Default config file path is $HOME/.aion/config.toml .
You can create and fill parameters you want in it.
If $HOME/.aion/config.toml doesn't exist when start aion, it will automatically generate a default config file on the default config file path.
You can also use $ ./aion --default-config to create a new default config as $HOME/.aion/default_config.toml
It will list all parameters with default value .
Note that parameters which default value is None will be presented as comments.
You can use $ ./aion --default-config="YOUR_CONFIG_PATH" to start aion with the config file you specified.
You can use $ ./aion --no-config to start aion without config file.

- e.g.:
--tx-gas-limit=100000000000
Apply a limit of GAS as the maximum amount of gas a single transaction may have for it to be mined.
config:
[mining] #tx_gas_limit = None
- e.g.:
tx_gas_limit = "100000000000"
$ aion --tx-time-limit=[MS]
- e.g.:
--tx-time-limit=600
Maximal time for processing single transaction. If enabled senders/recipients/code of transactions offending the limit will be banned from being included in transaction queue for 180 seconds.
config:
[mining] #tx_time_limit = None
- e.g.:
tx_time_limit = 600
$ aion --extra-data=[STRING]
- e.g.:
--extra-data="aion"
Specify a custom extra-data for authored blocks, no more than 32 characters.
config:
[mining] #extra_data = None
- e.g.:
extra_data = "aion"
config:
[db]
$ aion --disable-wal
Disables DB WAL, which gives a significant speed up but means an unclean exit is unrecoverable.
config:
[db] disable_wal = false
$ aion --scale-verifiers
Automatically scale amount of verifier threads based on workload. Not guaranteed to be faster.
config:
[db] scale_verifiers = false
$ aion --pruning=[METHOD]
- e.g.:
--pruning=archive
Configure pruning of the state/storage trie. METHOD may be one of auto, archive, fast: archive - keep all state trie data. No pruning. fast - maintain journal overlay. Fast but 50MB used. auto - use the method most recently synced or default to fast if none synced.
default: "archive"
config:
[db] pruning = "archive"
$ aion --pruning-history=[NUM]
- e.g.:
--pruning-history=64
Set a minimum number of recent states to keep when pruning is active.
default: 64
config:
[db] pruning_history = 64
$ aion --pruning-memory=[MB]
- e.g.:
--pruning-memory=32
The ideal amount of memory in megabytes to use to store recent states. As many states as possible will be kept within this limit, and at least --pruning-history states will always be kept.
default: 32
config:
[db] pruning_memory = 32
$ aion --cache-size-blocks=[MB]
- e.g.:
--cache-size-blocks=8
Specify the prefered size of the blockchain cache in megabytes.
default: 8
config:
[db] cache_size_blocks = 8
$ aion --cache-size-queue=[MB]
- e.g.:
--cache-size-queue=40
Specify the maximum size of memory to use for block queue.
default: 40
config:
[db] cache_size_queue = 40
$ aion --cache-size-state=[MB]
- e.g.:
--cache-size-state=25
Specify the maximum size of memory to use for the state cache.
default: 25
config:
[db] cache_size_state = 25
$ aion --db-compaction=[TYPE]
- e.g.:
--db-compaction=auto
Database compaction type. TYPE may be one of: ssd - suitable for SSDs and fast HDDs; hdd - suitable for slow HDDs; auto - determine automatically.
default: "auto"
config:
[db] db_compaction = "auto"
$ aion --fat-db=[BOOL]
- e.g.:
--fat-db=auto
Build appropriate information to allow enumeration of all accounts and storage keys. Doubles the size of the state database. BOOL may be one of on, off or auto.
default: "auto"
config:
[db] fat_db = "auto"
$ aion --cache-size=[MB]
- e.g.:
--cache-size=64
Set total amount of discretionary memory to use for the entire system, overrides other cache and queue options.
config:
[db] #cache_size = None
- e.g.:
cache_size =64
$ aion --num-verifiers=[INT]
- e.g.:
--num-verifiers=5
Amount of verifier threads to use or to begin with, if verifier auto-scaling is enabled.
config:
[db] #num_verifiers = None
- e.g.:
num_verifiers = 5
config:
[log]
Since OANr-v1.1, a new log framework is used aiming at log division and compression. And new config grammar is introduced, namely yaml which is widely used as format of configuration.
$ aion --log-config="log_file_path"
- e.g.:
--log-config="/var/aionr/log"
config:
[log] config = "log_config.yaml"
