The post Rootstock Prepares to Release SDKs for Bitcoin Layer 2s Using BitVMX appeared on BitcoinEthereumNews.com.

One of the oldest Bitcoin ecosystem projects is moving to the next stage of enabling developers to build layer-2 networks using its computational layer. Rootstock is one of many projects currently advancing the goal of bringing greater utility and interoperability to Bitcoin, which it is doing using “BitVMX”, a modified version of the BitVM programming language. RootstockLabs project is weeks away from releasing software development kits (SDKs), allowing developers to start producing their own Bitcoin layer-2s using BitVMX, founder Sergio Lerner told CoinDesk. SDKs are sets of tools enabling third-parties to build applications using a particular platform or framework. “We are very close to having all the pieces ready for people to start building their own solutions on top of BitVMX,” Lerner said in an interview. RootstockLabs’ BitVMX project harnesses the BitVM paradigm introduced by Robin Linus in 2023 as a design for how Ethereum-style smart contracts could be built on Bitcoin. This could then greatly improve Bitcoin’s scalability through enabling the building of faster, layer-2 networks with programmability similar to what’s possible on Ethereum and other blockchains. BitVMX Platform Alongside BitVMX contributors Fairgate, RootstockLabs last year made a breakthrough in using BitVMX to verify a zero-knowledge SNARK (Succinct Non-Interactive Argument of Knowledge), an integral aspect of cryptography in many blockchain systems. The availability of tools for other developers to explore these capabilities further will drive competition and thus increase adoption, according to Lerner. “There is a difference between a product and a platform: a product is closed but a platform is something you can easily plug in to and develop your own ideas on top of,” he said. “BitVMX is becoming a platform, which means there will be a lot more competition: rollups and sidechains competing against each other and the ones that can find use cases for people…
