This consensus mechanism, known as Proof of Work, involves computers solving advanced equations to prove miners are using computational effort to secure the network. One of the most common criticisms of cryptocurrency is that the consensus process in which coins are minted is extremely energy-intensive. However, fewer bluechip NFTS are available on these networks.What are Non-Fungible Tokens? Learn more about NFT’s Other layer 2 networks like Avalance and Arbritrum bumble up transactions and send them back to Ethereum for validation in bulk, which harnesses economies of scale and gain leads to reduced energy costs. It uses a Proof-of-Stake (PoS) blockchain and Commit Chain connectivity to scale. Some NFT providers are already circumventing this issue of energy-inefficient NFTs by releasing them on more energy-friendly layer two networks like Polygon and Immutable X.įor example, Polygon, which is formerly known as the Matic Network, blockchain is more eco-friendly, faster, and efficient compared to Ethereum. “That would essentially mean that Ethereum’s electricity consumption will literally over a day or overnight drop to almost zero.” Michael Rauchs, a research affiliate at the Cambridge Centre for Alternative Finance, told the Verge about proof-of-stake: Ethereum 2.0 will use a more environmentally-friendly mechanism that cuts the carbon footprint of NFTS to a nominal amount. When Ethereum moves to PoS, it’s fair to say the energy costs of NFTs will drop dramatically. When you purchase an NFT, you’re buying a unique certificate of ownership, which is locked within an immutable distributed database known as the blockchain network. NFTs are a type of digital asset distributed predominantly on the Ethereum blockchainĪs is the case of Bitcoin (BTC) or Ethereum (ETH), NFTs are a type of digital asset distributed predominantly on the Ethereum blockchain. These fees can fluctuate wildly if the blockchain is congested. The Ethereum miners solving these problems charge users of the Ethereum network Gwei or gas fees. These computers essentially take turns solving computational problems, much like guessing the combination for a digital lock. This mining process requires energy-intensive computing power. That’s because Ethereum relies on the Proof-of-Work (PoW) consensus mechanism, much like Bitcoin (BTC). To put these stats in perspective, one Ethereum transaction is equal to powering an entire house for a day. The Ethereum blockchain processes over 1.123 million transactions per day. Based on analytics, as of January 1, 2022, Ethereum’s energy consumption on a worldwide basis, on an annual scale, is equal to 103.59 TWh. The mining process for Ethereum is made up of a web of mathematical computations, all of which need to be solved using raw computational power.

So minting and interacting with NFTs can leave a large carbon footprint as a result. Today, the creation (minting) of a single NFT uses 142 kWh, 83 KgCO2, while the process of transferring ownership uses 52 kWh, 30 KgCO2. Instead, their price is determined by rarity traits and demand. In short, one Bored Ape Yacht Club NFT isn’t worth the same amount as another NFT from the same collection. Even NFTs from the same collection vary in value. While each individual Bitcoin or Eth token has the same value, some NFTs are worth millions, others are worthless. NFTs emerged in 2017, today projects like CryptoPunks and Bored Ape Yacht Club have become part of internet culture. Non-Fungible Tokens (NFTs) have taken the cryptocurrency industry by storm but their popularity has led many to question why they consume so much energy and what can be done about it?
Why Do NFTs use so much energy? It’s due to the underlying blockchain’s consensus mechanism on which they are minted, which currently utilizes Proof-of-Work.
