April 11: QED Protocol , the world’s first zk-native blockchain protocol, together with StarkWare, zkLink, Mina Protocol, O(1) Labs, announced the launch of the L2O Consortium , a group of projects and protocols committed to bringing Bitcoin’s native security, internet scale, and interoperability to applications and Layer 2 solutions. According to a press release: “The consortium is developing reference implementations, tools, and resources for developers looking to build DApps or deploy Layer 2s on top of Bitcoin and enable trustless interoperability between applications by coordinating standards across solutions, leveraging ordinals and zero-knowledge proofs to bridge the technical gaps that previously hampered smart contract-like functionality on Bitcoin.” The reference implementations are here in the project documentation .
