest migration friction in the ZK space.
Tokenomics
No dedicated gas token dynamics dominate (fees in ETH); the economic story is Polygon’s broader ecosystem (POL) funding proving infrastructure. Operator economics — who pays for proving — shape centralization more than any token schedule here.
Ecosystem
DeFi deployments ported from mainnet, payments experiments, and developers choosing cryptographic finality over optimistic dispute games. Activity remains smaller than optimistic leaders — the market currently prices EVM-liquidity-network-effects above proof strength.
Risks
- Operator centralization: sequencer and prover run by Polygon Labs today; validity guarantees hold, liveness/censorship depend on the operator.
- Proving economics: expensive proving concentrates future prover markets if decentralized proving stalls.
- Upgrade keys: admin-controlled upgrades can change rules faster than users can exit.
Audit Status: Preliminary
W3D has not yet published four-pillar scores for Polygon zkEVM. Operator independence and upgrade-key distribution are the key measurements. Until measured, treat third-party grades as provisional.
