Ankr runs centralized multichain RPC with a staking layer bolted on. MeterCall runs decentralized nodes first, with stake, slashing, and bridge attestations as primitives.
| Dimension | MeterCall L4 | Ankr |
|---|---|---|
| Node model | Permissionless, community-run, staked | Primarily Ankr-operated infra + a staking-as-a-service layer |
| Decentralization | True DePIN — anyone runs, anyone earns | Centralized RPC with optional validator staking |
| Pricing model | Pay-per-call in PCP or USD, metered | Free public tier + paid "Premium" subscription + Protocol API rate tiers |
| Chains | 30+ via upstream config (including Ankr itself as an upstream) | 50+ chains, very broad |
| Real-world APIs | 20M+ APIs unified under one billing pipe | Not offered |
| Bridge | Yes — nodes sign attestations, earn per message | Not a primary product |
| Token | PCP — native to serving + staking | ANKR — governance + some staking |
| Operator revenue | Per-call rewards, paid every epoch | Validator staking rewards only (if operating a chain's validator, not Ankr RPC) |
| Slashing for bad answers | 1%/10%/100% based on verified dishonest answers | N/A — Ankr serves centrally, trust assumed |
| Open source | Node + contracts MIT | Some components open, core infra closed |
