Eigen Layer
The Nodes might be run by external companies (Operators) that specialize in hosting such software, and fulfill hardware requirements.
Eigen Layer allows to reward Operators when host the service, and act honestly. Also allows to slash otherwise.
Operators put a stake on Silent Network AVS contract and commit to act honestly while providing the service. Silence Laboratories provides mechanism that detects if any of them is acting dishonest. EigenLayer allows to slash Operators funds (i.e. take their stake) if such event occurs.
The slashing/rewarding mechanism brings economic security. The stake the Operators put as collateral should be big enough to discourage any dishonest behavior. Ideally, the whole network economic security should be bigger than the digital assets it secures.
