Citrea, Bitcoin's ZK Rollup protocol, has launched its Public Devnet, marking a significant milestone in the development of the protocol. The launch targets developers and users, providing a platform for testing and experimentation. The Public Devnet signifies the testing of Bitcoin as a data availability layer, establishing it as the foundation of a dynamic financial ecosystem.

The team is currently engraving the state differences and batch zero-knowledge proofs into Bitcoin, testing sequencers, provers, and full node software. This development is crucial in establishing the protocol's functionality and ensuring its compatibility with the Bitcoin network. However, the Public Devnet has not yet implemented Clementine or BitVM in terms of cross-chain, instead using proof sampling to prove each sequencer commitment.

The launch of the Public Devnet is a significant step forward for Citrea, as it enables developers and users to test and experiment with the protocol. The protocol's ability to establish Bitcoin as a data availability layer has the potential to revolutionize the financial ecosystem, providing a new level of security and efficiency.

The team behind Citrea has made significant progress in recent months, completing a seed round of financing of $2.7 million. The round was led by Galaxy Ventures, with participation from Delphi Ventures, Taproot Wizards co-founder Eric Wall, and modular blockchain Avail co-founder Anurag Arjun. This funding will enable the team to continue developing the protocol and expanding its capabilities.

In conclusion, the launch of Citrea's Public Devnet is a significant milestone in the development of the protocol. The launch provides a platform for testing and experimentation, enabling developers and users to test the protocol's functionality and compatibility with the Bitcoin network. The protocol's ability to establish Bitcoin as a data availability layer has the potential to revolutionize the financial ecosystem, providing a new level of security and efficiency.
