    Snapshot validator for Lisk

    Build Status npm version

    Double check your snapshots!

    A tool to validate the data integrity of a Lisk snapshot.

    Security note: even though this tool checks a lot of data consistency, it is far from perfect. Thus a validated snapshot can still contain corrupted data. Thus keep choosing snapshot providers wisely.

    Design principles

    • Read-only (does not produce or change snapshots)
    • Fast runtime (validates 10k blocks/second on a 4 year old laptop)
    • Independent development (to avoid copying bugs)
    • Return code is king: 0 for success, everything else for error (output text is debugging only)

    Prerequirements

    • A postgres server must be running
    • createdb test_database_xyz must work for the current user

    How to install/compile

    • Install libpq-dev, libsodium-dev, pkg-config, cmake, a C++ compiler, and Python, using your favourite package manager.
    • git clone --recursive https://github.com/prolina-foundation/snapshot-validator.git
    • cd snapshot-validator/external/libpqxx
    • ./configure --disable-documentation --prefix="$PWD/../libpqxx-installation" && make -j 4 install
    • cd ../..
    • mkdir build && cd build
    • cmake -DCMAKE_BUILD_TYPE=Release .. && make -j 4
    • Now move the resulting binary validate-snapshot-database into PATH, e.g. sudo mv validate-snapshot-database /usr/local/bin

    How to use

    • Ensure validate-snapshot-database is in PATH: validate-snapshot-database --help
    • Run ./validate-snapshot-file testnet <testnet snapshot file>

    Further notes

    • Temporary databases are not dropped when validation fails. Use a Postgres management tool like e.g. pgAdmin to clean up from time to time.
    • Mainnet validation consumes 4.5 GiB of memory on Linux because all transactions are kept in memory
