The developers of Ethereum announced the postponement of the date of activation Constantinople to upgrade the test network Ropsten, reports CoinDesk.

The main reason for the delay is the need for additional time for the operators nod in Ethereum to respond to the vulnerabilities identified in one of five upgrades Constantinople.

Via community decision, we’ve delayed the #Ropsten Constantinople Ethereum testnet hard fork by epoch 1 to block #4230000 (+5 days) to allow clients to implement, test and release an update to CREATE2, countering a recently found EVM DoS attack vector.

Also, the developers are confident that the transfer update will allow users of the network Ropsten to test other solutions for Ethereum including technology ofcan-scale Raiden. They will also be able to prepare for a possible division circuit as a result of the implementation of Constantinople.

Upgrade Constantinople requires a hard forks and suggests a number of changes that affect the reward to the miners, code execution, data storage, etc. of the Active nodes testnet Ropsten should be ready to implement these changes at the same time, to avoid the risk of splitting the blockchain.

According to the developer network Raiden Lefteris karapetsas of even a temporary split testnet Ropsten will do further testing “almost impossible”. At the same time, he said, his project “pretty close to run in the core network”.

In order to avoid unwanted problems with testatom Ethereum, the developer Alexey Akhunov offered to run a temporary alternative to test network Ropsten. This, according to him, will help solve the most obvious problems in the code before fully testing the network Ropsten.

New launch date to upgrade Constantinople in Ropsten developers and users testnet scheduled for October 14, roughly at unit 4 230 000.

Constantinople — the second part of hard forks Metropolis. It involves changes designed to improve the performance of the Ethereum platform, to modify its monetary policy and to delay the so-called “bomb complexity.”

Note that the timing of activation Constantinople in a test already postponed before.
