Cryptographic Handshakes

Cryptographic handshakes are the initial communication protocols that two nodes perform to establish a secure, encrypted connection. During this process, nodes exchange public keys, negotiate encryption algorithms, and verify each other's identity.

This ensures that the subsequent data transmission is private and protected from eavesdropping or tampering. In a P2P network, these handshakes are essential for preventing man-in-the-middle attacks, as they establish a trusted channel before any sensitive transaction or consensus data is exchanged.

The handshake also allows nodes to detect if a peer is running an incompatible or malicious version of the software. By enforcing strict security during the connection setup, the protocol protects the integrity of the P2P layer.

This is a foundational step in building a resilient decentralized network, as it ensures that all communication occurs within a secure, authenticated environment, which is vital for the stability of financial derivative contracts.
