During a regular video conference, Ethereum developers determined a date of Constantinople hardfork. It will take place in the main net of the second largest cryptocurrency (in terms of market capitalization).
According to ???????? ???????????????? from Parity, the hardfork will allegedly take place on January, 16th, next year. It will become known which block protocol implementation will take place on in two weeks (on November, 23rd).
First, it was planned to update the protocol in November, but it was delayed after the developers revealed several bugs within the framework of Ropsten network testing.
To recap, Ethereum developers published a draft of technical documentation for Casper solution a couple of days ago. |
