The China Center for Information and Industry Development (CCID) has released the eighth cryptocurrency asset rating. EOS is still the leader, while the newcomer Ontology, which ranks 28th at CoinMarketCap, suddenly took the fifth place. This is reported by Bitcoin.com.

In total, the new version of the rating contains 34 cryptoactives. As can be seen from the table below, EOS, Ethereum and GXChain are in the top 3. It is noteworthy that the latter occupies only the 106th line of CoinMarketCap and is traded on only a few cryptobirds.

Since the publication of the previous version of the rating, Bitcoin has rolled back from the 13th to the 18th line. According to Chinese analysts, the first cryptocurrency is surpassed by such assets as Komodo, Nebulas, BitShares, NEO, Steem, Lisk, Ark, Stellar, Waves, Ethereum Classic, Qtum and Cardano. Close the list of Litecoin, NEM and Decred.

When compiling the ranking, CCID experts rank cryptoactives according to the following criteria: basic technology, innovative potential and practical applicability. Returning to Ontology, note that the analysts highly appreciated the underlying technology of the asset.

Its [Ontology’s] main network was launched in June 2018. In this assessment, Ontology has outstanding performance in basic technology and application, with a composite index of 112.6, ranking fourth in the [overall] list.

The main goal of Ontology developers is to create a network uniting the blockchain and the real economy. The project focuses on digital identification and trust management.

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.
