Offline-First Applications with Flutter
Implementing an offline-first application with Flutter as the front-end and Rust as the backend requires a thoughtful approach to data synchronization, caching, and state management. The goal is to enable the app to function effectively without an internet connection, using local storage, and then synchronize any changes with the server once the connection is restored.- Published on
Signature on Web3 - ECDSA Algorithm
Instead of verifying credentials that can be stolen or hacked, we verify network member integrity through cryptographic signatures. The private keys central to these transactions are never exchanged; they are used to encrypt transactions whose signatures confirm identities and maintain trust within the network. At the heart of this new wave is secp256k1, an elliptic curve used in Bitcoin cryptographic functions that is setting the stage for secure and decentralized applications.- Published on
