Ethereum co-founder Vitalik Buterin has outlined a long-term vision for the network that moves beyond its foundational blockchain architecture. In an essay published Sept. 27, he describes how modern cryptography could enable participants to divide computational work without requiring every node to repeat calculations.
Buterin characterized Ethereum's transformation in stark terms. "It's really not just a blockchain anymore," he wrote, noting that verification, privacy, and processing would increasingly depend on cryptographic tools and decentralized infrastructure rather than traditional blockchain mechanisms.
Replacing Full Verification With Cryptographic Proofs
Buterin explained that Ethereum's current model requires network participants to download blocks and repeat calculations to validate transactions. His proposed architecture would instead use cryptographic proofs and data sampling to verify that calculations were performed correctly.
He attributed past challenges in this approach to verification reliability. "Back then, this was not viable for one primary reason: the missing ingredient was verification," Buterin wrote. He argues that advances in cryptography have now supplied that missing component, enabling the network to process more work simultaneously while distributing tasks among participants who do not automatically trust one another.
Developer Incentives and Application Design
Under the proposed architecture, developers would face different economic incentives for how they structure applications. Those designing applications into separable tasks that can proceed simultaneously or be processed outside blocks would face lower costs than applications bundling everything into sequential transactions.
"When building applications, structure of computation is starting to matter a lot," Buterin noted. The chain would focus on changes requiring shared ordering, while surrounding infrastructure handles supporting work.
2030 Vision and Network Capabilities
Buterin's 2030 comparison sketches transaction finality at roughly eight to 32 seconds, along with stronger transaction-inclusion guarantees, enhanced privacy, and lighter node requirements. He emphasized these represent a future design rather than currently available capabilities.
Hegota as the Final 'Normal' Fork
Buterin identified Ethereum's Hegota upgrade, planned for 2027, as likely the network's last "normal" fork—one whose technology would resemble familiar blockchain development. Subsequent changes would center on advanced proofs, formal verification, and optimized consensus mechanisms.
Buterin noted remaining engineering challenges, including achieving sufficient efficiency and safety in proofs while managing access to large amounts of stored application information. He presented obfuscation, a cryptographic technique supporting encrypted computation, as a longer-term possibility rather than a near-term requirement.
Buterin drew a distinction regarding network speed, stating that "Ethereum itself will never have latency that competes with servers, but infrastructure built around it could."
