Starknet said on 8 October 2026 that it is actively considering becoming an independent layer-one blockchain, with a stated goal of reaching full quantum resistance in 2027. StarkWare co-founder and chief executive Eli Ben-Sasson framed the option as a way to control the network’s cryptographic upgrade schedule rather than depend on Ethereum’s timeline.

The distinction between an idea and an approved network transition is crucial. No Starknet Improvement Proposal, governance vote, final validator design, migration plan or launch date accompanied the statement. The current public Starknet roadmap still describes the network as an execution layer settling to Ethereum and, eventually, Bitcoin. That roadmap was last updated on 22 March 2026 and has not yet been replaced by a formal L1 plan.

Why the Ethereum dependency matters

Starknet currently operates as an Ethereum layer two. It executes transactions away from Ethereum, produces validity proofs and uses Ethereum for settlement and data availability. That relationship gives Starknet access to Ethereum’s economic security and exit guarantees, but it also means some system-wide protections cannot become fully quantum-safe until the underlying Ethereum components change.

Starknet’s own August technical explanation divides the problem into two layers. Its STARK proof system relies on hash functions rather than the elliptic-curve cryptography used by many proof systems, giving the verification layer a stronger starting point against known quantum attacks. Smart-contract accounts can also adopt alternative signature checks without requiring every user to change address at the same time.

However, Starknet’s bridge to Ethereum and the data-availability path still inherit cryptographic dependencies from the base layer. An independent chain could replace those dependencies on its own schedule. It would also give up the simple claim that Ethereum ultimately settles the network’s state, forcing Starknet to define and fund its own base-layer consensus, validator incentives, security budget and recovery process.

The proposal would change more than cryptography

Moving from an L2 to an L1 is not a narrow software upgrade. It changes who orders and finalizes transactions, what backs the bridge, how users exit during an outage, and where economic security comes from. Existing applications, liquidity and custodial integrations would need clear migration guarantees.

The role of STRK would probably become more central if an independent network used it for validator staking and base-layer security. But that is an inference, not a disclosed token model. No new issuance schedule, staking requirement, fee allocation or security budget has been published for an L1 version of Starknet.

There is also a trade-off between speed and inherited security. Independence may let developers deploy post-quantum changes faster, yet it transfers more responsibility to Starknet’s own governance and validator set. A rapid migration with weak testing or concentrated validation could replace one dependency with another.

What is already real

Starknet’s post-quantum work predates the L1 discussion. The network reported an experimental mainnet transfer using a Falcon-512 post-quantum signature account, while emphasizing that the implementation was unaudited and intended for research. Its published roadmap describes phased replacement of remaining elliptic-curve-dependent components and tooling for existing contracts.

Starknet’s separate decentralization roadmap also lists quantum-resistant cryptography, decentralized block validation and later fully decentralized network operation. Those are real engineering directions, but they do not prove that a standalone L1 can be delivered by 2027 or that users, applications and liquidity can migrate without disruption.

NetNapz assessment

Base case: the announcement opens a strategic design process rather than confirming an Ethereum exit. Starknet is likely to compare an independent chain with a faster post-quantum path that retains Ethereum settlement, while developing the missing governance and migration details.

Bull case: Starknet publishes a technically credible architecture, demonstrates audited post-quantum accounts and verification, attracts a diverse validator set, and gives applications a low-risk migration path. A clear STRK security role and transparent economics could strengthen the token’s utility rather than merely its narrative.

Bear case: the L1 idea fragments liquidity, weakens Ethereum-backed exit guarantees or requires a security budget that the network cannot sustain. Delays, governance opposition or a poorly specified bridge could leave the 2027 target as an aspiration rather than an executable programme.

Confirmation and invalidation: confirmation requires a formal proposal, code, audits, validator and data-availability specifications, token economics, governance approval and a staged testnet. The thesis weakens if no proposal appears, the official roadmap continues to prioritize L2 settlement, or technical review shows that independence does not materially accelerate full quantum protection. The relevant horizon is 2027, not the immediate market response.

What to watch next

• A formal Starknet Improvement Proposal or governance discussion defining the L1 architecture.
• The validator, consensus, staking and security-budget model for STRK.
• Audits of post-quantum account and verification components.
• Plans for bridges, application state, liquidity and user exits during migration.
• Whether Starknet formally replaces its existing Ethereum-and-Bitcoin settlement roadmap.

The verified development is that Starknet’s leadership is considering independence and has attached a 2027 quantum-security ambition to the idea. Calling the move approved—or assuming it automatically creates sustainable STRK demand—would go beyond the available evidence.
