Proof-of-Retrievability & Slashing FAQs
Get clear answers on our approach to building secure, economically robust decentralized storage and validator networks.
A standard Proof-of-Retrievability (PoR) and slashing mechanism deployment takes 3-6 weeks from kickoff to mainnet audit. This includes design, smart contract development, integration testing, and a final security review. Complex multi-chain or custom consensus integrations can extend to 8-10 weeks. We provide a detailed project plan with weekly milestones at the start.
