While not well known, the popular Crypto Exchange Coinbase was actually named after the Coinbase transaction. This is a special transaction in each new block that details where the newly minted bitcoins are to be sent.

When Bitcoin Miners successfully mine a new block, they’re rewarded with the block subsidy. These newly minted bitcoins are the first transaction in each block and have no “input” to them as shown in this example Coinbase transaction from block 796,992.
Every UTXO, if traced back through enough transactions, can be tracked back to its original Coinbase transaction. Currently the block subsidy is 6.25 BTC, however after the next Bitcoin Halving it will be reduced to 3.125 BTC. The reason this Coinbase transaction has a UTXO of 6.63215949 BTC is because 6.25 BTC is for the block subsidy and the rest (0.38215949 BTC) is from all the fees in each transaction inside the block.
