The platform manages transactions through a simplified UTXO model that minimizes on-chain state and supports fast validation. The project introduces Chialisp, a Turing-complete functional smart contract language designed for secure and auditable financial transactions. It features a pooling p

Monero is a privacy-focused cryptocurrency and proof-of-work blockchain designed for private digital payments. It utilizes a peer-to-peer network and a distributed ledger to allow users to send and receive currency while hiding transaction senders, receivers, and amounts. The system achieves financial confidentiality through the use of ring signatures for sender obfuscation and RingCT with Bulletproofs to hide transaction values. To ensure network security and decentralization, it employs a memory-hard proof-of-work algorithm optimized for general-purpose CPUs. The project provides a full no

Hardhat is a smart contract development framework and EVM tooling suite designed for the full lifecycle of Ethereum and EVM-compatible applications. It serves as a development environment for compiling, testing, and deploying smart contracts, providing a local blockchain simulation and a programmable task runner. The framework is distinguished by its extensive simulation capabilities, including the ability to fork remote network state and manipulate block time or account balances. It features a hook-based plugin system that allows for the extension of core functionality and the creation of cu

This project is a Python implementation of a distributed ledger system. It serves as a blockchain prototype designed to demonstrate the creation and linking of data blocks in a sequential chain. The system utilizes a proof-of-work consensus mechanism and a hash-linked block sequence to maintain data integrity. It includes a REST API that allows external clients to query the ledger state and submit transactions over HTTP. The implementation covers core distributed ledger capabilities, including sequential block chaining and in-memory state management.

This is an ECMAScript proposal that introduces a pipeline operator for JavaScript, enabling left-to-right expression chaining with a dedicated placeholder token to reference the previous step's value. The proposal defines a syntax-only transformation that desugars to standard JavaScript, requiring no new runtime support or engine primitives. The pipeline operator allows chaining operations sequentially, passing each result to the next step in natural reading order. It includes a null-safe variant that short-circuits on nullish values, returning them unchanged and skipping remaining steps. Eac

Este proyecto es un simulador y visualizador educativo interactivo de blockchain. Sirve como herramienta para demostrar cómo se minan y encadenan los bloques mediante hashing criptográfico y prueba de trabajo (proof of work). La aplicación se centra en la simulación de un registro distribuido, permitiendo a los usuarios visualizar la estructura interna de un registro inmutable. Demuestra específicamente el proceso de minería de bloques, donde se debe encontrar un nonce válido para cumplir con un umbral de dificultad de minería ajustable. El sistema cubre la visualización de operaciones de registro, encadenamiento de bloques criptográficos y actualizaciones de hash en tiempo real para ilustrar la integridad de los datos. Toda la aplicación se proporciona como una aplicación web dockerizada para asegurar un despliegue consistente en diferentes entornos de alojamiento.

Grin es una implementación de protocolo y nodo de blockchain que proporciona un sistema de transacciones confidenciales. Utiliza compromisos de Pedersen (Pedersen Commitments) y cifrado homomórfico para verificar la integridad del valor y garantizar un suministro monetario consistente sin revelar montos de transacción específicos o identidades de los participantes. El proyecto se distingue por un modelo de intercambio de transacciones interactivo, donde las billeteras coordinan intercambios de datos de múltiples rondas para construir transacciones firmadas. Para mantener el anonimato, el sistema admite la entrega de transacciones mediante enrutamiento cebolla (onion-routing) y enmascara las direcciones IP de origen a través de mecanismos de retransmisión especializados. También incorpora prueba de trabajo (proof-of-work) resistente a memoria para resistir el dominio de la minería ASIC y utiliza un modelo de libro mayor de poda de estado con almacenamiento Merkle Mountain Range para reducir la huella de disco de la blockchain. El código base cubre un amplio conjunto de capacidades, incluyendo la ejecución de intercambios atómicos cross-chain sin confianza, la gestión de billeteras deterministas jerárquicas y la operación de nodos de red completos. Proporciona herramientas para minería limitada por memoria, ejecución de contratos criptográficos mediante timelocks y comunicación segura cliente-servidor utilizando cifrado autenticado. El nodo puede desplegarse como una imagen de contenedor con soporte para persistir datos de caché.

Lists is a curated collection of DNS blocklists, a domain blocklist generator, and a categorized library of domains used for network content filtering. The project provides a command-line pipeline that aggregates upstream sources to build and validate blocklists used to redirect unwanted traffic to null addresses. The project distinguishes itself through a CLI-driven build pipeline that automates the fetching, validation, and daily regeneration of datasets. It organizes domains into discrete functional categories rather than a single monolithic list and exports them in multiple syntaxes, incl
