# CelestiaBridge RPC and network details

Source: https://www.alchemy.com/rpc/celestiabridge

CelestiaBridge refers to the bridge-node layer that connects Celestia’s consensus network with its data-availability network. These nodes relay block data, verify that it’s available, and expose it to rollups that use Celestia as their DA layer. In practice, this is the infrastructure that lets modular L2s post data to Celestia and still be verifiable by light clients, the plumbing that makes “modular blockchains” actually work.
