Parity to Update After Critical Bug Discovered

The bug could affect about 30% of the participants in the Ethereum network
07 June 2018   881

In a test environment, which is used by Paity, a critical error was detected and fixed. This is reported by Coindesk.

As noted by representatives of Parity Technologies, when the software was launched, synchronization hasn't started, as a result  other network participants could not recognize their transactions. The vulnerability was found in the testnet, but there was a possibility of its spread to the entire network Ethereum.

Parity urged all users to update the software to a new revised version.

It is assumed that the bug could affect about 30% of the participants of the Ethereum network, which use software from Parity. Representatives of the company claim that it was patched before reaching the node of Ethereum's network. However, network members had to update the software to eliminate the vulnerability.

Several companies, including the Bitfly Mining Pool, have already said they updated their software to a new version (1.10.6-stable or 1.11.3-beta), but the bug can still complicate the work of the blockchain with the Parity software, including for Ethereum Сlassic (ETC ) users.

The bug is related to a part of the code from EIP 86.

We missed a conditional check in our code that caused full node Parity to accept a block containing invalid transactions.

EIP 86 was planned to be used to update Ethereum last year, in particular for integration into the "account abstraction" blockchain system, which will allow transactions without the sender's signature. A full update was postponed due to its complexity, but its code was added to the Parity client.

Parity to Create Alternative Client for Zcash

New node will be written in the Rust language and will become the first alternative client for zcashd

A leading developer of ecosystem solutions for Ethereum, Parity Technologies has announced a partnership with the Zcash Foundation. As part of this cooperation, the first alternative client for the private cryptocurrency Zcash will be created.

The message notes that the new node will be written in the Rust language and will become the first alternative client for zcashd - own client of Zcash Company.

In addition, according to the Zcash Foundation, Parity's expertise in creating the implementation of network nodes in networks with multiple clients demonstrated the importance of developing communities and further decentralization.

Our technical collaboration with the Zcash Foundation will bolster the cryptocurrency as a tool for financial privacy. We’re excited to leverage the time and expertise that we’ve already invested in Parity Bitcoin, while familiarizing our engineers with zero-knowledge cryptography and building a foundation for a Polkadot Zcash bridge.

On Tuesday, March 19, the Chinese manufacturer of equipment for mining cryptocurrency Bitmain introduced the device Antminer Z11 based on a 12-nm chip. The new miner is focused on mining ZCash and other cryptocurrencies based on the Equihash algorithm, and as Bitmain claims, it is three times more powerful than its predecessor Antminer Z9 mini.
