In distinction, a transaction on Tezos takes 0.0016 kWh or lower than the power required to cost an Apple Pill for 10 minutes. 100 Tezos transactions is equal to driving 10 km in a Tesla Mannequin 3. The power use of the whole Tezos community is roughly equal to 2 households within the U.S. for the entire yr. One query, although, is how competing blockchains resembling Tezos, Polkadot and Solana will carry out in the marketplace as soon as Ethereum transitions to Eth2.

In line with Cointelegraph Analysis’s unique investigation into the most energy-efficient blockchains for nonfungible tokens (NFT), the Ethereum community is at present utilizing extra power than Costa Rica does throughout a whole yr. To place this into perspective, a single transaction on Ethereum makes use of roughly 30 kilowatt-hour, which is equal to powering a home in the US for an entire day. 100 Ethereum transactions is equal to driving roughly 390 kilometers in a Tesla Mannequin 3. Nevertheless, Ethereum’s upcoming transfer to Eth2 will change all of this for the higher.

Blockchain power consumption has been topic to intense debate. Whereas NFTs are current on a number of blockchains, the brand new analysis report solely in contrast power consumption on two chains. Power consumption is straight associated to a blockchain’s consensus mechanism, the place Ethereum represents proof-of-work (PoW) and Tezos is used for instance of proof-of-stake (PoS).

The outcomes present that the Ethereum blockchain is considerably extra energy-intensive than an alternate PoS chain resembling Tezos. In 2021, transactions on Tezos have been greater than 35,000 instances extra energy-efficient than these on Ethereum.

When addressing the difficulty of power consumption, one, to begin with, wants to tell apart transaction prices and the prices of sustaining the community. Naturally, a PoW system resembling Ethereum might be extra energy-intensive than a PoS blockchain resembling Tezos.

The PoW vs. PoS debate

A PoW blockchain community relies on numerous particular person miners contributing to the community’s hash energy to be able to safe the community. Thus, the power consumption of Ethereum, for instance, isn’t straight associated to the variety of transactions. Every transaction solely contributes marginally to the overall power consumed.

Nevertheless, when evaluating power consumption throughout blockchains, it must be scaled by a metric that captures how extensively a community is used. Subsequently, the overall power consumption is split by the variety of transactions {that a} community performs inside a day. For Ethereum, the overall power consumption is a product of the common day by day hash fee and an estimate for {hardware} effectivity. Lastly, the outcomes are annualized for comparability.
