Attestor Role
Section titled “Attestor Role”Attestors have two main roles:
- Following and attesting to source-chain blocks. Attestors follow new blocks on a source chain and attest to them. This is done eagerly, and enables inexpensive and rapid readability of source-chain data.
- Signing writability messages (not yet released). In an upcoming release, Attestors will also sign writability messages. This will enable Universal Smart Contracts to send data to a destination chain, effectively providing full two-way interoperability.
