DocuChain is a British software development and licencing company with patent applications in the UK, USA and EU.

4Trust provides a cost-effective, easily-deployed platform for licensees to define performance-based Outcomes.

Chain of Custody is 4Trust application that creates a permissioned, encrypted liaison between Physical Assets linked to Digital Twins held in an immutable Database.  Data, People and Credentials that validate the Outcome can be accessed in real time using mobile and desktop applications that are vectored to the 4Trust Portal by an Intelligent Artifact.

Chain of Value is a complementary application that permits the trustworthy exchange of Assets and Entitlements across an Integrated Value Chain.


4Trust is an encrypted, distributed platform that enterprises and public organizations with high value or mission-critical operations - which for reasons of integrity, regulation and performance - depend on trust, transparency and real-time accountability of data points from multiple sources.

4Trust delivers a consensus approach in which all trusted parties can have confidence in the data, and unlike existing solutions, uses encrypted Artifacts to authenticate physical assets alongside logical data.

An immutable blockchain or encrypted relational database record can form the basis of validating the exchange of valued goods and services between parties without needing a mechanism of trust.

4Trust provides a user defined platform for optimising business performance and ensuring best practice is followed for both internal governance and external regulation.  The Chain of Custody process is described as follows:

  • End User Access Applications compatible with Android, iOS, Windows, and websites that read the Artifact and are vectored to a secure portal. 

  • Intelligent Artifact Gateways currently NFC-powered and in a variety of form factors including documents and for embedding into components and finished products (other types of Artifacts are under test).

  • Containerised Application Portal that allows the rapid configuration of bespoke business performance applications based upon end user defined outcomes.

  • Evidentiary Data Points that are captured in the portal and that support the agreed outcomes.This includes the credentials of stakeholders and their authorised levels to execute the agreed outcomes.


4Trust can be rendered and deployed in bespoke applications using its containerised application stack.

The interface to the 4Trust portal is designed to be domain specific, and can be through smartphone, tablet or NFC-reader enabled computers. 4Trust was designed by our architects to have no single point of failure in the event of subversion or attack.

4Trust is “blockchain agnostic” and can be interfaced with any open source or enterprise private or public blockchain. 4Trust blockchains hold hashed information pointing to the location or owner of an Artifact and hashes of the temporal historical transaction records.  4Trust is also deployable into current relational databases and cloud-based infrastructure.


Several pilot projects are under development and deployment with several internationally recognised system integrators. These projects are all client-driven (versus a “technology demonstrator”) and will be migrated into revenue generating projects by our channels.

DocuChain produces an ROI analysis for every chain: IRR, NPV and Payback Period and summarised in a management dashboard.

DocuChain employs an agile, market-driven architecture for both product development and engaging with our channels and their customers. Market and technology dynamics are driving the utility of our 4Trust platform. Chain of Custody is transformational in solving business performance problems and delivering a measurable ROI to channels and end users: the title, value, location, quality, quantity and other agreed attrobutes of Assets and Entitlements in Integrated Value Chains are authenticated in real time.


DocuChain channels conduct pilots under a framework licence that is not for commercial deployments.  This allows channel partners to explore how to use 4Trust in their own client environment.  Once execution level details are agreed, the interim framework agreement can be migrated into an end-user, application-specific license with prices and terms that reflect channel and end user commercial requirements.

Our B2B model is based upon a “pay as you go” basis, which removes or minimises capex requirements.  4Trust’s flexible, containerised architecture means that customisation costs for bespoke applications are nominal.


4Trust is partnering with auditors, system integrators and other technology providers to deliver a 4Trust offering that includes both Chain of Custody, which is available today, and will roll-out its Chain of Value application later this year. Together, these two complementary applications provide a Trustworthy ecosystem that confirms Custody and allows the exchange of Value.
