Technical Comparison
Polygon Supernets vs. Avalanche Subnets: Choosing Your Foundation
Key architectural and operational differences between the two leading appchain platforms for custom event ecosystems.
| Feature | Polygon Supernets | Avalanche Subnets | Chainscore Recommendation |
|---|---|---|---|
Architecture | ZK L2 anchored to Ethereum | Primary Network (P-Chain) validated subnet | Depends on EVM affinity vs. custom VM needs |
Consensus Model | PoS with Polygon Edge validators | Avalanche consensus (Snowman++) | Avalanche for speed, Polygon for Ethereum alignment |
Time to Deploy (Typical) | 8-12 weeks | 6-10 weeks | Chainscore delivers in 4-8 weeks for both |
Gas Token Model | Native MATIC or custom token | Subnet-specific gas token (flexible) | Custom token preferred for economic control |
Cross-Chain Messaging | Native Ethereum bridge (POS), CCTP | Avalanche Warp Messaging (AWM) | AWM is simpler; Polygon bridges are more battle-tested |
EVM Compatibility | Full EVM equivalence | EVM via C-Chain or custom VM | Polygon for pure EVM, Avalanche for VM flexibility |
Validator Requirements | 5+ independent validators recommended | Minimum 1 validator (less decentralized) | We manage validator orchestration for both |
Typical TPS for Event Apps | 2,000 - 7,000+ | 4,500 - 10,000+ | Avalanche for ultra-high throughput events |
Security Audit Necessity | Critical (public chain bridge) | Critical (custom VM) / High (EVM) | Full audit included in our development package |

AppChain Event Ecosystems
Frequently Asked Questions
Common questions from CTOs and founders about building custom event-driven architectures on dedicated blockchains.
An AppChain Custom Event Ecosystem is a dedicated blockchain (AppChain) designed with a native event-driven architecture. Unlike generic L2s, we build a custom execution environment where smart contracts emit and listen for specific, high-throughput events (e.g., trade execution, oracle updates, cross-chain messages). This enables sub-second finality for event processing, predictable gas costs, and a data model optimized for your application's logic, resulting in a 10-100x performance improvement over deploying on a shared network.
