Is there a point to using taproot transactions over P2WSH if I only want to use the script path?

Interested in making an HTLC, in which case there should not be a key spending path. According to this post , one can set the internal public key to an essentially arbitrary value and just use the script path. But then is there any advantage to using P2TR over P2WSH? from Recent Questions - Bitcoin Stack Exchange https://ift.tt/BT6hStN via IFTTT

AVG antivirus quarantines Bitcoin-Qt

I verified the Bitcoin Core V28 (MacOS) download using the usual recommended methods, but my antivirus software detects "malware" with the attached message. Is this normal, and should I be concerned? Is there a way to bypass this as otherwise I can't run Bitcoin Core on my machine?

Taproot Sighash ans Schnorr

I have done all possible checks: signhash and taproot calculation, no changes in BASE64 processes, empty symbols, Shnorr validity and that BASE64 is exactly 64 (not 64 + 1), but I get the same error every time. Logic: 1. Receive psbt and decode -> Sign inputs (I don't finalise, the server does) using Default method (ALL the same result)-> encode in Base64 -> return partially signed PSBT to server. I get the "Invalid Schnorr" error every time by server. You see, if you compare script PSBT and output psbt, they are 99% identical except for Shnorr (field unknown 13). I've attached a screenshot to show the difference. I thought the problem might be in the formats for the server, but also Bitcoin cli analyse returns an ‘updater’ status for my script output: { { ‘result’: { { ‘inputs’: [ { ‘has_utxo": true, ‘is_final": false, { ‘next’: { ‘updater’. }, { ...

How to export data from Binance spot chart?

I need to export data from Binance spot chart: https://www.binance.com/en/trade/BTC_USDT?type=spot . I need data like this: High price Low price Open price Close price I also need MACD indicators: 9-day 12-day 26-day Numbers are needed for each week or any other time frame I set. I will also need to export other data like RSI, MFI in the future. And also for other cryptocurrency pairs, not only BTC-USDT. So the solution needs to be scalable. I do one research, so need this data.

Do miners calculate the balance including the mempool?

Let's say you got 1 BTC. And you do the following: Send a transaction of 1 BTC to address A; fee: 1 sat/byte If you'd only calculate what's in the blockchain, you'd still have a balance of 1 BTC. But if you also include the mempool you'd have a balance of 0. Am I now able to send a second transaction, such as: 1 BTC to address B, fee: 1000 sat/byte The second transaction would likely be confirmed first; what would then happen to the first one? Would it simply be lost since now I don't have enough balance anymore? from Recent Questions - Bitcoin Stack Exchange https://ift.tt/8cLxQmF via IFTTT

When Satoshi Nakamoto mined his first set of blocks in 2008/2009, it was on Bitcoin Core, but was he using Linux or Windows?

The question seems anecdotal but it has an importance when reading the old key.MakeNewKey() source code : At that time, block rewards of 50 BTC were sent to a newly generated pubkey at each blocks. As far I can tell, each key were added to the wallet at the approximately the block’s timestamp. Bitcoin Core was using /dev/urandom on Linux but on Windows even when openssl was asked for secure randomness, the generator had to be initialized manually each time to a initial value : and in the case of key generation, that value was set to HKEY_PERFORMANCE_DATA by Satoshi  ! So if I’m not wrong, this means block rewards mined by using Windows had weak randomness as the possible values are far more limited than the secp256k1’s order. As a result, does this means he only used Linux personally? from Recent Questions - Bitcoin Stack Exchange https://ift.tt/rnNlyKD via IFTTT

Subscribe PSBT inputs via Golang

I wrote the code to partially sign the PSBT. Briefly the server sends me a PSBT in Base64 format and N inputs to be signed. I encode the PSBT, sign the inputs with PK using Schnor method. I update it back to Base64 and send it to the server (not finalised PSBT with unsigned input 0). This is how it should look like after processing (correct): { { ‘result’: { { ‘inputs’: [ { ‘has_utxo": true, ‘is_final": false, { ‘next’: { ‘updater’. }, { ‘has_utxo": true, ‘is_final": false, { ‘next’: ‘finalizer’. }, { ‘has_utxo": true, ‘is_final": false, { ‘next’: ‘finalizer’. } ], ‘fee": 1.328e-5, ‘next": { ‘updater’ }, ‘error": null, ‘id": null } This is what it looks like after being processed by my script. The Updater status should change to finaliser for those inputs I signed, but it doesn't (incorrect) : { "result": { "inputs": [ { "has_utxo": true, "is_final": false, "next": "updater...

Stuck Bitcoin Core Wallet can't send out

I have a wallet from 2013 that has a fair amount in it I'd like to get to. I have it restored on bitcoin core on a few separate machines, each with a full node. When I made it I didn't put on a passphrase but it now asks for when when I try to make a transaction. On one machine only it will not ask for a passphrase if I go through Bitcoin CLI. I also can't get it to give the private key so that I can import it to electrum. It will either ask for a passphrase or it will say that there isn't a private key known. When I do a dumpwallet I can't seem to find the right private key to import to electrum. I might just not know which so any help with that would be appreciated. When looking at the transaction to rebroadcast them it says that they have bad-txns-nonstandard-inputs (code -26). This may be due to some dust, the lowest amount I have on a singular input is 868 sats. I've tried to sendmany to conjoin it but when I do it tells me that there is a JSON parsing er...

How does Bitcoin Core Wallet calculate the weight of each input before it's spent?

The Bitcoin core wallet selection algorithms, particularly coin-grinder use a weight metric for each output. My understanding is that an output's weight is composed of the base_weight which is a constant amount plus a satisfaction_weight which is variable depending on the type of output and script/arguments needed to unlock it. My question is, how does bitcoin core know the weight during coin-selection before it's actually spent? Is this weight an estimate based on the type or is it accurately computed? from Recent Questions - Bitcoin Stack Exchange https://ift.tt/bvytoSx via IFTTT

HBO's "Money Electric" Documentary - What’s the Truth?

"The Money Electric: The Bitcoin Mystery" by HBO finally aired on the 8th of October, with the documentary outing Peter Todd as Satoshi. Sure, the producer, Cullen Hoback, did his best to prove his point. But there’s a whole lot more to consider before making a final call. Who is Satoshi Nakamoto in the Crypto Industry? First, let’s understand who Satoshi Nakamoto is and why unmasking the person behind the name is so fascinating. Satoshi Nakamoto is an elusive figure who figured out that the traditional cash system was dying and came up with an idea to make a new type of money. The fruit of their idea is Bitcoin, the very first successful cryptocurrency. We use the word “successful” because there were other attempts before Bitcoin that failed. Satoshi Nakamoto published the Bitcoin whitepaper in 2008 and mined the first block the following year. After getting spooked by how the project was progressing, Satoshi slowly withdrew themselves from the topic before finally disap...

Watch only Bitcoin address in Sparrow

The task seems easy, yet it’s very hard to complete. I want to watch a Bitcoin address in Sparrow. It’s a multisig address starting with 3*. Here’s what I’ve tried so far: New Wallet Policy Type: Single Signature Script Type: Nested Segwit or Legacy (neither works) Master Fingerprint: 00000000 Derivation: m/49’/0’/0’ xpub: Bitcoin address starting with 3..

Hey guys I'm newbie here few bitcoincore or sparrow questions

New to bitcoin, Im a little confused with this new area and try to set the bitcoin as saving to protect my assets being devalue. I learned from the bitcoin website that using Bitcoin Core to generate public and private key, the process is download official fies from web and copy to a new USB drive and put it in a new computer that completely offline, then run Core file in a offline operate system, (and avoid download the whole chain) and generate wallet key offline, after that, make a copy of wallet.dat, backup in 2 or 3 new usb drive and write my private key down. If come to saving coins,heres my question: 1.After finish creating the wallet, do i have to physics destroy my new computer? If i keep my new computer offline all time would i be able to keep my computer? 2.Due to the bitcoin core, If i only remember the private key but lost my .dat file, what happened to my wallet then? 3.Is Sparrow wallet better or friendly?

How Can We Develop a Methodology to Measure Bitcoin’s Actual Value Creation?

I seeks a clear and actionable methodology to measure Bitcoin’s unique value creation compared to other cryptocurrencies, stablecoins, and traditional financial systems. Specifically, they are asking: How can we reliably differentiate Bitcoin-specific value creation (e.g., from decentralization, censorship resistance) from general blockchain-based financial innovations? What measurable metrics or frameworks can demonstrate how Bitcoin’s decentralization translates into actual economic value, rather than simply describing potential benefits? How can Bitcoin’s value creation be compared to technology companies like Google, Tesla, or Amazon, whose market cap reflects their contribution to increasing the economy’s productive potential? Existing ideas in the conversation include analyzing remittance cost savings, transaction efficiency (e.g., Lightning Network), and financial inclusion through wallet adoption. However, these metrics often describe potential benefits rather than ...

Legit profits or likely scam?

new to bitcoin world and I got hooked up with a trader calling himself David O. Nelson and the website was MajorfxHawk. I have doubts to it’s authenticity especially when I incurred an upgrade fee when my $1,000 investment in 5 days earned $40,000 in profits. Repeatedly promised I would have access to profits as soon as I paid upgrade of $4,000. It wasn’t tue and that $5,000 investment had now earned $80,000. They just sent my profits to Coinbase wallet and I have a Withdrawal Mempool tax of nearly $4,000 which needs to be paid before I have access. I believe this is just another step in the scam. Paying this fee does not guarantee my money does it? My brain says if I pay, the profit will magically disappear. I would like to hear from more experienced traders.

Bitcoin arithmetic, symbol definitions, from private key to public address

(Note, please see EDIT below.) I title this with “arithmetic” because “mathematics” is an abstraction for arithmetic and a mathematical function can be broken down into arithmetic. I need the arithmetic. The top level question / goal: I am trying to understand the arithmetic in how a private key is translated into a public key. Presume my wallet has generated a private key for me. What are the steps the wallet (and/or the bitcoin nodes) use to create the public key that it uses to deposit coins into? I have found and read multiple articles, but am not recognizing the steps. But before going there, I need to solidify the meanings of a few symbols. Start with this post found from a search: What is the math behind Bitcoin's elliptic curve? Q, k I don’t know what these represent. G from another post I find this: “The generator point G, or a ECDSA public key, is a pair of coordinates x and y, for which the above equation holds.” I presume this mean some specific point on the curve, ...

How light can an input be?

In the bitcoin-core reference client, CFeeRate::GetFee is a function of num_bytes . What is the smallest amount of num_bytes that a TxIn can be in practice as it pertains to calculating that inputs effective value? The reason I ask is that there are some test cases in the core wallet that use 150 bytes which seems unrealistic. The transaction calculator shows taproot as the most compact at 57.5 vB or 230 bytes I believe. The reason why 150 bytes is problematic is that it's difficult to faithfully reproduce that calculation using the rust-bitcoin framework for example, since the effective_value calculation implies at least inputs of 160 bytes due to the output and sequence size implicit in all effective_value calculations. Of course, a test could be made for 160 bytes instead which would probably have identical results, although I'm mostly curious why 150 bytes was selected here and if there's some practical oversight in the rust-bitcoin effective-value calculation. ...

Does the user not need to specify the amount in the transaction creation process as the amount is implicitly determined by the UTXOs they select?

I'm trying to understand the Bitcoin transaction creation process and how inputs and outputs work. From what I know, when a user creates a Bitcoin transaction, they typically select UTXOs (Unspent Transaction Outputs) as inputs to the transaction. Given this, it seems that the amount of the transaction is implicitly determined by the UTXOs selected, since the sum of the inputs is what gets spent. In other words, the total amount of Bitcoin being sent would be based on the value of the UTXOs used in the inputs, while the user doesn't need to explicitly specify the amount. Is that correct? Does the user really need to specify the amount at all, or is it entirely determined by the selected UTXOs? And if there's any difference, what is the role of specifying the amount in some wallet interfaces? from Recent Questions - Bitcoin Stack Exchange https://ift.tt/zImtyc2 via IFTTT

How do HD wallets store the keys and addresses?

As far as I'm aware, the recovery code is presented to the user once and then not stored at all by the wallet, in which case, it has to store at least the master private key, and would also probably store all the addresses (as it would be inefficient to regenerate them each time they are needed) How exactly is all this stored? From here , I see that all addresses are identified using a path naming convention. Does that mean that all the paths are stored, and in a scenario where an address needs to be reused, it is regenerated each time? from Recent Questions - Bitcoin Stack Exchange https://ift.tt/04tdVoz via IFTTT

Are there 2^160 possible addresses or 4*2^160 (4 address types) possible addresses?

Let's say Bob tells you to send him btc and he gives you a p2pkh address whose underlying 160-bit number is, say, 12345. You can't just convert that to the taproot representation of 12345 and send btc to that taproot address; Bob wouldn't receive that right? So, effectively, for any given 160-bit number, there are 4 different addresses you can generate from it, and sending btc to one address type would indeed send only to that address type, and the other 3 would not receive it? from Recent Questions - Bitcoin Stack Exchange https://ift.tt/2x3TmPj via IFTTT

In Utreexo, how is it guaranteed that the validator has the same accumulator state as the proof-generator?

In Utreexo a validator node (fully validating Utreexo light node), when validating transactions, uses the proofs supplied by the proof-generator (a Utreexo-aware full node, bridge node). As far as I understand, for proof validation to succeed, the validator has to have the same accumulator state (same root hashes) as the state used when creating the proof. I wonder how can this be ensured in the different use cases. For the newly confirmed blocks/transactions, I see no problem, as the confirmed blocks and transactions have a well-defined ordering, and it is safe to assume to base the proof on the accumulator state as after the previous block. But what about a long-confirmed but still unspent UTXO? Relative to what state can it be proved/verified? Does a new current proof have to be created with the current block height? Or it's not possible in Utreexo? Also, what about mempool transactions? Their arrival time can differ in nodes, so there is no clear block height or block state....
