Threshold Network
Threshold Network powers tBTC, the Bitcoin standard in finance and the most decentralized 1:1 tokenized BTC, enabling Bitcoin liquidity to flow seamlessly across chains without compromising on settlement finality. Built on threshold cryptography and secured by a rotating network of independent node operators, tBTC distributes control of BTC so that no single entity can act unilaterally on funds. This architecture embodies Bitcoin’s core values : trust-minimized, permissionless, and censorship-resistant, while maintaining a direct settlement path back to native Bitcoin. By bridging BTC into DeFi through a system designed to favor math over trust, tBTC establishes the foundation for secure, decentralized Bitcoin utility across multiple ecosystems. This infrastructure enables tBTC to power lending, trading, and yield across major DeFi networks.
