1. it steals, not stills (evil maid)
2. I think that you've missed Man in the Middle attacks. Ledger had this vulnerability in 2018 and in theory it's fixed, but newer HWs may be vulnerable to that without knowing it yet. So I would not rule this out.


I find HW a great tool for every day payments, but not really for keeping life changing amounts on them. And your pretty impressive list tells that I'm right about this.

What do you think the world will be today without Bitcoin? Your input will be greatly appreciated. Thank you. Smiley

95+% of the world today still goes on without knowing or at least caring about Bitcoin.
If you are serious about this topic you should really widen your circle of friends and acquaintances...

That said, is it possible a crypto currency equivalent could be in the works?

Could this concept work to improve environmental policy? What do people think?   Smiley

No, sorry.
I've read only parts of the text (it's big...), but no, imho this won't work.

With the current system, the ones doing good already have their incentive - they can sell those carbon "shares" to the wrongdoers. And this makes the polluting businesses have to pay for their actions.
All the businesses care about is money. And imho the only way way to make them do good is to increase - year after year - the "toll" they have to pay for their wrong doing.
If you only reward the "good" businesses, that's nothing. The bad businesses may earn more continuing to pollute than by improving their habits (i.e. upgrade their technology).

So there's a working system and the only thing that can be made to improve it is to continuously increase the financial burden for the polluters. I see it as an opposite of your proposal (which gives more rewards to the good).
7564  Bitcoin / Project Development / Re: Distributed database project on: March 05, 2021, 09:03:59 AM
Thanks for your valuable comments. Here comes the logic of generating coins. Data miners can collect some of the coins we produce when there is no demand. So it's kind of like an airdrop process. I think we can implement a policy to prevent miners from exiting the system with this transaction. This is exactly why we want to produce coins. Would it be a logical action in your opinion?

Having your own coin is a tricky direction. You have to advertise it. You have to make it valuable. You have to pay exchanges to trade it. It can easily become the failure point of your project.
I would rather divert the miners do different lucrative tasks that can still produce money (for example actual mining) instead of coming with my own coin. But it's really up to you, it's your project.
7565  Bitcoin / Project Development / Re: Distributed database project on: March 05, 2021, 08:21:28 AM
I agree with joniboini here. You don't need your own coin/token for this.

You can make some sort of "shop" where some will "order" work, pay for it and you can take your cut and which also acts like a mining pool and based on the work done, the accounts of the workers will accumulate money. And that money can be in any form, from Bitcoin to major altcoins or even fiat.

The problem you may have to think about would be what happens when you have "miners" and no orders. Since the miners may find some other work to do if you don't have anything to offer and they may be gone for good.
7566  Bitcoin / Hardware wallets / Re: hardware wallet on: March 05, 2021, 07:37:24 AM
Clearly a new generation of HW should come with better protection against tampering.

And a feature could be to also sell it as a package of parts that can be put together easily without tools. The parts don't have to be complicated, but once put together they cannot be taken apart without damage. And the device cannot run/get powered without such assembly. Something like this could ensure that the buyer is the first one running the device, hence the firmware is 100% sure not "touched". (Maybe the idea can be improved though).

There's a big difference between merely running a computer 24/7 without touching the disk much and actually utilizing the disk constantly. Also disks have a much longer lifetime than just a few months, some sources put them at 5 years.

A disk that runs constantly only runs into the risk of getting bad sectors, where data inside it is lost and for a disk that mostly has blocks and undo data on it, will indeed corrupt some of them and require a reindex. But most disks won't be damaged like that quickly, just don't drop the disk or tip over the case tower holding it while it's writing to it because that could get the disk platter scratched and destroy the whole disk.

I know all this.
There was not constant HDD access, but there was pretty much access. After the initial sync Bitcoin Core also don't need "constant" access either.
And the HDDs have worked way more than the expected 5 years, just after around 5-7 years they got retired i.e. less use and non-essential one; last time I've seen them working days before the pandemic.
And I didn't encounter any bad sectors.

It may worth adding that (many) browser extensions also can basically read everything you do online, still many people use (too many of) them when accessing everything, including ... exchanges and web wallets.


If an extension has access to all the web pages you visit, it can do practically anything. It could function as a keylogger to capture your passwords and credit card details
7570  Economy / Collectibles / Re: Does having 0.001 BTC it's worthless? on: March 04, 2021, 05:48:53 PM
does saving Bitcoin on Chip 0.001 or Coin 0.001 are being worthless in future?

When Bitcoin price stabilizes (no big fluctuations for more days in row), the mempool tends to free up and the tx fees also tend to decrease.
If you have the patience to HODL it, you'll also have the patience to cash in if you want.
Also as collectible you may sell it some day (preferably not in the next 5 years) as a whole and the buyer will have to handle the tx fee or whatever means of payment you guys will be using.
7571  Other / Meta / Re: Post still exist of a nuked user, forum bug? on: March 04, 2021, 04:39:46 PM
Is that forum bug?

There was a similar topic not long ago. I don't know if it's the same situation here, but there the answer was:

This user was nuked and then he was manually reactivated and the posts restored. This results in the behavior as described by you.
Posts and activity remains in such cases on 0 but this is a bug that is negligible. Such a situation is an exception and therefore not worth more effort.
7572  Bitcoin / Project Development / Re: Make Bitcoin Green! on: March 04, 2021, 04:33:59 PM
It was already said a couple posts ago that the nodes aren't the ones drawing much energy. The topic is greatly misleading.
And you guys should not make this thread an altcoin fiesta, unless you want to move it to altcoins section.


Now back to topic:

I like the idea of this project: a silent Bitcoin node.
And while reading another topic something has occurred to me: how is the HDD doing over time? If it would not be an old HDD, wouldn't a 512GB microSD card be more appropriate for this setup?

And something else: if this setup is already done and running, wouldn't an ElectrumX (or similar) service come as an obvious "next step"? Is the overhead/extra disk space significant?
7573  Alternate cryptocurrencies / Altcoin Discussion / Re: What happens if a stable coin fails. on: March 04, 2021, 04:19:43 PM
Hi,

Just a novice question here: what happens if you hold x amount of a stable coin in one of the many lending crypto platforms available (crypto.com, youhodler, nexo, etc) and that coin fails and goes Kaput? Do you loose it all? or are your assets moved to another token or FIAT?
 

If I understood the question right then:
1. If the value of the stablecoin will drop to 0, you will end up with the same number of coins, just now they will worth 0.
2. If the coin underlying architecture (blockchain) fails then you (and everybody else) will be unable to withdraw (and also most probably the value will drop).

I am not familiar with those platforms, but why would they exchange the worthless coins into something valuable (hence lose money) because you made a bad investment?
7574  Bitcoin / Bitcoin Technical Support / Re: Hard drive full midway thru blockchain download on: March 04, 2021, 12:09:30 PM
Well, following is a rhetorical question but I’d still like to ask. Is an internal drive (which runs 24/7)  protected from a failure?

I'll ignore the "rhetorical" part and I'll answer Smiley
I expect most computers' HDDs not be designed to run 24/7. The theory nowadays tells that if one has installed there proper NAS HDD, he should be fine.

However, I've been using (in the last 20 years) in many occasions computers 24/7 for many months with no visible consequences on the HDD. I don't expect the same with external HDD.
7575  Economy / Speculation / Re: Tim Draper: Netflix will be the next one to fall on: March 04, 2021, 08:18:42 AM
They can increase their valuation just by doing that.

With the increased competition from Amazon, Disney and whoever else is coming, with quite a significant part of the potential income not coming in because of illegal accounts and account sharing, I think that if they make their move quick enough, Bitcoin can become their safety net between a "happy life" and really big problems.
In the same way Tesla, as big as it is, didn't really have profit yet from selling cars and Bitcoin came so very handy, I think that Netflix is basically in a quite similar situation and may profit in the same way.
I think that this could have been Tim Draper's logic and I tend to agree with it. I don't know if Netflix board is on the same page though  Grin
7576  Local / Bine ai venit! / Re: monero on: March 04, 2021, 08:06:57 AM
si 50-50% ori am gresit eu, ori mi-a dat teapa, cand am dat submit, din 0,09694029 s-a trimis 1xmr

Umm.. ai mai verificat portmoneul de atunci?
Nu am mai trimis XMR de tare mult timp, dar principiul este acelasi ca la Bitcoin: cand trimiti o suma undeva, cum inputul este cel mai probabil mai mare decat acea suma, tu vei trimite intr-adevar intreaga "bancnota" (sa zicem) si vei primi inapoi restul, cand tranzactia este confirmata. In functie de portmoneul folosit, acea suma poate sa se intoarca fie la adresa (de portmoneu) de unde s-au trimis banii, fie la alta adresa din acelasi portmoneu (aceast a doua parte este asa la Bitcoin, nu stiu sigur daca este asa la Monero). Ideea este sa verifici (sapi) ca ar trebui sa fie sanse bune ca acei 0.9 XMR sa se fi intors la tine intr-un fel sau altul.



3. Ai mentionat pretul de 60€; in afara de Ledger si Trezor, ce alt device gasesti tot in acest price range care sa aiba si un istoric ok si sa fie open-source?

Nu. Dar deja si tu zici aici ca nu e doar Ledger, e si Trezor...  Smiley
Lasand gluma la o parte, greseala mea, nu stiam ca Trezor-ul de 60 EUR nu stie XMR.

4. Nu stiu de unde ai impresia ca exagerez; Ledger are un Secure Element despre care au spus in mod clar ca este closed-source. Este singurul component care nu are sursa deschisa din produsele lor. Faptul ca exista acest component si ca nu poti folosi un Ledger (cel putin cu altcoins) fara a trece intai prin Ledger Live (care la randul lui trebuie sa aiba conexiune la internet pentru a functiona!!) imi ridica un semn de intrebare referitor la ceea ce se intampla "dupa cortine".

La intrebarea "de ce nu ati face ceva rau din moment ce device-ul vostru este partial closed-source?", raspunsul Ledger a fost practic faptul ca nu si-ar pata imaginea si sa intre in probleme juridice pentru o teapa. Mi s-a parut un motiv destul de banal.

Iar legat de telefoanele ascultate... cauta simplu si scurt pe domnul Google "SRI asculta telefoanele" si vezi ce gasesti. Smiley

Cum FBI & Co stiu sa asculte de vreo 85 de ani, chiar as fi ciudat sa ma mir ca "au aflat" si ai nosti  Grin
Ma refeream ca pari sa te astepti ca HW incepe sa trimita informatii "acasa" de cum il conectezi.

Da, Ledger Live ar putea face asta, desi daca se apuca sa faca asta cred ca se va afla mai devreme sau mai tarziu, iscand un scandal si mai mare.
Dar din ce vad, poti folosi Ledger cu Monero si fara Ledger Live.

Compatible with hardware wallets such Trezor and Ledger
7577  Bitcoin / Bitcoin Discussion / Re: How will Quantum computing affect Bitcoin? on: March 04, 2021, 07:41:15 AM
Quantum computers are exceptionally costly to build and only a couple of nations have shown interest in it! If you think hackers will use such computers to launch an attack on cryptocurrencies like bitcoin, then you are daydreaming. Quantum computing is not yet a threat to cryptography, at least not now and not in immediate future!

Actually they've started to also build 5000$ quantum computers too. Of course, they are very weak (2 qbit) hence they don't need liquid helium for cooling.

And I think that you are also wrong about government financed quantum computers. In the same way super computers were used for crypto mining by this or that scientist with access to them, I can also expect this kind of "accidents" happen now and then with quantum computers too in the future.

But from what I've read (since there are plenty of threads here on this topic!) Bitcoin is pretty much safe from quantum computing and the only weakness (albeit theoretical) may be in the address reuse. (If I understood right). However, there are a lot of things in this world protected by cryptography, same or weaker than Bitcoin's, if this is hacked the problems will be .. generalized.
7578  Bitcoin / Bitcoin Technical Support / Re: Hard drive full midway thru blockchain download on: March 03, 2021, 12:16:05 PM
I was downloading the bitcore wallet with the entire blockchain and ran out of space on my C: drive.  I want to move it onto a portable hard drive with more space... How do I do this with out starting the download again? (I'm halfway through).
 

1. Stop Bitcoin Core and make sure it's stopped (a restart may also help).
2. Locate your data folder and move the blocks folder to the new drive (let's say move from c:\somewhere\blocks to d:\blocks-new-home)
3. run cmd as admin and (with corrected paths) do
Code:
mklink /D "c:\somewhere\blocks" "d:\blocks-new-home"

That's all.
7579  Local / Bine ai venit! / Re: monero on: March 03, 2021, 10:59:33 AM
Consider personal ca e o prostie sa investesti 60€ intr-un device care e partial closed-source daca vrei sa tii XMR pe el. Mi se pare ca e ca si cum ai cumpara XMR cu KYC si ai preda toate tranzactiile catre stat - din moment ce habar n-avem ce se intampla cu "Secure Element"-ul din Ledger, cred ca mai bine stam departe de el.

1. Exista metode sa cumperi un HW si fara sa-ti dai toate datele; doar ca inseamna sa-ti bati capul un pic. Au fost prezentate pe forum.
2. Daca cineva are HW nu inseamna neaparat ca are nush' cati bani pe el.
3. Nu zic ca trebuie sa ia Ledger.
4. Hai sa nu exageram cu "secure element" (sau nu) din HW, ca ajungem sa credem ca ne asculta si telefoanele.

Cealalta varianta ar fi Trezor-ul cel nou, modelul T. Dar e scump ca naiba.. incepusera developerii de la XMR sa lucreze la un hardware wallet special conceput pentru Monero, dar au abandonat ideea.. Deci variantele in care mai am incredere sunt cold wallet pe un calculator/laptop airgapped sau un Trezor.

Exista ceva mai multe variante, dar cum nu urmarisem preturile credeam ca cel mai ieftin Trezor costa tot pe la 60 EUR. Si da, celelalte sunt mai scumpe.
Dar (si hai sa revenim on-topic) daca OP deja a reusit sa fie tepit de 1 XMR, cred ca sunt sanse mari sa ii fie greu sa isi configureze un cold storage. Dar intr-adevar este o varianta viabila pe care ar fi trebuit sa o mentionez.
7580  Local / Bine ai venit! / Re: monero on: March 03, 2021, 06:38:04 AM
Salut,

sunt la inceput de drum, minez doar monero, am si facut rost de 1 xmr (am si pierdut-o) teapa.

sunt aici sa invat de la a la z.



Salut

Daca deja ai pierdut banutii, cred ca va trebui sa incepi prin a citi despre ce inseamna de fapt un portofel - ca banii nu sunt de fapt in el si oricine are cheile poate sa cheltuiasca tot ce este acolo - si cum sa-l pastrezi in siguranta - adica nu in mail, dropbox si de astea, ci fie pastrat mnemonic seed pe hartie, fie hardware wallet, ca cu 60 EUR puteai deja sa protejezi cei 185 EUR. In plus sa intelegi ca tranzactiile sunt ireversibile, dar doar dupa ce au fost confirmate de catre mineri.

Ar trebui sa mai citesti si despre minerit, sa fii atent ca este o activitate consumatoare de curent electric si sa nu minezi cu laptop ca ii scurtezi timpul de viata si s-ar putea sa il si prajesti sau sa-ti aprinzi locuinta.


Poate ca am inceput-o prea serios  Grin dar cum de fapt contul e din 2017, ar fi trebuit sa dai deja peste informatiile astea ... Grin
