# Asterizm Relayer

Asterizm or [partner servers](/guides/external-relays.md) that act as a transport layer. 

These servers transfer proofs of cross-chain transactions (hash + unique ID) from one network to another without any consensus between them but with rules on waiting for the right number of blocks to validate the transaction in each supported network, which significantly speeds up cross-chain transactions.
