Patented Technology

Peer Ledger holds multiple US and Canadian patents for scalable Distributed Ledger Technology (DLT) - based systems and methods.



Our solutions capture bilaterally-verified data about the provenance, journey, and transformation of products to help companies ensure responsible and circular supply chains, and credible sustainability reporting.

More than Distributed Ledger Technology (DLT)

Peer Ledger’s robust, comprehensive Digital Product Passport platform solution that adds new lightweight traceability governance processes and controls in supply chains. These enable the scalable collection of high quality supplier data for accurate transparency labelling.

Our comprehensive ESG data solution leverages cloud, artificial intelligence, mobile and IoT technologies in addition to DLT. Peer Ledger is ISO/IEC 27001 certified.

Our technology is deployed via fully interconnected mobile app, web portal, and a sophisticated API.

Accurate Tracking, Anywhere in the World

Peer Ledger utilizes A-GPS, GLONASS, Galileo and BeiDou satellites to geofence sensitive locations and prevent illegal ingress or egress of materials in the upstream. 



In remote locations we have achieved accuracy within 2 meters.

Private Distributed Ledger Technology (DLT), Mobile, AI, and Cloud Technologies

While Peer Ledger leverages a private DLT for its immutability controls and digitizing assets for future proofing new efficiencies, it also uses a suite of available technologies to add further important governance controls on supply chains. Some governance controls are for independent and continuous collection and verification of ESG data between supply chain tiers. 



Peer Ledger integrates product authentication technologies from Optical AI company partners as additional veracity controls. Our controls result in high quality and high availability ESG data using a compliance-forward approach. Dealing with missing and bad historical data becomes a thing of the past. With Peer Ledger, companies and government agencies can achieve the holy grail of on-demand, accurate sustainability reporting.

Built on a Solid Foundation

Peer Ledger is implemented on Hyperledger Fabric. Since Peer Ledger is a cloud-based solution using a private blockchain off the critical path of your workflows, it can scale rapidly and will maintain company data confidentiality under enterprise security controls unlike the obvious risks associated with data exposure on public blockchains.

Peer Ledger leverages AI technologies across the product life cycle to obtain efficiencies for sustainability personnel. Mobile technologies support geo-fencing sensitive upstream and midstream supplier sites.

Energy Efficiency

Energy consumption associated with public blockchain technology is a huge environmental concern. Public blockchain solutions like Bitcoin require copious amounts of energy to perform proof-of-work transactions to add data to the ledger. Since Peer Ledger is hosted on a private distributed ledger technology, our energy consumption is comparable to other cloud-based technologies companies already in use.
