# Function Transcript

### Overview

**Transcripts** **serve as *****certificates of compute*** — **immutable records** that capture every stage of a task execution. Each transcript offers a transparent and verifiable account of how a computation was performed, providing complete traceability and auditability throughout the process.

This example illustrates a **Function Task Execution Transcript**, where multiple nodes submitted identical outputs.

### Execution Lifecycle Messages

<details>

<summary>root message</summary>

This `root message` is the first entry recorded in the execution transcript. It contains key information such as the **execution ID**, the **timestamp** of when the task requester initiated the execution, and the **hash** representing all the messages contained within the transcript.

</details>

<details>

<summary>task_created</summary>

The `task_created` message is added to the transcript when the Truebit platform receives a new execution request from the task requester. It contains key information such as the **execution ID**, the **original message** sent by the requester (stored in the **message** field), and all data is **signed by the Truebit Verify Hub**.

</details>

<details>

<summary>node_outcome</summary>

The `node_outcome` message is recorded in the transcript each time the Truebit Verify Hub receives a response from a Truebit Verify Node. It includes key information such as the **execution ID**, the **original message** from the node (stored in the **message** field), and all data is **signed by the Truebit Verify Hub**.

</details>

<details>

<summary>solutions_revealed</summary>

The `solutions_revealed` message is recorded in the transcript once either the required number of node responses has been received or the execution time has expired. This message includes key information such as the **execution ID** and all the **solutions provided by the nodes**, presented in an **unencrypted** form so that anyone can review the submitted results. These responses were previously **encoded** to prevent premature solution disclosure while the execution was still in progress.

</details>

<details>

<summary>execution_completed</summary>

The `execution_completed` message is logged into the transcript once the entire execution process has been completed — whether the task was resolved through **node consensus** or required intervention by the **Truebit Control Node** during the **Non-Consensus Resolution Process**.
