Decentral introduced a beta version of the multi-currency wallet Jaxx Liberty.

From the usual for many popular multi-currency wallet Jaxx Liberty features a number of new features. In particular, the 'Portfolio' module is integrated into it, allowing to monitor the dynamics of user-defined crypto-currencies for a certain period of time.

There's also a news module and a similar to the Coinmarketcap rating of the cryptocurrency market capitalization.

It is also noteworthy that the Windows wallet distribution "weighs" more than 300 MB.

Test versions of Jaxx Liberty for Android and iOS OC are available on the corresponding pages of the Play Store and the App Store. Desktop beta versions of the new wallet for Windows and Mac are also available. The Linux version and the Chrome browser extension will appear between 9 and 31 July.

According to the developers, the current version is still a little "raw" and in the near future the functionality of the wallet will be further developed and enriched with new opportunities.

We recommend that users not rely solely on the beta version of Jaxx Liberty. It is very similar to the current Jaxx, but we suggest a cautious approach towards it. Treat it the way you would treat the physical wallet you have in your pocket or purse that you carry around with you every day: don’t use the beta for large sums you’re unwilling to lose.

Final release is expected in July. 

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.
