 ## EdDSA (Edwards-Curve Digital Signature Algorithm)
 
-### **Overview**

 EdDSA is a modern digital signature algorithm based on elliptic curve
 cryptography. It is specifically designed to be more efficient, secure, and
 resistant to common implementation errors compared to older algorithms like DSA
 or ECDSA.
