    Union

    Union

    Serverless backend platform for Web3-native app development

    ...It provides a serverless execution layer with built-in authentication, event handling, and state management tailored for decentralized systems. Developers can write backend logic using WebAssembly and deploy logic that interacts with smart contracts and blockchain data without managing infrastructure.

    Libplanet

    Libplanet

    Blockchain in C#/.NET for on-chain, decentralized gaming

    Libplanet is a .NET library for creating multiplayer online game in decentralized fashion, which means the whole gameplay occurs on a peer-to-peer network among equal nodes rather than an authorized central server. Under the hood, it incorporates many features (e.g., digital signature, BFT consensus, data replication) of a blockchain.

    Plutus

    Plutus

    The Plutus language implementation and tools

    Plutus is the smart contract development framework for the Cardano blockchain, created using Haskell. It provides the core infrastructure for writing, testing, and deploying secure, deterministic smart contracts on the Cardano platform. Plutus includes a custom functional language (Plutus Core), a higher-level embedded DSL (Plutus Tx) for writing contracts in Haskell, and an off-chain infrastructure for managing interactions. It ensures strong correctness guarantees through formal...

    Linera Protocol

    Linera Protocol

    Main repository for the Linera protocol

    ...Each domain (shard) handles its own commands and state transparently; inter-domain operations rely on well-defined messaging layers and proofs to preserve consistency without central coordination. The protocol supports dynamic reconfiguration: shards can split, merge, or reassign workloads while preserving correctness. By decoupling domain logic from global consensus, Linera can support modular upgrades, domain-specific smart contracts, and high throughput across partitions.

    Jesse

    Jesse

    An advanced crypto trading bot written in Python

    Jesse is an open-source AI agent framework designed to help developers build and orchestrate intelligent workflows that combine large language models (LLMs) with external tools, automation logic, and real-world actions. It acts as an agent manager where you can define tasks, contexts, and tool integrations so that AI reasoning is reliably connected to deterministic procedures like API calls, data retrieval, and task execution. Jesse emphasizes structured outputs, safety boundaries, and explainable reasoning, helping users design agents that don’t just hallucinate responses but can coordinate steps, validate conditions, and interact with systems predictably. ...

    Decred

    Decred

    Decred daemon in Go (golang)

    dcrd is the full-node implementation of Decred, a hybrid proof-of-work/proof-of-stake cryptocurrency focused on decentralized governance, long-term sustainability, and robust network security. Written in Go, dcrd provides all the core consensus, networking, and validation logic necessary for Decred nodes to participate in the network. It plays a critical role in enforcing consensus rules, managing peer connections, and enabling advanced features like on-chain voting and self-funding via a decentralized treasury. Designed to prioritize stability and security, dcrd is suitable for miners, validators, and users operating infrastructure for the Decred blockchain.

    Rust-Lightning

    Rust-Lightning

    Bitcoin Lightning library written in Rust

    Rust-Lightning is a Bitcoin Lightning library written in Rust. The main crate, lightning, does not handle networking, persistence, or any other I/O. Thus, it is runtime-agnostic, but users must implement basic networking logic, chain interactions, and disk storage. The project implements all of the BOLT specifications in the 1.0 spec. The implementation has pretty good test coverage that is expected to continue to improve. It is also anticipated that as developers begin using the API, the lessons from that will result in changes to the API, so any developer using this API at this stage should be prepared to embrace that. ...

    web4

    Web4 is a new way to distribute decentralized apps

    ...Deploy a single WASM smart contract to deploy the whole web app. You only need to deploy a single smart contract using WebAssembly to host your app's HTTP backend, static resources, and blockchain logic. There is an HTTP gateway to NEAR blockchain which allows smart contract to handle arbitrary GET requests. Every smart contract on NEAR also gets a corresponding API endpoint which can be accessed through regular HTTP requests. You can load any required data in web4_get by returning list of URLs to preload in preloadUrls field. Note that both JSON and form data are supported. ...

    Blankly

    Blankly

    Easily build, backtest and deploy your algo in just a few lines

    ...We built blankly for every type of quant including training & running ML models in the same environment, cross-exchange/cross-symbol arbitrage, and even long/short positions on stocks (all with built-in WebSockets). Blankly is the first framework to enable developers to backtest, paper trade, and go live across exchanges without modifying a single line of trading logic on stocks, crypto, and forex. Every model needs to figure out how to buy and sell. We make it super easy for you so you can focus on building better trading algos. Your models can run on any platform, and on any supported exchange. We make that as easy as just changing one line of code.
