Bitcoin Developer Proposes BitVM: Compute Anything on Bitcoin
A Bitcoin developer named Robin Linus has released a paper called “BitVM: Compute Anything on Bitcoin,” which introduces a way to enable more complex smart contracts on the Bitcoin network. This development could potentially allow developers to build more advanced applications on Bitcoin, similar to those seen on Ethereum. While some are skeptical of BitVM, if it proves successful, it could have significant implications for what can be built on top of Bitcoin.
BitVM’s Potential Applications
In his paper, Linus suggests that BitVM could be used for sidechains and rollups. Sidechains are parallel networks that run alongside blockchains, while rollups bundle transactions before reporting them on the main network. These technologies are commonly used to scale blockchain networks like Ethereum, which have transaction limitations. However, Linus believes the most exciting application of BitVM is scaling Bitcoin to handle millions of transactions and becoming the most widely used currency globally.
BitVM’s Compatibility with Bitcoin
An appealing aspect of the BitVM proposal is its compatibility with Bitcoin today, without requiring any additional soft forks. Soft forks can be challenging to implement and may take years to execute successfully. By executing smart contracts “off chain,” BitVM prevents congestion on Bitcoin’s limited space. The proposal allows for complex computations between parties without leaving a trace on the blockchain unless a dispute arises. This off-chain execution concept is similar to the Lightning Network’s approach to scaling Bitcoin transactions.
Skepticism and Future Development
While there is excitement surrounding BitVM, some Bitcoin developers remain skeptical. Concerns include potential verification overhead when executing computations on-chain and the high level of interactivity required between parties. However, Linus believes these challenges can be overcome with time and further development. He sees BitVM as a starting point to spark interest and believes complete solutions will emerge in the future, opening up new possibilities for Bitcoin’s design space.
Hot Take: BitVM Could Revolutionize Bitcoin’s Capabilities
Bitcoin has long sought to enhance its smart contract capabilities to compete with Ethereum. If successful, BitVM could be the breakthrough that enables developers to build more sophisticated applications on the Bitcoin network. While skepticism exists within the developer community, BitVM’s proposal offers an innovative approach to off-chain execution and scaling Bitcoin’s transaction capacity. The potential applications of sidechains and rollups further highlight the versatility of BitVM. As development progresses, it remains to be seen whether BitVM will fulfill its promise and propel Bitcoin into a new era of functionality and adoption.
