60+ Enterprise Markets to Be Disrupted by #Kaspa Tech #33 Food Delivery Apps Food delivery apps connect customers, restaurants and couriers, but the platform sits in the middle of almost every part of the transaction. It receives the order, handles payment, tracks delivery, calculates fees, pays restaurants and couriers, manages disputes and keeps the transaction history. Legacy Platforms & Systems • DoorDash, Uber Eats, Skip and Deliveroo • Centralized restaurant and courier marketplaces • Credit and debit card payment networks • GPS and mapping APIs • Restaurant POS integrations • Proprietary courier matching and dispatch • Platform-controlled ratings and reputation • Scheduled restaurant and courier payouts These platforms provide useful services including discovery, logistics and support. There is still plenty of room to rethink how the order, payment and settlement underneath those services work. What’s Broken / Innovation Gaps ❌ Restaurants and couriers depend on a central platform for settlement ❌ Customer payment, restaurant payment and courier payment are separate processes ❌ Payments can settle long after the food is delivered ❌ Order status and disputes depend on platform-controlled records ❌ Refunds and cancellations require the platform to determine where the money goes ❌ Ratings and work history are trapped inside individual apps ❌ Restaurants have limited control over marketplace customer relationships ❌ More automated commerce will require programmable payment and settlement Where Food Delivery Can Still Innovate and Where Kaspa Tech Could Help ❌ The platform controls the money from checkout to payout ✅ Payment could be locked at checkout with the conditions for spending it established from the beginning. Kaspa Covenants can enforce how a UTXO may be spent and validate its next state. Covenant IDs provide continuity as that state changes. An order could move through accepted, prepared, picked up, delivered, cancelled or refunded states while retaining a verifiable lineage. ❌ Developers have to build that logic close to Kaspa Script ✅ SilverScript now provides a higher-level way to write it. SilverScript v1.0.0 is officially released and compiles to Kaspa Script. Developers can define state and transition policies while the compiler handles much of the lower-level Covenant plumbing, state validation and transaction structure. For a delivery application, that could mean writing rules for when funds remain locked, when an order can advance, which outputs are valid and what conditions allow settlement or refund. ❌ One customer payment eventually has to become several payments ✅ The transaction itself can enforce the agreed outputs. Kaspa’s transaction introspection allows a Covenant to inspect and validate transaction outputs. A delivery contract could require the correct amounts and destinations before allowing locked funds to move. That opens the door to settling the restaurant, courier, taxes and other predefined recipients as part of the completed transaction rather than sending everything through a platform account first. ❌ Delivery confirmation and payment are separate events ✅ Delivery confirmation could become an input to the settlement process. A restaurant scan could verify pickup. A customer QR code, signature or another authenticated action could confirm delivery. The Covenant rules determine what constitutes a valid transition and whether the corresponding payment outputs are allowed. ❌ Restaurants and couriers wait for platform payouts ✅ Settlement could occur as part of the completed order transaction. Once the required conditions are satisfied, Kaspa can settle the valid transaction directly rather than leaving balances inside a platform for later reconciliation. ❌ Cancellations and refunds require someone in the middle to control the funds ✅ Valid refund paths can be written into the contract. A Covenant could allow one transition if an order is cancelled before pickup and another once delivery has been verified. More complicated disputes may still require arbitration or another agreed process. The basic settlement rules do not have to be decided after the fact. ❌ A full delivery marketplace involves more than one contract ✅ This is where Argent becomes interesting. Argent is being developed as an actor-based language and compiler for atomic, multi-contract applications on Kaspa. Argent programs compile to SilverScript and its runtime can construct transactions coordinating multiple actors. A future delivery application could potentially model the customer, restaurant, courier and other participants as separate actors whose contracts participate in one coordinated transaction. Argent is still under active development and needs further auditing and hardening before general production use. ❌ Private customer information should not be exposed publicly ✅ Kaspa’s native ZK verification provides another building block for applications that need to prove something without exposing all of the underlying information. This could eventually be useful for identity, eligibility, delivery or other private verification requirements while keeping unnecessary personal information outside the public transaction history. What could that look like? A customer places an order and the payment is locked according to predefined rules. The restaurant accepts it, the courier verifies pickup, and delivery is confirmed at the door. That final confirmation can trigger a transaction distributing payment to the restaurant, courier, taxes and any other agreed recipients. The delivery app can still handle menus, maps, courier matching, notifications, customer service and logistics. It doesn’t necessarily need to hold the funds and manage settlement between everyone involved. Toccata provides the L1 capabilities. SilverScript gives developers a practical language for writing Covenant logic. Argent is exploring how more complex multi-actor applications can be built above that foundation. Got inspired?
