Due to a volatility and returns pressure during recent months, Quantum Project has decided to merge with a crypto exchange Tokens.net. To complete the merge process, Quantum QAU token will be automatically swapped into Tokens.net DTR token. The exchange will publish an address on June 15 that will automatically convert QAU token for DTR and return them to the sender's address in a corresponding amount.

As the merge occurred effectively on June 1, Quantum Project ceased to exist. Conversion will be active June 15 through September 15. The rate is set at 1 QAU : 3.9 DTR. Tokens.net aims to deliver transparency, safety and reliability. DTR (Dynamic Trading Rights) is a deflationary token that the exchange would buy back for proceeds generated from trading fees on its exchange.

Price-wise, Tokens.net market characteristics at the moment of publication are as follows:

Average price 0.050310 USD
Market cap 60,475,059 USD
Volume (24H) 8,542 USD

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   982

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.
