Skale Consensus

Skale Consensus is an open-source C++ blockchain consensus engine for the SKALE ecosystem that coordinates block proposals and commitment using an asynchronous Byzantine fault-tolerant design.

Understand the project

Practical overview

When it fits

Use the repository when you need to inspect or build the SKALE consensus implementation, study its protocol specification, or work with its documented test workflows.

Who it is for

  • Blockchain developers exploring or integrating a consensus engine into a SKALE-compatible node.
  • Engineers studying asynchronous Byzantine agreement, block finality or consensus behavior.
  • Developers building and examining multi-node consensus tests.

Documented uses

  • Review the protocol specification and C++ implementation.
  • Build the engine from source in the documented Ubuntu environment.
  • Run the included unit, integration, end-to-end and tagged test suites.
  • Use the testing guide to investigate multi-node scenarios, including SGX simulation.
Before you choose

Requirements & limits

The repository is public and identifies its license as AGPL-3.0.

  • The implementation is written in C++ and the preferred build environment is Ubuntu 22.04.
  • The design describes asynchronous Byzantine Binary Agreement, BLS signatures and threshold encryption.
  • The repository includes specification and test resources as well as implementation code.
  • The README's performance and resilience statements are project claims, not independently verified results.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Build the consensus engine from source

Configure and compile the repository in Debug mode on the documented Ubuntu environment.

Before you start

  • Ubuntu 22.04 is the preferred documented environment.
  • Install the packages listed in the repository README, including GCC 11, CMake, Git and the specified development libraries.

Steps

  1. Clone the repository with its submodules using the README command.

  2. Build dependencies in debug mode from the deps directory with ./build.sh DEBUG=1.

  3. Configure a Debug CMake build with cmake . -Bbuild -DCMAKE_BUILD_TYPE=Debug.

  4. Build all targets with cmake --build build -- -j$(nproc).

Expected outcome

A Debug build of the repository's targets.

Guide limitations

  • The README says later Ubuntu versions may work but are not officially tested.
  • These are repository instructions, not a report of an independently performed build.

Run the documented one-node basic test

Use the built test executable for the README's basic one-node test invocation.

Before you start

  • Complete the repository build first.
  • The README's invocation uses sudo and runs from test/onenode.

Steps

  1. Change to the test/onenode directory.

  2. Run the documented command with NO_ULIMIT_CHECK=1, TEST_TIME_S=60 and TEST_TRANSACTIONS_PER_BLOCK=10, passing [consensus-basic] to ../../build/consensust.

Expected outcome

The basic one-node test is invoked with the README's stated duration and transactions-per-block setting.

Guide limitations

  • The README does not state a test result in the cited instructions.
  • The more detailed multi-node scenarios are covered separately in TESTING.md.
