The Pentagon\u2019s blue sky projects agency laid the groundwork for everything from the internet to driverless cars, and continues to explore the edges of technologies such as battlefield autonomy and paradigm-shifting cheap space launches. All of which makes a recent DARPA request for information on blockchain almost an indictment of the technology itself. If DARPA can\u2019t figure out a responsible, value-generating use for blockchain, who can?<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">People or organizations with ideas about how the national security community can use blockchain (or, as DARPA puts it, \u201cpermissionless distributed consensus protocols\u201d) are invited to <a href=\"https:\/\/www.fbo.gov\/index?s=opportunity&#038;mode=form&#038;id=0de0f789b3f1782b6030a044b55fb006&#038;tab=core&#038;_cview=0\" target=_blank>respond to the request<\/a> until Dec. 20, and if selected, may present their ideas at a workshop in February.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">So what, exactly, is DARPA looking for? The most common use case for a blockchain is in cryptocurrency, like bitcoin. The cryptographic protocol creates a ledger, which tracks the full record of transactions and makes it extremely difficult to falsify improperly generated inputs. (I find this explainer <a href=\"https:\/\/thenib.com\/what-is-the-blockchain\" target=_blank>in comic form<\/a> helpful). In the coin iteration, these units are then exchanged as a kind of currency, though the variability of price at a moment makes it something more like an <a href=\"https:\/\/arstechnica.com\/tech-policy\/2018\/06\/bitcoin-has-lost-more-than-half-its-value-since-last-years-all-time-high\/\" target=_blank>unstable commodity<\/a> than a reliable store of value.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">But DARPA is steering clear of currency-like uses. Currency has been a natural outgrowth of blockchain technologies because it provides the clearest incentive for many people to maintain a distributed ledger: keep running the computers doing the math to track cryptocurrency exchanges, and the exchange will periodically reward one ledger maintainer with new units of currency. (Commonly, this is what \u201cmining for bitcoin\u201d means, and it uses enough computing power to have its own <a href=\"https:\/\/motherboard.vice.com\/en_us\/article\/neganb\/bitcoin-mining-could-raise-global-temperatures-by-2-c\" target=\"_blank\">trackable environmental impact<\/a>).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Stay with me.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Rather than wade into the world of cyrptocoins, DARPA is side-stepping it, which means one of the big challenges for any blockchain application they might find value in is encouraging people to use it. The request specifies that \u201c all means of rewarding participants (e.g., giving them access to computing resources) also constitute a transfer of value; such transfers are within scope of this topic as long as rewards do not consist of money.\u201d So one possible way to distribute the ledger may literally be distributing the ledger, giving people computers to use and maintain on the condition that they keep the ledger program running.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The second topic for DARPA\u2019s blockchain workshop is no less ambitious than the first. DARPA\u2019s looking for methods that can combine economic notions of utility with the computer science world\u2019s understanding of protocol participants as \u201chonest\u201d or \u201cmalicious.\u201d If someone has an idea about how people seeking to maximize their benefit from the use of an open ledger can be kept from acting maliciously in that space, DARPA is all ears.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Finally, DARPA is also looking for analysis of the way that distributed protocols tend to centralize, and the vulnerabilities that this centralization can bring. In the case of existing blockchain cryptocurrencies, for example, it is third-party services that manage the cryptocoins of others through password-gated systems that are often hacked and stolen from. Ways to anticipate centralization and mitigate the risks could help keep a blockchain system as secure as the individual pieces in it.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">With so much uncertainty, vulnerability, and weirdness baked into the concept, it\u2019s hard to imagine the exact utility DARPA wants to get from blockchain. And that\u2019s partly the purpose of the workshop. Acknowledging that this technology has undergone real refinement and development thanks to blockchains and cryptocurrency, the agency is keeping an open mind about what, if any, function the military can glean from this work.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cThese technologies have dramatic implications for the security and resilience of critical data storage and computation tasks, including for the Department of Defense \u201d read the request. \u201cAt the same time, the concrete applications and security of these technologies for the DoD is unclear.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The agency is soliciting ideas for ways to use distributed cryptographic ledgers for things other than currency.<\/p>\n","protected":false},"author":7,"featured_media":69271,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_yoast_wpseo_meta-robots-noindex":"","_yoast_wpseo_meta-robots-nofollow":"","_yoast_wpseo_canonical":"","_acf":"","_yoast_wpseo_primary_category":8,"_jetpack_feature_clip_id":0,"_jetpack_memberships_contains_paid_content":false,"footnotes":"","_smg_distribution_targets":[]},"categories":[8,106,29,32],"tags":[],"coauthors":[3021],"class_list":["post-22508","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-c2-comms","category-daily-brief","category-home","category-newsletters"],"acf":{"subheadline":"","legacy_arc_id":"X3DCLQAQI5H6LIAYNBAX6OVISI","arc_canonical_url":"\/c2-comms\/2018\/12\/06\/darpa-wants-to-know-if-it-can-do-anything-with-blockchain\/","remove_feature_photo":false,"is_sponsored":false,"subtype":"","redirect_url":"","disable_inline_ads":false,"native_logo_pretext":"Presented By:"},"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v26.0 (Yoast SEO v28.1) - https:\/\/yoast.com\/product\/yoast-seo-premium-wordpress\/ -->\n<title>DARPA wants to know if it can do anything with blockchain - C4ISRNet<\/title>\n<meta name=\"description\" content=\"The agency is soliciting ideas for ways to use distributed cryptographic ledgers for things other than currency.\" \/>\n<meta name=\"robots\" content=\"noindex, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"DARPA wants to know if it can do anything with blockchain\" \/>\n<meta property=\"og:description\" content=\"The agency is soliciting ideas for ways to use distributed cryptographic ledgers for things other than currency.\" \/>\n<meta property=\"og:url\" content=\"https:\/\/one.sightlinemg.com\/c4isrnet\/c2-comms\/2018\/12\/06\/darpa-wants-to-know-if-it-can-do-anything-with-blockchain\/\" \/>\n<meta property=\"og:site_name\" content=\"C4ISRNet\" \/>\n<meta property=\"article:published_time\" content=\"2018-12-06T00:57:34+00:00\" \/>\n<meta property=\"article:modified_time\" content=\"2026-08-08T18:05:57+00:00\" \/>\n<meta name=\"author\" content=\"Kelsey D.
