BTTUSERNAMEActually mobile OS usually have better security by default compared with desktop OS. For example, Android offer Application and Privacy sandbox which limit what an application can do.
That's correct. There are not much hacks that happen because of vulnerabilities present in OS but because of negligence of people. There is no way a malware can make it to your mobile unless you download some fishy app or click on some suspicious link. Rather then focusing on security of devices alone, human vigilance is also required in cyber world (or securing bitcoins).
A chain is as strong as it's weakest link, and in security of Bitcoins the weakest link is human.
It seems your major concern is basically on human vigilance. But we can all agree that, inasmuch as human vigilance and carefulness is essential when it comes to Bitcoin security, the technological advancement in Blockchain security plays a more vital role when it comes to Bitcoin security because there are so many measures provided to enhance security even when humans are not being super careful it'll be difficult for scammers and hackers to exploit them. Let's consider the Zero knowledge proofs and the multi-signature wallets for example. If you're familiar with these technologies then you'll know that these techniques makes it almost impossible for scammers and hackers to access people's wallets.
We can equally consider development and advancements in encryption and cryptography. They are also quite helpful techniques that helps to secure the bitcoin wallet. I'm not saying Human vigilance isn't important or essential, but I stand to believe that it's not the primary as there are things that are more important.
1. Long and generic reply.
2. Zero knowledge proof basically a method to verify the data without knowing the data itself. I don't know why it's mentioned as method to secure wallet.
3. Encryption is part of cryptography.
4. Bitcoin wallet usually already use strong encryption cryptography (usually AES-256), assuming the user doesn't use weak password.
Electrum uses third-party servers for its work, and this is a potential attack vector.
I've never read about an attack by giving fake block information or something. The only thing I've seen is a server telling the user to download malware.
You are completely accurate, but I would like to offer an alternative viewpoint on this. It is true that there have been no known occurrences of a block chain attack using fake block information, but I do not believe this is sufficient evidence to conclude that such an assault is impossible. For example, if an extensive group of hackers had control over the majority of the computational power in a blockchain network, they could hypothetically generate a false history of transactions, causing widespread confusion and potentially undermining the network. Although this may be considered to be a theoretical attack, it should still be considered seriously, and I do not believe we should dismiss the likelihood of such an attack simply because it has not yet been observed in the wild.
1. Fake block doesn't make sense here. If it's fake, it would be rejected by node and thus won't be propagated across Bitcoin network.
2. Performing 51% attack on Bitcoin is very expensive and generally seen as not probable attack. So average people don't have to consider this attack vector seriously.
3. If 51% attack actuall happen, which Bitcoin wallet someone use doesn't matter here.
4. 51% attack still require the attacker to create valid transaction and block, so term "false history of transaction" doesn't make sense here.
5. This reply is off-topic since the thread title is "Why can't I retrieve the private key for my bitcoincore wallet address?".
if an extensive group of hackers had control over the majority of the computational power in a blockchain network
In the scenario of a 51% attack, neither Bitcoin Core nor Electrum is going to help you.
A 51% attack would undoubtedly pose quite a serious problem for any Blockchain, regardless of the software used to access it. As a matter of fact, both Electrum and Bitcoin Core are only designed to operate on an assumption that the underlying Blockchain is secure, but that doesn't mean they provide an assurance for security of the Blockchain from external attacks.
You're right that If eventually a 51% attack were to occur right now, both of the softwares wont guarantee user's safety or be able to protect users from the potential consequences.
But looking at it from a contrary POV, even if the softwares can't guarantee user's safety, they still won't be utterly useless in a scenario of a 51% attack, because even if the Blockchain itself was compromised, these softwares could still be used to track transactions and also verify balances. These services could stil be quite valuable to users despite the fact that they don't guarantee user's safety.
1. Saying Bitcoin Core works under assumption blockchain is secure is wrong. Bitcoin Core verify all block/TX while also can detect block reorganization.
2. Unless user send Bitcoin or expect to receive Bitcoin when 51% attack happen, there's no need to check balance or newly created transaction.
3. This reply is off-topic since the thread title is "Why can't I retrieve the private key for my bitcoincore wallet address?".
Hi,
I have been using blockchain.com wallet to receive crypto payments without any issue since years, though in this month, the BTC deposits (funds received) in our blockchain.com wallet were all showing as normal till 6th, but today once I try to send some funds out from my BTC wallet (its still showing balance fine, and $0 in hold funds, means all funds are showing fine as balance in BTC wallet), the available balance showing was only like $30 worth of BTC, again i try to open the wallet via web (instead of andriod), but same thing, funds are showing fine as balance in the BTC wallet, but once i try to send them out in available balance they show almost none.
Any help? I have already contacted blockchain.com via their support ticket system.
Thanks.
Sorry about that Mate.
I can remember a friend of mine was having similar case some time ago, some amount of BTC was sent into his Blockchain wallet, the BTC balance appeared fine just as you stated but whenever he tried to initiate a transaction, an error message would pop up, saying there's no BTC in his Blockchain wallet. Although his own case was slightly different from yours because it was a new wallet he opened specifically for that transaction.
After much inquiries, we discovered the BTC sent to his wallet wasn't a real one, regardless of the fact that the balance was fully loaded, that was all he had, a balance load of BTC and nothing more because the BTC there was as good as worthless, they said they called it BTC balance flash, something like that.
But since you said you've been using your wallet for years now and the bitcoin was received from a trusted person, then it's possible the problem could be from blockchain.com's database. It could also be possible that there's a bug in the wallet software that's probably causing the issue so I'll recommend using your wallet from a different device or maybe you could try to reset your wallet.
You can equally just wait for Blockchain.com's reply since you've already contacted them.
1. The only somewhat helpful information is waiting for blockchain.com's reply.
2. I did quick search for term "BTC balance flash", but didn't find any relevant result. Although based on his explanation, it's probably his friend got fooled by watch only wallet.
