Starknet is actively considering leaving Ethereum to become a standalone layer-1 blockchain, with a target of full quantum resistance by 2027. The plan has not been approved, but StarkWare CEO Eli Ben-Sasson has said the network wants to run its own post-quantum security migration instead of waiting for Ethereum, which currently targets full quantum resistance by the end of 2029.
STRK jumped about 33% in 24 hours after the news broke, according to CoinDesk markets data, before settling back. The token price move aside, the substance is unusual. Layer-2 networks compete on staying attached to Ethereum’s security, and their token pitches lean on inheritance. A public plan to detach is close to a first, and STRK holders, whose asset has been marketed as an Ethereum-adjacent bet, are reading it as a repositioning of the network’s entire pitch.
Why Starknet thinks it has the option
Starknet’s case rests on its cryptography. The chain is built on STARK proofs, which verify computation with hash functions rather than the elliptic-curve signatures that secure bitcoin and most of crypto. Grover’s algorithm, the best known quantum attack against hash functions, only speeds up brute-force search, and doubling the hash length cancels it out. The verification layer that secures every Starknet transaction was never quantum-vulnerable in the first place, which is a property of how STARKs work rather than a recent patch.
Accounts add the second piece. On Starknet, each account contract sets its own rules for which signatures it accepts. In August, Starknet researchers executed a mainnet transfer with an experimental, unaudited wallet that had swapped its elliptic-curve signature for a quantum-resistant one. The transfer cost about six cents and settled publicly on mainnet, with no fork, no coordinated migration and no new address. A hypothetical bitcoin or Ethereum post-quantum rollout, by contrast, is a multi-year coordination problem across millions of keys, many of them held by parties who no longer control their coins at all.
That contrast is the heart of the StarkWare argument. Ben-Sasson argues quantum threats may arrive sooner than expected, and that chains need a way to enter what he calls refuge mode rather than be caught mid-migration. Since Ethereum targets quantum resistance by end-2029 and Bitcoin has made no commitment at all, a Starknet L2 currently inherits a security ceiling set by a base layer that is, on his argument, the weaker link in the stack.
What detaching actually means
Nothing is settled. Settlement, bridging and governance are the open questions, as The Defiant’s coverage notes, and each one cuts against the reason projects chose Starknet as an L2. Settlement is the promise that disputes resolve using Ethereum’s own data, and it is what exchanges and custodians rely on when they list an L2 token. Bridging is how assets arrive and exit, and most Starknet TVL landed through Ethereum bridges with security assumptions tied to the L1. Governance is also unsolved: an independent chain needs a governance design of its own, and building one is a protocol redesign, not a parameter change.
Quantum threats may arrive sooner than expected, requiring blockchain networks to enter a refuge mode and become quantum-resistant.
Ben-Sasson’s framing, reported by Gate News on Oct. 9, is that a Layer 1 transition would let Starknet independently manage its security migration and operate as a quantum-resistant network for public use.
The timing is not random. Days earlier, Abstract, the Pudgy Penguins consumer chain, became the second Ethereum layer-2 to shut down within a week, per CoinDesk, and observers across the ecosystem have begun openly questioning whether the L2 model concentrates too much value in sequencers and token economics while inheriting a base layer whose blob fees keep climbing as more rollups launch. Starknet’s move reads as a bet that protocol independence, not cheap inheritance, is what the next phase of the market will pay for.
The market read
Traders treated it as a governance event first and a cryptography story second. A 33% move on a not-yet-approved roadmap shows how thinly token holders discount the gap between plan and execution, and the drop back off the high suggests positions closed once the market read the caveats. Starknet’s own blog post from August stays careful on the same point: an account can upgrade itself, but migrating the entire network’s state, apps and infrastructure is a different order of problem.
Ethereum researchers have pushed back on the urgency narrative in a related episode this week. After Ethereum Foundation researcher Justin Drake called for a bunker mode over quantum risk, a call that added to negative sentiment during Thursday’s selloff, Coinbase cryptographer Yehuda Lindell dismissed the concerns as FUD in comments carried by CoinDesk, saying there is no evidence the elliptic-curve assumptions behind bitcoin and ether have been broken.
So the industry now holds two live positions. Ethereum’s establishment trusts the standard cryptography for years to come, while StarkWare, the firm that built much of Ethereum’s zk-rollup tooling, is preparing for a 2027 migration and is willing to detach from Ethereum to control the timeline. Which side turns out right matters less, near term, than the precedent: for the first time a major L2 is stating publicly that anchoring to Ethereum is a design choice rather than an identity.
If the proposal advances, Starknet would join a short list of rollup-native chains that graduated to independence, and Ethereum would face its first high-profile L2 departure of the current cycle. The ripple effect would reach other L2s negotiating their own fee structures and app-chains that chose Starknet for its Ethereum anchor. Watch three things: an actual on-chain governance proposal, a settlement and data-availability redesign, and what the Starknet Foundation says about STRK token economics on a chain that would no longer pay Ethereum for large shares of its costs.
