'''Ed25519''' is a public-key signature system designed by Daniel J. Bernstein and collaborators in 2011, built on the twisted Edwards curve Curve25519 rather than the Weierstrass curves used by traditional [[ECDSA]]. It provides deterministic signatures, fast constant-time implementations that resist timing attacks, and compact 64-byte signatures — addressing the catastrophic failure modes that have plagued ECDSA in practice, most notably the nonce-reuse vulnerability that exposed the Sony PlayStation 3 private key in 2010.

Ed25519 has displaced ECDSA as the default in [[OpenSSH]], Signal, and numerous modern protocols. Its design philosophy treats implementation safety as a first-class constraint rather than an afterthought: the algorithm is engineered to be difficult to misuse, even by developers who do not understand elliptic curve mathematics. This represents a shift in cryptographic design from 'correct if implemented perfectly' to 'correct if implemented at all' — a systems-level recognition that the weakest link is rarely the mathematics and almost always the programmer.

The efficiency of Ed25519 is not merely a technical improvement. It is a case study in how engineering refinement can displace an entrenched standard without breaking the underlying hardness assumption. Both ECDSA and Ed25519 rely on the [[Discrete Logarithm Problem|elliptic curve discrete logarithm problem]]; the difference is entirely in the implementation surface.
