Would fpga mining steal beat gpu mining today?

Of course, only ASIC is relevant today. But before bitcoin asics became available, fpga based bitcoin mining out competed gpus. Back at that time, gpus were mainly floating point oriented. But would a modern Stratix 10 Gx with over 12 million lut still beat a RTX4090 in terms of mining profitability? from Recent Questions - Bitcoin Stack Exchange https://ift.tt/U3Wg2SD via IFTTT

Bedroom mining overnight... is dB rating even the right thing to compare?

So i've been going back and forth on whether to put a mining heater in the bedroom for winter. My apartment runs cold and i already spend money on a space heater, so the math kinda makes sense on paper. But every comparison i see focuses on the lowest dB number on the spec sheet. And honestly i'm not sure that tells you much about whether you can actually sleep next to the thing. A steady fan at 38dB can totally disappear into the background — my air purifier is around that and i forget it's on. But a fan that ramps up and down, even if it's technically "quieter" at its lowest setting, would absolutely wake me up. The change in sound is what gets you, not the volume itself. Which got me thinking... would you actually run a Bitcoin heater in a bedroom overnight? Like has anyone here done it and not just for a single night but consistently? I've been looking at the Avalon lineup since they seem designed for this use case. The Mini 3 is more inte...

Schildbach Bitcoin Wallet 2014-2016

Currently seeking advice on where and how to access my Shildbach bitcoin wallet from 2016. I have access to my encrypted private keys and I know my password.

Hello, everyone.Can a Bitcoin node build a partial UTXO set from only the most recent blocks and use it to validate new transactions?

I am investigating whether a storage-constrained Bitcoin node could retain only the most recent (N) blocks, construct a partial UTXO set from those blocks, and use that partial UTXO set to independently validate newly received transactions. The basic idea would be: recent (N) blocks → construct a partial UTXO set → validate a new transaction locally if all of its input UTXOs are available in that partial set. However, I see a potential bootstrap problem. Suppose the node starts with only the most recent (N) blocks. Some transactions in the earliest retained blocks may spend outputs created before the retained window. Without the earlier UTXO state, the node cannot fully validate those inputs. If the node therefore cannot fully validate those blocks, can it safely treat the outputs created by those blocks as valid UTXOs and progressively construct a partial UTXO set from them? More generally: Is it technically feasible for a Bitcoin node to construct a trustworthy pa...

If a BIP39 hardware wallet is lost, what exactly is recovered from the seed phrase?

I’m trying to better understand the relationship between a hardware wallet, a BIP39 seed phrase, and the actual Bitcoin keys. Suppose a user initializes a hardware wallet, receives a 12- or 24-word recovery phrase, and later completely loses or destroys the physical device. If the recovery phrase is imported into another compatible wallet: What exactly is being reconstructed from those words? Are the same Bitcoin private keys and addresses deterministically regenerated? What additional information might still be required, such as a passphrase, derivation path, or wallet type? Are there situations where having the correct seed phrase alone would still not be enough to recover the expected Bitcoin wallet? I’m specifically interested in the Bitcoin/BIP32/BIP39/BIP44 side of this rather than device-specific recovery instructions. from Recent Questions - Bitcoin Stack Exchange https://ift.tt/sL8QHjT via IFTTT
