A Coinbase transaction is a special type of transaction that occurs during the creation of new blocks on a blockchain, like Bitcoin. It is unique because it is the first transaction in a block and rewards miners for their work in processing transactions and securing the network.This transaction allows miners to receive new coins as payment for their efforts. For instance, when a miner solves a block, they are granted a specific amount of newly generated coins, which is predetermined by the network. The coinbase transaction also includes any transaction fees from regular transactions included in the block, adding to the miner’s reward.Unlike standard transactions, a coinbase transaction does not have input references to previous transactions. Instead, it generates coins out of thin air, which is why it is considered the only way new coins are introduced into the system. This mechanism ensures that the total supply of coins is capped, contributing to the asset’s scarcity over time.
