- bitcoin-qt sync issues and slow speedsJul 13, 2026
It's known Rasperrby Pi 4 (even you own 8GB ones) struggle to sync not only due to somewhat slow CPU, but also due to total UTXO above RAM size. Although if you haven't allocate Bitcoin Core to use most RAM, you can by…
I disagree. The difficulty will simply drop low enough for few miner able to continue mining at profit. Besides, i expect some Bitcoin enthusiast will start/continue mining to keep the network alive. The idea of LN…
Just like previous halving, some miner will stop their mining activity and sell hardware they no longer use while other's will continue mining with lower profit. I think you're overestimating LN as scaling solution.…
Aside from what other member say, it means Signet is better choice for some people. Not if the 51% attacker mine empty block, which prevent everyone TX from getting confirmed.
I don't know what you're trying to build. But in case you mean you actually mean you want to test/try something, consider Signet network instead. Looking at the recent blocks[1], there's almost no empty block mined. I…
AFAIK if your script can be represented with Miniscript, Bitcoin Core can execute or spend it. But i never tried it personally and IMO this kind of question should receive better answer either on…
I don't know any other way beside using createrawtransaction on Bitcoin Core. Although according to https://bitcoin.stackexchange.com/a/120862, you can import your address to Bitcoin Core with help of descriptor…
Where are source, discussion or data which can prove those statement? You said old smartphone have enough storage, but then mention microsd or external harddrive as requirement. It's also worth to mention you could use…
- Thoughts on repurposing old phones and tabletsAug 17, 2025
"can" or "cannot"? OP talk about old device though, so i have doubt those are fast or powerful enough to run node of those altcoin. And AFAIK, some of those altcoin expect you to own or temporarily freeze some amount of…
- Thoughts on repurposing old phones and tabletsAug 15, 2025
Very bad. Have you ever compare Bitcoin mining hashrate between CPU, GPU and ASIC? In short, ASIC usually is thousand times faster or more efficient than CPU. Refurbish and then selling those old devices would be more…
- Node shut down unexpectedly without errorsAug 8, 2025
Bitcoin Knots it's not fork. It's alternative Bitcoin full node software. Aside from out of RAM/memory, there's possibility it suddenly closed itself due to something called "segmentation fault". Usually it's caused by…
Doesn't most app that give Bitcoin when you mine altcoin either take big cut or require KYC (such as Nicehash)? I did quick and rough research, but doesn't seem to be profitable either. WhatToMine shows single Nvidia…
Just half a year ago, similar question was asked on Bitcoin mining using an Android phone. You can see everyone's answer, where most of them sound similar. Financially it doesn't make any sense. But if you just want to…
- Which node should I run right now?Mar 26, 2025
FYI, this full node software load all UTXO with RAM. When i tried it in middle 2022, it use 14.9GB of RAM[1]. Jameson Lopp also tried benchmark it back in December 2025, but always run out of RAM with his 32GB RAM…
- Which node should I run right now?Mar 24, 2025
Yeah. Have you seen https://blog.lopp.net/knot-a-serious-project/, only section "Luke's Security Practices"? Bitcoin Core is still most popular option today. But if you need some automation and process many payment…
Rated Input Voltage 365 ~ 418V Not for the home miner
Usually it means either exchange > your Bitcoin address > mixer or exchange > mixer. Exchange invade our privacy, by tracking our coin after withdrawn. Here's old example for Wasabi (CoinJoin, not custodial mixer),…
Make sure the private key generated within valid range. It should from 1 to FFFFFFFF FFFFFFFF FFFFFFFF FFFFFFFE BAAEDCE6 AF48A03B BFD25E8C D0364140. Not all software/library throw error or silently perform modulo if you…
No. What matter most is the RNG source used by script/wallet software you use. FWIW Debian ISO file also include Electrum. To be specific, debian-12.4.0-amd64-BD-2 include that (based on it's list file[1]). Or you could…
- Are there traces left by wallet.dat files?Aug 17, 2024
Depending on how paranoid you are, there are few things worth to mention. 1. Swap file/partition isn't cleared when you perform shutdown. 2. TRIM only run on certain schedule (e.g. daily or weekly). So until then your…
