Title: Will the Stealth BIP (Bitcoin Improvement Proposal) ever be done? Post by: ABISprotocol on June 08, 2015, 12:26:54 AM It seems like there have been endless delays and what appear to be "development arguments" which have hindered what could have been, by now, development of Stealth, or more precisely, the Stealth BIP (BIP number 63).
You can see a recent remark of mine on this subject in the Bitcoin repository here in which I linked to a twitter thread where developers discussed this issue: https://github.com/bitcoin/bitcoin/issues/5783#issuecomment-109680602 Indeed, here in the Electrum repository, on Jan. 11, 2015, dabura667 remarked, "Will re-open once Stealth is settled on. It keeps having "its the last change" over and over again... so I'll wait til it is a BIP. I will keep my branch up to date with the latest Dark Wallet version in case someone wants to use the commits." https://github.com/spesmilo/electrum/pull/817#issuecomment-69489090 On the other hand, nothing is keeping someone from actually writing the BIP, as it seems like "all they would need to do" is communicate with Peter Todd and Greg Maxwell to ask if they could actually write it up as per the procedure at bitcoin/bips: https://github.com/bitcoin/bips Here's the archived proposal from Peter Todd for Stealth Addresses, with acknowledgments: http://sourceforge.net/p/bitcoin/mailman/message/31813471/ Since it's already been assigned a number, why not just have it now published to github at bitcoin/bips and move ahead, and the other technical issues could be worked on further at the draft stage. It seems logical to see it move forward at this time. Please feel free to tell me here why it should not be published at this time or why I am a blithering idiot. :-) Respectfully, -ABISprotocol Title: Re: Will the Stealth BIP (Bitcoin Improvement Proposal) ever be done?

Is is a modification to make bitcoins more anonymous? That is what it sounds like to me but I am not sure. As I understand it in a basic way, the Stealth Address will help mitigate the problem of address reuse, though this may be an oversimplification of what it does. (One socially meaningful function that people could really appreciate right away is that stealth addresses would likely make a straightforward and guilt-free way for a organization (non-profit for example) to post such an address to receive donations, as they would not then be revealing a bunch of information about the donors [and others in the network] every time someone donates to the organization.) Why should you care? Essentially it's from a privacy angle, as that address reuse is done then this conveys information about you and others in the network. One could measure the extent to which you may be compromising privacy of others in the network based on your actions but without getting into that here, suffice it to say, address reuse isn't that great for the privacy of the network, and if wallets had support for stealth addresses, and if people had the ability to choose to use stealth or not to use it, depending upon their preferences of course, then that would be a good thing. It's actually not what I would call "anonymity" because the use of Stealth as described wouldn't result in anonymity per se (IMHO). I believe it would actually result in enhanced privacy. From the original paper by Peter Todd, "The txin's owned by the payor are not revealed to the payee. In fact, they could be held by a third-party who simply makes a transaction with the appropriate txouts on behalf of the payee. (...) Less information about the txouts is leaked." I don't consider such developments anonymous actually, but it's a pretty good privacy scheme. Here's what I believe to be the first ever successful stealth transaction: https://blockchain.info/tx/63e75e43de21b73d7eb0220ce44dcfa5fc7717a8decebb254b31ef13047fa518 Notice that there are things you can see about it. It's certainly not fully anonymous, from my perspective. OK, the final part of your question was, BIP. What is the stealth BIP? That's the Bitcoin Improvement Proposal. Stealth has been suggested to be made as a Bitcoin Improvement Proposal so that this would have support in bitcoin / core. The process lays out ideas that would help improvements happen and the developers vet them.

Could the reason be, that 3rd party mixers and built in mixer features within wallet providers void the need for such upgrades?

For example, in Electrum, you give someone your master public key so they can pay you, creating a brand new, 1-time only address, which vastly improves anonymity. Of course this Stealh address things seems more convenient than giving away a master public key, but seems to me the result is similar.

Lots of great benefits for improving once privacy. Title: Re: Will the Stealth BIP (Bitcoin Improvement Proposal) ever be done?

I am ALL for more privacy and would welcome ANY methods to achieve these goals. {Why do the government or a stalker need to know, how I spend my money?} Thanks for posting this. ;D The short answer is no, 3rd party mixers (such as a mixer plugin which presents bitcoin mixing as a feature, and could be "dropped into" Electrum because the feature provided is not mainline in Electrum, as example) don't provide a better level of privacy than what could be provided if stealth address were to be directly supported in the protocol. Here I am suggesting that this stealth BIP (BIP 63) be started, it all starts in the draft stage. There are different kinds of BIPs. Standards Track BIPs - Changes to the network protocol, block or transaction validation, or anything affecting interoperability. Informational BIPs - Design issues, general guidelines. This type of BIP is NOT for proposing new features and do not represent community consensus Process BIPs - Describes or proposes a change in process. Similar to Standards BIPs but apply outside the Bitcoin protocol. I don't know what kind of BIP this would end up being, but I am kind of assuming it might end up being a Process BIP, but again, I don't really know. I'm assuming that how it would be tracked and categorized would depend on Greg Maxwell and Peter Todd assuming this moves forward...

Peter, If you publish here a bitcoin address that is specific to funding the stealth BIP (# 63 as currently shown at https://github.com/bitcoin/bips) then I, and others here who support that, will publish that address and I suspect, that you will receive funds at that address, as people will be happy to donate (I certainly will contribute to it.) The effect of this will be amplified if you mention it on one of your social feed (twitter or wherever else). -ABISprotocol Edit: There are at least a few other people so far who have said in this discussion thread that they'd donate as well - you can see their comments here: https://bitcointalk.org/index.php?topic=1083961.msg11572012#msg11572012 Title: Re: Will the Stealth BIP (Bitcoin Improvement Proposal) ever be done?

What needs to be done, if I'm hearing this correctly from Peter Todd's perspective, is get him some financial (bitcoin) support for stealth BIP (63) in order for something to be done on it.

I was comparing xpub keys and stealth keys when you make either type publicly available, there's a reason to do that for some use cases (e.g. accountability for a charity) and in others to use stealth keys (I don't like that term for them really, doesn't really explain what they do too well). It would be nice if the privacy was better by default, it seems we could get some of the way there on the proposed confidential chain.

(.NET library for Bitcoin dev) For what I have seen, the BIP is just a formalization on paper of what already exist, I'm not sure this BIP is essential at all, just a nice to have. Isn't a written formalization probably always just "nice to have"? A specification for BIP 63 could serve as starting point for alternative implementations. But FWIW, since it wasn't mentioned before in this thread: https://wiki.unsystem.net/en/index.php/DarkWallet/Stealth What are your thoughts on why no-one has yet written this up into BIP 63 (though Peter Todd has recently made clear on bitcoin-development mailing list he has no intention of doing it, but indicated someone else should feel free to)? Again, as per part of my original post, this is one of the reasons that the Electrum wallet developer(s) gave for not finalizing the process of inclusion of stealth address into the wallet - they said they are waiting for BIP 63 to be published (presumably in draft is all it would take).

Well, if it blocks adoption, in this case it should be finalized. Genjix started working on that on https://github.com/genjix/bips/blob/master/bip-stealth.mediawiki (https://github.com/genjix/bips/blob/master/bip-stealth.mediawiki)Genjix, how can we help pushing BIP63 on what you have done ?

I agree that Amir would be the second most appropriate person to pick up on Todd's contribution as Peter has more important priorities now. He has been scarcely heard of lately however. If someone can get ahold of him and see if he has the time I will do my part to help donate money and organize a campaign to fundraise a salary to cover BIP63 being formalized and than tested.

Friendly bump? Suggest that someone connect with evoskuil due to that he has indicated in the recent past that he has BIP 63 on his todo list -- his PGP details are at https://github.com/evoskuil Title: Re: Will the Stealth BIP (Bitcoin Improvement Proposal) ever be done? Post by: Jet Cash on February 18, 2016, 05:38:24 AM The timing of anything to do with Bitcoin that includes the word "stealth", seems most unfortunate at the moment.

Post by: ABISprotocol on February 18, 2016, 07:02:39 AM The timing of anything to do with Bitcoin that includes the word "stealth", seems most unfortunate at the moment. When has it ever been fortunate or convenient? Two words. NEH (&) VAH This is why those who actually do anything about it should be supported. Meanwhile if someone would like to contact evoskuil (see my above comment) on this, that would be great. Thank you. Title: Re: Will the Stealth BIP (Bitcoin Improvement Proposal) ever be done?

I should get a new name. People don't seem to respond well to this one. :-\ Title: Re: Will the Stealth BIP (Bitcoin Improvement Proposal) ever be done? Post by: ABISprotocol on February 22, 2016, 02:17:28 AM So ABISprotocol is the new name for DeathNTaxes. I don't know who DeathNTaxes is (if that is, or was, actually a bitcointalk user). I'm not here all the time. If it was, I'm not the reincarnation of whoever that was. The emphasis of my posts (in the latter part of this thread) is that there is a simple process that you can go through if you (a) have an inquiry about BIP 63 status or when it might be written, or (b) want to contribute (though I think the funds available for it are ample if I'm not mistaken) either way, then.. Just contact evoskuil (the evoskuil on github) as I mentioned in my prior comment. It's not hard. His PGP is shown on his Github page. In case reminder is needed for why evoskuil is the right person to contact, please see: https://github.com/bitcoin-dot-org/bitcoin.org/pull/1129#issuecomment-155680014 A preliminary version of BIP 63 is here: https://github.com/genjix/bips/blob/master/bip-stealth.mediawiki More historical details can be seen earlier in the thread.
