FAQs

FAQs About Layer 0 Blockchain Development

Layer 0 refers to the foundational infrastructure that enables multiple blockchains (Layer 1s) to interconnect, share security, and exchange data or tokens.

Layer 0 connects and supports multiple Layer 1 chains, unlike Layer 1s (e.g., Ethereum) that host applications, or Layer 2s (e.g., rollups) that scale them.

You can build relay chains (like Polkadot), hubs (like Cosmos), appchain ecosystems, modular chains, or crosschain DeFi and governance tools.

Timelines vary by scope, but a basic Layer 0 prototype typically takes 10–14 weeks. Production networks with validators and tooling take 4–6+ months.

Yes. We support interchain messaging standards like IBC (Cosmos), XCM (Polkadot), or design proprietary messaging systems.

Yes. We help you implement or modify consensus algorithms like PoS, BFT, or custom hybrid coin logic tailored to your ecosystem needs.

Absolutely. We configure validator nodes, launch staking dashboards, CLI tools, and governance portals.

We offer maintenance, scaling strategies, SDK support, security patches, and continuous protocol upgrades tied to your roadmap.
