Cobalt & Lithium Supplies to be Tracked With DLT

The platform will be created by the Everledger together with Circulor using Hyperledger Fabric

Everledger, a British startup, has partnered with Circulor to develop a platform based on the Hyperledger Fabric blockchain to track supply chains of cobalt and lithium.

Everledger specializes in using blockchain to combat counterfeiting of precious stones, in particular diamonds. The company’s management said it intends to expand its business using blockchain to control the supply of rare minerals used in the production of batteries.

Well-known carmaker Mercedes Benz is already using Circulor technology to track its supply of cobalt and its carbon footprint. Circulor and Everledger share a similar concept - with the help of the blockchain they control the observance of social and environmental standards in mining. Therefore, startups decided to develop a joint product.

Everledger co-founder Leanne Kemp and Circulor CEO Doug Johnson-Poensgen said their solution will work on the Hyperledger Fabric blockchain. The possibility of interacting with IBM is also being discussed.

Poensgen added that the platform will be used not only to track cobalt production in the Democratic Republic of Congo, but in different regions of the world. For example, lithium mining in the Atacama desert leads to water pollution, so the solution on the blockchain is aimed at preventing environmental disasters.

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.
