9201  Bitcoin / Legal / Re: Decentralized Law - How Do We Get There? on: January 15, 2020, 12:04:05 PM
Feel free criticize and improve!

Main article: https://decentralizedlegalsystem.com/law/



I read your article and I have some comments:

1 - Governments don't really create laws anymore,  specially since French revolution.  Ok, governments do, but they are not the main creators of law: the parlament is (the house and the Senate in most countries).

Unless you are in a very authoritarian regime, governments just create a few laws.  This is due to the separation of powers, also know as checks and balances.

Government is the Executive,  the Parlament is the legislator and the Judiciary are the judges of the laws created by the parliament.

This is good, because the parlament is way more decentralized(hundreds of members) than the government (one person)

This first part you should verify , because anyone who understands a little about laws will notice this mistake.

2 international law.
Those are created by governments and just confirmed (or not) by the local parliaments.

Those laws are centralized imo. They are throw away by the UN (Which is controlled by some people), and reduces the soberany of countries.  A global government is way worse and centralized than a lot of smaller ones.
9202  Economy / Reputation / Re: [Doubt the possibility of a scam] BestChange Bounty and Signature Campaign. on: January 15, 2020, 11:38:40 AM
Are you guys actually being serious? While I am really a person to support ANY possible scam attempt, that scam accusation is a complete joke and actually a desaster - sorry but thats my 2 cents even though I am still a very newbie in this forum.
I can see you are very newbie then  Cheesy

From the Trust Summary Page:

Code:
    Positive - You think that this person is unlikely to scam anyone.
    Neutral - Other comments.
    Negative - You think that trading with this person is high-risk.

He is just saying that trading with this person is high-risk of losing money. He is correct, because they refuse to escrow, and that doesn't make any sense.

If they are willing to pay, why can't they pay upfront to a trusted escrow as they have no reputation? Actually, they have a BAD reputation.
Something "right" is clearly wrong here. If they want to advertise here, that is not the proper way.

If they are refusing to use escrow, there are 2 options:
1 - they are scammers and will never pay
2 - they are newbies, and newbies don't know what they are doing, so you may still not receive your money.

They refused to use escrow so they are untrustworthy. There is no two ways about it, why should we trust them and let them have the opportunity to not pay? What on earth gives them immediate credibility here?

Nothing at all wrong with us requesting they use escrow, more importantly why are they not willing to use escrow?
Why should they pay someone when they have in-house staff to be in charge of it?

Because I don't trust their in-house staff, I don't trust their house, I don't trust their staff, and I don't care about them. I don't want to trust them, I don't want to care about them, and I don't give a shit about them. I just want my money trusting the fewer people as possible. I know I need to trust someone, so I prefer to trust a trusted escrow than to trust an unknown exchange. This is how things works here.
9203  Bitcoin / Hardware wallets / Re: Ledger Nano X vs. Nano S on: January 15, 2020, 01:00:26 AM
I would buy a Nano S.

The best has no big difference, and personally I would not carry my saving around where I go.
It is likely that someone could try to rob me (physically) if I keep carrying a stuff like this around, and force me to give my Bitcoins. I live in Brazil, maybe you don't have that problem where you live.

Anyway, I see no good reason to upgrade. You can have 3 blockchains installed. I have in mine BTC ETH and XRP, they work very well, and I can carry all my shitcoins in the Eth chain.

I like to keep some money in my mobile device, so I can have some bitcoins wherever I go. I was never able to buy anything with those bitcoins, but I was able to give them as a gift to some friends (to people I could not convince to buy BTC, so I gave them lol). I see no reason to carry a hardware wallet around.... Unless you have 2.

9205  Alternate cryptocurrencies / Altcoin Discussion / Re: Why We Need Bitcoin, If Altcoins Transfers Are Faster And Cheaper on: January 14, 2020, 04:31:49 PM
This is why: https://howmanyconfs.com/

Altcoins are faster because they are far less secure than bitcoin. Even the fastest altcoin Ethereum still takes 9 hours to be as secure as 6 bitcoin confirmations, and the other altcoins are comically slower, taking days to months to reach the same security bitcoin does in an hour.

I trade small amounts of bitcoin frequently and it is perfectly usable. If you desire instant confirmation, then think about starting to use Lightning.

Using altcoins are not even less secure, but thy are centralized.

If you don't care about decentralization,  you don't need cryptocurrencies.  Just use Visa.
Visa is faster and safer than any altcoins out there

We love bitcoin not because it is cheap or fast, but because no one controls it

Does one really need a DT status too speak for what they feel right?

I believe you should do whatever you want and you believe is right and do not care if you are going to stay in dt or not.
DT rules changes and your status come and go, but your reputation stays.

I think you should be more careful when leaving a green trust than when leaving a red one.
I wouldn't mark and account green until I received lots of payments from that account or having a long interaction

Probably, as I expect the banking world will start to build or buy mining farms as they increase their Bitcoin holdings.

If an Bitcoin ETF really shows up (what i believe is inevitable) we will soon see financial assets backed by bitcoins, fractional banking with bitcoin and so on. Banks will come in the next bull run, imo.

All this drama of energy costs will come to an end as well. Actually, energy costs of bitcoin mining is not a serious topic  imo.

Energy consumption is so far the only way to secure the network. The more energy we expend, the more secure we are. That´s the way bitcoin is designed.

Decentralized money is important now, as it can prevent wars, help fight poverty, give people freedom, etc.

It is up to other industries to build a more sustainable energy matrix.

I disagree the Tag and I am going to counter yours. And I will tag them if they do not pay their participants as they promised.

then you are on my distrust list now as you are going to give them an un earned green mark you fool

I agree with TMAN here.
The new Trust system does not work like this anymore Royse777, you cannot counter a red tag with a green one. They will be marked as +1 and -1.

The green mark you gave them is un earned and certainly not deserved.

a -1 red tag is more deserving than your green one. Their attitude is suspicious and anyone dealing with them may lose money.

Edit: What is terrible about the +1 in their account, is that newbies can think the account should be trusted, while they clearly can't trust them. They may prove themselves to be trusted (if they pay), but they are promising high payment without any escrow.
9210  Bitcoin / Legal / Re: Decentralized Law - How Do We Get There? on: January 14, 2020, 10:59:34 AM
I think the closest we can get to "decentralized law" we already have: referendum and plebiscites.

When everyone is able to vote, the decision is "decentralized".

as wikipedia says:
" referendum is a direct and universal vote in which an entire electorate is invited to vote on a particular proposal and can have nationwide or local forms."
This is decentralization. https://en.wikipedia.org/wiki/Referendum

However, as I read somewhere in this forum, democracy is vulnerable to a 51% attack. If someone manages to get the appropriate attention through media or the internet or whatever, he may be able to control 51% of the votes.
9211  Bitcoin / Development & Technical Discussion / Re: Energy requirements to brute force SHA-256 on: January 13, 2020, 09:03:34 PM
I'm not even sure if you simply don't understand or are trolling.
Again: a hash doesn't contain the information to reverse it.
This is not a matter of finding "patterns".
Information that isn't there can not be found.
Thermodynamics / information theory (entropy) is in the way.

I took some time to read some texts related to the subject, and nothing I read said that "information is not there to be found".
Information is there, but highly scrambled.

Some interesting quotes from this answer (2nd answer on the topic), which is the best I found.

Quote
It is unclear whether one-way functions can actually exist. Right now, we have many functions that no one knows how to invert; but this does not mean that they are impossible to invert, in a mathematical sense. Note, though, that it is not proven that one-way functions cannot exist, so hope remains.

Quote
There are some functions which can be linked to well-known hard problems. For instance, if n is the product of two big primes, then the function x ⟼ x2 mod n is hard to invert: being able to compute square roots modulo a non-prime integer n (on a general basis) is equivalent to being able to factor n, and that problem is known to be hard. Not proven to be hard, mind you; only that mathematicians have tried to efficiently factor big integers for (at least) the last 2500 years, and although some progress has been made, none of these smart people found a really killer algorithm for that.

This problem is mainly related to https://en.wikipedia.org/wiki/Integer_factorization where it is very hard to factorize very big subprime numbers. Factorize is to decompose a number into a product of smaller integers.



This was a good example based on the above problem. But it is still reversible, we just don't know how to easily do it.

Quote
Let me invent a simple "password hashing algorithm" to show you how it works. Unlike the other examples in this thread, this one is actually viable, if you can live with a few bizarre password restrictions. Your password is two large prime numbers, x and y. For example:

x = 48112959837082048697
y = 54673257461630679457
You can easily write a computer program to calculate xy in O(N^2) time, where N is the number of digits in x and y. (Basically that means that it takes four times as long if the numbers are twice as long. There are faster algorithms, but that's irrelevant.) Store xy in the password database.

x*y = 2630492240413883318777134293253671517529
A child in fifth grade, given enough scratch paper, could figure out that answer. But how do you reverse it? There are many algorithms people have devised for factoring large numbers, but even the best algorithms are slow compared to how quickly you can multiply x by y. And none of those algorithms could be performed by a fifth grader, unless the numbers were very small (e.g., x=3, y=5).

On the post I mentioned on stack exchange he explained how MD5 is hard to invert. It is interesting, and the main problem is related to bit depency, which is :
Quote
Bit dependency: A hash algorithm is designed to ensure that each bit of the output is dependent upon every bit in the input. https://crypto.stackexchange.com/questions/45377/why-cant-we-reverse-hashes

Quote
At that point you begin to understand the problem of inverting MD5: every time you touch a single bit, it triggers an awful lot of modifications throughout the algorithm, which you need to cancel out by touching other bits, and there are just too many interactions. Basically, you juggle with 2128 balls at the same time, and that's way too much to keep track of all of them.
~

So, I looks to be possible. Just not humanly doable. From time to time even some hash functions are considered broken, just like SHA-1 which became vulnerable to shattred attack  (read it  here https://en.wikipedia.org/wiki/Cryptographic_hash_function)

So, personally, I would use your qwk's Planetary Super Efficienty Computer to try to break those hash functions instead of brute forcing them.
9212  Bitcoin / Bitcoin Discussion / Re: What ever happened to Hal Finney's bitcoin? on: January 13, 2020, 08:07:00 PM

As above I wonder how much of it was eaten in medical costs.

Probably a lot, but their heirs got some



The next I heard of Bitcoin was late 2010, when I was surprised to find that it was not only still going, bitcoins actually had monetary value. I dusted off my old wallet, and was relieved to discover that my bitcoins were still there. As the price climbed up to real money, I transferred the coins into an offline wallet, where hopefully they'll be worth something to my heirs.



Did they already move it?

I believe those btc addresses are not public.  He probably worried about his privacy and his heirs.

I applied for this campaign many times but could never join. Sad news to see it coming to an end,  but it is nice to see it got good results.
9214  Bitcoin / Development & Technical Discussion / Re: Energy requirements to brute force SHA-256 on: January 13, 2020, 04:26:22 PM
if you want to understand why it is not possible to reverse a hash, i already gave a good example above. and you don't need a super computer or an AI to try and reverse it. basically the reason is the same. you can not reverse (a+b=18) to find a and b because there simply is no way! and lets not confuse guessing different values for a and b with reversing.

what hash algorithms do is the same, it is math. it is a bunch of additions, bit shifts, bit rotates,... in multiple steps that will return a final result. you can not reverse even a single step let alone the entire process.

I am not convinced, but I didn't read about it yet.
I am not convinced because we have unlimited samples, not just one.

If you have one more samples everything changes.
a+b=18
A-b=1
You can easily determine now. I know it is not that simple, however we have unlimited examples. That's the idea. Teach a machine to train on those examples searching for any kind of pattern.

But we are all just repeating ourselves already...

To break something like this would turn the world into chaos. Blocks could ne mined at will, bank accounts  easily accessed , financial system... probably someone is already looking for this im secrecy
9215  Economy / Services / Re: Need referral link from binance on: January 13, 2020, 12:55:20 PM
Binance allow users to generate a custom referral link with customized fees sharing.
For example, VIP accounts can have 40% fees discount (if they own a lot of bnb)
That 40% can be shared between me and my friends, until 20% each.

I don't have such account, but I can give you a link with 10% for me and 10% for you.
Are you interested? I just sent you a PM with my referral.
9216  Other / Beginners & Help / Re: bitcoin lightning network on: January 13, 2020, 12:21:02 PM
I doubt that although I had confusion earlier on the other thread of BitCryptex. When we open or close channel, we do need of On Chain transaction which is increase in a significant numbers once LN gets a good adoption. You will certainly not be holding your big sum on LN for a long time.
There's exchange option for LN BTC to On Chain BTC which will increase as well. People will mostly utilize this to increase inbound

I believe the idea is to keep your savings in cold storage, and to keep your monthly expenses in a LN channel. Avoid closing that channel, only when necessary to avoid paying fees again.

And you just round your channel every month or so to pay the next month expenses.
9217  Bitcoin / Development & Technical Discussion / Re: Energy requirements to brute force SHA-256 on: January 12, 2020, 10:56:35 PM
The string "Tbptjblbnpp" doesn't contain (all of) the information to create the string "Satoshi Nakamoto".
No matter if you use mathematics, mechanics, chemistry or anything other than magic, there's no way to get from one to the other.



The tbptjjsja have the information to create the string. However it is very hard to find that pattern, specially with a single example.

However you unlimited amounts of examples of SHA256 to learn from them seeking for that pattern.
Imagine to train a software to train on those examples seeking for that pattern, with huge processing power and an efficient code.
I believe this is something very interesting and doable.

Maybe  not to really break it , but to hugely  narrow the possibilities . Like I your example,  just look for ome single character swap

I never researched about it, just had this idea.

There's been some advancements in AI over recent years, and there are promising results from various sources. However, these are niche specific, and none of them are related to deconstructing SHA 256 or reversing a hash of SHA

Maybe some people are researching in secret ..?
9218  Bitcoin / Development & Technical Discussion / Re: Energy requirements to brute force SHA-256 on: January 12, 2020, 07:52:39 PM
Yes, it is.
AIs don't magically overcome the laws of mathematics Wink
A (good) hash doesn't contain the information of its input/s.
With no information to go on, there's nothing to "reverse".

I was not thinking about magic, but about math  just like your example.

Quote
Now, what you could do instead of writing the names of guests on the list, is write hashes of their names.
A very simple (not really good) hash could be:
1. shift one letter in the alphabet (ROT-1)
2. leave out all vowels

So, a name like "Satoshi Nakamoto" would turn into:
1. Tbuptij Oblbnpup
2. Tbptjblbnpp

This is 100% reversible.
I would like to understand more, and I don't this was a good example...is it not reversible with our current math or not at all? Our paradigms may change in the future

I will take a further look at this.
9219  Bitcoin / Development & Technical Discussion / Re: Energy requirements to brute force SHA-256 on: January 12, 2020, 06:02:18 PM
I believe that trying to brute force a hash 256 is the wrong approach. This won't work.

I was thinking about something more effective and efficient (energy speaking).

What if some tries to create an AI that would try to reverse SHA 256 hashes? That is not impossible. Although no one never succeeded , a highly advanced and dedicated AI could try.

I believe that with AI advances a lot of things will change.
9220  Economy / Service Discussion / Re: Cryptotalk Future on: January 12, 2020, 04:43:27 PM
A forum need a project behind it to have a sustainable traffic.
And hat project cannot be bitcoin, because it is already the project behind this forum.

Cryptotalk need something new to offer. A new idea, some innovation which would make people visit it
This things take time and it would take years before it is a well know site. Slow and steady, there are no shortcuts.

Imo, that forum is just a waste of resources which could be used funding new ideas which would bring innovation, not spammers who don't k ow what they are talking about.

Paying spammers to spam there is just a waste of resources. It will never work.

Maybe if they hired only very selected users, to create relevant content in their website (not only here)...
