Exploration and Prospects of BitVM Optimization

Bitcoin, as a decentralized, secure, and trustworthy digital asset, has always faced scalability issues. The UTXO model of Bitcoin makes it difficult to execute complex, state-dependent computations, limiting the scope of building decentralized applications and complex financial instruments on Bitcoin.

BitVM technology proposes a solution for achieving Turing-complete Bitcoin contracts without altering the consensus of the Bitcoin network. It utilizes Bitcoin scripts and Taproot to implement optimistic Rollup, allowing for the connection between two UTXOs in Bitcoin, thereby enabling stateful Bitcoin scripts. This greatly expands the potential use cases for Bitcoin.

However, the BitVM technology is still in its early stages, and there are some issues regarding efficiency and security. This article proposes some optimization ideas:

  1. Reduce the number of challenges based on zero-knowledge proofs to improve efficiency. ZK Fraud Proof can be constructed to achieve On-Demand ZK Proof, requiring ZK Proof only when there is a challenge.

  2. Using Winternitz single-use signatures instead of Lamport signatures can reduce BitVM's transaction fees by at least 50%.

  3. Implement Bitcoin-friendly hash functions, such as BLAKE3, to optimize script size and witness size.

  4. Introduce Scriptless Scripts, achieving logic gate commitments in BitVM circuits through Schnorr multi-signatures and adapter signatures, saving script space.

  5. Design a permissionless multi-party challenge protocol that extends BitVM's trust model to 1-of-N while addressing collusion and malicious challenge issues.

These optimization directions are expected to further improve the efficiency and security of BitVM, promoting the scalability and ecological prosperity of Bitcoin. In the future, more exploration and practice will be needed to fully unleash the potential of BitVM.
