What is ADA: Understanding the Americans with Disabilities Act and Its Impact on Society

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 decentralized applications.

As of 2025, Cardano has become one of the top cryptocurrencies by market capitalization, with a large and 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 interoperability issues in existing blockchain platforms.

It was born during the blockchain technology boom, with the goal of providing a more sustainable, scalable, and interoperable blockchain solution.

Cardano's launch brought new possibilities for developers and enterprises looking for a robust blockchain platform.

Important Milestones

• 2017: Mainnet launched, implementing proof-of-stake consensus mechanism.
• 2020: Shelley upgrade introduced decentralized block production.
• 2021: Smart contract functionality added through the Alonzo hard fork.
• 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 across the globe, free from control by banks or governments. These nodes collaborate to validate transactions, ensuring system transparency and attack resistance, empowering users with greater autonomy and enhancing network resilience.

Blockchain CoreCardano'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 activities like double-spending. Stake pool operators maintain network security by running nodes and staking ADA, and receive rewards in return. Its innovations include energy efficiency and higher throughput compared to traditional PoW systems.

Secure Transactions

Cardano uses public-private key cryptography to secure 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, while transactions remain pseudonymous. Additional security features include multi-signature transactions and hardware wallet support.

Cardano's Market Performance

Circulation Overview
