coinbase

Coinbase can refer to two related but distinct concepts:

1. **In cryptocurrency block creation:** The *coinbase* is a special type of transaction in a block - the first transaction - that is created by a miner or validator. It has no inputs and generates new cryptocurrency as a block reward, along with any transaction fees.

2. **As a company name:** **Coinbase** is a U.S.-based cryptocurrency exchange platform that allows users to buy, sell, and store various digital assets.
