Bitcoin Developers Explore ZK Proofs for DeFi Expansion Without Forks

Bitcoin developers are exploring the integration of zero-knowledge (ZK) proofs to enhance DeFi functionalities, which currently necessitates a soft fork for implementation. Edan Yago, a Bitcoin veteran, highlights the challenges of forking a blockchain valued at $2 trillion, comparing it to open-heart surgery.

Key points include:

  • A fork is a change in a blockchain's code that creates a separate path.
  • Soft forks allow interaction with older versions; hard forks do not.
  • ZK proofs enable privacy-preserving validation of statements but are not yet available on Bitcoin.
  • Proposed implementations like OP_CAT and OP_CTV could introduce ZK functionality through a fork.
  • Yago emphasizes the need for developers to find alternative methods without forking.
  • The BitSNARK protocol from BitcoinOS provides ZK verification capabilities on Bitcoin, enabling cross-chain interactions.
  • BitSNARK can compress complex computations into 300 bytes, facilitating BTCFi developments such as decentralized exchanges and BTC-backed stablecoins.

Various projects aim to implement DeFi on Bitcoin using OP_CAT or OP_CTV, but Yago advocates for achieving similar outcomes without a fork.
