Tendermint is a Byzantine fault tolerant consensus engine that replicates a deterministic state machine across a cluster of machines while tolerating up to one-third malicious validators. It functions as a blockchain application platform, connecting application logic to the consensus engine through a socket-based protocol that enables development in any programming language. The system commits blocks when more than two-thirds of weighted validators sign and broadcast their votes, with proof included in the next block. It provides cryptographic state verification, allowing efficient authentica

Blitzar एक वेरिफिएबल SQL प्रूफ इंजन और क्रिप्टोग्राफिक लाइब्रेरी है जिसे वेरिफिएबल SQL कंप्यूटेशन के लिए डिज़ाइन किया गया है। यह ऑन-चेन सत्यापन के लिए परिणामों की शुद्धता को प्रमाणित करने वाले ज़ीरो-नॉलेज प्रूफ जेनरेट करते समय डेटाबेस क्वेरी को ऑफ-चेन निष्पादित करने में सक्षम बनाता है। यह प्रोजेक्ट एक GPU-त्वरित प्रूफ एक्सीलरेटर के माध्यम से खुद को अलग करता है जो भारी क्रिप्टोग्राफिक वर्कलोड को ग्राफिक्स प्रोसेसर पर ऑफलोड करता है, जिससे संक्षिप्त प्रूफ जनरेशन के लिए आवश्यक समय कम हो जाता है। यह C++ और Rust एप्लिकेशन के लिए उच्च-प्रदर्शन क्रिप्टोग्राफिक प्रिमिटिव प्रदान करता है, जो एलिप्टिक कर्व ऑपरेशंस और मल्टी-स्केलर मल्टीप्लिकेशन पर केंद्रित है। यह सिस्टम डेटा प्रबंधन और सुरक्षा की एक विस्तृत सतह को कवर करता है, जिसमें ट्रस्टलेस डेटा एकीकरण शामिल है जो ब्लॉकचेन इंडेक्सिंग को ऑफ-चेन डेटासेट के साथ छेड़छाड़-रोधी रिलेशनल टेबल में जोड़ता है। यह स्टेट अखंडता बनाए रखने के लिए BFT कंसेंसस और थ्रेशोल्ड सिग्नेचर का उपयोग करता है, साथ ही स्मार्ट कॉन्ट्रैक्ट कॉलबैक के माध्यम से कोरम-आधारित डेटा सिंक्रोनाइज़ेशन और सत्यापित परिणाम वितरण के लिए तंत्र का उपयोग करता है। कोडबेस अपने क्रिप्टोग्राफिक टूलसेट्स और प्रूफ कंप्यूटेशन लाइब्रेरी को उजागर करने के लिए C++ और Rust के लिए नेटिव बाइंडिंग प्रदान करता है।

Zeebe is a cloud-native workflow engine and distributed state machine designed for business process orchestration using BPMN and DMN standards. It operates as a high-performance gRPC workflow runtime that executes complex business processes through a partitioned event-streaming architecture. The system also functions as an orchestrator for large language model agents, coordinating AI reasoning and tool use within deterministic business processes. The engine is distinguished by its peer-to-peer broker networking and a consensus-based data replication model that ensures high availability and fa

braft is an embeddable C++ library that implements the Raft consensus algorithm, providing a distributed consensus engine for building fault-tolerant, replicated state machines. At its core, it manages leader election, log replication, cluster membership changes, and state machine synchronization across a cluster of nodes, ensuring strong consistency and data durability even in the face of node failures. The library distinguishes itself through a comprehensive set of mechanisms for reliable distributed coordination. It uses a randomized timeout-based leader election process with term manageme

sofa-jraft is a Java implementation of the Raft consensus algorithm. It serves as a distributed consensus engine and linearizable state machine designed to ensure high availability and data consistency across a cluster of nodes. The project provides a replicated key-value store and a coordination engine for managing distributed state. It distinguishes itself through support for multi-group consensus sharding to distribute traffic and a service provider interface that allows for custom log storage and entry encoding implementations. The system covers a wide range of distributed capabilities,

Olric is a distributed data grid and in-memory key-value store that partitions and replicates data across a cluster of servers. It serves as a shared memory system for managing distributed maps, performing atomic operations, and acting as an in-memory data cache. The system provides a distributed locking mechanism for concurrency control and a pub-sub messaging system that broadcasts and routes messages over named channels across the cluster. The platform covers wide-ranging capabilities including cluster management and orchestration, data replication with configurable quorums, and automated

Stellar Core is the primary software implementation of the Stellar blockchain network, serving as a distributed ledger and a Federated Byzantine Agreement system. It functions as a core node that maintains the shared state of the network and provides a runtime environment for executing WebAssembly smart contracts. The project enables the creation and management of digital assets, including the implementation of decentralized exchanges through distributed orderbooks and automated liquidity pools. It facilitates cross-border payment settlement by routing assets via path payments and bridging di
