Swarm Development Update — April 2020

Here is the latest update on the work that was done in April 2020. The team is working on the development of the Bee client and there is a good progress on global pinning too.

Bee project:

  • Added low-level chunk upload and download endpoints to HTTP API.
  • Added chunk persistence by porting existing solutions, localstore and shed packages, from the swarm project and adjusting to the new code organization.
  • Added a connection breaker component that makes the node more resilient to a large number of potential connectivity related problems.
  • Improving connections handling to the bootnodes when the node starts. As well adding more error-resilient connectivity strategies on libp2p level.
  • Added addressbook persistence. Addressbook is a component that stores underlay addresses about known peers.
  • Added the first and simple netstore implementation. Netstore is a component that fetches the chunk from the p2p network if the chunk is not found in the node’s localstore.
  • Added simple file joiner implementation and integrated to the codebase. This is the first step to have file operations on the exposed HTTP API.
  • Added a general purpose state store, mostly ported from the swarm codebase.
  • Progressing in replacing LevelDB with BadgerDB for chunk storage, but the effort is still on-going. A proper performance testing is planned to be performed when more chunk and file related functionalities are added to the codebase.
  • Added more functionalities to the debug API to be used by integration tests, such as node addressing information and whether the chunk is stored by the node.
  • Connected tracing identifiers with log messages to correlate events.
  • Added explicit coding guidelines in the project repository.
  • A number of improvements related to unit testing.

Incentives/persisence:

  • Huge progress on global pinning.
  • PSS is redesigned, initial stage curtailed for global pinning requirements.
  • Implemented trojan chunks.
  • Add PSS monitoring capabilities to monitor the state of the sent trojan chunk.
  • Completed observability stack for Bee project (prometheus, loki, jaeger and grafana)
  • Had presentation/demo — How to use observability stack for debugging purposes
  • Released new version of Bee Helm chart
  • Setup bee-staging project for easier Bee deployments and testing
  • Had presentation/demo — How to use bee-staging
  • Started Beekeeper project for Bee integration testing
  • Released Beekeeper v0.1.0 with peer count test available
  • Setup static code analysis tool for Bee project (deepsource.io)
  • Create eks-local-disk-provisioner for better utilization of NVME SSD disks in EKS cluster
  • Extended registration of ENS domains
  • Created DevOps Roadmap
  • Designed the bonding curve for the emission of Swarm token (BZZ)
  • Did some numerical stress-tests in gnu bc
  • Discussed and validated the design with experts in the field
  • Finished the design and architecture part of the Book of Swarm, specs are in the making
