Olá! This project sounds fantastic – building a robust SensorRegistry and AccessPass system on Substrate is a really interesting challenge. I’ve worked extensively with Substrate development, NFTs, and secure API integrations, and I’m confident I can deliver a well-structured POC. My experience includes developing similar decentralized identity solutions, and I’m eager to apply those skills to this specific use case. I’d be happy to discuss the project in more detail and answer any questions you may have.

✋ Hi there. I can build a Substrate-based sensor registry with Rust exactly as you outlined. ✔️ I have strong experience working with Rust, Substrate, and blockchain. I built a proof-of-concept on Substrate that tracked IoT sensor data on-chain, handling registry, updates, and verification, all with a clean Rust runtime module. ✔️ I will create a Substrate runtime pallet to register sensors, store data, and manage access rights. I’ll write the Rust code, integrate storage maps and events, and connect everything to the Peaq framework. I’ll test on local node and deploy to a testnet to validate, then refine for security and performance. ✔️ After the POC, I’ll share the node and runtime code, offer setup instructions, and help you run tests. I’ll stay available for questions and guides so you can move forward smoothly. Please click the ‘Chat’ button so we can review your exact needs and get started. Best regards, Mykhaylo

I am available to start working on this project immediately and I look forward to collaborating with you to bring this innovative solution to life. Please let me know how you'd like to proceed with the milestones and any specific details you would like to discuss. Thanks, Nikola

@emilesd617

Hi, I am a full-stack AI developer with expertise in TypeScript, Rust, and Node.js. I have experience working with blockchain technologies and am familiar with peaq/Substrate environments. I have developed projects using Rust for pallets/contracts and TypeScript for APIs, JWT, and UIs. For the Peaq/Substrate POC project, I can create the SensorRegistry, AccessPass NFTs, and secure off-chain access using TypeScript for the listener, API, JWT, SDK, and demo UI. I will ensure reorg handling and idempotent processing in the off-chain listener. I have experience with Docker Compose for local development environments. I have worked on similar projects and can provide relevant repositories for review. My approach to handling chain reorgs and idempotency in listeners involves thorough documentation and testing. I will propose a detailed milestone plan and ensure availability aligned with your project requirements. Looking forward to discussing further. Thanks, Emile.

Hi there, As an experienced full stack developer and bug-buster, I bring a unique skill set to your project. Not only can I build the entire tech stack – from Rust pallets and contracts to TypeScript/Node.js listeners, SDKs, and APIs - but I always approach projects with common sense. This means not just creating working code, but anticipating potential issues like reorgs and idempotency, ensuring resilience, and documenting meticulously. One of my recent contributions for Substrate that aligns closely with your project is a blockchain-based digital signature system that allowed secure access to financial documents using Smart Contracts. Apart from that, I have also been heavily involved in several peaq testnet projects deploying on agung/Krest testnets. Timing wise, I'm based in the Philippines which is GMT+8. My band of time overlaps with most global business hours - this means better communication, faster resolution, and less time waiting on replies! Whether you settle for fixed rates or an hourly concept with a weekly cap plus assumptions rest assured that your vision will be translated directly into milestones so we're always on the same page. Let’s team up and make this peaq/Substrate POC shine! Thanks! Daniel
