View ChartCardano (ADA) is a decentralized proof-of-stake (PoS) blockchain platform intended for use by developers around the world. Similar to Ethereum, Cardano's PoS consensus mechanism rewards cryptocurrency for work done in reviewing and expanding the historical blockchain record.
In January 2025, the Cardano blockchain and project transitioned to its final phase, becoming a system for decentralized applications (dApps) with multiple use cases, which will be governed by a community. The blockchain's cryptocurrency token is named ADA after Augusta Ada King, Countess of Lovelace—an English aristocrat who is widely considered to be the world's first computer programmer. ADA can be purchased on most major cryptocurrency wallets and exchanges.
While Bitcoin was developed as a peer-to-peer payment system, Cardano is focused on fostering a general blockchain ecosystem that allows developers to create other tokens, decentralized applications (dApps), and any other uses that a scalable blockchain network can host.
Cardano's PoS consensus mechanism uses staking to validate transactions and reward validators with cryptocurrency, whereas Bitcoin's PoW relies on mining. Cardano's PoS uses drastically less energy than Bitcoin's PoW, as it removes the need for computers to consume large amounts of electricity powering complex mining processes.
Cardano's PoS consensus mechanism also makes its validation process more accessible to the average user than Bitcoin's PoW. Cardano staking can be done simply by installing compatible wallet software on computers or devices. While Bitcoin mining can also be done this way, it is not very efficient, even when done through a pool, which is the least commitment-intensive mining option.
