1681  Bitcoin / Development & Technical Discussion / Re: How grab 100 daily transactions with details - Using an api on: April 16, 2021, 12:27:37 PM
How can i use mempool.space api for that purpose and grab 100 new confirmed or unconfirmed transactions with details?
You should review the documentation for their API. You should click on the "Transactions" tab.

If you are making 100 API calls every 5 minutes, you may run into rate limit issues and may get blocked. I don't see anything about rate limits, or the ability to buy a "premium" subscription to their API service that would allow you to make a higher volume of queries.

As others have mentioned, you can also create your own API (or hire someone to do so) that you can use to query this information.

I mean... so if someone accidentally puts down they want to sell 5 btc right now on coinbase pro and accidentally put the sell price at 500 dollars... what would happen?  Someone or the bots would immediately see this error and buy it immediately and profit?  But if its an obvious error, there is no protection for someone who makes a mistake with this?
If you place a limit order to sell your coin at a price below the best bid price, your order will be treated similar to a "market" order and will be matched against existing buy orders that are priced at or above your limit price, starting with the orders buying coin at the highest price.

When someone spends outputs that have a fraction of a satoshi, the transaction will appear to be invalid because it violates consensus rules. If you can send a fraction of a satoshi, you can also send 1.5 satoshi in an output.
Spending zero satoshi is backward-compatible. New amounts will be visible only by new clients, the old ones will see moving zero satoshis from some inputs to zero satoshis to some outputs. It is similar as in Segwit: if you run some old client, you see no signatures in Segwit inputs.
No. That is nonsense. If someone spent two 0.5 satoshi inputs and had a single output of 1 satoshi output, an old node would need to recognize the output as being valid

With SegWit, there were scripts that were previously "anyone can spend" that were changed to "only certain people can spend". This means transactions sent to SegWit addresses would appear valid to both old and new nodes, and that transactions that spend SegWit inputs would appear valid to both old and new nodes, but old nodes would not be able to validate if the transaction is valid under new rules.

A soft fork must restrict the transactions that are valid. Your proposal increases the transactions that are valid.

It's a good idea but a soft-fork is needed
The current consensus rules dictate that the smallest fraction of a bitcoin is one satoshi. The OP's proposal will only be needed if this consensus rule changes. In order to change a consensus rule, a hard fork will be necessary, therefore any fork involving the OPs proposal might as well be part of a hard fork.

The below-quoted post is an instance of nutildah telling a clear-cut, easily provable lie couched in the form of a rhetorical question, and using that lie to smear my reputation.

The post is missing from Loyce.Club:  Archive of Loyce.Club 404 error, archive of Loyce.Club topic list which does not show this post.  The post is available from Ninjastic.Space (archive of Ninjastic archive of post; archive of Ninjastic archive of the topic).  I have not (yet?) collated the list with other available records to ascertain if any other posts are missing.

For the record:  I did not delete any of ibminer’s posts from that topic.  I was manually fending off an apparent spambot attack by suchmoon, who reposted identical content 21 times within 2 hours; she sometimes reposted within seconds after I deleted it, so I rather doubt that that was done manually.  <>

Now, I must ask:  What happened to post ID 56749635 in the Loyce.Club archive?  Was it eaten by a bug, or was that post intentionally excluded for some reason?  —If this is a bug, how many other posts may be affected?

Loyce's bot will parse the forum's recent posts page only so often. If a post is deleted, my presumption is that the post will be removed from the recent posts page. This means if you delete a post shortly after a post is made, there is a chance anyone scraping forum posts will miss it.

You will want to put every transaction into a database, and run a database query anytime you want to lookup information about an address. This is in essence what any block explorer will do whenever you lookup an address or transaction.
1688  Bitcoin / Electrum / Re: What are the positives and negatives of leaving a lightning payment channel open on: April 11, 2021, 11:38:14 PM
What are the positives and negatives of leaving a lightning payment channel open? How am I contributing to the lightning network and what are the risks if any?
In Electrum? I think keeping it open will not contribute to the network since Electrum-made channels (trampoline or not) don't route payments (CMIIAW).

As nc50lc has said, channels founded using Electrum cannot be used for payment routing. All channels are private so they are not advertised across the network and cannot be found using Lightning explorers (ex. 1ml.com).
I think future versions of electrum should support the ability to route payments via LN. Without this feature, I can see a lot of LN nodes closing LN channels with electrum users if they do not use many transactions, especially if the electrum user has sent payments to/via the LN channel, meaning the LN node is tying up capacity.

More speculation: If you are reporting posts that are old when you report them, your report may not be high on the priority list.
If you doing that they can marked also as unhandled and maybe you will get a message from a Global Mod as i have done that when i started.
Depends also on what you reporting.
Reports that are "unhandled" are not marked as anything. Reports in "unhandled" status mean that no moderator has taken action on the post you have reported. This could mean the mods have not had time to review your report, or it could mean that some mods reviewed your report and were not sure if they should take action or not. It could also mean that responding to your report requires research that the mod does not have time to conduct.

You are not going to be notified if a mod is not sure if action should be taken or not.

There is still an Armory sub, and there hasn't been any commits to their public GitHub repo in over two years, and there are issues without discussion from over a year ago, making me believe the devs have all but abandoned the project.

It's not abandoned, check out other branches: https://github.com/goatpig/BitcoinArmory/branches/all, especially the development branch: https://github.com/goatpig/BitcoinArmory/commits/dev

Also: https://github.com/goatpig/BitcoinArmory/issues/657 It's just that only one person is working on it, probably with more important stuff on his mind day to day.
Ahh, you're right. It is interesting there would be so much activity on the dev branch, and no merges into production after so long.

The cost of keeping a sub open is low, and there are a lot of existing threads in both the Armory and Mycellium subs that people can search and review. The development of wallet software has improved over the years, and there are not the same amount of bugs there were five years ago, so users of wallet software largely don't have problems running the various wallet software.

Yes. Mycelium's popularity also stems from the fact that it was easy to use and 'just worked'. I found mobile Electrum to be very buggy when trying it out years ago.
I think the deterministic generation of addresses, the standardization of derivation paths, and of seeds has made it easier to develop wallet software and has made it not as big of a deal if there are problems with the software because the consumer's money will be safe as long as the software can calculate the addresses correctly.

The above principles are important if LN is going to be successful. LN wallet software needs to have a good mechanism for not losing the latest channel state, and associated transactions if it will be successful.

I’ve sometimes wondered why the 300 good report threshold must be met in order to gain access to the last 30 day report detail window. At some point I guessed it was a perk that had the threshold as an incentive, but it’s not really common knowledge, so the incentive theory doesn’t quite add-up.
This is speculation: Maybe the admins don't want someone who has not shown they know how to effectively report posts trying to question unhandled and bad reports.



Quite a lot of my reports have been threads where one user has posted multiple times (usually five or less minutes apart) - at a guess, the admin/mods have looked at the sheer numbers reported and decided not to bother.
More speculation: If you are reporting posts that are old when you report them, your report may not be high on the priority list.


1692  Economy / Exchanges / Re: Coinbase vs Coinbase Pro Question on: April 11, 2021, 07:28:15 AM

Now... what im confused is when i log into coinbase pro site... how come it shows my balance as 0?  It doesn't seem to show any btc i have?


I have a very tiny amount of btc, bch and btg when i check my coinbase account... my usd balance is 0 of course.  But how come i don't see any btc, bch or btg balance on coinbase pro?  Shouldn't they be linked?  Or i need to send the btc/bch/btg from coinbase to coinbase pro? 
You have to transfer any USD or coin you have in your coinbase account to your coinbase pro account. Also note that you will have withdrawal limits as to how much you are able to withdraw from your coinbase pro account per day, and if you have coin valued above these limits, you will have to process withdrawals over multiple days.


If that is the case, wouldn't it make sense if someone wants to trade 50k or l00k worth of btc or more... to always be the maker?  I mean...i know if you are the taker... you can just accept the offer just like that.  But how much longer are you really waiting for you are the maker?  Can't be that long right?
If you are in the process of buying coin, if you try to be the maker, you may have to continuously revise your price upwards until someone sells into your order, possibly by an amount that is greater than the fee savings verses if you had placed a taker order. There is no guarantee the price will ever be a better price in your favor than what it is at the time you place your oder.



Also when using coinbase pro, you are doing trades with other users.  With coinbase, you are buying/selling directly from coinbase right?
My understanding is that when you buy on coinbase, they will send your order to coinbase pro as a market order. Some of their fee is exchange rate risk because they may quote a price at x time, and the price goes against them by the time you press the button to have the order execute on coinbase.

So to give a better perspective, 25 threads over 13+ weeks this year compared with 11 threads in Mycelium's dedicated child-board over the same period of time.

What about the Mycelium section then? There doesn't seem to be much activity and yet it exists. Was there any particular reason why it was created?

I don't know what's the current popularity ranking of Bitcoin wallets, or mobile Bitcoin wallets, but at one point (~2013-2016) Mycelium was the most popular mobile Bitcoin wallet, and a very popular one altogether even when compared with desktop wallets. There are more wallets now, a lot of people use exchanges as wallets anyway, and bitcointalk also competes for attention with other Internet venues, so all of these factors influence why that section isn't very active.

Sadly, I don't see Biden doing anything about further action by Russia against Ukraine. If you are currently in the Ukraine, I would recommend that you seek refuge.

That’s a good point, but does that mean that most/the majority of the community during 2017, that included users, exchanges, merchants, within the Bitcoin network were against Segwit? Or there was a chance they didn’t support it? I believe not.

I believe a lot of the bitcoin ecosystem did not initially support SegWit. I think it is difficult to argue otherwise. Over time, arguments were made in favor of SegWit, including the various failures of alternate scaling implementations, and the signaling of various futures markets.

In other words, over time, minds were changed after additional data was understood. This is exactly how bitcoin should be improved. A BIP can be proposed that has initial opposition, and those in favor of the BIP should make a compelling argument as to why others should support the BIP.


That’s what I said.

The UASF was starting to pick up, with some developers, and exchanges beginning to support it, that’s why the miners only started to agree with the update. Without UASF, they would have continued to hold the network hostage.


But you replied that it was only speculation, https://bitcointalk.org/index.php?topic=5140134.msg56707724#msg56707724

The UASF, and its other forms in the future will never be something “bad”, in fact, I believe it’s required to counter-balance governance issues.
USAF is a strong-arm tactic, it is coercion. That is not what I was referring to. I was referring to the proponents of SegWit 'selling' the benefits of SegWit to bitcoin's various stakeholders using persuasion. 
1696  Bitcoin / Bitcoin Technical Support / Re: Full Bitcoin Node Costs on: April 10, 2021, 05:53:31 AM
Regular light bulbs don't run 24/7 and LED lights have been a thing for a while now with markedly lower power consumption.

Let's say someone decides to repurpose their older computer that uses 50 watts when a Bitcoin full node is running. 0.05 kW * 24 * 30 * 12 = 432 kW per year. In Germany or Denmark, for example (countries with expensive electricity), that's going to amount to over $150 per year.

So you are comparing OLD computer hardware with new led light bulbs?

Computers have a very long useful life, while lightbulbs need to be frequently replaced. Some electric companies will also give away x LED lightbulbs for free to new customers to help reduce total electric consumption.

If someone has an old, power-hungry computer to run a full node, that is all that is available without incurring additional costs.

People will go also crazy buying Crypto after they buy coinbase shares,
I doubt it. Coinbase is just another company among thousands that are selling shares on stock market. Companies with more stable situation and a longer history that stock market investors prefer over a company they have never heard of working with something (bitcoin) they also may not even have heard of or worse heard and believed some FUD about it!
Coinbase going public is a major milestone for bitcoin. It is the first major crypto-related company to truly go public. Holding a share of coinbase is not he same as holding bitcoin, however it is a metric as to the market's confidence in bitcoin's long term success.

You are confusing Coinbase with Binance.
BNB is a centralized shitcoin created by Binance and is pumped and dumped by them which has nothing to do with Coinbase.
BNB is a centralized token-coin created by Binance, not by coinbase. BNB provides utility to binance customers by allowing them to pay lower fees while using the binance exchange. I would not say that BNB is as worthless, nor pointless as the majority of altcoins out there.

His testimony <> speculates that Chauvin used 90 pounds and exerted it onto Floyd's neck. Dr. Tobin openly admits he used a still picture to arrive at this figure. Obviously I don't need to explain why this has all sorts of issues.

The defense should have objected to this answer. The same is true for any conclusions Dr. Tobin made. I expect Chauvin to mount a defense that includes their own expert witnesses.

What I don't understand is how either of you can believe you actually possess more knowledge about this issue than the experts and attorneys in the courtroom. The normalization of the questioning of experts when people don't like what they have to say will be one of Trump's longest lasting legacies.
There is no way Dr. Tobin would be able to know how much weight Chauvin put on Floyd's neck with his knee. The figure he gave was a guess.

If one of your feet (or knee) were hurt, you would probably lean on your other foot while standing, so that the hurt foot has very little pressure and the "good" foot has most of your body weight on it. The same principle applies to how much pressure Chauvin was putting on Floyd's body with his knee.


Dr. Baker testified today, he said what we knew from the autopsy report -

Floyd died from fighting with police, subdual, and neck compression with contributing factors of drug use and underlying heart conditions.
I think this is what is going to cause the reasonable doubt:
“Absent suspicious circumstances, if Floyd had been found dead in his bed with the level of fentanyl in his blood that was present for this autopsy, it may be classified a fentanyl fatality,”

Dr Baker's testimony is basically that Floyd died from the actions of another person solely because of what he saw on the video, despite evidence to the contrary.

In 2017, there were many "futures" markets that allowed market participants to price the value of various fork-coins, and the owners of mining equipment ("hashers") likely saw that mining on the NYA/BTC1 would not be in their best interest.
It wasn't because of the futures fake markets but because they saw that going ahead with the hard fork part of SegWit2x would split bitcoin and it was not in their best interest. Believe it or not miners have a bigger stake in bitcoin since they both invest in equipment and bitcoin at the same time. Unlike nodes ore regular users who many not even own any bitcoin (anything at stake).

~ a good next step would be to encourage reputable exchanges to open futures markets for both "for" and "against" forks for a BIP, and hope that the result will change minds.
Proposals should be discussed and then approved/rejected based on their merits not based on what the
market (day traders who only care about their short term profit) think. Keep in mind that it is very easy to manipulate the market price on a centralized exchange specially when not enough people turn to that option.
Wells I guess I would ask how would one know if something is in the best interest of bitcoin? I could give my opinion based on my own expertise, but doing something because an "expert" says so is anti-thetical to bitcoin. If an exchange is reputable (or even better, if multiple exchanges are reputable), and are neutrally offering a particular market, the ecosystem can take the information into consideration. This is especially true if reputable exchanges allow for holders of bitcoin.current_implementation to exchange into BIPxxx.yes and BIPxxx.no and vice versa, to allow for arbitrage.

As I previously stated, the miners are the only entity that cannot fake their level of support. It is trivial to run an arbitrary number of fakes nodes,

The point you're trying to make is a valid one, but your expression of it isn't technically correct.  Miners can easily fake their 'support' for any flag, and they often have in the past-- e.g. signaling BTC1 when they weren't running it and had zero intention of ever running it.
I suspect major mining pools are running their own custom implementations of bitcoin for broadcasting, receiving, and validating blocks. 

In 2017, there were many "futures" markets that allowed market participants to price the value of various fork-coins, and the owners of mining equipment ("hashers") likely saw that mining on the NYA/BTC1 would not be in their best interest.

So while it's true that miner signaling is sybil resistant,  the mining pools signaling flags don't necessarily have much skin in what they signal, so fairly little incentive to do so honestly.  This is particularly true because the parties with an investment in hardware are hashers (whom don't control the flags) and not pools (who do control the flags. 
The mining pools earn income from the blocks they mine, and they need to invest in infrastructure to allow their pool to operate. If a pool has fewer hashers, it will have less income. It is also trivial for hashers to move their miners to pools that are signaling for or against a proposal that is in line with the long-term best interest of bitcoin. If a pool is signaling for or against a proposal that is not in bitcoins best interest, it will lose customers.


Many pools have significant altcoin investments and it's not too hard to imagine a kickback or altcoin play making fake signaling in a pool's interest.  Even hashers can move hashpower to altcoins that might gain value if Bitcoin had issues.
I would have to disagree with the bolded part of your statement. The altcoins that can be mined using ASIC miners that can also mine bitcoin have a very low network hashrate as a function of the hashrate of the bitcoin network. If 1% of the hashers (measured by hashrate) currently mining bitcoin were to move to bitcoin cash, the difficulty would more than double, which means the price of bitcoin cash would need to more than double for the hashers to have the same amount of revenue. This is simply not something that will scale for enough hashers to oppose a bitcoin proposal whose failure would benefit bcash. Even if it did scale, once these hashers start mining bcash, any proposal whose failure would benefit bcash could subsequently be implemented.

The real unfakable metric is the eventual market price of the asset -- but we can't know that in advance, only make educated guesses.
I mentioned futures markets for various fork-coins above. Any futures market would need to either be centralized, or run on an altcoin blockchain, such as etherum in order to be reliable.

My position continues to be that it is best to get miners' consent prior to implementing a fork (soft or hard). If there is a BIP proposal that is receiving pushback from the miners (based on what they are signaling), or if the miners are signaling support for a "bad" BIP proposal, a good next step would be to encourage reputable exchanges to open futures markets for both "for" and "against" forks for a BIP, and hope that the result will change minds.
