Thomas Lee, Fundstat Co-Founder shared information in his interview to CNBC about five indexes, that Fundstat will use to monitor different cryptocoins.

So, according to Lee, the indexes created by him are called FS Crypto FX and were created to better understand the "evolution and behavior of the cryptocurrencies" by institutional investors.

Indexes track a total of 630 different crypto-currencies, which are classified by market capitalization and trading volume into five groups:

  • FS Crypto 10 — tracks the 10 largest and most liquid digital currencies including bitcoin, ethereum, ripple, litecoin, dash, IOTA and monero.
  • FS Crypto 40 — tracks the top 11 to 50 digital currencies by market value and liquidity including NEM, bitconnect and Lisk.
  • FS Crypto 250 — tracks the top 51 to 300 cryptocurrencies by market value and liquidity including BitcoinDark, Singular DTV and FirstCoin.
  • FS Crypto 300 — tracks the 300 largest digital currencies by market value and liquidity.
  • FS Crypto Aggregate — tracks the performance of 630 digital currencies.

According to Lee, these indexes will allow investors to analyze the dynamics of various digital currencies and will perform a function similar to that performed by the S&P 500 to determine the current state of the securities market.

Fundstrat also noted that the algorithm developed by them will allow estimating the specific weight of individual crypto-currencies in each of the indices. In this case, the composition of the indices will be reviewed quarterly.

Lastly, Lee noted that even 2% of the country's currency allows to increase the yield of the traditional investment portfolio of securities, consisting mainly of stocks and bonds, by 2.29%. 

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   202

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.
