What is ACA: Understanding the Affordable Care Act and Its Impact on Healthcare

Acala's Positioning and Significance

In 2022, the Acala team launched Acala (ACA), aiming to address challenges in decentralized finance and interoperability within the Polkadot ecosystem.

As the first DeFi hub and liquidity center on Polkadot, Acala plays a crucial role in the DeFi and cross-chain interoperability domains.

As of 2025, Acala has become a core asset in the Polkadot ecosystem, boasting 183,340 holders and an active developer community. This article will delve into its technical architecture, market performance, and future potential.

Origin and Development History

Birth Background

Acala was created by the Acala team in 2022 to solve the lack of comprehensive DeFi infrastructure in the Polkadot ecosystem. It emerged during the expansion of the Polkadot ecosystem and the growing demand for cross-chain DeFi solutions, aiming to provide a scalable, Ethereum-compatible platform optimized for DeFi. Acala's launch brought new possibilities for developers and users in the Polkadot ecosystem.

Important Milestones

• 2022: Mainnet launch, achieving Ethereum compatibility and native DeFi applications.
• 2022: Introduction of Acala Dollar (aUSD), a decentralized stablecoin for the Polkadot ecosystem.
• 2023: Implementation of Acala EVM+, enhancing smart contract capabilities.
• 2024: Ecosystem expansion, with the number of DeFi protocols exceeding 100.

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

How Does Acala Work?

Decentralized Control

Acala operates on a decentralized network of computers (nodes) worldwide, 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 Core

Acala'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. Acala's unique layer-1 smart contract platform further enhances performance and interoperability within the Polkadot ecosystem.

Ensuring Fairness

Acala employs a Nominated Proof-of-Stake (NPoS) consensus mechanism to validate transactions and prevent fraudulent activities like double-spending. Validators and nominators maintain network security by staking ACA tokens and running nodes, receiving ACA rewards in return. Its innovations include high scalability and cross-chain interoperability within the Polkadot network.

Secure Transactions

Acala 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, with transactions remaining pseudonymous. Additional security features include cross-chain message passing and multi-signature capabilities.
