I'm wondering if the code used to generate that address on the fly for the current user is open source(php code I guess?). It seems quite useful since it creates a new address per each user, and also apparently it executes some action whenever the payment is made. It seems to be a simple Bitcoin checkout, which could be great in certain use cases.
You want to use this code for some other forum or what? I don't think this feature needs to be open source and inspected by everyone, even if forum software is open source it can probably use other extensions with closed source code. It's not like members are sending millions of Bitcoins every day for copper membership, it's more like symbolic amount, currently that is around 0.00080198 BTC or $24. I was just curious to see how it was made because it seemed like a nice lite Bitcoin checkout for websites. But as I mentioned before, it's probably tied with the forum so it would be better to use any other library. And also I agree with you, I think there's no need for this to be open sourced. |

Hello
Does anyone know the proper command for attaching 2 USB board Apollo BTC devices to an Ubuntu linux machine?
Would it look something like this with both "/dev/ttyACM0 /dev/ttyACM1" being the devices connected to PC?
apollo-miner -host "*.pool.org" -port 3333 -user "wallet_address".Apollo -pswd x -comport /dev/ttyACM0 /dev/ttyACM1 -brd_ocp 75 -osc 50 -ao_mode 1
It looks like the miner software only can control one miner at a time, so you would need to execute two instances of it. Here's what the official script does: #!/bin/bash
#This Script finds all your connected Apollo BTC Standard Hashboards and starts each one with the settings below in a screen session. Please see the miner_start.sh file for additional directions.
start_hashboards()
{
while [ $1 ];
do
screen -dmS miner ./futurebit-miner -comport $1 -ao_mode 1 $settings
sleep 1
shift
done
}
#find and start external hashboards
ports=$(ls /dev/ttyACM*)
start_hashboards $ports
echo "Started"
You could either do that, or simply run them manually, based on your command it would be something like this: screen -dmS miner0 apollo-miner -host "*.pool.org" -port 3333 -user "wallet_address".Apollo -pswd x -comport /dev/ttyACM0 -brd_ocp 75 -osc 50 -ao_mode 1
sleep 1
screen -dmS miner1 apollo-miner -host "*.pool.org" -port 3333 -user "wallet_address".Apollo -pswd x -comport /dev/ttyACM1 -brd_ocp 75 -osc 50 -ao_mode 1
You can then do screen -r miner0 to go back to see the output of miner0. Same for miner1. To go back from that view, you can press Ctrl-A, then Ctrl-D. You can see what's running with screen -list |

Using something like BTCPayServer is ideal as it's open source, there are no fees, it supports lightning (and NFC!) and you don't need to rely on any middlemen. The only issue is that you have to deal with the configuration, and ongoing maintenance of the server/nodes. This is fine in certain use cases, but I'm curious about what is being offered these days as an alternative. The main requirement I have for this proof of concept is to be able to receive payments through lightning in a website on demand when someone interacts with it somehow, let's say they click a button that says Pay Now, they pay with lightning, an action is executed when funds are transferred, and I receive the payment at my wallet(which will be custodial of course). I'm expecting to have certain limitations and/or required to pay a fee for such a service. Bonus points for being Bitcoin only. Here's what I've found so far, happy to hear other alternatives or opinions about these services as I haven't used them so I don't know how good or bad they are: lnpay:This seems to be one of the best services as it's focused on lightning only, has a nice interface/api, and seems to work great. The free tier seems good to test it out, but having to pay $99 a month independent of how much I use it seems to defeat the purpose. It's probably great for a dedicated business, but seems a bit too much for just a fun project on the side.  Coinbase Commerce API: They are a big player so there's a lot of support and third party tools. Also, this is a fee that I would be more comfortable to pay as it's free until I get paid. But it looks like they don't support lightning payments(instead they support many alts), so this option is out.  Coingate:They seem to be similar to Coinbase, with also a 1% fee, but they do offer lightning at checkout. It does feel a bit bloated with all the alts, but it might be an option.  CoinCornerCoinCorner also charges 1% per transaction, they have lightning, and they don't have any alts!. This seems like a great option as they offer free unlimited withdrawals with lightning.  OpenNodeOpenNode supports lightning, they are Bitcoin only, and offer free scheduled withdrawals to on-chain addresses and free lightning withdrawals on-demand!. This seems too good to be true, not sure where they would be making any money. They do charge 1% for on-demand on-chain withdrawals, but I could easily just use lightning or the scheduled option. They only seem to charge a fee when converting to fiat, but maybe I'm missing something since if I'm not planning to do that, then the service would be free.  So, after reviewing these options it seems that either OpenNode or CoinCorner are the best ones that I've found so far. If anyone has any other option, has used any of them, or they can confirm that OpenNode indeed doesn't have any fees for Bitcoin only transactions, feel free to share it here. |

He definitely could and had been buying pizza with fiat all the time. Laszlo offered to buy pizzas for Bitcoin because it had never been done before.
Are you sure? How did Laszlo Hanyecz know that no one had done this before? How can we know that Laszlo Hanyecz was the first to exchange bitcoin for real goods? Yes, perhaps he was the first to make a public offer, but there could have been thousands of private deals before Laszlo in which bitcoin was broadly involved. Although bitcoin didn't yet have an "official" price set by the market, it still could have been used in the barter economy among those who understood bitcoin should have some value because of its peculiarities. Perhaps, people, who really believed in bitcoin when it had no market price, didn't want to announce they were participating in the bitcoin economy because they valued their privacy, which is why we have never heard of them. But we definitely have heard of Laszlo who has a public profile and is registered under his real name. If Satoshi Nakamoto, a mysterious creator of Bitcoin, has said he just exchanged his bitcoin for pizza, would you believe him? I doubt it since there is no way to verify that. But in the case of Laszlo, it is a lot easier to verify he had bought something because everything about him is public information. What you say is correct. Usually people refer to the first occurrence of something based on the first public occurrence of that thing. It could have happened before, but no one knows. If suddenly some evidence appears that someone else bought something with Bitcoin before Laszlo, then the public record would be updated to point to that transaction as the first. You could easily verify that Satoshi bought a pizza, you would only need to have a signed message with the address that paid for it. |

Bitcoin is open source, lots of address generator library using different programming language are open source too.
Probably theymos uses open source software to do the address generation of every user, but since this forum is not open source, then there's no way theymos will make the code for the copper membership open source too.
This forum is open source though, it's based on Simple Machines Forums, which is released under BSD: https://www.simplemachines.org/about/license.phpThinking about it though, you're right, it would probably be easier to just use a library as you mention instead of trying to re-use this solution. |

In the page where you can buy a Copper Membership it says: We are commonly asked how we know that you sent a payment. The address above was newly generated just for you, so when any BTC is sent to it, we will know to credit it to your account. It is all automatic.
I'm wondering if the code used to generate that address on the fly for the current user is open source(php code I guess?). It seems quite useful since it creates a new address per each user, and also apparently it executes some action whenever the payment is made. It seems to be a simple Bitcoin checkout, which could be great in certain use cases. It's fine if it's not open source, but it would be great to know if it is. |

Real Madrid will be staying at fancy, £2,150-a-night hotel in Paris, Auberge du Jeu de Paume, before the final against Liverpool...  I wonder if that's going to motivate them to play better to keep this level of benefits, or if they're just going to be so spoilt that they're not going to give 100% of it in the field. It will definitely be an interesting game to watch. |

Lazslo wrote the following soon after: This is an open offer by the way.. I will trade 10,000 BTC for 2 of these pizzas any time as long as I have the funds (I usually have plenty). If anyone is interested please let me know.
You think the offer is still valid? I'll even throw in extra cheese and stuffed crust. At the time that was a pretty convenient offer, because you could basically buy Bitcoins with a credit card. It was very difficult to buy Bitcoin around 2010. |

Therefore, if Laszlo Hanyecz had been a rational actor, he would have bought his pizza for fiat currency, not precious Bitcoin. Either he didn't believe Bitcoin had the potential to transform into something more valuable than government-printed paper, or he had some other motives to spend Bitcoin. We never know that. Either way, his example clearly showed the world that "magic internet currency" is really what it claims to be: a decentralized digital means to facilitate exchanges between two parties.
He definitely could and had been buying pizza with fiat all the time. Laszlo offered to buy pizzas for Bitcoin because it had never been done before. I just think it would be interesting if I could say that I paid for a pizza in bitcoins  Here are some photos of the original bitcoin pizza: http://web.archive.org/web/20180524011500/http://eclipse.heliacal.net/~solar/bitcoin/pizza/Of course he believed and still believes in Bitcoin, he was here from almost the beginning, he mined lots of bitcoins, published the source code of the first GPU miner, and continued to buy pizzas with bitcoin, he even bought more with lightning when that was new: I wanted to try out a real trade using lightning network. I don't know of any pizza places near me that accept lightning bitcoin yet but a friend from London agreed to do it and he sub contracted out the pizza delivery to a local shop.
In short, I paid bitcoin using the lightning network and he arranged for pizza to be delivered to me. In this trade my friend is just a middle man that is taking the risk on accepting lightning payments, but it demonstrates the basic premise of how this works for everyday transactions. It could just as well be the pizza shop accepting the payment directly with their own lightning node. Here are some photos of the lightning pizza: http://web.archive.org/web/20211102020332/eclipse.heliacal.net/~solar/bitcoin/lightning-pizza/ |

What will happen to Portugal after the Ronaldo era? Some of the other key players will be retiring soon (Rui Patrício, Pepe, José Fonte, João Moutinho.etc). It will be very difficult for Portugal to replace all these players and fill the vacuum. I have heard a lot about players such as Nuno Mendes and Gonçalo Ramos, but not sure whether they will be able to handle the pressure at top level. Anyway, for now let's wait and watch for their performance in Qatar 2022. Portugal is in a relatively easy group, along with Ghana, Uruguay and Korea. Qualifying for the next phase should be a cakewalk.
The fact that Pepe still plays and gets into the national team, by the way, is a more amazing achievement than, for example, the fact that Ibrahimovic is still playing. In the attack, it is more likely that the time depends on you when you have to strain and make a breakthrough, and in defense you are always led and even if there are no forces, but the enemy is attacking, you must give all your best at 200% and not take a break. And I must also say that despite the fact that a whole generation is leaving Portugal, young players are very promising and quite possibly will be a worthy replacement and will continue to fight for titles. Ibrahimovic playing at 40 is just insane. I would say Lewandowski, who kicked him out, at 33 is already at the older bracket, and this is probably going to be his last world cup with Poland. My guess is that a younger squad will get the cup this time. Still not sure which one, excited to see the start of the world cup, there has been so many covid delays! |

The best way to write a number of bitcoins is to use exactly 8 digits of precision, that way you can either think in terms of BTC or sats by just focusing on the left or right side of the number. Example: 0.12300000. Think in terms of BTC, so that's basically 0.123 BTC
0.00045678. Think in terms of sats, so that's basically 45,678 sats

Absolutely fantastic job handsome_latino and o_e_l_e_o! I recommend everyone to go and solve the puzzle(banks are not your friends), and read the message, it's actually quite an important and deep message that a lot of people don't realize. And well, the execution of the confetti was flawless as well  So glad to be part of a community with people so talented. |

After reading about the Bolt Card, which is basically an NFC card with an LNURL-Withdraw link stored in it, I'm wondering if it would be possible to mass produce coins or bills with cheap NFC in them so that the value of the physical thing is almost zero, but it holds certain amount of Bitcoin, verifiable somehow. This solution probably will require some third party that basically escrows the funds, but if that's possible, then you would be able to trade bitcoin offline basically by just passing around those NFC enabled coins/bills. I'm not sure if it would be possible to somehow confirm that the NFC holds certain amount of Bitcoin offline, but at a minimum it should be possible to check with an Internet connected phone, which are common in the developing world. Also it could be a device, like an ATM for example, shared among a group of people that could just go there to verify their coins/bills, without the need for them to have an internet connected device themselves. I think this could be potentially more secure than a simple QR code printed out, since there are specialized NFC chips that protect for certain known attacks. |

Another important thing considering security is the use of signed miner. Excavator (QuickMiner) is in-house built. It is not developed by an unknown developer. Using software from unverified sources could be an issue for some users using the miners on personal PC. We offer them a secure way of mining with QuickMiner.
By the way, where can I find the modifications you guys made to xmrig? It's distributed with your closed sourced GPU miner(excavator) to mine with the CPU: XMRig miner ( https://github.com/xmrig/xmrig); we have compiled version 6.7.0 with some modifications. The miner is stored in Excavator and it is extracted and launched when needed for CPU Mining. Since xmrig is released with a GPL license, any redistribution of it requires sharing the modifications. I didn't find any source code for xmrig at https://github.com/nicehash/excavator so maybe they are published somewhere else? You seem to take these issues very seriously, so I'm sure you're publishing those modifications somewhere to comply with the GPL: WARNING!!! Excavator is a proprietary software by NiceHash and has a special EULA. YOU ARE NOT ALLOWED TO REDISTRIBUTE IT! |

I have to side stompix's opinion here, if you really can't hit the minimum payouts for most pools, you are wasting your time and efforts.
It's not only for older inefficient miners though, you can also run a tiny home silent operation that costs you very little electricity and gives you a couple of bucks a week. For example you can run an absolutely silent Apollo BTC at 2.1TH/s using 120W only. At any pool it would take you months to get anything, but with NiceHash you can get a few sats every week or two via lightning. Also, depending on your electricity costs, you can actually make money with this. It's just a small and silent operation at home, you're not necessarily wasting money in certain configurations:  Also, some people might want to basically buy Bitcoin through the electricity bill as well, and nicehash allows this for tiny miners. |

When I go to the website solo.ckpool.org, and I try to look up my mining history by entering my BTC address to https://solo.ckpool.org/usersI get a page not found error. Is ckpool.org really operational? The pool is working fine, so it's something on your end. Some things to check: Miner Software: Make sure that your miner is actually mining properly. Do you see a hashrate number being displayed in the miner software/dashboard? Hashrate: Are you providing a very small hashrate?, even at 300GH/s (one Compac F) the summary should appear immediately. If you're pointing a very old miner, or a non-asic device, then it will take forever to appear and it will display the error in the meantime. URL: Of course, any mistake in the URL would generate that error. Double check that you're using the same BTC address you used in the miner. |

One thing that is important to point out is that the bitcoin you're storing in a hot wallet like your Bitcoin Core one shouldn't have more than a small amount. This is because it's basically not as secure as the bitcoin you're storing in a cold wallet.
I don't see the point in having multiple cold storage wallets, but it doesn't hurt as long as you keep them secure. If the amount you're storing is very large you might consider having multiple signatures for a single cold storage wallet to increase security though.

This doesn't make any sense.
At that time he was mining Bitcoin with a normal computer, and Bitcoins were basically worthless, so basically he got the pizzas for free.
He actually continued to mine and get more pizzas, even when lightning was new he bought more with it.
Bitcoin is money, you can do whatever you want with it.
People think that he only had 10k BTC and traded it all for pizza. That's nonsense. Most people that say Laszlo made a mistake usually don't know the history of how that happened.
It was actually a great thing to do, not a mistake at all!.
