Utilizing UTXOs and developing wallets

In this section, we will explore the implementation of UTXO and wallet functionalities. UTXO tracking and wallet management play pivotal roles in blockchain systems, ensuring transaction outputs’ integrity and secure asset storage and transfer.

Let us first look at the UTXOSet structure.

Implementing UTXOSet

The UTXOSet structure helps manage UTXOs within a blockchain. It facilitates functionalities such as finding spendable outputs, reindexing outputs, updating outputs after block confirmation, and counting transactions within the blockchain.

You will find the following code in the file:

pub struct UTXOSet {
    blockchain: Blockchain,
}
impl UTXOSet {
  pub fn new(blockchain: Blockchain) -> UTXOSet {
        UTXOSet { blockchain }
    }
    pub fn get_blockchain(&self) -> &Blockchain {
  ...
