Proof-of-Stake

ProofOfStake Class

utilities/proof_of_stake.py

The ProofOfStake class provides a reusable implementation of on-chain Proof-of-Stake (PoS) verification logic. It is designed to serve as a shared component across middleware layers and authorization modules that require peer stake validation.

This class is primarily utilized by the ProofOfStakeAuthorizer, but can also be integrated into other subsystems within the subnet framework. Standardizing PoS verification rules ensures consistency and persistence of stake logic throughout the network.

Key Features

• Reusable Middleware Component Can be embedded in any logic that requires verifying a peer’s on-chain PoS.

• Persistent State Management Maintains PoS-related state across the subnet, preventing redundant or excessive verification attempts.

• Cooldown Mechanism Enforces cooldown periods when one peer verifies another’s stake, mitigating the risk of over-verification during high request/response throughput.

Purpose

The ProofOfStake class allows multiple system components to rely on the same verification logic without duplication, ensuring that PoS validation is efficient, consistent, and resistant to abuse.
