After zkSync Era was launched for developers-only last month, the project took the additional step Friday of opening to general users. The latest push by Matter Labs comes just days ahead of the rival Polygon system’s planned rollout Monday of its own “zero knowledge Ethereum Virtual Machine.”

Zero Knowledge proofs offer robust security and scaling for the latest crypto products. OpenZeppelin’s Stephen Webber writes about how developers could build more secure ZK proofs.

The backing Aztec Network is open sourcing the bridge and moving on to next-generation products.

Framework Ventures led the seed round for the firm, which was founded by former employees of market maker Jane Street.

Privacy Pools uses zero-knowledge proofs to prove that funds in anonymous transactions are not linked to criminal activity, such as North Korea’s $625 million hack on Axie Infinity.

Zero-knowledge or ZK, a type of cryptography, is seen as one of the year‘s hottest blockchain technologies. ConsenSys launched a private zkEVM testnet in December, but is now opening it up for anyone to join.

Under the design for Polygon ID, a bar owner could theoretically use the credential-verification system to verify that a patron is of age, without ever having to look at any identification card.

Matter Labs has renamed zkSync 2.0, its zero-knowledge rollup platform, to “zkSync Era” and is making its code open-source.

Details about the zkEVM beta network will be released over the next few weeks. The launch is set for March 27.

In an exclusive interview with CoinDesk, Polygon’s co-founder Mihailo Bjelic shared the progress the blockchain is making on becoming a ZK-secure ecosystem.

The firm has already raised $22 million to build a suite of zero-knowledge developer tools.

The fundraise was led by Haun Ventures and included Maven 11, 1KX, Robot Ventures and Plaintext Capital.

The funding round led by Polychain Capital aims to make zero knowledge projects more decentralized, and easier to build.

The updated version of Nightfall, which uses zero-knowledge proofs to ensure data privacy, will go live at an EY innovation event in May this year.
