Building Full-Stack, Secure, and Scalable Applications Without the Infrastructure Headache
summary
Builds a full-stack app on the Internet Computer using Internet Identity passkeys for privacy-preserving login, Rust back end and JS front end deployed as canisters, and 34-node threshold signatures to create noncustodial per-user keys that sign multi‑chain transactions. Canisters act as stateful serverless buckets so no external DB, S3, or auth layer is required; frontends and data are certified on-chain for tamperproof delivery. Demo shows DFX CLI deploying a working canister to mainnet in minutes; ecosystem includes OpenChat and O wallet.
