Ethereum vs. Cardano

the ultimate energy consumption breakdown

Have you ever wondered how much energy goes into running your favorite blockchain on a yearly basis?

We are aware of the enormous energy consumption of NFT marketplaces which operate on the Ethereum blockchain, and this is why our solution is built on Cardano, a third generation, energy efficient blockchain.

Artano is a platform that supports artists from all backgrounds, especially those located in regions which have limited access to exclusive galleries and art institutions. With us you don't need hundreds of dollars to create your NFT, Cardano minimizes the fees to mint an NFT and the negative impact on the environment.

We want to analyze Cardano’s and Ethereum’s yearly energy consumption, so that you can make an informed decision about which blockchain you want to support and how your activity impacts the environment. First we will analyze the yearly and single transaction energy consumption of Ethereum.

A single transaction on Ethereum

is equivalent to the CO2 footprint of 18,500+ hours of watching YouTube

or  246,480 VISA transactions...

Yearly ETH Consumption/Yearly Household Consumption

= 7,211,157

average households per year

As Ethereum uses a proof of work algorithm to execute its transactions, it requires enormous amounts of energy to execute a single transaction, which has accumulated to energy consumption of countries like Bangladesh, a top 40 consumer on a yearly basis.

It doesn't have to be this way

Proof-of-Stake solutions are superior when it comes to energy efficiency and allow you to minimize negative impact your blockchain activity has on our environment

Proof-of-Stake and Cardano

IOHK, the engineering company behind the development of the Cardano blockchain, has thoroughly studied the shortcomings of both Bitcoin and Ethereum. On the basis of scientific research and evidence-based development, Cardano has created their own Proof of Stake consensus protocol called Ouroboros -> IOHK has created their own Proof of Stake consensus protocol called Ouroboros.


This protocol has the same security aspects as the Bitcoin blockchain but instead  of miners, stake pools are participating in the protocol to solve the cryptographic puzzle to add new blocks to its chain.

Cardano Energy Consumption

*to our best estimates at this time

Number of pools

We take the total number of pools
(Total Pools = TP = 3,083)

Relays per pool

Assume the average number of relays is 3 per pool
(Relays Per Pool = RPP = 3)

System requirements

The minimum system requirements are 8GB, 2 cores, 2GHz at the moment (Minimum Specs Consumption = MS = 265W)

Consumption per year

Total consumption per year is MS * Number of hours per year (8,760h) = 2,321,400 Wh = 2,321 kWh

Powerful machines

Up the minimum requirements by 10%, as most relays run on more powerful machines
(Up Constant = 10%)

formula2

Cardano Yearly Energy Consumption Formula

TP*RPP*MS + TP*RPP*MS * 10% =

2.7 GWh

Cardano Consumes 28,000 times less energy compared to Ethereum

NFTs are not a synonym for enormous energy consumption. That’s not the impact Artano will have on the environment.

We are an NFT marketplace built on Cardano, a third generation energy efficient blockchain. This allows you to share your creativity with the world, make a living and support others through a sustainable alternative!
