5 · Utility Value of PAD

hashtag
Key user benefits

  • Instant savings – PAD-linked discounts of roughly 5–20 % on eligible services make everyday usage more cost-effective than most comparable alternatives.

  • Dynamic vouchers – staking accrues time-bound service credits (e.g., access hours, upgrade coupons, dining perks); unclaimed credits expire if the stake is closed prematurely.

  • Token payments – PAD can be spent in the in-app marketplace for custom NFTs and, in future, for additional modules such as accommodation bookings.

5 · Technical overview

5.1 Three-layer logical model

Layer
Purpose
Illustrative details

UX / PWA

Zero-install client, offline caching, push alerts and deep-links (e.g., dapp://paddr.io/stake).

≈ 85 % static assets cached for fast reload speeds.

Service layer

Loyalty-Engine micro-services handle staking maths, voucher issuance and snapshot writing.

Horizontally scalable cluster; message queue ensures > 99 % availability.

On-chain core

Immutable staking, NFT mint/burn, PAD token logic and treasury movements.

Cron functions executed via decentralised keepers on an EVM-compatible network.

5.2 Data flow (high-level)

5.3 Fault-tolerance measures

  • Graceful degradation – if the off-chain Engine is unavailable, users can still interact directly with smart-contracts to unstake or query balances.

  • Circuit-breaker – an automated monitor pauses new staking when abnormal gas prices or network anomalies are detected; manual review is required to resume operations.
