Breaking down Bitcoin bridges: Insights from RootstockLabs
Bitcoin faces challenges in bridging due to strict consensus rules and a limited scripting language, complicating crosschain transactions. Bitcoin Virtual Machine (BitVM) protocols have been developed to enhance interoperability but introduce trade-offs like increased complexity and reduced decentralization. The scripting language lacks the expressiveness needed for decentralized bridges, limiting past efforts. BitVM protocols often rely on trusted parties for dispute resolution, which compromises security and decentralization. BitVMX, an improved version, offers a more efficient method for Bitcoin bridging, enabling participation in broader blockchain applications. However, rigorous testing is essential to mitigate risks associated with deploying BitVM-based systems.
