Your records.
Permanent. Forever.
Store documents, credentials, and contracts on-chain. Tamper-proof. Verifiable by anyone. Survives even if we shut down.
Built on Cryptographic Truth
Every record is verifiable without trusting HealChain. The proof lives on-chain.
Why HealChain
Built Different.
Built to Last.
Traditional storage fails silently. HealChain encodes your data mathematically so it can always be reconstructed — even when parts are lost.
Data splits into shards with mathematical redundancy. Lose up to 4 of 14 shards and your data is fully recoverable — the same technology used by NASA and RAID storage.
Reed-Solomon encoding runs as native precompiles in our custom go-ethereum fork — orders of magnitude faster than pure Solidity implementations.
Three independent oracles watch the chain and race to fulfill store requests. No single point of failure. Geographic redundancy across Nuremberg, Hillsboro, and AWS.
The application is open source and served from healchain.org — fast, reliable, and permanently archived on IPFS. No accounts. No servers. No trust required.
Connect your wallet and sign transactions directly. Your data is linked to your wallet address. You own it. No intermediaries hold your keys.
Data is compressed before RS encoding — up to 80% size reduction on typical text and JSON payloads. Smaller storage footprint, lower costs.
Data Integrity
Double-Layer Security:
Reed-Solomon + ci-sha4096
HealChain doesn't just survive data loss — it verifies every byte. Our proprietary ci-sha4096 integrity layer works alongside Reed-Solomon to deliver both self-healing redundancy and mathematical proof that your data is intact.
Data splits into 14 shards (10 data + 4 parity) using RS mathematics. Any 10 of 14 shards reconstructs the original — surviving the simultaneous loss of up to 4 nodes, chains, or storage locations.
After Reed-Solomon reconstructs your data, ci-sha4096 generates a 4096-bit (512-byte) cryptographic digest — significantly larger and more collision-resistant than SHA-512. Mathematical proof that recovered data is 100% identical to the original.
Reed-Solomon can reconstruct data from partial shards — but cannot detect subtle bit-level corruption or tampering that leaves shard counts intact. You get the data back, but can't confirm it's original.
Every recovery is followed by a cryptographic verification pass. The 4096-bit digest computed at store time is compared against the recovered data. Any discrepancy — even a single flipped bit — is detected immediately.
HealChain defaults to 10+4 Reed-Solomon coding — optimized for the best balance of storage efficiency and redundancy. For higher-security workloads, the parity shard count is configurable at store time, giving institutions control over the redundancy-to-storage tradeoff.
The Process
How HealChain Works
Connect your wallet and submit data. Your browser signs the transaction directly — no intermediary holds your keys.
Data is gzip compressed, then Reed-Solomon encoded into 14 shards (10 data + 4 parity) by the oracle network.
Encoded shards are stored permanently on Ethereum. Verified, immutable, and publicly auditable on Etherscan.
Retrieve by record ID at any time. Even if shards are damaged or lost, RS mathematics reconstructs your original data.
Solutions
Store Anything. Forever.
From nurses proving their license to truckers at a roadside inspection — permanent storage for the records that matter.
Real World Assets
Infrastructure Built for
Institutional-Grade Storage
As tokenized real-world assets move on-chain, the documents, records, and compliance data behind them demand storage that cannot fail. HealChain provides mathematically guaranteed data survival for the next generation of RWA infrastructure.
For RWA Issuers
Why Asset Issuers
Choose HealChain
Tokenized bonds, real estate deeds, carbon credits, and trade finance instruments all require documents that must remain accessible for years or decades. HealChain provides the only decentralized storage layer with mathematical guarantees of data survival — not just uptime promises.

A one-time $5 activation fee is required to create a paid account — includes 50 GB storage + 100 GB healing credit.
Every operation carries a transparent network service fee based on the size and complexity of the data. Encoding 40 GB requires proportionally more oracle compute than 40 MB — the fee reflects this honestly. Always shown before confirmation. No hidden charges.
Want to experiment safely? Testnet credit packs ($1–$2) let you test the full flow without affecting production oracles.
Prices shown are projected targets for when paid tiers launch. We will provide at least 30 days notice before any pricing changes. · ⬡ View on GitHub
