What is ADA: Understanding the Cardano Blockchain and Its Native Cryptocurrency

Cardano's Positioning and Significance

In 2017, Charles Hoskinson launched Cardano (ADA), aiming to address scalability, interoperability, and sustainability issues in blockchain technology.

As a third-generation blockchain platform, Cardano plays a crucial role in DeFi, smart contracts, and digital identity sectors.

As of 2025, Cardano has become one of the top cryptocurrencies by market capitalization, boasting millions of users and an active developer community.

This article will delve into its technical architecture, market performance, and future potential.

Origin and Development History

Birth Background

Cardano was created by Charles Hoskinson in 2017, aiming to solve scalability and sustainability issues in existing blockchain networks.

It was born during the blockchain technology boom, with the goal of providing a more efficient and sustainable blockchain platform to change the status quo.

Cardano's launch brought new possibilities for developers and enterprises seeking a scalable and sustainable blockchain solution.

Important Milestones

• 2017: Mainnet launch, implementing proof-of-stake consensus mechanism.
• 2020: Shelley upgrade introduced decentralized block production.
• 2021: Alonzo upgrade enabled smart contract functionality, pushing the price to break $3.
• 2022: Vasil hard fork improved scalability and smart contract capability.

With support from the Cardano Foundation and IOHK, Cardano continues to optimize its technology, security, and real-world applications.

How Does Cardano Work?

No Central Control

Cardano runs on a decentralized network of computers (nodes) spread globally, free from control by banks or governments. These nodes collaborate to validate transactions, ensuring system transparency and attack resistance, giving users greater autonomy and improving network resilience.

Blockchain Core

Cardano's blockchain is a public, immutable digital ledger that records every transaction. Transactions are grouped into blocks and linked through cryptographic hashes to form a secure chain. Anyone can view the records, establishing trust without intermediaries. Cardano's unique Ouroboros proof-of-stake protocol further enhances performance and energy efficiency.

Ensuring Fairness

Cardano uses a Proof-of-Stake (PoS) consensus mechanism to validate transactions and prevent fraudulent behaviors like double-spending. Stake pool operators maintain network security by running nodes and staking ADA, and receive ADA rewards in return. Its innovations include energy efficiency and high throughput.

Secure Transactions

Cardano uses public-private key cryptography to protect transactions:

• Private keys (like secret passwords) are used to sign transactions
• Public keys (like account numbers) are used to verify ownership

This mechanism ensures fund security, keeping transactions pseudonymous. Additional security features include multi-signature wallets and advanced cryptographic techniques.

Cardano's Market Performance

Circulation Overview

As of November 14, 2025, Cardano's circulating supply is 36,595,373,755.20915 ADA, with a total supply of 45,000,000,000 ADA. This indicates a fixed supply model.

Price Fluctuations

Cardano reached its all-time high of $3.09 on September 2, 2021, driven by overall market bullishness and increased adoption.

Its lowest price was $0.01925275, occurring on March 13, 2020, likely due to the global market crash associated with the COVID-19 pandemic.

These fluctuations reflect market sentiment, adoption trends, and external factors.
