TODA enables low-cost cryptographic digital files that travel with physical goods — proving authenticity, ownership, and chain of custody from manufacturer to end recipient. No blockchain complexity. No connectivity required. Tusculum is the licensed commercialization partner bringing TODA to enterprise and government markets.
Customers need confirmation that goods received are genuine parts from acceptable sources.
Full shipping history from production to receipt — every step — for less than $1.00 per purchase.
Customs and regulators require tamper-evident confirmation of compliance with export regulations.
Digital files today cannot prove uniqueness, who created them, or who owns them — validity is trapped in decades-old rigid paradigms.
Blockchain-based solutions impose gas fees, server costs, and connectivity requirements that make high-volume, low-value tracking economically unviable.
Each TODA asset carries its history and rules with it. Provenance and integrity are an inherent part of the asset's lifecycle — not an add-on, not a database lookup, not a third-party attestation.
A TODA file is created at the factory, customs warehouse, or any trusted point in the supply chain. It embeds quantity, description, issuer identity, and rules — all cryptographically signed.
Each shipper, warehouse, and distributor transfers the file using TODA. The new owner is recorded in the file itself. Transfer costs pennies and settles in under 60 seconds.
Wholesale quantities break down into retail units. A 10,000-unit file fragments into individual packages — each fragment carries the full provenance of the original. The sum always equals the original.
End recipients drag and drop the TODA file into the free Verifier app. They see issuer, every prior owner, current owner, quantity, and data integrity — all without connectivity or database access.
Databases are powerful tools — but they rely on trust in a central authority. TODA makes the asset itself the source of truth, removing that dependency entirely.
Databases enable easy updates or deletions. While useful for many applications, it's not ideal where historical data must remain unchanged for legal, auditing, or trust purposes. TODA creates immutable transaction logs, cheaply and efficiently.
In a traditional database, altering past records can be done without a clear trail if not properly logged. TODA's cryptographic approach ensures any alteration is immediately evident — changing all subsequent records would be practically infeasible.
Databases can log changes, but don't provide a mechanism for third-party verification of data integrity. TODA allows anyone to verify the history of data independently, quickly, without database access — increasing security by an order of magnitude.
For micropayments or supply chain tracking where millions of small transactions need high integrity with minimal delay, traditional databases do not scale as effectively. TODA processes 1 million transactions per hour at negligible system cost.
TODA is a data protocol, founded in 2017 in Toronto and Cambridge, that works with any digital file to create a unique asset that can be owned — and proven, without connectivity.
Each asset carries its history and rules with it. Identity, prior owners, current owner, and data integrity are embedded — not stored externally.
How it's stored, shared, and used stays under your control. TODA uses SHA-2 for cryptographic digests and ECDSA for signing — proven standards, not proprietary lock-in.
Move data from one service to another without losing integrity or ownership. Works across different platforms and systems without lock-in to any single provider.
TODA uses scripts within transactions to enforce conditions for asset transfer — multi-signature requirements, conditional payments — with no blockchain fees.
Computational costs are borne by the devices making changes. Running TODA does not require constant growth in servers. One million transactions per hour, for pennies.
The following represent the industries where TODA's provenance and integrity capabilities deliver the clearest value. Tusculum is actively seeking pilot partners in each of these sectors.
A digital bill of lading that travels with every drug shipment from manufacturer to patient. Any patient can verify authenticity on their phone. Under $1 per package — viable at scale in low-income markets.
HEALTHCARE · AFRICA · GLOBALTODA can track fuel provenance from depot to vehicle or aircraft — fragmenting records as fuel is dispensed. Prevents maintenance failures from contaminated batches. Functions fully offline.
ENERGY · LOGISTICSTODA can verify provenance of agricultural goods from remote growing regions to processor — without continuous connectivity. Regulators and buyers see a complete, tamper-evident record.
AGRICULTURE · TRADETODA can provide regulators with tamper-evident, verifiable records of every transfer in a shipment's history — export compliance, customs declarations, and ESG reporting in a single file.
TRADE · REGULATORYTODA can prove that components came from certified suppliers and maintain warranty and compliance records that cannot be falsified — embedded in the part's file from the moment of manufacture.
MANUFACTURING · COMPLIANCELuxury goods solve counterfeiting with physical seals, watermarks, and special packaging — effective, but cost-prohibitive for a $2 malaria tablet. TODA would create a low-cost cryptographic file that does what a Rolex box does for a $10 medicine package.
The solution must: cost under 5% of retail price, allow any buyer to verify on their own device, and function in low-connectivity environments. TODA meets all three requirements.
TODA's offline-first design means assets can be created, transferred, and verified anywhere — remote forests, agricultural fields, contested supply routes, or island communities. When connectivity returns, records reconcile automatically and completely.
Field teams operating in areas without connectivity can create verified TODA records at the point of activity — no internet required. Each record is cryptographically bound, timestamped, and immutable. When connectivity is restored, records integrate automatically — providing auditors and buyers with tamper-evident proof of exactly what occurred, where, and when.
Track fuel and goods from origin to final recipient — fragmenting records as quantities are distributed. Every transfer is logged in the asset itself. Auditors and regulators see a complete, unfalsifiable chain of custody without needing access to a central database.
When no network is available, TODA transfers via Bluetooth or physical media between devices. Local relay nodes settle all transfers and sync to central systems when connectivity returns — updates measured in kilobytes, not megabytes.
Tusculum is the licensed commercialization partner for TODA Protocol — developed since 2017 with Cambridge CRDC, UCL, and ARM. We are currently onboarding pilot partners across pharmaceutical supply chain, agricultural provenance, logistics, and field recording.
If your organization has an integrity or provenance challenge at scale, we'd like to understand it and design a pilot program with you.
