|
35 | 8 | - **Centralized State**: `TransactionManager` as the single source of truth for all proposal states |
36 | 9 | - **Optimistic Execution**: Transactions are assumed valid unless challenged |
37 | 10 | - **LLM Integration**: Mock LLM oracle for transaction validation |
38 | 11 | - **Validator Staking**: Delegated Proof-of-Stake with individual validator contracts |
39 | 12 | - **Dispute Resolution**: Economic challenge-response mechanism with slashing |
40 | 13 |
|
| 14 | +All state, validations and challenges resolution will bubble-up to change the state into transaction manager that acts as an input box of transactions. |
