LBANK INFO CRYPTOCURRENCY

When it comes to crypto loss. As a 'tech personal reasonably informed about cryptocurrency, I concur that it is highly unlikely that you will ever recover any money. Most platform claiming they can help you are all birds of same feathers, few people that has successfully recover their crypto back has been scammed Multiple times, if you're not experienced you might fall victim like everyone. you can avoid been scammed and if you're already a victim by learning from the mistake of others and get help from a reliable sources like easyrecoveryassets@gmailcom your money will be recovered. the amazing part is they don't charge before recovering from Recent Questions - Bitcoin Stack Exchange https://ift.tt/dwtbym7 via IFTTT

As per BIP341 [https://ift.tt/baG6VWT]: "First, we define taproot_tweak_pubkey for 32-byte BIP340 public key arrays. The function returns a bit indicating the tweaked public key's Y coordinate as well as the public key byte array. The parity bit will be required for spending the output with a script path. " This is shown in the "Script validation rules" section: If q ≠ x(Q) or c[0] & 1 ≠ y(Q) mod 2, fail [10] Following the reference [10]: "Why is it necessary to reveal a bit in a script path spend and check that it matches the parity of the Y coordinate of Q? The parity of the Y coordinate is necessary to lift the X coordinate q to a unique point. While this is not strictly necessary for verifying the taproot commitment as described above, it is necessary to allow batch verification. Alternatively, Q could be forced to have an even Y coordinate, but that would require retrying with different internal public keys (or different messages) unt...

We thought about buying bitcoins, but we are total noobs and the whole topic is very complex and there are lots of confusing instructions trying to sell some service. The main idea was to buy the coins anonymous on the private market, for example selling a car for bitcoins. Also important is the security aspect, so storage of the coins should be offline and not on a server or desktop machine. So the following questions arise: What tools can we use to trade with bitcoins. Not interested in apps or services that make it easier, etc. Libraries for python etc sound too complicated, too. Is there maybe an official bitcoin tool for linux? If somebody offers us a bitcoin, how can we validate, that the coin is real? How do you transfer the coin to another person? How can you make sure that the transfer worked? How do you know the seller cannot sell it to another person. Where do you store the coin? Is a wallet needed? How big is the data in bytes/octets? What format could be ...

I have a Core Lightning node with multiple closed channel outputs, and I don't wish to open new channels with these. For backup reasons and for ease of use of the Bitcoin Core user interface I'd like to export these outputs and import them into a Bitcoin Core wallet. I tried exporting the on chain descriptor using hsmtool --dumponchaindescriptors --show-secrets and importing it into Bitcoin Core using bitcoin-cli importdescriptors , but it seems that the private keys for closed channels are calculated using a complicated combination of information related to the lightning node which are not available from the descriptors alone (see https://bitcoin.stackexchange.com/a/90719 ). How can I export the private keys of each individual on chain fund output so that I can import them into Bitcoin Core? from Recent Questions - Bitcoin Stack Exchange https://ift.tt/O8lsoqe via IFTTT

RBF rule #3 states: The replacement transaction pays an absolute fee of at least the sum paid by the original transactions. ( https://github.com/bitcoin/bips/blob/master/bip-0125.mediawiki#implementation-details ) The rationale for implementing this rule in Bitcoin Core's mempool policy is described as follows in the mempool-policy.md document: Rationale: Only requiring the replacement transaction to have a higher feerate could allow an attacker to bypass node minimum relay feerate requirements and cause the network to repeatedly relay slightly smaller replacement transactions without adding any more fees. Additionally, if any of the original transactions would be included in the next block assembled by an economically rational miner, a replacement policy allowing the replacement transaction to decrease the absolute fees in the next block would be incentive-incompatible.

I understand why a pruned node will fail to load a wallet file that's too old (i.e. a wallet whose last witnessed block occurs prior to the earliest available block in the pruned node's history). I gather when attempting to do so you get "Error: Prune: last wallet synchronisation goes beyond pruneddata". However, I noticed the same error being displayed when trying to load a wallet.dat file that last witnessed a future block which the pruned node hasn't yet seen. I'm wondering why it can't simply download (and discard as appropriate) blocks up to the one the wallet last witnessed, then continue marching on from there? A sequence to reproduce the behavior goes like this (for simplicity, no transactions affecting the wallet took place between steps): Take wallet.dat from a pruned node that hasn't been synced in a long time, and move it to the environment of a full node. Fire up the full node and let it sync. The wallet.dat file will get modif...

The early, now called "legacy", multi-sig didn't really have a standard for derivation as I understand. For example contrarily to native segwit multisig, where m/48'/0'/0'/2' seems used by default by pretty much every software and hardware wallet. So for example Electrum, if I'm not mistaken, uses m/45'/0 for legacy multisig while a hardware wallet like the Keystone used m/45' . As a sidenote apparently on the Keystone hardware wallet I cannot even export any "xPub" other than m/45' for Legacy P2SH multi-sig. I know you can (and I already did) use native segwit multisig but this is not what I'm asking here. What I want to know is if legacy multisig using m/45' is safe? For example in a 2-of-3 or even 3-of-3 multisig. Would there be any security issue or considerations? Several wallets (including Copay, Electrum, Sparrow too I think) aren't using that path by default anymore. Is it because it's unsafe? f...

Bolt 7 says DNS hostnames (type 5) in the addresses field of the node_announcement gossip message have to be ascii encoded and non-ascii characters have to be Punycode encoded. However, to my understanding, it would only make sense to encode the whole string either in ASCII or Punycode. If the hostname is encoded in ASCII and only single, non-ascii characters are encoded in Punycode, the receiver would decode it as ascii and get a different hostname (as punycode is valid ascii). Encoding every hostname in Punycode would result in every string having a hyphen postfix: example.com-, which would probably also be interpreted wrong by receivers as the bolt says it has to be valid ASCII (not Punycode).

I have three questions with regard to replay protection. Q1 => Some non-standard scripts (like x + 2 = 5) do not require signatures (so naturally no SIGHASH_FORKID ) to spend the UTXOs. Are these UTXOs and transactions still prone to replays? Q2 => I have read the documents from the inception of Bitcoin Cash and realized that the legacy transaction digest algorithm is not being used anymore. From my understanding, the 4-byte sighash type is appened at the rear of the digested transaction input (Both for SigVersion::BASE and SigVersion::WITNESS_V0) and if a unique sighash flag is used, the uint256 SignatureHash result would be completely different. The SignatureHash function in the src/script/interpreter.cpp file of Bitcoin Cash only allows BIP-143 digest algorithm when SIGHASH_FORKID is in use. What if Bitcoin Cash developers only enforced the use of SIGHASH_FORKID and embraced Segwit? Is a unique sighash flag not enough to prevent replays? Q3 => If a unique sighash fl...

As I currently understand P2TR scripts do not hash the public key like P2PKH (RMD160) or P2WSH (SHA256). In P2TR the there is just a public key encoded in bech32m, basically making it the same as P2PK? If true, is this so people can do musig and tweaked public key scripts?

We know that Schnorr signature is applied this way: Key Generation Define curve ( E ), field ( F_q ), order ( N ), generator ( G ), and hash ( h ). Private key: ( d in (0, N) ), Public key: ( P = dG ). Signing Random ( k in (1, N) ), compute ( R = kG ). ( c = h(R || M) ), ( s = (k + d * c) % N ). Signature: ( (R, s) ). Verification Compute ( c = h(R || M) ) and check ( sG = R + cP ). Valid if true. Related-key attack: A Related Key Attack targets the Schnorr signature scheme by exploiting additive modifications to public keys. If an attacker has a valid signature ( (R, s) ) for a public key ( P ), they can generate another valid signature ( (R, s + ac) ) for a related public key ( P + aG ), where ( a ) is a scalar. Thus, public keys generated via additive changes are vulnerable, as the attacker can forge valid signatures. My doubt What I don't understand is how this attack works in a real scenario. What should an attacker actually do? The attacker must hope to...

I have started learning the bitcoin blockchain from the technical perspective and while lots of things do make sense to me immediately, I am somewhat confused about some details about the proof of work concept. Namely, in the current implementation to successfuly mine the block one is required to find the number (nonce) such that the hash(block, nonce) returns n leading zeros. This n is chosen by the network in such a way that hashpower of the network produces one block every T = 10 minutes . My question is: what if this system had lower T ? My guess is: the lower the T the higher is the risk - but the risk of what and why? For example, which undesirable situation is much likely to happen in case T is just 1 second? The answers I have seen so far that remotely seem to address this question: in case of bigger T it is harder for the attacker to come up with the longest chain that will convince the network of his version of the history. But this argument does not appeal to me: if T...

TLDR: Can someone lead me through the process of running a Bitcoin Full Node on a Raspberry Pi 5 with Raspberry Pi OS (64-bit), which does not display my IP adress openly (so probably via TOR) and explain me the whole thing about portforwarding and how to minimize risk with it? I would like to run a Bitcoin Full Node on my Raspberry Pi 5 running Raspberry Pi OS (64-bit). The Pi is booted from an external 2TB SSD which, before imaging the OS, I formated to ext4 and on which I would run the whole node. The Pi is only intended for running a full node. Even though the Pi is only connected to my guest wifi, I would like to not display the IP adress openly, so I would like to run it via Tor.

In the blink of an eye, my entire world was turned upside down. A hacker gained access to my iPad, and before I could even process what was happening, they had breached my Binance account and bank account. Within minutes, they swiftly changed the bank details on my Binance account, transferring over 4 Bitcoin into their own wallet. To make matters worse, they drained nearly $287,000 from my bank account. I was in complete shock, unable to comprehend the magnitude of what had just occurred. Desperate to recover my funds, I immediately contacted Bianca support. I spent hours on the phone with them, explaining the situation and hoping for some resolution. However, despite all my efforts, I was met with little help or progress. I also reached out to my bank, but after even more frustrating conversations, I was left with no choice but to shut down my account and open a new one. But despite taking all these steps, my stolen funds remained unrecovered. The self-recovery option on Bianca didn’...

We have a test Bitcoin network deployed that behaves as the Mainnet but obviously with much shorter chain and less PoW. This mainnet has been created using https://github.com/NiktowCode/BTC-Labnet tool. In this network we have a dockerized Electrum server using https://github.com/spesmilo/electrumx implementation. The server is fully functional as other wallets, such as my Electrum client, after modifying the source code to remove some verifications, are able to connect to it, send and receive transactions and validate everything. The issue is, I want to use Trezor Suite in this test environment for academic and research purposes, but when I go to "Customize Backend" and enter the server's IP, port and protocol, I receive the message indicating that connection cannot be established. Does anyone know whether Trezor Suite checks chain length, amount of PoW or similar, and if it does not match a certain minimum it refuses to establish connection? Thanks in advance. from...

Let's say we set a secret key integer to be P itself and get the corresponding public point coordinates, X and Y. Let's say we set another secret key integer to be 100 and also get the public point, X and Y We can perform point addition on these points and get a resulting point, let's call it (X_res, Y_res). Working from this simple example, how can we get the integer value of the secret key that has (X_res, Y_res) as a public point? For example, if we do a simpler point addition on the public points that correspond to the secret key integers of 5 and 3, we see that the resulting point is equal to the public point of the secret integer is 8. This agreement between integer space additions and X,Y coordinate point additions seems to not work when the secret key sum (in regular integer space) exceeds P. from Recent Questions - Bitcoin Stack Exchange https://ift.tt/9Aczm4K via IFTTT

If the Shor quantum algorithm like Shor, which is capable of cracking Bitcoin addresses, is implemented in the future(like in 2040 or 2140 ...), what will be the Bitcoin community's attitude towards “lost addresses”?
