Switzerland-based blockchain startup Aleph Zero has launched a testnet for its ZK-privacy layer-2 solution, zkOS, which is capable of achieving subsecond proving times.

Aleph Zero, a Swiss firm focused on developing privacy-first blockchain solutions, is introducing the developer testnet for its Aleph Zero EVM layer-2 solution, zkOS. This solution is notable for its ability to achieve subsecond proving times, a significant improvement over the minutes required by other solutions.

Built in partnership with Gelato, a Rollup-as-a-Service provider, zkOS leverages Arbitrum Anytrust DAC. This is a permissioned set of parties responsible for enforcing data availability within an Arbitrum AnyTrust Protocol chain.

“Privacy will become a major narrative in 2024 and beyond, as more mainstream use cases emerge,” said Gelato founder Luis Schliesske.

The network claims it can generate a block in under 250ms with near-instant transaction finality, thereby processing thousands of transactions per second. The developer mainnet is expected to be released in Q3 2024, with further advanced features anticipated by Q1 2025.

According to the Zug-headquartered firm, initial benchmarks show zkOS zero-knowledge proofs can be executed in 600-800 ms on MacBooks (M1-M3 processors) using browsers like Safari or Chrome.

Founded in early 2018, Aleph Zero aims to empower the creation of high-speed and confidential decentralized applications. The company has successfully raised over $14 million through pre-seed and seed funding rounds, alongside community and public sales of its AZERO tokens.
