On Sept. 27, Ethereum co-founder Vitalik Buterin published a new essay, "The cryptographic world computer," saying Ethereum could, over the next several years, evolve into a system that is architecturally distinct from a traditional blockchain.
Buterin outlines the next phase of Ethereum’s design
Buterin wrote that Ethereum already has general-purpose computation, proof-of-stake, zero-knowledge proofs, and Layer 2 scaling. The next stage, he said, would bring in a more adjustable computing architecture, multi-party block building, a highly optimized proof-of-stake model, and zero-knowledge proofs deeply integrated into the base layer.
Core mechanisms could change around 2030
He said that by around 2030, Ethereum’s core mechanisms for transaction verification, consensus, block construction, privacy, and computation could all change. That includes moving away from re-downloading and executing blocks, and toward SNARK verification and PeerDAS-based data availability verification; shifting from proof-of-work to a highly optimized proof-of-stake system; and replacing block construction by a single actor with block building involving multiple parties.
From ledger to cryptographic world computer
Buterin also said Ethereum’s decentralized network may eventually serve not only security and censorship resistance, but also performance gains through parallel storage, parallel computation, and privacy protection. He added that the Hegota upgrade may be Ethereum’s last "traditional" hard fork. After that, recursive STARKs, automated formal verification, optimized consensus mechanisms, and quantum-resistant technology could become the main areas of development, pushing Ethereum from a simple ledger toward a "cryptographic world computer" that combines blockchain, cryptographic privacy, verifiable computation, and decentralized off-chain components.
