Aptos is a Layer 1 blockchain using the Move programming language with parallel execution (Block-STM), built by former Meta engineers to deliver high throughput and low latency.
WHY IT MATTERS
Aptos shares roots with Meta's abandoned Diem project, carrying forward the Move language and many architectural ideas. Its Block-STM execution engine detects transaction dependencies at runtime and executes independent transactions in parallel.
The focus is on enterprise and institutional use cases — the team's background at Meta lends credibility for large-scale deployment. Transaction throughput targets are in the tens of thousands TPS range.
Aptos and Sui are often compared as the two major Move-based L1s. While sharing the language, their architectures differ significantly in consensus, execution, and data models.
FREQUENTLY ASKED QUESTIONS
Aptos vs Sui?
Both use Move but differ in architecture. Aptos uses Block-STM for parallel execution. Sui uses an object-centric model. Aptos feels more enterprise-focused; Sui more consumer-focused.
What is Block-STM?
A parallel execution engine that optimistically executes transactions simultaneously, then detects conflicts and re-executes conflicting ones. This achieves parallelism without requiring developers to specify dependencies.
Is Move better than Solidity?
Move provides stronger safety guarantees (resources can't be duplicated or destroyed) but has a smaller ecosystem and developer community. Solidity has more tooling, auditors, and battle-testing.
