Best practice
Use "proof of confidence" when you want to emphasize that a particular action or event serves as tangible evidence that someone or some group has confidence in something. This phrase is especially useful when the confidence might otherwise be questioned or doubted.
Common error
Avoid using "proof of confidence" when you simply mean 'expression of hope' or 'statement of optimism'. The phrase specifically implies that there's existing evidence to back up the sentiment, so using it loosely can dilute its impact and make your writing less precise.
