Block and Node Parameters

Node Design and Role Distribution PopChain adopts a DPoS (Delegated Proof of Stake) consensus mechanism, combined with the modular Cosmos SDK architecture. The network consists of three types of nodes:

Validator Node Responsible for block production and maintaining consensus; must stake PPT tokens and accept delegated voting rights.

Delegator Node Regular token holders can delegate their voting power to validators and share in the rewards.

Light Node Used primarily for data verification and fast synchronization; low operational cost, suitable for regular users.

Parameter	Configuration
Consensus Mechanism	DPoS (Delegated Proof of Stake)
Block Time	3 seconds (supports high-frequency social interactions)
Block Size	Dynamically adjustable, initially 2MB
Final Confirmation	Approximately 2 blocks (<10 seconds)
Node Reward Method	Block rewards + transaction fees + behavior-based incentives

Node Incentives

Reward Rules:

• Block rewards are distributed to validators and their delegators.

• Validators earn a share of transaction fees (including gas and cross-chain bridge service fees).

• Incentives are tied to behavior data—validators must maintain high uptime and service quality.

Governance Requirements:

• Minimum Stake: Validators must stake a minimum amount of ecosystem tokens to participate in consensus.

• Governance Duty: Validators are required to participate in governance voting. Inactivity results in partial slashing of staked tokens.

• Behavior Score Impact: Validators must maintain ≥95% uptime. Failure to meet the threshold reduces block rewards.

Cross-Chain Nodes and IBC Integration

• PopChain validators must support IBC (Inter-Blockchain Communication) channels to ensure interoperability with Cosmos Hub, Osmosis, Ethereum, and other networks.

• A cross-chain relay node system is planned to incentivize liquidity bridging across the ecosystem.
