But, voting should be anonymous.
This. Without the secret ballot, it would be possible for governments to intimidate people into voting a certain way. This is why "cardcheck" voting for union votes are so bad (and why unions are so in favor of it).


Another issue is that it is trivial to create an ~unlimited number of private keys. A blockchain vote could prove that a candidate received a certain number of votes, but it would be impossible to know if only eligible voters cast votes.

When the pandemic started, China wasn't that paranoid about new infections, what changed now?

They locked down Wuhan early on. Foreign travel was severely restricted. I don't think anything really changed, they always had the intent to contain it completely.

New mutation or not, it's not sensible to have such strict measures, when the rest of the Western world is easing measures.

I can't argue that it's sensible - most of the actions of the Chinese government don't make sense to me, and starving their citizens is definitely one of those things.

But the immunity levels are most likely very different between China and the West where almost everyone had some strain of COVID.
Certainly, they did have strict policies since the beginning, but I don't recall seeing such action taken against their citizens. They've literally locked them up, with no access to anywhere, while the government is distributing food that to me, doesn't look enough for a household.
In early 2020, Chinese citizens were locked inside their apartments, and people starved to death. The "lockdowns" employed by the West was something exported from China. Prior to covid, "lockdowns" were not considered to be something health officials considered to prevent the spread of contagious viruses.
Quote
Certainly, they didn't have as many infections as Europe and USA, but it looks incredibly cruel to see such practices.
China did not report having as many infections as Western countries did. The Chinese government also lies. I draw different conclusions than you.

BlueWallet says: "Unsupported lnurl".
Phoenix Wallet can't scan the QR-code. Copying it manually shows "legend.lnbits.com returned an error".
Muun Wallet says: "Contacting legend.lnbits.com...", followed by "Something went wrong".
That's not the best promotion for LN Sad
To continue this test: I just found out that 3 days ago, my BlueWallet received 2 times 2100 sat. So it looks like the failed and "Unsupported lnurl" worked a bit later anyway! I can't check if Muun Wallet received something, because I already deleted it (and the seed phrase too).

I assumed a LNURL payment can work only once, but somehow the same QR-code paid me 3 times in total. That seems like a serious bug. I'll donate it back again.
It is only a matter of time before someone takes all the coin intended to be offered to MuunWallet users. The process you described already sounds easy to automate at scale, and simply accessing a LNURL is even easier.

And I didn't get anything in any of the wallets I tried.
I guess either they did some really bad coding, or did not put in enough funds, or???
Either way, does not make them look good.

-Dave
Loyce's experience with the error messages is likely (IMO) a result of poor coding and/or the lack of testing (and resolving issues when tests fail). If you are not receiving any funds when Loyce received funds 3x, may mean that someone already took all the funds.

The topics that were created in one board and then moved into another board do not have any updated information about the new board they have been moved to.
It's almost impossible to do that.
In order to have information about the new location of the posts, TryNinja has to scrap the location of all the posts made in the forum again and again forever.
There are two ways this could be done.

1 - When a new post is made, the post will show which section the subject thread is located in. If a new post is made in an existing thread, the location of the thread can be updated.

2 - When a thread on your watchlist is moved, it will show up on your watchlist again, even if there are no new posts. TryNinja could theoretically add every thread to his watchlist and monitor for the thread's location being changed, although this is probably less feasible than the above.

I don't even seen any offer which is 1% off the market price. Some are even over 10% off
That means, even if you are not paying high fees, they are already earning because of the expensive rates they are offering.
Then don't accept those rates - such is the beauty of trading on a DEX. If you use Coinbase, you get whatever rates they give you. If you use something like Bisq or LocalCryptos, then if you don't see an offer you like, you can create your own. Even better, you can swing the rates the other way so they are in your favor. If you are willing to have a little bit of patience and be a maker rather than a taker, you can end up netting a few extra percent on your trade, which is more than enough to cover all your fees and make you a little extra profit too.
Pretty much every exchange allows users to place limit orders.

I would also not describe the price on coinbase as the "price it gives" the customer. I think it would be more accurate to say the price is based on the market participants on the coinbase pro exchange. In general, liquidity on DEX's are lower than that of major exchanges, which will generally allow for better pricing on the major exchange than on a DEX.

When miners are mining via Bitcoin's PoW protocol, they are generating random numbers, passing each of those random numbers through a hash algorithm,...
They don't generate random numbers. What they do is increment a nonce which alters the data set of a block producing a different hash.
Increasing the nonce effectively produces a random number. What I said is a very simplified explanation of what happens.

Quote
...and when the output of the hash algorithm is below a target, the miner will broadcast their found block. The output of the hash algorithm is effectively random, so with a given target, the expected number of "guesses" will be the same regardless of if one person is working on the block, or a billion people are working on the block.
In other words, every block has a range of hash values that it will produce as the nonce is incremented, and the first value in that range that satisfies the size requirement of the difficulty level exists at a specific height in that range and therefore requires that much work to reach regardless of whether it's one miner working solo or a whole pool.  That's all true, I never argued otherwise, but none of it supports your assertion that what I said is false.
Yes, it does. The expected number of hashes required to find a block is the same regardless of if one miner is trying to find a block or a million miners are trying to find a block.

If a nonce, x results in a valid block, nonce x + 1 will not necessarily also find a valid block.

Quote
There might be an argument that some work is waisted when two miners find a block at approximately the same time,...
This causes a soft fork in which the leading end of the blockchain splits into two or more chains.  It gets resolved when one of the chains gets longer than the others. When that happens, all the work that was spent solving the blocks in the discarded chain is wasted.  This is in addition to the waste that I bought up in my OP which is only about the energy wasted in each round by solo miners who fail to solve their blocks first.  And, after all these words, you still haven't proven how this is false.
I disagree with your terminology.

When there are two competing blocks, block x, the work spent trying to find block x + 1 is duplicated. However, as I mentioned, this has happened approximately 1% of the time int he past, and is likely lower now. There is no other duplication of work.

Sure, if you compare it with last year but since the beginning of the year, the number of nodes and channels didn't increase significantly. Only the network capacity increases a bit
https://charts.woobull.com/bitcoin-lightning-network/
https://bitcoinvisuals.com/lightning
According to the graphs you cite, the number of nodes and channels has more than doubled over the past year. 100% YoY growth is pretty good.

Also, not all nodes will necessarily be known to the public, especially if a node is only connected to one other node. Some of LN usage is going to be via custodial services, such as BlueWallet, and I would consider this as increased adoption.
529  Bitcoin / Development & Technical Discussion / Re: Can a Checksum be used to recover a forgotten data? on: April 17, 2022, 08:30:54 AM
2. Can Checksums be used to recover a forgotten data?     How?
No. A checksum is used to help you quickly determine if a value is valid or not. It is not possible to go from the checksum to the original data (just as it is not possible to go from the hash of data to the original data).

The only way a checksum could potentially help you recover data is if you stored many versions of data, but a particular checksum would only validate one of these versions. This would allow you to quickly determine which version of your data is valid. However, for every checksum, there are an infinite number of potential data that has a given checksum. So using a checksum to recover your data is useless unless you have a limited number of data candidates.
530  Other / Meta / Re: Monthly Report Statistics on: April 17, 2022, 08:24:19 AM
There's nothing to see here, it's just that the amount of monthly reports coming in is much more than what the active mods can handle because most of the cases are handled manually, they're not bots I never expected them to handle all monthly reported cases, most of my last month reports were left unhandled I guess mod didn't pick it up

This is hardly the true reason for so many unhandled.
It really depends on when the reports were made, and when the cutoff for the reporting period was. For example, if someone happened to make many reports shortly before the reporting cutoff, it is possible that the mods simply had not yet had time to handle the reports.

A useful piece of additional context would be of the ~1700 unhandled reports, how many were handled as of 48 hours after the reporting period ended.

Requiring customers to withdraw their coin will lead to higher costs in the form of transaction fees, and will likely result in transaction fees increasing if the exchange is large enough.
Exchanges already make huge profits on withdrawal fees. Binance charges 50,000 sats per withdrawal when 500 sats would more than cover it, and then pockets the difference. More withdrawals would result in more profits from fees for Binance, not less. But as you say, forcing customers to keep coins on the exchange leads to more profits from trading fees.

I think it is most likely that exchanges stand to lose more in trading fees than they do in additional transaction fee revenue if they required their customers to withdraw their coin immediately after trading. I don't think transaction fee revenue is as much as a revenue center as it is a way to discourage smaller accounts.

If someone with $20,000 worth of coin is forced to immediately withdraw, if this results in this customer from making a single trade, this type of policy would be a net negative from a profit perspective.

Another negative is that this policy would effectively make it impossible for an exchange to store customer money in cold storage. Currently, if a malicious actor were to compromise the trading engine, and say for example crash the price down to $0.01, the exchange could simply reverse the trades, and take the hit for whatever was in their hot wallet. If customers had to withdraw, anyone holding USD would likely be left holding the bag.
532  Bitcoin / Hardware wallets / Re: Trezor mailing list breached on: April 17, 2022, 07:47:49 AM
Today I heard news for one more Mailchimp exploit related with Bitmex exchange, so it's not only Trezor wallet newsletter that is affected.
This is just confirmation of my suspicions that more exchanges are using Mailchimp and similar services.
Bitmex claims that no sensitive information was leaked, but people should expect to receive phishing email soon, so better get ready.
Appearently Mailchimp has a decent number of crypto-related companies as their customers.

Mailchimp is likely to only have a list of email addresses, and at most your name (although this could be limited to your first or last name and gender). Obviously, the fact that you are likely a customer of a particular company was also leaked, which allows the hacker to send phishing emails.
533  Economy / Service Discussion / Re: Robinhood to enable the lightning network on: April 17, 2022, 07:19:49 AM
Sounds great. Isn't Robinhood traders the kind of people who just leave funds on the platform though? Not necessarily the people who buy bitcoin and withdraw them to a non-custodial wallet?

Regardless, even if I don't think it would be used on Robinhood that much, I hope this move pressures exchanges to follow suit.
I mean its hard to measure that accurately, without just being stereotypical. Honestly, I believe any self respecting exchange should require you to transfer the funds to another address that the user owns, I don't like the idea of having a wallet on an exchange, you're just asking for trouble. I'd have an insane amount of respect for any exchange that would build that into the process. Since, that tells me they actually care about the safety of their customers, and not encouraging bad habits. Of course, they won't since the more people they get on their website, the more money they earn since even being on the website probably gives users the temptation to trade.

Same goes for Robinhood, I'd like to see them dropping support for keeping funds on their website, rather than implementing features to better it.
I don't see any centralized exchange ever doing this. Requiring customers to withdraw their coin will lead to higher costs in the form of transaction fees, and will likely result in transaction fees increasing if the exchange is large enough.

Allowing customers to keep their coin on an exchange will also make their account more "sticky" as their customers will have to do more to move their money elsewhere. Further, allowing customers to keep their money on an exchange makes it easier for their customers to trade, which leads to both more liquidity, and to higher trading fees.

There are just too many incentives for Robinhood, or any other exchange to implement something similar to what you propose.
534  Other / New forum software / Re: 2FA - authentication on: April 17, 2022, 07:11:26 AM
That wouldn't eliminate the need for manual recoveries; it might even increase it as people lose their second factor. 2FA would be nice, but IMO the email notifications provide many of the same benefits, so it's not high on my to-do list.
This is the reason why I think it is unlikely for 2FA to ever be implemented on bitcointalk.

There is a lot of commerce that takes place on bitcointalk, however, a bitcointalk account is intended to be used for discussion. So the types of verifications that 2FA provides is better done when trading, rather than when logging in. There are sometimes occasions in which someone will legitimately lose access to their private keys, and the market can decide how to handle these situations, which will typically be that the person will need to earn trust subsequent to losing their private keys.

If 2FA is required to even log in, there will be instances in which the administration will be faced with the choice between not allowing someone who has evidence they are a long-standing forum member from accessing their account and potentially allowing an imported from accessing a long-standing forum member's account.
535  Bitcoin / Development & Technical Discussion / Re: How to reduce energy consumption and eliminate wasted work on: April 17, 2022, 06:39:21 AM
The vast majority of the energy spent on mining Bitcoin is wasted through the competitive aspect of it's POW protocol.  Miners compete by doing the same work in parallel but it's only the miners who win whose work counts, the rest is wasted.  
This is false.

When miners are mining via Bitcoin's PoW protocol, they are generating random numbers, passing each of those random numbers through a hash algorithm, and when the output of the hash algorithm is below a target, the miner will broadcast their found block. The output of the hash algorithm is effectively random, so with a given target, the expected number of "guesses" will be the same regardless of if one person is working on the block, or a billion people are working on the block.

There might be an argument that some work is waisted when two miners find a block at approximately the same time, however reducing the number of miners mining at once will not address this issue as most mining entities are going to be using multiple computers at once to try to find a block. I am not sure of how frequently this happens, but I understand that in the past it had occurred approximately 1% of the time, and this has likely gone down.

So reducing wasted work theoretically has an upper bound potential to reduce the amount of electricity consumed via bitcoin PoW by 1%.
536  Other / Meta / Re: Bitcointalk sell 10 ads or 9? on: April 17, 2022, 05:24:58 AM
It is generally a good business practice to have a little extra capacity than what you actually plan on utilizing in case someone wants to purchase extra (in this case, ad space). Doing so will keep your customers happy when you can sell to them, will prevent them from looking elsewhere (in this case to advertise), and will allow you to sell at a premium.
537  Economy / Exchanges / Re: Another reason to avoid CEX for buying Bitcoin on: April 14, 2022, 01:56:27 PM
The $73 works out to about 1.4%, and the trader presumably got the market rate/price. On a DEX, there is a fee to the DEX plus the potential for the price to not be in your favor.

When trading, it is best to consider both the total fees, and the price you will get when compared to other mainstream markets.

No, that is unlikely. N0nce has less than 2k merit, and o_e_l_e_o and theymos both need less than 500 merit to reach 10k. I think it is most likely that one of them will reach 10k within a month.
539  Other / Meta / Re: The 200 with most earned merit. on: April 12, 2022, 08:58:54 AM
At some point, amounts and ranks don't matter that much anymore... At least, that's how it was in my case.

Sure, i still like to receive some merits, because it means somebody appreciates what i've written, but wether it's 5 merits or just 1 isn't that important. At some point, merits become less of a tool to rank up, and more of a thumbs-up functionality. I know it wasn't created for this purpose, but still, once you reach the legendary rank, that's a bit how it feels for me personally.
There becomes a point in which the amount of merit you receive is solely a function of how much you post. There are several forum members that will generally receive merit for a good percentage of their posts, and their merit is based on how many they write. I occasionally will receive merit for posts that are older, but the majority of merit I receive is received within a week or so of when I write the post.

I would say the above probably applies to most of those in the top 200 of earned merit.

Yeah My older pre merit posts would have been worth 2000 to 3000 merits. Over the 1000 they gave.

So the 1000 given to me was an undercount.

I figure if we always gave merits I would be at 6800-7800 not 4700-4800


And yes when people see my posts they know I effort to give good info and an occasional joke. They know I do not have a signature so I don't post for coins. That helps me get merits fairly quickly.

I likely made 50,000 posts as I deleted a lot of older posts  as many seem point less now.
My guess is that your older posts received more merit when the merit system was initially introduced, and over time the ratio of merit received for recent posts to merit received for older posts increased.

If you have been deleting posts over time, given your high post count, if the merit system had been introduced a month before you created your account, you would likely have substantially more merit than you have today, well above your 7800 estimate.

I like receiving merit as it shows that others appreciate my posts. Having additional merit gives you potentially more weight in the trust system because you are able to "vote" for more users to be eligible for DT1.

What was changed/edited?



I would add that plagiarism often results in posts that make little sense in the context of the subject conversation.

The above is important because copying the above ASICII art into a bitcointalk post would be illogical as this is not ebay. This is a subtle, but important detail. If you were to post this ASICII art in a sales thread (for example), it would raise more questions than the post would answer.

Disregarding the plagiarism question, I think saying that you traded on eBay when a seller says they will only sell via the forum, without additional context/information, may rise to being off-topic.

I would also point out that the person who sent these eBay feedbacks likely did so in order to attract attention to his own eBay store. Almost as a means of free advertising. Given your already high profile status as a trader, and your existing reputation, I think using something similar to what is referenced in the OP is not a good use of your time from a business perspective.
