Cardano founder Charles Hoskinson has criticized the decentralized computing platform Ethereum Classic (ETC), calling it a scam with no plan of action or vision. Hoskinson's comments came in response to ETC Cooperative executive director Bob Summerwill's criticism of the programmable blockchain Ergo.

Summerwill accused Ergo Foundation of squatting on stolen goods from Charles and abandoning their own followers. Despite Ergo's absence from the upcoming Proof of Work Summit, the event will still feature prominent speakers from the crypto industry.
