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).
