I am using offline wallet, but I decided to run bitcoin-core for learning. I created a wallet, sent $0.5 to this wallet, first it was showing this amount on my balance, but then after a day or so it shows zero balance. I checked transactions list, it shows that I only had one transaction of receiving $0.5...

I am planning to withdraw some sats from my exchange (Gemini) to my Trezor one . But they seem to have a very strict withdrawal SOP that requires me to prove the ownership of a public address. The problems, as I see, are twofold my trezor wallet has a few sats, but the specific address I created is brand new and I never received any fund there I can send a few sats from my trezor device to the exchange, as a small deposit test, but I do not see a way to control the origin address . I mean, is not my trezor device just the collection of all addresses? I can receive in any of them, but can I send from a specific one of them? So what's the way out here? Does Trezor 1 support this feature? Or have to resort to something else? from Recent Questions - Bitcoin Stack Exchange https://ift.tt/DMOu5Tl via IFTTT

A Scenario Question: If Alice sends UTXOs to an ASP to issue vTXOs for Bob, the vTXO needs to be instantaneous, but the ASP’s on-chain transaction may take a long time to confirm. What happens if the on-chain transaction fails (with funds returning to the ASP)? In this case, could the ASP act maliciously by issuing the vTXO to Bob without backing it up, leaving Bob with unredeemable vTXOs when he tries to cash them out later? Possible Solution: Could the ARK protocol ensure that the ASP only uses Alice's UTXOs after the on-chain transaction for Bob is successfully broadcast and confirmed? Additionally, can Bob's vTXOs indicate whether they are backed by UTXOs or not, notify him of any failure, and maintain a "Not Backed" status until the ASP backs it up with a new UTXO transaction? This would ensure that the ASP can only use Alice's funds after successfully creating a UTXO for Bob, with the entire process being publicly verifiable while respecting user privacy. ...

I bought Bitcoins in 2009 or 2010 from a finance broker who posted his adv online with his name and contact info. he said that he could help people invest in Bitcoin with just just $2 to start, I contacted him and he sent me a link or site (I can't remember it anymore) to register an account, after I had done the account register and sent him money ( just $2) in 2009 or 2010 ?, however, I completely forgot about it over years until today.

It is commonly said that Bitcoin has 128 bits of security because there is an algorithm that can find the private key of a given public key in an average of 2^128 steps. However, this assumes that the attacker knows the public key associated with the funds, so this attack is only possible with P2PK outputs or with addresses that have already been spent from. In the case of an unspent P2PKH or P2WPKH, the attacker only knows the 160-bit address. Therefore, they must first brute force to find the public key associated with the given address. For each attempt, they have a 1 in 2^160 chance of succeeding, meaning the security here is effectively 160 bits. Once the attacker finds the public key, they can then apply the algorithm to find the private key. So doesn't this imply 160 bits of security? Even if the attacker immediately found the private key corresponding to a public key, they would still need to perform a 160-bit brute-force attack first. from Recent Questions - Bitcoin ...

Going through the following resource: When a miner creates a block proposal, the miner is entitled to specify where all the fees paid by the transactions in that block proposal should be sent. If the proposal results in a valid block that becomes a part of the best block chain, the fee income will be sent to the specified recipient. If a valid block does not collect all available fees, the amount not collected is permanently destroyed; this has happened on more than 1,000 occasions from 2011 to 2017,[1][2] with decreasing frequency over time. I understand that transaction fees are eventually refunded to the sender. However, what about the miner's fee?

My friend is using BlueWallet. They created a 1-input-1-output transaction that sends all their funds, but used a feerate of 1.7 s/vB. The transaction has been subsequently stuck for a couple weeks, because no blocks have been including any transactions with feerates of less than 2 s/vB. I’m trying to advise them, but not intimately familiar with BlueWallet. We considered using the RBF feature, but it doesn’t show up for this transaction. (Maybe because no other funds are left?) I read that there is a "Cancel Transaction" feature, which I think will create a RBF transaction that sends the funds back to their own wallet. I guess that it should work, but they’ll have to pay two higher transaction fees in that case. I also considered sending a small payment to the wallet to provide funds for RBFing the original transaction, but then I’ll pay additional fees and they probably would not end up with an empty wallet. We do not control the receiving end, so we cannot CPFP the trans...

I'm trying to work through an attack scenario (say 20 years in the future when block rewards and fees may be more comparable). A miner with say 10% of the hashrate would like invite others to help him selfish mine. Opening up to a pool presents a problem: If the pool is open to anyone, it becomes nearly impossible to mine blocks in secret, so you wouldn't be able to "build a lead" in secret. However, my understanding is that you could design a pool protocol so that you are sending many templates to many miners, in a way that only the miner who found the block knows which transactions are contained in it (This miner is quieted with a small bribe.) Then the subsequent template which you send out contains only the hash of the block. The other miners in the pool can see a new block is found, they are free to broadcast the hash of the block to honest miners. Now non-selfish miners are have a set of options: Mine empty blocks including the hash of the secret block, T...

If I broadcast a transaction of mine, and decide to not put any transaction fee, is there still an incentive for a miner to include it in to the block? Maybe related to this, when the block itself awarded a large new amount of bitcoins when created, the so-called coinbase , would users even include a transaction fee for their transactions? And if not, then what incentivises the miners to include any transactions? Could they not just produce an empty block and get the coinbase anyway? from Recent Questions - Bitcoin Stack Exchange https://ift.tt/1TmrohF via IFTTT

So I know BTCRecover has been around but I have some questions about it before I risk using it... I asked about finding my lost BTC in that I dont know what wallet it was stored in but I have my both seed and also passcode to about a 95+% accuracy but no one suggested BTCRecover? Is there a reason? All threads and posts not only here but others for "BTCRecover" seems to be years ago... is there a reason there is not much talk about it in the last couple of months? If it is legit to use, is this the correct homepage? https://btcrecover.readthedocs.io/en/latest/ And is this the correct Github? https://github.com/3rdIteration/btcrecover Because I also found this but i hear this is outdated? https://github.com/gurnec/btcrecover Is this guy the creator of it? https://www.youtube.com/@CryptoGuide/ If not, is there a great tutorial (preferably video) I can find on using BTCRecover from a legit tech?

I am wondering if there is a way to tell what network was used to send a transaction based on if you have a transaction hash. My inquiry is based off a problem I encountered where an unknown network was used, found on the ETH I.O. Blockscan, I have the transaction hash, but that doesn’t tell me how the sender originated the transaction. Subsequently the transaction was picked up by Coinbases “transfer” account and instead of being redirected to the sent Coinbase account, Coinbase’s transfer account kept the crypto in question, I am currently working with Coinbase to try and “claim” the crypto, but I was wondering how to tell any additional information about what network might have been used based off just the transaction hash itself… also if anyone knows more about the Coinbase issue but I know that’s not what this forum is for so… thank y’all! from Recent Questions - Bitcoin Stack Exchange https://ift.tt/cdnVHJY via IFTTT

I run a core lighning node with a couple of private, single-founded channels. Because of my circumstances my node is usually online for a couple of hours every three days or so. I want to mutually close one of my lightning channels, and am thinking of running: lightning-cli -k "id=${scid}" unilateraltimeout=10800 feerange=[2000, normal] where scid is the short_channel_id of the channel to be closed. I set unilateraltimeout to 10800 seconds, i.e. 3 hours. I consider also setting the parameter to 0 or skipping it (it then defaults to 48 hours) Is it safe to set unilateraltimeout to 0 and go offline when mutually closing the channel? from Recent Questions - Bitcoin Stack Exchange https://ift.tt/lmbQOdf via IFTTT

i want to understand if it is possible to include an absolute locktime during the wallet generation process. If i understand correctly, this would mean that the send function would be non-operational until the block height is reached, and any funds could not be transferred even if the private key was hacked. i am not looking for a way to timelock individual transactions. from Recent Questions - Bitcoin Stack Exchange https://ift.tt/ejFOUZr via IFTTT

I had to kill bitcoind, then deleted my datadir and restarted bitcoind. I assumed it would recreate and resync everything, which it did, except for the (empty) wallet.dat. What I did was delete the separate datadir, empty the .bitcoin folder, except for the bitcoin.conf file containing my rpf credentials. I tried twice, the second time orderly stopping and restarting bitcoind, but without a new wallet.dat recreated. What should I do get a new wallet.dat, preferably through a fresh restart (to avoid carrying over any file corruptions as a consequence of unorderly killing the daemon process)? from Recent Questions - Bitcoin Stack Exchange https://ift.tt/lD62n5T via IFTTT

As I understand it, policy rules in Bitcoin are primarily designed to prevent other users from abusing node resources. However, what if we introduced a proof-of-work requirement for transactions that are currently considered non-standard? The idea is that requiring PoW for such transactions would impose a cost on users attempting to relay them, potentially reducing abuse. Would this approach be feasible or beneficial? The goal would be to create a more accurate and inclusive mempool view. Currently, non-standard transactions are sometimes included in blocks, but because regular nodes don't relay them, they aren't visible in most mempools. Could a PoW requirement help standard nodes relay these transactions while still deterring abuse? from Recent Questions - Bitcoin Stack Exchange https://ift.tt/RgjZW6I via IFTTT

One of the main possibilities that SigHash SINGLE | ANY (0x83) has, is to combine two or more transactions with this particular flag into one (Modularity). That's the theory, but when it comes to practice, it is not working (at least for me); Let me explain: I created this two transactions in testnet4, both spending only one input and sending it to only one output, both P2PKH: Transaction 1: 0100000001bd20399c1f2d841f1e147ad2e03df1635f48fc5b8cdbb55ea3a86b14225e2743000000006a4730440220435c5161232d1b3215c44169f7c0328f1af1d40b4a8f2ec16795f442e9b80f7e022047fd3dd15421d2a0956a79e2141f3a72d2fe69c4e6c5bcc75047bd6d8bf019f5832102313b35fdf7af967980d29e684c508c90e11d99b10cab20ef477c9e63d9bf7bf7ffffffff0158980000000000001976a914c103e57c094061209b419e5ca559704a8a22f3f988ac00000000 Transaction 2: 0100000001d38e64afa39dd966f96e07bf56ae44bc3d402630771480f461389edff8a0051e010000006a4730440220645a7a25ebb00194a3b2f940d5618d021f513c2dd9bdc0504f623824e9845d8e0220077af01808e98b7ca97d2927243f9beb8cb...

I am trying to track transactions in the mempool that utilize Replace-By-Fee (RBF). My approach involves saving the current transactions in the mempool and comparing them to newly added transactions. If a new transaction shares inputs with a previously saved transaction, I infer that it replaced the original transaction via RBF. In such cases, I save both the original and the replacement transactions for further analysis. My question is, if instead of doing all this, is there any method in which the Bitcoin core to tell me when a transaction has used RBF. from Recent Questions - Bitcoin Stack Exchange https://ift.tt/xPaeGDb via IFTTT

I'm trying to understand how Lightning works by running tests using Bitcoin Core on my local machine in REGTEST mode together with running two LND Lightning nodes (let's call them the classic Bob & Alice) on separate localhost ports too. I'm using bitcoin-cli and lncli to interface with the nodes. I made Alice's LN connect to Bob's LN and opened a channel between them with an initial capacity of 10,000,000 sats, funded by Alice's chain wallet, and included a --pushamt of 35,000 sats to Bob's LN in order to create some inbound liquidity. This all seemed to have worked just fine and as expected, and the funding transaction into a 2of2 Multisig covering the channel was added into the blockchain too (6 confirmations). However, something's nevertheless wrong. Despite Alice having sent out BTC on the channel, Bob cannot send any of that BTC back to Alice! I even had Bob send Alice an invoice for another 5,000 sats, but nothing changed after she paid ...

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/qWLgB9D via IFTTT
