BitcoinOS (BOS) Launches BitSNARK v0.2, Expanding BTC's Programmable Capabilities

BitcoinOS (BOS) has launched BitSNARK v0.2, an improved version of its protocol for verifying zero-knowledge proofs (ZKPs) on the Bitcoin network. This new technology aims to expand BTC's programmable capabilities without modifying its core protocol

BitcoinOS (BOS) has released BitSNARK v0.2, a new version of its protocol for verifying zero-knowledge proofs (ZKPs) on the Bitcoin network. The code is now available on GitHub for review and testing.

The protocol is designed to expand BTC’s programmable capabilities without modifying its core protocol. It operates through an interactive verification process between a prover and a verifier. The prover submits a ZKP to the Bitcoin blockchain, claiming that a computation was performed correctly. If the verifier has doubts about the validity of the proof, they initiate a challenge.

Using a binary search method, the specific point of disagreement in the computation is identified and resolved deterministically on the Bitcoin network. This process enables the validation of complex computations with minimal on-chain data, eliminating the need to alter BTC’s consensus protocol.

A New Set of Capabilities for Bitcoin

This new iteration, v0.2, introduces several improvements over the previous version. It can verify any computation performed in any virtual machine, in contrast to the prior version, which was limited to specific tasks.

Furthermore, it reduces the transaction size required to verify external proofs to less than 100 kilobytes, making it easier to include these transactions in regular blocks without causing issues for miners. The previous version required a larger transaction size.

The number of interactions needed to complete the verification process has also been reduced to six, increasing the protocol’s efficiency and feasibility for real-world applications.

Bridges, Rollups, Stablecoins, and More

This protocol update opens the door to applications that were previously difficult to deploy on Bitcoin. It enables trustless crypto bridges to transfer assets between BTC and other blockchains without the need for centralized intermediaries.

It also facilitates the implementation of rollups, which improve network scalability by executing thousands of off-chain transactions before settling them on the main chain.

Finally, it supports the development of programmable BTC tokens and decentralized financial applications like exchanges, BTC-backed stablecoins, and lending protocols.

With this release, BOS invites developers and community members to test and contribute to the progress of BitSNARK. The code is available on GitHub, and testing can be done on test networks with minimal setup.
