1. A digital asset account administrative system associated with a digital asset, the system comprising:

  • (a) a computer comprising one or more processors and computer-readable memory operatively connected to the one or more processor;

    (b) one or more first writing devices operatively connected to the computer; and

    (c) one or more second writing devices operatively connected to the computer,wherein the computer, the one or more first writing devices and the one or more second writing devices are, collectively, operatively and physically separated from any network by an air gap so that the computer is an isolated computer, andwherein the computer-readable memory stores thereon instructions that, when executed by the one or more processors, cause the one or more processors to perform the steps of;

    (i) generating, using the isolated computer, a plurality of digital asset accounts capable of holding one or more digital math-based assets that are tracked by a decentralized digital asset network that uses a decentralized electronic ledger in the form of a blockchain maintained by a plurality of physically remote computer systems;

    (ii) generating, using the isolated computer, one or more private keys and a digital asset account identifier corresponding to each of the plurality of digital asset accounts;

    (iii) associating, using the isolated computer, each of the one or more digital asset accounts with a respective reference identifier;

    (iv) dividing, using the isolated computer, at least one of the one or more private keys corresponding to each of the plurality of digital asset accounts into a plurality of private key segments, wherein two or more private key segments as a subset of the plurality of private key segments that includes less than all of the plurality of private key segments are required to regenerate the respective private key;

    (v) transmitting, from the isolated computer to the one or more first writing devices, electronic writing instructions for writing each of the plurality of private key segments and the respective reference identifier to a respective removable storage medium;

    (vi) writing, using the one or more first writing devices, each respective private key segment of the plurality of private key segments and the respective reference identifier on a respective removable storage medium according to the electronic writing instructions; and

    (vii) writing, using the one or more second writing devices operatively connected to the isolated computer, each of the digital asset account identifiers along with the corresponding reference identifier to a storage medium.
