4.2 Flexible and Predictable Transaction Cost Management

Transaction costs (Gas) within the network are designed to be flexible and user-friendly. It employs a dynamic, yet per-unit-computation predictable, pricing mechanism. Users can specify a maximum cost ceiling they are willing to pay for their initiated computational tasks, similar to setting a Gas Limit, ensuring task execution does not exceed their budget.

If the allocated computational resources are exhausted before task completion (corresponding to running out of Gas), the transaction is automatically canceled, and the corresponding token fees for the consumed resources are not refunded; these fees are distributed to the nodes that have already worked. This model, similar to how Ethereum handles out-of-gas transactions, ensures fairness and predictability in resource usage. The total rewards generated by these transactions are distributed between the node executing the task and the node responsible for verifying the task's result according to a predetermined ratio, ensuring fair economic compensation for all roles in the network.
