Aptos is a scalable layer-1 blockchain built with Move language. It offers new and novel innovations in consensus, smart contract design, system security, performance, and decentralization. The combination of these technologies will provide a fundamental building block to bring web3 to the masses:

First, the Aptos blockchain natively integrates and internally uses the Move language for fast and secure transaction execution. The Move prover, a formal verifier for smart contracts written in the Move language, provides additional safeguards for contract invariants and behavior. This focus on security allows developers to better protect their software from malicious entities.Second, the Aptos data model enables flexible key management and hybrid custodial options. This, alongside transaction transparency prior to signing and practical light client protocols, provides a safer and more trustworthy user experience.Third, to achieve high throughput and low latency, the Aptos blockchain leverages a pipelined and modular approach for the key stages of transaction processing. Specifically, transaction dissemination, block metadata ordering, parallel transaction execution, batch storage, and ledger certification all operate concurrently. This approach fully leverages all available physical resources, improves hardware efficiency, and enables highly parallel execution.Fourth, unlike other parallel execution engines that break transaction atomicity by requiring upfront knowledge of the data to be read and written, the Aptos blockchain does not put such limitations on developers. It can efficiently support atomicity with arbitrarily complex transactions, enabling higher throughput and lower latency for real-world applications and simplifying development.Fifth, the Aptos modular architecture design supports client flexibility and optimizes for frequent and instant upgrades. Moreover, to rapidly deploy new technology innovations and support new web3 use cases, the Aptos blockchain provides embedded on-chain change management protocols.Finally, the Aptos blockchain is experimenting with future initiatives to scale beyond individual validator performance: its modular design and parallel execution engine support internal sharding of a validator and homogeneous state sharding provides the potential for horizontal throughput scalability without adding additional complexity for node operators.
