Data Flow Principles

1. Blockchain as Single Source of Truth:

   • All consensus data resides on-chain
   • Database serves as performance cache with TTL
   • Periodic synchronization ensures consistency
   • Blockchain resolution for conflicts

2. Read Operations:

   Frontend -> REST API -> Cache -> BSC Node

   • All data access through REST API layer
   • Redis cache with 30-60s TTL for performance
   • Background polling updates cache from blockchain
   • SWR/React Query for efficient frontend fetching

3. Write Operations:

   Frontend -> API -> Smart Contract Transaction -> Blockchain
                |             |
                |             +---> Transaction Receipt
                |
                +---> Optimistic UI Update + Database Cache

   • All predictions/commitments routed through backend
   • Blockchain transactions (immediate for staked, batched for casual)
   • Optimistic updates for responsive UI feedback
   • Scheduled sync ensures database consistency with blockchain

Smart Contract Architecture

+---------------------+
|                     |
|  Factory Contract   |
|                     |
+----------+----------+
           |
           | deploys
           v
+---------------------+
|                     |
| Implementation Base |
|                     |
+----------+----------+
           |
           | cloned by
           v
+---------------------+     +---------------------+
|                     |     |                     |
|  Minimal Proxy #1   |     |  Minimal Proxy #2   | ...
|                     |     |                     |
+---------------------+     +---------------------+

Gas Optimization:

• Factory deploys inexpensive EIP-1167 minimal proxies (~45k gas) instead of full contracts
• Each market is a separate minimal proxy pointing to the same implementation
• Implementation contains all logic but no state
• 85-90% gas savings compared to traditional deployment models

Batch Processing System

To minimize blockchain transaction costs for non-staked predictions:

+------------------+     +------------------+     +------------------+
|                  |     |                  |     |                  |
| Accumulate user  |---->| Group by market  |---->|  Create batch    |
|  predictions     |     |    & time        |     |  transactions    |
|                  |     |                  |     |                  |
+------------------+     +------------------+     +------------------+

Batch Parameters:

• Frequency: Every 5-10 minutes (configurable)
• Size: Up to 100 predictions per batch
• Trigger: Time-based OR size threshold
• Cost reduction: ~95% compared to individual transactions

Authentication & Wallet Integration

+---------------------+     +---------------------+
|                     |     |                     |
|    User Session     |---->|  Backend Auth API   |
|    (JWT Tokens)     |     |                     |
+---------------------+     +---------+-----------+
                                      |
                                      | validates
                                      v
+---------------------+     +---------------------+
|                     |     |                     |
|  Smart Wallet       |---->| Blockchain Address  |
| (Account Abstraction)     | (Transaction signing)
+---------------------+     +---------------------+

This architecture enables:

• Standard JWT authentication for casual users
• Web3 wallet signatures for staked predictions
• Smart contract wallets for non-crypto users
• Transparent signing of blockchain transactions
