Djuno

This project represents the Juno implementation for the Desmos blockchain.

It extends the custom Juno behavior with custom message handlers for all the Desmos messagejuno. This allows to store the needed data inside a PostgreSQL database on top of which GraphQL APIs can then be created using Hasura

Installation

To install the binary simply run make install.

Note: Requires Go 1.13+

Database

Before running the parser, you need to:

1. Create a PostgreSQL database.
2. Run the SQL queries you find inside the *.sql files in the schema folder inside such database to create all the necessary tables.

Running the parser

To parse the chain state, you need to use the following command:

djuno parse <path/to/config.toml>

# Example
# djuno parse config.toml 

The configuration must be a TOML file containing the following fields:

rpc_node = "<rpc-ip/host>:<rpc-port>"
client_node = "<client-ip/host>:<client-port>"

[database]
host = "<db-host>"
port = <db-port>
name = "<db-name>"
user = "<db-user>"
password = "<db-password>"
ssl_mode = "<ssl-mode>"

Example of a configuration to parse the chain state from a local full-node:

rpc_node = "http://localhost:26657"
client_node = "http://localhost:1317"

[database]
host = "localhost"
port = 5432
name = "desmos"
user = "<username>"
password = "<password>"
