A key technology used for virtual currencies is being researched by the Department of Defense to create more secure networks. The goal is to create tamper-proof military computer systems, including those systems used to control America’s nuclear weapons.
According to Quartz, the Defense Advanced Research Projects Agency (DARPA) is looking into using blockchain technology to create more secure military networks, allow military system administrators to determine if a network or database has been tampered with. In September, DARPA awarded a $1.8 million contract to a computer security firm to begin tests.
At its most basic, a blockchain is a decentralized ledger that keeps track of data in a database or network. It then attaches a unique, persistent code, also known as a “block,” to the asset being guarded. Each time it is viewed or altered, all authorized users with access to the asset receive new blocks that update it. Each block is chained to another block, thus “blockchain.” This tech helps Bitcoin and other virtual currencies maintain integrity across worldwide networks.
Although the technology doesn’t prevent unauthorized individuals from accessing networks, it can sound the alarm
