This time we will look at the recent issues with the Constantinople Hardfork.
1) Constantinople and Petersburg
In January the Constantinople Hardfork got delayed yet again due to some potential security implications of one of its EIPs.
We will look at
* what led to the postponement
* how this situation was handled by the developers
* the “Petersburg” Hardfork
* some proposed solutions for the EIP in question
* concerns about CREATE2
Afterwards feel free to chat with other cryptocurrency enthusiasts about Ethereum or whatever else you find interesting.
