Buterin: Ethereum is “not just a blockchain anymore” — here's what it will look like by 2030
On September 27, Ethereum co-founder Vitalik Buterin published a post titled “The cryptographic world computer.” His thesis: by 2030, Ethereum will be a blockchain mostly in name. Nodes will stop re-executing every block, transactions will become final within seconds, and signatures will be quantum-resistant. Here's what changes, when, and what it means for anyone holding ETH.
What is Buterin's “cryptographic world computer”?
Out of habit, people call Ethereum a blockchain, just like bitcoin. But according to Buterin, once the upgrades the Ethereum Foundation has laid out in its roadmap through 2029 are in place, almost every property that defines a blockchain will be different. The name will stick around mostly for historical reasons.
Three fundamentals are changing:
- Block verification. Today every node downloads the block and re-executes all of its transactions. In the future, a node will download only a small sample of the data (PeerDAS technology) and check a single cryptographic proof — a SNARK — that the block was computed correctly.
- Consensus. The journey from mining (proof of work) to staking (proof of stake) continues: the next step is a heavily optimized proof of stake with finality within a few slots.
- Block building. Instead of a single producer deciding what goes into a block, there will be several participants. A separate mechanism, FOCIL, will keep transactions from getting “lost” just because someone wants them to.
Buterin describes the result as a hybrid: Satoshi Nakamoto's ideas plus roughly half a century of academic cryptography that either didn't exist in 2009 or was still immature. In a system like this, decentralization is no longer just the price you pay for security. Data storage and computation can be spread across participants, and for some tasks that actually makes the network faster.
Hegotá: the last “ordinary” Ethereum fork
Buterin says the Hegotá fork, planned for next year, will most likely be the last “normal” upgrade. After that, Ethereum's main storyline will be recursive STARK proofs, automated formal verification of code, optimized consensus and protection against quantum computers.
Here's what we know about the upcoming upgrades:
| Upgrade | When | What it brings |
|---|---|---|
| Fusaka | December 3, 2025 | PeerDAS: a node stores only part of the blob data |
| Glamsterdam | Q4 2026, Sepolia testnet on October 6 | builder and proposer roles separated in the protocol itself (ePBS), block-level access lists for parallel execution |
| Hegotá | target: Q2 2027 | FOCIL for guaranteed transaction inclusion; native account abstraction with support for quantum-resistant signatures |
| Later forks | by the end of 2029 | the Ethereum Foundation's goal: quantum resistance at every layer of the network |
The timelines are targets, not promises: the Glamsterdam and Hegotá dates haven't been locked in yet. According to the Ethereum Foundation, ETH holders don't need to prepare for Glamsterdam: balances stay the same. Buying ether doesn't have to wait for the upgrades either: you can simply exchange crypto online for ETH.
Ethereum in 2030: what changes
| Today | By 2030 | |
|---|---|---|
| Slot (block) | 12 seconds | 4–8 seconds |
| Finality | about 13 minutes | 8–32 seconds |
| Block verification | a node re-executes every transaction | a node checks a SNARK proof and a data sample |
| Transaction signature | ECDSA — vulnerable to future quantum computers | quantum-resistant signature or ZK proof |
| Censorship resistance | depends on block builders | guaranteed transaction inclusion (FOCIL) |
| Privacy | transfers are visible to everyone | private transfers via ZK proofs, anonymous transaction broadcasting |
The 2030 figures come from Buterin's post and the Ethereum Foundation roadmap. The nearest step toward them is Glamsterdam, and we covered what the Glamsterdam upgrade changes on Ethereum separately.
What it means for ETH holders
- Speed. Finality in 8–32 seconds instead of roughly 13 minutes today: a transfer becomes irreversible almost instantly.
- Security for years to come. Quantum computers are the biggest long-term risk to crypto signatures. The Ethereum Foundation aims to make the network resistant to them by the end of 2029.
- Privacy. For many applications, Buterin says, privacy on Ethereum will be stronger than on ordinary servers. General-purpose private computation will remain the weak spot.
- Fees. The post gives no numbers. General-purpose computation will stay expensive, while many specialized tasks will get noticeably cheaper: the price will depend on how well an app can run in parallel.
- Your own node. It still gives the strongest guarantees, but the requirements keep dropping. The day before the post, Buterin wrote that an Ethereum node already syncs in under half a day and, with aggressive settings, takes up less than half a terabyte.
Buterin himself names the biggest unsolved problem: handling the network's huge and growing state, which still has to be parallelized.
ETH price: ether heads for a record quarter
While researchers sketch out 2030, the market is marching to its own beat. ETH is trading around $2,700 and has gained about 71% since July 1, up from $1,570. If the quarter closes like this on September 30, it will be ether's best Q3 ever: the previous record was about 67% in 2025.
- Spot ether ETFs pulled in $690 million in net inflows during the week of September 21–25.
- Bitcoin gained 44% over the same quarter, its best Q3 since 2017.
- What the stats say about October: see our breakdown of the Q3 results and “Uptober”.
How to buy ETH without an exchange
Ethereum is the second-largest cryptocurrency by market cap, and you don't need an exchange account to buy it. On VertEXchange you can exchange USDT to ETH without signing up and get the coins straight to your wallet. If you hold bitcoin, you can swap BTC to ETH the same way.
Swap USDT or BTC for ETH without signing up: the coins arrive at your own address, not on an exchange balance.
