Contributions to BitVM from Bitlayer Research Team
13 Nov 2024
The Bitlayer Research Team has been an active contributor to the BitVM ecosystem, focusing on enhancing its technical capabilities and efficiency. Over the past year, we have completed several significant contributions. Below is a summary of our achievements, listed from the most recent to the earliest, showcasing our commitment to advancing the BitVM project.
2025.1.7
Bitlayer, in collaboration with Element Labs, adapts the Chunker from the ZKP verifier to the transaction graph of the Bridge, enabling the entire BitVM to function seamlessly. This effort is focused on preparing for the launch of the BitVM testnet.

2024.12.21
Bitlayer has joined the BitVM Alliance. https://bitvm.org/
2024.12.19
The Bitlayer research team has submitted a fix for the issue where non-fixed point precomputation was inconsistent across different chunks.
🔗 https://github.com/BitVM/BitVM/pull/163
2024.12.10
At the BitVM alliance meeting, an issue regarding improving the README documentation was raised. The Bitlayer team provided information about the main folders in the code repository.

2024.12.2
The Bitlayer research team has fixed a pairing computation error in the BitVM project, which could have allowed malicious challengers to succeed in challenges under any circumstances.

2024.11.6
After weeks of effort, we are thrilled to contribute the Chunker code to the official BitVM repository. The Bitlayer research team has focused on optimizing zero-knowledge proof verification, successfully contributing a big part of reducing the Groth16 verifier program. The program has been reduced from ~7GB to ~1GB through the whole effort from the community. Chunker is another significant milestone of BitVM progress, contributed by the Bitlayer research team. The Chunker divides the verifier program into 975 chunks and 1,079 intermediate values, resulting in both assert transactions and slash transactions fully compliant with Bitcoin’s consensus rules. This achievement lays a solid foundation for BitVM’s transformation from theory to practice and continues to drive innovation within the community.

2024.10.12
Released a Hint-based version of multi-scalar multiplication in affine coordinates, further reducing the cost of Groth16 verification from 1.26GB to 1.05GB.
🔗 https://github.com/BitVM/BitVM/pull/117
2024.10.11
Implemented multi-scalar multiplication in affine coordinates, increasing the efficiency of cryptographic operations.
🔗 https://github.com/BitVM/BitVM/pull/114
Introduced checks for elements within the G2 group, ensuring compliance with cryptographic standards.
🔗 https://github.com/BitVM/BitVM/pull/115
2024.7.21
Built the first version of an automatic chunker, leveraging the stack analyzer to improve data segmentation processes.
🔗 https://github.com/BitVM/rust-bitcoin-script_old/pull/5
2024.7.11
Developed a static stack usage analyzer, enabling deeper insights into stack utilization within scripts.
🔗 https://github.com/BitVM/rust-bitcoin-script_old/pull/4
2024.6.6
Achieved significant improvements in batch scalar multiplication, reducing the cost of FFLONK verification from 7.4GB to 5.6GB.
🔗 https://github.com/BitVM/BitVM/pull/73
2024.4.13
Implemented an efficient algorithm for U32 arbitrary-bit circular right shift.
🔗 https://github.com/BitVM/BitVM/pull/52
On the same day, we also introduced the initial version of the SHA256 implementation, a critical component for hashing operations in BitVM.
🔗 https://github.com/BitVM/BitVM/pull/54
2024.3.28
Optimized U30 integer addition for better performance and lower computational cost.
