Summary

Base64URL is used throughout sidetree, in many cases, as a substitute for canonicalization...

Motivation

"Although Base64 is a relatively efficient way of encoding binary data it will, on average still increase the file size for more than 25%."

Requirements

Data structure file size should be minimized.

Technical Proposal

Replace Base64URL with JCS.

Granted, I wrote these tests in 10 minutes... https://github.com/OR13/jcs-vs-base64url

I welcome a counter proposal on the performance / storage side of this debate.

Done.
