# Daemon Flags

For a full list of daemon flags, open a command line or terminal and run:

	xayad -?

You can also consult the [Bitcoin documentation here](https://bitcoin.org/en/developer-reference). 

The following documents the most important differences between xayad and bitcoind.

For standard startup flags needed for XAYA, consult [Startup Flags in Prerequisites](Prerequisites#Startup-Flags).

# Unique to XAYA

There are several flags and options that are unique to XAYA and xayad.

## Options

-  `-namehistory`: Keep track of the full name history (default: 0)

The namehistory flag allows getting the entire history for a name. However, this increases the database size a little bit. Use the 'name_history <name>` in an RPC or in xaya-cli to get the complete history. 

## ZeroMQ notification options

-  `-trackgame=<game>`: Enable tracking of the listed game for the XAYA game interface
-   `-zmqpubgameblocks=<address>`: Enable publication of game data for block attach/detach events in `<address>`

## RPC server options

-  `-maxgameblockattaches=<n>`: Sets the maximum number of attach steps sent for a single `game_sendupdates` request (default: 1000)
-  `-nameencoding=<enc>`: Sets the default encoding used for names in the RPC interface (default: utf8)
-  `-valueencoding=<enc>`: Sets the default encoding used for values in the RPC interface (default: ascii)

## Debugging/Testing options

-  `-debug=<category>`
       Output debugging information (default: -nodebug, supplying <category> is
       optional). If <category> is not supplied or if <category> = 1,
       output all debugging information. <category> can be: net, tor,
       mempool, http, bench, zmq, db, rpc, estimatefee, addrman,
       selectcoins, reindex, cmpctblock, rand, prune, proxy, mempoolrej,
       libevent, coindb, qt, leveldb, **names, game**.

The "names" and "game" categories are added to the debug option in XAYA, but are not found in Bitcoin. 

## Block creation options

-  `-blockmaxweight=<n>`: Set maximum BIP141 block weight (default: 396000)

The maximum in Bitcoin is 3996000. XAYA has smaller, faster blocks, so hence the difference. 

## Wallet options

-  `-addresstype`: What type of addresses to use ("legacy", "p2sh-segwit", or "bech32", default: "legacy")

The default in XAYA is "legacy", however the default in Bitcoin is "p2sh-segwit". 

## Ports

-  `-port=<port>`: Listen for connections on <port> (default: 8394, testnet: 18394, regtest: 18495)
-  `-rpcport=<port>`: Listen for JSON-RPC connections on <port> (default: 8396, testnet: 18396, regtest: 18493)

Port numbers differ between XAYA and Bitcoin.
