Arweave

A decentralized storage network that seeks to offer a platform for the indefinite storage of data.

Arweave uses a novel blockchain-like structure called a 'Blockweave' and a consensus mechanism called 'Proof of Access' to enable permanent data storage. Users pay a one-time upfront fee to store data for at least 200 years. This makes it ideal for digital archives, history, and legally binding documents.
