Title: Stealth address question Post by: christianlundkvist on July 01, 2014, 07:58:41 PM Hi all, I have a question about the general format of stealth addresses for anyone who has implemented them. In the Darkwallet Stealth wiki (https://wiki.unsystem.net/en/index.php/DarkWallet/Stealth) the address format is described as
Code: [version:1=0x2a] [options:1] [scan_pubkey:33] [N:1] [spend_pubkey_1:33] ... It seems to me that the options bitfield above is redundant. If options = 1 you are not using the spend_pubkey:s so they can be omitted in order to shorten your address. If options = 0 you need the spend_pubkey:s since you don't want to reuse the scan_pubkey for spends. It seems to me that instead of having the options bitfield you can just look at if N = 0 or not. Or is it more like this bitfield is reserved for other options that might be introduced in the future? /C |
