How to Implement the Beckon Protocol: Step‑by‑Step Guide

Adopting the Beckon protocol starts with studying the specification hosted on GitHub. Teams then define the domain—such as mobility—and identify sub‑domain use cases, for example shared cabs versus rental services. By narrowing the scope, developers create a domain‑specific instance of the core specifications that restrict fields and objects to those needed for the chosen use case. The next step generates an asymmetric key pair; the platform retains the private key while publishing the public key to the registry. After the domain instance is ready, developers implement the protocol stack, which includes the Beckon API, any required domain APIs, and the client‑side UI if desired. Finally, the platform undergoes certification, registers with the appropriate registry, and subscribes to the network to maintain active participation.

Protocol Stack Layers

Beckon defines four asynchronous APIs—search, select, init, and confirm. Because most mobile applications operate synchronously, a translation layer maps these async calls to synchronous client behavior. Two common translation methods are polling, using a “check search” API that the client invokes periodically, and WebSockets, which keep an open socket for real‑time callbacks. The client‑side API layer then exposes either polling or WebSocket endpoints to the mobile UI, which remains optional. A platform must be certified and registered before it can transact on the network.

Registry Infrastructure

The registry functions as a chain of trust, mirroring the DNS model. It stores flat lookup tables containing subscriber IDs, types, endpoints, and cryptographic keys. Registries exist in a hierarchy: local registries report to country‑level registries, which in turn report to a root registry. Platforms call the “subscribe” API at least once every 24 hours to signal continued availability; failure to do so removes the platform from active discovery. Gateways (BGs) use the “lookup” API to discover Buyer/Seller Platforms (BPPs) based on domain, city, and country, enabling cross‑region transactions.

Cross‑Region Discovery (DNS‑style Lookup)

1. A local gateway queries the Root Registry to obtain a list of country‑level registries.
2. The gateway contacts the appropriate Country Registry to retrieve city‑level registries.
3. The gateway then queries the Local Registry for BPPs that match the required domain and location.
4. Finally, the gateway broadcasts the request to the discovered BPPs, completing the discovery cycle.

Asynchronous‑to‑Synchronous Mapping

The translation layer bridges Beckon’s async protocol with the synchronous flow of a user’s mobile session. With polling, the client repeatedly calls a “check” API until a response arrives. With WebSockets, an open socket delivers callbacks instantly, eliminating the need for repeated requests. This layer ensures that the user experience remains seamless despite the underlying asynchronous network operations.

“The registry infrastructure is the one which actually allows authentication of every transaction.”

“This registry infrastructure has been sort of modeled after the DNS infrastructure in a very similar way.”

“It’s not necessary that every commerce network is going to utilize every single aspect, every field of the specification.”

“Once you have implemented your protocol stack and you’re listed on your registry, then you are ready to transact on the network.”

The Beckon specification supports over 10 million e‑commerce use cases, demonstrating its scalability across diverse domains.
