Tech entrepreneur and former Square CEO Jack Dorsey has urged the messaging app Signal to integrate Bitcoin payments through the Cashu protocol, a move that has sparked debate within the tech community. Dorsey’s public call was met with support from key figures like Bitcoin developer Peter Todd, who highlighted concerns about Signal’s current use of MobileCoin as a payment method. Despite Dorsey’s proposal, no official technical integrations have been announced, leaving industry stakeholders in suspense. This initiative underscores growing interest in integrating cryptocurrencies into privacy-focused apps like Signal, potentially impacting the future direction of digital payments.
