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. Just curious because this site was also listed in my backup email I had saved. Not exactly sure how to go about my next step. from Recent Questions - Bitcoin Stack Exchange https://ift.tt/qB8pAoT via IFTTT

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

What Is a Blockchain, and How Does It Work in Bitcoin?

What Is a Blockchain, and How Does It Work in Bitcoin? A blockchain is a type of distributed database that stores information in a sequence of blocks. In the context of Bitcoin, the blockchain is a public record of confirmed transactions that is maintained and independently verified by network participants. Each block contains a group of valid Bitcoin transactions, along with other data required to connect that block to the existing chain. The term blockchain comes from this structure: information is stored in individual blocks, and each new block is cryptographically linked to the previous one. How are blocks connected? Every Bitcoin block contains a reference to the previous block through its block header. This reference is based on a cryptographic hash. A hash is a fixed-length output generated from data. If the underlying data changes, the resulting hash also changes. Because each block refers to the previous block, changing historical data would break the links...
