A collaborative effort among top Bitcoin developers from multiple teams has yielded a potential breakthrough in the Bitcoin blockchain, outlining a method to incorporate 'covenants,' a type of programming that could unlock essential features such as advanced wallet and vault functionalities, as well as more efficient layer-2 protocols, all without altering the main underlying code, thereby avoiding the complexities associated with a soft fork. The proposed technique, detailed in a research paper titled 'ColliderScript: Covenants in Bitcoin via 160-bit hash collisions,' has garnered attention as the Bitcoin network strives to enhance its programmability and support additional layers, with the ultimate goal of rivalling the capabilities of the Ethereum blockchain while maintaining Bitcoin's robust security.
Led by Ethan Heilman, the team behind this innovation includes Victor Kobolov and Avihu Levy from StarkWare, as well as Andrew Poelstra, a veteran Bitcoin developer and current head of research at Blockstream. While the concept has been praised as ingenious, with one developer noting it as a 'pretty awesome idea,' its current form is deemed impractical due to the high execution costs, estimated to exceed $10 million.
Despite this, there is optimism that future optimizations could make the idea more feasible.
