Meaning of H and "Nounce" parameters? #63

Closed moxious closed 7 years ago

moxious commented 7 years ago

In data coming back via web sockets, we see things like this:

{"H":"CoreHub","M":"updateExchangeState","A":[{"MarketName":"USDT-ZEC","Nounce":73530,"Buys":[{"Type":0,"Rate":249.56100001,"Quantity":4.10941386}],"Sells":[{"Type":0,"Rate":253.944,"Quantity":14.903},{"Type":1,"Rate":253.945,"Quantity":0},{"Type":0,"Rate":253.94597411,"Quantity":6.366}],"Fills":[]}]}

What here does "H" stand for, and what other values are there besides CoreHub? Additionally, what does the Nounce value signify?

The H signifies the Hub/Channel the message came from. CoreHub is the only hub available so the value will always be that.

Nounce is an id that can only be used once https://en.wikipedia.org/wiki/Cryptographic_nonce
