The first pure on-chain data storage protocol on X1 Network.
No IPFS. No Arweave. No off-chain dependencies.
The actual data lives on-chain forever.
Live proof: example permadata — 28.9MB stored for $0.000058. Decode it yourself, right now.
Four steps from data to permanent on-chain storage. No servers. No subscriptions. No trust required.
Adaptive arithmetic coding with neural probability prediction. V3 codec achieves 5–10x compression on text, up to 3,534x on structured data.
AES-256-GCM encryption with your wallet-derived key. Only you can read your data. Nobody else. Not even us.
Data is written to X1 blockchain accounts via the PermaData Anchor program. Immutable. Permanent. Verifiable.
Your permanent PDA address never changes. Read your data in 10 years, 50 years, as long as X1 exists.

Traditional storage is a subscription you can never stop paying. PermaData is a one-time write. Nobody can delete it, move it, or charge you again.

Install the SDK, connect your wallet, and you're writing permanent data to X1 in minutes. The source stays ours — you get full protocol access.
npm install @x1scroll/sdk
// npm install @x1scroll/sdk const { X1ScrollSDK } = require('@x1scroll/sdk'); const sdk = new X1ScrollSDK({ wallet: myKeypair }); // Store a document permanently on X1 const result = await sdk.store(documentBuffer, { label: 'my_document', }); console.log(result.pda); // permanent on-chain address console.log(result.cost); // fee in XNT console.log(result.compressionRatio); // e.g. 8.4x // Retrieve anytime, forever const doc = await sdk.retrieve(result.pda); console.log(doc.verified); // SHA-256 verified ✓
Text files, PDFs, and Word documents supported. Best results with text-based content up to 10MB.
Any data that matters — and needs to exist forever — belongs on PermaData.
Store every transaction receipt permanently. Audit-proof. Tamper-proof. Retrievable in 10 years.
Contracts, filings, agreements — stored with cryptographic proof of existence and content integrity.
Patient data encrypted with wallet keys. Only the patient (or authorized provider) can decrypt.
Permanent encrypted session storage for AI agents. Built into the Agent 001 Protocol.
Store the actual asset data on-chain — not just a pointer to a server that might go down.
SOX, HIPAA, GDPR archival — immutable audit trail at a fraction of enterprise storage costs.
The PermaData program is open source and deployed on X1 Mainnet. Verify everything yourself.
