Ethereum core developers announced a five-day delay yesterday to launch an upgrade plan for the test network Rospten in Constantinople.
Peter Szilagyi explained in a tweet too Square Foundation team leader, the main reason for the delay is to give customers more time to run using the node (or the support of individuals and businesses Square Ethernet network computer servers) to A loophole found in one of the five upgrades in Constantinople.
Via community decision, we’ve delayed the #Ethereum Ropsten testnet Constantinople hard fork by 1 epoch 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.https://t.co/q0bUyj3GfR

“After the community’s decision, we delayed the #Ethereum Ropsten testnet Constantinople hard fork for a century (to block height 4230000, +5 days) and allowed the client to implement, test and release updates to CREATE2 to Against the recently discovered EVM DoS attack vector,” Szilagyi wrote.
In addition, the delay provides Ropsten users with the ability to test other Ethereum projects (such as the offline expansion solution Raiden) to provide “some space” to prepare for the possible network disruption in Constantinople.
This upgrade will involve so-called “hard forks”. Upgrades including Constantinople include changes to rewards, code execution, data storage, etc. There are not many changes to the underlying technology, but also for future upgrades. The solution builds the infrastructure. The active node of Ropsten testnet needs to implement these changes at the same time, otherwise it may split into two separate blockchains.
Overall, the upgrade of Constantinople optimized the efficiency of the Ethereum network, reduced the operating costs of smart contracts, experimented with extended solutions for stateful channels, adjusted Gas (running Ethereum fuel) charges, and adjusted Ethernet Although the economic policy of the workshop, etc., has no major technical changes, it has laid a better foundation for the future expansion of Ethereum such as Sharding or Plasma, but the average user may not feel too much. change.
Therefore, the developer of the Raiden network, Lefteris Karapetsas, told Ethereum developers in a public forum that potential network splits were caused on Ropsten, and even temporary network splits were likely to “make their projects almost impossible to test.” “.”
In order to avoid the possible “side effects” caused by deliberately testing the Ethereum test network, another idea put forward by Ethereum core developer Alexey Akhunov is to launch a separate temporary test network to Ropsten and solve the obvious problems in the code before implementation. For further testing by existing users of the Ropsten network.
