computer."

planned for late 2026 or 2027, is expected to be Ethereum's last
"normal" fork.

cryptography, and a redesigned consensus.
- Block
times could drop from 12 seconds to 4-8 seconds, with finality dropping
from minutes to seconds.
Ethereum co-founder Vitalik Buterin says Ethereum is no
longer "just a blockchain." In a new essay published on September 27,
he described the network as a "cryptographic world computer" — a
hybrid system that combines blockchain consensus with modern cryptography,
zero-knowledge proofs, and decentralized computation .
The essay, titled "The Cryptographic World
Computer," outlines how Ethereum will change after the Hegota upgrade,
which is expected in late 2026 or 2027.
Buterin wrote on X that Ethereum is "really not just a
blockchain anymore" — it's "a hybrid architecture that combines
blockchains and modern cryptography, to enable much more powerful
properties" .
What Hegota Changes
Buterin described Hegota as Ethereum's last
"normal" fork — meaning it will still include features that would
look familiar to someone working on the network in 2015. After Hegota,
everything changes.
The headline feature of Hegota is FOCIL (Fork-Choice
Enforced Inclusion Lists). This is a censorship-resistance mechanism that
forces validators to include valid transactions in blocks. Under FOCIL, a
committee of 17 randomly selected validators creates a list of transactions
that must be included. If a block builder ignores that list, the network
rejects the block .
Why does this matter? In the past, large validators have
excluded transactions tied to sanctioned protocols like Tornado Cash. FOCIL
makes that kind of censorship much harder, because an attacker would need to
control both the builder and the committee — an extremely difficult and costly
task .
Buterin said FOCIL, combined with EIP-8141 (account
abstraction), gives "guaranteed rapid inclusion" for almost any valid
transaction, including smart wallet transactions and privacy protocol
transactions, within one to two slots .
What Comes After Hegota
After Hegota, Ethereum's roadmap shifts toward what Buterin
calls "cryptographic" infrastructure:
- Recursive
STARKs — Instead of every node downloading and re-executing every
block, a single computer would generate a concise cryptographic proof that
it followed the rules. Other nodes would verify that proof, which is
orders of magnitude faster than re-executing the computation .
- PeerDAS
data sampling — Nodes would verify data availability by sampling parts
of the dataset instead of downloading everything .
- Quantum-resistant
cryptography — The Ethereum Foundation has set a December 2029 target
for making Ethereum's execution, consensus, and data layers
quantum-resistant .
- Lean
consensus — A redesigned consensus mechanism aiming for faster
finality and simpler architecture .
Buterin also named concrete performance targets for 2030:
block time falling from about 12 seconds today to 4 to 8 seconds, and
finality from several minutes to 8 to 32 seconds .
Why This Matters
Ethereum's shift from "download and re-execute" to
"verify proofs" is a fundamental change in how blockchains work. It
could reduce hardware requirements for validators while increasing throughput.
Buterin said nodes should still obtain consensus and validity guarantees while
storing less history and performing less redundant computation .
The change also has implications for Layer 2 networks. FOCIL
is designed to strengthen Layer 2 settlement guarantees, making it harder for a
single actor to censor transactions that need to settle on Ethereum .
Buterin acknowledged that making proof systems efficient
enough for widespread use remains difficult. But he said AI tools are helping
progress, and the 2030 vision is a technical direction rather than a locked
schedule .
Frequently Asked Questions
What is FOCIL?
FOCIL stands for Fork-Choice Enforced Inclusion Lists. It's a mechanism that
forces validators to include valid transactions in blocks, making censorship
harder .
When is Hegota happening?
Hegota is planned for late 2026 or 2027, following the Glamsterdam upgrade .
What is a "cryptographic world computer"?
It's Buterin's term for Ethereum's future architecture — a system that combines
blockchain consensus with zero-knowledge proofs, data sampling, and
decentralized computation .
Will Ethereum become quantum-resistant?
The Ethereum Foundation has set a December 2029 target for quantum resistance
across execution, consensus, and data layers .
Bottom line: Buterin says Ethereum is no longer just
a blockchain. After Hegota, it becomes a cryptographic world computer — with
FOCIL forcing transaction inclusion, recursive STARKs replacing re-execution,
and quantum resistance on the horizon. The shift is technical, but it changes
what Ethereum is at its core.
