arweave · permanent storage

BlockyVSDouble-Spend Dan
Blocky saysArweave offers permanent storage — pay once, stored "forever" via an endowment model.

Where IPFS needs ongoing pinning, Arweave aims for permanence: a one-time fee funds an endowment that pays for storage indefinitely as costs fall. It's a blockchain-like "permaweb" for data. Good for content that must never disappear (NFT media, archives, immutable web pages). The trade-off is trusting the endowment economics to hold over decades.
