ETC Agharta Upgrade Goes Live on Mainnet

News / 12.01.2020

On the 12th of January 2020, the Agharta upgrade of the Ethereum Classic took place on the mainnet. It occurred in block 9 573 000. There was also successful implementation of its networks, which include Morden, Morder, and Kotti. 

Likewise, the upgrade achieved the addition of Ethereum Constantinople Opcodes of Ethereum Classic, ETC mainnet. The upgrade’s objective was to make some changes in Constantinople bitwise shifting instructions, Constantinople skinny CREATOR opcode, and Onstantinople EXTCODEHASH.

Additionally, the upgrade focused on increasing the interoperability of  ETC and making ETC and ETH compatible. Before the upgrade on the 12th of January 2020, a notification from the ETC cooperative to node operators directed the latter to update their nodes. ETC Cooperative also pointed out that the upgrade was a contentious hard fork but a routine protocol upgrade.

Agharta’s Upgrade Success

According to, the syncing of over 57 % of its clients for the upgrade was successful. Bob Summerwill, executive director of ETC, commented about the number of nodes running Agharta compatible versions and considered the fork successful.

Summerwill also talked about the Classic Gethnodes, which never upgraded, saying that they were run by node operators, who spun up new nodes but kept their Classic Gethnode running until after the hard-fork when they will later get decommissioned.
