According to Odaily, Bitcoin's ZK Rollup protocol, Citrea, has officially opened its public beta network, inviting developers and users to participate in its testnet construction. Previously, Citrea had successfully raised $2.7 million in seed funding, with Galaxy Ventures leading the investment round.

The launch of the public beta network marks a significant step in Citrea's development, providing an opportunity for developers and users to engage with the protocol and contribute to its refinement before the full launch. The seed funding round, led by Galaxy Ventures, has provided the necessary financial support for this phase of development.

The ZK Rollup protocol is a layer 2 scaling solution for Bitcoin, designed to increase transaction speed and reduce costs. By launching its public beta network, Citrea is taking a significant step towards improving the scalability of Bitcoin, which has been a long-standing issue in the cryptocurrency community. The successful seed funding round indicates strong investor confidence in the potential of the ZK Rollup protocol and Citrea's ability to deliver on its promises.
