Post is an application developed by Hala Systems that provided civilians a collective collaboration and sensor-based early warning system against air strikes during the protracted civil war in Syria.
active since 2016, The system became more precise and complexusing a network of sensors, artificial intelligence and blockchain technology A solid technological foundation for analyzing data on site and distributing critical warnings. Sentry now gives an average of 140 early warnings per day, so that citizens are informed of possible dangers for 7 to 10 minutes.
Include data entries for the warning system Observations and reports from people, e.g. B. Aircraft sightings in the air and sensor modules in trees or on roofscollecting acoustic data for analysis. In addition, neural network systems They search local social media for keywords that can provide further clues about the time and location of potential attacks.
Until now, Has sentry used the Ethereum blockchain network Providing a secure and distributed way to review and store the metadata attached to these various data records, including their geotags and timestamps. Furthermore, Blockchain technology was an important tool to demonstrate that input data was not tampered with later.
This is especially important as the vast amount of real-time data Hala Systems has collected on strikes and attacks could be an important source of evidence in the future for organizations seeking justice to repair war crimes. As a private company whose data retention could be problematic in this regard, Hala Systems has worked with decentralized technologies like Ethereum to ensure that the data is tamper-proof from a legal perspective.
Speaking to Cointelegraph, a representative from Hedera Hashgraph said so Hala Systems has now decided to stop using Ethereum in favor of the Hedera Consensus Serviceafter it is determined that the former is not tamper-proof enough. They declared:
“Hala Systems […] found that the probabilistic consensus (not final) [de Etherum], intelligent contracts with very variable fees and slow confirmation times were not suitable for their use case. “
Hedera’s consensus service, the company said, provides a more efficient and immutable chain of retention for data entered into the systemProof that third parties can trust who, where and what of an event.
“Hala Systems can provide real evidence and verify when and where the media originated. Every event registered in the HCS is signed with the keys of the issuing chamber and receives a time stamp agreed by the entire Hedera network. ”
In addition to its technology partnership with Hedera Hashgraph Hala Systems also works with the United Nations, the UK Foreign and Development Office, the US State Department and other State departments. In an analysis of numerous offensives in northwest Syria since 2017, it was reported that the use of the Sentry app was correlated with an “average reduction in net accident rates due to air strikes of 10 to 30%”.
The Hedera platform is led by a council of mostly private partners, including Boeing, Deutsche Telekom, Google, IBM and Nomurajust like him University College London.
