I noticed something pretty unusual while looking through Bitcoin block data. The same Bitcoin address received the coinbase rewards from four blocks mined within roughly 20 hours and 9 minutes: 2026-10-23 05:12:20 2026-10-23 10:53:46 2026-10-23 11:43:51 2026-10-24 01:21:17 All four coinbase transactions paid to the same address: bc1qevfvr7n7hqu56eu5cqunk22nuwds0dkjgqqxe6 The rewards were approximately 3.13 BTC each, totaling approximately ~ 12 BTC . I also noticed an earlier block reward paid to the same address on October 22, at 02:10:14, bringing the total to five block rewards associated with this address in roughly 47 hours. The blocks were labeled as mined by an unknown miner. Obviously, that label alone doesn't prove that this was a solo miner, and the address itself doesn't establish who actually mined the blocks. Still, the timing caught my attention. Finding multiple blocks in such a short period seems like an interesting statistical event, especia...

I would like to know whether it is feasible to include a data in the ScriptSig field of the coinbase transaction such that this data is revealed later ( say one hour later which is the average time to create 6 blocks). By revealed I mean everyone can execute the ScriptSig and learn this piece of information one hour after the block has been published ? I was wondering whether using the "op_checklocktimeverify(sequence, tx_locktime)" opcode in the ScriptSig field of the coinbase transaction could positively answer my question ?

I’m helping a friend recover access to a Bitcoin wallet that was originally set up around 2018 using someone else’s first-generation Coldcard (presumably Mk1). My friend is not technically knowledgeable and doesn’t remember the exact setup or backup procedure. What we currently have: A USB flash drive that he believes was used to store or back up the wallet. A handwritten sequence of 12 words. A handwritten 6-digit PIN. A Bitcoin receiving address previously used to check the balance around 2020. We are not certain whether the original Coldcard device is still available. What I’m trying to understand: From the Coldcard documentation I’ve found, encrypted wallet backups can be protected by a separate 12-word password, which is different from the wallet’s BIP39 seed phrase. I’m therefore unsure whether the handwritten 12 words represent: The actual BIP39 recovery phrase for the wallet; or A password used to decrypt a Coldcard backup file. I’m also unsure wha...

I am trying to identify a Bitcoin-related service or wallet that I remember using around 2009. I understand that modern mnemonic recovery seeds (such as BIP39) did not exist in 2009, and I am not claiming that this was a modern seed phrase. My recollection is the following: I was introduced to Bitcoin by a friend. I created a new email account specifically for this. I registered on a website with an email address and password. I bought Bitcoin for a small amount of euros. My recollection is that payment was made by bank transfer from a German bank account. Afterward I could see a Bitcoin balance associated with my account on the website. I was advised to move the bitcoins to a wallet so that I would still have access to them if the website disappeared. I did not install wallet software. I remember doing this in the browser. During this process, the system generated a number of apparently random words for me. I understood these words at the time as a password/passphrase and...

Today I was back at trying to sign a transaction spending a musig UTXO in Bitcoin Core. Last time around, Pieter W. gave me two pieces of advice. Use PSBTs, as they're more likely to work on modern stuff like Musig than raw transactions. He asked how I was generating my private/public keys, which made me realize I'd probably calculated my pubkey incorrectly. So today I took a new swing, using the same methodology I use for signing regular multisigs in Bitcoin Core, but now I can't get the PSBT to process correctly. I. Capturing the Individual Keys I used the simplest method possible to generate a musig address: grab addresses from two different wallets and capture their pubkeys. (The private keys should then be sitting in those wallets.) Here's the address & pubkey capture: musigaddress1=$(bitcoin-cli -rpcwallet=musig1 getnewaddress) musigaddress2=$(bitcoin-cli -rpcwallet=musig2 getnewaddress) musigpubkey1=$(bitcoin-cli -rpcwallet=musig1 -name...

I recently installed Bitcoin Core 32.0rc2 on one of my nodes and noticed that the reported P2P protocol version changed from 70016 to 70017. I remember 70016 being used for quite a long time, so I was curious what exactly triggered the protocol version bump. What changed in protocol version 70017 compared to 70016? Also, how does a 70017 node behave when connected to a peer that only supports 70016? from Recent Questions - Bitcoin Stack Exchange https://ift.tt/Pz5vkwX via IFTTT

While learning Bitcoin transactions and SegWit, I came across the distinction between the traditional transaction ID (txid) and the witness transaction ID (wtxid). I understand that the txid is the double-SHA256 hash of the serialized transaction excluding the witness data. andd wtxid commits to the transaction including the witness data. SegWit introdduced wtxid partly to solve transaction malleability issues. What I am having trouble understanding is why Bitcoin needs both identifiers instead of simply replacing txid with a hash that always commits to the witness data. For example, suppose a SegWit transaction has the same inputs and outputs but different witness data. The txid remains unchanged while the wtxid changes. I would like to understand the design consequences of this distinction... What specifically would break if Bitcoin used only wtxid everywhere? Why do transaction inputs continue to refer to previous outputs using txid:vout rather than wtxid:vout? How doe...

I'm currently doing the Initial Block Download (IBD) of a Bitcoin Core node. For most of the synchronization, everything behaved as expected. The node was using the resources I made available to it: CPU usage was high during validation, RAM usage increased according to the configured cache, network bandwidth was being used, and the synchronization rate varied roughly between 2% and 5% per hour , with a peak around 5%/h. I then left the node running for about a week while I was away. When I came back, it was around 68–69% synchronized , but the effective synchronization rate had fallen to approximately 0.03% per hour . This had apparently happened several days before I returned. Before leaving, the node was around 20%, so even a sustained 1%/h rate should have put it much further ahead after several days. There was also an unexpected power outage while I was away, which caused the node to shut down abruptly. However, I don't see any indication that the outage ...

Imagine a multisig wallet with cosigners comprising say 2 (software) Bitcoin Core wallets, and 3 hardware signing devices, in a m-of-5 multisig setup. Do experienced bitcoiners foresee a problem with this setup? Specifically, the wsh(sortedmulti(..)) descriptor will mix address paths - Core's m/84'/0'/0'/0/* xpub with hardware wallets' m/48'/0'/0'/2' BIP-48 derivation paths. I understand that coordination software won't care about different paths to derive receive address, but could there be other issues, long-term? I do understand we can simplify things with just m/84 or m/48 paths within the multisig, but question is about mixing paths.

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.

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...

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...
