Alkimi X Walrus:

Summary

In this session, the technical aspects of Walrus, SUI, and Alchemy's integration for ad transaction data are explored. Walrus serves as a decentralized storage solution, ensuring data integrity through replication and encryption. SUI blockchain notarizes data for transparency, allowing programmatic access to ad impressions. The system enhances both ad and financial transparency by linking ad transactions to blobs, certified on SUI. Confidential data, including PII, is encrypted and accessible only by authorized parties. The discussion emphasizes the need for efficient data retrieval, scalability, and financial assurance, providing a seamless, transparent solution for advertisers and publishers.

Takeaways

• 😀 **Decentralized Data Security**: Walrus provides decentralized storage, ensuring data replication and security, preventing modifications or loss of critical ad impression data.
• 😀 **Critical Ad Data for Financial Reconciliation**: Ad transaction data is essential for determining financial transactions, such as how much advertisers need to pay publishers and how much goes to Alchemy.
• 😀 **Blobs Store Multiple Ad Transactions**: Ad transaction data is stored in blobs, each containing thousands of transactions, with a clear link to the specific ad impressions they represent.
• 😀 **Blob Size Optimization**: The optimal size of blobs is determined through experimentation to balance write and read efficiencies, ensuring fast retrieval of ad transactions.
• 😀 **Programmatic Access to Data**: Walrus and SUI blockchain integration allow for programmatic retrieval of ad transaction data, enhancing transparency in ad impressions.
• 😀 **Transparency and Auditability**: Every ad impression is traceable from the ad transaction to the blob ID and further to the SUI object ID, providing full transparency in the data chain.
• 😀 **Integration with SUI Blockchain**: Ad transactions are linked to the SUI blockchain, ensuring data integrity through notarization, which can be tracked from impression to financial reconciliation.
• 😀 **Financial Transparency**: By aggregating ad impression data, the system can connect campaigns to publishers and facilitate financial transactions, improving the overall transparency of the ad exchange.
• 😀 **Confidentiality of PII Data**: Sensitive information such as Personally Identifiable Information (PII) is encrypted, ensuring that only authorized users (publishers or advertisers) can decrypt and access the data.
• 😀 **Seal and C Layers for Privacy**: The Seal and C systems built on top of Walrus ensure that certain data, such as financial details, remains accessible only to authorized wallets, maintaining privacy and security for PII data.

Q & A

What is the role of Walrus in Alchemy's ad exchange system?

Walrus acts as a decentralized storage solution for ad transaction data. It ensures the security and integrity of ad impressions by replicating and storing them in 'blobs,' providing the necessary assurance that the data cannot be altered or lost.

Why is data replication important in the context of Alchemy's ad exchange?

Data replication is crucial because it guarantees that ad impression data remains secure, consistent, and accessible across multiple nodes, preventing data tampering and loss. This level of assurance is necessary for financial reconciliation and transparency.

How does the SUI blockchain enhance the transparency of the system?

SUI blockchain ensures the notarization of ad transaction data. Every blob of ad transaction data is linked with an object ID on the SUI blockchain, providing traceability and transparency, allowing stakeholders to verify the data's integrity.

What is the significance of blob sizes in the Walrus storage system?

The blob size is important because it affects both the write and read efficiency of stored data. Optimizing the size ensures that data retrieval is efficient while minimizing costs and ensuring scalability as the system grows.

How does the system handle confidential data, such as PII, in the ad exchange?

To manage confidential data, including Personally Identifiable Information (PII), Alchemy uses Seal, which encrypts sensitive data stored in blobs. Only authorized users can decrypt and access this information, ensuring privacy and compliance.

How do publishers and advertisers interact with the data stored on Walrus?

Publishers and advertisers can access data through the Walrus Scan platform using the blob IDs and SUI object IDs. This allows them to retrieve specific ad transactions, ensuring full transparency and the ability to audit ad impressions and associated financial data.

What are the potential benefits of the programmatic access to ad impression data?

Programmatic access allows stakeholders to retrieve detailed information about each ad impression, creating a new layer of intelligence for financial reconciliation. It improves transparency and provides an auditable record of every ad transaction.

How does the system ensure the accuracy of financial transactions related to ad impressions?

The system links ad impressions to financial transactions by associating blob data with campaign wallets and publisher wallets. This enables the transfer of funds based on verified ad impressions, creating a seamless and accurate process for financial reconciliation.

What is the role of Seal in enhancing the security of the ad exchange system?

Seal provides an additional layer of encryption for sensitive data, ensuring that only authorized users can access and decrypt confidential information, such as financial details or user data. This ensures that private data remains secure while maintaining transparency.

What future features are expected to be explored in upcoming sessions related to Alchemy's ad exchange?

Future sessions will explore features such as validators, further integration with Seal, and the AdFI (Ad Financial Integration) system, which will enhance the financial transparency and security of the ad exchange.
