Hala Systems has stopped usage of Ethereum in favor of the Hedera Consensus Service, having found the former to be insufficiently tamper-proof.

Launched in 2016 by Hala Systems, Inc., Sentry is using a sensor network, blockchain technology, artificial intelligence to provide a strong, technological underpinning for analyzing data on the ground and distributing critical alerts. The system issues an average of 140 early warnings a day, giving notice of dangers between 7-10 minutes’ advance.

The data inputs for the warning system include individuals’ observations and reports, like sightings of overhead aircraft, and sensor modules placed in trees or on rooftops, which collect acoustic data for analysis. Neural network systems trawl local social media for keywords that can provide further clues as to the timing and locations of possible attacks.

The trove of data Hala Systems has gathered in real time on strikes and attacks could, in the future, be a significant source of evidence for organizations seeking justice to redress war crimes.
