Partially open source
The service will scan the network and try to find out all the RPC nodes. Sort the RPC nodes and establish a DRPC proxy server with these nodes which have the lowest latency.
Nodes are auto reweighted by latency and kicked out by status if not synced up.
"Keep your service always online", that is what DRPC does.
- Dashboard: a web UI for the service
- Upstream: dispatch http jsonrpc to http backends
- Expose http jsonrpc interfaces
- Load-balance: WeightedRound-Robin algorithm
- Statistic: calculate metrics, query and display on the dashboard
- Upstream: dispatch http or websocket jsonrpc to http or websocket backends
- Cache: cache responses to some methods
- Offline requests: serving by local block data storage
- Install Go
