What Is Change In A Utxo Based Crypto

Why Your Bitcoin Wallet Address Changes Every Time?

UTXO cryptocurrencies work in a similar way to physical cash.

For Example: lets say you are paying for a meal, and it costs $20. You reach into your pocket and pull out a $50 bill that you hand to the waiter, who returns with $30 in change, which you then put in your wallet.

Using Bitcoin in this example. Any Bitcoin youve received in your Bitcoin wallet is like bills waiting to be spent. Lets say now you are paying for your meal with Bitcoin and it costs 20 BTC .

You have 50 BTC inside of your wallet. So when you pay your 20 BTC for your meal, you receive 30 BTC in change as expected. But this change is sent to another address controlled by your Bitcoin wallet, called a change address.

Why Does Your Bitcoin Address Keep Changing

As we said if you are using Bitcoin address as an account number then you are doing it wrong. You need to understand that Bitcoin transactions are traceable. Meaning they are public and are permanently stored in the blockchain.

If you use the same Bitcoin address to receive funds then it will get easy for anyone to track your payment history. This is why it is advised that whenever you receive a payment you need to use a new address. This way it becomes harder for one to decide that the address being used is yours by verifying it on the block explorer.

Bitcoin wallet has a feature of changing address to ensure that you are being provided with an unique address every time you make a transaction. Not all wallet types, but specifically HD wallets. This is done to protect your privacy and its a basic security protocol build into Bitcoin network.

Okay, but what about my previously used Bitcoin address?

Receiving Change To Same Address Degrades Privacy

Well you can send the change output to the same address. While sending to same address simplifies accounting it reduces users privacy. As we said earlier in this article change addresses play a key role in improving privacy.

Two-factor authentication is a way to add additional security to your wallet. The first ‘factor’ is your password for your wallet. The second ‘factor’ is a verification code retrieved via text message or from an app on a mobile device. 2FA is conceptually similar to a security token device that banks in some countries require for online banking. It likely requires relying on the availability of a third party to provide the service.

The Debit Card From Hell

Imagine paying for groceries with a debit card. The checker totals the amount due and you swipe your card as usual. However, you notice the payment terminal is asking for all of the money in your account.

The checker smiles, explaining that this is part of your bankâs new rewards program. You have three options: send the change back to your current account send the change to a newly-created bank account or say nothing and send the change to the payment terminal company.

Counterintuitive? Confusing? Alarming? Many Bitcoin users are surprised to find eerie similarities between this diabolical debit card and the way transactions seem to work.

Thinking about Bitcoin in terms of past experiences with online banking and debit cards can lead to problems. Fortunately, an older payment method offers better insights into how Bitcoin works.

Change Addresses And Privacy

By design, every Bitcoin transaction remains permanently viewable in a global public log called the âblock chain.â Privacy depends on the strict separation between addresses and personal identities, a model referred to as pseudonymity.

Any observer capable of linking Bitcoin addresses to personal identities can begin to draw conclusions about money transfers between people. Users make this job more difficult by sending change to newly-created addresses.

To see why, imagine a transaction that sends funds from Address A to Address B. If change is returned to Address A, the block chain reveals that the person controlling Address A paid the person controlling Address B. The same reasoning holds if two or more addresses are involved. Any transaction involving Address A as a sender reveals the receiving address unambiguously.

Change Address is Sender.

Should the identity of the person controlling either receiving or payment addresses become known, the identities of the other parties could become known as well.

Change Address is not Sender.

An observer trying to link personal identities to addresses must gather more secondary information and expend more resources when all parties send change to newly-created addresses.

Coordinating multiple addresses is a complicated task. Wallet software frees the user from the need to do this manually.

What’s The Bitcoin Network Fee

Many Bitcoin wallets allow you to customize the Bitcoin network fees you pay when you send 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 , 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.

Change Address And Output Explained

How to Get Your Coinbase Bitcoin Wallet Address

In Bitcoin change output is nothing but the remainder amount or the extra amount of satoshi which the spender used in a transaction but is returned back to the spender itself. It is returned back because they dont wish to pay anything more than the specified amount. The address to which the change output is returned back is called change address. This change address is usually a new Bitcoin address which the client generates for the sender to receive back the difference amount.

So instead of getting the difference back why not pay the exact amount of Bitcoins in first place?

To understand the concept of change address or change output lets first understand the fundamentals of Bitcoin transaction.

Whats A Bitcoin Receiving Address

A receiving address is similar to your bank account number. Each bitcoin wallet has a unique bitcoin receiving address. You can share this bitcoin address with others to let them know how to send coins to your wallet.

A BTC address is alphanumeric and always starts with a 1 or a 3. This is an example of a receiving address: 3FZbgi29cpjq2GjdwV8eyHuJJnkLtktZc5. A common question is how to get a BTC address. Each wallet automatically generates a bitcoin address. If youve just created a new wallet, then you have a unique bitcoin address right away. When you enter this address on our order form, well know where to send the coins to.

A new bitcoin address is not only generated once youve created a new wallet, but after each transaction as well. And for a good reason: when your address regularly changes, your privacy on the network is better protected.

Would you like to use your old bitcoin address again? No problem! Each address on which youve previously received bitcoin, can be used again. It doesnt matter if someone sends coins to your most recent address or to your oldest address- the bitcoins will arrive in the same wallet. In most wallets all generated addresses can be found in the transaction history.

Learn How To Securely Send Bitcoin

Sending bitcoin is as easy as choosing the amount to send and deciding where it goes.

The exact procedure for doing so will depend on the type of Bitcoin wallet you’re using, but the main thing you need to know is the’address’ of the recipient. A Bitcoin address is an alphanumeric string that looks something like this:

3J98t1WpEZ73CNmQviecrnyiWrnqRhWNLy

One way to send bitcoin, then, is to simply copy the recipient’s address to your clipboard, then paste it in the send field of the Bitcoin wallet app you’re using.

Bitcoin addresses can also be displayed in QR code format. If you’re sending bitcoin from a mobile wallet like the Bitcoin.com Wallet, you can use your phone’s camera to scan the QR code of the address you want to send to. This will automatically fill in the address.

As for the amount to send, most wallets allow you to toggle between showing the send amount as bitcoin or showing it in your local currency.

IMPORTANT: Bitcoin transactions are irreversible, so if you send to the wrong address, you’ll most likely never see that bitcoin again.

Private And Public Keys

A bitcoin wallet contains a collection of key pairs, each consisting of a private key and a public key. The private key is a number, usually picked at random. From the private key, we use elliptic curve multiplication, a one-way cryptographic function, to generate a public key . From the public key , we use a one-way cryptographic hash function to generate a bitcoin address . In this section, we will start with generating the private key, look at the elliptic curve math that is used to turn that into a public key, and finally, generate a bitcoin address from the public key. The relationship between private key, public key, and bitcoin address is shown in Figure 4-1.

Are An Address And A Wallet The Same Thing

Bitcoin Core Wallet 0.19.0.1 Is Released With A New ...

A wallet and an address are not the same thing. An address is a public key to which transactions can be sent. This concept is present in the Bitcoin protocol itself. A wallet is a collection of private keys that corresponds to addresses.

Your private key is a randomly generated string , allowing coins to be spent. A private key is always mathematically related to the identifier, but is impossible to reverse engineer thanks to a strong encryption code base. If you dont backup your private key and you lose it, you can no longer access your wallet to spend funds.

There is also a public key. This causes some confusion, as some people assume that a address and the public key are the same. That is not the case, but they are mathematically related. A Bitcoin wallet identifier is a hashed version of your public key. The public key is used to ensure you are the owner of an address that can receive funds. The public key is also mathematically derived from your private key, but using reverse mathematics to derive the private key would take the worlds most powerful supercomputer many trillions of years to crack.

Besides these key pairs and a Bitcoin wallet address, your software also stores a separate log of all of your incoming and outgoing transactions. Every transaction linked to your identifier will be stored by the wallet to give users an overview of their spending and receiving habits.

    How Do I Set The Btc Network Fee In My Bitcoin Wallet

    This, again, depends on the wallet. In fact, many web wallets don’t give you any control over the network fee whatsoever. Instead, they have a predetermined fee . In other words, they profit when their customers withdraw bitcoin. This is a common revenue-generation strategy for cryptocurrency exchanges.

    Most non-custodial wallets, however, allow you to customize the fee you attach to your Bitcoin transactions. The Bitcoin.comWallet, for example, has three convenient fee settings, as well as the option to set custom fees. The default speed is set to have your transaction confirmed most likely within the next three blocks . If you change it to ââ¬ÅFastest,ââ¬ï¿½ youââ¬â¢ll pay a higher fee and likely have your transaction confirmed in the next two blocks . Changing it to ââ¬ÅEcoââ¬ï¿½ will save you some money, but still result in your transaction most likely getting confirmed within the next six blocks, so generally less than 60 minutes. For advanced users, you also have the option of setting a custom fee. Youââ¬â¢ll want to use a tool like Bitcoinfees to ensure youââ¬â¢re choosing an appropriate fee given the current state of network congestion.

    What Is Bitcoin Change Address & Change Output In Bitcoin

    Bitcoins change output is merely the extra amount of Satoshis that spender doesnt wish to spend and thus are returned to the spender.

    And the address on which this Change Output is returned back to the spender is called the Bitcoin change address.

    This needs to be done because if you want to pay someone with a certain amount of bitcoins, then the total amount of bitcoins on that particular address needs to be spent in its entirety.

    And most of the times the value of bitcoin available on a Bitcoin address is higher than what the sender wishes to pay.

    In this case Bitcoin client generates new Bitcoin change addresses in the wallet itself to send the difference back to this address. This is also known as change or change output.

    Is it still confusing?

    Well, let look at this day to day example:

    Say you went to the nearby grocery store to buy groceries.

    You have selected the groceries, and your total bill is coming as $68. You get to your wallet and find that you only have a $100 bill which you give it to the cashier. The cashier returns 32 dollars to you.

    Now in the fiat realm, only central banks have the authority to print notes/bills of different denominations, and in this case, your fiat transaction details look like this:

    Input

    • $100 bill
    • $32 bill to you

    Thats precisely how Bitcoin works.

    For example, take this case of Bitcoin transaction: 0a1c0b1ec0ac55a45b1555202daf2e08419648096f5bcc4267898d420dffef87
