With Ethereum (ETH) switching from a Proof-of-Work to a Proof-of-Stake (PoS) consensus - scheduled for September 19 - there has been a marked increase in the network hashrate for Ethereum Classic (ETC), which will not convert to the PoS algorithm.

According to data from 2miners.com, the network hashrate for ETC has more than doubled since mid-July, from around 20 Th/s to its current rate of 47 Th/s - a new all-time high.

Ethereum Classic is the legacy chain of Ethereum, after a hard fork was created in 2016 following a split in the community over whether to revert to the chain or move to a new one following a major hack.

More than 11.5 million ETH was stolen - around $50 million at the time and $19 billion today - and there was a bitter dispute over the resolution.

Vitalik Buterin and Gavin Wood, who created Ethereum, led the move to the new Ethereum, which has since become the top altcoin on the market, while some original ETH investors stayed loyal to the original chain.

They argued that a new fork went again decentralization and what ETH had originally set out to do - stop things being manipulated by individual people or groups.

The fork turned out to be a smart move by ETH, which has since become the top altcoin on the market - and may flip Bitcoin - reaching an all-time high of nearly $5,000 per token and currently trading at $1,700.

ETC, on the other hand, has never broken $200, and has drifted between the top 20 and top 30 coins.

It has also been the subject of a series of '51% Attacks' (where a group of miners can alter the blockchain) leading to low investor confidence.

However, miners are now
