Overview
Layer 0 refers to the foundational infrastructure beneath individual blockchain networks. These protocols enable cross-chain communication, message passing, and interoperability — solving the problem of isolated blockchains that cannot natively communicate with each other.
Key Protocols
- Layer 0 Networks — Overview of cross-chain infrastructure protocols
- Inter-Blockchain Communication Protocol (IBC) — Cosmos ecosystem’s protocol for blockchain interoperability
- Mixin Network — A layer-0 network for inter-chain asset transfer and high-speed transactions
- Nostr — Simple, censorship-resistant communication protocol using cryptographic keys
