      --bootstrap-ip string        default bootstrap server to interconnect peers (default "127.0.0.1")
      --bootstrap-port uint        default bootstrap server port to interconnect peers (default 8080)
      --datadir string             Absolute path to the node data dit where the DB will be stored
  -h, --help                       help for run
      --ip string                  exposed IP for communication with peers (default "127.0.0.1")

Notes

The genesis block can be found at database/genesis.json
To modify the network difficulty, modify the IsBlockHashValid function in database/state.go

Tests

Run all tests with verbosity but one at a time (without timeout as mining takes time), to avoid ports collisions:

go test -v -p=1 -timeout=0 ./...

Run an individual test:

go test -timeout=0 ./node -test.v -test.run ^TestNode_Mining$

Note: Majority are integration tests and will take time to run, due to mining. Some accounts have been added to the repository as test accounts.
