#walrus$WAL Off-chain encryption on Walrus is the simplest way to keep sensitive data safe while still using decentralized storage. I encrypt the file before upload, store only ciphertext on Walrus, and keep keys off-chain under clear access rules. Envelope encryption makes it scalable: the big file stays the same, but permissions change by re-wrapping a small key. The future is clear: verifiable storage with privacy by design, where users control who can decrypt and when.
