The Rollup Bitcoin and Beyond EP9: Rollux's Merged Mining, Data Availability, and Bridging
We've been diving heads first into the technical design structure of Bitcoin L2s over the last two weeks with the goal of uncovering what is really happening behind the scenes in this space.
Today's video, we did just that with Jagdeep Sindhu. Jag is a seasoned Bitcoin OG and has a strong opinion about the acceptable trust assumptions in Bitcoin scaling designs.
Jag's vision is to transform Bitcoin into a 'super chain' where utility and security are both achievable without unnecessary tradeoffs. Rollux uses merge mining to borrow Bitcoin's security, while introducing chain locks every fifth block to enforce finality and prevent long-range attacks on the sidechain.
They also have their own zk based DA solution which powers their chain. By combining elements of PoW and PoS for enhanced security, Rollux is trying to build secure interoperability solution. We discussed the future outlook for Rollux being a secure transfer hub for Bitcoin and other chains like Ethereum and Avalanche as well.
We enjoyed the depth of the technical architecture on this conversation and Jag answered all of our questions regarding Bitcoin security and more.
