How Does the Public Nature of Blockchains Affect the Security of Smart Contracts?

The public nature of blockchains means that anyone can view the code of a smart contract, as well as all of the transactions that have been executed on it. This transparency can be a double-edged sword.

On one hand, it allows for public scrutiny and can help to identify vulnerabilities. On the other hand, it also makes it easier for attackers to find and exploit those vulnerabilities.
