PANews reported on October 17th that according to Cointelegraph, several Bitcoin supporters, including Jack Dorsey, are promoting Bitcoin adoption by the privacy-focused instant messaging app Signal through a new campaign called "Bitcoin for Signal." The campaign aims to integrate Bitcoin with the Cashu protocol, enabling payments within the Signal app. Dorsey posted on Platform X on Thursday and retweeted a post from anonymous Bitcoin developer Cashu, the initiator of the "Bitcoin for Signal" campaign. Bitcoin developer Peter Todd also expressed support for the campaign, hoping that Bitcoin could replace or at least expand Signal's current cryptocurrency payment solution, MobileCoin (MOB).
