STRATEGIC ADVISORY

Blockchain Infrastructure Consulting

Strategic guidance to architect, select, and scale your Web3 infrastructure for long-term success.

We provide architecture reviews and technology selection to de-risk your infrastructure decisions. Our experts analyze your use case to recommend the optimal L1/L2, data availability layer, and node provider mix, balancing cost, performance, and decentralization.

  • Proof-of-Concept Validation: Stress-test your architecture with load testing and cost modeling before major investment.
  • Migration Planning: Structured roadmaps for moving between chains (e.g., Ethereum to Arbitrum) or upgrading core systems.
  • Vendor & Tool Evaluation: Objective analysis of RPC providers, oracles, and indexers against your specific requirements.

We translate complex trade-offs into clear, actionable roadmaps, ensuring your technical foundation supports business growth without costly re-architecture.

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.

FeaturePolygon SupernetsAvalanche SubnetsChainscore 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

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.
