Buterin outlines Ethereum's future as a cryptography-driven world computer

Vitalik Buterin published a blog post describing Ethereum's evolution into a world computer secured by cryptography, combining blockchain consensus with privacy layers and off-chain computation. He expects the network by 2030 to offer adjustable computation scale, lower node requirements, and privacy built into the protocol. The Hegota fork planned for 2027 may be the last upgrade recognizable to those familiar with Ethereum circa 2015, with later changes focusing on recursive STARKs, formal verification, and quantum safety.

Buterin’s September 27 post describes Ethereum becoming a globally shared computer secured by cryptography, combining consensus with zero-knowledge proofs, privacy features, and computation performed away from the main chain. He predicts that by 2030 users could tune computational capacity, run lighter nodes, and rely on protocol-level privacy.

The planned 2027 Hegota fork may be the final upgrade that veterans of Ethereum’s mid-2010s design would recognize. Afterward, Buterin points to recursive STARKs, formal verification, quantum resistance, and stronger zero-knowledge support. He also proposes a “walkaway test”: apps should survive if their original developers vanish. Recent gains include higher gas limits, more blob space, and zkEVM advances.
