Traent blockchain technology — overview for the website
What it is
Traent's blockchain is a hybrid public/private distributed ledger technology (Hybrid DLT) designed for managing business processes. It combines the best of both worlds: the privacy and performance of a private infrastructure with the public verifiability of a public blockchain — private on-demand ledgers, consensus based on cryptographic proofs instead of replication, and public notarization on a public blockchain.
Why a new approach
Traent's technology was born outside the world of cryptocurrencies and DeFi, to serve the actual needs of business processes. The initial analysis of existing solutions showed that all blockchain technologies, to varying degrees, suffer from the same limitations: high operating costs, low scalability, and trade-offs that often compromise security. Private and consortium blockchains promise better performance, but obtain it by drastically reducing the number of nodes, while keeping essentially the same underlying technology as public chains.
Traent chose instead to abandon the conventional operating principles — essential for cryptocurrencies, but superfluous or even harmful elsewhere — and to redesign the technology around the data properties businesses actually need, addressing the problems that commonly block blockchain adoption outside finance: authentication, privacy, performance, private data sharing, data removal, and usability.
Key characteristics
- Private ledgers, created on demand. Nodes of the private network create new blockchain-type ledgers instantly, in potentially unlimited number, with no network reconfiguration. The natural pattern is one ledger per thing worth tracking — a product, a supply contract, a process instance — instead of one big shared chain. More than ten thousand ledgers are managed in Traent's production environment today: proof that lightweight, on-demand ledgers work at scale in practice.
- Consensus without replication. Traditional blockchains derive their guarantees from distributing and replicating the ledger across many nodes — the root of their performance limits and operating costs. Traent's protocol replaces replication with cryptographic protocols based on Merkle consistency proofs: they build on the same data structure blockchains already rely on — the Merkle tree — but where traditional blockchains only use inclusion proofs (showing that a transaction is contained in a block), Traent employs a different, less common type of proof, not in use in traditional blockchains, that proves a ledger's entire history evolved without forks, insertions, reorderings, or removals. Data access can be restricted down to a single node — a ledger never shared with anyone — or opened to a selected group of nodes.
- Public notarization, private data. Once a day, a single write on a public blockchain makes the history of the entire ledger population tamper-evident — one transaction regardless of how many ledgers exist. The mechanism is a verifiable persistent dictionary tracking every ledger's digest; only the dictionary's digest is published, protected by one-way functions, so the data itself never leaves the private network. The scheme can even prove that no two alternative histories exist for the same ledger, and that a ledger did not exist before a certain date.
- Anyone can verify, without trusting Traent. Whoever has access to a ledger can export its data — completely or partially — enriched with cryptographic proofs. Anyone outside the network can then verify the export's provenance, integrity, and fork-free history, using only the trace on the public blockchain as support. Verification does not require joining the network, and does not require trusting Traent.
- Selective disclosure by design. Exports can omit individual pieces of data (personal information is the most common case) without breaking the verifiability of the rest; every omission leaves a visible mark, so nothing can be redacted covertly. The same ledger can serve multiple audiences — a public, essentials-only product passport alongside a detailed one for the owner — all auditable against the same public trace. This granular data removal is what makes the technology compatible with GDPR erasure and retention requirements, so data producers are never disincentivized from collecting all available information.
- No fixed block time or size. Each state transition gets its own block, with instant finality inside the private network: no waiting for block intervals, no artificial throughput ceilings.
- Usable by non-technical people. Exports are consumed through an authenticated visualization: the open-source Viewer web application (Apache-2.0) verifies an export entirely in the browser, almost instantaneously, before showing anything. A typical access pattern: a QR code printed on a product's label or packaging, scanned from a phone. Custom visualizations (Views) can be embedded in the ledger itself, making the presentation as immutable and verifiable as the data — the system guarantees provenance, integrity, and non-repudiation of both.
What makes it unique — selling points
- Public trust with total privacy. Data stays private — even confined to a single organization — yet its integrity and history are publicly verifiable by anyone. No other mainstream approach offers both at once: public chains expose data, private chains ask you to trust the consortium.
- Scalability at the granularity businesses need. One daily public transaction notarizes an unlimited number of ledgers, and creating a ledger is instant. Blockchain-grade guarantees can therefore be attached to individual products, documents, or process runs — the granularity real business processes need.
- Independent verifiability. Verification relies only on the public blockchain and open-source software — not on Traent's availability or goodwill. This also solves an often-ignored weakness of consortium blockchains: a node joining an existing ledger can verify on its own that the other participants did not rewrite history just before sharing it.
- Compatible with real-world data governance. Granular, non-covert data removal supports GDPR erasure and shared retention policies — historically the blocker for putting real business data on a blockchain.
- Scientifically validated and patented. The technology was developed through multi-year research in collaboration with academic experts, is described in eight scientific papers — including peer-reviewed conference papers and a journal article in Computer Communications (2025) — and is covered by eight international patent families. The notarization technology, Traent's most differentiating solution, was developed internally, is patented, and is not available to competitors.
- No cryptocurrency required — and no chain lock-in. Notarization uses plain transactions carrying a digest: no smart contracts, no gas-priced execution, no token economics. The design is chain-agnostic: it can target any public blockchain able to store arbitrary data in transactions — a single chain, several chains simultaneously, or even any other storage trusted to be append-only.
Positioning note
The technology was born for trustworthy business data, not for cryptocurrency or DeFi: transferable tokens are deliberately left to the public blockchains designed for them. The two worlds complement each other in asset tokenization: the token — for example an NFT representing a real-estate asset — lives on an established public blockchain, while the asset's data is managed in a Traent ledger linked to the token, with protocols that let the token holder access the data and verify it independently through Traent's technologies. Proven application patterns include supply-chain transparency and Digital Product Passports (automotive, wine), ESG reporting, fact-checking, process traceability, trustworthy AI, and real-estate tokenization.
