ETC's Agharta hard fork upgrade is expected to take place on January 15, 2020

According to ETC Core, ETC core developers and participating ecosystem stakeholders agreed on the scope and timing of the Agharta hard fork proposal. It is reported that the upgrade range of Agharta hard fork will only include the function of Constantinople. Features other than Constantinople will not be included, but may be considered when upgrading. As of now, Multi-Geth, Parity, and Geth Classic clients have confirmed participation and support for Agharta. The Agharta hard fork is expected to be carried out on January 15, 2020, and the specific block height will be announced at the end of November. Agharta hard fork upgrades will include EIP 145 (bit-by-bit instructions in EVM), EIP 1014 (Skinny CREATE2, significantly improved state channel performance), and EIP 1052 (EXTCODEHASH opcode).
