Title: Stealth addresses? Post by: testconpastas2 on May 03, 2014, 04:22:09 PM Now, the pretty cool darkwallet has just been released.
Are stealth addresses going to be included in our favorite wallet any time soon? Regards. Title: Re: Stealth addresses? Post by: Abdussamad on May 04, 2014, 05:02:08 AM You can see the roadmap here:
https://bitcointalk.org/index.php?topic=427617.0 Stealth addresses are not on the roadmap. AFAIK the stealth address specs haven't been finalized yet and that is stopping people from implementing them. This is a long journey. BIP38, multisig etc. have still not gotten widespread support after many years. HD wallets are just beginning to come out. Title: Re: Stealth addresses?

Thank you. sorry to hear it :( multisign and stealh addr, are IMHO two of the most important security features since BIP38 and HD wallets. Title: Re: Stealth addresses?

Stealth Addresses would be difficult at this stage to implement, as the implementation of DW is not finalized and has yet to be accepted as a standard format. Until Stealth Addresses as they exist in Dark Wallet, are accepted as a BIP, I wouldn't think taking the time to include them would be worth it. (someone correct me if I'm wrong) However, I think one problem of the current implementation of stealth addresses in DW is the way they handle multisig P2SH. The stealth address would have to include the spend_pubkey of each of N addresses in it, so as you extrapolate it to 5 of 9, 17 of 33 etc etc... the stealth address will be unwieldy large. I think if they would just keep the format as strictly P2KH... Not to mention that implementing Stealth Addresses as they exist in DW would require storing a separate table on the Electrum servers to look up for the OP_RETURNS in order to create the addresses. (otherwise they would not be able to be restored by seed) tl;dr: It's not finalized on their end, and until a BIP is approved for the "Dual-key Stealth Address which includes P2SH ability" it should not be included anywhere else but Dark Wallet. Edit: Links for further study. (#1 and #2 are revolutionary and make stealth usable to normal people. #3 is a little ambitious but I would like to see it happen) 1. Database format for OP_RETURN storage and easy lookup. https://wiki.unsystem.net/index.php/DarkWallet/Stealth#Database_file_format 2.

Post by: dabura667 on May 13, 2014, 11:46:53 AM I just got sending to stealth addresses working on 1.9.8... but to be honest, DW is talking about changing format, and I don't have the time to put in all the checks necessary to make it solid.
Not to mention the current master head on github did a complete overhaul of the Transactions class, which is what I did heavy work on... My opinion is: wait for it. It'll come eventually once stealth addresses are set in stone (in a BIP) Title: Re: Stealth addresses?
