541  Other / Meta / Re: Use of TOR Browser for Bitcointalk on: November 24, 2019, 08:09:22 PM

You -> VPN -> Dest is often better than nothing, but definitely can't be relied upon if you need actual anonymity. The VPN can see everything you do, the destinations can see that you always come from the same VPN, and you're probably leaving tons of other traces because you're not using Tor Browser. Note that this might in some cases be worse than nothing if you trust your VPN less than your ISP; for example, IMO Cloudflare's VPN is more likely to have its traffic analyzed en masse by the NSA than your native ISP's traffic.

You -> Tor -> Dest is better than just a VPN, but there are many known attacks which can be used against Tor, plus possible 0-days against the browser, so you can never feel 100% anonymous. Also, even if you treat Tor as perfect, it's really difficult to remain consistently anonymous; for example, you might via Tor use the same email address to order something shipped to you as you use to speak out against your oppressive government, and that's a link that can be exploited. Even though Tor is pretty flawed, being far behind state-of-the-art research, it's these non-Tor anonymity failures which almost always get people. This was the case for Ross Ulbricht, for example. As I always say: if you think that you're perfectly anonymous, then you're wrong. Think of even the best anonymity tech as a light bulletproof vest which will increase your survivability a bit, not as an impenetrable wall.

You -> VPN -> Tor -> Dest protects against certain attacks where Tor nodes are considered evil, but can totally screw you if your VPN is evil. It might make sense if you trust your VPN more than a random Tor node. The VPN acts similar to a Tor guard node in this case. In fact, it'd be most efficient if the VPN actually allowed you to use it as a fixed Tor guard node so that you don't have a useless extra node in the Tor circuit, but nobody does this.

You -> Tor -> VPN -> Dest is much worse than Tor alone because the VPN can link all of your traffic together, whereas with Tor you change your exit node constantly. (It's also difficult to actually accomplish because VPN software isn't usually set up to support this, and VPNs are often- & best-done over UDP, which Tor doesn't support.) What would be useful would be if you could pay via blinded bearer certificates for access to a whole constellation of exclusive paying-only Tor exit nodes, but nobody does this, either... Anonymity research is pretty immature, but actually-implemented anonymity tech is far behind even what is known to be possible.

IIRC, US has x4 the military manpower [apart from other military technologies] of Iran but a war between these two is going to be ugly for both.

Currently, the US population doesn't care about Iran one way or the other. The average American wouldn't be able to find Iran on a map, and most think due to the similar name that it's basically like Iraq. They're OK with attacks against Iran that don't have immediate consequences for the US. But once American soldiers start dying and/or military costs become truly ridiculous, the US population will demand an end to the war. Certainly the US wouldn't be able to draft its population to fight in Iran.

If a military objective can be accomplished in weeks, then the US could do it, since that'll be over before the American population notices. If a lot of Americans die, though, there will be significant political fallout for whoever orders the attack.

The only way a multi-year campaign could be done is if Iran perpetrates an attack against the US similar to Pearl Harbor (or if the US population is led to believe this). In this case, the US could conquer some territory, but it still doesn't have enough resources to take and hold large sections of Iran. And after a few years, the costs in lives and materials would pile up to the point where it'd lose any public support that it once had.

A US vs Iran war would be like Vietnam, but much worse for the US because Iran is a much stronger target. If the US's goal is to destroy a few cities or assassinate a few specific targets, it can definitely be done, but the US cannot conquer Iran without a lot of support from either allied countries or a substantial percentage of the Iranian population.

With Mozilla & Google now moving toward DNS over HTTPS, they could switch to a non-ICANN root zone, though that'd be pretty messy, sort of like a contentious hardfork of the DNS. I wonder if they've considered this, though.

I doubt that the .org registry will actually change anything except increasing prices.
544  Other / Meta / Re: 10th anniversary art contest on: November 22, 2019, 09:37:48 PM
Thanks to everyone who submitted art! I was blown away by both the number of submissions and the number of really good submissions!

I'm not sure that I'll be able to decide on winners today as I'd planned, though I'll try to do it within days. I want to carefully review about 300 of the best submissions. My current expectation is that as many as 100 people will receive some BTC, but a few will receive much more than the others.

For the badges, I think that I'm going to collect the top ~50 most-merited submissions and let the community vote on the winners from among them. But I'm not going to think much about the exact framework of this until I've determined the BTC winners.

Thanks again!
545  Other / Meta / The Bitcoin Forum is 10 years old! on: November 22, 2019, 06:04:28 PM
The Bitcoin Forum is 10 years old today! The forum, originally a part of bitcoin.org, was created by Satoshi and Sirius in 2009, Bitcoin's infancy. In the first few years, the Bitcoin community was both incredibly small and concentrated almost entirely to this forum; by the end of 2010, there were only 995 users with any posts, and this was the Bitcoin ecosystem. I have fond memories of reading every single post anyone made in these early days: IIRC, it was only sometime in 2011 when I was forced to give this up due to the volume of posts. Over the course of 10 years, Bitcoin exploded, altcoins appeared, the community expanded beyond just this forum to a large degree, and an awful lot happened here on the forum. But we're still operated with much the same moderation philosophy as our first admins Satoshi and Sirius 10 years ago: create a "territory of freedom", and let humanity happen.

I'm honored to be your head administrator, but I'm only a tiny part of the forum. The forum is and has been a collaboration between thousands of people, including:
 - Posters, who make the forum a forum
 - Reporters, merit-givers, and scam-fighters, who make the forum (somewhat) sane
 - Moderators and admins of the past & present, who keep things running smoothly
 - Donors, sponsors, and advertisers of the past & present, who fund our operations
 
Thank you, everyone, for your continuing contributions to this legendary forum! Let's try to somehow make the next 10 years even more interesting than the last.



Also check out:
 - The community-generated list of notable posts over the forum's 10 years.
 - The 10th anniversary art contest, which received many incredible submissions. LoyceV created a page with the top-merited submissions. Thanks to everyone who participated! I'll create a separate post collecting the winning submissions once that's all figured out.
 - dannybrown's Bitcointalk game, an awesome interactive submission to the art contest.
 - 10th anniversary Coldkey.

@theymos What is Respect BTW  Huh

It was an SMF mod used here for only a short time as an experiment. IIRC, you could upvote/downvote users, but there were no effective limits/controls, so it was kind of meaningless.
547  Other / Meta / Re: Merit spree is underway. on: November 22, 2019, 05:54:12 PM
For anyone doing analysis: When someone makes multiple submissions, I consider the merit I've already given them when deciding how much merit to give later submissions. So if someone posts two submissions to which I'd normally give 50 merit, the second one will get less. Therefore, it'd be most accurate to consider my merit awards in terms of total per-person rather than per-submission.
548  Other / Meta / Re: [BCT FACT] Bitcointalk was originally on Bitcoin.org but ... drama on: November 22, 2019, 05:42:37 PM
Do we have any archive or something of the forum when it was running as bitcoin.org/smf/ or forums.bitcoin.org?

You're on it. Nothing was changed except the URL/domain.
549  Other / Meta / Re: [BCT FACT] Bitcointalk was originally on Bitcoin.org but ... drama on: November 22, 2019, 02:24:01 PM
Smiley That makes me nostalgic for when I was quite that naïvely revolutionary. The forum was pretty crazy back then...

What an awesome thread!  You guys have a ton of great ideas.  Has anyone seen Silk Road yet?  It's kind of like an anonymous amazon.com.  I don't think they have heroin on there, but they are selling other stuff.  They basically use bitcoin and tor to broker anonymous transactions.  It's at http://tydgccykixpbu6uz.onion.  Those not familiar with Tor can go to silkroad420.wordpress.com for instructions on how to access the .onion site.

This has big publicity potential and could increase the user base. It's just a bit difficult for them to build reputation as most people don't want to publicly admit they bought from there. Maybe private recommendations will do. Or people can say "I know somebody who successfully bought from them".

Or was jgarzik the one to suggest that domain?

He came up with it.

552  Economy / Auctions / Advertise on this forum - Round 292 on: November 20, 2019, 06:45:37 PM
The forum sells ad space in the area beneath the first post of every topic page. This income is used primarily to cover hosting costs and to pay moderators for their work (there are many moderators, so each moderator gets only a small amount -- moderators should be seen as volunteers, not employees). Any leftover amount is typically either saved for future expenses or otherwise reinvested into the forum or the ecosystem.

Ads are allowed to contain any non-annoying HTML/CSS style. No images, JavaScript, custom fonts, or animation. Ads must appear 3 or fewer lines tall in my browser (Firefox, 900px wide). Ad text may not contain lies, misrepresentation, or inappropriate language. Ads may not link directly to any NSFW page. No ICOs[1], loggable mixers[2], banks, funds, or anything that a person can be said to "invest" in; I may very rarely make exceptions if you convince me that you are ultra legit, but don't count on it. Ads may be rejected for other reasons, and I may remove ads even after they are accepted.

There are 10 total ad slots which are randomly rotated. So one ad slot has a one in ten chance of appearing. Nine of the slots are for sale here. Ads appear only on topic pages with more than one post, and only for people using the default theme.

Duration

- Your ads are guaranteed to be up for at least 7 days.
- I usually try to keep ads up for no more than 11 days.
- Sometimes ads might be up for longer, but hopefully no longer than 12 days. Even if past rounds sometimes lasted for long periods of time, you should not rely on this for your ads.

Stats

Exact historical impression counts per slot:
https://bitcointalk.org/adrotate.php?adstats

Info about the current ad slots:
https://bitcointalk.org/adrotate.php?adinfo

Ad blocking

Hero/Legendary members, Donators, VIPs, and moderators have the ability to disable ads. I don't expect many people to use this option. These people don't increase the impression stats for your ads.

I try to bypass Adblock Plus filters as much as possible, though this is not guaranteed. It is difficult or impossible for ABP filters to block the ad space itself without blocking posts. However, filters can match against the URLs in your links, your CSS classes and style attributes, and the HTML structure of your ads.

To prevent matches against URLs: I have some JavaScript which fixes links blocked by ABP. You must tell me if you want this for your ads. When someone with ABP and JavaScript enabled views your ads, your links are changed to a special randomized bitcointalk.org URL which redirects to your site when visited. People without ABP are unaffected, even if they don't have JavaScript enabled. The downsides are:
- ABP users will see the redirection link when they hover over the link, even if they disable ABP for the forum.
- Getting referral stats might become even more difficult.
- Some users might get a warning when redirecting from https to http.

To prevent matching on CSS classes/styles: Don't use inline CSS. I can give your ad a CSS class that is randomized on each pageload, but you must request this.

To prevent matching against your HTML structure: Use only one <a> and no other tags if possible. If your ads get blocked because of matching done on something inside of your ad, you are responsible for noticing this and giving me new ad HTML.

Designing ads

Make sure that your ads look good when you download and edit this test page:
https://bitcointalk.org/ad_test.html
Also read the comments in that file.

Images are not allowed no matter how they are created (CSS, SVG, or data URI). Occasionally I will make an exception for small logos and such, but you must get pre-approval from me first.

The maximum size of any one ad is 51200 bytes.

I will send you more detailed styling rules if you win slots in this auction (or upon request).

Auction rules

You must be at least a Jr Member to bid. If you are not a Jr Member and you really want to bid, you should PM me first. Tell me in the PM what you're going to advertise. You might be required to pay some amount in advance. Everyone else: Please quickly PM newbies who try to bid here to warn them against impersonation scammers.

If you have never purchased forum ad space before, and it is not blatantly obvious what you're going to advertise, say what you're going to advertise in your first bid, or tell me in a PM.

Post your bids in this thread. Prices must be stated in BTC per slot. You must state the maximum number of slots you want. When the auction ends, the highest bidders will have their slots filled until all nine slots are filled.

So if someone bids for 9 slots @ 5 BTC and this is the highest bid, then he'll get all 9 slots. If the two highest bids are 9 slots @ 4 BTC and 1 slot @ 5 BTC, then the first person will get 8 slots and the second person will get 1 slot.

The notation "2 @ 5" means 2 slots for 5 BTC each. Not 2 slots for 5 BTC total.

- When you post a bid, the bids in your previous posts are considered to be automatically canceled. You can put multiple bids in one post, however.
- All bid prices must be evenly divisible by 0.01.
- The bidding starts at 0.01.
- I will end the auction at an arbitrary time. Unless I say otherwise, I typically try to end auctions within a few days of 10 days from the time of this post, but unexpected circumstances may sometimes force me to end the auction anytime between 4 and 22 days from the start. I have a small bias toward ending auctions on Fridays, Sundays, and Mondays.
- If two people bid at the same price, the person who bid first will have his slots filled first.
- Bids are considered invalid and will be ignored if they do not specify both a price and a max quantity, or if they could not possibly win any slots

If these rules are confusing, look at some of the past forum ad auctions to see how it's done.

I reserve the right to reject bids, even days after the bid is made.

Price flattening

At the end of the auction, after the winning bids are all determined, I will do a "price flattening" operation. This has no effect on which bids actually win. For each bid, in order of lowest to greatest price/slot, I will reduce each bid's price/slot to the highest value which is equal to or only the minimum increment greater than the next-lower bid. This allows you to bid higher prices without worrying so much, but you still mustn't bid more than you're willing to pay. Example:

Code:
This:
Slots  BTC/Slot  Person
    6      0.20       A
    1      0.16       B
    1      0.08       C
    1      0.08       D

Becomes:
Slots  BTC/Slot  Person
    6      0.10       A [step 4: reduced to 0.09+0.01=0.10]
    1      0.09       B [step 3: reduced to 0.08+0.01=0.09]
    1      0.08       C [step 2: same as the next-lowest, unchanged]
    1      0.08       D [step 1: the lowest bid is always unchanged]

Payment, etc.

You must pay for your slots within 24 hours of receiving the payment address. Otherwise your slots may be sold to someone else, and I might even give you a negative trust rating. I will send you the payment information via forum PM from this account ("theymos", user ID 35) after announcing the auction results in this thread. You might receive false payment information from scammers pretending to be me. They might even have somewhat similar usernames. Be careful.

[1]: For the purposes of forum ads, an ICO is any token, altcoin, or other altcoin-like thing which meets any of the following criteria: it is primarily run/backed by a company; it is substantially, fundamentally centralized in either operation or coin distribution; or it is not yet possible for two unprivileged users of the system to send coins directly to each other in a P2P way. The intention here is to allow community efforts to advertise things like Litecoin, but not to allow ICO funding, even when the ICO is disguised in various ways.
[2]: A loggable mixer is a service marketed primarily for improving transaction privacy which accepts full custody of cryptocurrency for a time and has the technical ability to log where the cryptocurrency comes from and goes to (even if they promise not to log).

I expect this auction to end between Monday and Wednesday next week.

Relating to Mimblewimble and Grin, I’ve come across a couple of recent interesting reads, fresh from the oven:

https://medium.com/dragonfly-research/breaking-mimblewimble-privacy-model-84bcd67bfe52
https://medium.com/grin-mimblewimble/factual-inaccuracies-of-breaking-mimblewimbles-privacy-model-8063371839b9 (counters arguments to the former link).

I don’t really know how much certainty the above articles provide, but it casts some doubt as to exactly how far the anonymity goes. At least if it’s what I was after, I’d keep reading these sort of articles for a few days to get a better idea of the extent.

AFAIK, that medium post is nothing new.

Base mimblewimble isn't really designed to be a "black box of reliable anonymity" in the way that Monero or Wasabi-CoinJoins are, where connections are hard-broken. It's more of a framework on which you could build solid anonymity using techniques that have largely not yet been perfected, plus major scaling benefits. Monero = CT + stealth addresses + ring signatures. Grin = CT + "stealth addresses" + mimblewimble. Because grin replaces ring signatures with mimblewimble, its privacy is less reliable than Monero's. Probably the grin developers have tried to make their mimblewimble transaction aggregation methods good, but I currently wouldn't put much faith in it, and IMO it'll take many years of research to get something really solid. That said, CT + stealth addresses offer a certain base level of privacy, and grin's method of handling stealth addresses (using an interactive protocol, exchanging "slates") is both more scalable than Monero and probably more private.

If your goal is to mix coins, grin is definitely not for you right now, and it may never be. Monero's goal is maximal privacy, regardless of the cost. Grin's goal is excellent privacy, consistent with scaling.

Merit sources are free to reveal their source amounts, though I think it may be a bit unwise. While it will eventually become obvious roughly what the source amounts are from the stats, there's a huge difference between showing up in a "list of probable merit sources" and having a quote out there of you basically saying "I'm a merit source, come beg me for merit, complain about every merit I send, and accuse me of being part of the anti-X/pro-Y conspiracy."
558  Other / Politics & Society / Re: People are burning the banks in Iran right now on: November 18, 2019, 09:30:21 PM
I mean I think the Iranians are stuck b/w a rock and a hard place here. They've already worked with the US on the first iteration of the Iranian deal, and they gave up all of their enriched uranium -- what they got out of it was sanction relief -- but now they got fucked, cause now they don't have any enriched uranium to use as part of their negotiations with the US to get a better deal, and their economy is under constant pressure from the sanctions.

The only thing they can do to stop this is to renegotiate the Uranium deal with the US, unless they enrich uranium again to the 2011?Huh levels to get a better deal.

Iran probably does not have a path forward, unless they fall to the US or continue to enrich uranium and pray that the US doesn't make their sanctions worse -- as they may lose the public support battle.

Agreed. Trump clearly got out of the deal almost entirely for political reasons, and he'd probably accept even a slightly better deal. But if Iran went along with this -- allowing a counterparty to break a deal on a whim -- it'd make them look really weak. Meanwhile, there's nothing really pressing the US to back down.

I suppose that Iran's strategy is to pick at the US and its allies with small strikes, but make it small-scale/ambiguous enough, and set things up politically (eg. pointing to the broken nuclear deal) that the US couldn't rely on many allies if it wanted to invade Iran fully. The US doesn't have the political will to sustain a real war against Iran for long. The US could do a lot of airstrikes etc., though, and I'm not convinced that small strikes by Iran will ever get them anywhere.

Authoritian, yes. Socialist, no. Typical American here thinks socialism=communism=dictatorship.

No, what I mean by "socialism" is "a lot of central economic planning and redistribution": pretty far left on the 2-axis political compass. I'm aware of Marx's definition, but that's not really what people tend to mean nowadays. Words change, especially in politics; for example, leftists stole "liberal" from libertarians, and we stole "libertarian" from them (at least in the US).
