Is an open-source blockchain-based distributed computing platform featuring smart contract functionality, which facilitates online contractual agreements.

Vulnerability was found in the Parity wallet, with the use of it $ 30 million were stolen. Company issued a security notice about the vulnerability in the wallets version 1.5 and higher (since January 19, 2017).

At the time of publication of the article, about 150,000 ETH were stolen, which is more than $ 30 million. This data is also confirmed by the Etherscan service.

As explained by the Parity team, the problem arose as a result of an error in a separate contract with a multiplier known as wallet.sol.

According to preliminary data, the potential consequences have already been mitigated, and another 377,000 ETH were protected from theft by attackers by WhiteHat's actions by hackers.

The White-hat group was able to withdraw a broadcast of $ 76 million (and another 80 million in various tokens) from vulnerable purses to protect funds.

Parity noted this error as critical, recommending to everyone who uses multi-signature wallets to move their funds to secure addresses.

According to information from Gavin Wood, CTO of Parity at least three addresses in the Ethereum network have been compromised as a result of exploitation of the vulnerability: Edgeless Casino, Aeternity and Swarm City.

Constantinople Hardfork Code to be Included in Geth

Go-ethereum (Geth) v1.8.20 assumes that hardfork in the main Ethereum network will take place at block 7,080,000 (approx. between 14th - 19th Jan 2019)

Developers of Geth, one of the most popular clients of Ethereum, presented a new version of the software with the included code of the upcoming hard fork Constantinople.

Go-ethereum (Geth) v1.8.20 assumes that hardfork in the main Ethereum network will take place at block 7,080,000.

Consensus regarding the block number for activating hard forks was reached last week during a regular video conference of leading Ethereum developers. According to Afri Shedona, release manager of another popular client of the network Parity, a block of 7,080,000 will be mined between January 14 and 18, 2019.

At the same time, Ethereum Foundation’s head of security noted that the new version of the go-ethereum client would contain a kind of “emergency switch” that would postpone the upgrade if something went wrong.

Originally scheduled for November, the Constantinople contains a number of changes and code optimizations designed to ease the transition to the Proof-of-Stake algorithm. In particular, they include the transfer by 18 months of the so-called “bomb of complexity”, which contributes to timely upgrades, and also suggests a decrease in the reward to miners from 3 to 2 ETH for the mined block.
