+Note that we will be using Polkadot binaries and dependencies, as indicative later, but we will be provisioning and locally running our own relay chain.  We will also create and run our own parachain, which will connect to our relay chain.

 - A subset of paravalidators are selected on the relay chain to validate a particular parachain.
 - The parachain's collator passes the block, considered a "Candidate" to the relay chain.
 - The collator also passes the PVF, or **parachain validation function**, to the paravalidators.  The PVF validates that the transitions in the candidate block is valid.
-- A candidate block gets **backed** by the paravalidators.
+- A candidate block gets **backed** by the paravalidators, and contains a **Proof of Validity**, or **PoV**.
 - The validators on the relay chain, after a second series of checks, include the block.

+- A Parachain Validation Function, or **PVF**, is essentially the Wasm runtime of a parachain.  It defines how state is supposed to transition for that certain parachain.
+- The proof of validity is generated once the state is able to be verified.  The entire state of the parachain doesn't need to be verified - just the proposed state changes for that particular parablock.
+
+In the section page, we also discussed Cumulus, a Parachain Development Kit based on FRAME and Substrate.  Cumulus provides the functions needed for collators to provide the PVF and information for the proof of validity to be generated, which is required for the parachain to finalize its state on the relay chain.
