Decentralwatch

DecentralWatch is a decentralized uptime monitoring platform where validators around the world check website availability and earn rewards for contributing real-time, verifiable data. built with bolt.

Inspiration

Monitoring the uptime of critical infrastructure shouldn't rely on centralized services that can fail, censor, or go dark. Inspired by the principles of decentralization, we built DecentralWatch - a DePIN-powered platform where global validators report website uptime and get rewarded on-chain.

What it does

DecentralWatch allows users to track the real-time uptime of websites through a network of decentralized validators - both human-operated and cloud-based. Validators check website health, sign results with Solana keypairs, and submit them to a backend API. The data is aggregated into a clean dashboard with status graphs, history, and reward tracking.

How we built it

  • Frontend: Next.js, TypeScript, TailwindCSS
  • Desktop App: Electron app with Wallet auth
  • Backend: Node.js + Express with PostgreSQL
  • Blockchain: Solana (Web3.js) for validator rewards and validation proofs
  • Cloud Infra: AWS EC2 instances for distributed cloud validators

Challenges we ran into

  • Securely storing validator keypairs in Electron apps
  • Handling unreliable network conditions for human validators
  • Balancing reward distribution with validator cost-efficiency
  • Managing multiple EC2 instances and automating their health checks
  • Designing an intuitive yet developer-grade dashboard UX

Accomplishments that we're proud of

  • Built a working MVP with both cloud and human validator support
  • Onboarded real users to validate websites from different geographies
  • Seamless Phantom integration in user facing and validator explorer website
  • Stored wallet keypair locally at OS level in an Electron environment
  • Deployed globally-distributed cloud validators with regional accuracy
  • Got early grants from Solana × CoinDCX and feedback from Upstox engineer

What we learned

  • Building DePIN systems requires a strong incentive model and UX clarity
  • Electron requires secure key management strategies
  • You can make validators efficient and privacy-preserving
  • Community validators boost credibility, but need thoughtful onboarding

What's next for DecentralWatch

  • Launching on Solana Mainnet
  • Introducing validator reputation scores and staking
  • Adding multi-chain support (Polygon & Ethereum next)
  • Mobile app for validators and website owners
  • DAO-based governance for future roadmap votes
  • Monetization via premium monitoring tools and SLA guarantees
