  zcashd [options]                     Start Zcash Daemon


       This help message

       Receive and display P2P network alerts (default: 1)

       Execute command when a relevant alert is received or we see a really
       long fork (%s in cmd is replaced by 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)

       Specify configuration file (default: zcash.conf)

       Run in the background as a daemon and accept commands

       Specify data directory

       Set database cache size in megabytes (4 to 16384, default: 100)

       Imports blocks from external blk000??.dat file on startup

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

       Set the number of script verification threads (-1 to 16, 0 = auto, <0 =
       leave that many cores free, default: 0)

       Specify pid file (default: zcashd.pid)

       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)

Connection options:

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

       Threshold for disconnecting misbehaving peers (default: 100)

       Number of seconds to keep misbehaving peers from reconnecting (default:

       Bind to given address and always listen on it. Use [host]:port notation
       for IPv6

       Connect only to the specified node(s)

       Discover own IP addresses (default: 1 when listening and no -externalip
       or -proxy)

       Allow DNS lookups for -addnode, -seednode and -connect (default: 1)

       Query for peer addresses via DNS lookup, if low on addresses (default: 1
       unless -connect)

       Specify your own public address

       Always query for peer addresses via DNS lookup (default: 0)

       Accept connections from outside (default: 1 if no -proxy or -connect)

       Maintain at most <n> connections to peers (default: 125)

       Maximum per-connection receive buffer, <n>*1000 bytes (default: 5000)

       Maximum per-connection send buffer, <n>*1000 bytes (default: 1000)

       Use separate SOCKS5 proxy to reach peers via Tor hidden services
       (default: -proxy)

       Only connect to nodes in network <net> (ipv4, ipv6 or onion)

       Relay non-P2SH multisig (default: 1)

       Listen for connections on <port> (default: 8233 or testnet: 18233)

       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: 5000)

       Use UPnP to map the listening port (default: 0)

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

       Whitelist peers connecting from the given netmask or IP address. Can be
       specified multiple times. Whitelisted 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)

       Fee (in BTC/kB) to add to transactions you send (default: 0.00)

       Rescan the block chain for missing wallet transactions 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)

       Maximum total fees 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 (within 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)

       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)

Debugging/Testing options:

       Output debugging information (default: 0, supplying <category> is
       optional). If <category> is not supplied, output all debugging

       Shrink debug.log file on client startup (default: 1 when no -debug)

       Use the test network
