Aqua Protocol Version 1.2

Introduction

Please find version 1.1 here [LINK TBD].

Major changes to version 1.1:

Change the way how verification of siganture and witness events work. They are now part of the currently written revision and always force that a new revision which is created. Verification hashes for signatures and witness events are included into the new forced written revision. This was necessary to avoid unresolvable conflicts which could be created by divergant forks of an aqua-chain in two distinct containers after sharing the original chain.

Version 1.2 was used to pilot and prototype the aqua-guardian. A security compontent being used to exchange data between two or more aqua-containers (Personal-knowledge-containers) by doing access control and policy enforcement for data acccess agreements.

System Components

Core Components
