The whole cryptocurrency society shakes due to the news from China. As reported, all the existing crypto-exchange markets in China will be closed by the end of this month.

However, it seems that China has decided to give Huobi and Okcoin an extra month of life. As reported by, the local newspaper, the fact that the exchanges lack in ICO offerings was one of the factors that allowed them to continue operating longer than others.

Because the two platforms have large numbers of users and have not performed ICO operations, the relevant departments have given Huobi and Okcoin a one-month buffer period to stay open until the end of October before shutting down. Specific proposals are still being studied.

Thereby, Bitcoin price has surged instantly, climbing around $400 in minutes from about $2,972, as detailed by

At the time of writing, the price of the top cryptocurrency is about $3287.58, its market capitalization is $54,467,185,480.

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.
