Witnium. Chain.
A private blockchain network for the Witnium ecosystem
The Immutable Foundation of Digital Trust
A private enterprise blockchain network that transforms how organizations prove authenticity, maintain integrity, and establish unbreakable chains of custody for their critical digital assets.
Every time a document enters Witnium Vault, WitniumChain creates an immutable Digital Witness—a cryptographic fingerprint that proves exactly what existed, when it existed, and in what state. This witness is permanently recorded across multiple validator nodes, creating an unalterable timestamp that can verify authenticity years into the future.
When you export an Evidence Binder—a curated collection of documents—WitniumChain witnesses the entire package, creating a tamper-proof seal that proves the collection's integrity. Any attempt to modify even a single byte invalidates the entire chain, making forgery computationally impossible.
QBFT consensus provides instant transaction finality. Once recorded, your witness is immediately permanent—no waiting, no uncertainty, no reversals.
The network continues operating correctly even if some nodes fail or act maliciously. Your data integrity is protected by mathematical consensus, not trust.
As a private, permissioned network, your data never touches public blockchains. You maintain complete control over who can read, write, and validate transactions.
Unlike public blockchains, WitniumChain has no gas fees, no mining costs, and no cryptocurrency volatility. Predictable, enterprise-grade infrastructure.
When a file enters the system, a SHA-256 hash of its metadata (content hash, filename, version, timestamp, custom metadata) is created. This becomes the Data ID—a unique identifier that changes if anything about the file changes.
The Data ID is combined with a timestamp and hashed again to create the Witness ID. This witness is then signed with your organization's Ed25519 private key, creating a cryptographic signature that proves the witness came from you.
Each organization has its own WitnessRegistry smart contract deployed on WitniumChain. The witness is submitted to your contract, which validates it and stores it permanently on the blockchain with the current block number.
Multiple validator nodes independently verify and record the transaction. QBFT consensus ensures that 2f+1 validators agree (in a network of 3f+1 nodes), making the record mathematically tamper-proof without requiring trust in any single party.
When a file is updated, the new witness references the previous witness ID, creating an unbreakable chain of custody. You can trace every version back to the original, proving the complete evolution of the document.
Enterprise-grade Ethereum client maintained by the Linux Foundation. EVM-compatible, Apache 2.0 licensed, and battle-tested by major financial institutions worldwide.
Quantum Byzantine Fault Tolerant consensus based on the PBFT algorithm proven by Castro & Liskov. Provides instant finality and tolerates up to f faulty nodes in a 3f+1 network.
Solidity-based WitnessRegistry contracts provide isolated storage per organization. Each contract stores witness records with cryptographic linking to previous versions.
1000+ transactions per second, 10-second block times, ~50,000 gas per witness (~200 bytes storage). Scales horizontally by adding validator nodes.
Law firms use WitniumChain to create tamper-proof evidence binders for litigation. Every document, email, and exhibit is witnessed on the blockchain, providing cryptographic proof of authenticity that stands up in court.
Financial institutions maintain immutable audit trails for compliance documentation. Regulators can independently verify that records haven't been altered after the fact.
Organizations timestamp their innovations, designs, and trade secrets on WitniumChain, creating irrefutable proof of when intellectual property was created.
Track document authenticity through complex supply chains. Certificates, test results, and compliance documents are witnessed at each stage, creating an unbreakable chain of custody.
While WitniumChain operates as a private network for performance and privacy, we regularly anchor its state to the public Ethereum mainnet. At periodic intervals, we compute a cryptographic checkpoint of WitniumChain's current state and record it in our anchoring contract on Ethereum.
This hybrid approach combines the best of both worlds: the speed, privacy, and cost-efficiency of a private chain for day-to-day operations, with the global immutability and censorship resistance of the public Ethereum network as an ultimate backstop.
Both private and public blockchains have unique strengths. WitniumChain's architecture leverages both to create a solution that's greater than the sum of its parts.
WitniumChain's Hybrid Approach: We use the private chain for all operational transactions—fast, private, and cost-free—while periodically anchoring checkpoints to Ethereum for ultimate immutability and global verifiability. You get enterprise-grade performance with public blockchain assurance.
WitniumChain is the foundation of digital trust for organizations that can't afford to compromise on authenticity, integrity, or auditability.
Every witness. Every version. Every timestamp. Immutable. Verifiable. Forever.
