How BLUE SOIL tokens and the Roker ROSCA interlock to create a self-reinforcing community finance loop — access, governance, savings, and reward in one closed sovereign circuit.
| Stage | BLUE SOIL Role | ROSCA Role |
|---|---|---|
| Entry | Minimum BST holding required | ROSCA round access granted |
| Governance | BST holders vote on parameters | Round structure determined |
| Operation | BST staking optional during round | Contributions collected, recorded on Truth Ledger |
| Distribution | BST rewards for on-time contributors | Full pool distributed to rotating winner |
| Reinvestment | Winners can convert to dPRN or restake BST | Completed rounds generate new cycle invitation |
| Instrument | Function | Backing | Revenue Stream |
|---|---|---|---|
| dPRN | Commercial plastic verification | £450/tonne physical plastic | Processing fees, verification premiums |
| Blue Soil Token (BST) | Community regeneration value | Verified environmental action | Token exchange, service credits |
| ROSCA (Roker) | Community savings pooling | Member contributions (cash/dPRN/BST) | Financial inclusion + dPRN flow |
The integration protocol between BST and ROSCA was designed to answer a specific question: how do you make community finance sustainable without making it complicated? The answer is interlocking incentives. When BLUE SOIL tokens are required for ROSCA access, token holders are motivated to participate consistently — because missing a round means losing their access window. Consistent participation is the engine of the ROSCA's power.
The optional dPRN conversion at the point of ROSCA payout is the most elegant feature of the integration. A community member who wins their ROSCA round can choose to take cash, hold BST, or convert to dPRN at the sovereign price. If they choose dPRN, they are now a holder of a verified circular economy asset. They have moved from community finance into sovereign infrastructure in a single transaction. This is how communities are brought into the circular economy without ever being asked to "invest in sustainability." They are simply saving money, winning their turn, and choosing their exit.
The Truth Ledger records every transaction in both systems — every BST transfer, every ROSCA contribution, every distribution. This creates a permanent, auditable history of community financial activity that can also serve as proof of income for participants who have historically struggled to demonstrate financial reliability to formal institutions.
