Jack Dorsey Champions Bitcoin Payments on Signal via Cashu Protocol

Bitcoin advocates including Jack Dorsey and developer Peter Todd have launched the “Bitcoin for Signal” campaign urging Signal to integrate Bitcoin payments via the Cashu protocol. The proposal employs Chaumian ecash to issue blinded, redeemable tokens, enabling private, peer-to-peer Bitcoin transfers within Signal’s encrypted messaging environment. Backers such as developers Calle and Pavol Rusnak argue that adding Bitcoin payments aligns with Signal’s privacy ethos and could broaden crypto adoption. Critics, including Bitcoin contributor Peter Todd, warn that Signal’s existing MobileCoin implementation relies on too few validators, posing centralization and security risks. Opponents also note regulatory uncertainties around off-chain solutions, while some suggest integrating privacy-focused coins like Monero (XMR) or Zcash (ZEC) as alternatives. Support from Jack Dorsey follows his renewed call for tax reform on small BTC transactions, underscoring his commitment to more accessible and private Bitcoin payments. Traders should monitor upcoming technical audits, governance decisions, and regulatory feedback, as these developments may influence Bitcoin’s market dynamics and privacy-driven use cases.
