Kaspa, a cryptocurrency similar to Bitcoin, uses a method called unspent transaction outputs or UTXOs. Unlike other blockchains like Ethereum and Tron, which use accounts, Kaspa’s system is more secure and transparent.
In a UTXO-based blockchain, transactions are made up of inputs and outputs, rather than accounts or wallets. This method, first introduced in Bitcoin’s whitepaper, records coins as a list of unspent outputs.
When making a transaction on Kaspa, you use existing UTXOs and create new ones. For example, if you need to pay for something that costs 200 KAS and you have a UTXO worth 500 KAS, the full amount is sent to the recipient. The protocol then sends the remaining 300 KAS back to your address as a new, smaller UTXO.
Currently, the transaction fee on Kaspa is 0.0001 Kas per UTXO. For more information on Kaspa, you can visit their website or join their Discord, Telegram, Twitter, Reddit, Github, or Explorer.
