Monthly Development Update — September 2020

September has been an amazing month for Swarm. Not only have we released Swarm Beta, which you are more than welcome to try out for yourself, but we’ve also held a day-long online launch event packed with workshops and talks. We’ve touched upon some very interesting aspects of Swarm, with a focus on the ecosystem and also our developer team demonstrated the new features in Beta.

We are inviting you to read the Swarm Beta release notes and the development update to see all the work that was done in the previous month.

Swarm Beta (Release v0.3.0) — Release Notes

Bee Beta contains the required features to build rich applications on top of Swarm. This release adds:

  • Bandwidth incentives (on the Görli test network) are enabled by default
  • Zero-leak messaging (Pss)
  • External signer support (Clef)
  • Improved sync and download performance
  • Breaking changes on protocol level (TL;DR — just update your nodes)

Try it out and get in touch at our BeeHive or Telegram!


Bee’s third release marks a major milestone of the Bee project; we believe that developers can now unleash rich applications over Swarm with a good balance of performance and security. We understand that as the Swarm ecosystem develops, developers might need access to low-level APIs in order to develop a rich application experience, we therefore also offer a set of low-level APIs that allow you to interact with the Swarm network in your own, custom way.

We invite you to use our APIs. Your feedback would be beneficial for us to further improve them in the future.

Breaking changes

Several breaking changes were introduced with this version. You are advised to update your nodes promptly.

Bandwidth incentives

Bee Beta contains the basis for the Swarm bandwidth incentives. You will now earn gBZZ (Görli BZZ) by running your Swarm node.

Conversely, you are required to pay with gBZZ in order to upload and download content. You can get gBZZ at our faucet — check our documentation on how to fund your node’s chequebook.

Zero-leak messaging

Bee Beta releases the second iteration of Pss (Postage service over swarm). Pss is zero-leak messaging over Swarm that allows for confidential, anonymous and untraceable node-to-node communication. Pss comes with a websocket API that allows clients to send a message to a recipient on an overlay address as well as to subscribe to a topic and receive messages.

External signer

Bee now supports an external signer (Clef) for security reasons to allow private keys not to be exposed to the client process.

Speed improvements

Uploading and downloading data to Bee is now significantly more performant than it used to be(e).


All new features are documented in our documentation.
