Release summary

Simple overview

Technical overview

What is this release able to demonstrate?

History and rollback

• Clients should be able to save the current state of RSpace in the form of a checkpoint (root hash of a given Merkle Patricia Trie)
• Clients should be able to reset the state of RSpace to a given checkpoint.
• Possibly out of scope: Provide a mechanism for clients to have access to the state (leaves) at a a given checkpoint.  This is needed in order to allow new validators to join an existing network.

COMM event traces

• Clients should be able to acquire a log of all produces, consumes, and COMM Events ("matches") that have occurred in RSpace since the last call to getCheckpoint.
• Given a log of COMM Events, we need to be able to run RSpace in  a "rigged mode" where a new produce or consume that matches the one in the log will cause RSpace to return the same result

Metric for tracking success
