Chinese company Qulian Technology, which created the blockchain platform Hyperchain, announced the completion of the series B financing round, in which the company managed to attract 1.5 billion yen (234 million dollars). This is reported by Coindesk.

According to a statement that Qulian published on Sunday, Xinhu Zhongbao, a real estate and finance company, became the lead investor of the round. It announced it plans a week ago, on May 27, when it applied to the Shanghai Stock Exchange.

The document says that Xinhu Zhongbao intends to invest 1.23 billion yen ($ 192 million) in Qulian, which will be divided into 2 parts: $ 17 million will be directed to the authorized capital of the company, and $ 175 million to new shares. Thus, as a result of the transaction, the investor must receive a 49% stake in Qulian.

This is a business judgement made by the company and other co-investors based on a comprehensive evaluation of Qulian. There is a risk of a mismatch in (Qulian's) income and valuation.

Potentional Vulnerabilities Found in ETH 2.0

Least Authority have found potentional security issues in the network P2P interaction and block proposal system
26 March 2020   202

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.
