Breaches of personal data have become a fact of life in today鈥檚 digital world. The full names, Social Security numbers, birthdates, addresses, and driver's license numbers of 143 million Americans were exposed in the 2017 Equifax database breach. Just 2 years earlier, more than 20 million records of past and present government employees were stolen from .

As the default record keeper for society, governments are large targets for hackers. But rather than accept such attacks as the cost of doing business in the information era, they could be mitigated or avoided through the responsible deployment of blockchain data structures. Such data structures harden network security by reducing single-point-of-failure risk and can make attempting a breach prohibitively challenging.

Government agencies, like the Department of Homeland Security, are getting serious about blockchain applications in cybersecurity. DHS is funding blockchain startups to conduct research and development and explore new approaches to cybersecurity. According to a DHS official 鈥渂lockchain technologies have the potential to revolutionize the way we manage online identity and access the internet; this R&D project will help .鈥�

Government agencies must fulfill their mission while responsibly managing scarce resources. For government leaders walking this budget tightrope, blockchain may be a much-needed lifeline. In the right context, blockchain solutions could reduce redundancy, streamline processes, decrease audit burden, increase security, and ensure data integrity.

Take, for example, the GSA FASTLane process. This system鈥攗sed by GSA to manage incoming proposals from vendors鈥攃urrently takes 40 days to process incoming proposals, but GSA is hoping a blockchain solution can help meet a target time of 10 days. A GSA official recently stated that a blockchain solution could 鈥渓ower the direct .鈥�

To further illustrate how blockchain solutions could increase efficiency, consider the federal government鈥檚 ongoing challenge with reconciling intragovernmental transfers. At any given time, there are trillions of dollars in . The process of reconciling these funds is time consuming, expensive, and creates budget uncertainty. A payment and accounting system that used blockchain could provide a permanent audit trail and facilitate faster reconciliation.

Being a relatively new technology in practice, but more importantly, a new tradecraft, the blockchain ecosystem is quickly evolving to narrow in on use cases and collaborate to test and explore its potential. With many possibilities for ledger-based solutions, the first step is to responsibly identify viable blockchain challenges, then test and develop the corresponding solution. As blockchain matures, we anticipate new and previously unforeseen applications for the government, ultimately increasing trust, security, and efficiency for citizens.
