Here's a quick video demonstrating how to send Bitcoin in the Bitcoin. Read more: Learn how to receive bitcoin securely. Many Bitcoin wallets including the Bitcoin. Bitcoin transactions incur a small fee which is paid to the miners that confirm them. Transactions with higher fees attached to them are picked up sooner by miners who optimize for profitability , so higher-fee transactions are more likely to be included in the next batch, or 'block,' of transactions that's added to the Bitcoin blockchain.
This means you can opt for faster transaction processing by paying a higher fee. Alternatively, if you're not in a rush to have your transaction confirmed, you can save money by opting for a lower fee. However, you need to be careful because if you set the fee too low, your transaction may take hours or get stuck for days.
Don't worry though, you're never in danger of losing bitcoin by setting the fee too low. In the worst case, you'll have to wait 72 hours with your bitcoin in limbo until the transaction is cancelled, at which point you'll again have access to it. A satoshi is the smallest divisible unit of bitcoin, which is 0.
Each transaction is made up of data, which is measured in bytes. More complicated transactions involve more data and so are more expensive. Generally speaking, this means higher value transactions involving more bitcoin consume more data, and so require higher transaction fees. However, it's not exactly that simple. In fact, it's entirely possible for a 1 BTC transaction to involve more data and therefore require higher fees than a 0.
To understand why, we need to look in some detail at how the Bitcoin blockchain actually works. The system runs on what's known as the Unspent Transaction Output UTXO model, which is an efficient and privacy-enhancing way to manage the Bitcoin ledger. It works like this:. At first, coins are minted through the mining process. These new coins form what's known as the 'coinbase. On the ledger, this actually appears as 6. In our example, the miner has sent over a 6. As it relates to fees, even though the amount of Bitcoin involved is significant, the fee for completing the transaction will be relatively small because the transaction is relatively simple.
That's because there's only one output 1 BTC to Alice and it comes from only one input or 'note' the 6. If we think of notes as taking up space on the Bitcoin ledger, we can see that this transaction takes up the least amount of space bytes possible. Now let's imagine Alice buys one more BTC at a later date from a different miner. Alice will then have 2 BTC in her wallet, but each one will have originated from different 'notes. For the average user, this means you'll end up paying significantly more for a transaction if it involves moving many 'notes.
Now, if you want to send that one bitcoin to someone else, you'll actually be sending 'notes. This, again, depends on the wallet. In fact, many web wallets cryptocurrency exchanges don't give you any control over the network fee whatsoever. Instead, they have a predetermined fee which is almost always set higher than the actual fees they will pay.
Many Coinbase users behave like investors and never leave the app, but there are many instances where you need to send coins elsewhere. With a reputable verification process, Coinbase is well-known for its compliance with large banks like Bank of America, Wells Fargo and Chase. This allows everyday users to purchase crypto with a low barrier to entry. Bitcoin is a new currency created in by the anonymous developer Satoshi Nakamoto.
In other words, two parties can transact goods and services without the need for a bank. Over time, Bitcoin has become more practical for real-world transactions. You can now use Bitcoin to purchase just about anything: a vacation getaway, Xbox games, a pair of shoes, even pizza.
And more companies are hopping on the crypto bandwagon every day. A lot of the media hype also comes from the wealth opportunities that exist when trading it. Because Bitcoin is so volatile, price speculators can make and lose big bucks on coin exchanges.
Coinbase is a popular software tool that enables you to buy, sell and exchange cryptocurrency. They have a mobile app and web interface where virtually anyone with a bank account can access a wide range of available cryptocurrencies. Coinbase was founded in as a small startup in California, but has quickly become the largest cryptocurrency exchange in the United States by trade volume. As mentioned, their coin exchange is widely popular due to its low barrier to entry for new users.
Many large US banks were initially hesitant to allow the purchase of Bitcoin, making it difficult for newbies to get started. Coinbase and other popular exchanges with compliant KYC protocols allow just about anyone to get skin in the game. Setting up your Coinbase account is easy! You can download the app on iOS or Android, or you can make an account online. To set up an account, first create an email address and password.
Coinbase may also ask you about your risk tolerance and how you plan to use their service. Once your account is created and you verify your identity on Coinbase, you can then buy coins with a debit card, bank transfer or wire. These differ depending on your location. Typically linking your bank account is the quickest way to get things up and running. With your bank account hooked in, you can now buy popular coins like Bitcoin or Ether. Now that you have coins in your wallet, you can send it out if you need to make a transaction, store your coins elsewhere, or use a different service.
One of the coolest features in Coinbase is that your coins become instantly available.
Bitcoin wallet addresses come in several forms.

Then use the fee slider on the send tab to set a fee when sending bitcoin. The further to the right you move the slider the faster your transaction will confirm and the higher the fee you will pay. Pausing your mouse cursor on the fee slider will display a tooltip with useful information about the fee. Electrum is stuck at synchronizing or will not connect. What can I do to fix this? If either of these is what you are seeing then try these steps:.
To enable debug logging see this question. You can grab the log files from your data dir which is here. Community forums are given here. You can ask for help on the forum , reddit or electrum IRC channel on freenode. Are you talking about importing private keys? There was a change in the user interface with Electrum 3. So make sure you follow the guide above which works with the latest version of electrum. My private key is 52 digits long, generated via bitaddress.
I have the latest version and totally tries to follow those steps, but my problem is, instead of Electrum letting me write down my private key in the window where I should write it, it only lets me write down my Public key.
One or more characters in your private key are incorrect. WIF has a checksum to detect typos and character omissions. Your private key must not be passing the checksum test. Since you are familiar with bitaddress I suggest running that site offline and pasting in your private key on the wallet details tab of it. If there is a problem with the private key bitaddress should point it out to you too.
I am using a new computer now and am trying to transfer the wallet to my new computer. I restored the seed, tried, using a standard wallet, the seed and public key is correct, but it says synchronizing and am not seeing the coins in the new wallet. I was happily using Electrum 2. I upgraded to 3. Instead, a new empty wallet was created. The server that is automatically selected is kirsche.
I suggest you create a thread on one of the community forums because this comments area is not good for a back and forth conversation which is required to diagnose your problem. See here for links to community forums:. Your website have helped me few times. Thanks but I do this to give back to the community.
If you like you can donate to an electrum server. Wat is goin on. Can you use the 2FA feature with your Electrum wallet but use the desktop version of the Electrum wallet,. I am lost! I have followed the steps but my wallet still shows no balance.
Anyone was able to recover their BTC? I bought bitcoins in january I have put them in Electrum wallet wich I recall seeing the bitcoin in that wallet. I changed the computer since then and reinstall Electrum. I have my seed phrase 12 words , my old password and I still know the deposit address used for get the btc wich I know they are unspent still in the wallet.
No balance. Hi, I used my other software wallet on a different device to transfer funds to my electrum wallet using the QR code from the section under the receive tab. The original wallet says that the transaction was confirmed on the blockchain and so I checked my electrum wallet and no funds have appeared even after a week. Nothing under the history tab indicates that a transaction has occurred or any funds were received to my electrum wallet.
I reached out to the tech support of the previous wallet and they told me that everything indicates that the funds were sent and I have had no problems with this other wallet before. This is quite bizarre. Could anybody provide some suggestions on what to do to determine what happened on the Electrum end of things? Hello i have bitcoin on electrum from circa but i dont know how to access them from where they are because i have mispaced them is there any way of accessing them from electrum program from that missing location or what should i do i was only a teenager then and not thinking about how to store them also can you sign into electrum website online cache wallet thats where i thin i saved them with the black background and the logo with writing.
Could I restore my wallet to by bass this block? Maybe on a Tezor? Could I restore my wallet to bypass this? I have the mobile wallet version 4. Unfortunately, the transaction is still left as unpaid even after I add my password. I updated the app but maybe the age of the phone is complicating things? Does the mobile version of the program allows Sweeping a bitaddress paper wallet?
I am having a big issue on Blockchain that I cannot seem to figure out for the life of me! I am definitley new to all of this so I am learning as I go. I did 3 Bitcoin generations the other day that I have not yet recieved payment for but I have already sent payment for each one and the have all been confirmed several times over. The only thing that I see that might have something to do with it is that right next to where it says Imported Bitcoin addresses it also says Verify Message but when I click on it, it comes up blank.
I have no idea what to do… I feel like I have lost all of those funds already.. Someone please help! Someone please help!! Is there a method to show a list of amounts of funds received to address? Or show whole history of address with amounts. I have a Ledger Nano with several wallets created using Ledger Live. But when connecting to Electrum I can only see wallet 0 the first. Is there a way in Electrum to access the other wallets? Thanks, Followed your instructions. And it was spot on!!!
However Ledger Live support Taproot. And hoping for the same that is displayed in Ledger Live. Got a bc1q…. Earliest transaction is When checking BTC. The reason is that output of btc is a pay to public key output not a pay to public key hash output. Thanks for explaining this. Had no idea it was possible. The outcome was exactly as in Electrum. Now you got me curious on the concept of P2PK so of course had to read up on the subject. Is it possible to enter the public key in Bitcoin Core or Electrum?
Or is the private key the only option to see the true output of this address? I did put the link in this post in case others would like to know. Hope this is okay.

Back to the top How does a 2fa wallet work? Back to the top What do the transaction status messages on the history tab mean? Here is what they mean: Unconfirmed Transactions These are transactions that have yet to be incorporated by miners in the blockchain. If you wish to broadcast this transaction right click on it and choose details. Then click on broadcast. Unconfirmed: An unconfirmed transaction that is neither local nor has an unconfirmed parent transaction.
If this is an outgoing transaction you can bump the fee using the increase fee option if you like. Fee in satoshis per byte. Learn more about transaction fees here. These transactions will be incorporated into blocks before your transaction is.
Confirmed Transactions Transactions that have been incorporated in the blockchain have these graphics next to their entry on the history tab: A clock icon means the transaction has confirmed but not enough times to be considered irreversible. For low value transactions you can deliver the goods or services now. For larger transactions you may wish to wait for a green tick. A green tick mark next to the transaction means it has confirmed sufficient number of times and is now irreversible.
Transactions with uncertain status Not verified means that Electrum is not sure whether this transaction is valid. Switch servers or restart Electrum to get a more definite status. Thanks to SomberNight for help with this question. Back to the top What do transaction confirmations mean? Back to the top Receiving bitcoin Where is my bitcoin address?
Back to the top Why does it say "pending" next to my transaction? Back to the top What can I do if I haven't received bitcoins sent to me? There are a few possibilities: Make sure your wallet is synced with the network. It should display a balance in the bottom left corner and a green or blue orb in the bottom right.
If the wallet is synced then look at the history tab to see what transactions were sent to your wallet. The receive tab is not the authoritative source for this. They usually do withdrawals in batches. Check your account at the exchange or other website to make sure the coins were actually sent. If the sender insists that they sent you the coins ask for a transaction ID, which is a long hexadecimal number, and seek help on a community forum.

Back to the top How can I find out how much I will pay in fees when sending bitcoin? Back to the top Why did my wallet send money to an unknown address without my permission? There are 3 possibilities: Change : The way bitcoin works unspent outputs have to be spent in their entirety.
Excess amounts are sent back to a change address in your wallet. To confirm that this is the case right click on the transaction in question on the history tab and choose view transaction. See if the unknown output in question is highlighted in green or yellow. Yellow refers to change addresses while green means receive address. Both change and receiving addresses are a part of your wallet meaning these coins were sent back to your own wallet. You control this money and it is yours.
Bitcoin transactions are irreversible so there is nothing that can be done if your coins are stolen by malware. Back to the top Why am I getting the error message "Not enough funds"? Or why am I not able to send my whole balance when I click max on the send tab? There are two types of transaction fees — miner fees and 2fa fees: Miner Fees : Generally when people speak of transaction fees they mean miner fees that go to the bitcoin miner that mines the block containing your transaction.
Miner fees apply to all wallet types. To view miner fees in Electrum see the article here. You can learn more about these fees by clicking on the little blue shield icon in the bottom right of the main electrum window. Note that the fees are prepayment for a batch of outgoing transactions. Follow on-screen instructions for the rest. To avoid 2fa fees be sure to choose to disable 2fa protection when asked.
Confusion over unit of account : New units like mbtc, bits and so on lead to confusion about how much money you really have in your account and how much you can afford to spend. I strongly recommend switching to BTC as your base unit to avoid misunderstandings like these in future. Unconfirmed vs. Confirmed Coins : If you have received money but that transaction has not yet confirmed Electrum may not allow you to spend that money.
In the case of bitcoin mining rewards you may have to wait until confirmations. You can find out the number of confirmations by right clicking on the transaction in question on the history tab and choosing to view its details. Frozen Addresses: It is possible to freeze addresses so that money sent to them cannot be spent.
Change the filter to change and funded and look again for addresses with coloured backgrounds. If you find any such addresses right click on them and choose unfreeze. Frozen coins : In the same vein as frozen addresses you can also freeze individual unspent outputs which are also known as utxos or coins in the jargon.
Frozen utxos show up with a coloured background on the coins tab. To unfreeze a specific utxo just right click it and choose to unfreeze from the context menu that appears. Back to the top Why am I getting the error message "dust outputs"? Back to the top Why am I getting the message "mempool min fee not met" when sending bitcoin? For more granular control over fees see this article Back to the top Why does it say unpaid on the send tab? Back to the top Install or update What steps should I take to secure my coins before updating Electrum?
Be sure to verify the Electrum download before you continue with the update. The actual update is as simple as installing it over the old version i. Back to the top What is the difference between legacy p2pkh , native segwit p2wpkh or p2wsh and p2sh segwit p2wpkh-p2sh? This type of wallet creates the largest transactions in bytes and costs the most in transaction fees when spending bitcoin. However, it has the widest compatibility for receiving bitcoin from other sites, such as exchanges, and wallet apps.
P2SH segwit p2wpkh-p2sh generates addresses beginning with 3. This type of wallet costs less than legacy but more than native segwit when spending bitcoin. Almost all other wallets and exchanges support sending to p2sh addresses so it is a good compromise option. Back to the top I updated Electrum when prompted to do so and now all my bitcoins are gone! Back to the top My seed is not restoring my wallet! There are two possibilities: Electrum is rejecting your seed as invalid.
For help with that see here. The wallet restoration process completes but the wallet you get is different from the wallet you remember. See here for help with that. Back to the top Why won't Electrum accept my seed when I attempt to restore my wallet from it? Here are some things you can try to solve this issue: Make sure you are using the latest version of Electrum.
The hash of the previous block before it allows the network to properly place the block in chronological order. This is where the term blockchain is derived from — each block is chained to a previous block. The nonce and target are what make mining tick. They are the basis for solving the SHA puzzle that miners need to solve. Please note that all of this data in the block header is compressed into 80 bytes using a notation called little-endian , making the transfer of block headers between nodes a trivially efficient process.
The target stored in the block header is simply a numeric value stored in bits. Recall that the output of SHA is just a number. This numeric value of the hash must be smaller than the target value. Recall the first property of SHA an input into a hash function will always result in the same output. The miner adds a number starting from 0 , called the nonce , to the block header, and hashes that value. This process is repeated continuously until a hash less than the target value is found.
Both the target and the output hash are incredibly large numbers when converted to base 10 remember, over 67 digits long. Instead of trying to demonstrate the comparison of the two here, the following Python function handles the comparison instead:. We then run the same hashing algorithm and comparison on this changed data. If its not below the target, keep repeating. Once a successful hash is found, the latest nonce used to find this solution is saved within the block.
The listed nonce on the Genesis block is 2,,, This means Satoshi Nakomoto iterated through this process over 2 billion times before he found a hash that was acceptable. The nonce value in a block header is stored as a bit number. After 4 billion iterations, the nonce is exhausted, and if a solution is not found, miners are once again stuck. The solution to this is to add a field to the coinbase the transaction contents of a block, stored as the merkle tree called the extraNonce.
The size of this extraNonce is only limited by the size of block itself, and so it can be as large as miners wish as long as the block size is within protocol limits. If all 4 billion possible values of the nonce are exhausted, the extraNonce is added and incremented to the coinbase. A new merkle root and subsequently new block header are calculated, and the nonce is iterated over once again.
This process is repeated until a sufficient hash is found. This requires extra computation in order to propagate the change upwards until a new root of the merkle tree is calculated. A miner who successfully publishes a block the fastest is rewarded brand new Bitcoin, created out of thin air. That reward currently stands at Just how do these Bitcoins come into existence? Each miner simply adds a new output transaction to their block that attributes The network protocol will accept this special transaction as valid upon receiving a newly validated block.
This special transaction is called a generation transaction. There has been at least one case where miners forgot to add the reward to the transaction before mining a block, effectively destroying All this miner has to do is publish the mined block with the original six components to any connected nodes. Once the block is deemed valid, the new node will continue to propagate this block across the network until every node has an up-to-date ledger. As you can see, newly published blocks can easily be verified by any given node.
However, publishing a valid block to the network requires an incredibly large amount of computational power thus, electricity and time. This asymmetry is what allows the network to be secured while simultaneously allowing individuals who wish to conduct economic activity on the network to do so in a relatively seamless manner.
As the first miners began mining, they each monitored the block time. Each Bitcoin block has a set block time of 10 minutes. What this means is that given the current level of computing power network hashrate on the network, nodes will always expect newly validated blocks to be produced every 10 minutes on average.
We can reasonably expect blocks to be produced within 10 minutes because the probability of finding a block, given the network hashrate, is known. Nodes on the network expected four billion of these iterations to be run across all miners on the network every 10 minutes. If, over a large sample size of blocks, blocks start appearing faster than 10 minutes, this is a pretty clear indication that nodes on the network are iterating through four billion hashes much faster than 10 minutes.
This situation prompts every node to adjust the target proportionally based on the increase or decrease in network power to ensure blocks continue to be produced every 10 minutes. In actuality, nodes on the network monitor the block time across blocks, which comes out to exactly two weeks. Every two weeks, the total block time is compared to the expected block time which is minutes. To obtain the new target, simply multiply the existing target by the ratio of the total actual block time over the last two weeks to get the expected block time.
This will adjust the target proportionally to the amount of entering or exiting computing power on the network. The block time and the ability to easily calculate the probability of finding a valid block lets nodes easily monitor and determine the total hashpower on the network and adjust the network.
No matter how much computing power is added to the network or how quickly its added, on average the block time will always remain at 10 minutes. The current total hash rate on the network is You should now be able to understand and explain how proof-of-work actually functions and why it is considered to be an entirely secure algorithm that enables decentralization and consensus!

The client subscribes to its own addresses nit: sha hashes of scriptPubKeys so that it would be notified of new transactions touching them. It also synchronizes the existing history of its addresses. This means the client sacrifices some privacy to the server, as the server can now reasonably guess that all these addresses belong to the same entity.
As above, confirmed transactions are verified via SPV. The server is trusted about unconfirmed transactions. The server can lie by omission. In either case, low-high sanity limits are applied in the client. The main server is also used to broadcast the transactions the client makes.
A list of server peers is also requested by the client, to learn about other servers it can use. Example: slim sugar lizard predict state cute awkward asset inform blood civil sugar. If you have made a transaction that is unconfirmed, you can: Wait for a long time.
Eventually, your transaction will either be confirmed or cancelled. This might take several days. Increase the transaction fee. A window will popup with the unsigned transaction. A CPFP is a new transaction that pays a high fee in order to compensate for the small fee of its parent transaction. It can be done by the recipient of the funds, or by the sender, if the transaction has a change output.
The private keys are decrypted only briefly, when you need to sign a transaction; for this you need to enter your password. In addition, your wallet file may be encrypted on disk. Note that the wallet information will remain unencrypted in the memory of your computer for the duration of your session. If a wallet is encrypted, then its password will be required in order to open it. Note that the password will not be kept in memory; Electrum does not need it in order to save the wallet on disk, because it uses asymmetric encryption ECIES.
You will need to back up this wallet, because it cannot be recovered from a seed. Amounts are in the current unit set in the client. The total is shown in the GUI. Can Electrum create and sign raw transactions? For example, if you wanted to generate 50 addresses, you could do this: [ wallet. Some Electrum upgrades will modify the format of your wallet files. The following issues should be considered when upgrading Electrum 1. Please allow it time to complete, and expect it to take a little longer than usual for Electrum to be ready.
The contents of your wallet file will be replaced with an Electrum 2 wallet. This means Electrum 1. This is expected behavior. Restart Electrum 2 after the upgrade is complete and your addresses will be available. Offline copies of Electrum will not show the addresses at all because it cannot synchronize with the network.
You can force an offline generation of a few addresses by typing the following into the Console: wallet. If it is self-signed, it will only accept that cert until it expires for that server TOFU. If it is CA signed, it will forever only accept CA-signed certs for that server. For your own server, both CA-signed and self-signed certs have their advantages.
With self-signed certs, as the client uses TOFU, there is a possibility of man-in-the-middle during the first connection. With CA-signed certs, you need to trust the Certificate Authorities. Electrum only supports Bitcoin.
