Release v1.12.0

Apache ResilientDB v1.12.0-incubation (2026-02-04)

Core Improvements

• Securing Consensus Against Long-Range Attacks
  Added a proof-of-concept implementation to secure consensus from long-range attacks through collaborative mechanisms.
  (#215, closes #216)
  — Junchao Chen

• LevelDB-Based Persistent Storage and Faster Recovery
  Introduced LevelDB as a persistent storage backend. ResilientDB now loads state directly from storage and replays only missing logs on startup, significantly reducing recovery time compared to full log replay.
  (#208)
  — Junchao Chen

• Configuration Format Enhancements
  Added support for license headers in existing configuration files to improve compliance and consistency.
  — Junchao Chen

• Certificate and Key Handling Cleanup
  Removed committed .pub / .pri certificate and key files from the source distribution and replaced them with a setup-time script for key and certificate generation.
  (#228)
  — Harish Krishnakumar

Ecosystem Enhancements

• GraphQL Server and Python SDK Compatibility Fixes
  Updated the GraphQL server to support the new configuration format and fixed a GraphQL-related bug in the Python SDK.
  (#228)
  — Harish Krishnakumar

• Automated Deployment via GitHub Actions and Vercel
  Introduced automated CI/CD pipelines for deploying ecosystem tools (ResLens, Beacon, Nexus, etc.) from the monorepo using GitHub Actions and Vercel.
  (#228)
  — Harish Krishnakumar

• Automated Documentation Generation Workflow
  Added a workflow based on Pocketflow to keep documentation continuously updated as the codebase evolves.
  (#229)
  — Bismanpal Anand

• ResLens
  Enhanced CPU and memory profiling with flame graphs and real-time metrics, along with streamlined deployment from the monorepo.
  — Harish Krishnakumar, Bismanpal Anand

• Beacon
  Expanded the documentation platform with AI-generated and human-verified insights derived directly from the ResilientDB codebase.
  — Harish Krishnakumar, Bismanpal Anand

• Nexus
  Improved the RAG-based application for interacting with consensus-related documents, including books, papers, and PBFT research materials.
  — Harish Krishnakumar

• GraphQ-LLM
  Added an MCP server and HTTP API providing an AI-powered query tutor for ResilientDB GraphQL, including explanations, efficiency metrics, and RAG over documentation.
  — Harish Krishnakumar

• ResilientDB MCP
  Introduced an MCP server for direct ResilientDB operations, supporting GraphQL-based blockchain and asset interactions as well as HTTP REST key-value operations via Crow.
  — Harish Krishnakumar

• ResInsight MCP
  An MCP server for exploring the ResilientDB ecosystem. It provides an educational assistant and knowledge-base integration.
  — Kunjal Agrawal

Apache ResilientDB v1.10.0-incubating

Apache ResilientDB v1.10.0-incubation (2024-7-11)

Add the prototype of PoE. (Junchao Chen)

• Implement the base version of the Proof-of-Execution (PoE) Consensus Protocol [EDBT 2011].

Add ResView Data Collection and APIs (Saipranav-Kotamreddy)

• Consensus data such as PBFT messages and states is now collected and stored
• Added APIs to query consensus data and progress of replicas
• Added APIs to trigger faultiness and test view change

NexRes v1.9.0

Support Multi-version Key-Value Interface. (Junchao Chen)

• Get and Set need to provide a version number to fetch the correct version of the data (if exists) or write to the correct version of data (if not overwritten already), respectively.
• Provide interfaces to obtain historical data with a specific version or a range of versions.

NexRes v1.8.0

The view-change recovery protocol was extensively expanded to support the following Byzantine failures through primary/leader replacement and replica recovery. (Dakai Kang)

• Byzantine primary becomes non-responsive, stopping proposing any new Pre-Prepare messages.
• Byzantine primary equivocates, proposing two different client requests to two subsets of replicas.
• Byzantine replicas try to keep some non-faulty replicas in the dark.
• Byzantine new primary becomes non-responsive, refusing to broadcast New-View messages.

NexRes v1.7.0

For each replica local recovery from durable storage upon system restart was added.

NexRes v1.6.0

Refactoring and enhancement of the codebase to highlight the entire software stack of ResilientDB consisting of the following layers

• SDK Layer (C++, Python, Go, Solidity)
• Interface Layer (key-value, smart contract, UTXO)
• ResilientDB Database Connectivity (RDBC) API
• Platform Layer (consensus, chain, network, notary)
• Transaction Layer (execution runtime and in-memory chain state)
• Storage Layer (chain and chain state durability)

NexRes v1.5.0

A complete refactoring of the code base such that (1) the core engine code is now moved to the platform folder, including the formwork architectures and protocols implementations; (2) the API/interface-related code is moved to the service folder, including UTXO, smart contract, and key-value interface; (3) the python SDK code is moved to a different repository here.

ResilientDB Legacy with SGX Acceleration (v3.1)

Creating a persistent release using Zenodo on the legacy codebase of ResilientDB (pre-NexRes).

NexRes v1.4.1

Creating a persistent release using Zenodo.
