Please deposit and withdraw BTC (testnet) and ETH (testnet Rinkeby) if you can, trade around and help iron out bugs (if any).
1. Honestly you'll have harder time looking for tester since not everyone have testnet coin. As for myself, i returned few micro tBTC to faucet where i got tBTC after i done experimenting with LN few years ago. 2. Since it's not easy to obtain tBTC in big quantity, you should specify minimum withdraw/deposit amount of your exchange. |

Is there any danger in uploading the debug log to this forum as I did? Could the information in the debug log help malicious users gain access to my computer or my network?
Short answer: No. Longer answer, Aside from what @nc50lc said, debug.log contain basic system information and Bitcoin Core configuration. Merely knowing what OS do you use and value of your configuration isn't enough to comprise your system. |

Seems the permission denied errorwarning is expected and does not indicate the issues. One more thing I would try to check is: cat /var/log/syslog | grep tor Don't forget grep is case sensitive, so it should be Tor (not tor). # -b -0 indicate current boot
sudo journalctl -x -b -0 | grep Tor
sudo cat /var/log/syslog | grep Tor

I have an open source program suggestion that may be of use to you - Portfolio Performance[1].
For those who wondering where's the source code, it's available on https://github.com/buchen/portfolio (i managed to find out since they use GitHub to host the installer/binary). Too bad their forum/help page only available on German language. |

This isn't bad idea, but it's definitely not suitable for Bitcoin where decentralization and backward compatibility are greatly valued. Your idea could be more well received on altcoin community/developer which use PoW and don't really care about decentralization. Benefits to this is you are doing 'useful' work but the downside is no one probably cares about folding that random protein.
But some people definitely care about the benefit, although only very few regular people who know about benefit. |

The downside is the faster NUC is more power hungry.
I have one of those power meters, and when I tested NUC consumed around 13W on regular use (not with Bitcoin core), idle is bit less and when shutdown it was 2W for this model. This is decent and less than my older Netbook with power plug, but probably more than Raspberry Pi would consume. Correct, even Raspberry Pi 4 (without any USB device) consume about 7 watt during high load. Official Raspberry Pi blog made good article about it at https://www.raspberrypi.com/news/thermal-testing-raspberry-pi-4/. One thing that I like about Rpi is that it can be totaly silent (especially Pi 400), and for NUC I can still hear that little fan buzzz, but nothing terrible.
But for 24/7 usage i would use active fan, especially if i use case or place it on room with high temperature (above 25C/standard room temperature). |

But coming back to my original question, technically speaking, what sort of crypto framework could suit best this use case?
Within decentralized/P2P system, there is none due to oracle problem. |

Used IP addresses are logged and recorded so it's better to use Tor browser when sending SMS with this website (if possible).
I managed to open the website with Tor Browser and tried the API with Tor (there's option to use SOCKS5 proxy on cURL) without any problem, so i guess it's possible to use Tor/Tor Browser. |

I understand that you are just testing this, but I still don't think it can be called an airgapped cold storage solution. There must be a distinction between a setup that doesn't have the required hardware to establish a network connection and a device that has but only has it turned off by enabling flight mode. Your airgapped system becomes a hot wallet by sliding your finger down the screen, disabling flight mode, or enabling WIFI. It's not enough for an attack, but the prerequisites for one are there. Nevertheless, it's an interesting concept to think about.
Tails OS or similar USB sticks is seen as a good option for simple and effective cold storage. Still, if one forgets the network cable plugged in to the laptop, he may have surprises. Or if you have a properly airgapped Windows laptop with cold storage and somebody else from your family plugs the network cable in,... same story. I mean that there are always this kind of risks. In most cases for home brew cold storage the prerequisites are there. It's definitely big concern if you use Windows as airgapped storage. But with Tails, there are less concerns since, 1. You usually need to manually choose boot to Tails. 2. Tails doesn't connect to Tor network automatically. 3. Tails is designed with security and privacy in mind, so it's unlikely your Tails compromised when you connect it to network/LAN cable. |

But it is definitely possible to implement NFT directly on Bitcoin; simply through using a coloured coin. To be honest, we have these for years and they can directly act as an NFT without any modification to the spec. Colored coins prove majority of Bitcoin community don't really care about NFT/token which shown by lack of interest. What we need to keep in mind in topic of NFTs (or by extension tokens) is that there has never been any connection between the token and the underlying object whatsoever. For example in case of artwork (digital or physical) it is an arbitrary data (eg. a hash) that is stored in a blockchain and a non-existent link between that data and the art.
For some people, it's not connection between NFT/token with object. NFT is proof that you're legitimate owner of the object, although it has no legal power and many people don't care about it. |

Every year the network should revisit the requirement and make sure that it takes roughly a given timeframe on a decent desktop per kilobyte, say 8 hours for 1kb (so you could run it while you sleep).
Decent computer shouldn't be standard since most people use smartphone (which have less computational power) or old hardware (e.g. 10 years old laptop or RPi 3). Question: won't this mean that no one will use coins to pay transaction fees? ↑
No, this process is designed to take time and so just paying the very small transaction fee will probably almost universally be done, especially for financial transactions which people need done quickly.
If the protocol discourage people from batching transaction, this will lead to bloated blockchain. Wallet and services will make lots of smaller transaction to reduce computational usage. |

With his experience, it's likely he'll back into Bitcoin development (whether for Bitcoin Core or other project). Some cryptocurrency company give back to Bitcoin community by hiring developer solely for Bitcoin development, so i expect some company will give him such offer after he finished his PhD. This may or may not be the reason, but it shows the flaw of having developers that are doxxed; and that we definitely need more developers that are anonymous.
Additionally, there should be viable alternative for centralized platform such as GitHub. Few repository such as youtube-dl become victim of abuse of the DMCA. |

Are there any projects like this?
Check https://memo.cash/ which utilize BCH network. It's more practical than your idea since there are already incentive to run the node/mine the coin. |

From what i've seen, most guide about setting Onion Service on Bitcoin Core usually enable bind=127.0.0.1. Enable it first and restart your Bitcoin Core process.

and this is currently available only for BTC/BSQ swaps.
If it's the only available pair, then only existing Bisq user which could feel the advantage. New user don't really care about consensus on Bisq DAO even though BSQ also can be used to pay trading fee. I think it's only a matter of time when other stablecoins and privacy coins will be added for swap option in Bisq and I heard some developers are already working on that.
Privacy coin such as Monero already support atomic swap, so i agree it's just matter of time. Not sure about stablecoin whose developer don't really care about decentralization though. |

According to https://restoreprivacy.com/password-manager/reviews/lastpass/, there are some serious privacy concern and past data breach. LastPass collect some user data and based in US. If you really need online password manager, consider BitWarden instead which is open-source and have better security history. Otherwise, i would recommend KeePassXC instead. |

2 tutorial tersebut termasuk dalam kategori full drive/disk encryption. Tapi karena proses yang cukup susah dan panjang, saya sarankan lakukan enkripsi pada proses instalasi saja. |

3. Third-party tracking (such as Facebook and Google Analytic) will know you're interested on cryptocurrency.
I guess that's why many crypto-related posts are now appearing from my dummy account in Facebook long time ago before I stopped trying them, lol. Not that it is really an issue for me due to it being a dummy account, but quite concerning considering that you mentioned in #1, from just sending only an email address. If you find it quite concerning, you should know most website do these simply by visiting their website. I would recommend you to install uBlock Origin ( https://github.com/gorhill/uBlock/) which could reduce the data collection. |

I don't see any benefit compared with other crypto debit/credit card, so i doubt this product will be popular. New user is more likely to use card from more popular company (e.g. Binance) while veteran user would use card which already ready to use.
Well, in case of Ledger card your crypto will be on your hardware wallet and not on the exchange. For me that's a pretty big advantage, given that their fees and ease of use remains somewhat similar to Binance card. Honestly i doubt about part where the coin stay on hardware wallet since the website also say " Top-up & manage your card easily and securely through Ledger Live". Hopefully they don't mean you must send coin to card first so the card automatically convert the coin to fiat at time of purchase. |
