Twitter co-founder Jack Dorsey is calling on Signal Messenger to adopt Bitcoin for peer-to-peer payments, suggesting the privacy-focused messaging app should abandon its current reliance on altcoins.
“Signal should use Bitcoin for P2P payments,” Dorsey wrote in a reply on X to a post by Bitcoin developer Calle, who proposed Bitcoin as a perfect fit for Signal’s encrypted communication model. The suggestion drew support from other tech figures, including former PayPal president and current Lightspark CEO David Marcus, who wrote: “All non-transactional apps should connect to Bitcoin.”
Currently, Signal supports only one in-app payment option: Sentz, the rebranded version of MobileCoin (MTCN), a privacy-focused cryptocurrency built on Ethereum. The coin faced criticism since Signal integrated it in 2021, with questions raised about ties between Signal’s leadership and the project, as well as how it was launched and promoted.
Despite the privacy features of Sentz, Bitcoin supporters argue that its decentralized infrastructure and global liquidity make it a better fit for a messaging platform known for strong encryption and privacy-first principles.
As of now, Signal has not commented on the idea of adding Bitcoin. The messenger was founded in 2014 and has consistently promoted itself as an alternative to big tech communication tools.
Dorsey’s call also reflects a wider trend in messaging and social platforms favoring altcoins over Bitcoin. Telegram is closely linked to the Toncoin ecosystem, while Meta’s now-defunct Libra project once aimed to launch a homegrown token for payments. Even Elon Musk’s X was rumored to be exploring a native coin, though he denied those plans last year.
Dorsey, who now focuses on his Bitcoin-focused firm Block, has remained one of the most outspoken voices pushing for Bitcoin’s use as a daily currency.
Interestingly, a new theory linked Jack Dorsey to Satoshi Nakamoto after financial news editor Seán Murray compiled a list of coincidences that he believes tie the Twitter co-founder to Bitcoin’s anonymous creator.
Murray presented dates, timestamps, and cryptographic clues, arguing that Dorsey is “probably” Satoshi. However, the evidence remains circumstantial, and many in the crypto space remain skeptical.
Murray pointed out that Bitcoin’s first-ever transaction occurred on Jan. 11, which happens to be Dorsey’s mother’s birthday, while the last block mined by Satoshi on March 5, 2010, coincides with his father’s birthday.
He also claimed that Satoshi registered on the Bitcoin forum on Nov. 19—Dorsey’s own birthday—and that the original Bitcoin source code documents are all timestamped at 4 a.m., a time Dorsey once featured on his Twitter profile.
Additionally, Murray highlighted a Bitcoin address created by Satoshi that begins with “jD2m”, suggesting it could stand for “Jack Dorsey 2 Mint”, referencing Dorsey’s former San Francisco residence at 2 Mint Plaza.
