Building Secure Foundations on Solana

Our current focus is on security and integration — bringing together the different Solana programs that power TCW into a single, cohesive system with a strong central authority.

This is not about NFTs, speculation, or play-to-earn mechanics.
Solana serves as the core infrastructure for TCW's economic simulation, acting as a secure and verifiable backbone for trade, governance, and value flows across the galaxy.

Strengthening the Core

Over time, several independent programs have been developed, each handling a different aspect of TCW’s economic infrastructure.
Our current work focuses on bringing these components together into a unified, secure environment where all activity is validated by the same central authority.

Here’s how each program fits into the system:

• tcw-core – Structural registry and guardians.
  Tracks the programs and service versions that make up the blockchain layer of TCW.
  It defines global guardians, special keys that can authorize system-level actions, such as initializations, security handshakes, or operations above the SYS_ADMIN role.
  There are no per-user permissions here — only structural control at the highest level.

• tcw-auth – Role-based access control.
  Provides a simple RBAC model: entities are assigned roles, and those roles determine what they can do.
  There are no individual permissions or complex policies — just clear, predefined roles that keep the system straightforward and predictable.

• tcw-treasury – Internal treasury and payment manager.
  Acts as the financial heart of the system, handling both on-chain and off-chain expenses.
  It receives capital inflows from sources such as the marketplace, ICOs, or real-world funding, and distributes them across three key pools:

  • Operational Pool – Covers Solana rent, transaction fees, and other ongoing blockchain costs.
  • Development Pool – Funds infrastructure, cloud services, and on-prem operations.
  • General Liquidity Pool – Maintains long-term financial stability for the project.
    The goal of the treasury is sustainable growth, not profit: balancing necessary spending with long-term accumulation.

• tcw-survey – Registry of Worlds and Trade Routes.
  Maintains the authoritative map of the galaxy’s economy:

  • Worlds (nodes): represent local markets and production centers.
  • Trade Routes (edges): represent connections between worlds for commerce and information flow.
    This registry is the foundation of the economic graph, defining the structure on which all analytics and simulations are based.

• tcw-graph – Analytical tools for economic state and latency.
  Provides fast analysis tools, operating on the network defined by tcw-survey.
  These tools are used both on-chain and off-chain to:

  • Calculate informational and commercial latencies between any two nodes.
  • Generate diff-based state views, showing how one node perceives another at a given time.
  • Support decision-making by modeling delays, trade imbalances, and shifting market conditions.

By integrating these programs into a single secure framework, we ensure that every process — from high-level structural changes to real-time market analysis — operates under consistent rules and trusted validation.
This unified foundation is essential for the stability and growth of TCW’s economic simulation.

Security as the Foundation

A unified system only works if its foundation is secure.
This week, we've been focused on:

• Centralized security so all programs operate under the same authority.
• Defining clear roles to prevent conflicts or privilege leaks.
• Ensuring integrity of every action recorded on-chain.

By locking down these fundamentals, we prevent exploits and ensure the galaxy’s economy remains stable, transparent, and tamper-proof.

Preparing for Service Integration

Once this secure base is in place, we can begin integrating additional services — such as market systems, exploration layers, or external tools — into the unified environment.

This preparation is essential because:

• New services will inherit the central security policies automatically.
• Integration will be predictable and controlled, with no surprises.
• The economic simulation will scale safely as TCW grows.

Looking Ahead

The immediate goal is clear: complete the integration of our core programs into a single, secure system.
From there, we will connect this foundation to player-facing features and the in-game economy, ensuring every trade, contract, and decision follows consistent and verifiable rules.

This week has been about laying the groundwork — transforming a collection of separate components into a single, reliable foundation for TCW’s economic simulation.
