When you open the SafePal wallet and look at your Bitcoin balance, you see a number. For this example, let's set the balance at 100 BTC. Though the balance is an intact number, your Bitcoins are actually comprised of multiple UTXOs. You may have two UTXOs worth 50 each, four UTXOs worth 25 bitcoin each, or a set of UTXOs valuing 32, 10, 21, and 37 bitcoin. The amounts for each UTXO don’t matter, but they must add up to your total balance. Let's assume that you want to buy a house that costs 35 bitcoin, and your wallet only contains UTXOs equaling 15, 17, 28, and 40 bitcoin each, then you will have to pay the 40 bitcoin UTXO because you don’t have one UTXO valued at precisely 35 bitcoin. In this case, the network mints two new UTXOs: one valued at 35 bitcoin, one worth 5 bitcoin. The car dealership receives the 35 bitcoin UTXO while you receive the 5 bitcoin UTXO as change. You may also spend the 17 and 28 bitcoin UTXOs and receive 10 bitcoin as your change. A transaction may use any combination of UTXOs; however, you don’t have control over which ones. Just as you can split a UTXO into separate instances, you can also combine them in larger transactions, creating fewer of them on the network.
As a seasoned expert in blockchain technology and cryptocurrency, my deep understanding of the subject matter positions me to provide insightful and comprehensive information on the concepts mentioned in the article about SafePal wallet and Bitcoin UTXOs.
The article delves into the intricacies of Bitcoin balances and the underlying concept of Unspent Transaction Outputs (UTXOs). Here's a breakdown of the key concepts:
SafePal Wallet:
The article assumes the use of the SafePal wallet, a cryptocurrency wallet known for its security features. While not explicitly detailed in the text, it is implied that the wallet is used for managing Bitcoin transactions.
Bitcoin Balance and UTXOs:
When users check their Bitcoin balance in the SafePal wallet, they encounter a single numerical representation (e.g., 100 BTC). However, this balance comprises multiple Unspent Transaction Outputs (UTXOs).
UTXOs are individual units of Bitcoin that have not been spent and are used to determine the overall balance. The article gives examples, such as having two UTXOs worth 50 BTC each, four UTXOs worth 25 BTC each, or a combination of UTXOs totaling the displayed balance.
UTXO Composition:
The composition of UTXOs is flexible, with different UTXOs having varying values. The sum of all UTXO values equals the total balance displayed in the wallet.
Buying a House Example:
The article provides a practical scenario where a user wants to buy a house costing 35 BTC. However, their wallet only contains UTXOs of 15, 17, 28, and 40 BTC each. To make the purchase, the user must use the 40 BTC UTXO, as there isn't a single UTXO valued at exactly 35 BTC.
UTXO Splitting and Minting:
In the absence of a UTXO matching the exact amount needed, the network mints new UTXOs. In the house-buying example, the network creates two new UTXOs: one valued at 35 BTC (for the house purchase) and one worth 5 BTC (as change for the user).
This process illustrates how the blockchain network handles transactions by splitting and minting UTXOs as necessary.
Transaction Flexibility:
The article emphasizes that a transaction can use any combination of UTXOs, but users do not have control over which ones are utilized. This lack of control is a fundamental characteristic of Bitcoin transactions.
Combining UTXOs:
Highlighting the flexibility of UTXOs, the article mentions that just as UTXOs can be split into separate instances, they can also be combined in larger transactions. This results in fewer UTXOs on the network.
In conclusion, the article provides a nuanced understanding of how Bitcoin balances, UTXOs, and transactions work within the context of the SafePal wallet. The examples and scenarios presented underscore the intricacies of managing and utilizing UTXOs in the cryptocurrency ecosystem.
Each UTXO is distinct and can hold any amount of bitcoin. They are the pieces of bitcoin you haven't spent yet, and you use them to make new payments. As its name suggests, a UTXO is an output of a bitcoin transaction
bitcoin transaction
A Bitcoin transaction is a transfer of bitcoin from one address to another. The valid transaction must be signed by the sender. Bitcoin does not have accounts. Instead, pieces of Bitcoin of arbitrary size are all associated with an address, which is controlled by the owner of that bitcoin.
Next, the user provides their digital signature to confirm ownership over the inputs, which finally result in outputs. The UTXOs consumed are now considered "spent," and can no longer be used. Meanwhile, the outputs from the transaction become new UTXOs – which can be spent in a new transaction later.
If you spend $12 on lunch using a $20 bill, you'd have a $8 bill leftover. In this example, the leftover $8 would be an unspent transaction output. It would go back in your wallet ready to be used to buy something else. This is exactly how bitcoin UTXOs work.
Of course, each transaction is conditional on the UTXOs being used as input to be both valid and unspent. Other cryptocurrencies using the UTXO model are Cardano, Litecoin and Bitcoin Cash. In short, UTXOs represent all Bitcoins in circulation as well as their respective owners.
Accordingly, the UTXO model is a way of organizing a blockchain's ledger such that no funds are spent twice, avoiding the double spending problem. Once a UTXO is spent, one (or more) new UTXO are created as a result of that transaction. The new UTXO are created and sent to the appropriate wallet(s).
If it hasn't been used in any subsequent transactions, it's considered unspent. Conversely, once an output has been used in a transaction, it becomes spent. UTXOs are the unspent outputs of previous transactions. They represent the cryptocurrency that a user possesses and can use in future transactions.
Less user-friendly: Transactions can be more complex with multiple UTXOs involved, compared to the simpler account-based system.
Limited programmability: Standard UTXOs don't support complex smart contracts, although newer variations like Nervos' "cell model" aim to address this.
The conceptual difference is that the account model updates user balances globally.The UTXO model only records transaction receipts. In the UTXO model, account balances are calculated on the client-side by adding up the available unspent transaction outputs (UTXOs).
The EUTXO model offers unique advantages over other accounting models. The success or failure of transaction validation depends only on the transaction itself and its inputs, and not on anything else on the blockchain.
Ethereum uses the account-based model, while Bitcoin uses UTXOs (short for Unspent Transaction Outputs ) to keep track of user state/balances. The UTXO model differs pretty drastically from the account model.
Today's price of UTXO is $0.00138988, with a 24-hour trading volume of $3.01K. UTXO is -3.52% in the last 24 hours, with a circulating supply of -- UTXO coins and a maximum supply of -- UTXO coins. UTXO ranks -- by market cap.
If there are too many UXTOs, the node which broadcasts the transaction rejects it, so you need to clean up your UXTOs by sending money to yourself. If you have thousands of low UXTOs (1000 - Higher) you will need to do it again with a very tiny amount a few times and then a larger one a few times.
