Cardano (ADA) is a blockchain platform founded in 2015 by Charles Hoskinson, one of the co-founders of Ethereum. It was developed by Input Output Hong Kong (IOHK), with a strong focus on academic research, peer-reviewed development, and scalability. Cardano aims to provide a secure and sustainable blockchain for smart contracts, decentralized applications (dApps), and financial services.

Key Milestones in Cardano's History

1. 2015 – Foundation & Development

Charles Hoskinson and Jeremy Wood establish IOHK to develop Cardano.

The project focuses on scientific research and a layered blockchain architecture.

2. 2017 – Launch of Byron (Phase 1)

Cardano mainnet goes live.

ADA token is launched and traded on exchanges.

Uses Ouroboros, a proof-of-stake (PoS) consensus mechanism.

3. 2020 – Shelley Upgrade (Phase 2)

Introduces full decentralization with staking and delegation.

Community members can operate stake pools.

4. 2021 – Goguen Upgrade (Phase 3)

Introduces smart contracts via the Alonzo hard fork.

Developers can now create decentralized applications (dApps) on Cardano.

5. 2022 – Basho Upgrade (Phase 4)

Focuses on scalability and interoperability.

Introduces sidechains and enhances network efficiency.

6. 2023-2024 – Voltaire Era (Phase 5, ongoing)

Aims for full decentralization with governance mechanisms.

Community-driven development and decision-making.

Key Features of Cardano

Proof-of-Stake (PoS): More energy-efficient than Bitcoin’s Proof-of-Work (PoW).

Peer-Reviewed Research: Built on academic principles.

Layered Architecture: Separates settlement and computation layers for efficiency.

Scalability & Security: Designed for long-term sustainability.

Today, Cardano is considered one of the top blockchain projects, competing with Ethereum in the smart contract space. Would you like details on its future roadmap or specific aspects?
