# 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.
## 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://127.0.0.1:26658"
# 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

##### advanced configuration options #####
##### rpc server configuration options #####

# you increase your OS limits.

# Maximum number of simultaneous connections (including WebSocket).
# Does not include gRPC connections. See grpc_max_open_connections

# Set true for strict address routability rules

# Time to wait before flushing messages out on the connection, in ms

# Maximum number of peers to connect to

# Maximum size of a message packet payload, in bytes
max_packet_msg_payload_size = 1024
# Rate at which packets can be sent, in bytes/second

# Rate at which packets can be received, in bytes/second
recv_rate = 512000
# Set true to enable the peer-exchange reactor

# peers. If another node asks it for addresses, it responds and disconnects.
#
# Does not work if the peer-exchange reactor is disabled.

##### mempool configuration options #####

##### transactions indexer configuration options #####
[tx_index]
# What indexer to use for transactions
#
# Options:
# 1) "null"
# 2) "kv" (default) - the simplest possible indexer, backed by key-value storage (defaults to levelDB; see DBBackend).

# Comma-separated list of tags to index (by default the only tag is tx hash)
#
# It's recommended to index only a subset of tags due to possible memory
# bloat. This is, of course, depends on the indexer's DB and the volume of
# transactions.
index_tags = ""
# 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).

##### instrumentation configuration options #####

# PrometheusListenAddr.
# Check out the documentation for the list of available metrics.
