Beam Node Explorer API

Beam Node Explorer API

The Node Explorer provides information about current chain state and blocks.

How to use

Find explorer-node binary in the explorer subdirectory and run with the following arguments:

Node explorer options:
  -h [ --help ]                      list of all options
  --peer arg (=172.104.249.212:8101) peer address
  --port arg (=10000)                port to start the local node on
  --api_port arg (=8888)             port to start the local api server on

./explorer-node.exe --peer eu-node01.mainnet.beam.mw:8100 --api_port=8080 for example.
It may take some time (a few hours) on the first start to load all the info from chain.
