LayerZero

LayerZero Research announced Aerie, a system that aggregates post-quantum signatures at high speed. In tests on a MacBook Pro M4 Max without GPU acceleration, it aggregated 32,768 Falcon-512 signatures in 0.65 seconds, and ML-DSA, NIST's standardized default, also runs inside Aerie at high performance.

Aerie is built on Akita, LayerZero's recently announced lattice-based polynomial commitment scheme. The team positioned it as a way for blockchains — which today rely on BLS-style signature aggregation in systems like Ethereum — to prepare for a post-quantum future without sacrificing performance. The announcement and full paper were shared on X.

LayerZero Research published a new paper, Too Late to Slash, arguing that slashing does not reliably back the security of proof-of-stake blockchains.

• The paper challenges the premise that slashing removes the free option validators have to test whether enough peers are willing to attack — by making the act of coordinating an attack itself economically risky.
• The researchers show rational validators can determine whether enough others are willing to attack before producing any slashable evidence: if there aren't enough participants, nothing happens, and if there are, the coalition only equivocates once it is confident an attack will succeed.

The full paper was shared alongside the announcement thread on X.

LayerZero reminded users that it is winding down offchain support for chains with minimal activity, meaning its DVN and Executor services will no longer be available on those networks. Within the next 30 days, Aurora, Taiko and Japan Open Chain will be impacted.

The reminder is part of a broader, phased winddown of offchain support for low-activity chains that LayerZero announced earlier this year, with batches of chains losing services on staggered dates. The tweet did not extend the timeline or add new chains beyond this group.

LayerZero is building an integration with TACEO for cross-chain Merces transfers that keep private balances shielded as they move between networks. The setup conceals both the participants and the size of the transfer while in transit, extending privacy to omnichain transfers. Details on the Merces mechanism and supported networks were not disclosed in the announcement.

LayerZero Research said it has completed formal verification of Jolt's "bytecode expansion" — the process Jolt uses to emulate RISC-V instructions it doesn't handle natively by breaking them down into instructions it does. The work covers a core component of Jolt, the zk-VM powering Zero's proving architecture.

The team is releasing all related artifacts, including a preprint of the paper. LayerZero framed formal verification as stronger than conventional testing, which can only sample a subset of inputs, whereas formal verification proves behavior across all cases.

Anchorage Digital, home to America's first federally chartered crypto bank, has selected LayerZero as its interoperability partner for regulated stablecoin issuance. US-regulated stablecoins issued through the Anchorage platform — including Tether's USAT, Western Union's USDPT, and OSL Group's USDGO — can now be connected to 170+ chains, powered by LayerZero's OFT standard.

LayerZero followed up by framing the selection for banks, corporate treasuries, and payment providers that operate under regulatory oversight, arguing that stablecoin asset infrastructure must meet jurisdiction-specific regulatory requirements. The company pointed to additional material detailing the partnership supporting regulated stablecoin issuance.

Trading platform Sunrise is using LayerZero's OFT standard to bring a broad set of assets onto Solana, including via the $INJ bridge, where they can then be traded on-chain. The integration is powered by LayerZero's Value Transfer API, extending multichain asset transfer to Solana traders. The announcement is brief and does not detail the full list of assets or specific mechanics beyond the OFT-based bridge.

LayerZero Research published two papers detailing structural weaknesses in Poseidon, one of the most widely used hash functions in zero-knowledge proving systems. Poseidon is used in protocols the Ethereum Foundation has been evaluating for post-quantum signature aggregation, and the findings were submitted to the foundation's Poseidon-related review effort.

The research team linked the work to its broader focus on evaluating the cryptographic primitives the industry relies on today, including its lattice-based Akita commitment scheme for post-quantum security.

LayerZero announced its endpoint is live on Arc from day one, giving builders on the network native cross-chain messaging for any asset issued there. Issuers moving assets onto Arc can use LayerZero infrastructure that the company says secures 87% of cross-chain transfer volume, while connecting Arc to LayerZero's network of 170+ chains.

LayerZero recirculated its announcement of Akita, which it calls the first production-ready lattice-based polynomial commitment scheme for post-quantum security, framing it as the first step toward making the Zero blockchain quantum-secure.

• Akita is positioned as a standalone primitive any proof system can adopt, with its landmark integration being Jolt, the zkVM LayerZero is building alongside a16z crypto.
• Both Jolt and Jolt Pro — the implementation underpinning Zero — will use Akita.
• LayerZero notes lattice-based cryptography is what NIST standardized for post-quantum encryption, positioning Akita as bringing that standard to blockchain proof systems.

No timeline was given for Zero's full quantum-readiness; the recap reiterates the original announcement and accompanying paper rather than adding new details.
