Questions and answers
What does E-Fulfillment mean?
E-Fulfillment refers to the entire process of handling online orders—from payment and processing to packing, shipping, and delivery (to a home or pickup point).
What makes modern E-Fulfillment different?
Modern systems add blockchain-based validation, real-time tracking, and digital product passports to improve transparency, traceability, and security.
Why use stablecoins in e-fulfillment?
Stablecoins ensure fast, low-fee, and currency-stable transactions. They’re especially useful for cross-border commerce and programmable payment flows.
Can stablecoins generate yield while goods are in transit?
Yes. Funds locked can be allocated to short-term yield strategies, returning interest during delivery time.
What are multiparty locks?
These are smart contract conditions where funds are held until multiple parties agree (e.g., buyer, seller, and courier). No single party can release the funds unilaterally.
Why use multiparty locks in ecommerce delivery?
To prevent disputes. Payment is only released when all agreed-upon criteria are met (e.g., package received and authenticated).
What is a multiparty lock in this setup?
It’s a smart contract where payment is only released when all stakeholders (seller, courier, and buyer) fulfill predefined conditions.
What happens if delivery fails?
The locked funds can be automatically refunded or rerouted based on the smart contract rules—reducing disputes and improving trust.
What role do Provenance Tags play?
They verify the product’s authenticity and origin. NFC or QR tags are linked to a blockchain record, which customers can check instantly.
Can tags detect tampering?
Yes. Tamper-evident tags can trigger an alert if someone tries to remove or replace them before delivery confirmation.
What is a single-tap receipt experience?
It allows a customer to complete confirmation of delivery, authentication, and payment release with one tap on their smartphone—typically via NFC or QR. This replaces traditional signatures or paperwork.
How does it improve the delivery process?
It simplifies proof of receipt, reduces fraud, and provides instant access to product data or brand stories.
What does ‘single-tap’ mean in this context?
It means that the user can confirm receipt, authenticate the product, and release payment by simply tapping their phone on the tag—no app required.
How is ZKP (Zero-Knowledge Proof) used here?
ZKP verifies the recipient’s identity without revealing personal data, ensuring privacy-compliant delivery confirmation.
What role does ZKP play in the single-tap process?
ZKPs verify the recipient’s identity or eligibility without exposing personal information. This ensures privacy while confirming the right person received the package.
Is ZKP secure and compliant with regulations?
Yes, ZKPs are privacy-preserving cryptographic tools used in GDPR-compliant digital ID systems, like Concordium.
What is yield generation in this context?
Funds held in stablecoins during shipping can generate interest (yield) via DeFi protocols. This turns delivery wait time into a productive financial period.
Who benefits from the yield?
It can be shared between seller, buyer, or platform, depending on the agreement. It adds value without increasing transaction fees.
