When sending Bitcoin from my computer, how does my computer know which computers to send this transaction for verification? Where are the addresses of these broadcasting computers stored?

[@sergeos]

I don't understand this, everybody keeps talking 'keep your seed phrase safe', 'keep your private key safe', 'don't share them with anyone', but, to SEND crypto one needs to SHARE the keys with the wallet right And the wallet is software based. Even a hardware based wallet has software in it. I heard the crypto ecosystem nowadays is like 'wild wild west' not regulated or anything. I think the main cryptocommodity is trust. People trust people they'll do the right thing and then boom, someone makes a video that their crypo assets have been stolen. Even the paper wallet with the QR code, gotta show it to the camera on your phone or mobile, right?

[@noshadb.e3111]

i wonder if you are satochi nakomoto him self?

[@JM-tu8mg]

If the mining is becoming harder and harder, does that also indicate that less transactions will be confirmed?

[@99Bitcoins]

Hey JM, As the difficulty of mining Bitcoin increases, it generally takes more computational power and resources to successfully mine a block and add it to the blockchain. This means that the rate at which new blocks are added to the blockchain will decrease, which can result in a slower confirmation time for transactions. However, this is not a direct correlation and the confirmation time also depends on the number of transactions being sent, the fees attached to them and the current state of the network.

Thankyou!!

Do all miners try to solve the same block? Or can it be that each miner has a different set of transactions in their block?

[@genglai5041]

Hi i have an enquiry: I had made a first withdrawal via a unique payment Network address. After that, i accidentally copy pasted the same network address for my second transaction which is made payable to the same company. The company has informed me that they did not receive the coin even though the withdrawal was successful from my wallet. 1) is my coin gone? 2) is there anyway to retrieve it?

[@Ghanzo]

What causes the sig to differ each time? This did clear up a lot for me. Have you ever thought about an analog wallet machine? It would generate addresses and signatures mechanically. What do you think about this? Possible? The highest standard of security?

[@slavkosster]

The signature is different every time, because no two transactions can have the same set of inputs and outputs, and the signature is a hash of the entire transaction content.

[@thesharanaithal]

You said we've to wait for 6 transaction confirmations to know that it's legit. How can there be any cancellation in the first place once the transaction goes into the block?

[@99Bitcoins]

6 blocks is usually recommended as a good tradeoff between certainty and convenience. You can wait less if it's a small / unimportant transaction or longer if it's a large / important transaction. Due to the Bitcoin network's decentralized nature, it's possible for chain re-organisations to occur. This is why it's recommended to wait. What happens during a re-org is that miners solve a block at roughly the same time then both transmit their solution to the network. Some nodes will see the next valid block as coming from miner 1, others from miner 2. The network will then be divided between these two competing chains. The way this situation resolves is that the chain which finds a new block first becomes "more valid" than the slower chain, as Bitcoin clients are designed to recognise the chain with the most accumulated proof of work as the real chain. The chances of a re-org occurring after 6 blocks (roughly one hour on average) are very low and go lower with more time, which is why it's considered a safe waiting period.

Probably this'll not happen until there will be no "block rewards" or "transaction fee" Included with transaction. If there were very few miners as of 2009, the mining difficulty will be reduced to a large extent and we are able to mine BTC with a CPU. Yes, it takes days for a transaction to enter a Blockchain but this is very rare.

[@99Bitcoins]

Hello Carmela, Before you buy Bitcoin, you first find a wallet that you'll deposit the coins into. There are many types of wallets you can use. I suggest looking for the most popular ones on this page: 99bitcoins.com/best-bitcoin-wallet-comparison-review/ The Bitcoin you bought will be sent into your wallet. From there, you can choose what to do with the coins. You can keep them for later, or send it to a friend's wallet (if they buy it from you), or spend it online, or exchange the Bitcoin into other cryptocurrencies. I hope this helps!

[@kimchau8647]

[@neemasiraji2947]

Has is ever happen that a transaction was never confirmed and the bitcoins did not return to its original address?

[@99Bitcoins]

Not to my knowledge, no. Although transactions do fail to confirm, usually because they paid an insufficient fee during times of network congestion, eventually the transaction is simply "forgotten" by the network - or drops out the mempool - and the coins are returned to the sender. There are also more sophisticated ways of dealing with such stuck transactions, such as Replace By Fee (RBF) which allows the transaction to be resent with a higher fee if that option is supported and enabled in the sender's wallet. Child Pays For Parent is another way to resolve this issue, by sending a transaction with a sufficient fee which is contingent on the original being mined.

[@blaze9558]

[@99Bitcoins]

Hi @Blaze, nice to meet you! Whenever the number of miners goes down, it becomes much easier for them to earn the new coins mined. No transactions will pile up and stay pending as long as there are miners in the network!

[@leandrobianda8857]

thank you, very clear! :)

[@bluex217]

Thank you, that did help my understanding! The 1 question I leave this video with is this: So, I understand that for an "average" person to invest in crypto, they pay a transaction fee in hopes of miners and their software picking their transaction, and then the "golden nonce" being found within a block on the blockchain for which their transaction resides. If your transaction is picked, then it's essentially analogous to spinning the wheel or running the slot machine in a way... However, what confuses that concept to me is your scenario in the beginning when you simply want to "send 1 bitcoin to your friend Steve." This no longer seems like investing to me, this seems more comparable to transferring money from 1 bank to another, yet, we utilize the same, probability based approach whereby you won't have any probability to transfer money to your friend Steve if the fee is too low, and therefore miners don't ever pick your transaction. This just seems like an overly complicated and inapplicable approach for transferring something. Surely there is a less "casino" approach to simply transferring crypto? Or is there something I'm missing?

[@loc4725]

The fee is used as an incentive to encourage 'miners' to verify the transactions, so in a way it is a kind of lottery as there is a natural limit to how many blocks can be created. In reality though the fee simply increases the probability vs. time of your transaction being confirmed. A low fee doesn't exclude you but does decrease the probability of confirmation in any given minute; your transaction will most likely still go though but you will have to repeatedly 'spin the wheel' (i.e. wait longer) for your number / confirmation to come up.

[@bluex217]

@@loc4725 Thanks so much for confirming this for me :) Got it.. from what I've read even with a low fee it's still quicker than wire transfer or check processing lol

[@loc4725]

@@bluex217 No worries. 🙂 I would also say there is one caveat though now you mention it. The probability of your transaction being confirmed is likely to be dramatically reduced in the event of a Bitcoin 'run'. A spike in transactions is likely to overwhelm the system and additionally drive up the fee as people scramble to liquidate and attempt to outbid each other for confirmation. It's just something to think about as I know a lot of people, myself included, are thinking about buying during this dip / panic.

Hello @Lior, Thank you for your question. These are two different processes. The UTXO model is what ensures that the sender has the exact balance remaining in his wallet, after sending a portion of his coins. The blockchain nodes confirm that the ledger is updated with the transactions. They ensure that the most accurate account of who owns what is broadcasted so that the transactions are done transparently. I hope this helps!

How exactly the miners verify that the transaction is valid? What exactly they checking?

[@incredulity]

They're checking whether the sender has enough money for the transaction, whether digital sig. matches the sender, etc.

[@99Bitcoins]

The miners (and nodes which pass transactions on to miners) will check that a transaction follows the system's rules. The full blockchain shows the complete record of every amount which has either been mined into existence or moved from one address to another over time. By checking each step (and if a transaction is recorded in the chain, it's taken as valid as there's no other authoritative record of which transactions are valid) in the movement of value, one reaches a set of all the addresses currently holding spendable value (the UTXO set). Miners will check that any address attempting to send value is part of that UTXO set, owns enough Bitcoin to cover its intended transaction, and isn't trying to send the same coins to multiple addresses at once (if so, only one transaction will be chosen and once that gets mined, the other attempts will be considered invalid). These are the general sorts of things which get checked.

Hi @Pat Walker, Since all Bitcoin addresses have a similar format of a random string of letters and numbers (they all start with 1 or 3), it is quite difficult to guess the exchange or wallet address correctly. With some advanced skills, it is possible to cross-reference addresses using a blockchain explorer like blockchain.com. However, even after finding out the right details, it would be much harder to trace the person who holds that wallet. It may not be worth the effort to search for the wallet in the first place.

Crypto exchanges use the same kind of wallets for deposit and withdrawal as users do. When an exchange sends your coins to your private wallet, that transaction goes through the blockchain as per usual, just like when you send coins to your exchange address. While your coins are in the exchange, things are a little different. They use an internal ledger to keep track of user trading, as that doesn't need to go on the blockchain, and would be too slow to do that way.
