Prime Trust announced the launch of the cryptocurrency custody service. This is reported by the Coindesk.

It became known that as early as the middle of July, the bitcoin storage service became available to customers, and next week support for Ethereum and ERC-20 tokens will be added.

In cryptographic storages, the access key to the wallet is stored either on a secure device not connected to the network or on paper in a safe.

Recently, information has appeared that several financial market mastodons, including Goldman Sachs, Northern Trust and Intercontinental Exchange, plan to provide custodian services for cryptocurrencies. However, according to Prime Trust head Scott Purcell, they were able to get ahead of the above-mentioned organizations.

They are trillion-dollar Fortune 100 entities, and they are just not going to move that fast. "We had had an engineering breakthrough which now enables us to easily cold-storage any ERC-20 token (along with BTC and ETH, of course).

Also, Scott notes that Prime Trust will be the first company to offer any ERC-20 tokens storage services. 

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.
