# Mode Synth (SN50) Subnet Whitepaper and How to Guide

The creation and use of synthetic price data has traditionally been dominated by opaque, well-funded entities such as large financial institutions, centralized technology firms, and regulatory agencies, including JPMorgan Chase, Goldman Sachs, the Federal Reserve, and PayPal. The closed-source nature of these datasets stems from the self-serving priorities of these organizations, which often lack the incentive to democratize data access. This approach exacerbates disparities, creating a wider gap between everyday users and those with greater resources.

In the whitepaper linked below, we demonstrate that it is possible to generate useful synthetic data in a decentralized manner, using the Bittensor ecosystem and land the use case in DeFi Agents. We argue that a synthetic data layer will become a crucial step for DeFi to reach mass adoption, through autonomous and evolving AI Agents.

Synth is a pioneering subnet on the Bittensor network, designed to provide high-fidelity synthetic price data for the emerging agentic economy. By addressing the limitations of real-world datasets, Synth creates a robust foundation for AI-driven decision-making, transforming DeFi workflows and expanding into new industries.

Check out our complete guide on how to setup your first model.

In the guide linked below, we break things down into three key areas:

1.  Explaining the Scoring System: What’s the methodology behind how submissions are evaluated?
    
2.  Tutorial for Miners: How to set up and submit Bitcoin price predictions using a simple Geometric Brownian Motion (GBM) model.
    
3.  Sandboxed Competition Results: A look at how miners using similar models, like GBM, perform against each other.
