Token Flows

GCoin (G) is the native utility and settlement token of the PlayBlock ecosystem. Its flow is intentionally simple, deterministic, and fully observable on-chain.

Every movement of GCoin follows strict rules designed to ensure:

• Transparency

• Auditability

• No hidden balances

• No off-chain manipulation

This document describes how GCoin moves, who controls it, and why the model is safe by design.

High-Level Principle

GCoin never moves implicitly.

Every GCoin transfer is:

• Initiated by a smart contract

• Executed on-chain

• Visible in the PlayBlock explorer

• Final and deterministic

There are no internal ledgers, no virtual balances, and no off-chain settlement.

Core Actors in the GCoin Flow

GCoin moves between a small, well-defined set of actors:

1. User Wallets

2. Product Treasuries

3. System Executors (Relayers)

4. Reward Distribution Contracts

5. Liquidity & System Vaults

Each actor has a single responsibility and limited permissions.

Primary GCoin Flow Paths

1. User → Treasury (Spending GCoin)

This is the most common flow.

When it happens

• Casino bets

• Prediction bets

• Game entry fees

• Any paid interaction

Flow

User Wallet → Product Treasury

Properties

• Triggered by a smart contract call

• Funds leave the user wallet immediately

• Treasury balance increases atomically

• No intermediary custody

This ensures the system never holds user funds off-chain.

2. Treasury → User (Winnings & Payouts)

When a user wins, GCoin is paid directly from the treasury.

Flow

Product Treasury → User Wallet

Key properties

• No batching delays

• No internal accounting

• One transaction per payout

• Fully traceable winner → treasury → tx hash

This guarantees that winnings are real funds, not credits.

3. Rewards Distribution Flow

Rewards are distributed for:

• User registration

• Engagement actions

• Campaigns and promotions

• Gamified features (e.g. spinners, quests)

Flow

Rewards Contract → User Wallet

Important

• Rewards are minted or allocated according to predefined rules

• Distribution logic is deterministic

• Rewards never pass through operator wallets

Users can immediately verify reward transactions on-chain.

4. System-Initiated Transfers (Executor Flow)

Certain flows are executed by authorized system executors.

Examples:

• Settling multi-step games

• Batch reward execution

• Operational transfers between vaults

Flow

Executor → Smart Contract → Target Wallet

Security guarantees

• Executors are whitelisted

• Executors never custody funds

• Contracts enforce destination and amount

• Executors cannot redirect funds

This prevents operator abuse while enabling high throughput.

5. Treasury ↔ Treasury Transfers (Internal Accounting)

In some cases, funds move between treasuries:

• Product balancing

• Migration between game versions

• System-level reallocation

Flow

Treasury A → Treasury B

Constraints

• Explicit contract calls

• Logged events

• No hidden rebalancing

Every treasury remains independently auditable.

What Never Happens (By Design)

GCoin does not:

• Sit in off-chain databases

• Move without a transaction

• Get “credited” without transfer

• Exist as IOUs or shadow balances

• Get settled later

When user sees a balance change there is a transaction hash behind it.

Observability & Auditability

Every GCoin movement can be:

• Traced by wallet

• Grouped by treasury

• Replayed via event logs

• Verified via transaction receipts

This enables:

• Independent audits

• Partner verification

• User trust

• Real-time monitoring

Why This Model Works

The GCoin flow model prioritizes:

• Determinism over convenience

• Transparency over abstraction

• On-chain truth over internal accounting

This keeps the ecosystem:

• Secure

• Scalable

• Regulator-friendly

• Partner-ready

GCoin is not just a token; it is the settlement layer of PlayBlock.
