Delegation Strategy

This repository contains all necessary components to track and collect validators' data and evaluate them for the purposes of Marinade's stake distribution.

Repository structure

• Rust API to expose all validators' data
• Rust CLI tool to collect a snapshot from the Solana chain
• Rust CLI tool to store previously collected data to DB
• DB migration scripts
• A set of scoring and utility scripts

Scoring

Replicate official reports

Follow the steps described for each report on the staking reports page

Create a new report

Prerequisities:

• R installed
• R packages installed (run from the cloned repository):

./scripts/scoring-install.bash

Inside the cloned repository run:

./scripts/scoring-fetch-inputs.bash                   # To fetch the latest data from API
./scripts/scoring-run.bash                            # To generate scores
./scripts/scoring-report.bash "- development version" # To generate report.html

Development

Prerequisities

• Rust - for development of data collection, storing and serving
• PostgreSQL - for the storage
• R - for the scoring calculations

Env

Create a .env file after cloning the repository

POSTGRES_URL=postgresql://...
RPC_URL=https://api.mainnet-beta.solana.com
