In connection with the extremely difficult economic situation in the country, Venezuelan authorities are considering the possibility of creating their own crypto currency. This is reported by The Merkle.

As the newspaper notes, the central bank of the country seriously thought about the creation of a national crypto currency. This measure is forced, because, according to experts, it can help to overcome hyperinflation. Together with the central bank of Venezuela, Onixcoin is working on the concept of the national crypto currency.

Also, the government of the South American country is considering various opportunities for development of mining in Venezuela.

Because of the raging hyperinflation in Venezuela cryptocurrencies are in high demand. In particular, local businessmen agree to accept even digital collector cards with Pepe frog, created on the Counterparty block-platform.

On the other hand, the Venezuelan authorities are severely suppressing the production of crypto-currency, accusing the miners of Internet fraud and the theft of electricity.

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.
