What is out-of-band Protocol?

Another scenario arises when agents are already connected but lack identification of the counterpart. This ambiguity can hinder effective communication, making the Out-of-band protocol indispensable for verifying the identity of the other party and ensuring the integrity of the exchange.

The Out-of-band protocol serves a crucial purpose in scenarios where an agent lacks certainty about its connectivity status with another agent. This uncertainty can stem from various reasons, each necessitating the employment of this protocol.

One such reason is when an agent endeavors to establish a fresh connection with another. In such instances, the Out-of-band protocol acts as a bridge, facilitating the initial handshake and ensuring a secure communication channel is established.

Furthermore, the Out-of-band protocol caters to the need for connection-less interactions. In situations where a persistent connection is not feasible or desired, this protocol enables agents to engage in temporary, secure exchanges without the overhead of maintaining a continuous link.
