SIGHASH_ALL

This is the default. It indicates that everything about the transaction is signed, except for the input scripts. Signing the input scripts as well would obviously make it impossible to construct a transaction, so they are always blanked out. Note, though, that other properties of the input, like the connected output and sequence numbers, are signed; it's only the scripts that are not. Intuitively, it means "I agree to put my money in, if everyone puts their money in and the outputs are this".

SIGHASH_NONE

The outputs are not signed and can be anything. Use this to indicate "I agree to put my money in, as long as everyone puts their money in, but I don't care what's done with the output". This mode allows others to update the transaction by changing their inputs sequence numbers.

SIGHASH_SINGLE

Like SIGHASH_NONE, the inputs are signed, but the sequence numbers are blanked, so others can create new versions of the transaction. However, the only output that is signed is the one at the s

	Description: (1) <dooglus> lost 1300 BTC

	23:38:37 (34725) <florence> no new name
	23:38:37 (20153) <unknown> flory. please don't gamble with any of doogs money, and if anyone here is up in investment consider donating to doog
	23:38:59 (2458) <usagi> I gave money away when I was up
	23:39:02 (34458) <florence> so doog did a charity, and let flory gamble with free 1300 btc
	23:39:03 (1601) <willphase> if flory pays it back then he's still up, and doog doesn't take a huge hit
	23:39:05 (34458) <florence> is that what happened today ?
