## Public Key Infrastructure Evolution

Public Key Infrastructure Evolution involves the transition from traditional, centralized certificate authorities to decentralized, blockchain-based trust models. In traditional finance, PKI relies on centralized entities to issue and verify certificates, creating single points of failure and control.

In the crypto domain, the evolution moves toward decentralized systems where users and protocols can verify trust directly via blockchain records. This shift is fundamental for the security of derivatives platforms, as it ensures that the keys used for signing trades and contracts are verified through transparent, immutable processes.

It reduces reliance on fallible intermediaries and aligns the infrastructure with the decentralized nature of digital assets. This evolution is necessary to scale trust in a global, permissionless market where traditional certificate models are insufficient.
