What is Bool Network

An Open, Decentralized, Secure Bitcoin Verification Layer

Bool Network is a permissionless, decentralized, and secure Bitcoin verification layer that aims, within the premise of not altering Bitcoin’s consensus rules, to securely and decentralize the expansion of the Bitcoin network, thereby fostering prosperity within the Bitcoin ecosystem.

The transaction throughput of Bitcoin has long been a crucial concern for users. Despite Bitcoin’s clear advantages in security and decentralization, its limited transaction speed restricts its ability to effectively handle a large volume of transactions. This issue is an integral part of the blockchain impossible trilemma. To address this challenge, one of the primary solutions is the adoption of Layer 2 technologies. However, due to Bitcoin’s inherent lack of smart contract functionality, current Layer 2 solutions commonly encounter issues related to centralization.

To overcome these challenges, we propose Bool Network, a decentralized and secure Bitcoin verification layer driven by MPC-based distributed key management. It aims to address the constraints on Bitcoin’s transaction speed. Bool Network comprises an evolving committee of hidden members Dynamic Hidden Committees (DHC) to safeguard the identities of committee members, we introduce the Ring Verifiable Random Function (Ring VRF) protocol. In this protocol, the genuine public keys of VRF instances are concealed within a ring. Furthermore, to ensure the privacy and integrity of key components, all key management procedures are executed within a Trusted Execution Environment (TEE), such as Intel SGX. This proposal seeks to mitigate Bitcoin’s transaction speed limitations while upholding its decentralization and security.
