Configuration ============= Tendermint Core can be configured via a TOML file in ``$TMHOME/config/config.toml``. Some of these parameters can be overridden by command-line flags. For most users, the options in the ``##### main base configuration options #####`` are intended to be modified while config options further below are intended for advance power users. Config options ~~~~~~~~~~~~~~ The default configuration file create by ``tendermint init`` has all the parameters set with their default values. It will look something like the file below, however, double check by inspecting the ``config.toml`` created with your version of ``tendermint`` installed: :: # This is a TOML config file. # For more information, see https://github.com/toml-lang/toml ##### main base config options ##### # TCP or UNIX socket address of the ABCI application, # or the name of an ABCI application compiled in with the Tendermint binary proxy_app = "tcp://127.0.0.1:46658" # A custom human readable name for this node moniker = "anonymous" # If this node is many blocks behind the tip of the chain, FastSync # allows them to catchup quickly by downloading blocks in parallel # and verifying their commits fast_sync = true # Database backend: leveldb | memdb db_backend = "leveldb" # Database directory db_path = "data" # Output level for logging log_level = "state:info,*:error" ##### additional base config options ##### # The ID of the chain to join (should be signed with every transaction and vote) chain_id = "" # Path to the JSON file containing the initial validator set and other meta data genesis_file = "genesis.json" # Path to the JSON file containing the private key to use as a validator in the consensus protocol priv_validator_file = "priv_validator.json" # Mechanism to connect to the ABCI application: socket | grpc abci = "socket" # TCP or UNIX socket address for the profiling server to listen on prof_laddr = "" # If true, query the ABCI app on connecting to a new peer # so the app can decide if we should keep the connection or not filter_peers = false ##### advanced configuration options ##### ##### rpc server configuration options ##### [rpc] # TCP or UNIX socket address for the RPC server to listen on laddr = "tcp://0.0.0.0:46657" # TCP or UNIX socket address for the gRPC server to listen on # NOTE: This server only supports /broadcast_tx_commit grpc_laddr = "" # Activate unsafe RPC commands like /dial_seeds and /unsafe_flush_mempool unsafe = false ##### peer to peer configuration options ##### [p2p] # Address to listen for incoming connections laddr = "tcp://0.0.0.0:46656" # Comma separated list of seed nodes to connect to seeds = "" # Comma separated list of nodes to keep persistent connections to # Do not add private peers to this list if you don't want them advertised persistent_peers = "" # Path to address book addr_book_file = "addrbook.json" # Set true for strict address routability rules addr_book_strict = true # Time to wait before flushing messages out on the connection, in ms flush_throttle_timeout = 100 # Maximum number of peers to connect to max_num_peers = 50 # Maximum size of a message packet payload, in bytes max_msg_packet_payload_size = 1024 # Rate at which packets can be sent, in bytes/second send_rate = 512000 # Rate at which packets can be received, in bytes/second recv_rate = 512000 # Set true to enable the peer-exchange reactor pex = true # Seed mode, in which node constantly crawls the network and looks for # peers.

This is, of course, depends on the indexer's DB and the volume of # transactions. index_tags = "{{ .TxIndex.IndexTags }}" # When set to true, tells indexer to index all tags. Note this may be not # desirable (see the comment above). IndexTags has a precedence over # IndexAllTags (i.e. when given both, IndexTags will be indexed). index_all_tags = {{ .TxIndex.IndexAllTags }}
