+ZetaChain is designed to have two types of validators: observers and signers.
+Observers monitor activities on connected chains, while signers handle the
+signing of transactions from the Threshold Signature Scheme (TSS) address on
+behalf of the protocol. However, currently, all observer-signer validators on
+ZetaChain perform both roles, acting as both observers and signers. This means
+each observer-signer validator simultaneously observes transactions on connected
+chains and participates in transaction signing.

 As they perform a critical function in the system, the minimum self
-delegation/stake required to be an observer is set as a param of the `observer`
-module on a per chain basis. This is to ensure that observers are incentivized
-to perform their duties and are not malicious.
