Member of the Committee on Financial Services at the US House of Representatives, Juan Vargas, proposed the use of blockcain technology to combat the use of cryptocurrency when buying sexual services and drugs. This is reported by CoinDesk.

Juan Vargas hopes that this bill will make the scope of the cryptocurrency more transparent and improve the efficiency of the federal services.

On 11 June 2018, U.S. Congressman Juan Vargas penned the Fight Illicit Network and Detect (FIND) Trafficking Act in order to "improve the efforts of Federal agencies to impede the use of virtual currencies and online marketplaces in facilitating sex and drug trafficking."

If the US Congress takes the initiative to vote, the Office of General Accounting will conduct a study on how virtual currencies are used to support trafficking in persons, drug trafficking and other purposes.

In March, the Playboy TV network began accepting cryptocurrencies as payment for adult content. However, the work of such platforms became endangered after the US Congress passed the FOSTA-SESTA law in April, banning sex trade on the Internet.

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.
