Sovereign Tech Fund invests in Pendulum
Sovereign Tech Fund will support our effort to build modern and memory-safe implementations of the Network Time Protocol (NTP) and the Precision Time Protocol (PTP).

NTP and PTP are vital building blocks of the internet and other critical infrastructure, providing accurate and reliable time synchronization on millions of phones, PCs, servers and networks.

STF's €440k investment enables us to continue the development, adoption and maintenance of Statime (PTP) and ntpd-rs (NTP), the two projects that constitute Pendulum, throughout 2023 and 2024.

We’re very thankful that STF are advocating the importance of making these protocols secure and reliable and are investing in our efforts.

The work

1. Development and Stabilization

  • Releasing end-user ready version of ntpd-rs with improved stability, observability, and configuration.
  • Releasing PTP functionality for Linux through Statime.
  • Contributing to the NTPv5 standard, implementing the draft specification, and improving the custom clock algorithm based on Kalman filters.

2. Adoption and Visibility:

  • Promoting adoption by improving packaging and documentation, conducting market research, and showcasing performance and statistics.
  • Blog posts, talks, and documentation on the benefits of using memory-safe versions of PTP and NTP.
  • Exploring the establishment of an NTS (Network Time Security) pool to facilitate the adoption of NTS.

3. Maintenance and Community Support:

  • Ensuring ongoing maintenance of both Statime and ntpd-rs by responding to issues, updating documentation, and performing regular releases.
  • Transferring knowledge to contributors and fostering community engagement.
  • Seeking structural financial support from industry companies to sustain the projects in the long term.

About Pendulum and Tweede golf

Pendulum is a project by Tweede golf. Tweede golf is an expert in the Rust programming language and the development of secure digital infrastructure software.

At the beginning of 2022 the development of PTP started, supported by funding of the NLnet Foundation. In April of that year we started to work on NTP, as contractor for Prossimo's NTP initiative. In 2023 both projects came under Tweede golf's wings and found their home in Pendulum.

We're happy to announce that the Internet Security Research Group has officially made us the maintainers of the open-source memory-safe implementation of NTP, ntpd-rs. As such, we are now also looking for early adopters.

The implementation includes a server and client, as well as full support for Network Time Security (NTS), which brings encryption and greater integrity to time synchronization. Timing is precise and stable, as reflected by excellent performance in the NTP pool.

For the last couple of months, we've been working on a Rust implementation of the Precision Time Protocol called Statime ("statim" is Latin for immediately), and we're proud to announce the completion of the first phase of the project.
The internet has a hole at the bottom of its trust stack, and we need to do something about it. In particular, the internet needs secure time synchronization to fortify the security of our digital world. In this article, we present a path towards the adoption of securely synchronized time.
