Unlocking the potential of Bitcoin Layer 2s with BitVMX-enabled solutions, Rootstock releases SDKs for building scalable and innovative networks.
The development of layer-2 networks is crucial for Bitcoin’s scalability and usability. One project that has been working towards this goal is Rootstock, which recently announced its plans to release software development kits (SDKs) for building layer-2 networks using its computational layer, BitVMX.
Bitcoin's scalability refers to its ability to process a large number of transactions per second.
Currently, the network can handle around 7 transactions per second, which is limited by its block size and frequency.
To improve scalability, developers are exploring solutions such as the Lightning Network, which uses off-chain transactions to increase capacity.
Additionally, proposals like Segregated Witness (SegWit) aim to optimize block space usage.
These efforts seek to enhance user experience and reduce transaction fees.
Enabling Developer Adoption and Competition
Rootstock’s ‘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.’ The availability of tools for other developers to explore these capabilities further will drive competition, which is expected to increase adoption of layer-2 networks.
Developer adoption refers to the rate at which software developers choose and start using new tools, technologies, or platforms.
Factors influencing developer adoption include ease of use, compatibility with existing systems, and integration with development workflows.
According to a survey by Red Hat, 70% of developers prefer open-source solutions over proprietary ones.
Another study found that 60% of developers switch to new tools within the first six months of adoption.
According to ‘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.’ This sentiment highlights the importance of creating an open platform like BitVMX, which will enable developers to build their own solutions and drive innovation.

An open platform is a software framework or system that allows developers to create and deploy applications, services, or tools without restrictive licensing agreements.
It provides access to source code, APIs, and other necessary resources, enabling innovation and customization.
Open platforms foster collaboration, reduce costs, and accelerate development cycles.
Standardization and Protocol Enhancements
RootstockLabs and Fairgate have formed an alliance to expand Bitcoin’s utility using BitVMX. The ‘BitVMX Force’ initiative aims to standardize and enhance protocols for smoother soft-forks and infrastructure improvements as they occur. This collaboration between Rootstock, Fairgate, and Input | Output (IO) will bring more firepower and capacity to create a larger community.
A Path Towards ‘Money for the People’
“Sergio Lerner’s vision for Bitcoin is that it should be a ‘money for the people’ rather than just a store of value.’ He believes that creating layers like BitVMX is essential to achieving this goal. By enabling developers to build their own solutions, we can increase adoption and create new use cases for Bitcoin.
Conclusion
The release of SDKs for layer-2 networks using BitVMX marks an exciting milestone in the development of Bitcoin’s ecosystem. With the support of Rootstock, Fairgate, and Input | Output (IO), developers will have access to the tools they need to build innovative solutions on top of BitVMX. As competition increases, we can expect to see new use cases emerge for Bitcoin, bringing it closer to its original purpose as a “money for the people”.
