# BuidlGuidl Nodes Setup in Nigeria

## Project Overview
This project aims to enhance Ethereum's decentralization in Nigeria through the deployment and operation of two BuidlGuidl nodes. The initiative includes hardware procurement, node setup, and the onboarding of local RPC operators to maintain the infrastructure.

## Current Progress
We have successfully initiated the first phase of the project with one node deployment. The second phase, including the setup of an additional node, is pending further funding.

## Hardware Specifications
The current node configuration includes:

GraphQL Cheat Sheet

Overview

• An alternative approach to RESTful APIs
• Clients issue queries/mutations to read and update data
• Clients can fetch only the entity fields that are required
• GraphQL query syntax can express complex entity relations => nested objects
• Mitigates the explosion of RESTful endpoints in scenarios where many different representations of an entity are needed
• Graphiql is a query execution UI, also provides good documentation
