Technical Questions on AppChain Data Marketplaces
Common technical and operational questions from CTOs and founders evaluating a custom data marketplace build.
A standard AppChain data marketplace MVP with core features (data listing, tokenized access, basic staking) typically deploys in 6-8 weeks. Full-featured production deployments with advanced monetization models, multi-chain bridges, and custom oracles take 12-16 weeks. We follow a phased delivery model with bi-weekly sprints and demos.
