Bade generator

The purpose of this service is to generate and provide a badge, of which consumers can use when communication with providers.

Configuration

The badge server uses a config file named badgeserver.yml that provides the projects data and some other basic configuration. An example for a configuration file:

projects-data:
	2:
		myWeb3Project:
			epochs-max-cu: 100000

default-geolocation: 2

countries-file-path: ""
ip-file-path: ""

projects-data - hold a map of maps of geolocation to project to project's data. In this example, there is only one project, under geolocation 2 , named myWeb3Project. epochs-max-cu - defines the max CU that can be used for this project per epoch. default-geolocation - the default geolocation to use, when one cannot be determined by the badge server. countries-file-path - path of the countries file ip-file-path - path of the IP file

Countries File

This is a CSV file with all countries and lava-geolocation link for example. It contains four columns: country-code, country-name, continent code and lava-geolocation. Example:

AD;Andorra;EU;2
AE;United Arab Emirates;AS;2
AF;Afghanistan;AS;2
AL;Albania;EU;2
AM;Armenia;AS;2
AO;Angola;AF;2
IP File

This is a TSV file with all IP ranges and country code that they belong to. Tt can be downloaded from this website, under ip2asn-v4.tsv. It contains 5 columns: range_start, range_end, AS_number, country_code and AS_description. Example:

1.0.0.0	1.0.0.255	13335	US	CLOUDFLARENET
1.0.1.0	1.0.3.255	0	None	Not routed
1.0.4.0	1.0.5.255	38803	AU	WPL-AS-AP Wirefreebroadband Pty Ltd
1.0.6.0	1.0.7.255	38803	AU	WPL-AS-AP Wirefreebroadband Pty Ltd
1.0.8.0	1.0.15.255	0	None	Not routed

Running the badgeserver

To run the badge server, run this command:

lavad badgeserver [config-path] --port=[port] --log_level=[log level] --chain-id=[chain id]

Where config-path is the directory which contains the badgeserver.yml file.

Generating a Badge

To generate a badge, use the RPC endpoint lavanet.lava.pairing.BadgeGenerator/GenerateBadge. The input for this endpoint is: badge_adress - the client wallet address that uses the badge. This address must match to the transactions signer address. project_id - the project ID to use. spec_id - the spec to generate the badge for.

The response of this request is: badge - and object, holding the following data:

  • cu_allocation
  • epoch
  • address
  • lava_chain_id
  • project_sig
  • virtual_epoch

get_pairing_response - the response from a pairing query, made automatically by the badge server on badge generation. badge_signer_address - the public address of the badge signer. spec - the full spec of the requested spec_id

const AddBlockDelayForEpochUpdaterBadgeServer = 2

adding 3 blocks delay, to update the epoch. the reason is for the sdk to wait until all providers are synced to the new epoch before SDK gets a new pairing list.
