Discovery of Beckn Platform via Search Technology [C4GT]

[dhirajshettyyy]

Description

This proof of concept is to evaluate how search engines can be used to index Beckn websites and make them discoverable. It is an alternate model to a central registry-based mechanism.

Goals

BPP

• BPP to host a signed Beckn descriptor file on their domain issued by a certification authority.
• Search engines should be able to verify this descriptor and index their catalog.
• BPPs should be able to push changes to their catalog incrementally to the search engine(s).

Bap

• BAP can also host a signed Beckn descriptor file on their domain issued by a certification authority.
• BAPs can discover Bpps and their products via search engines (like Beckn gateway)
• BPPs should be able to verify Baps signatures using the BAP's Beckn descriptor.

Expected Outcome

Peers should be able to verify each other and transact as an open network with no central controlling facilitator.

Objective outcomes:

1. Product Design (UX, Architecture)
2. Source code for Search Provider, Integration with BAP & Integration with BPP.
3. Application hosted on FIDE AWS
4. Demo video recording of search provider integrated with retail BAP & two retail BPPs

Acceptance Criteria

• Beckn reference Gateway to be enhanced to function as a search engine.
• A Reference Bpp should be able to push catalog changes to the gateway
• Reference Bap should be able to choose the gateway as a search engine for discovery purposes.

Implementation Details

1. A github repo consisting of certification authorities ,search engines and their Public keys.
2. Beckn.json (beckn descriptor) file can be signed by one of the authorities.
3. The authority may host the beckn registry for validating endpoints and keys.
   *. Once validated, the apps will be issued a beckn.json file affixed with their signature.
4. Lucene to be used for indexing the catalog.
5. /search of gateway to look into local indexed catalog
6. unsolicited /on_search from bpp to be used to push full/part catalog

Do not ask process related questions about how to apply and who to contact in the above ticket. The only questions allowed are about technical aspects of the project itself. If you want help with the process, you can refer instructions listed on Unstop and any further queries can be taken up on our Discord channel titled DMP queries. Here's a Video Tutorial on how to submit a proposal for a project.

The current design for the registrar:

1. Onboard companies and their apps and perform their kyb , verify app endpoints and keys.
2. Have an ability to generate beckn.json
   { "content" :"a base64 encoded json" , "signature" : "of the registrar for the content using registrar's private key" }
3. The content schema has the following content:
   {"subscribers": [] , "organization" : {} , "payment" : {"collected_by" : "BAP|BPP" , "params" : {..banking_details...} }, "registrar_id" : "the registrar's subscriber_id of type LREG" }

An implementation of this registrar is hosted @ humbhionline

For BGS , BAPS and BPPS

1. host the signed beckn descriptor json at well-defined-path/beckn.json
2. On Receiving signed payloads, check the counter party' /beckn.json , verify registrar's signature using registrar's public key . Then verify the signature of the counter party using the public key published in the context of beckn.json and continue with processing as usual.
