The developers of Ethereum announced a delay in plans to launch Constantinople, Ethereum's upcoming system-wide upgrade, on the test network Ropsten.
Peter Szilagyi, team lead at the Ethereum Foundation, reported that the main reason for the postponement is to provide additional time for individual and corporate clients are the operators of nodes in the Ethereum network. This is due to the need to address vulnerabilities in five updates Constantinople.
In addition, the delay will allow network users Ropsten to test other projects Ethereum, for example, the off-chain scaling solution Raiden. Users will also be able to prepare for the network separation, which can happen because of the launch of Constantinople.
Requiring what is known as a "hard fork," the upgrades comprising Constantinople include changes to block reward issuance, code execution, data storage and other. The active nodes of the Ropsten testnet must simultaneously implement such changes in order to avoid separation of blockchain.
Lefteris Karapetsas, a developer for the Raiden network, said:
"Even a temporary separation of network make testing of my project is almost impossible, although he is rather close to mainnet release.".
To avoid intentionally causing complications on the ethereum testnet, the developer Alexey Akhunov a proposal to launch an alternative testnet within which it will be possible to solve obvious problems before a full test on the Ropsten network.
In accordance with the arrangement of developers and users, the release of Constantinople in the Ropsten network to be held on 14 October, almost simultaneously with the release of the block of 4.23 million.
