DERO : A secure, private blockchain with smart-contracts
Usage:
derod [--help] [--version] [--testnet] [--debug] [--sync-node] [--fullnode] [--disable-checkpoints] [--socks-proxy=<socks_ip:port>] [--data-dir=<directory>] [--p2p-bind=<0.0.0.0:18089>] [--add-exclusive-node=<ip:port>]... [--add-priority-node=<ip:port>]... [--min-peers=<11>] [--rpc-bind=<127.0.0.1:9999>] [--node-tag=<unique name>] [--prune-history=<50>]
derod -h | --help
derod --version
Options:
-h --help Show this screen.
--version Show version.
--testnet Run in testnet mode.
--debug Debug mode enabled, print log messages
--fullnode Full node mode (this option has effect only while bootstrapping)
--socks-proxy=<socks_ip:port> Use a proxy to connect to network.
--data-dir=<directory> Store blockchain data at this location
--rpc-bind=<127.0.0.1:9999> RPC listens on this ip:port
--p2p-bind=<0.0.0.0:18089> p2p server listens on this ip:port, specify port 0 to disable listening server
--add-exclusive-node=<ip:port> Connect to specific peer only
--add-priority-node=<ip:port> Maintain persistant connection to specified peer
--sync-node Sync node automatically with the seeds nodes. This option is for rare use.
--node-tag=<unique name> Unique name of node, visible to everyone
--prune-history=<50> prunes blockchain history until the specific topo_height
