Bitchat, a decentralized peer-to-peer messaging app developed by Jack Dorsey, has surged to the second spot on app charts in Jamaica as Hurricane Melissa devastates the Caribbean. The app, which facilitates internet-free, encrypted communication via Bluetooth mesh networks, has become crucial for the 2.8 million residents facing disrupted internet services. Bitchat's rise in popularity follows only the weather forecast app Zoom Earth, highlighting the urgent need for communication and weather updates during the crisis. Hurricane Melissa has claimed over 30 lives in the Caribbean, including at least 23 in Haiti, and has caused widespread destruction of homes and businesses. Bitchat's adoption reflects a growing trend of using decentralized messaging platforms in regions where internet access is compromised, whether by natural disasters or government actions. Previously, Bitchat saw increased downloads in countries like Nepal and Indonesia amid social media bans and protests.
