Blockchain proposed for communication in robotics

Researchers from the Massachusetts Institute of Technology and the Polytechnic University of Madrid propose using blockchain as a communication tool within the robot team. They believe that blockchain could protect the team if the robot leader was hacked.

These are mainly robot drones, which are used to fight fires, deliver goods and any other tasks that require the coordinated movement of a team in one direction. Blockchain is commonly used as a cryptocurrency registry, but, as scientists point out, it is essentially a list of data structures, or blocks, that are linked in a chain. In each block, the direction of movement from the robot leader to the followers can be recorded. If a compromised robot tries to change the contents of a block, it will change its hash, and the changed block will no longer be connected to the chain, ensuring that commands to change direction will be ignored by follower robots.

Blockchain transactions

Blockchain also provides a record of all transactions - that is, commands sent by robot leaders. This will make it possible to understand whether a leader has been hacked. For example, if five leaders of different teams send messages with a command to move north and one urges to move west, follower robots may ignore that command, contradicting the others.

The robotisation of cryptocurrencies through blockchain technology is one of the latest trends.

In the system developed by the researchers, each leading robot receives a fixed number of tokens that are used to add transactions to the chain - one token per transaction, or team. If the follower robots determine that the information in the block is false, correlating it with the information the others have sent, the leader loses a token. When the robot runs out of tokens, it can no longer send messages

Hacking robots

"We have envisaged a system where disinformation costs money. When hacked robots run out of tokens, they can no longer spread incorrect commands. This way, you can limit the number of incorrect commands to expose the hacked robot," the researchers conclude.
