Our Solutions
TrustyCity provides the software and cryptographic infrastructure to implement the Trust Theory of Money in real-world financial systems. Our solutions are designed to extend the current monetary system — not replace it — by adding the trust-measurement layer that has always been missing.
TTM Transaction Engine
The core of TrustyCity's offering is a privacy-preserving, cryptographically verifiable transaction system based on modular arithmetic with homomorphic properties.
How it works: An issuer (Γ) publishes a spendable digital check backed by a legally formalized pledge. Holders of that check can transact with any other party who trusts the issuer, spending fractional amounts while keeping the transaction value private. The system enforces the privacy principle: parties are publicly identified, but only buyer and seller know the amount.
Key properties:
- Transaction amounts are private to the transacting parties; all other data is public and independently verifiable
- No decryption is ever required — the construction is inherently more secure than RSA and not vulnerable to quantum attacks
- Any third party can verify that a transaction is valid without learning the transaction amount
- Wallet states are locked during transactions to prevent double-spending

Checkpoint Trust Scoring
Bureaucratic credentials are targets — and Goodhart's Law ensures they are gamed. TrustyCity's trust scoring system gathers data at checkpoints embedded in natural economic activity, producing a continuous trust profile that cannot be studied for or manipulated in isolation.
How it works: Every fulfilled pledge, every completed transaction, every honored commitment becomes a data point. The system aggregates these checkpoints into a trust score that determines how much credit any party can issue and how readily others will accept it.
Key properties:
- Continuous, checkpoint-based evaluation resistant to Goodhart's Law
- Trust scores determine issuer limits, not gatekeepers
- Transparent track records enable informed decisions by all counterparties
- Failed pledges are recorded and reflected, just like a missed payment on a credit report
B2B Integration APIs
For banks, credit bureaus, and financial infrastructure providers, TrustyCity offers libraries and APIs that allow existing systems to participate in the TTM ecosystem without replacing current infrastructure.
Capabilities:
- Wallet state management and verification
- Pledge agreement registration and tracking
- Trust score queries and updates
- Transaction verification endpoints
B2C Trust Applications
For individuals and small institutions, TrustyCity is developing mobile applications that make trust data legible, actionable, and useful for everyday economic decisions.
Capabilities:
- View and manage your trust profile
- Evaluate issuers before accepting their checks
- Track the pledge lifecycle from issuance to redemption
- Analyze your transaction history and trust trajectory
What Makes TTM Different
| Fiat Money (MMT) | Cryptocurrency | TTM | |
|---|---|---|---|
| Value source | Government guarantee | Artificial scarcity | Verifiable issuer trust |
| Accountability | Unconditional for governments | Hidden (miners/whales) | Checkpoint-based for all |
| Privacy | Varies | None (public ledger) | Enforced cryptographically |
| Decentralization | Single issuer per currency | Nominally decentralized | Unlimited independent issuers |
| Scarcity | Managed by central bank | Hard-coded | Emerges from trustworthy issuance |
| Quantum resistance | Varies | Vulnerable (some schemes) | By design — no decryption needed |
