Code is executed as written" means that:

1. _Immutable code_: The code is stored on the blockchain and cannot be altered.

2. _Tamper-proof execution_: The code is executed exactly as written, without any modifications.

3. _No intermediate manipulation_: The code is run directly on the blockchain, without any intermediate layers.

4. _Deterministic output_: The code execution produces a predictable and consistent output.

This principle ensures that:

1. _Trustless execution_: Code is executed without relying on a central authority.

2. _Transparency_: Code is visible and verifiable.

3. _Security_: Code is protected from tampering and manipulation.

4. _Consistency_: Code execution is consistent and predictable.

By executing code exactly as written, blockchain smart contracts guarantee a high level of security, transparency, and reliability, enabling a wide range of decentralized applications and use cases!
