## What We Use Blockchain For

The protocol does not use blockchain for speculation or token emissions—it uses programmable escrow and transparent settlement to make real trade finance more efficient.

### Programmable Escrow

Smart contracts hold assets and funds with predefined rules:

* No party can unilaterally access funds
* Settlement triggers are automatic and transparent
* Disputes follow on-chain resolution paths

### Transparent Settlement

All transactions are visible on-chain:

* Asset submissions and verifications
* Funding events
* Maturity and settlement
* Default and recovery

### Global Access

Anyone with an internet connection can:

* Submit assets for financing (after KYB)
* Invest in trade finance yields (after KYC)
* Participate 24/7, regardless of time zone

### Fractional Participation

Blockchain enables:

* Splitting large invoices into smaller investments
* Lower minimum investment thresholds
* Broader investor participation
