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%. 

Constantinople to be Postponed

Ethereum's hardfork will be late due to critical vulnerability found
16 January 2019   180

A scheduled upgrade of the Ethereum network called Constantinople was postponed indefinitely after a critical vulnerability was discovered in one of the improvements, CoinDesk reports.

This is a vulnerability in EIP-1283, which, as identified by the audit company SmartSecurity smart contracts, gave hackers the opportunity to steal user funds.

During a video conference on Tuesday with the participation of Ethereum developers and other clients and projects working on the network, it was decided to temporarily postpone the activation of the hard forks.

In particular, Vitaly Buterin, developers Hudson Jameson, Nick Johnson and Evan van Ness, as well as release manager of Parity Afri Shoedon took part in the meeting. Discussing the revealed vulnerability, they agreed that it would be impossible to eliminate it before the appointed time for hardfork (around 04:00 UTC on January 17).

A vulnerability, called a reentrancy attack, allows an attacker to repeatedly enter the same function and infinitely withdraw funds.

Imagine that my contract has a function which makes a call to another contract… If I’m a hacker and I’m able to trigger function a while the previous function was still executing, I might be able to withdraw funds.

According to him, this is a lot like the vulnerabilities that were discovered in The DAO in the summer of 2016.

Representatives of ChainSecurity also noted that up to the Constantinople hard fork, data storage on the network cost 5,000 units of gas, which exceeds the 2,300 gas usually needed to call the “transfer” and “send” functions. After the upgrade, “dirty” storage operations will cost 200 units of gas, and an attacking contract can use 2,300 gas to successfully manipulate the variables of vulnerable contracts.

New date of hardfork not yet determined.
