Arweave

A blockchain-backed storage network that pays once and stores forever — used by NFT projects and protocols that need permanent, hash-addressed data.

Arweave is designed around "pay once, store forever". Users pay an upfront fee that funds an endowment, and miners are incentivized to keep data available for as long as the network exists.

Unlike IPFS, where someone must actively pin data, Arweave's economic model attempts to make persistence the default. NFT projects, RSS mirrors, and protocols (e.g. Mirror.xyz for posts, Bundlr for batched uploads) use it as their long-term storage layer.
