Observer-Signer Validators
ZetaChain has two types of validators: core validators and observer-signer validators (observer-signers).
Observer-signers are tasked with running nodes of connected chains, observing
them with zetaclient
and writing transactions to connected chains.
The protocol is designed in a way to allow observer-signers in the future to choose which chains they want to observe. This allows for a more flexible system where observer-signers can observe only the subset of chains they are interested in (for example, their infrastructure is built around running EVM nodes). In the current version of the protocol, all observers-signers are observing all chains.
A list of observer-signers on the ZetaChain testnet:
As they perform a critical function in the system, the minimum self
delegation/stake required to be an observer-signer is set as a param of the
observer
module on a per chain basis. This is to ensure that observer-signer
validators are incentivized to perform their duties and are not malicious.
