Ethereum Constantinople HardforkHardfork
– a fundamental change in the source code, incompatible with the old protocol and the used software.Details took place yesterday evening. Closer to midnight, when the 7,280,000 block was mined, along with the Constantinople Hardfork , the Ethereum St. Petersburg Hardfork was simultaneously launched.
As planned St. Petersburg has disabled the updated EIP1283 protocol, which in January of this year was recognized as a "vulnerability" of the Ethereum blockchainBlockchain
is a continuous and sequential block chain of information (digital linked list). When building a blockchain, copies of related blocks are simultaneously stored on multiple computers.Details network. According to the information on our website, EIP1283 was first tested a month ago and caused the "re-entry attack" error. About what protocols were updated during Hardfork, Cryptobit.Media was already written several hours before the update.

How it was – Ethereum Constantinople Hardfork
Even though the test version of Hardfork was not entirely successful, the branching itself was distinguished by a "smooth and painless" process.
As you know, during the tests EIP1283 update caused many problems. Then the technical vulnerabilities of the blockchain network were discovered. The protocol, which was supposed to reduce the amount of gas used on the blockchain platform, gave several failures. Initially, EIP1283 was characterized as: "This EIP offers clean gas metering changes for SSTORE's opcode, which allows new storage methods to be used under the contract and reduce excessive gas costs if this does not comply with the principles of most implementations." – Ethereum.org
Then the protocol caused problems. In orderOrder

Unfortunately, it was not possible to track the holding of Hardfork. A few hours before the beginning of the forkFork
– is the intentional use of one code base of a software project to start another. That is, changing the blockchain code to split it into two.Details, the online broadcast portal was out of order. At the same time, no problems were noticed in the "mechanism" itself.
Ethereum Hardfork was commented by Nick Johnson, a teacher at the Paris High School (ENS): "It is empirically and logically clear that, if there were problems, they are likely to manifest themselves after some time in the following blocks, rather than in the branching unit itself."
