Starknet v0.14.3 Adds Individual Migration to BLAKE2s-256

By Daniel Okafor

StarkWare released Starknet v0.14.3 with a switch from Pedersen to BLAKE2s-256, according to the release announcement, allowing accounts to migrate individually without a chain-wide signing upgrade.

What changed in v0.14.3?

Starknet, an Ethereum Layer 2 network, now has a release centered on two linked changes: the switch to BLAKE2s-256 and per-account migration. The announcement describes the hash replacement as part of version 0.14.3 rather than as a future roadmap item.

Individual migration is the key operational feature. StarkWare says accounts can move “without requiring a chain-wide signing upgrade,” because the release supports moving them one by one. Users therefore do not have to complete the signing change in one synchronized, network-wide event.

The release announcement does not set a final deadline for completing account migrations, state that every account has moved or identify a mandatory cutover date. It also does not enumerate wallet, client or service requirements. Those details remain outside the announcement, so the verified release scope is the BLAKE2s-256 switch and the option to migrate accounts individually.

That scope separates chain-level coordination from ecosystem readiness. The release does not require a chain-wide signing upgrade, but the announcement does not say whether applications and account interfaces are ready or identify their version-specific dependencies. It also provides no staged deployment calendar.

Starknet remains an Ethereum Layer 2 network under the release described by StarkWare. The software change does not by itself alter that network status, and the announcement presents no token, fee, validator or settlement-market changes alongside the hash update.

Does v0.14.3 complete the post-quantum goal?

No. StarkWare says Starknet’s broader goal is “full post-quantum security in 2027.” The announcement does not say v0.14.3 completes that target or makes the network fully post-quantum secure.

The release establishes a present-tense technical change, while the 2027 statement establishes a future objective. The announcement does not provide a complete milestone schedule for the intervening period, identify this version as the final post-quantum upgrade or define completion criteria.

The defensible reading is that StarkWare has moved Starknet from Pedersen to BLAKE2s-256 while the 2027 target remains outstanding. That distinction limits what users, developers and governance participants can infer from the version number: the release confirms a software and account-migration mechanism, but it does not quantify the remaining work needed for full post-quantum security.

What does the Layer 1 study change?

StarkWare and the Starknet Foundation are separately studying a possible independent Layer 1, according to the announcement. The study is distinct from v0.14.3, and the source describes an exploration rather than a committed launch.

The announcement sets out two next steps:

• StarkWare plans to publish a draft white paper in November.
• The Starknet Foundation plans to post findings to its governance forum as work progresses.

No launch date accompanies the study, and the source does not set out a final design, token, validator set or funding plan. Because the chain is described as possible, the November paper is a disclosure milestone rather than authorization to begin operation.

The Foundation’s planned governance updates also remain open-ended. Posting findings as the work develops does not itself establish a vote, a vote date or a binding decision. The announcement does not say whether the Foundation will put a specific proposal to community members or what options governance participants will consider.

The Layer 1 work therefore sits outside the immediate v0.14.3 migration. One track updates Starknet as an Ethereum Layer 2; the other studies a possible independent chain and directs the findings toward further governance review.

The next disclosed checkpoint is StarkWare’s planned November draft white paper, with the Starknet Foundation set to post findings to governance as work progresses; no Layer 1 implementation date appears in the announcement, and full post-quantum security remains a stated goal for 2027.
