Singapore - May 31, 2024 - Cobo, a leading provider of digital asset custody solutions,  today announced a strategic partnership with B² Network, a pioneering Bitcoin Layer 2 solution. Leveraging Cobo’s co-managed Multi-Party Computation (MPC) custody solution, the collaboration aims to build an advanced Bitcoin Layer 2 infrastructure that enhances both scalability and security of the Bitcoin ecosystem.

B² Network is an innovative modular Bitcoin Layer 2 solution featuring B² Rollup, the first Bitcoin rollup based on verification commitment, and B² Hub, the first data availability (DA) layer to achieve finality on the Bitcoin network. B² Hub ensures state transitions through Data Availability Sampling (DAS) and Zero-Knowledge Sampling Checkpoints, ultimately settling on the Bitcoin network to leverage its robust security and ensure transaction legitimacy and data availability.

Through this partnership, B² Network will integrate Cobo’s state-of-the-art MPC technology to ensure the funds secured through Cobo’s technology remain non-custodial and safe. When users engage in cross-chain transactions or staking via B² Network, the staked assets secured by Cobo will be co-managed by both Cobo and B² Network, following B² Network’s predefined security risk control policies, ensuring the highest level of asset protection.

Cobo’s co-managed MPC custody solution utilizes advanced MPC technology to implement threshold signature schemes (TSS). This ensures that private key shards are individually generated, encrypted, and distributed among multiple parties in a secure manner. These parties collaboratively sign transactions while maintaining the confidentiality of their individual key shares, thereby eliminating any single point of failure. Leveraging sophisticated key sharding and encryption technology, Cobo’s co-managed MPC custody solution offers B² Network  a tailored asset protection strategy. This ensures robust defense against security threats and human errors, providing their users with unparalleled peace of mind.

“Cobo is dedicated to pushing the boundaries of what’s possible in digital asset security,” said Dr. Changhao Jiang, CTO and Co-Founder of Cobo. “Our collaboration with B² Network allows us to showcase the strengths of our co-managed MPC custody solution, and together, we aim to set new standards for security and scalability in the industry. We look forward to a fruitful partnership that will benefit the entire Bitcoin community.”
