Why Move

Move is a safe and secure programming language designed by Facebook for smart contracts that emphasizes ownership and safety. Assets in Move are represented as resources. Owing to Move's strong ownership model and explicit resource abilities, Move simplifies the development of safe smart contracts for common blockchain tasks such as transfer ownership of assets, minting, and destroying. The chart below compares common non-Move runtimes against Aptos and Sui Move runtimes, underscoring the different models and benefits of Move.

The chart below compares common non-Move runtimes against Aptos and Sui Move runtimes, underscoring the different models and benefits of Move.

	Aptos / Move	Solana / SeaLevel	EVM	Sui / Move
Data storage	Stored at a global address or within the owner's account	Stored within the owner's account associated with a program	Stored within the account associated with a smart contract	Stored at a global address
Parallelization	Capable of inferring parallelization at runtime within Aptos	Requires specifying all data accessed	Currently serial nothing in production	Requires specifying all data accessed
Transaction safety	Sequence number	Transaction uniqueness	Nonces, similar to sequence numbers	Transaction uniqueness
Type safety	Module structs and generics	Program structs	Contract types	Module structs and generics
Function calling	Static dispatch	Static dispatch	Dynamic dispatch	Static dispatch
Authenticated Storage	Yes	No	Yes	No
Object accessibility	Guaranteed to be globally accessible	Not applicable	Not applicable	Can be hidden
