The given solution is an innovative blockchain-based tool empowering audits on data integrity in public blockchains. Although the current public blockchains claim to provide tamper-proof authenticity of digitised data, the steps to verify this authenticity are long and cumbersome. Making the verification step intuitive and seamless is essential for extending the data authenticity guarantee to a broad spectrum of applications.

In order to perform an audit to verify the claimed authenticity of blockchained data today, one needs to first understand the nuances with the particular blockchain and then apply a sequence of tools for tasks such as hashing, base64 encoding, diff checks, etc. while copying data across these tools. When performed manually, this is a heavily time-consuming and an error-prone task. AuditReel turns this experience into one that is faster and accurate by many degrees by automating the whole audit process. The process which would otherwise deemed to be a super boring job is transformed by AuditReel into a movie-like experience, leaving the auditor with complete autonomy. We believe that this tool will enable us to achieve the data authenticity that blockchain technology has long promised.

Our team has been working on this for the past 7 years under the Tracified project (https://tracified.com) with a focus on supply chain data. The use case was proving the authenticity of product history data to downstream players in supply chains such as end consumers, importers, etc. We got the first version of this tested with many supply chains, covering domains such as agriculture, fashion and gems on Stellar. This version was developed entirely using managed data transactions in Stellar. Under Tracified we called this tool "Proofbot". We intend to generalise it to cover use cases beyond supply chains under the new name AuditReel. Our request for Stellar Community Fund is to finance the development of this generalised version in Soroban on Stellar blockchain. While we'll do this first with Stellar, we plan to later extend it to other popular public blockchains too.

With AuditReel the data contributors will have an app which will automatically geo-code, timestamp and send data directly to the blockchain. Another web app will be developed to conduct the audits. This app will divide each data proof into a sequence of logical steps. Each step will be further divided into tasks such as calling an API, reading data from a JSON, hashing data, etc. For each task the app will load a widely used open source tool within an iframe. Feeding data to these tools and transferring their output to the next step will be done automatically in a transparent way. The entire proof will be presented with a playback interface with options such as play, pause and stop. The auditor will be able to jump to any specific part of the proof and play that part to scrutinise. It will our new JSON based protocol to execute the steps in a proof in a generic fashion.

Proofs will be enabled for complex workflows. These workflows usually represent sequential additions of data pertaining to a physical or digital entity such as tracking data for a product, actions related to the workflow of a digital document in an enterprise or the events in a summer holiday. Workflow divergence (splitting of one workflow into multiple) and convergence (merging multiple workflows into one) will also be supported.

Based on our experience with supply chain use cases so far we plan to support 3 types of proofs in AuditReel, which taken together, we believe will serve the majority of data authenticity proof requirements in the general context. 

1. Proof of Existence (PoE)

This proof guarantees that a particular piece of data has not been tampered after being sent to the blockchain. Together with this basic proof we also bundle the authenticity of the data contributor (via digital signatures), location where the data was provided and the timestamp. 

2. Proof of Backlink (PoBL)

This is a proof on the link between one piece of data in a workflow to the previous one. This proof will also carry information about the change of custody of the entity related to the workflow (when that makes sense for the use case).

3. Proof of Continuity (PoC)

This is the proof of the entire chain (graph, more accurately) of data in a workflow. In a supply chain, it represents the history of a product starting from its origin down to the consumer. As this history may contain an arbitrary number of convergences (merge) and divergences (split), it will be visualised in the web app as a directed graph of nodes. A PoC comprises PoE's for all its nodes and PoBL's between each consecutive pair of nodes.

AuditReel will be a tool embeddable within other apps. It will be coupled with an SDK for this purpose.

How the solution exactly works:

1. Data input and Decentralized Storage
   1. Users utilise the mobile / web app to seamlessly input data at various stages of the workflow
   2. Here the entered data will be called a DP (Data Packet).
   3. The DP will be geo-coded, timestamped and digitally signed
   4. The DP will be encrypted and will be uploaded to IPFS.
   5. Also the DP will be hashed and the hash will be uploaded to the Stellar blockchain together with the cid from IPFS.
   6. SDK will make available the URLs to associated proofs.
2. Auditing PoE and PoBL
   1. The application developer avails the URL to the intended proof in his app UI.
   2. Once the user visits the URL, the auditor web app will be opened.
   3. The user gets a UI containing all components required to conduct an automated audit to the fine-grained levels of detail.
3. Auditing PoC
   1. When a user fires up a URL corresponding to a PoC, a UI will be shown with a graph view where each node represents a piece of data in the workflow.
   2. The user can click on a node to be navigated to the PoE for that piece of data
   3. The user can click on an arrow connecting two nodes (the graph is a directed graph) to be navigated to the corresponding PoBL.
   4. Other metadata related to the workflow will also be shown in the UI.

 

We are presenting the current Proofbot solution with POE as the minimum viable product. Please note that this does not include any implementation related to Soroban currently, the current implementation is on Stellar SDK. You can see a PoE being executed in Stellar mainnet with the current version of Proofbot in the following URL. Once the app is loaded, click the play button and the proof will be played automatically. Use the payback buttons to control the play. In order to jump to a specific part of the proof, click on any of the boxes shown in the "Current Process" pane.

How Soroban will be used in the AuditReel:

1. The smart contracts will hash the DP details
2. The smart contracts will handle the backlink complexities

This will make sure that the app serves a wide range of use cases including scenarios that involve sites with poor internet connectivity. All data will be geo-coded and timestamped before being sent to the blockchain. The app will support simple workflows through “stage transfers”, mapped into multi-sig transactions.
