Presentation of PoD Theory at ISADS, Achieving Both Onboarding of Large Numbers of Users and Low Power Consumption

We are pleased to announce that the paper on Xenea’s proprietary consensus algorithm, Proof of Democracy (PoD), titled “Enhance the Mining Popularity with Low Power Consumption on PoA Autonomous Decentralized Voting Blockchain,” has passed peer review and was presented at the 2025 IEEE 16th International Symposium on Autonomous Decentralized Systems (ISADS) held in July 2025.

The paper was presented in ISADS’s “ONLINE Session 1: AI, Blockchain, and Security.” In the paper, the Xenea blockchain is treated as a Voting Blockchain, extending a Proof-of-Authority (PoA) blockchain that does not require vast amounts of energy for consensus. It introduces the Rep Node, which enables onboarding of large numbers of users while achieving low power consumption and low latency.

Rep Nodes play a central role in the practical implementation of the Xenea blockchain within the PoD framework, serving to perform transaction authenticity verification on behalf of users.

Introduction

Title:

Enhance the Mining Popularity with Low Power Consumption on PoA Autonomous Decentralized Voting Blockchain

Overview:

Blockchain is one of autonomous decentralized system which is using the policy of connected ledger to generate the transaction proof by the all of participant node certification. To do this, it is required the massive number of participating users to maintain its Blockchain generation task by its mining process. There are some types of blockchain mining. PoA type Blockchain mining doesn't require strong computation power in each node due to selected node mining policy. The stability of Blockchain generation task is defined by the mining node popularity, availability and low latency time node response with less electricity power consumption. Therefore, PoA Blockchain mining required massive number of nodes. It also needs low electric power consumption manner. This paper proposes REP node for mobile user mining on PoA blockchain system. Proposing REP node can manage up to 100,000 mobile users mining tasks with low latency time mining manner with low electric power consumption. Connecting mobile user can receive the mining reward from REP node by the effort of PoA participation of mining. This paper shows REP node system design, its implementation and node availability / low power consumption evaluations. REP node solution will be a one solution to break Decentralized trilemma challenge in the future.
