**This SBIR proposal is submitted using Blockchain Resources Group LLC SAMS number and Cage Code. Blockchain Resources Group is a wholly owned subsidiary of VeriTX Corp. VeriTX is a qualified Small Business. Trusted Digital Maintenance for the âBase and Depot of the Futureâ is a hands-free Augmented Reality (AR) software platform for maintenance operations providing job cards, manuals, issue reporting enabled by blockchain-based spare part ordering and tracking. Proposed solution will look at the convergence of two very powerful technologies â Augmented reality and Blockchain (append-only distributed ledger technology that provides data integrity and transparency).

We have executed multiple proofs of concept (PoCs) in the commercial aerospace market and within the DoD. Those PoCs have allowed VeriTX and Spiral Technology to ideate and mature their underpinning technologies while listening to the customers and providing to their pain points. The Defense and Commercial Aerospace supply chain challenges and pain points are almost identical which enables the proposed solution to work cross vertically. Currently, VeriTX and Spiral Technology Defense Solution is at T
