Start a Hush Daemon

OPTIONS

This help message

Execute command when the best block changes (%s in cmd is replaced by block hash)

How many blocks to check at startup (default: 288, 0 = all)

How thorough the block verification of -checkblocks is (0-4, default: 3)

Full node client name, default ’GoldenSandtrout’

Specify configuration file (default: HUSH3.conf)

Run in the background as a daemon and accept commands

Specify data directory (this path cannot use ’˜’)

Specify directory to be used when exporting data

Set database cache size in megabytes (4 to 16384, default: 512)

Keep at most <n> unconnectable transactions in memory (default: 100)

Specify the maximum length of a blockchain re-organization

[DEPRECATED/IGNORED] Set the maximum number of transparent inputs in a transaction that the mempool will accept (default: 0 = no limit applied)

Set the number of script verification threads (-8 to 16, 0 = auto, <0 = leave that many cores free, default: 0)

Specify pid file (default: hushd.pid)

Execute command when transaction expires (%s in cmd is replaced by transaction id)

Reduce storage requirements by pruning (deleting) old blocks. This mode disables wallet support and is incompatible with -txindex. Warning: Reverting this setting requires re-downloading the entire blockchain. (default: 0 = disable pruning blocks, >550 = target size in MiB to use for block files)

Rebuild block chain index from current blk000??.dat files on startup

Create new files with system default permissions, instead of umask 077 (only effective with disabled wallet functionality)

Maintain a full transaction index, used by the getrawtransaction rpc call (default: 0)

Maintain a timestamp index for block hashes, used to query blocks hashes by a range of timestamps (default: 0)

Maintain a full spent index, used to query the spending txid and input index for an outpoint (default: 0)

Maintain extra statistics about shielded transactions and payments (default: 0)

Connection options:

Add a node to connect to and attempt to keep the connection open

Specify ASN mapping used for bucketing of the peers (default: asmap.dat). Relative paths will be prefixed by the net-specific datadir location.

Threshold for disconnecting misbehaving peers (default: 100)

Enable NSPV messages processing (default: true when -ac_private=1, otherwise false)

I2P SAM proxy to reach I2P peers and accept I2P connections (default: none)

If set and -i2psam is also set then incoming I2P connections are accepted via the SAM proxy. If this is not set but -i2psam is set then only outgoing connections will be made to the I2P network. Ignored if -i2psam is not set. Listening for incoming I2P connections is done through the SAM proxy, not by binding to a local address and port (default: 1)

Relay non-P2SH multisig (default: 1)

Support filtering of blocks and transaction with Bloom filters (default: 1)

Listen for connections on <port> (default: 55555 or testnet: 55420)

Connect through SOCKS5 proxy

Randomize credentials for every proxy connection. This enables Tor stream isolation (default: 1)

Connect to a node to retrieve peer addresses, and disconnect

Specify connection timeout in milliseconds (minimum: 1, default: 60000)

Tor control port to use if onion listening enabled (default: 127.0.0.1:9051)

Password for a private key encryption (default: not set, i.e. private key will be stored unencrypted)

Full path to a certificate

Full path to a trusted certificates directory

Bind to given address and allowlist peers connecting to it. Use [host]:port notation for IPv6

Allowlist peers connecting from the given netmask or IP address. Can be specified multiple times. Allowlisted peers cannot be DoS banned and their transactions are always relayed, even if they are already in the mempool, useful e.g. for a gateway

Wallet options:

Do not load the wallet and disable wallet RPC calls

Set key pool size to <n> (default: 100)

Enable auto Sapling note consolidation (default: false)

Block interval between consolidations (default: 25)

Rescan the block chain for missing wallet transactions on startup

Rescan from specified height when rescan=1 on startup

Attempt to recover private keys from a corrupt wallet.dat on startup

Send transactions as zero-fee transactions if possible (default: 0)

Spend unconfirmed change when sending transactions (default: 1)

If paytxfee is not set, include enough fee so transactions begin confirmation on average within n blocks (default: 2)

Set the number of blocks after which a transaction that has not been mined will become invalid (default: 200)

Maximum total fees (in HUSH) to use in a single wallet transaction; setting this too low may abort large transactions (default: 0.10)

Upgrade wallet to latest format on startup

Specify wallet file absolute path or a path relative to the data directory (default: wallet.dat)

Make the wallet broadcast transactions (default: 1)

Execute command when a wallet transaction changes (%s in cmd is replaced by TxID)

Enable the wallet filter for notary nodes and add one Raddress to the allowlist of the wallet filter. If -allowlistaddress= is used, then the wallet filter is automatically activated. Several Raddresses can be defined using several -allowlistaddress= (similar to -addnode). The wallet filter will filter the utxo to only ones coming from my own Raddress (derived from pubkey) and each Raddress defined using -allowlistaddress= this option is mostly for Notary Nodes).

Delete all wallet transactions and only recover those parts of the blockchain through -rescan on startup (1 = keep tx meta data e.g. account owner and payment request information, 2 = drop tx meta data)
