ProgPow algorithm upgrade looking likely

A top-level meeting with Ethereum core developers last week ended with a full agreement for the Ethereum blockchain to upgrade to the ProgPow algorithm. Followed ultimately by a move away from professional and centralized mining.

Discussions among the ETH dev community about a possible migration onto ProgPow have been ongoing for a couple of years. Although there are many critics, the Ethereum upgrade is looking ever more likely.

ASICs Equipment Dominate Ethereum Block Rewards

Since application-specific integrated circuits (ASICs) were enabled professional miners equipped with the costly mining gear have dominated the ETH block rewards, which has angered many miners who don’t own the expensive and exclusive ASICs.

This hasn’t sat well with some of the core dev team. They say it goes against the Ethereum whitepaper proposal. This aimed to keep the network optimized for low-cost and easily accessible software. With the aim of keeping mining as decentralized as possible.

Some of the core dev team claim the powerful ASICs mining machines, costly. Putting them only in the hands of the few, ‘centralizes’ the mining. This threatens network security, by heightening the possibility of a 51% attack.

After Bitmain released ASICs specifically designed for Ethereum, other GPU miners’ profits’ were pretty much nullified. This led many to demand a change in the algorithm. They also demanded a move to decentralize the mining before the launch of Ethereum 2.0.

Furthermore, there’s a controversial upgrade scheduled for June this year. The EIP-1962 upgrade will make some changes to the ETH cryptography. Then just a few weeks later it’s expected a hard fork will take place. This will likely see the more controversial ProgPow implemented.

Ethereum Upgrade Causes Split In The Ethereum Community

Of course, not everyone is happy with the move. Some Ethereum developers are against the idea an Ethereum upgrade. Many in the community have publicly shown their disapproval.

Their arguments are valid, however, as a chain split, which might see exchanges running both versions of Ethereum would be detrimental to the Ethereum brand.

Although Ethereum hard-fork coordinator James Hancock said that a split is unlikely and that ProgPoW is the most “ready to go” of the current upgrades.

I have not seen any evidence that there are an ideological or people willing to step up and actually have a network split,’ said Hancock. ‘If I’m wrong I’ll resign as hard-fork coordinator.’

Ethereum has already split once before. Many will remember the DAO hack which saw millions of ETH siphoned off after a fault in the DAO code was exploited. The Ethereum community decided to hard-fork the chain and restore all the funds to the DAO smart contract. Many were against the idea. Afterward, the dissenters kept the old chain going and formed Ethereum Classic (ETC).


Whether it’s maintaining the status quo or a move towards balancing the mining capabilities, mining is an important part of the Ethereum ecosystem. Yes, ASICs capability increases the hashrate, but because of the cost and scarcity of them, it also centralizes the power.

There will always be splits in decentralized communities and Ethereum is no different. Whatever the core devs decide on will be for the best of the whole community and not just the powerful few, and personally, I hope they implement ProgPow.
