That means that it was a spam PM that got wiped before you read it.
143  Bitcoin / Alternative clients / Re: Time to move from Electrum on: January 08, 2018, 05:33:07 PM
Electrum is still one of my favorite wallets, but you have to understand its limitations:

 - Its privacy (and security, to some degree) is inherently bad due to its verification model.
 - It's written in an interpreted language, which makes me instantly suspicious of its security.
 - It has a very small team.

I'm OK with using Electrum for smallish amounts, with the assumption that all transactions/BTC in a single Electrum wallet can be trivially linked to each other.

IMO Electrum is still in the top two or three wallets. But although ThomasV is one of the best devs in Bitcoin, and some other wallet devs are also very good, this probably says more about how poor the wallet ecosystem is in general than how great Electrum is. Every wallet is seriously flawed in many ways.

I would accept your bid, but it's currently too low.

1@0.12  (if bitcoin forks are allowed)

I would allow Bitcoin forks in general, but I find it somewhat deceptive to name a fork or other altcoin "Bitcoin ____", since they are not Bitcoin. So I will not accept your bid in this case.

145  Bitcoin / Electrum / Re: Critical Security Release: Please update to Electrum 3.0.4 on: January 07, 2018, 10:26:41 AM
1) If I use a firewall to block incoming connections on all ports except ones that I allow and considering that fact that my ISP doesn't allow open ports (I can't open ports through my router, hence I can't even host anything through my public IP) then would it still be possible for an attacked to use javascript to find my JSONRPC port and then perform transactions?

That won't help.

2) If I have encrypted my electrum wallet using a password, then am I safe considering that the attacker cannot steal my funds, view my seed or export my private keys? (I'm sure other wallet settings could be changed though).

There is no known way for them to steal your BTC in that case, though they can see your addresses/transactions and change your settings. I'm not sure (and maybe nobody yet fully knows) exactly how much damage they can do by changing your settings. So you should absolutely still update.

WARNING: This key is not certified with a trusted signature!
gpg:          There is no indication that the signature belongs to the owner.
Primary key fingerprint: 6694 D8DE 7BE8 EE56 31BE  D950 2BD5 824B 7F94 70E6

That's normal, it means that his key isn't connected to your GPG trust graph. Typically you would --lsign-key the key after verifying it through some other method. PGP is kind of weird.
146  Bitcoin / Important Announcements / Critical Electrum vulnerability on: January 07, 2018, 03:34:59 AM
A vulnerability was found in the Electrum wallet software which potentially allows random websites to steal your wallet via JavaScript. The bug presumably also affects altcoin derivatives of Electrum such as Electron Cash. If you don't use Electrum or a derivative, then you are not affected and you can ignore this.

Action steps:

 1. If you are running Electrum, shut it down right this second.
 2. Upgrade to 3.0.5 (making sure to verify the PGP signature).

You don't necessarily need to rush to upgrade. In fact, in cases like this it can be prudent to wait a while just to make sure that everything is settled. The important thing is to not use the old versions. If you have an old version sitting somewhere not being used, then it is harmless as long as you do not forget to upgrade it before using it again later.

If at any point in the past you:

 - Had Electrum open with no wallet passphrase set; and,
 - Had a webpage open

Then it is possible that your wallet is already compromised. Particularly paranoid people might want to send all of the BTC in their old Electrum wallet to a newly-generated Electrum wallet. (Though probably if someone has your wallet, then they already would've stolen all of the BTC in it...)

This was just fixed hours ago. The Electrum developer (ThomasV on the forum, ecdsa on github) will presumably post more detailed info and instructions in the near future.

Update 1: If you had no wallet password set, then theft is trivial. If you had a somewhat-decent wallet password set, then it seems that an attacker could "only" get address/transaction info from your wallet and change your Electrum settings, the latter of which seems to me to have a high chance of being exploitable further. So if you had a wallet password set, you can reduce your panic by a few notches, but you should still treat this very seriously.

Update 2: Version 3.0.5 was just released, which further protects the component of Electrum which was previously vulnerable. It is not critically necessary to upgrade from 3.0.4 to 3.0.5, though upgrading would be a good idea. Also, I've heard some people saying that only versions 3.0.0-3.0.3 are affected, but this is absolutely wrong; all versions from 2.6 to 3.0.3 are affected by the vulnerability.

Update 3: You definitely should upgrade from 3.0.4 to 3.0.5, since 3.0.4 may still be vulnerable to some attacks.

Update 4: Here is the official, more complete response from the Electrum dev team.

Update 5: Apparently only a minority of Electrum users have upgraded, so I'll make the news item red again for a while. No significant facts have changed since yesterday, though.

I (still) wonder how Atlas is doing - hopefully well after all the drama from years ago.  I wonder if he held through all the ups and downs or if he went on to something else.  Must be in his 20s now.

I heard from him a year or two ago, and he was OK.

Although he did sometimes annoy me (especially that time he threatened to commit suicide and I had to contact his local police), I miss the pure passion that he and many others had at the time. It's become pretty diluted now.
148  Bitcoin / Electrum / Re: Electrum vulnerable to Meltdown and Spectre CPU attacks? on: January 06, 2018, 04:30:08 PM
There are basically three "levels" of the vulnerability:

"Meltdown": Caused by an embarrassing flaw in Intel CPUs which allows any code running on the computer (including JavaScript) to ignore memory protection fairly easily and access the entire contents of memory. The part of this where code can access all of physical memory is what's fixed by the various OS patches already out. The browser patches (which are mainly for spectre-1, see below) can also help against meltdown somewhat.

"Spectre-2": Caused by widespread flaws in our understanding of CPU design. Affects most CPUs, almost certainly including all modern AMD CPUs, though attacks against Intel CPUs may be easier simply because the internals of Intel CPUs are more well-understood. As with meltdown, it allows any code running on the computer (potentially including JavaScript) to access the entire contents of memory. However, this is much more difficult to pull off. It will probably be a while before we see practical attacks, and doing it via JavaScript increases the difficulty so much that we might never see JS-based attacks. Fixing the part of this where code can access all of physical memory requires an OS update (done on Windows, not done yet on Linux) and probably an update to CPU microcode, which may depending on the circumstances require an update to UEFI/BIOS and/or other firmware. Spectre-2 will become a bigger and bigger problem as the months go on and people increasingly figure out how to exploit it, since solving it can be difficult, especially on older devices.

"Spectre-1": Caused by widespread flaws in our understanding of CPU / software design. Affects all CPUs. It has two effects. First and most seriously, it allows sandboxed code running within a process (such as JavaScript running in a browser) to read the process's memory outside of the sandbox. Second, it introduces yet another arcane timing-like attack between processes running on the same hardware. This probably cannot be fixed by OS updates; security-sensitive programs will basically have to be redesigned with this attack in mind, probably with support from changes in compilers / programming languages. The various browser updates that have recently been released address the most obvious uses of spectre-1, but they are far from a complete solution. A lot more work will be required to make things reasonably secure, and then this will continue to haunt software development forever, especially for the type of sensitive software that today worries about timing attacks.

If you are successfully attacked by the full-memory variants, then it allows an attacker to do things like capture any encryption keys currently active (eg. disk encryption, wallet encryption, gpg-agent keys, etc.), get passwords currently in memory, get wallet keys currently in memory, get some/all of your browser cookies, etc. If you are successfully attacked by the single-process variant, then the attacker can only see the memory of that process, such as seeing the contents of all of your tabs for a browser.

Software like Electrum can't do anything about meltdown or spectre-2 other than avoiding keeping keys in memory as much as possible. For spectre-1, adjustments may be necessary, but for Python programs like Electrum it may mostly or entirely be done at a lower level.

For illustration of how widespread this problem is: I designed a full CPU from scratch as a project in a university course, and I'm pretty sure that my relatively primitive CPU was vulnerable to at least spectre-1, since it did the type of speculation which is causing problems here. This is a very deep problem.

150  Economy / Auctions / Advertise on this forum - Round 232 on: December 29, 2017, 06:44:07 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, 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, banks, or funds; 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 8 or 9 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:

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 0.02.
- The bidding starts at 0.02.
- 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.

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.

It seems that income skyrocketed in 2017, but mod payments did not keep up. My understanding is that mod payments should be 25% of income. What happened?

I posted an estimate like that a long time ago, but it was an estimate as of that time, not a guaranteed amount. The mod payments algorithm has never taken forum income into account whatsoever, and you can see that in 2015 and 2016 it was much higher than 25%.

The increased-value reserve and massive 2017 income (which may well have been just a weird temporary trend) came pretty suddenly. I'm not sure yet how best to handle it. I've been thinking of maybe allocating some of the money toward creating a registered non-profit which would have a similar mission as the forum, but would focus more on things like free-speech legal battles and the development of true decentralized forum software. I also need to figure out ways of delegating more, since I am absolutely swamped as things are right now. Perhaps I could hire someone with a business degree or something who can act more like a proper CEO. Suggestions publicly or via PM are welcome, but please focus more on structural improvements rather than lists of things to throw money at. This has already been the case to a large extent, but especially now, the limiting factor is mostly time/people/skill/trust rather than money.

I'm behind on the accounting. 2015 is basically done, but I need to double-check it and apply the results of taxes (even when there's a net loss, there may be capital gain taxes). 2016 is still very incomplete: I've had to do half of the work in order to pay taxes, but I basically need to go through everything again to figure out forum balances. Sloppy, I know, but I've been disincentivized to spend many hours figuring it out exactly because the reserves so obviously exceed the expenses. There's currently about 1250 BTC(+BCH) in reserve.

Keep in mind that if I make an accounting mistake, almost certainly the result of this will be that I pay forum expenses out of my own pocket accidentally. The income is almost all very obvious/public, and I have to list all of the expenses that I temporarily paid out of pocket in order to be repaid from the forum income or reserves. So it's very unlikely that I would take too much money.

Here are approximate numbers.

Code:
2015:
Income: About $144,000
Expenses - Forum software project: $849,400
Expenses - Mods and others: About $104,000

2016:
Income: About $178,000
Expenses - Forum software project: $36,260
Expenses - Mods and others: About $85,000
Expenses - Hosting etc: About $27,000

Income: About $1,065,000

155  Economy / Speculation / Re: Wall Observer BTC/USD - Bitcoin price movement tracking & discussion on: December 22, 2017, 08:41:37 AM
The rabbit from BTC's hat is coming (it's the lightning network). Meanwhile BCH has done exactly nothing to that effect. And no, just increasing the block size limit is not solution, just a patch in the gaping hole.

BCH is so boring technologically... ETH has better tech for cash-like transactions, with their effectively-unlimited block size, short block intervals, and uncle blocks, and ETH isn't even specifically designed for that. (Note: I have never owned any ETH.) People are going to claim that I'm saying this just because I have a personal grudge against BCH (which isn't really true), but I just can't take BCH seriously at all.
156  Economy / Speculation / Re: Wall Observer BTC/USD - Bitcoin price movement tracking & discussion on: December 22, 2017, 08:28:00 AM
I've been feeling that the price jump has been built on FOMO speculation for a while now. I think that the real, solid base is around $6k (roughly following the longer-term linear trend), but I expect speculators to stabilize it if it reaches $10k, at the very least, and then those prices might or might not stabilize.

So IMO $6k and below is "solid", $6k-$10k is semi-solid, and everything above $10k is a house of cards. No idea what'll actually happen in the next few days, though; it's pure speculative madness. In the next hour, I wouldn't be surprised to see a drop to $10k or an increase to $16k.
157  Bitcoin / Legal / Taxes on forks in the US on: December 21, 2017, 12:31:20 AM
I have not yet gotten this checked by an accountant. This is not legal/tax advice. But since I'm seeing all sorts of weird and almost-certainly-wrong theories, here is my interpretation of US tax law in relation to forks.

Imagine the following hypothetical:

 - Canada somehow gets access to a database of exactly how many US dollars each person owns, updated live.
 - At some exact instant in time, they take a snapshot of this database.
 - Anyone who has a balance in Canada's USD snapshot is automatically and involuntarily given a bank account in Canada containing an equal number of Canadian dollars. You can walk into a Canadian bank and withdraw the CAD, or sell it, or whatever.
 
Forks are like that, but since Bitcoin is decentralized, anyone can create one of these forks with no cost whatsoever. I could personally create a million such forks, and everyone who owns bitcoin would receive a million different currencies. You cannot avoid receiving the coins, it is done without your permission, and very often you will not even know that a fork had occurred. Furthermore, in many cases it would be unsafe to access the fork-coins due to the stupid ways in which forks are done. Due to all of these factors, I consider it impossible to account for forks at time-of-creation, and forks therefore cannot be treated as dividends or other income at time of creation.

Given that, the closest similar handling seems to be a stock spin-off. In a spin-off, you have to adjust the basis of the original asset according to the spin-off's value at time of creation. However, it is not always clear that anything is being taken from Bitcoin when these forks are created. Often, the Bitcoin price does not decrease upon the creation of one of these forks, but the fork sometimes still attains a somewhat-significant value. Some would argue that the money flowing into the fork-coin is being redirected from Bitcoin, and so the basis for the fork-coins should not be zero, but it is unclear. For example, here are the prices of Bitcoin and BCH near the creation of BCH on Aug 1, 2017:
Code:
  Date  BTC BCH
Jul 31 2796 N/A
Aug  1 2723 281
Aug  2 2759 366
Aug  3 2832 602
Aug  4 3140 377
Aug  5 3224 237

As you can see, although the BTC price dropped slightly on the day that BCH was created, BCH had a much higher value than the drop in BTC price would account for. You could theorize that the price of BTC would've been higher if the fork had not happened, but this is subjective and impossible to quantify.

An additional complication is that in a stock spin-off, there will be an official initial spin-off price based on trading on regulated futures markets and price as of market-start. But there are dozens of Bitcoin and other-cryptocurrency exchanges, none of which are "official". Forkcoins have no regulated futures markets (or regulated any markets in most cases). There is no single unambiguous starting price for the fork-coin. Trading is also 24/7 and continuous, not broken up into days. So you can't get a good initial price for forks.

Plus, if forkcoins are treated as spin-offs with non-zero value, then the following scheme seems possible:

 - Some tiny fork-coin is created, and it attains an "initial market price" of $1 on absolutely minuscule volume. In other words, although the charts show it as having a price of $1, anyone who cared to do so could bring it down to nearly nothing with just a bit of money.
 - Using spin-off basis calculations, all Bitcoin holders can now reduce the basis of their bitcoins slightly by treating the above tiny fork-coin as a spin-off, even if that fork-coin very soon disappears to basically nothing.
 - Repeat hundreds of times, reducing everyone's Bitcoin basis significantly.
 
With all of the above in consideration, my conclusions are:

 - Forkcoins are not adequately handled by current US tax law.
 - The most justifiable thing to do right now, which avoids as many of the above issues as possible, is to handle it as a capital gain at the time of sale with a basis of zero and an acquisition date of the fork time. I do not think that it is necessarily fair for BTC holders to have to use a basis of zero here, but anything else seems too difficult to calculate/justify.
 
Again, this is only my interpretation based on my own research, and it is not tax advice. Consult an accountant.

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 0.02.
- The bidding starts at 0.1.
- 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.

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.
