Blockchain Technology Could Provide Secure Communications for Robot Teams

MIT Media Lab, Adam Zewe, October 5, 2021

Researchers at the Massachusetts Institute of Technology (MIT) and Spain's Polytechnic University of Madrid suggest blockchain technology could ensure secure communications for robot teams. A blockchain supplies a tamper-proof record of messages issued by robot team leaders, so follower robots can note inconsistencies in the data trail. In a simulation, data was stored in each block as a set of directions from a leader robot to followers; a malicious robot attempting to alter the content of a block changes the block hash, so the doctored block is no longer connected to the chain and false directions can be easily disregarded by followers. MIT's Eduardo Castelló said, "These techniques are useful to be able to validate, audit, and understand that the system is not going to go rogue."   ... '
