 Initially, we focused our work on achieving high transaction throughput, low latency, and resilience against multiple geographical datacenter outages without significant downtime or any data loss.
 The design decisions we made to achieve these goals will help inform policy makers around the world about the spectrum of tradeoffs and available options for CBDC design.

    Note that this script is just a convenience to install system-wide dependencies we expect.
    As a result, it uses the system package manager, requires `sudo`, and should only be run **once**.
    ```console
    # ./scripts/install-build-tools.sh
    ```
 1. Setup project dependencies
-   This script builds and installs a local copy of several build-dependencies which are not widely packaged.
-   Because it installs to a local, configurable prefix (defaulting to `./prefix`), it does not need root permissions to run.
-   Furthermore, it should always be safe to delete `prefix` and rerun this script.
