Private and public media data in a decentralized system

In a computing system that is implemented in a decentralized network that implements a distributed ledger, the distributed ledger being configured to back one or more decentralized identities (DID) for one or more users of the computing system, a method for inserting media data into existing media data in a way that ensures the inserted data is not accessible to all users, the method comprising:

• receiving a first portion of media data;
• granting access to the first portion of media data to a plurality of users, the access being at least partially based on a DID that is associated with each of the plurality of users;
• and
• receiving a second portion of media data that is inserted into the first portion of media data, the second portion of media data being accessible by only a subset of the plurality of users who have access to the first portion of media data, wherein access to the second portion of media data is also at least partially based on the DID of each of the subset of users.

A computer implemented process for inserting media data into existing media data in a way that ensures the inserted data is not accessible to all users, the process comprising:

• displaying in a first user interface portion a first portion of media data generated by a first user;
• displaying in the first user interface portion a second portion of media data generated by second user;
• exposing the first user interface portion to the first and second users and to a third user, wherein the first, second, and third users are at least partially identified based on a respective decentralized identity (DID), the respective DIDs being backed by a distributed ledger of a distributed network;
• receiving input in a second user interface portion from the second user or the third user that generates a third portion of media data for insertion into the first user interface portion;
• and
• inserting the third portion of media data into the first user interface portion, wherein the third portion of media data is viewable by at least one of the second and third users, but is not viewable by the first user.
