Epoch-Based Processing

Understanding Epoch-Based Processing:

The BME module processes mint/burn requests in epochs (batches of ~10 blocks / ~1 minute), not immediately. There is no CLI command to directly view pending operations waiting in the queue.

However, pending operations can be inferred from vault-state:

• Pending mints: When you mint ACT, balances.uakt increases immediately (AKT received by vault), but remint_credits only updates after the epoch completes. The difference indicates pending mints.
• Pending burns: Similar pattern — ACT is received but AKT isn’t released until epoch processes.

To detect pending operations:

# Check vault state
akash query bme vault-state

# If balances.uakt > remint_credits, there are pending mint operations
# The difference = amount of AKT awaiting ACT minting

Tests in this category verify epoch behavior through vault-state and bank balance changes before and after waiting for epoch completion.

Available BME query commands:

• akash query bme params
• akash query bme status
• akash query bme vault-state

Test 4.1: Verify Request Queuing

Objective: Confirm mint requests are processed in epochs, not immediately

User Actions:

1. Record initial vault-state:

   akash query bme vault-state

2. Submit mint-act request:

   akash tx bme mint-act 100000000uakt --from <wallet> -y

3. Immediately query vault-state again (within 10 seconds):

   akash query bme vault-state

   Note: AKT should be in vault (balances.uakt ↑), but remint_credits may not yet be updated

4. Wait for epoch (~1 minute / 10 blocks):

   sleep 60

5. Query vault-state again and bank balance:

   akash query bme vault-state
   akash query bank balances <wallet>

Expected Results:

Key Insight:

• balances.uakt > remint_credits indicates pending operations
• Difference equals the AKT amount awaiting epoch processing
• After epoch: remint_credits catches up to balances.uakt

Proof to Submit:

• Initial vault-state
• Vault-state immediately after mint (showing balances.uakt increased)
• Vault-state after epoch (showing remint_credits caught up)
• User balance showing ACT received

Test 4.2: Multiple Queued Requests

Objective: Verify multiple requests submitted before epoch are all processed

User Actions:

1. Record initial state:

   akash query bme vault-state
   akash query bank balances <wallet>

2. Submit multiple mint-act requests in rapid succession:

   akash tx bme mint-act 50000000uakt --from <wallet> -y
   akash tx bme mint-act 50000000uakt --from <wallet> -y
   akash tx bme mint-act 50000000uakt --from <wallet> -y

3. Wait for epoch processing (~1 minute):

   sleep 60

4. Verify all requests processed:

   akash query bme vault-state
   akash query bank balances <wallet>

Expected Results:

• All AKT transfers to vault complete (150 AKT total)
• After epoch: Total ACT minted reflects all three requests
• User ACT balance = 150 AKT × oracle_price
• Final state is consistent (no lost requests)

Proof to Submit:

• Initial vault-state and user balance
• All three mint tx hashes
• Final vault-state and user balance (showing all 150 AKT processed)
