Cryptographic Proof of Existence & Integrity
Blockchain-based timestamping and verification solutions. Provide cryptographic proof that your data existed in a specific state at a specific time—immutable, verifiable, and independently auditable.
Each "datacube" represents a cryptographic commitment to your data's state, anchored to the blockchain
Building verifiable truth through cryptographic precision
Prove your document, code, or data existed at a specific point in time with blockchain-anchored timestamps.
No single point of failure. Verification doesn't depend on any central authority—mathematics is the guarantor.
Batch thousands of documents into a single blockchain transaction for efficient, scalable verification.
Built for regulatory environments. Meet audit requirements with immutable proof of data integrity.
Link related documents and data states cryptographically, creating an auditable trail of changes.
Anyone can verify your timestamps without relying on our infrastructure. Trust through transparency.
Real-world solutions for verifiable data
Timestamp contracts, regulatory filings, and legal documents to prove existence and integrity. Essential for audit trails and dispute resolution.
Prove code existed in a specific state at release time. Verify the integrity of open-source dependencies and builds.
Establish prior art, prove creation dates for patents, copyrights, and trademarks without expensive registration processes.
Create tamper-evident public records, voting records, and official documents. Citizens can independently verify state actions.
Maintain immutable records of financial transactions, audit trails, and compliance documentation. Regulators can verify without accessing sensitive data.
Prove the existence of research data, datasets, and publications at specific points in time. Combat plagiarism and establish priority.
The philosophy behind cryptographic verification
"The basic premise of Bitcoin is a shared, immutable ledger, and the empowerment of everybody on the planet to audit that ledger. Since everyone can run their own node, you don't have to trust any bank, any entity, any government to know the truth." — Michael Saylor, MicroStrategy
Our timestamping solutions extend this principle to your data: verifiable truth without trusted intermediaries. When you anchor your data to the blockchain, you create proof that cannot be altered, repudiated, or lost.
Built on open standards for maximum compatibility
Our systems are designed for reliability, scalability, and transparency. All verification can be performed independently using open-source tools—no lock-in, no proprietary dependencies.
Industry-standard cryptographic hashing for data integrity
Efficient batching of thousands of documents
Ultimate immutability through proof-of-work
Decentralized content addressing for document retrieval
Building on a legacy of blockchain innovation
Our work in blockchain timestamping connects to a longer tradition of technological innovation in New Hampshire. Since 2011, the Free State and Bitcoin communities in NH have pioneered practical applications of blockchain technology.
"From weekly meetups at Manchester's Strange Brew Tavern to legislative advocacy for digital currencies, New Hampshire has been at the forefront of cryptocurrency adoption."
That same spirit drives our datacube technology: tools that empower individuals through mathematical verification rather than institutional trust.
