Coinbase’s Ethereum Layer 2, Base to Upgrade to Zero-Knowledge Proofs via SP1

Share:
Base, the Coinbase‑incubated Ethereum Layer‑2, is migrating from optimistic rollups to a zero‑knowledge architecture that combines a trusted execution environment (TEE) with zk proofs to secure chain finality; the network currently holds about $12B in total capital (TVL). The upgrade aims to improve security and finality, which is likely positive for DeFi adoption, DEX/CEX liquidity and protocol activity on Base, while introducing new TEE trust assumptions and potential regulatory/security trade‑offs.
Base, the Coinbase-incubated Ethereum Layer 2 network, is upgrading its core architecture from optimistic rollups to a zero-knowledge-based system in a major shift in its security design.
The network, which currently holds around $12 billion in total capital, will adopt a trusted execution environment (TEE) combined with zero-knowledge proofs to secure chain finality.
