TL;DR:

EIP-X proposes a solution to Ethereum's statelessness problem by integrating zero-knowledge proofs (ZKPs) into the light client framework. This enables validators to provide concise proof of their staking activities, reducing computational burdens and enabling efficient restaking at scale. By addressing the challenges of penalizing validators for invalid blocks, EIP-X enhances network security and scalability, promising a brighter future for Ethereum's ecosystem.
