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.
