Everyone in the cryptosphere has heard the cliche criticism that PoW blockchains are destroying the earth while PoS blockchain preserves it. However, the world is not that simple and the rules are not too obvious.

A research report by the Crypto Carbon Ratings Institute (CCRI) examined 6 altcoins that use the PoS consensus mechanism to compare their power consumption.

As it turns out, the difference really is huge.

The most eco-friendly polkadot

The CCRI report examined Cardano, Polkadot, Solana, Tezos, Avalanche, and Alogrand to assess total power consumption and carbon emissions for a year.

It is not surprising that different altcoins have advantages in different ways. While Polkadot reportedly uses the least power per year, Cardano uses the least power per node. According to the study, Solana uses the least electricity per transaction, while Polkadot has the lowest carbon footprint per year.

In its report, CCRI states:

“The average US household uses about 10,600 kWh per year. Therefore, the grid that consumes the least amount of electricity, Polkadot, consumes about 6.6 times more and the grid that consumes the most electricity, Solana, consumes about 200 times (US Energy Information Administration, 2021).”

While investors and traders want to explore the greenest network on a holistic basis, such thinking is seen as too simplistic. In order to compare even 6 different altcoins, CCRI had to analyze many metrics and conditions like the minimum hardware requirements of each blockchain, node power consumption, network power consumption and other information like transaction data.

With all of this in mind, the CCRI results are the researchers’ best estimate after looking at a range of variables, as opposed to stable data.

Polkadot has passed many stages of analysis and has been concluded that it is the least harmful network for the environment. The Protocol’s Twitter account also has tweet Congratulations on that.

However, it should be noted that the numbers are not all-inclusive. Many other factors such as the location of most nodes, energy differences between countries and even the founding team’s efforts to offset carbon emissions make a big difference in how these values ​​are delivered.

Eco-friendly NFT?

Normally, conservation groups seem to make society happier and less fussy, but there are always exceptions. At the end of January, the World Wide Fund for Nature in the United Kingdom (WWF UK) announced Token for Nature NFT collection to raise awareness of endangered animals.

Although WWF UK assures its supporters that its “green” NFT is built on the Polygon blockchain, many people firmly believe that no blockchain can do anything positive and extreme for the environment.
