# Sustainability ### 99% More Energy Efficient One of the significant criticisms of blockchains like Ethereum centers around its negative environmental impacts and high energy consumption. However, this criticism will soon be a thing of the past as the Ethereum merge fast approaches, which will transition Ethereum from a Proof-Of-Work to a Proof-Of-Stake chain. The adjustment promises to cut the Ethereum blockchain’s energy consumption by 99%. > Bloom aims to be the first NFT collection launched on this new energy-efficient chain. Regarding physical items, our goal is to herald only the highest quality and sustainably sourced materials to create limited-run physical items which will be tied to their “digital twins” on the Ethereum Blockchain so that owners can prove their authenticity and track the entire history of ownership. A luxury brand for the digital age. We believe in creating products that have a market beyond their initial sales. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
