In the non-segwit case, FindAndDelete removes signature data from scriptCode. In P2PKH, the signature is not included in the scriptPubKey, so I think the only thing that may actually have signature data removed by FindAndDelete is redeemScript for P2SH. But is there actually a useful use case for including a valid signature within a redeemScript? What was the intention behind introducing the FindAndDelete process? In the following Bitcoin Core's FindAndDelete test case, the public key is recovered from the signature and set to scriptSig. https://github.com/bitcoin/bitcoin/blob/v28.0/src/test/data/tx_valid.json#L496 from Recent Questions - Bitcoin Stack Exchange https://ift.tt/O87x6As via IFTTT

It is reported that an attack on Substitution-Permutation Network (SPN) has been developed with the currently available quantum annealing system from D-wave, as reported in the mostly Chinese paper : The Reg understands the research team, led by Wang Chao from Shanghai University, used a D-Wave machine to attack Substitution-Permutation Network (SPN) structured algorithms that perform a series of mathematical operations to encrypt info. SPN techniques are at the heart of the Advanced Encryption Standard (AES) – one of the most widely used encryption standards. The tech targeted in the attack include the Present and Rectangle algorithms, and the Gift-64 block cipher, and per the Post produced results that the authors presented as “the first time that a real quantum computer has posed a real and substantial threat to multiple full-scale SPN structured algorithms in use today.” Is this a real world practical threat today, or in the near future?

Are IDs, IPs, or onion addresses of nodes with whom lightning service providers had issues, e.g. force-closures, shared between many different lightning service providers?

I recently read that China was able to use quantum computer for cracking military grade encryption. https://thequantuminsider.com/2024/10/11/chinese-scientists-report-using-quantum-computer-to-hack-military-grade-encryption/ The article does admit that the present quantum capability is still in its infancy to affect banks and other services. But let's say that they are able to advance quantum computing to the extent that they can crack into banks and military. How safe is today's blockchain from such future quantum developments?

I think I understand the purpose of a blind oracle: to not have our encryption key stored in Jade so that an attacker can't perform a physical key extraction by manipulating the hardware. The oracle serves as a form of "secure element" and helps keep Jade fully open-source by being in an external server. We can get the secret key to unlock the wallet using an Elliptic Curve Diffie-Hellman (ECDH) key exchange, which is only available after we set the PIN correctly. However, I don't understand how is the PIN itself secured. Question: Wouldn't the PIN be subject to the type of key extraction the oracle is supposed to protect us from, since it is not stored in a secure element? If yes, sounds like getting the PIN would be just an additional step, but once the attacker has it, he is capable of obtaining the secret key by performing the ECDH himself, which doesn't sound much safer. Can someone explain to me what I'm getting wrong here? Thanks! from Re

I want to lock funds in Bitcoin using a transaction and include some additional structured data (let's say a struct with several fields). The locked amount should remain unchangeable, but I want to later update certain fields within the struct without modifying the locked amount. Is it possible to construct a Bitcoin transaction that allows locking funds while also posting some additional data? And more importantly, can the fields of this data structure be modified in later transactions without affecting the locked funds? What would be the best approach to achieve this? from Recent Questions - Bitcoin Stack Exchange https://ift.tt/muDyOd1 via IFTTT

Total noob in crypto (bought my first few mBTCs a month back) and a proud owner of a new trezor one hardware wallet. I want to ask what’s the most direct/frictionless way to get the bitcoins into my Trezor? I have already set up my wallet and did my first transfer into it, it worked. But I had to first sign up and buy the coins via independent reserve, and then transfer it to my wallet address. The independent reserve charged me when I paid my dollars into their account (paid $500, they credited something like $497), then they charged me a few satoshis when I transferred from that exchange to my trezor. Seems very convoluted. Is there a more direct way, without going through these extra transfers? Related, the trezor one suite (I am using the Linux Deb version) has an address in it, along with a QR code. Is it safe to keep a copy of this QR code on my phone, and flash it at a bitcoin ATM (or share it via whatsapp to any sender) to receive Bitcoin? Will the ATM send it directly to my

I am interested in how transactions are transmitted, processed, evaluated and finally being accepted. I was reading the source code and noticed that there are "AcceptSingleTransaction" and "AcceptMultipleTransactions" functions. The latter is called only in "AcceptPackage" and "ProcessNewPackage" functions but it seems that that is where the chain of events end. The "ProcessNewPackage" function is used only for JSON RPC mempool acceptance testing and Regtest. I don't think this function is used for Bitcoin mainnet. Q1 => Do every single transactions in Bitcoin mainnet go through "ProcessTransaction" -> "AcceptToMemoryPool" -> "AcceptSingleTransaction"? Q2 => If the answer for Q1 is yes, then isn't it kind of inefficient? Is "AcceptMultipleTransactions" deprecated? from Recent Questions - Bitcoin Stack Exchange https://ift.tt/JYg06my via IFTTT

With the rapid advancements in quantum computing, the cryptographic algorithms securing Bitcoin may soon be vulnerable. Delaying the implementation of post-quantum cryptography could expose Bitcoin to significant risks, especially if quantum capabilities are achieved sooner than expected. Qbits is capable of implementing post-quantum cryptography (PQC) as per NIST recommendations, ensuring that Bitcoin remains secure against quantum attacks. We have conducted successful experiments, as detailed in our project: Bitcoin on Quantum Computing. For more context, here’s a recent post on our progress: Qbits Post on LinkedIn. What are the potential obstacles or considerations in implementing PQC for Bitcoin now, and how can the community help make this transition smoother? from Recent Questions - Bitcoin Stack Exchange https://ift.tt/76oG3JO via IFTTT

Let's imagine someone sent BTC to another person who aggregated it and sent to my friend. Can they trace the BTC back to the original sender. Some of the BTC was sent from exchanges at different stages of the transaction but some was bought from bitcoin ATMs, some from other people using different wallets ( exchanges, trust wallets, Blockchain etc) . How far back can authorities trace . Some was sent directly to the friends wallet, others were added to other purchases BTC and sent , from Recent Questions - Bitcoin Stack Exchange https://ift.tt/x6oUcCg via IFTTT
