[Jack Dorsey Calls for Signal to Integrate Bitcoin Payment Functionality] Bitcoin advocate Jack Dorsey is pushing for the instant messaging app Signal to integrate Bitcoin payment functionality to enable peer-to-peer payments. According to a report by Cointelegraph, Dorsey stated on the X platform on April 9, 'Signal should use Bitcoin for P2P payments,' in response to a suggestion by Bitcoin developer Calle. Calle proposed that Bitcoin is highly suitable for Signal's secure communication platform. Currently, Signal uses the cryptocurrency Sentz (formerly MobileCoin), which is based on the Ethereum network, to provide payment services. Dorsey's initiative has garnered support from other tech leaders, including former PayPal president David Marcus, who believes all non-transactional apps should connect to Bitcoin. This call may drive Signal to reshape its crypto payment strategy.
