bitcoind does what you need.  From "bitcoind --help":

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

Then whenever you're notified of a new block use getreceivedbyaddress or listreceivedbyaddress to see if your address has received anything.

is there any way to get a json representation of a specific block which includes all transaction in it?

Yes, getblock does exactly that.

thanks

i dont have a bitcoind here right now and the internet says "getblock" is not available.

hello,

i want to write a small program which track bitcoin blocks and looks for certain addresses.
what is the easiest way to get notified when a new block arrives?

i'd prefer to run a stock bitcoind.

with "getinfo" i get the current block count.
is there any way to get a json representation of a specific block which includes all transaction in it?

(notification or polling does not really matter. its not that time sensitive)
