A new quantitative analysis model launched in China

Once a new model of Beijing-based cryptocurrency exchange Huobi has been recently released, it immediately caught the attention of exchange analytics who are analysing its efficiency at the global market.

A Going by notable views at the moment,Huobi,  the First “Big Three” Chinese Exchange, has  successfully rolled out a new quantitative analysis model that may be a breakthrough  after a long-lasting freeze in China's bitcoin exchange world due to its visible at the first sight advantages such as different blockchain-based currencies and a bunch of variables.

Named SMARTChain, this promising data model is designed with support from academics of Tsinghua University. It’s eventually based on five variables for the analysis:

Blockchain

Distributed database that is used to maintain a continuously growing list of records, called blocks

  • a blockchain relevance for real-life applications;
  • its public and media attention; its trading volume;
  • its credibility and risk for inflation;
  • its technological design.

The Huobi Blockchain Research Center assumes that this high-potential model assigns scores to each blockchain in order to generate a final top-10 ranking.

The points of the world's largest cryptocurrencies  Bitcoin, Ethereum and Litecoin would respectively reach up to  88.07, 70.67 and 69.62. As for Ripple and Ethereum Classic, they could turn out to be the  fourth and fifth.

According to the tool's creators, the scores draw an approximate representation how much potential these cryptocurrencies have as a long-term investment.Interestingly, these three top tokens could also be traded along with Litecoin and Bitcoin.

Although the SMARTChain has just been launched, it is not yet certain whether this model is a robust, on-premise solution.

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.
