A developer by the name “Daniel Jones” revealed he has achieved “verifiable, immutable, Proof-of-Life on the blockchain.” Jones and his team successfully used shortwave radios and blockchain technology to perform a solar-powered cryptocurrency transaction “without power, internet at location.”
The radio transmitted crypto project was conceived in response to the Call for Code Challenge, which was launched this year in a partnership by the American Red Cross, IBM, David Clark Clause, and the United Nations’ Human Rights Office.
The challenge encourages developers to unite and use their tech skills and abilities to create new technologies that would bring positive and long-lasting change across the world. More specifically, CallForCode urges developers to find disaster relief solutions with their code.
While other radio-transmitted cryptocurrency transactions have been done in the past, Jones’ project is the first to be performed entirely off-grid. The operation was executed on Burst, an open source blockchain platform that aims to connect businesses, individuals, and financial institutions.
The tools used to carry out the transaction included a portable hard drive, a solar battery pack, as well as a shortwave radio. Upon completing the project, a seemingly excited Jones tweeted from his Twitter handle @nixops saying: “It is with great honor I present to you the first $burst radio transaction. Solar powered, mesh net, and on chain…”
The solar-powered project, called “proof-of-Life,” enables individuals to send messages and perform cryptocurrency transactions on the blockchain. The off-grid method makes it possible for people to exchange digital information in a verifiable, secure, and immutable manner regardless of location.
This means that individuals in isolated disaster zones could communicate virtually with the rest of the world provided their identity can be verified. Victims of disaster who are cut off from the rest of the world could confirm their survival even when all other channels of communication aren’t functioning.
In Jones’ own words: “[The] transaction… was a multi-factor verification of Proof of Life… during a disaster… there could be cases where you may need to verify [that] someone is who they claim to be but without being able to see them… the wallet was assigned to someone who sent a transaction with the fee to show the target wallet they were “alive.” This gives us some levels of certainty, wallet seed, target wallet known, and amount + fee or message content,” Cointelegraph quoted.
Natural disaster survivors who prefer not to give up their location can still deliver a message without revealing where they are, Jones further stated.
