Video game integration of cryptographically secured digital assets

A method of integrating a cryptographic digital asset into a digital software application, the digital software application including code that, when executed, displays a character avatar on a display associated with a user device, the character avatar being operably controlled by a user via the user device, the method comprising:

• receiving a digital asset identification (ID) code, the digital asset ID code existing together with a unique owner ID code on a distributed blockchain ledger, the digital asset ID code including a code string segmented into a series of code subsets, wherein a first plurality of the code subsets includes data indicative of a plurality of attributes of the digital asset;
• representing the cryptographic digital asset on the display, wherein the cryptographic digital asset comprises a virtual object having an appearance that is based on the first plurality of the code subsets of the digital asset ID code, the virtual object further including a plurality of object attributes;
• and
• modifying at least one of the object attributes according to an aspect of the digital software application or interaction between the character avatar and the virtual object;
• modifying at least one of the code subsets of the digital asset ID code according to an aspect of the digital software application or accomplishment of the user or character avatar within the digital software application;
• and transmitting a cryptographic block comprising the digital asset ID code with the modified at least one code subset to a distributed blockchain ledger to record the modification.
