Aptos — Operating System

← Target Reference | VM: MOVEVM

Runtime Parameters

Parameter Value
VM MOVEVM
Runtime binding aptos.ext.*
Account model Account-centric (resources)
Storage model Resource storage
Cost model Gas
Cross-chain --

Runtime Binding (aptos.ext.*)

  • Account resources — read and modify resources stored under accounts
  • Tables — scalable key-value storage for large collections
  • Coin operations — mint, burn, transfer via the coin module
  • Multi-agent transactions — transactions signed by multiple accounts

Notes

Aptos uses an account-centric resource model — each account stores typed resources that are governed by Move's linear type system. Resources cannot be copied or implicitly dropped, ensuring asset safety at the type level.

Block-STM provides optimistic concurrency for parallel execution. Transactions are speculatively executed in parallel, and conflicts are detected and resolved via re-execution, achieving high throughput without requiring explicit dependency declarations.

The Move type system on Aptos enforces module-level encapsulation — resources can only be created, moved, or destroyed by the module that defines them.

For MOVEVM details (instruction set, lowering path, bytecode format), see movevm.md.
