Stellar Dev Digest: Issue #36

Importance of community, new Stellar Core release, building a Cash App on Stellar.

Hey everyone! Welcome to another issue of the Stellar Dev Digest, a weekly recap of all things related to the development of the Stellar Network.

What is Stellar? Stellar is a platform that connects banks, payment systems, and people. Integrate to move money quickly, reliably, and at almost no cost.

News & Posts of the Week

  • In light of the events around COVID-19, SDF’s CEO and Executive Director Denelle Dixon put out a blog post that highlights the importance and resilience of community when faced with new challenges. — You can read it here.
  • On last week’s episode of the Stellar Podcast, Tyler and I discussed upcoming live events, the Stellar Community Fund, and how a Cash App could be built on Stellar using SEP24 and path payments. — Listen to the episode here.
  • I also want to draw special attention to the new Stellar Podcast YouTube channel! If YouTube is your platform of choice, make sure to subscribe to get the latest episodes and updates on live episodes! — Subscribe here.
  • If you missed the webinar SDF’s Senior Strategist, Lisa Nestor, did with Cowrie about their cross-border payment services for Nigeria — don’t worry. We released a full recap and recording of the event! — Find the recap here.

Application of the Week

This week I’m featuring OpenSolar! — A project by Yale OpenLab that aims to democratize energy.

In areas where infrastructure providing electricity is underdeveloped or has been destroyed, solar power is starting to look like an appealing option. The only problem is that solar power is expensive, and lowering that cost is a pressing issue. OpenSolar’s platform intends to do just that by streamlining the flow of crowd-based funds (e.g. bonds or equity) to finance the deployment of solar assets.

In order to reliably facilitate this flow of funds, OpenSolar is using Stellar as their payment backend — making cheap cross-border investments and payments possible. To find out more about OpenSolar you can watch their demo here and read about their project here.

Releases and Updates

I mentioned last week that Stellar Core v12.5.0 was coming soon and I would never lie to you. v12.5.0 is out now and it includes a number of new features including new SCP metrics, improved catch-up logging, SCP code cleanup and more. Make sure to update to the latest version!

In other news, CAP-0015: Fee Bump Transactions has been implemented and will be included in Protocol 13 (discussed in issue #34). If you’re unfamiliar with CAP-0015, the short explanation is that it allows an arbitrary account to pay the fee for a transaction.

This means that in the event a pre-authorized transaction (e.g. the release of escrow funds) cannot be executed due to an increases in fees, someone can use a fee bump transaction to increase the fee and resolve the issue.

Additionally, this will allow services to directly pay for their users’ fees if they so choose. Currently, services have to send their users lumens and hope they use them for fees — a clunky experience. CAP-0015 will provide an elegant solution to this problem and improve this area of the user onboarding experience.

Last but not least, horizonclient (a Stellar Go SDK package) v2.2.0 and JavaScript Stellar SDK v4.1.0 are both released and ready for use. These two releases add SEP-0029 support which describes a standard way to check if a memo is required before sending a transaction.

Active Discussions

💬 It only seems fair that I spend one more week highlighting the discussion period for the Stellar Community Fund!

After submissions closed last week, a discussion period opened up on Galactic Talk. It lasts until April 20, and gives the community a chance to ask questions and give feedback that could help guide voting decisions come April.

Not only will this feedback affect voting decisions, it will also help participants improve their projects! Without community feedback, it’s hard to know where an idea stands or what should be fixed or made better.

👉 Don’t hesitate to jump in and give your thoughts! You can find the full list of proposals here.
