I reviewed your post history and have concluded that you are putting in a decent amount of effort into your posts. I have given you merit, and you will rank up to a junior member.
2082  Economy / Service Discussion / Re: Coinbase After 5 days, we will automatically sell cryptocurrency in your account on: December 20, 2020, 08:33:32 AM
It sounds like you purchased some coin before a recent deposit cleared the banking system, and the deposit ultimately failed.
Is that even possible? I thought exchanges would wait until there is a clear confirmation about the transfer. Sounds like it's their mistake but the user needs to pay for it. It sounds fishy if that's true.
If I am not mistaken, Coinbase allows "instant" purchases when a credit/debit card is attached to a users' account.

It sounds like you purchased some coin before a recent deposit cleared the banking system, and the deposit ultimately failed. It sounds like as a result, you have a negative fiat balance, and Coinbase will sell any coin in your account to cover the negative fiat balance. My suggestion would be to make a deposit to cover your negative fiat balance, if you can.
2084  Bitcoin / Development & Technical Discussion / Re: Won't Bitcoin block size be resolved through simple market economics? on: December 20, 2020, 07:51:42 AM
IMO blockchain size and internet connection aren't the worst part, but rather CPU, RAM and storage speed,
1. Can the CPU verify transaction and block real time?
2. How much RAM needed to store all cached data?
3. Can the storage handle intensive read/write? Ethereum already suffering this problem
Internet connection is an important factor in being able to effectively use a full node. If you cannot quickly receive a block, none of your bullet points matter because your node will not even start verifying if a block is valid in a timely manner.

Regarding your 1st point, a user will need a CPU that can quickly validate a block.

Regarding your 2nd point, the UTXO set is held in RAM (I believe). The UTXO set is generally increasing over time, and if the maximum block size were to be increased, the UTXO set will increase at a faster rate. In theory, a portion of the UTXO set could be stored on disk based on certain criteria, and this would result in blocks that spend a UTXO stored on disk to take longer to validate. It would also potentially expose nodes to a DDoS attack if an attacker were to send many invalid blocks to nodes.
2085  Other / Beginners & Help / Re: What happend with Founder Satoshi? on: December 20, 2020, 06:57:32 AM
I think the biggest hint as to why he left the forum is in his second to last post:
It would have been nice to get this attention in any other context.  WikiLeaks has kicked the hornet's nest, and the swarm is headed towards us.
Satoshi obviously wanted to remain anonymous, and he knew the attention that WikiLeaks attracted was not going to be positive. My best guess is that satoshi believed it would be difficult to remain anonymous with the additional attention that WikiLeaks was bringing Bitcoin (and the forum).
2086  Other / Politics & Society / Re: Google down and out for 45 minutes on Monday- the perils of centralization on: December 20, 2020, 06:40:07 AM
That said, if taking bitcoin blockchain as an example, bitcoin blockchain has never been compromised before just because it is acceptable by people as miners protects it, web 3.0 will also be similar and will be protected by people just like in the case of bitcoin blockchain not by centralized body like google and the likes, and will never cease in operation like google just did for 45 minutes yesterday because it will be decentralized

It is not an uncommon occurrence for there to be over an hour between found blocks when the average is supposed to be 10 minutes.

If you are running a full node, there is a good chance that you are connecting to other nodes via google infrastructure. If you are running a full node, you are certainly relying on a centralized ISP to connect to the internet.

Decentralization has its purposes, but it is not the solution to everything. The overall performance of google products is likely greater than a hypothetical decentralized service that can help with similar tasks.
2087  Other / Politics & Society / Re: Trump contradicts Pompeo, claims Russian hack was coordinated by China on: December 20, 2020, 06:30:33 AM
You are assuming that when there are two contradictory statements, that Trump is automatically wrong.

Trump has access to more intelligence than Pompeo and a wider range of people are advising Trump. There is the obvious incentive for Trump to blame China versus Russia for the hack, considering that China is in bed with Biden and the Democrats.

Without concrete evidence one way or another, I would not assume that either party is wrong based solely on their word.
2088  Bitcoin / Development & Technical Discussion / Re: The Lightning Network FAQ on: December 20, 2020, 02:39:25 AM
Kraken has just announced that they are going to enable withdrawals and deposits over the Lightning Network in the first half of the next year.
They still have to start hiring a team to start LN implementation, but it's something Wink
I'm curious what limits they'll choose: they probably don't allow withdrawing very low amounts and I don't expect very low fees either. They don't even allow trading cents for performance reasons.
I would think the opposite. An exchange facilitating LN deposits/withdrawals will want to keep the amounts low because large transactions have the potential to make LN channels become unbalanced, and will need to be closed. Very small transactions may be prohibited to avoid database bloat.

I don't think exchanges will have especially high fees either. Deposit/withdrawal fees charged by exchanges are generally in line with actual costs associated with receiving/sending a deposit/withdrawals.

Quote
Do you think it will set off a chain reaction among other exchanges?
Probably not, but if that happens arbitrage trading is going to be fun if you can make large-transfers between exchanges in a few seconds.
I don't think LN will cause much additional arbitrage trading. Today, traders can hold both BTC and USDt on both exchange A and exchange B, execute trades on both exchanges once the price deviates by a predefined threshold, and transfer coin between exchanges after both arb trades are executed.
2089  Other / Meta / Re: Suggestion: make external links bright red on: December 19, 2020, 06:05:28 AM

[Edit] Found it. Same like this

I think something like this would be a good compromise if theymos doesn't like the negative connotation associated with red links as OgNasty says.

An intermediary page would be only a minor inconvenience, and this could even be turned off via individualized settings (that is by default, on), and certain long-standing bitcoin/crypto-related domains could be white-listed that would not initially direct to an intermediary page.

The purpose of changing a link's color is to prevent forum members from being tricked into visiting phishing sites. I think the above should generally prevent members from being tricked into visiting most phishing sites.

2091  Bitcoin / Development & Technical Discussion / Re: From node to block explorer? on: December 17, 2020, 04:55:49 AM
A block explorer will use a database to keep track of transactions and will update it as new blocks come in. It will probably not use RPC commands as it receives requests from its users.
This seems a great idea. Why haven't I thought it before... Once a new block is mined, the database will insert a new row of information. Still, though, I don't get how I'll convert the blk.dat files to csv. (So I can import it to a database)
You would run a series of RPC commands to get the transactions contained in each block. I have pseudo code describing how to import transactions into a database below:

#run for loop through each block
    #run for loop to get the txid of each transaction in the blook you are looking at
        #get the inputs, outputs, and amounts of inputs/outputs for each transaction
        #update database accordingly

Once you have updated your database with existing blocks, you can create a script to run lines 2-4 each time your node receives a new block. You will also need to account for orphaned blocks once your database matches the current blockchain.
2092  Other / Politics & Society / Re: Bet PrimeNumber7 vs. DaveF on: December 17, 2020, 04:42:52 AM

Highly doubt he'll be running in 2024. He is going to use that money to pay off campaign debts, as the campaign used a ton of money -- like many do -- and then use the rest of it for his Leadership PAC. These PAC's have a lot of free reign in regards to what he can do with it. He could finance a bid in 2024 with it, though I highly doubt be runs again.

Guy now has 200M that can dangle around the Republican party as a way to ensure that they keep him insulated from litigation from the incoming administration and to keep defending him fron NY state / other state charges.

If Trump's claims had held some amount of real evidence, that would really be something. Though that's just not the case. Claims were garbage though Republican voters are gobbling it up.

I'm curious to see how public Trump is once Biden takes office.
I doubt that the Trump campaign has that much debt. I also understand that a candidate is not personally responsible for any debt that their campaign incurs.

Some of the $200MM Trump has raised since the election has gone into his leadership PAC, and I do not doubt that this is a substantial amount, however, I also understand that Trump personally put hundreds of millions of his own dollars into getting elected in 2016 and that he entered office being a multimillionaire. If Trump wanted to exert influence on the Republican party with a lot of money, he already has the means of doing so.

I would not be surprised to see Trump hold rallies throughout the Biden/Harris Presidency, and he will probably campaign for Republicans in the 2022 midterms, who are expected to retake the House, which Trump will take credit for.

I do think that Trump had legitimate concerns about the 2020 election, but I don't think his legal team was very serious.
2093  Other / Politics & Society / Re: Silk Road’s Ulbricht Being Considered for Pardon by Trump on: December 16, 2020, 08:47:06 PM
What is that analogy? The dude sells illicit drugs and you compare him to legal entities, the knifes are just objects, it is up to the people who are using it on what they have to do with it. Computer hardware companies are not responsible, you are putting the blame on a provider, it is the people that uses those hardware that should be responsible for their action. Chocolate is not the reason for diabetes, it is the sugar. If your main business model is to provide illegal substances, how can it be reasonable to compare it with legal businesses. We might not be on the same page here so sorry.

Point me to a source where it's proven that Ross Ulbricht actually sold drugs himself. Because as far as I know, he only created the platform where people sold drugs(the tool), not necessarily him selling the drugs himself; hence the knife/computer/chocolate indirect-effect analogy. I'm totally fine being wrong here.

"Ulbricht, a first-time offender, was not convicted of actually selling illegal drugs and other items himself, but of creating and operating a site where others did." https://www.investopedia.com/tech/ross-ulbricht-dark-net-pirate/
If memory serves me correctly, he grew and sold Mushrooms on the Silk Road platform in its very early days. It is difficult to say if this continued as it would have been trivial for him to create a sock puppet seller account.

He was not tried for the selling of Mushrooms, but I believe there is evidence he did so.

There is also the issue of the murder for hire plots that Ulbright allegedly paid for. Again, he wasn’t tried for this, and there may be entrapment issues with one of the plots, but it is a reason why I would be hesitant to pardon him.
2094  Bitcoin / Development & Technical Discussion / Re: Will there ever be any monetary incentives to run a full node? on: December 16, 2020, 08:20:52 PM
I was describing the risk to using a SPV client. Using a block explorer may be one way to mitigate that risk. However as ETF said, it is atypical for someone to check a block explorer if it doesn’t appear that anything is wrong.

to be fair checking a transaction on a centralized block explorer is still risky. you are not just nullifying your privacy you are also trusting that website to not have any issues or not be malicious. it may be malicious and give false information or it simply may be severely buggy, for example the explorer called blockchain.info (now changed to .com) has always been popular and has always been very buggy!
Using a block explorer in addition to a SPV client will incrementally increase security. If it is being buggy, it would give a false indication that you should not rely upon a transaction that the SPV client is saying was received. At worst, you would have the same security as relying on a SPV client alone.

You are correct in saying that using a block explorer may result in reduced privacy, but this is something you would need to weigh with the potential impact on security.
2095  Bitcoin / Development & Technical Discussion / Re: Will there ever be any monetary incentives to run a full node? on: December 16, 2020, 04:58:36 PM
If a SPV wallet doesn't implement checkpoints, it would theoretically be fairly easy to trick the SPV wallet by building an alternative chain. Since that chain is the only chain the client will see, it is assumed to be the longest valid chain. With a checkpoint system, the attacker will have to build the chain after the checkpoint which is significantly more difficult but will not require anywhere near 50% of the network's hashpower.

You see, the reason why 51% attack works is because it can generate valid blocks faster than the rest of the network. You don't need anywhere near 51% of the hashpower if you have all the time in the world. I can probably generate a block with enough POW in a few days if I purchase enough hashpower. I don't need to worry about someone else generating the block before me because the client won't be able to see it.

51% attack is about receiving coins on a wrong chain, not sending. So even if you will be able to isolate SPV wallet owner on a wrong chain how it will help to attack him?
It could trick them into believing they received coins via an invalid transaction.

Well, this is something very unlikely to happen. If we talk about regular user, transaction can be very easily checked on any block explorer which is hard to fake. Big players usually use more subtle tech than just SPV wallet/node.

2096  Other / Meta / Re: Messages signed from an address with a leaked private key on: December 16, 2020, 03:51:03 AM
Now everything is making sense to me.


Quote
When you try to sign a message using brainwallet, you will that address and its corresponding private key by default and you need to enter your own private key. These users simply didn't change the address, just wrote the message and clicked on "sign message" button.
Most probably these users did not have a clue what they were doing so really we can not question them. It was an innocent mistake from ignorance of course.  However, I was a bit suspicious before getting your point and checking the default link (LOL) https://brainwalletx.github.io/#sign

The address 1HZwkjkeaoZfTSaJxDw6aKkxp45agDiEzN has received over 59 btc over hundreds of transactions. It is unlikely that the 11 people are the only ones that have made this mistake.



To all admins and recovery team:
Please don't accept recovery appeals made using the address above.

This is hardly the only private key that is publicly known (I would disagree with the description of "leaked" to describe this private key) that presumably new users use. There is an argument to require any signing address have a nominal unspent output in order to accept the signature.

I also believe a signed message is only one data point the recovery team looks at when deciding if they will recover an account or not. I believe they also look at things like your ISP, browser fingerprint, and possibly some other things.
2097  Other / Politics & Society / Re: Bet PrimeNumber7 vs. DaveF on: December 16, 2020, 02:05:26 AM
So PrimeNumber7 paid early.


First, it was a pleasure working with you.

I paid early because I don’t see any realistic path for Trump to be president in 2021, and I think that Trump should acknowledge that Biden will be president (legitimate or otherwise) next year, and he can start his next Presidential campaign if he do chooses.

For the good of the country.

Why do that when you can just raise $200+M off of a totally bullshit cause and continue to maintain the grip of the party around yourself?

Highly doubt that Trump is going to concede normally, his twitter has been too crazy recently. He's told too much of the party that this is a scam and they fully believe him, around 70% of the GOP thinks there was election fraud.

Hopefully for the good of the country he does concede, because it is over.
Having a $200mm + war chest before he even leaves office gives him a huge advantage in the 2024 general election, and I doubt he will have serious competition in the primaries if he decides to run.

I didn't say that Trump should concede the election, I said he should acknowledge that Biden will be the next president. There were irregularities in multiple states, voting rules were changed without the state legislatures (despite the constitution requiring that state legislatures set voting rules), and rules were applied unevenly. This was why I made this bet with DaveF, as I thought that Trump had a pretty solid argument.

I think Trump's strategy was to make outlandish claims via proxies (Sydney Powell, and Rudy Giuliani) in order to get republican controlled state legislatures to send republican electoral college voters to the EC despite the results showing that Biden won their state's election. I think the problem was that the claims were too outlandish, and were not supported by facts. Trump's legal team never made a serious effort into having the courts address what I believe were serious deficiencies in the election. I think Trump was afraid the SC would be hesitant to throw out a deficient Presidential election on fairly minor issues, even though they were large enough to swing the election in Biden's favor.

Probably, if Trump doesn't activate the Insurrection Act, nobody else will do anything in a big way.

The time is near where Trump will have to activate the Insurrection Act, or otherwise forget it.
I don’t think the insurrection act will do much for trump. The military was not on Trumps side during the summer when there was riots and a legitimate need to invoke the insurrection act, or at least the top of the military was not on his side. Trump trying to use the military to stay in power is not going to end well for the US, and would probably not turn out well for Trump either.

Like, what the fuck is this even at this point. Why do people think that it's okay that Donald Trump is going to activate the Insurrection Act -- this man would literally be declaring martial law and and destroying the democracy that we've built to this point.


I don't think he'll do it, but if he does that's a truly horrible thing that should never be done. EVER.
I have not heard any elected Republican official, nor any official in the Republican party call for Trump to invoke the insurrection act. I also have not heard of any mainstream right-leaning person call for Trump to use the military to stay in power.

Obviously, there will always be people calling for rather extreme things to happen.

Quote
Conservatives for years yelled about Obama and how he was going to takeover American democracy to further his own interests. He NEVER declared martial law and he never attempted to takeover the country.
I would point out that Obama weaponized the IRS in the 2012 election season to harass right-leaning interest groups. The Obama administration also used/abused the FISA court to spy on an opposition party presidential campaign.

I would also point out that Clinton supporters had called for Trump's electrical college electors to vote for someone other than Trump in order to prevent him from becoming president.

Obama never declared martial law, but the record does show he acted corruptly in order to keep himself and his party in power.

Soldiers follow orders. They are taught to not question the ethics or reasons, or even to know them.

If the Insurrection Act is activated, it will be based on Trump's 2018 Executive Order. So, there will be enough proof for any military people who need it.

Cool
There are obviously limits to that principle. I don’t think Trump invoking the insurrection act is a good idea right now. I don’t see many options for him to challenge the results of the election.

I think Trump should acknowledge that Biden will be President in January (even if illegitimately) and start his 2024 campaign.
