Eliminate the "trilemma" of the bullion market


Within the precious metal industry, the "trilemma" refers to the fact that it has traditionally been seen as impossible to achieve the following three objectives at the same time:

  • Ensure integrity and authenticity of the products and data

  • Achieve transparency around the products' provenance and chain of custody

  • Maintain confidentiality and privacy of business transactions and stakeholders

So far, available technology and business processes have made it challenging to fulfil the required standards in all three dimensions simultaneously and efficiently. The innovative use of new technologies, including distributed ledger technology (DLT), has enabled aXedras to build the Bullion Integrity Ledger™ and to overcome the "trilemma".
