Japanese IT giant Fujitsu launched a blockchain system which gives retailers the ability to tokenize traditional promotional tools, such as coupons and reward points. This is reported by Coindesk.

The system launched in Japan can be used by shops in malls and tourist areas for promotional activities related to coupons and points. For example, when consumers receive points and coupons in one shop and can then spend them at another store.

The Fujitsu blockchain system tokenizes digital points and coupons, processing it and storing data on customer transactions in a decentralized database. According to the company, this reduces the load on traditional data centers and allows to analyze data better.

The ultimate goal of the project, according to Fujitsu, is the revitalization of regional economies - in other words, this project can be expanded to regional communities where tokenized points can circulate in facilities related to shops, restaurants, schools, transportation and tourism.

Before releasing the final version of the product, Fujitsu tested the system with various organizations, including railway and telecommunications companies, as well as convenience stores. In particular, in March the company tested its new technology in one of the branches of the Taiwanese trading network FamilyMart - the project used a distributed ledger platform for the transfer and storage of digital "stamps".

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.
