HealChain uses Reed-Solomon erasure coding built into a custom Ethereum fork.
Your data survives node failures, shard loss, and chain disruptions —
and heals itself automatically.
Now live on Arbitrum One mainnet and Base mainnet. Real storage, real transactions, production-ready.
Traditional storage fails silently. HealChain encodes your data mathematically so it can always be reconstructed — even when parts are lost.
Data is split 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 local and cloud infrastructure.
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 MetaMask 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 gas costs.
HealChain doesn't just survive data loss — it verifies every byte. Our proprietary ci-sha4096 integrity layer works alongside Reed-Solomon erasure coding to deliver both self-healing redundancy and mathematical proof that your data is intact and unaltered.
Data is split into 14 shards (10 data + 4 parity) using RS mathematics. Any 10 of 14 shards can reconstruct the original — surviving the loss of up to 4 nodes, chains, or storage locations simultaneously.
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. This gives 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 malicious tampering that leaves shard counts intact. You get the data back, but you can't be certain it's the 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 and flagged immediately.
HealChain defaults to 10+4 Reed-Solomon coding — optimized for the best balance of storage efficiency and redundancy for most use cases. For higher-security workloads, the parity shard count is configurable at store time, giving institutions and enterprise users control over the redundancy-to-storage tradeoff.
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.
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.
Asset records are distributed across multiple EVM chains simultaneously. No single blockchain failure can destroy your data. Shards self-heal across Arbitrum One mainnet, Sepolia, Arbitrum, Base, Optimism, Jasmy — and expanding.
Three independent oracle nodes watch every chain 24/7. If a fulfillment fails, the next oracle picks it up automatically. Geographic redundancy across Nuremberg, Hillsboro, and AWS — no coordination, no single operator.
Every shard is stored on a public blockchain with a cryptographic hash. Recovery is deterministic and auditable — any party can independently verify data integrity without trusting HealChain or any intermediary.
Reed-Solomon 10+4 coding means data survives the loss of any 4 of 14 shards. The same mathematics used by NASA deep-space missions and enterprise RAID arrays — now available for on-chain asset records.
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.
📩 Contact PartnershipsInterested in integrating HealChain storage into your RWA issuance platform or tokenization stack? We offer enterprise partnerships, dedicated oracle infrastructure, and custom SLA arrangements.
No surprise fees. No investor pressure. A size-based network service fee reflects real oracle costs. Revenue goes directly back into expanding the network.
How Fees Work
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 being processed. 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.
