Data visualization

We are excited to present our inaugural report on the state of open source software (OSS) projects building on Arbitrum. This analysis is the first in a series aimed at providing the community with data and insights to assist with impact measurement and grantmaking.

Some highlights:

1. We are currently tracking over 300 OSS projects and over 13,000 code artifacts that are making an impact on the Arbitrum ecosystem. These artifacts include both GitHub repos (~10,000) and smart contracts deployed on Arbitrum One (~3,000).
2. Approximately 1,800 developers are actively engaged in these projects. This number aligns closely with the latest Electric Capital Developer Report. Our analysis, however, incorporates an additional 94 projects not currently captured in their registry.
3. The number of active developers is 18% lower than the peak of around 2,200 in March 2023. It's important to note, however, that this reduction is primarily concentrated in a few projects rather than a general decline across the ecosystem. In fact, the majority of projects have maintained a stable developer count over the past year.

RetroPGF generated a considerable amount of noise, both during and after the main event. Now that the results are in, we need to find the signal. These are the messages, intended or not, that will likely reach the wider community.

We can learn a lot by plotting and analyzing the distribution patterns of tokens to projects. In domains where the signal is too weak (ie, impact > profit) or too strong (ie, profit > impact), the Collective should be more explicit in shaping the distribution patterns it wants to see and then making tweaks to the RetroPGF process and game design.

In this post we will take a look at:

1. 30,000 foot view: the signals that everyone in crypto should pick up on
2. Box seat view: the signals that badgeholders and engaged community members should pick up on
3. In the arena view: the signals that live players and builders should pick up on

I also want to make sure I don’t bury the lead:

• Less than 20% of the RetroPGF 3 allocation went to projects that directly contribute to sequencer fees.
• Every badgeholder and citizen who wants the best for Optimism probably feels that this allocation level is too low.
• This is not a sustainable trend, given that sequencer fees are the long-term revenue engine for this whole experiment.

Many factors likely contributed to this outcome. In a previous blog post, we discussed how the round’s game dynamics could make it difficult for voters to express their true preferences.

Open Source Observer is a platform for measuring the impact of open source software (OSS) contributions. We launched a few months ago with a commitment to open source everything. We attended the PL Summit in Istanbul last month and had a chance to present our work to the community.

We are excited to announce that we are now initiating coverage of the PLN open source economy!

Heatmap of all GitHub contributions to PLN open source projects since 2017.

This report is a shallow dive on 188 open source software projects that we are currently tracking within the PLN ecosystem. We are also tracking 1,000+ projects in the broader crypto economy, which we will cover in seperate reports.

Open Source Observer is a platform for measuring the impact of open source software (OSS) contributions. We launched a few months ago with a commitment to open source everything. Here is our hello world post on the forum ICYMI.

This report is a shallow dive on the 300+ open source software projects participating in the latest round of retroactive public goods funding (RetroPGF 3). It combines both off- and onchain data about projects.

The report itself has two objectives:

• Kickstart more rigorous analysis on the effectiveness of RetroPGF as a mechanism
• Snipe some data nerds to join our data collective

Let’s jump in.
