Two storage spaces, two purposes
Arweave blockchain — permanent
Each BPV credit engraves a deposit of up to 50 MB for life on the blockchain. Indestructible, and independent of any subscription.
Cloud vault — up to 5 GB
Your large files, encrypted (AES-256-GCM) on our servers. Handy for anchoring only the fingerprint on the blockchain and saving your credits. Available from the Instant plan. Unlike the blockchain, this storage depends on your account staying active.
No subscription is required to keep your proofs: the subscription is merely a way to buy credits. Your blockchain deposits remain permanent, no matter what.
