Self-Healing Decentralized Storage

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.

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.

🧬
Reed-Solomon Erasure Coding

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.

Custom EVM Precompiles

Reed-Solomon encoding runs as native precompiles in our custom go-ethereum fork — orders of magnitude faster than pure Solidity implementations.

🔮
Multi-Oracle Network

Three independent oracles watch the chain and race to fulfill store requests. No single point of failure. Geographic redundancy across local and cloud infrastructure.

🌐
Open Frontend

The application is open source and served from healchain.org — fast, reliable, and permanently archived on IPFS. No accounts. No servers. No trust required.

🔒
Wallet-Native Signing

Connect MetaMask and sign transactions directly. Your data is linked to your wallet address. You own it. No intermediaries hold your keys.

📦
Gzip Compression

Data is compressed before RS encoding — up to 80% size reduction on typical text and JSON payloads. Smaller storage footprint, lower gas costs.

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 erasure coding to deliver both self-healing redundancy and mathematical proof that your data is intact and unaltered.

LAYER 1
🧬
Reed-Solomon Erasure Coding
Industry Standard · NASA / RAID Heritage

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.

LAYER 2
🔐
ci-sha4096 Integrity Layer
Proprietary · HealChain Internal

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.

⚠️
Without ci-sha4096

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.

With ci-sha4096

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.

Default Configuration

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.

How HealChain Works

1
Connect & Submit

Connect your wallet and submit data. Your browser signs the transaction directly — no intermediary holds your keys.

2
Compress & Encode

Data is gzip compressed, then Reed-Solomon encoded into 14 shards (10 data + 4 parity) by the oracle network.

3
Store On-Chain

Encoded shards are stored permanently on Ethereum. Verified, immutable, and publicly auditable on Etherscan.

4
Heal & Retrieve

Retrieve by record ID at any time. Even if shards are damaged or lost, RS mathematics reconstructs your original data.

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.

🔗
Multi-Chain Sharding

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.

🛡
Self-Healing Oracles

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.

Verifiable Recovery

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.

🏛
Institutional-Grade Resilience

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.

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.

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.
