The problem CryptShield solves

CryptShield is a blockchain application designed to safeguard users from malicious hackers and malware. It provides a security service that allows developers and users to understand who people are interacting with when producing smart contracts.

The application targets users through a blockchain-based verification and blacklisting procedure. It includes a piece of code that any developer may use to create a smart contract. That contract then communicates with the corresponding CryptShield's smart contract and queries a database of known dangerous users.

Each user in their database has a unique score that reflects the threat of engaging with them; this includes tracking users of denial-of-service attacks, stealing money from smart contracts, and other malicious activity. This piece of code prevents smart contracts from engaging with these people and causes the activity to fail instantly.
