LiquidStorage for LiquidAccounts

[MrToph]

Changelog

• Added public_upload_vaccount endpoint. This endpoint can be used directly from the frontend by vaccounts. The vaccount signs the file to upload, sends it to the DSP, which verifies and stores the file. Optionally, it does some additional quota checks defined by the consumer contract: It can define max file sizes, daily global upload limits, and daily limits on a per vaccount level.
  • Added a storageconsumer contract testing the vaccount uploads + limits checking.
  • Refactored the upload_public endpoint to a common.js file as most functionality is now also required by the new upload_public_vaccount endpoint.
  • Added two quick-fix options external and boxto the sync-builtin-boxes command, because it did not work with the public zeus-sdk repo. External should be set to true when using the public repo. The default args are chosen in a way that they shouldn’t change anything if invoked as usual.

Update:

• I changed the uploads to use base64 encoding instead of hex (in both dapp-client and server) to save some bandwidth. Fixed the bytelength quota calculation

Hi, this is the initial idea that would be useful for us and hopefully for others as well. We can discuss LiquidAccount uploads based on this.

This is wonderful. Opening up internally for review. Once we have approved / made changes / declined (not likely) there, I will update here.

Thank you for your contribution.
