Blockchain Identity Protocol

In the summer of 2019, I worked as a blockchain intern at Samsung Research America. My research centered around two problems:

1. Account & Identity Management systems stores on centralized servers are vulnerable to attacks (honeypots, rainbow tables to compromise low entropy passwords, insecure key management, etc)
2. Given data that exists in centralized silo’s difficult to use one’s own account/identity across different platforms.

Thus, our goal was to build a system that could manage a user’s accounts with a decentralized protocol that was not only usable across platforms but also not vulnerable to the same issues of password storage on centralized servers. Essentially a Decentralized Identity (DID).

This paper was my first in-depth research paper in crypto. The basis of this paper was eventually used by Samsung in a Patent Application. Note that this paper was written 3 years ago and significant portions of the paper are outdated (eg. Using a shard and beacon chain for scaling). Portions of the paper have been redacted.
