CCN was founded in the summer of 2013 as CryptoCoinsNews. We have been around for six years. We are (were?) the crypto-related news site with the highest amount of traffic worldwide. Although CoinDesk and Cointelegraph have been friendly competitors with us the past six years for the #1 Alexa spot.

The CCN team also noted that the June update had a negative impact on the traffic of the aforementioned CoinDesk and CoinTelegraph, the traffic of which decreased by more than 20%.

It should be noted that soon after the rebranding and the change of the name, CCN often published news that was indirectly related to the blockchain industry, for example, related to the global economy, politics, the US-China trade war, etc.

Now CCN intends to reorient its team of more than 60 people to work with the HVY journalistic platform.

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.
