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
