Polygon
EVM sidechain with ~100 validators and Ethereum checkpoints. Preliminary profile — full four-pillar audit pending.
Polygon PoS at a Glance
| Metric | Value |
|---|---|
| Type | EVM sidechain (Ethereum-anchored checkpoints) |
| Consensus | Proof of stake, ~100 validators |
| Token | POL (migrated from MATIC) |
| Launched | 2020 (as Matic Network) |
| Audit status | Preliminary profile — full four-pillar score pending |
Thesis: “The people’s sidechain — enormous usage on a modest validator set, secured by checkpoints rather than Ethereum execution.” This is a preliminary profile, not a scored audit — no composite score is assigned until independent measurement is complete.
Consensus & Architecture
Polygon PoS runs its own validator set producing fast, cheap blocks, with periodic checkpoints committed to Ethereum. Critically, it does not inherit Ethereum’s security the way a rollup does — a supermajority of its own validators could rewrite history regardless of Ethereum. That makes validator-set quality the entire security story.
Tokenomics
MATIC migrated to POL (1:1) as the ecosystem token for gas, staking, and the broader AggLayer vision. Large early allocations and foundation holdings shape ownership concentration — standard for 2020-era launches, and permanently on-chain for analysts to inspect.
Ecosystem
Historically the default cheap-EVM destination: DeFi majors, gaming, NFTs, and enterprise pilots (Starbucks, Reddit avatars) all ran here. Activity has partly migrated to L2s, but the chain remains among the most-used EVM networks by transaction count.
Risks
- Small validator set security: ~100 validators is orders of magnitude fewer than Ethereum — collusion and coercion thresholds are correspondingly lower.
- Checkpoint dependence: security ultimately rests on validator honesty, not Ethereum execution.
- Multisig/admin controls: upgrade keys and bridge contracts concentrate emergency power.
Audit Status: Preliminary
W3D has not yet published four-pillar scores for Polygon PoS. Validator independence, stake distribution, and upgrade-key structure are the measurements that matter most. Until measured, treat third-party grades as provisional.
