Energy Economy Implementation - Week 1 Progress

What We Built Today

✅ Core Foundation Complete

We’ve implemented the foundation of the energy economy system:

1. Energy Constants (energyConsts.ts)

• Trial credits for new users: 1000 Joules
• Computation costs (hashing, encryption, signing)
• Storage costs (per GB per day)
• Network costs (bandwidth)
• PoW difficulty range (8-24 bits)

2. Operation Types (enumerations/operationType.ts)

• Expanded from 1 to 40+ operation types
• Block operations (store, retrieve, delete, verify)
• CBL operations
• Whitening operations
• Encryption operations
• Quorum operations
• Messaging operations
• Reputation operations
• Network operations

3. Operation Cost (operationCost.ts)

• Tracks computation, storage, network, and PoW costs
• Calculates total Joules
• Utility methods (zero, add)

4. Energy Account (energyAccount.ts)

• Balance tracking (current, earned, spent, reserved)
• Reputation score (0.0 to 1.0)
• Trial credits for new users
• Reserve/release for operations
• Charge/credit for transactions
• Serialization (toDto/fromDto, toJson/fromJson)

5. Energy Account Store (stores/energyAccountStore.ts)

• In-memory storage for accounts
• Get/set/delete operations
• GetOrCreate with automatic trial credits
• Follows existing SimpleStore patterns

6. Energy Ledger (stores/energyLedger.ts)

• Transaction audit trail
• Indexed by member ID
• Time-range queries
• Complete transaction history

7. Tests (energyAccount.spec.ts)

• Account creation with trial credits
• Reserve/release/charge/credit operations
• Reputation updates
• Serialization round-trips
• Store operations

How It Works

New User Flow

// 1. User joins network
const memberId = member.id;

// 2. Create account with trial credits
const account = EnergyAccount.createTrial(memberId);
// account.balance = 1000 Joules
// account.reputation = 0.5 (neutral)

// 3. Store in account store
accountStore.set(account);

Operation Flow

// 1. Calculate operation cost
const cost = new OperationCost(
  0.002,  // computation
  15.0,   // storage
  0.03,   // network
  0.8     // PoW based on reputation
);

// 2. Check if user can afford
if (account.canAfford(cost.totalJoules)) {
  // 3. Reserve energy
  account.reserve(cost.totalJoules);
  
  // 4. Perform operation
  await performOperation();
  
  // 5. Charge energy
  account.charge(cost.totalJoules);
  account.release(cost.totalJoules);
}

Transaction Tracking

// Record transaction in ledger
const tx: EnergyTransaction = {
  id: txChecksum,
  timestamp: new Date(),
  source: userMemberId,
  destination: providerMemberId,
  amount: cost.totalJoules,
  operationType: OperationType.BLOCK_STORE,
  blockId: blockChecksum,
  metadata: {
    dataSize: 1048576,  // 1 MB
    duration: 30,        // 30 days
    redundancy: 3,       // 3 copies
  },
  signature: userSignature,
};

ledger.add(tx);

What’s Next (Week 2)

Storage Contracts

• StorageContract interface
• Contract creation with energy payment
• Expiration tracking
• Link to block storage
• Auto-renewal logic

Integration

• Add energy checks to BlockService
• Charge for block storage
• Credit providers for serving blocks
• Track energy in block metadata

Testing

Run the tests:

npx nx test brightchain-lib --testFile=energyAccount.spec.ts

Expected results:

• ✅ Account creation with trial credits
• ✅ Balance operations (reserve, charge, credit)
• ✅ Reputation updates
• ✅ Serialization
• ✅ Store operations

Key Design Decisions

1. Trial Credits

• New users get 1000 Joules automatically
• Enough for initial exploration
• Prevents barrier to entry
• Can be adjusted based on testing

2. Neutral Reputation

• New users start at 0.5 (neutral)
• Not penalized initially
• Not rewarded initially
• Earn reputation through behavior

3. Reserve/Charge Pattern

• Reserve energy before operation
• Prevents race conditions
• Charge after operation completes
• Release if operation fails

4. Immutable Transaction History

• Ledger is append-only
• Complete audit trail
• Indexed for fast queries
• Supports compliance/debugging

Integration Points

Existing Systems

• ✅ Member system (memberId)
• ✅ Checksum (transaction IDs)
• ✅ Store patterns (SimpleStore, ArrayStore)
• ✅ Serialization (toDto/fromDto)

Future Integration

• ⏳ BlockService (charge for storage)
• ⏳ CBLService (charge for CBL operations)
• ⏳ MessageService (charge for messaging)
• ⏳ QuorumService (charge for quorum ops)

Success Metrics

Week 1 Goals: ✅ COMPLETE

• Energy constants defined
• Account system working
• Transaction tracking working
• Tests passing
• Documentation complete

Week 2 Goals

• Storage contracts implemented
• Integration with BlockService
• End-to-end energy flow working
• Cost calculation service

Notes

This is a minimal viable implementation that:

• Works with existing BrightChain patterns
• Provides foundation for full economic model
• Can be extended incrementally
• Doesn’t break existing functionality

You now have energy tracking! 🎉

Next week, we’ll connect it to actual storage operations and make the economy come alive.
