After the ban on ICO and crypto trading in China, local investors moved to the South Korean market, whose representatives call this trend dangerous for their own companies, Business Korea reports.

A lot of sites financed from China, including Zeniex, OK Coin and Gate. io, settled in South Korea. Zeniex, for example, receives investment from China's largest cybersecurity company Qihoo 360 and is connected with the crypto-currency media companies Bishije and Jinse Chaijing. The 18th largest exchange in the world Gate. io is also a Chinese site, which now operates from South Korea. Last month, OK Coin came to this market.

Trade in crypto-currencies and their popularity continue to be on the rise in South Korea, while in this country there are no strict rules for the registration of exchanges, which makes it an attractive jurisdiction for Chinese businesses looking for opportunities near home.

While the ban on holding the ICO in China remains in force, the National Assembly of South Korea officially proposed to lift similar restrictions on Tuesday.

Chinese virtual currency exchanges are not yet competitive, but they are key players in the global market. If the Korean virtual money market moves into the system and Chinese exchanges receive real name accounts in the future, the Chinese exchanges will become a big threat to Korean exchanges

While the influence of investors from China continues to grow, experts are wondering whether foreign companies will push out local exchanges from the market unless regulators take appropriate measures.

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   212

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.
