What is Cardano? A 2026 Guide for Australians

Cardano is an open, public blockchain network that launched in September 2017 and runs on a proof-of-stake consensus design called Ouroboros, published through peer-reviewed academic research. ADA is the network's native coin: it pays transaction fees and can be delegated to a stake pool without leaving your wallet. This guide covers the difference between the Cardano network and ADA, how staking and delegation work, what the chain is used for, when smart contracts arrived with the Alonzo hard fork in September 2021, how it compares with Bitcoin and Ethereum, and the Australian angle: AUSTRAC-registered platforms for AUD purchases, ATO capital gains tax basics, staking-reward record keeping, custody choices and the main risks. Education only — not financial advice. Publisher: Eagle BTM Pty Ltd ACN 659 281 820 (AUSTRAC DCE / VASP).
