Node Block Triple

What does Node Block Triple mean?

A node block triple (NBT) is a message unique to the Geeq protocol that efficiently organizes what it submits for validation as well as the information required for proof(s).

Each active node_i in the network for a Geeq chain must sign and send its own Node Block Triple (NBT) to the to the node acting as the hub for block B. This action is also required of the node acting as the hub.

Required Elements of the Node Block Triple

Node Content Statement (NCS_i):
The NCS_i includes node_i’s chain state view at block height (B-1) and the merkle roots of the two lists (the NTL_i and NPL_i) it is submitting for consideration for block B. The node is held accountable for its chain state view and the merkle roots by signing its NCS_i with its private key.

Node Transaction List (NTL_i):

The NTL_i includes the count of UUTs in its list and its list of sane UUTs. These UUTs may or may not carry a data payload, depending on its transaction type. An Unverified Validation Transaction (UVT) does not carry a data payload. An Unverified Application Transaction (UAT) does.

Node Payload List (NPL_i):
The NPL_i includes the count of payloads and its list of payloads that are hash referenced in the Unverified Application Transactions (UATs) it has received.

Main Idea

Each individual node is held accountable for its work to follow Geeq’s validation protocol and build its own chain. In doing so, a user who contacts a node may expect an honest node to provide proof it has followed protocol, the blockchain has not been corrupted, and therefore the information is safe to use.

The Node Block Triple (NBT) must be signed by the individual node’s private key. The NBT contains the node’s chain state view, which provides the elements for Geeq’s chain hash proof (the ability to prove that node’s blockchain traces back to the genesis block). The NBT separates data for transactions that must be validated at the account level from the data payloads referenced in any transaction using an application.

Used in a Sentence:

The Node Block Triple contains information for the block header, transaction list, and application payloads, organized as separate elements, which contribute to the ability and efficiency to conform to a standard validation process as well as the standard construction of proofs so even a non-technical user can “verify, not trust“.
