Jun 12, 2025
Aptos is a new Layer-1 blockchain that aims to deliver fast, secure, and scalable decentralised applications (dApps). Built by former Meta (Facebook) engineers, it introduces innovative features that make it stand out in the blockchain ecosystem. This article explains what Aptos is, how it works, and why it’s gaining attention.
What Is Aptos?
Aptos is a Layer-1 blockchain protocol designed to support the next generation of Web3 applications. It was developed by Aptos Labs, a team of engineers who previously worked on Meta’s (formerly Facebook) Diem blockchain project.
The Aptos blockchain is built using the Move programming language, which prioritises security and flexibility.
A Layer-1 blockchain similar to Ethereum or Solana
Developed by former Meta engineers
Uses the Move language for smart contracts
Focuses on speed, security, and scalability
Aims to power the future of Web3
How Does Aptos Work?
Aptos uses a unique parallel execution engine called Block-STM, which allows multiple transactions to be processed at the same time. This helps the network maintain high throughput without compromising security.
In addition, Aptos separates consensus from execution, allowing for faster finality and improved efficiency.
