Aleo Proving Pool Server

Introduction

A Proving pool server for the Aleo network.

Why a Standalone Server?

This is explaining why this project was created during Testnet2 period.

1. I want to separate the mining pool part from the network node as ledger syncing sometimes interferes with the mining pool operations.
2. I want to use a more efficient network protocol for pool - miner communication.
3. Making too many changes to the snarkOS code could be a bad idea as I still need to sync with upstream code.
4. It's easier to test the mining pool with a standalone server.
5. It's also easier to add more features to a smaller codebase.

Features

1. A stratum protocol. Specs.
2. A good enough automatic difficulty targeting system. (Needs more test under high load)
3. Stats for pool and provers.

State

Undergoing a lot of rewrite:

• Use RDBMS instead of RocksDB for most of the data storage
• Use a real stratum protocol for pool - miner communication
• Rework the difficulty targeting system
• Decide if more API endpoints are needed -- many of the work should be offloaded to frontends
• Payout system step 1 - allocate rewards to provers after confirmation
• Payout system step 2 - send rewards to provers (indefinitely delayed until the network is ready)

Things to test

• If new blocks can be properly generated
• If the payout system works
• If the difficulty retargeting system works under high load - Works under light load
• If there is no deadlock under high load - Works under light load

Usage

Don't use unless you know what you're doing for now.

System requirements

• Rust 1.77+ (Not sure what's strictly required)

Optional:

• PostgreSQL 11+ (Still not sure what's strictly required)
• PL/Python 3.6+
