What blockchain are The Beautiful Paintings NFTs on?

The Beautiful Paintings digital artworks (NFTs) will be minted on Ethereum, which is a decentralized blockchain platform that establishes a peer-to-peer network that securely executes and verifies application code, called smart contracts. Now that Ethereum uses Proof of Stake as the consensus algorithm, it is 99% more energy efficient than proof of work blockchains such as Bitcoin or Ethereum prior to this change. It therefore does not raise any environmental concerns.
