SatoshiVM releases SVMZK toolkit, aiming to improve the efficiency of Bitcoin Layer 2 transaction verification

On January 26th, the Bitcoin Layer2 project SatoshiVM introduced its non-interactive zero-knowledge proof toolkit - SVMZK. SVMZK allows the prover to prove various relationships to the verifier, such as addition, subtraction, multiplication, division, or their comparisons, given commitments such as [a], [b], [c], etc.

To address the possibility of transaction order adjustments in Layer2 blocks, SatoshiVM introduced SVMZK to efficiently submit concise results to the Bitcoin network. Through the subtraction and comparison algorithms in SVMZK, the legitimacy of packed transactions in Layer2 blocks can be verified by comparing the number of transactions in the sequencer and verifier memory pools. SVMZK's features also prevent collusion between the prover and verifier.

As a key component of the entire framework, SatoshiVM has open-sourced the algorithm implementation details of SVMZK this time. However, the integration of SVMZK with Bitcoin Taproot is still under development, and this part of the code will be open-sourced at some point in the future.
