What is Layer 0 in Blockchain?. Layer 0 refers to the foundational networking and interoperability layer that connects multiple blockchains or secures them with shared validators.
How it works
Frameworks coordinate consensus, message passing, and security so new chains can launch more easily and communicate from day one.
Why it matters
Layer 0s aim to reduce fragmentation and bootstrap ecosystems faster.
Common pitfalls
- Confusing brand marketing with technical guarantees
- Ignoring shared‑security assumptions
- Overlooking validator incentives
Quick example
A project launches an application‑specific chain that inherits security from a Layer 0 hub.
