Sway is a smart contract development language and programming environment designed for writing, compiling, and deploying secure blockchain programs. It serves as a type-safe language for building on-chain logic and a static analysis toolchain that validates contracts before they are executed on a network. The ecosystem provides a development environment focused on blockchain application logic and web3 backend engineering. It integrates a type-safe programming approach to reduce vulnerabilities and ensure reliable state transitions for decentralized services. The toolchain incorporates static

This project is a curated directory and index of resources for Solidity smart contract development. It provides a categorized collection of libraries, development frameworks, security tools, and educational materials used to build and deploy decentralized applications. The repository functions as a comprehensive catalog for the software development lifecycle, featuring a specific index of community-vetted modular building blocks and token standard implementations. It also maintains a dedicated list of security resources, including static analyzers and fuzzers, to assist in auditing and securi

This is an educational resource that provides a comprehensive guide to blockchain and distributed ledger technologies, covering everything from fundamental concepts to practical deployment. The guide systematically explains the core architecture of blockchain systems, including consensus-based distributed ledgers, cryptographic hash chains, Merkle trees, and smart contract execution engines, while also detailing permissioned channel architectures and modular service platforms for enterprise use. The resource distinguishes itself by offering a dual-track learning path that serves both non-tech

NETCoreSync is a database synchronization framework where each client's local offline database (on each client's multiple devices) can be synchronized on-demand via network into a single centralized database hosted on a server. Data which are stored locally within each device of a single client…

fish-redux is a Flutter application framework and state management library that implements a Redux-based workflow. It provides a centralized state container and uses reducers and actions to maintain a single source of truth, ensuring data consistency across application screens and components. The framework includes a state-to-UI connector that transforms raw state data for display and automatically updates views. It features a component lifecycle manager that triggers logic and state updates based on when UI components mount or unmount. The project covers dependency injection for reducing co

A High-Level Abstraction Framework for Quantum Algorithms

Ethereum blockchain orchestration, testing, CLI, and Dapp scaffolding.

Scaffold-eth is a comprehensive development stack and boilerplate for building decentralized applications. It provides a pre-configured starter kit that integrates smart contract development tools with a reactive user interface to accelerate the construction of Ethereum-based projects. The toolkit features dynamic frontend interface generation, which automatically builds a user interface mapped to smart contract functions for rapid logic verification. This allows for testing blockchain logic through a frontend without the need to write custom UI code. The project covers a broad range of deve

A graceful isomorphic framework build top of Next.js and Egg.js

Aya is a Rust-native framework for writing, compiling, and loading eBPF programs into the Linux kernel. It provides a complete development environment that eliminates the need for a C toolchain or libbpf, allowing developers to work entirely within the Rust ecosystem. The framework manages the full lifecycle of eBPF programs, including async runtime integration, CO-RE BTF resolution for kernel version portability, ELF-based program loading, and safe kernel memory access. The framework distinguishes itself through its pure Rust compilation pipeline, which compiles Rust source code directly int
