Description: Abuse prevention in the context of blockchain interoperability refers to the measures and protocols implemented to prevent the misuse of systems and services based on blockchain technology. This includes protection against fraud, cyberattacks, and malicious use of data. Blockchain interoperability allows different networks and blockchain systems to communicate and operate together, expanding the possibilities for collaboration and efficiency. However, this interconnection can also introduce vulnerabilities if not managed properly. Therefore, abuse prevention becomes a critical aspect of ensuring trust and security in these interactions. The main features of these measures include robust authentication, data encryption, transaction auditing, and continuous monitoring of suspicious activities. The relevance of abuse prevention lies in the need to maintain the integrity and reputation of blockchain platforms, as well as in protecting users and their digital assets. Without adequate abuse prevention, interoperability could be compromised, negatively affecting the adoption and development of blockchain-based solutions.
