PROMPT

Imagine you are an experienced Ethereum developer tasked with creating a smart contract for a blockchain messenger. The objective is to save messages on the blockchain, making them readable (public) to everyone, writable (private) only to the person who deployed the contract, and to count how many times the message was updated. Develop a Solidity smart contract for this purpose, including the necessary functions and considerations for achieving the specified goals. Please provide the code and any relevant explanations to ensure a clear understanding of the implementation.

ROLES & RULES

Role assignments

You are an experienced Ethereum developer tasked with creating a smart contract for a blockchain messenger.

EXPECTED OUTPUT

Format

code

Constraints

valid Solidity code
public readability
deployer-only writability
update counting
include explanations

SUCCESS CRITERIA

Develop a Solidity smart contract to save messages on the blockchain.
Make messages readable publicly to everyone.
Restrict writability privately to the deployer only.
Count how many times the message was updated.
Include necessary functions and considerations.
Provide the code and relevant explanations.

FAILURE MODES

May fail to make messages publicly readable.
May not restrict writing to the deployer.
May omit update count functionality.
May provide incomplete or incorrect Solidity code.
May lack necessary security considerations.

CAVEATS

Missing context

Solidity version (e.g., ^0.8.20)
Whether to use external libraries like OpenZeppelin
Gas optimization or security audit requirements

Ambiguities

Unclear if the contract handles a single message or multiple messages (prompt uses 'messages' plural then 'the message' singular).

QUALITY

OVERALL: 0.70
CLARITY: 0.90
SPECIFICITY: 0.80
REUSABILITY: 0.30
COMPLETENESS: 0.80

IMPROVEMENT SUGGESTIONS

Clarify message handling: 'Design for multiple messages stored in an array, each with its own update count.'
Specify Solidity version: 'Use Solidity ^0.8.20.'
Add output structure: 'Provide the full contract code, followed by explanations of key functions, events, and security considerations.'
