During Series D fundraising round a $20 million investment by Mike Novogratz’s Galaxy EOS Ecosystem Fund was gained. Also there were attracted such existing investors such as Breyer Capital, IDG Capital Partners and Vulcan Capital. 

The CEO of High Fidelity, Philip Rosedale is also known as the creator of the highly popular virtual world Second Life. He is creating a blockchain infrastructure to back a billion VR customers and has already constructed a native cryptocurrency and digital-asset registry.

The High Fidelity platform is currently in beta, so it has been partly launched. The headsets that will really take us into the big consumer market are not available just yet. A lot of our early focus is on location-based facilities.

In the virtual reality, the users will access tokens regulated by a tablet-like device to purchase goods licensed by real-world merchants. Rosedale provides the scenario of a person wanting to look cool in VR acquiring a pair of Rayban sunglasses. The purchase and virtual sunglasses would then be recorded by the merchant on the EOS blockchain platform. 

The head of strategic partnerships (Galaxy Digital), Sam Englebardt claimed on the matter: 

It’s a global phenomenon that fundamentally requires a trustless consensus mechanism for currency, property and identity.

High Fidelity is aimed to enter in the Metaverse or the universe of virtual reality worlds. Rosedale ran Second Life in 2003, and this gave birth to a cryptocurrency named Linden dollars. That produced above $4 billion globally in virtual transactions. For the new virtual world, he will use blockchain to create a token called High Fidelity Coin. It is a stable coin paired to the US dollar,  the digital money will be needed to apply the VR platform.

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.
