Parity Adds Support for Private Transactions and Encrypted Contracts

The implementation of  Private Transactions lets users store, modify, and view code

Ethereum client Parity has released 1.11 Beta version, which now allows users to create encrypted contracts and transactions on-chain and warp-sync to specific blocks. 

The implementation of  Private Transactions lets users store, modify, and view code. Only those users who have permissions viewable by anyone can have access to all contracts and transactions with private transactions on public chains. Moreover, they can work with others in the open behind strong encryption.

Also, Parity has improved Warp Sync to let users get their node up to speed by downloading snapshots of the current state. The users can jump to a minimum block number to make sure they are getting the latest possible snapshot, and built-in safeguards to prevent them from falling back to normal sync methods.

The Parity Ethereum transaction queue implementation was optimized in order to increase performance significantly, and now transaction verification is done in parallel.

Previously, we have reported that Parity Technologies issued a statement, according to which they did not plan to implement EIP 999 code change that could lead to a split of the Ethereum blockchain.

Parity to Fix Serious Vulnerability

An error that could shut down the computers with ETH nodes was reported by the vice president of blockchain development at Amberdata

Parity Technologies released a new version of the client that fixed a bug that could shut down computers running Ethereum nodes.

The first to discover the vulnerability and report it to Parity was Scott Bigelow, vice president of blockchain development at Amberdata analytic startup. According to him, only a small part of Parity's customers are at risk.

There was a vulnerability that [if exploited] would cause an immediate crash of the Parity client for all its services. There is no possibility to steal funds or do other malicious things but you could shut down some portion of ethereum nodes.

Parity Technologies encouraged users to upgrade their clients to the latest version as soon as possible, especially those where the publicly available RPC and transaction history tracking module are activated.

Remote Procedure Call (RPC) is a protocol that allows you to request program data on third-party servers. In the blockchain industry, it is used to obtain information on balances at addresses, block numbers, and other information.

To date, the Parity client uses about 21% of nodes in the Ethereum network (3257, according to EtherNodes).
