Parity to Update After Critical Bug Discovered

The bug could affect about 30% of the participants in the Ethereum network

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 Ethereum Client v2.0 to be Released

Developers have created Parity Ethereum exclusively for mining pools, exchanges and other infrastructure nodes

Parity Technologies has introduced a new version of the full node software for the Ethereum network called Parity Ethereum v2.0.0.

This major release comes with some notable changes. First and most importantly, Parity Ethereum is built to serve as expert software for production use and shouldn’t be considered end-user software or an “Ethereum Wallet.” It is meant for mission-critical use in mining pools, exchanges, or any other type of infrastructure or service provider.
 

Parity Team

The Parity Ethereum client is able to interact with various consensus mechanisms, provides the choice between the Ethereum virtual machine (EVM) and the WebAssembly virtual machine (WasmVM), and it supports private transactions and the creation of special lists of nodes to restrict access to certain contracts.

Moreover, users should not perceive the new version of the software as a product for the end-user or Ethereum-purse, as the developers have created Parity Ethereum exclusively for mining pools, exchanges and other infrastructure nodes. This version is specialized.

The client also lacks a graphical user interface, known as the Parity wallet.
