ahhhhh, well that explains it.

I assumed (incorrectly) that listenonion=1 was intended to only make outgoing connections (which is how I experience that parameter on my setup). So incoming connections should work using listenonion/ephemeral hs addresses.

This is a problem with the concept of money itself; it's too sophisticated for most people to understand. That's why money systems are so easily used to trick people; it's easy to fool someone when they're trading with something if they don't understand why it's valuable.

So, you can tell the average person that platinum (or bitcoins) are better money instruments as much as you like, it can be explained very quickly in just 1 or 2 sentences. They still won't bite, it's too sophisticated a concept, they won't get it. Precious metals advocates know this, and so they can tell a much simpler story about gold that doesn't involve monetary theory, and still succeed selling gold to people that don't get or don't care about what gives money value.
1763  Other / Ivory Tower / Re: Donald Trump has been ordered not to meet Nigel Farage. on: August 21, 2018, 11:23:01 AM
As much as I support Trump I am hoping our next president is less polarizing. 

The choices tend to unpack like this (although there isn't always the same range available every election):


1. "Centrist", where powerful people just do what they want, but tell careful lies to soften the public reaction. Electorate get nothing, but hopefully stability maintains. Left or right administrations take turns to steer the country in what is essentially the same direction, the political class's direction.

2. "Populist", where slightly crazy politicians claim to sweep away all the BS of the political class, but then the political classes in other countries get in their way. Chaos ensues, then the electorate are convinced by the corrupt media to go back to the political class "centrism".


To me, this is a great way to keep the electorate in the political class's game. "Centrism" basically means "do what we say, and believe our lies, as you won't like what happens when a populist ruler gives you what you think you want".

Democracy is supposed to mean "rule by the masses", but it's just turned into a game where the politicians trick citizens into agreeing to give them all the power. The real answer is to stop looking to government to uphold our rights, as they will only give us the rights that don't interfere with the political class having more rights then we do. If we all start to behave like we have the same rights that governments and corporations do, and we use tools (like Bitcoin) to uphold those rights in a way that cannot be violated, then we will have real democracy.

I'm sorry, I'm not being clear.

Do we know why a static hidden service is needed?
It's not needed, but it's often desirable to have nodes with a static .onion address, eg as fallback nodes.

So, what I mean is: why is it needed to use a static hs address in order to accept incoming connections over tor? If the bitcoin client can create a new hidden service dynamically every startup, surely it's possible for the tor client to forward the dynamically created address to the tor network in the same way as it does for a static address, along with the port number it's using? It seems like it's just a limitation of the way hidden services function, but is that something that could be added to the hidden service design in future, or is it inherently impossible?


It would be so much better if port forwarding worked using a dynamic hidden service addresses (i.e. with listenonion=1), for both ease of use and anonymity reasons. A fundamental limitation of Tor hidden services?
Huh? It's not supposed to work. By default, public IP discovery is disabled when using Tor, for anonymity, so forwarding port 8333 is useless (doubly so if you bind to 127.0.0.1 instead of the address you forwarded the port to). If you want to be able to receive incoming connections over both Tor and clearnet (anonymity be damned), additional configuration is required. I'm not sure what you're trying to accomplish.

As above, I can't see a reason why the tor client cannot be designed to function in a way that helps p2p software accept incoming connections and have the anonymity of using throwaway hs urls. I appreciate that this cannot be done with tor and bitcoin right now, but is there a more general reason why that will never be possible? An inherent problem with tor seems like the most likely reason (I don't know alot about how tor works)

We have tax exemptions for the rich, but the poor and middle class must suffer when these Bankers and politicians makes mistakes.

I say, F@CK them!

Right, I'm with you


Reward the Poor & middle class, if they lose money on high risk investments and stop bailing out these fat cats.

Don't agree. No-one should be rewarded for making mistake, incentives to do smart things must be in place for everyone, the alternative is to squander resources on people who don't make productive use of those resources. Gaming that would be easy:

1. Invest in high risk high yield asset
2. Lose everything
3. Say "I'm poor, bailout please!"
4. Back to 1
1766  Bitcoin / Press / Re: [2018-08-20] After the Bitcoin Boom: Hard Lessons for Cryptocurrency Investors on: August 21, 2018, 12:25:07 AM
But I don't think about it as a doomsday scenario, because the technology will endure, the original chain might lose a portion of its hashrate, nodes and users, but those who value its principles will stay. Worst case scenario, oldschool Bitcoiners will have to switch to some other coins or create new ones.

It's always been said that the risk of exactly that kind of cat and mouse dynamic will preclude the disaster, but it seems like a precarious assumption, and it's unchartered territory. And of course sheer innovation may rule it out, although what form that takes is of course unknown except to whoever invents it.
1767  Bitcoin / Press / Re: [2018-08-20] After the Bitcoin Boom: Hard Lessons for Cryptocurrency Investors on: August 20, 2018, 09:28:12 PM
How illiterate one should be to put all his savings in something so volatile as bitcoin.

How dumb does one have to be to jump into the market that has been booming for 2 years and just recently went parabolic?

the "hard lesson" here is don't be so stupid with your money.


You all sound like you've got a pretty responsible "caveat emptor" attitude toward asset investing. There's a problem with that.

These fools are going to become more numerous over time, Bitcoin's growing popularity is going to make the situation much worse. Eventually though, there will be too many of them, and government re-distributionist types can exploit the situation by offering them their money back. The worst case is serious: imagine a country with existing bad inflation problems proposing to bail out people who lost everything on, say, a next-gen crypto that then went to zero. If solving the problem using central bank credit is considered too high risk, then crypto profits will be targeted instead.

In those circumstances, governments might try to destroy Bitcoin by using confiscation to get the economic majority, then using that power to push a hard fork to centralisation. If you believe you would submit to confiscation of your BTC in those most difficult of cricumstances, then think carefully what you would be risking: not just your own monetary sovereignty, but that of the Bitcoiners who refuse to comply. I don't think this risk is high, but in any circumstances, remember that every satoshi that falls into the wrong hands can be used to push Bitcoin into a centralised hard fork. You have a responsibility to both yourself and the rest of the Bitcoin users, take heed.

You can verify that it's over Tor because the peer will appear to have the IP address of your Tor proxy server, with a random port.

Right, I intended to include a question about that, namely:

If the IP of the incoming connection is that of my tor proxy, will misbehaving peers still be banned effectively? It seems to me that without knowing the originating IP, they can attack my node by getting my proxy's IP banned instead of their own.


Also, trying to use bind=<proxy IP> gives this fatal startup error:
Code:
Unable to bind to <proxy IP>:18333 on this computer (bind returned error Cannot assign requested address (99))
What is error 99?
It means you don't own that IP address. You're supposed to bind to one (or more) of your own addresses, specifically the one specified in the HiddenServicePort entry in torrc. Note that this is only necessary if you need to avoid receiving incoming connections on your other addresses (in particular your public IP address, if you have one, which would compromise your anonymity).

Right, so 127.0.0.1 is the IP for the bind setting?


Or, should I simply be expecting low numbers of incoming connections over tor?
I usually have at least 10 or so, but it seems to be normal for a new hidden service to not see many connections at first.

Ah, that's good to hear, in a way. So just need to wait a little.

When you say "at least 10", do you mean 10 incoming connection, or in total?
1770  Bitcoin / Bitcoin Technical Support / Incoming connections/Port forwarding: is bind=<IP> needed, and why? on: August 20, 2018, 12:45:05 PM
Trying to get incoming connections over tor, and it's a mixed success.

I have a static hs for the node (and so I have -listenonion=0), and I got just 1 incoming connection that actually used the NETWORK service (also BLOOM and WITNESS, all other nodes were crawling nodes without any services). That was a stable long lasting connection, so maybe it's working...

But there are alot of debug messages like
Code:
Socks5() connect to <ip:port> failed: connection refused
...so it seems that there could be something in the config that's preventing the majority of peers connecting to the node.

Also, trying to use bind=<proxy IP> gives this fatal startup error:
Code:
Unable to bind to <proxy IP>:18333 on this computer (bind returned error Cannot assign requested address (99))
What is error 99?

Or, should I simply be expecting low numbers of incoming connections over tor?

1772  Other / Serious discussion / Re: Is it right to kill a violent burglar? on: August 17, 2018, 10:43:52 AM
what about protecting your family? children? sisters, grandma?

You two have no idea of reality. Try waking up at 2am with a bunch of robbers running through your house? believe me you're not thinking of "disarming" lol....... if you break in to do any crime, being where your not supposed to be, expect to be met with brutal force!

Right, I agree pretty much. But that doesn't change what I said really; if you're pointing a gun at a trespasser, and you shoot them in a space like a house, it doesn't matter how hard you try, the chances of killing them are pretty high. Presumably you would go for the head shot though, right?

There's about as much chance of succeeding with attempting to kill as there is of trying to do minimal damage. Let's put it this way: if I confronted an intruder and they were a safe distance from me or anyone else, I'd warn them to drop everything and get out, without shooting. But if the confrontation happened too close for comfort, I think I'd just shoot them quickly without a word.  

So really, heed your own words. If this actually happened to you, would you really turn into Arnold Schwarzenegger in a 'roid rage? Or would you do everything to prevent the situation escalating to something more dangerous? I think you'd be more likely to come out of it better if you don't deliberately take extreme or risky courses of action.
1773  Bitcoin / Press / Re: [2018-08-15] Is Bitcoin A “Cult”? A Former Paypal CEO Seems To Think So on: August 17, 2018, 10:17:09 AM
"Cult" is just a perjorative way of labelling a culture (it's essentially the same word). Typically, anything labeled a cult has obviously unhealthy social/systemic dynamics to those observing from the outside.

Satoshi made that same observation, but about the culture of mainstream banking and finance. Time will tell how accurate these mutually biased observations are, but it's very tempting to state here and now: Bitcoin has been a gradually improving success since it's existed, while the mainstream financial system has at best been treading water.

Using technology/information and business monopolies, governments are getting closer than ever before to having absolute power. Please stop supporting them everybody, history will not judge you well.
We are already doing it. Bitcoin, decentralized technology are the answers.

Unfortunately, you'd be surprised how many people on bitcointalk.org support the democratic government concept in 2018 (it used to be far less than that 5-6 years ago).
1775  Other / Serious discussion / Re: Is it right to kill a violent burglar? on: August 15, 2018, 07:01:18 PM
It is sad what is happening into our society but if you can by any means can disable the burglar its a much better way than killing.

Exactly, the idea is to protect your property from theft and trespass, not to take revenge for the robbery they were prevented from committing as a consequence of killing them. That still carries a high risk that they will be killed, of course. 
1776  Bitcoin / Development & Technical Discussion / Re: Lightning Network Discussion Thread on: August 13, 2018, 10:31:22 PM
After the new OPcode added, there would still be something else replacing the penalty system to keep Lightning transactions "honest".

Zin-Zing was pointing out that the users do not have control of their Bitcoins in Lightning because they can be penalized or because they have to wait for some time to receive your coins after broadcasting the latest state of their channel.
That's exactly why I would like more research going into sidechains. A LN transaction can be fairly safe, but it cannot be compared to a Bitcoin on-chain transaction, as there is some "loss of control" involved.

So, when an improvement to a new paradigm is on the table, that's somehow a reason to want other people to invest time and energy into contemplating an extension of an old paradigm? That doesn't make any sense
1777  Bitcoin / Development & Technical Discussion / Re: Lightning Network Discussion Thread on: August 13, 2018, 08:22:39 PM
But that is not the point.

Yes it was, and it was the point I replied to. I would never reply directly or indirectly to the user you were talking to (who I think is a banned user evading a ban)
1778  Bitcoin / Development & Technical Discussion / Re: Hard forking with a mature LN on: August 08, 2018, 07:43:24 PM
I have re-thought about the "scam potential" in this context (I've also searched the lightning-dev mailing list for related discussion, but without success) and I now tend to agree that while a certain danger exists, it may not be relevant enough to change the Lightning code to follow hard forks, because of the following reasons:

I'm pretty sure the code itself contains logic that responds to forks, but I'm not at all familiar with it. The reason why that sort of thing hasn't appeared on the Lightning mailing list is that it's not about Lightning as a protocol, and presumably would be discussed on the bitcoin list instead


1) Bigger hard forks almost always implement some form of replay protection, which would make this attack impossible because the old "state transaction" wouldn't be valid in this chain - both parties would have to re-sign it
2) A hard fork without replay protection, which results in a coin of significant value, is not an event that happens every day. If it happens, it is maybe enough to simply react manually (with a LN code update).
3) I have thought about a scenario when an attacker launches multiple forks without replay protection to make (automatic) following of every chain almost impossible and then attack LN channels, but it is very unlikely that these forks could achieve any significant price. So the attacker would sit on a lot of worthless coins and even is in danger to expose his secret and lose his BTC holdings in LN channels (if LN-penalty is used).

The airdrop problem (when in the case of hard forks with replay protection, LN users woudn't get benefitted automatically with "free coins") would persist, however. But are fork-airdrops really a critical feature for most users? BCH may have been an unique fork in the sense that it was able to achieve a price of 10% of the BTC price and more, while most other forks are, at best, near the 1% mark.

If we ignore the fact that removing the tx replay attack has been proposed (and so might be rendered irrelevant in future anyway), I agree that the effects of hard forks not by the Core devs will be negligible, and may even make such forks sufficiently more difficult to execute that they become less realistic (at a minimum the potential for forking changes to the consensus code becomes either narrower in scope, or more difficult to write in a way that maintains the stability of payment channels that exist on the new blockchain post-fork)

When it comes to hard forks that the Core devs design, I refer to my previous answer: both sets of devs, both for Lightning implementations and the Bitcoin blockchain are aware that problems are possible. If Andreas Antonopolous wasn't prepared to answer that question, then that's not a significant thing to happen, he had less than a few seconds to consider the implications and answered a general question with a decent general answer. An accomplished cryptocurrency programmer would almost certainly have provided a more substantial reply, but that's not Andreas' job.
1779  Bitcoin / Development & Technical Discussion / Re: Hard forking with a mature LN on: August 07, 2018, 08:21:56 PM
Huh

Andreas Antonopoulos doesn't know the answer to a question, WHAT ARE WE GOING TO DO


I'm not sure if anyone's noticed, but Andreas is just a guy who ends up in common Bitcoin based videos on the internet. He's not a developer for any implementation of Bitcoin or Lightning, or for anything. So what has his lack of preparation for such a question, 1 time, got to do with anything at all?

FYI, Lightning devs are aware of the issues with hard forks. Maybe the real problem is that you're not looking for information in a place you could actually expect to find answers.
1780  Other / Ivory Tower / Re: How do you see bitcoin in 10 years’ time? on: August 07, 2018, 06:36:34 PM
The only thing keeping Bitcoin's price up is the belief that it will go up in the future and the black market.

I wouldn't be so dismissive of the "black market", that's a biiiiig market, and it's always going to be there.

And the more Bitcoin is improved, the more the black free market will improve too. Bitcoin was designed to be an anti-government, free market tool.
