Stealth Transfers - HOW TO

[bytemaster]

Is it possible to place stealth bid/ask orders on the DEX? If not, what portion of balances become declared when an order is placed by the receiver of a stealth transfer?

Nope.   The best you can do is this:

1. Transfer From Blind to temp-account
2. Register new Account with temp-account
3. Transfer From Blind to new account
4.  Place orders from new account that isn't tied to any other account.

Why is 3) needed when it's public info which account registered new-account ? (i.e, why not fund new-account from the stealth funds sent to temp-account on step 1))

"temp-account" is a special account built into the blockchain that EVERYONE has permissions on, but whose balance must always be 0 at the end of every transaction.

Steps 1 and 2 must be in the same transaction.

@bytemaster, if you want, you can have write access to docs.bitshares.eu. It uses restructure text (similar to markdown).
If you don't want to waste time for that, would it be ok for you that I copy&paste (reformat) your howtos over there?

Copy and paste at will!

Much needed info, thanks BM!

really nice. bts2 is gearing up for the real-world txs.

That transaction was going from BLIND to PUBLIC... so not particularly interesting

The GUI doesn't know how to represent the blind operations at the moment.

I found some null transactions with 15 fees on the blockchain. (e.g. #177905). It was obviously stealth transfer test

Those of you who wish to keep your balances and transfers private and have the ability to use the CLI wallet:

Have Fun!
