Bitcoin's Next Phase: Trustless Lending, DeFi Tools Expand Utility

Bitcoin’s next phase of development, dubbed “Bitcoin Season 2,” is not merely about its price but about its potential for broader utility. This perspective was discussed on The Clear Crypto Podcast, where hosts Nathan Jeffay and Gareth Jenkinson interviewed Isabel Foxen Duke, a general partner at Unbroken Chain and a long-time Bitcoin advocate.

Duke emphasized that Bitcoin Season 2 is about exploring the various financial use cases of Bitcoin beyond its role as a digital store of value. New developments such as ordinals, runes, and decentralized financial (DeFi) tools are expanding Bitcoin’s capabilities. One significant innovation is trustless lending, which allows users to borrow against their Bitcoin without relying on third-party intermediaries. Duke highlighted that this use case is almost as important as making payments.

One solution for trustless lending involves Discreet Log Contracts (DLCs), which enable users to maintain control of their Bitcoin while using it as collateral. The smart contract logic ensures repayment, eliminating the need for a central authority. Duke explained that this system is “proven by math rather than trust.”

Another exciting development is trustless bridging, which could allow Bitcoin to interact with external computation platforms without compromising its decentralized nature. Duke envisioned a future where Bitcoin could be used as a base asset that can trustlessly plug into any financial system, marking the ultimate potential for this asset.

Jenkinson also pointed out that Bitcoin-native DeFi could provide real-world financial access to individuals who are excluded from traditional banking systems. He expressed hope that minor adjustments to the code could unlock permissionless finance for everyone, creating a more inclusive financial future.
