This notable decrease might be linked to accusations laid last week against Subhashchand Jewria, a founder of cryptocurrency known as ATC Coin. The Mumbai Police's Economic Offence Wing found out that this cryptocurrency project was an investment scheme based on a pyramid structure and coins didn't have any value outside of the ATC Coin platform.

Subhashchand Jewria worked on the project alongside with his brother, Chirag Jewria, and both of them were charged with misappropriating investor funds. The EOW’s investigation detected that Jewria earned $12.9 million USD from investments made through his pyramid scheme disguised as a cryptocoin and transferred that money to all of his 28 personal bank accounts.

It a classic case of fraud committed by floating a multi-level marketing scheme and luring investors with high returns and enviable rewards like sponsoring a foreign vacation or gifting high-end cars and also the claim that after completion of a lock-in period of 18 months, the cryptocurrency could be used for online shopping.

Jewria and his brother were accused of deceit, criminal breach of trust and criminal conspiracy in accordance with the Indian Penal Code. Law enforcement officers of Mumbai seized all their bank accounts and restored millions of rupees, which they hope to return to investors.

Potentional Vulnerabilities Found in ETH 2.0

Least Authority have found potentional security issues in the network P2P interaction and block proposal system
26 March 2020   212

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.
