The US Federal Reserve is actively considering the possibility of issuing digital currency, fearing the dollar will lose its leading position in the global financial system. This was stated by President of the Federal Reserve Bank of Dallas Rob Kaplan, reports CoinDesk.

In his opinion, if a foreign government or company issues digital money that is widely recognized, this could lead to the loss of the status of the world's reserve currency by the dollar.

On the eve of the previous chairman of the Commodity Futures Trading Commission (CFTC), Christopher Giancarlo also expressed concern that the re-issuance by other countries of national currencies in digital form could lead to the dollar losing its dominant role in the world. He called for the release of a digital dollar on the blockchain.

Bank of England Governor Mark Carney said earlier that a digital currency like Facebook’s Libra can replace the dollar as a global reserve currency.

The emergence of an attractive and viable alternative to the dollar will reduce demand for US government securities, Kaplan said. This will lead to an increase in interest rates by 100 basis points (1%), which will increase the cost of servicing public debt by $ 200 billion per year.

I still think for the foreseeable future, the dollar will be the world reserve currency, we’re able to refinance our debt at relatively low rates, but I don’t think we should take that for granted.

Kaplan noted that countries subjected to sanctions or increased trade tariffs by the United States are working most actively on the digital alternative to the dollar.

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.
