Ethereum co-founder Vitalik Buterin has outlined a new vision for the network, describing an Ethereum that will eventually become more than a traditional blockchain and instead operate as what he calls a “cryptographic world computer.”
In a published blog post titled “The Cryptographic World Computer,” Buterin argued that Ethereum has evolved significantly since its launch and is heading toward a hybrid architecture that combines blockchain technology with modern cryptography.
“It’s really not just a blockchain anymore,” Buterin said while sharing the post, describing the future network as a system that combines blockchains and cryptographic technology to provide cheaper, more scalable and more private computation.
Ethereum’s architecture is changing
According to Buterin, several technologies already being developed or deployed on Ethereum are changing what the network can do.
These include zero-knowledge proofs, proof-of-stake, data sampling, privacy technologies and decentralised computation that can happen outside the blockchain while still being verified cryptographically.
One of the biggest changes is how Ethereum could handle computation. Instead of requiring every node to download and independently re-execute large amounts of data, future nodes could sample data and verify cryptographic proofs showing that the required computation was performed correctly.
Buterin pointed to PeerDAS as an early example of this direction. The technology, introduced with Ethereum’s Fusaka upgrade in December 2025, allows validators to sample data rather than downloading all of it. He expects similar techniques to eventually cover more of the network’s block contents.
The goal is to allow Ethereum to process more activity without simply increasing the amount of work every individual node must perform.
This could also improve privacy. Buterin expects zero-knowledge proofs to become more deeply integrated into Ethereum, allowing certain transactions and computations to be verified without exposing all of the underlying information.
Hegota could mark the end of Ethereum’s “normal” upgrades
Buterin also placed the planned Hegota upgrade at an important point on Ethereum’s roadmap.
Hegota, which is planned for 2027, is likely to be Ethereum’s last “normal” fork, according to Buterin. By “normal,” he means an upgrade built around technologies that would still look familiar to someone working on Ethereum in 2015.
After Hegota, the roadmap becomes increasingly focused on advanced cryptography and verification.
Buterin highlighted recursive STARKs, automated formal verification, more optimised consensus mechanisms and quantum-safe cryptography as key parts of Ethereum’s longer-term development.
Recursive STARKs can allow one cryptographic proof to verify other proofs, while formal verification uses mathematical methods to check whether software behaves according to its intended rules. Quantum-safe cryptography, meanwhile, is designed to protect systems against potential attacks from future quantum computers.
The Hegota upgrade is expected to follow Glamsterdam, which is currently targeted for the fourth quarter of 2026. However, Hegota remains in development, and its full scope is not yet finalised.
What Ethereum could look like by 2030
Buterin’s vision extends beyond upgrades to how users experience Ethereum.
He projects that Ethereum could eventually have block slots of around four to eight seconds and finality of roughly eight to 32 seconds by 2030. Finality refers to the point at which transactions are considered irreversible by the network.
This would represent a significant reduction in the time users wait for transactions to become final compared with earlier versions of Ethereum.
More importantly, Buterin expects Ethereum to become capable of handling computation in a way that is cheaper and more scalable without sacrificing its decentralised security model.
Rather than treating the blockchain as the place where every piece of computation must happen, Ethereum could increasingly use cryptographic proofs and decentralised off-chain systems to perform heavy work while leaving the network to verify the results.
Buterin acknowledged that significant technical challenges remain. Making zero-knowledge proofs cheap and reliable enough for widespread use is one challenge, while managing large amounts of shared blockchain state and coordinating parallel computation could be even more complex.
Still, he sees these technologies as the foundation for Ethereum’s next phase.
“Starting after Hegota, this transformation becomes Ethereum’s primary story,” Buterin wrote.
The long-term goal, he said, is a network capable of providing much cheaper, more scalable and more private high-security computation than was possible with the technology of Ethereum’s earlier era.
That is the idea behind his “cryptographic world computer” , an Ethereum that retains the security principles of a blockchain while using modern cryptography to do far more with the network.
