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 is a verifiable SQL proof engine and cryptographic library designed for verifiable SQL computation. It enables the execution of database queries off-chain while generating zero-knowledge proofs that certify the correctness of the results for on-chain verification. The project distinguishes itself through a GPU-accelerated proof accelerator that offloads heavy cryptographic workloads to graphics processors, reducing the time required for succinct proof generation. It provides high-performance cryptographic primitives for C++ and Rust applications, focusing on elliptic curve operations

Zeebe هو محرك سير عمل سحابي أصلي وآلة حالة موزعة مصممة لتنسيق العمليات التجارية باستخدام معايير BPMN وDMN. يعمل كمحرك سير عمل gRPC عالي الأداء ينفذ عمليات تجارية معقدة من خلال بنية تدفق أحداث مجزأة. يعمل النظام أيضاً كمنسق لوكلاء النماذج اللغوية الكبيرة، حيث ينسق تفكير الذكاء الاصطناعي واستخدام الأدوات ضمن العمليات التجارية الحتمية. يتميز المحرك بشبكة وسيطة من نظير إلى نظير ونموذج تكرار بيانات قائم على الإجماع يضمن التوافر العالي وتحمل الأخطاء. يستخدم مجموعة وسطاء مجزأة لتحقيق قابلية التوسع الأفقي ويستخدم ضغطاً عكسياً للطلب التكيفي لتنظيم تدفق الأوامر الوارد ومنع التحميل الزائد للنظام. تغطي المنصة سطحاً واسعاً من الإمكانيات التشغيلية، بما في ذلك مراقبة التنفيذ في الوقت الفعلي مع خرائط حرارة الأداء، واتخاذ القرارات التجارية المؤتمتة عبر جداول القرار، وتنفيذ المهام الموزعة من خلال نموذج عامل مهمة يعتمد على الاقتراع. كما يوفر أدوات لعزل موارد المستأجرين المتعددين، والتحكم في الوصول القائم على الهوية، وتكامل واجهات برمجة تطبيقات الويب الخارجية والدوال بدون خادم. يمكن نشر النظام عبر بيئات مختلفة، بما في ذلك Kubernetes وDocker، ويتم إدارته من خلال مزيج من واجهة سطر الأوامر وواجهة برمجة تطبيقات REST برمجية.

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
