Proposal of a Token-Based Node Selection Mechanism for Node Distribution of Mobility IoT Blockchain Nodes

Area of Science:

• Mobility Services
• Blockchain Technology
• Internet of Things (IoT)

Background:

• The proliferation of shared mobility services, driven by IoT advancements and evolving business models, necessitates reliable data aggregation.
• Current public blockchain systems face performance challenges due to intensive mining processes for state updates.

Purpose of the Study:

• To propose a novel mechanism for enhancing data reliability in next-generation mobility services.
• To alleviate the high-performance demands of public blockchains for mobility data management.

Main Methods:

• Implemented a token-based block creation authority system, replacing traditional mining.
• Granted block creation rights to nodes possessing tokens, with tokens dynamically updated and redistributed.
• Ensured token integrity through continuous updates within each block.

Main Results:

• Successfully eased the mining process for state updates in public blockchains.
• Enabled block creation by a select group of token-holding participants.
• Prevented resource-centered centralization by managing token distribution.

Conclusions:

• The token-based mechanism effectively addresses the performance bottlenecks of public blockchains in shared mobility contexts.
• This system enhances data reliability and promotes a more decentralized network structure.
• The approach facilitates the secure and efficient management of data for next-generation mobility services.
