Aptos is a [Layer 1](https://coinmarketcap.com/alexandria/glossary/layer-1-blockchain) [Proof-of-Stake](https://coinmarketcap.com/alexandria/glossary/proof-of-stake-pos) (PoS) blockchain that employs a novel [smart contract](https://coinmarketcap.com/alexandria/glossary/smart-contract) programming language called Move, a Rust-based programming language that was independently developed by Meta (formerly Facebook)’s Diem blockchain engineers.

Aptos’s vision is a blockchain that brings mainstream adoption to [web3](https://coinmarketcap.com/alexandria/article/what-is-web-3-0) and empowers an ecosystem of [DApps](https://coinmarketcap.com/alexandria/glossary/decentralized-applications-dapps) to solve real-world user problems.

The PoS blockchain can achieve a theoretical transaction [throughput](https://coinmarketcap.com/alexandria/glossary/throughput) of over 150,000 [transactions per second](https://coinmarketcap.com/alexandria/glossary/transactions-per-second) (tps) through parallel execution.
