Ethereum in 2030, explained for everyone

Introduction

Ethereum launched in 2015 and is now in its eleventh year. In that time it swapped its consensus mechanism from proof of work to proof of stake through the Merge, and it has kept changing since, through Shapella, Dencun, Pectra, and Fusaka. Ethereum is a chain where something is always in motion. Which means that before you invest in it, or build something on it, it helps to know what shape it is trying to change into.

In July 2025, one day after Ethereum turned ten, Ethereum Foundation researcher Justin Drake published the lean Ethereum vision. Lean means stripped of excess weight. It is a roadmap that takes Ethereum's scattered research threads and directions, keeps only what is necessary, and presents that as a single vision. Think of a ten-year-old house where the exterior stays as it is, but the foundation, the plumbing, and the wiring get replaced.

That vision became concrete in February 2026 as a document called the Strawmap. As the name suggests, it is a strawman: not a fixed plan but a living document that keeps getting revised as the community discusses it. It was updated again on June 26. The latest version lays out the hard forks running from Glamsterdam, scheduled for the second half of 2026, through 2029, along with the five destinations all of those upgrades ultimately point toward. It calls them north stars.

This piece follows those five north stars to sketch what Ethereum will look like in 2030, about four years from now.

Fast L1: an even faster mainnet

The first north star is the speed of Ethereum L1 itself. On today's Ethereum, a transaction takes roughly 15 minutes to reach finality, the state where it can no longer be reverted. Around 880,000 validators cannot all vote on every block, because collecting and processing that many signatures at once is more than the network can handle. So Ethereum splits validators into 32 groups that vote in turn, and finalization requires two full passes through that cycle.

Lean consensus removes this bottleneck with ZK proofs. Once hundreds of thousands of votes can be compressed into a single small proof, every validator can vote on every block and have those votes aggregated on the spot. The target is single-round finality.

Block time gets shorter too. Ethereum currently produces a block every 12 seconds. Those 12 seconds are 4 seconds each for three steps: the proposer propagating the block worldwide, validators voting on it, and those votes being collected.

That budget was set conservatively in 2020, when the Beacon Chain, the consensus layer of proof-of-stake Ethereum, was designed around home computers and slow connections. Client software and global network conditions have improved since, and measurements confirm each step now finishes well inside its allowance. On that basis, cutting block time from 12 seconds to 6 is planned for around 2027 to 2028. Lean consensus, planned for 2029 to 2030, then introduces a next-generation P2P protocol that spreads blocks and votes far faster, taking block time to 4 seconds.

At a 4-second block time, the wait between sending a transaction and seeing it execute falls to roughly 2 seconds on average. Add the shorter finality on top, and sending a transaction, executing it, and confirming it irreversibly all fit inside a few seconds.

Lowering the minimum stake required to run a validator from 32 ETH to 1 ETH is another lean consensus goal. A lower bar means more people can take part in the network directly. Ethereum in 2030 aims to be faster and, at the same time, more decentralized, with more people participating in consensus themselves.

Gigagas L1: a billion gas per second

The second north star is throughput. Gas is the unit Ethereum uses to measure computation. Ethereum L1 currently handles about 5 million gas per second, and the goal is 1 billion gas per second, a gigagas. That is roughly a 200x increase in mainnet throughput.

The biggest obstacle sits in re-execution, the basic verification model of a blockchain. When a new block is produced today, thousands of nodes around the world each re-run every transaction inside it from scratch. One student solves the problem, and then the entire class solves the same problem from the beginning to check the answer. This was the surest way to make a decentralized network trustworthy, and it is also the main reason decentralization and scalability have been hard to hold at once. To let anyone run a node, throughput has to stay low. To raise throughput, you have to depend on a small number of high-performance nodes.

The technology that breaks this deadlock is, again, ZK proofs. If the node that built a block also submits mathematical evidence that every transaction inside it executed correctly, the remaining nodes only need to check that evidence instead of re-running the transactions. Verifying a proof is light enough to do on a mobile device. Applying this to L1 block verification is L1 zkEVM, and the Ethereum Foundation published an official roadmap for it in February 2026.

According to the Strawmap, the first stage runs re-execution and ZK proofs side by side, an optional proving phase. Around 2028 to 2029 it moves to mandatory proving, where a block is verified by its proof alone. From that point, no matter how many transactions a block holds, the verification burden stops growing. That is what justifies raising the gas limit continuously, with 1 billion gas per second as the end goal.

For users, it also means verifying the entire chain directly from wherever the wallet already lives, a phone or a web browser, without trusting an external RPC. In verification, Ethereum moves past decentralization to being trustless.

Teragas L2: a data highway for countless rollups

The third north star is for L2s. An L2, or rollup, executes transactions outside Ethereum proper and writes only the resulting data to L1, inheriting its security. The dedicated space for storing that data on L1 is the blob, and total blob capacity is the ceiling on the throughput that all L2s combined can produce.

The Fusaka hard fork in December 2025 introduced PeerDAS, which lets each node verify only a portion of blob data. That laid the groundwork for a large increase in blob count, and Glamsterdam has candidates that make blob networking and storage more efficient. The Strawmap targets steady annual increases in this data capacity, ending at 1 gigabyte per second, the teragas class. Enough for a feature film's worth of high-definition data to move across Ethereum every few seconds.

The roadmap makes Ethereum's division of labor clear. Even with every item complete, there is a structural limit to how far L1 throughput can go against a high-throughput chain like Solana. Applications that demand that level of performance will onboard to Ethereum through their own L2 instead.

Robinhood already launched Robinhood Chain, its own Ethereum L2 for tokenized equities. It inherits Ethereum's security as is, and handles its own requirements, regulatory compliance among them, on its own chain.

So Ethereum in 2030 will be a large settlement network where an L1 responsible for final settlement and security coexists with L2s each optimized for its own purpose.

Post-quantum L1: Ethereum that survives quantum computing

The fourth north star is quantum resistance. Ethereum's current signature schemes, ECDSA for wallets and BLS for validators, break in front of a sufficiently large quantum computer. The US National Institute of Standards and Technology (NIST) has signaled that ECDSA should be deprecated from 2030 and disallowed from 2035, and Google has set 2029 as its own deadline for moving its systems to quantum-resistant cryptography. The arrival of quantum technology capable of breaking Ethereum's cryptography is approaching faster than expected.

The main goal here is replacing the signature schemes with hash-based cryptography, which holds up against quantum attacks. Hash-based signatures also pair well with ZK proofs, which ties this work back to gigagas L1. The Ethereum Foundation formed a dedicated post-quantum (PQ) team in January 2026 and put up $1 million in prizes for verifying hash function security.

In the Strawmap, the transition spans several forks. It starts with pre-registering quantum-resistant public keys, then moves through validator attestations and signatures and on to the transaction and data layers, arriving at a hash-based L1 around 2029. If that goes to plan, Ethereum will still be safe once quantum computing arrives.

Private L1: privacy as a default

The last north star is something Ethereum has never had. Every transaction on Ethereum today is visible to the entire world. Anyone with an address can see that account's balance and every transfer it has ever made. For individuals that is a privacy problem. For companies that want to run payroll or supplier payments onchain, it blocks adoption outright.

Shielded transfers, the goal of private L1, put today's postcard-readable transactions into an envelope. Sender, receiver, and amount are hidden, while a ZK proof shows the network that the transaction followed the rules. ZK proofs run through every part of Ethereum's roadmap, and nothing else in it carries as much weight.

According to the Strawmap, the groundwork for privacy could land as early as the Hegotá hard fork, with mempool changes that encrypt transaction contents while they wait to be included following in the next upgrade. Privacy is the least specific of the north stars, though. It is also sensitive to the regulatory environment, which makes it the most uncertain of the five. Even so, Ethereum has for the first time made L1-level privacy an official roadmap goal, and that alone is a large shift.

Closing

One line for each of the five north stars:

• Fast L1: finality falls from 15 minutes to seconds, and block time from 12 seconds to 4.
• Gigagas L1: ZK proofs replace re-execution, and L1 processes 1 billion gas per second, roughly 200x what it does today.
• Teragas L2: data capacity for L2s grows to 1 gigabyte per second, enough for many L2s to run on top of it.
• Post-quantum L1: signature schemes move to hash-based cryptography, holding up in the quantum computing era.
• Private L1: hiding the contents of a transaction while proving its validity becomes a standard Ethereum feature.

Who drives this roadmap is changing as well. The Ethereum Foundation recently cut around 20% of its headcount and is gradually narrowing its role, and new organizations are filling the space. In June 2026, Ethlabs launched, a nonprofit R&D organization backed by Ethereum DAT companies and Ethereum co-founder Joseph Lubin. A week later came Ethereum Institutional, founded by people who had run the Foundation's enterprise team. Ethereum is heading toward something closer to fully open source, built by a small foundation alongside many separate actors.

None of this is guaranteed to land as planned. The Strawmap is a draft under constant revision rather than a settled roadmap, and Glamsterdam, the very next hard fork, has already slipped from the first half of 2026 to the second. Schedules can slip, the cryptography needs more time under review, and what goes into which fork will keep shifting as researchers and the community argue it out.

Whatever shape it ends up taking, Ethereum will hold its place as the most neutral and trustless computing network in the world. The Strawmap is a specific commitment to becoming faster, larger, and safer without giving up that identity.
