The Verifier’s Dilemma describes a situation in blockchain networks where verifiers, typically full nodes, are incentivized to skip computationally expensive verification of transactions or proofs to save resources. A Verifier’s Dilemma solution provides mechanisms to ensure that verifiers perform their duties honestly, often through economic incentives or cryptographic guarantees, without centralizing trust. It aims to maintain the integrity of the network.
Context
Addressing the Verifier’s Dilemma is crucial for the security and decentralization of scaling solutions like optimistic rollups, where verifiers are responsible for detecting fraudulent transactions. Solutions often involve fraud proofs and economic penalties for dishonest behavior, alongside rewards for diligent verification. The ongoing development of robust solutions is key to the long-term viability and trustlessness of Layer 2 scaling.
