Change Log

Apache ResilientDB v1.11.0 (2025-4-27)

Apache ResilientDB v1.10.1 (2024-4-16)

• Remove the binary keys from the source code. (Junchao Chen)
• Fix few bugs on Docker and performance tools. (Gopal Nambiar, Junchao Chen)

Apache ResilientDB v1.10.0 (2024-4-16)

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 (2023-11-29)

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 (2023-08-21)

Implemented Enhancements: 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 (2023-08-04)

Implemented Enhancements: For each replica local recovery from durable storage upon system restart was added.(Junchao Chen)

NexRes v1.6.0 (2023-05-30)

Implemented Enhancements: Refactoring and enhancement of the codebase to highlight the entire software stack of ResilientDB consisting of the following layers (Junchao Chen)

• 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 (2023-04-04)

Implemented Enhancements:

• A complete refactoring of the codebase 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 (Junchao Chen).

NexRes v1.4.0 (2023-02-28)

Major Changes

• Support of UTXO model and wallet integration: Detailed Documentation (Junchao Chen)

NexRes v1.3.0 (2023-02-22)

Implemented Enhancements:

• Added Python SDK that supports UTXO-like transactions such as asset creation, transfer, and multi-party validations. (Arindaam Roy, Glenn Chen, and Julieta Duarte)
• Added REST CROW endpoints to interface with the on-chain KV service. (Glenn Chen and Julieta Duarte)
• Extended KV service range queries. (Glenn Chen and Julieta Duarte)

Fixed Bugs:

• Fixed KV service queries on all values retrieving empty placeholder values (Glenn Chen)

NexRes v1.2.0 (2023-01-29)

Implemented Enhancements:

• Support smart contract compiled from Solidity. (Junchao Chen)
• Use eEVM as a back-end service to execute the contract functions. (Junchao Chen)

NexRes v1.1.0 (2023-01-03)

Implemented Enhancements:

• Added Geo-Scale Byzantine Fault-tolerant consensus protocol, referred to as GeoBFT. It is designed for excellent scalability by using a topological-aware grouping of replicas in local clusters, giving rise to parallelization of consensus at the local level and by minimizing communication between clusters. (WayneWang)
