Aptos is a Layer 1 blockchain built by former Meta (Facebook) engineers who worked on the Diem blockchain project. It uses the Move programming language for smart contracts, designed for safety and resource scarcity. APT is used for transaction fees, staking, and governance. The network targets high throughput with parallel transaction execution and hosts institutional tokenized assets.
Aptos uses the AptosBFT consensus algorithm (based on HotStuff, a BFT variant) providing fast finality in approximately 1 second. Its key technical innovation is Block-STM (Software Transactional Memory), which executes transactions in parallel by speculatively running them and detecting conflicts, then re-running only conflicting ones. Smart contracts use the Move language, which treats digital assets as resources that cannot be duplicated or unexpectedly disappear. In 2025, governance voted to cap APT supply at 2.1 billion tokens, with staking rewards to decrease and transaction fees used to buy and burn APT toward the target.
Aptos was designed to be the production-grade blockchain that Diem (originally Facebook's Libra) aspired to be — serving billions of users with safety guarantees that traditional languages like Solidity cannot provide. The Move language's resource model prevents common smart contract vulnerabilities like reentrancy and unauthorized duplication of assets. It aims to combine institutional-grade reliability with consumer-scale throughput.
Block-STM parallel transaction execution combined with the Move resource-safe programming language, built by the team that designed Meta's Diem blockchain and targeting institutional-grade reliability at consumer scale.
