Hub Transaction Bundle (HTB)
What does Hub Transaction Bundle (HTB) mean?
A bundle signed by the hub and sent to each validating node, that contains all the candidate transactions under consideration for a given block.
After an end user contacts an honest node in the Active Node List (ANL) for its blockchain, all valid transactions should end up in an honest blockchain.
Geeq’s Proof of Honesty protocol is structured to provide each validating node the same set of inputs. If each node is honest and follows the same strict set of rules, every honest node will reach the same conclusion about which transactions are validated, written into a block, and used to update the node’s Current Ledger State.
The Hub Transaction Bundle*
The Hub Transaction Bundle (HTB) is an innovation by Geeq to track whether the same set of candidate transactions are delivered to each validating node or not. Candidate transactions are called Unverified User Transactions (UUTs). UUTs are bundled into their own Node Transaction Bundles (NTBs) and signed, delivered to the hub who bundles all the NTBs (including its own) into a HTB and signs it, and then sends the signed HTB back to each node.
Once each node receives the HTB, they independently make decisions to validate the UUTs in the HTB. When an honest hub sends each node the same HTB, all honest nodes who follow protocol independently arrive at the same, correct, current view.
Safeguards for Dishonest Hubs.
Unlike other blockchain protocols, Geeq makes no security assumptions about the honesty of any node because the reality is there are honest and dishonest actors in the world in some unknown proportion. As a result, Geeq’s protocol builds in the ability to detect honesty for every node’s work. If a hub is dishonest, the rest of the nodes will discover its dishonest HTB. Dishonest hubs are audited out of the Active Node List, lose their Good Behavior Bonds, and another node assumes the role of the hub.
The workflow is very detailed and part of Geeq’s proprietary protocol. All code will be open source when Geeq releases its main net.
A Hub is a Node with More Work, Not More Power.
Some blockchain protocols endow a node or nodes with more power than others which introduces attack vectors. As a simple example, a known block proposer may be pressured or corrupted. Proof of Honesty’s workflow deliberately separates, isolates, and tracks communication tasks so no node has more power than another.
Used in a Sentence:
Geeq’s hub has the task of signing a Hub Transaction Bundle (HTB) to ensure each node receives the same, neutrally determined, set of inputs.
*This is a simplified, conceptually accurate description of the workflow logic.
