DNSSEC stands for Domain Name System Security Extensions. It is a set of security protocols designed to protect the integrity and authenticity of DNS data.In systems using DNS, domain names are translated into IP addresses. However, without proper security, this process is vulnerable to attacks, such as cache poisoning, where users are misdirected to malicious sites. DNSSEC addresses this vulnerability by adding digital signatures to DNS records.When a user queries a domain, DNSSEC ensures that the response is valid and has not been altered. This is done through cryptographic signing of the DNS data, allowing clients to verify that the information they receive is from a legitimate source. In the context of cryptocurrencies, using DNSSEC can help protect wallet addresses, transactions, and smart contracts from fraud or manipulation. Ensuring that users connect to the correct addresses reinforces trust in transactions and services.Implementing DNSSEC can enhance the overall security landscape, making it more difficult for attackers to exploit DNS vulnerabilities and ensuring safer interactions within the ecosystem.
