Buterin to Give 3000 ETH to 3 Ethereum Startups

Twitter complaints from Prysmatic Labs, ChainSafe Systems and Sigma Prime brought a lot of money from creator of Ethereum

Prysmatic Labs, ChainSafe Systems and Sigma Prime blockchain startups received unexpected donations of 1,000 ETH each (in total about $ 300,000) from the creator of Ethereum Vitalik Buterin. Thus, he supported the developers of the updated version of the Ethereum 2.0 ecosystem, complaining about the lack of funding, CoinDesk writes.

On the problems of startups Buterin learned from the Twitter thread. In particular, the co-founder of Prysmatic Labs, Preston Van Loon, who works on the scalability of the Ethereum network, said that he was not able to pay developers a full rate.

In response to this tweet, Vitalik Buterin sent 1000 ETH.

Also, thousands of ethers were received by Sigma Prime and ChainSafe, which are engaged in developing clients for Ethereum 2.0. So, co-founder of Sigma Prime, Paul Houner, attracted Buterin’s attention with a tweet about the refusal of “several grants.”

At the same time, the head of ChainSafe only said the phrase that he "literally drop out if we got $100k in ETH."

Constantinople to be Postponed

Ethereum's hardfork will be late due to critical vulnerability found
16 January 2019   196

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.
