Threshold Network
Threshold Network provides a decentralized, permissionless bridge that converts Bitcoin into tBTC, a tokenized representation usable across Ethereum and other chains. The network employs threshold signature cryptography distributed across stakers to eliminate single points of failure, enabling Bitcoin holders to participate in lending, staking, trading, and yield generation. With over $5.2 billion in accumulated bridge volume and $2.7 billion in collateralized loans enabled, tBTC has become a leading solution for unlocking Bitcoin's value in DeFi.

Problem
Bitcoin, the largest cryptocurrency by market capitalization, remains largely idle and unusable in decentralized finance due to a lack of secure, permissionless bridges to other blockchain networks. Existing solutions have proven vulnerable to centralized control and collapse, as demonstrated by the shutdown of renBTC, leaving billions of dollars in BTC stranded and inaccessible for DeFi applications.
Solution
Threshold Network provides a decentralized, permissionless bridge that converts Bitcoin into tBTC, a tokenized representation usable across Ethereum and other chains. The network employs a cryptographically secure threshold signature scheme distributed across stakers, eliminating single points of failure and centralized control. tBTC enables Bitcoin holders to participate in lending, staking, trading, and yield generation while maintaining full proof of reserves and transparency. The system includes an optimistic minting phase with Minters and Guardians to ensure security during rollout, transitioning to fully permissionless minting where stakers validate deposits via SPV proofs.
Target Audience
Primary users are DeFi protocols, institutional investors, and individual Bitcoin holders seeking to deploy BTC in yield-generating applications across Ethereum and other blockchain networks.
