Validators

The operations of a Validator involve two roles:

Validator

In exSat, there is a group of Validators responsible for reaching consensus on the BTC block hashes to ensure the imported BTC block data is correct. Each Validator independently obtains the BTC block hash and submits it to exSat. Consensus on the current block hash is achieved when the block hash submitted by more than two-thirds of the Validators matches. Validators must stake at least 100 BTC to participate in the consensus.

Validators can stake for themselves as Stakers or accept stakes from other Stakers. Validators can set a commission rate; the commission portion of the rewards goes to the Validator, while the remaining rewards go to the Stakers who staked for the validator.

Validators need to obtain the BTC block hash from reliable sources, such as running their own BTC node; They also need to run the Validator client to submit the block hash to the exSat network.

Staker

Everyone who holds BTC can be a staker. Stakers can stake their BTC to a Validator to earn the XSAT staking rewards. Stakers can view the validators on this page and choose one to stake. Stakers can claim rewards on this page. Stakers do not need to run the Validator Client themselves, the XSAT rewards comes from the validator he/she staked to, so when selecting a Validator, consider factors like the commission rate and operational stability.
