The Defense Advanced Research Projects Agency (DARPA) is trying to better understand the blockchains without authorization, but Bitcoin does not seem to be invited to the party.
To gain this insight into blockchain technology, the US Department of Defense agency sent an information request (RFI) on consent protocols distributed without permission, particularly touching aspects that have been inadequately analyzed.
An area where DARPA is trying to get better management of how blockchains without authorization can work in the absence of monetary incentives. With distributed protocols without authorization such as Bitcoin offering compensation to participants (miners) in the form of newly created coins for their work in adding blocks and ensuring network security, DARPA is interested in alternative methods that can be employed.
For the agency, it is mandatory that these techniques do not offer incentives to participants in monetary, cryptocurrency or other form. However, other transfers of value can be considered, for example by offering participants access to IT resources.
Security model based on the economy
From RFI, DARPA is also looking for a deeper insight into the idea that participants in distributed protocols without authorization will care about their economic interests. In this regard, the DoD agency is interested in "methods that exploit rigorous economic notions to advance safety theories for distributed and unlicensed computing protocols".
Furthermore, DARPA is also seeking the means by which the involuntary or intentional centralization of a distributed consent protocol can be analyzed and / or addressed. This is due to the fact that the protocols distributed without authorization may have certain aspects that are centralized and this may affect the security of the protocol, regardless of the theoretical guarantees.
According to DARPA, the information provided by rescuers could potentially inform a future agency program:
"For the purposes of this RFI, DARPA is only interested in consent protocols distributed without permission … While there is a significant amount of research and development supported publicly and privately in distributed consent protocols, DARPA seeks information along several less explored ways. of distribution without consent protocols This information could help to inform a future DARPA program. "
Blockchain-based messaging platform
Despite being a military agency that maintains a high level of secrecy in some projects, this is not the first time that DARPA has publicly shown interest in blockchain technology. Two years ago, CCN reported that DARPA was working on a communication platform where messages would be transferred to a secure decentralized protocol.
At the time, DARPA indicated that the messaging platform would be used to broadcast troop movements, especially in denied communication environments. As the DoD agency said at the time, such a blockchain messaging system would need to be resilient during cyberattacks, possess self-destructive message functions and be able to provide deniability or repudiation, if and when necessary .
