Iran’s government has cut nationwide internet access, leaving the country's crypto users in a precarious position amid widespread protests over soaring inflation and the Iranian rial’s record lows against the U.S. dollar.
Around seven million people, out of the country's 92 million population, are estimated to be crypto users, according to statista. TRM Labs tracked roughly $3.7 billion in total crypto flows in Iran between January and July 2025.
With billions of dollars in digital assets at stake, the pressing question is whether Bitcoin and other cryptocurrencies can still function when the country is virtually offline.
Despite the blackout, several technologies could allow crypto activity to continue. Starlink’s satellite internet network provides high-speed two-way connectivity by linking user dishes to orbiting satellites, offering a critical lifeline in areas cut off from terrestrial networks.
Elon Musk activated Starlink during Iran’s blackout in June 2025, and unconfirmed reports suggest similar assistance is underway now. Blockstream’s satellite network provides another solution, broadcasting the full Bitcoin blockchain globally so that transaction data can be received and verified even without traditional internet access.
In addition, decentralized mesh applications are proving vital. Jack Dorsey’s Bitchat app uses Bluetooth to relay Bitcoin transaction data peer-to-peer between nearby devices, allowing users to propagate transactions even in fully offline environments.
Downloads of the app have surged, with over 460,000 in just the past week, reflecting urgent demand amid the blackout. Meanwhile, experimental tools like Darkwire and Machankura are being developed to allow offline Bitcoin transactions using long-range radio or SMS over mobile telecom networks, further demonstrating the ingenuity of decentralized finance solutions in crisis situations.
Yet even with these innovative workarounds, one limitation remains: blockchain confirmation still requires at least one node with internet connectivity. While offline networks can propagate transactions and allow users to create and sign them, miners must ultimately see the transactions for them to be added to the blockchain.
Satellite connections and partial internet access can solve this problem, but fully disconnected networks cannot achieve complete settlement. Iran’s blackout is testing the true promise of crypto decentralization.
While Bitcoin and other digital assets can continue to move and provide financial lifelines in extreme conditions, the situation highlights that the system is not entirely independent of global connectivity.
Offline solutions demonstrate resilience and adaptability, but the ultimate dependency on some form of internet remains an inescapable reality for full blockchain functionality.
