Safestake implements its operator software based on Hotstuff and Lighthouse validator client.

Hotstuff

Our code under the hotstuff directory is mostly taken from the Hotstuff repository, with the following modification:

• Upgrade to support port reuse for multiple committees (VAs)

• Optimize recovery and syncrhonization mechanisms after node crash and reboot

Lighthouse

Our operator is a modified decentralized version of Lighhouse's validator client. It reuses most of Lighthouse's VA logics, including:

• Duty retrieval and execution

• Slashing protection

The most important updates we make are:

• Update the signing method to include an option to sign distributely among a committee of operators

• Update the VA load and save logics to handle operators instead of complete validators.
