# PoC-Doc-Delivery

This project contains all the functions needed to retrieve the parameters required to perform a proof of concept.

This repository also contains all the data included in the paper and any additional data required in the `PoC_Execution` folder:

- The Ethereum Yellow Paper in PDF format (`paper.pdf`), which is the message to be signed.
- The JavaScript script to generate all the data values needed to perform the PoC (`getDeliveryData.js`).
- The notification data (`idData`) contained in the script, including @A, @B, @SC, tm, and td.
- @A and @B ECC keys in the script.
- The data values presented in the paper in their respective file: `id`, `f(C)`.
- The ECIES output parameters in their respective files: `k`, `IV`, and `HMAC`.
- Additional files, such as the encrypted file (`C.pdf`) and the decrypted file (`decrypted.pdf`).

In addition, this repository contains the `PoC_Transaction_Data` folder which includes several scripts to retrieve the transaction data from the Sepolia testnet.

## Prerequisites

- Node.js >=16

## Installation

1. Go to the `PoC_Execution` folder and run `npm install` to install the required dependencies.
2. In the `PoC_Transaction_Data` folder, run `npm install` to install its dependencies.

## How to Use

1. Move to the `PoC_Execution` folder.
2. Open the `parameters.js` and set up the notification data (`idData`) and the @A, @B ECC keys.
3. Save the changes.
4. Run `node getDeliveryData.js` to execute the script and retrieve the data.

Once the functions of the smart contract have been executed, the transaction data of each function can be recovered by following these steps:

1. Navigate to the `PoC_Transaction_Data` folder.
2. Open `parameter.js` and set the transaction hashes relative to the `accept` and `publish` functions.

There are several scripts to choose from, each displaying different transaction data:

- `functionInputs&Logs.js`: Displays the parsed inputs and logs of the `accept` and `publish` functions.
- `transactionReceipt.js`: Shows the transaction receipts of the `accept` and `publish` functions.
- `transactionReceiptLogs.js`: Shows the transaction receipt logs of the `accept` and `publish` functions.
- `transactionResponse.js`: Displays the transaction response of the `accept` and `publish` functions.

To run a particular script, simply run `node <file.js>`, where `<file.js>` is one of the previous scripts to retrieve the desired transaction data (e.g. `node transactionReceipt.js`).
