ETC Weekly #6 | ETC Prepares for Thanos
This post is specifically for ETC miners and node operators
As we move closer to the highly anticipated ECIP-1099 Thanos network upgrade, we at the ETCCooperative recommend that all node operators update their current client software as soon as possible. Any node operator using OpenEthereum or Multi-Geth will lose all node functionality as these node clients no longer support the ETC network. To anyone not running a node, using a dapp or service, or has ETC on an exchange there’s nothing for you to do.
Update your node
Update your node client immediately by installing one of the two clients below.
Recently the developers from OpenEthereum and Multi-Geth arbitrarily decided to remove support for Ethereum Classic. This means that these node clients will no longer connect to the ETC network after the Thanos upgrade.
The Thanos Hard-Fork schedule
Mordor Testnet activation
- ETC block 2,520,000
- Successfully activated on October 18th, 2020.
ETC mainnet activation
- ETC block 11,700,000
- ETA November 28th, 2020.

Users can keep stay an up to date regarding any malicious forks that occur on he mainnet using Classic.fork.fault.dev maintained by BFt. Keeping track of the network in this manner could provide a quicker response time if an attack reveals itself.
Miners
Thanos was successfully implemented on the Mordor testnet in October . For miners who wish to continue testing on Mordor use the mining software below:
- Nanominer v1.12.0
- lolMiner v.1.12
- OpenETC Pool (Upcoming — Nov 15 deadline)
Miners will need to upgrade their mining software. Below is a list of resources.
What is Thanos?
ECIP-1099, also called Thanos, is the next network upgrade on ETC. This upgrade, first known as ECIP-1043 (DAG Limit Restriction) which has since taken on a new form as ECIP-1099 (Epoch Calibration). By doubling the Ethash epoch from 30K to 60K blocks, effectively reducing the DAG limit by half. Now 3GB-4GB GPUs can now continue mining ETC, and continue to attract miners to better secure the network.
Why the Epoch Calibration?
The original parameters are proving too aggressive, resulting in obsoleting support for GPUs still in wide use today by miners.
Calibrating these parameters to better reflect today’s hardware markets and mining ecosystem will bring the DAG growth back in sync with commonly used GPUs. Allowing the DAG system to continue to serve its purpose far into the future.
At current epoch (372) the DAG size is 3.91 GB. 4GB GPUs are getting obsoleted while they still make up a significant amount of ethash hashrate. Activating this change at epoch 376 (for example), would reduce the DAG size from 3.94GB to 2.47GB. With the reduced growth rate, 4GB GPUs will remain supported for an additional 3+ years!
