Factom Startup to Win US DHS Grant

A grant of will help to test the platform for the protection of data from surveillance cameras and sensors of the US Border Service
18 June 2018   1001

The amount of received grant is almost $200k. This is reported by Coindesk.

The early phases of Factom's work has informed architecture choices and design decisions inherent in integrating blockchain with existing technologies. In Phase IV, Factom will deploy this technology in a realistic field environment with Customs and Border Protection (CBP) to understand its operational impacts.

Based in Texas, Factom is working on a technology that allows to integrate data from cameras and sensors into the blockchain, ensuring their security and eliminating the possibility of third-party interference or their modification. The solution will be tested on a platform with limited access to the Internet and the possibility of changing weather conditions, which will allow testing it under different scenarios.

This is the fourth grant received by Factom from DHS within the framework of the Silicon Valley Innovation Program launched by the agency, which gives technology companies the opportunity to apply for funding in excess of $ 800,000 over a 2-year period.

In addition to Factom, another 22 companies are currently developing solutions for DHS. Their field of activity includes work on products in the field of the Internet of things, unmanned aerial complexes, cybersecurity for financial services, systems for assessing passenger flows and wearable technologies.

Potentional Vulnerabilities Found in ETH 2.0

Least Authority have found potentional security issues in the network P2P interaction and block proposal system

Technology security firm Least Authority, at the request of the Ethereum Foundation, conducted an audit of the Ethereum 2.0 specifications and identified several potential vulnerabilities at once.

Least Authority said that developers need to solve problems with vulnerabilities in the network layer of peer-to-peer (P2P) interaction, as well as in the block proposal system. At the same time, the auditor noted that the specifications are "very well thought out and competent."

However, at the moment there is no large ecosystem based on PoS and using sharding in the world, so it is impossible to accurately assess the prospects for system stability.
Also, information security experts emphasized that the specifications did not pay enough attention to the description of the P2P network level and the system of records about Ethereum nodes. Vulnerability risks are also observed in the block proposal system and the messaging system between nodes.

Experts said that in the blockchains running on PoS, the choice of a new block is simple and no one can predict who will get the new block. In PoS systems, it is the block proposal system that decides whose block will fall into the blockchain, and this leads to the risk of data leakage. To solve the problem, auditors suggested using the mechanism of "Single Secret Leader Election" (SSLE).

As for the peer-to-peer exchange system, there is a danger of spam. There is no centralized node in the system that would evaluate the actions of other nodes, so a “malicious" node can spam the entire network with various messages without any special punishment. The solution to this problem may be to use special protocols for exchanging messages between nodes.
