UTXOs And Bitcoin’s Accounting Model

what are utxos in a bitcoin blockchain

UTXO stands for the unspent output from bitcoin transactions. Each bitcoin transaction begins with coins used to balance the ledger. UTXOs are processed continuously and are responsible for beginning and ending each transaction.

But a record of the spent coins still exists on the ledger. Bitcoin transactions are similar to cashier checks. You cannot exchange them for custom amounts and must spend the entire amount stored in that data byte. But bitcoin is also unique in that transactions can be conducted using fractions of the cryptocurrency. Spending in bitcoin does not take place using a single data byte.

Instead, multiple fractions of bitcoin are retrieved by the algorithm to fulfill a spending request. For example, a purchase worth 1 BTC may retrieve 0. Change from each of these fractions is sent to the UTXO database. A UTXO database stores change from bitcoin transactions. Initially, it is set to empty. As transactions multiply, however, the database is populated with change records from various transactions. This is because it may cost more to transact than the actual cost of the product being purchased with bitcoin.

There is another problem with increasing UTXO. The change in equipment cost required to processing UTXOs has not kept pace with its increase. As an example, the cost of mining rigs for fully validating nodes has not kept pace.

This first course of the Blockchain specialization provides a broad overview of the essential concepts of blockchain technology — by initially exploring the Bitcoin protocol followed by the Ethereum protocol — to lay the foundation necessary for developing applications and programming. You will be equipped with the knowledge needed to create nodes on your personal Ethereum blockchain, create accounts, unlock accounts, mine, transact, transfer Ethers, and check balances. You will learn about the decentralized peer-to-peer network, an immutable distributed ledger and the trust model that defines a blockchain. This course enables you to explain basic components of a blockchain transaction, block, block header, and the chain its operations verification, validation, and consensus model underlying algorithms, and essentials of trust hard fork and soft fork. Content includes the hashing and cryptography foundations indispensable to blockchain programming, which is the focus of two subsequent specialization courses, Smart Contracts and Decentralized Applications Dapps.
