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? Cuz bitcoin core need to copy the new .dat file if you want

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

Bitcoin learning games?

I'm seeking ideas for very simple games involving sending/receiving Testnet Bitcoin? I'm gathering some noobs to show them how to send/receive bitcoin.

Is a spent UTXO immediately deleted from the UTXO set?

Suppose A spends a UTXO of 5 BTC. The transaction is sent to the mempool. Will the 5 BTC UTXO be instantly deleted from the UTXO set? If no, can this UTXO still in the UTXO set be used to make another transaction? Can this UTXO be used while it is in the mempool (unconfirmed transaction)? from Recent Questions - Bitcoin Stack Exchange https://ift.tt/uCSwGO2 via IFTTT

Unable to parse blocks from blk*.dat for testnet (3 and 4)

For the Bitcoin mainnet, I can easily fetch one block by following steps: Open the LevelDB database at <bitcoind-dir>/data/blocks/index Get by key: 629986b32020caeb48a421956936dd88dc8d7825441bbc96fec10e98b800000000 (hex) Just as an example. This is block #12345 with block hash 00000000b8980ec1fe96bc1b4425788ddc88dd36699521a448ebca2020b38699 . Transform it into the internal representation in bitcoin-core and prepend ASCII 'b' to it.

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.
