Swissport to use blockchain in their aviation services

Swissport plans to utilize blockchain in their cargo and passenger services through partnering with two blockchain-oriented companies

One of the spheres to benefit greatly from use of inherently transparent and secure blockchain technology is cargo and passenger transportation. At least that's what Swissport, a Swiss aviation services company, thinks. The company is looking into using blockchain to streamline its cargo handling and passenger service.

Swissport has partnered with Olam, a Swiss non-profit foundation, to launch a pilot of an open-source platform for the supply chain. Olam utilizes blockchain and smart contracts to record shipment information and changes of custody.

Hendrik Leyssens, head of global cargo operations at Swissport, commented that using blockchain is a bid for the future-proofing the operations, because it can speed up transactions and enhance their security, while also reducing the operational costs and overcoming the chronic lack of transparency in fragmented supply chains.

And distributed ledger usage won't to be limited just to cargo handling. Swissport plans to adopt blockchain for the passenger services, provided by the company. Partnership with Winding Tree, a blockchain-based travel platform, is a proof of that. Connecting various parties to provide traveling experience to users without resorting to “help” from multiple intermediaries is a goal of Winding Tree Foundation, and Swissport wants to explore the potential of distributing its existing travel services on the platform.

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.
