FULL-STACK INFRASTRUCTURE
Custom Blockchain Development
End-to-end blockchain solutions from protocol design to mainnet deployment.
- Protocol Architecture: Design and implement custom consensus (
PoS,PoA,BFT) and execution layers. - Smart Contract Suite: Develop core protocol logic, governance, and utility contracts in
Solidity,Rust, orMove. - Node Infrastructure: Deploy and manage validator nodes, RPC endpoints, and block explorers.
- Cross-Chain Integration: Enable interoperability with bridges and messaging layers like
AxelarorLayerZero.
We deliver a fully audited, production-ready chain in 8-12 weeks, complete with documentation and dev tooling.

TANGIBLE RESULTS
Business Outcomes of a Dedicated Verification Parachain
A dedicated Substrate parachain for cross-chain archive validation delivers specific, measurable advantages over shared infrastructure. Here’s what you can expect when you build with Chainscore.
01
Unmatched Data Integrity & Finality
We deliver a sovereign, purpose-built chain with its own validator set, ensuring cryptographic proof of historical state is immutable and finalized in seconds. Eliminates reliance on third-party oracle consensus.
Sub-6 sec
Block Finality
100%
Data Availability
02
Reduced Operational Complexity & Cost
Our managed parachain solution abstracts away the complexity of collator operations, XCM configuration, and runtime upgrades. You get a production-ready validation service without the DevOps overhead.

Frequently Asked Questions
Get clear, specific answers about our Substrate parachain development process, timelines, and security for cross-chain archive validation.
A standard parachain for cross-chain validation with core pallets (timestamp, balances, transaction fees) takes 6-8 weeks from kickoff to Kusama/Polkadot auction readiness. Complex integrations with custom consensus or advanced XCM channels extend this to 10-14 weeks. We provide a detailed week-by-week roadmap after the initial architecture review.
