The present invention discloses a method and apparatus for automatically provisioning data stitching circuits within a network element. The storage server retrieves an extent identifier from a first sorted data structure, wherein the storage server uses the received file block number to traverse the first sorted data structure to the extent identifier. Additionally methods are described to allow user control of said device for the purpose of authorizing or controlling use of said device in the application of credit, debit and cash transactions, including cryptocurrency and card-to-card transactions. %, wherein the added element has an oxide formation free energy smaller than that of Cu and has a diffusion coefficient in Cu larger than the self-diffusion coefficient of Cu.
