OpenRTB real-time bidding (RTB) in digital advertising Demand-Side Platforms (DSPs) Supply-Side Platforms (SSPs) In recent years, the adoption of blockchain technology in the advertising space has introduced innovative, decentralized platforms that can benefit from integrating OpenRTB. In this blog post, we will explore how OpenRTB can be used in a crypto-native advertising platform, where bid requests and responses are managed through on-chain smart contracts, referred to as the On-Chain Ad Protocol. Overview of Crypto-Native Advertising Platform A crypto-native advertising platform leverages blockchain technology to facilitate decentralized, transparent, and secure transactions between advertisers, publishers, and users. Key components of a crypto-native advertising platform include: On-Chain Ad Protocol: A set of on-chain smart contracts for handling ad bookings, validation, reward distribution, and proof of completion. Proof of Completion: A mechanism within the On-Chain Ad Protocol that allows users to prove they have completed their engagement or action, triggering automatic attribution or reward distribution. Decentralized Data Management Platforms (DMPs) for user segmentation and targeting. Tokenized ad inventory and rewards. Integration with decentralized identity solutions for privacy-preserving user tracking. Integrating OpenRTB with a Crypto-Native Advertising Platform The integration of OpenRTB with a crypto-native advertising platform requires several key steps, including: Custom OpenRTB Extensions To support the unique aspects of a crypto-native advertising platform, custom extensions can be added to the standard OpenRTB bid request and response objects. These extensions can include information related to tokenized ad inventory, On-Chain Ad Protocol, user segmentation data from decentralized DMPs, and proof of completion mechanisms. These custom fields will be added as extensions using the "ext" field. Bid Request Extension: {
  "id": "12345",
  "imp": [
    {
      "id": "1",
      "banner": {
        "w": 300,
        "h": 250
      },
      "ext": {
        "on_chain_ad_protocol": {
          "user_wallet_address": "0x1234567890abcdef1234567890abcdef12345678",
          "token_type": "ERC20",
          "protocol": "0x9876543210abcdef1234567890abcde987654321",
          "mechanic_id": "MECHA123"
        }
      }
    }
  ],
  ...
} In the bid request, we include the user's wallet address, the token type (e.g., ERC20), and the for which the user is engaging. mechanic_id This information will help the advertiser target the user and link the right ad content to the target mechanic validation. Bid Response Extension: {
  "id": "12345",
  "bidid": "abc123",
  "seatbid": [
    {
      "bid": [
        {
          "id": "1",
          "impid": "1",
          "price": 2.50,
          "ext": {
            "on_chain_ad_protocol": {
              "reward_token_contract_address": "0xabcdef1234567890abcdef1234567890abcdef12",
              "reward_amount": 50,
              "engagement_rules_url": "https://example.com/rules"
            }
          }
        }
      ]
    }
  ],
  ...
} In the bid response, we include the reward token contract address, the reward amount, and a URL containing the rules. This data will be used by the publisher to display the ad to the user and inform them about the rewards they can earn for successful completion. By adding these custom extensions to the OpenRTB bid request and bid response objects, we can effectively integrate the On-Chain Ad Protocol's unique features into the existing OpenRTB framework. This enables seamless interaction between the crypto-native advertising platform and the traditional programmatic advertising ecosystem. Oracle AdServer To bridge the gap between the off-chain OpenRTB ecosystem and the On-Chain Ad Protocol, an AdServer Oracle can be employed. This server-side component is responsible for translating OpenRTB bid requests and responses into on-chain transactions and vice versa. The AdServer Oracle ensures seamless communication between OpenRTB-enabled DSPs/SSPs and the crypto-native advertising platform's On-Chain Ad Protocol. Suppose a publisher wants to display an ad with a quest engagement from the On-Chain Ad Protocol. Here's a step-by-step technical illustration of how the AdServer Oracle comes into play: Publisher sends ad request to AdServer Oracle: When a user visits the publisher's site or app, the publisher sends an ad request to the AdServer Oracle, including the user's session and wallet information: {
  "user_session": "session123",
  "wallet_address": "0x1234567890abcdef1234567890abcdef12345678"
} AdServer Oracle fetches on-chain data: The AdServer Oracle connects to the blockchain and fetches the relevant on-chain data, such as available ad inventory, quest details, and reward token information. This is done by interacting with the On-Chain Ad Protocol's smart contracts. AdServer Oracle communicates with off-chain components: The AdServer Oracle communicates with off-chain components, such as the Demand-Side Platform (DSP), Supply-Side Platform (SSP), and Data Management Platform (DMP), to gather user performance data, segments, and ad inventory. AdServer Oracle prepares the ad manifest: Based on the on-chain and off-chain data, the AdServer Oracle prepares an ad manifest containing the ad content, engagement details, and reward token information: {
  "ad_content": "https://example.com/ad_creative",
  "quest_details": {
    "mechanic_id": "MECHA123",
    "engagement_rules_url": "https://example.com/rules"
  },
  "reward_token": {
    "contract_address": "0xabcdef1234567890abcdef1234567890abcdef12",
    "amount": 50
  }
} AdServer Oracle sends the ad manifest to the publisher: The AdServer Oracle sends the ad manifest to the publisher, which then displays the ad content and the quest engagement to the user. The user can interact with the mechanics, and upon successful completion, the user's wallet will receive the reward tokens as specified in the manifest. By utilizing the AdServer Oracle, the crypto-native advertising platform can efficiently bridge the gap between on-chain and off-chain components, allowing for seamless integration and interaction between the various advertising ecosystem participants. Integrating On-Chain Ad Protocol with OpenRTB The On-Chain Ad Protocol should be designed to handle OpenRTB-compatible bid requests, validation, reward distribution, and proof of completion. By updating the On-Chain Ad Protocol to support OpenRTB-related metrics and analytics, the crypto-native advertising platform can effectively measure and optimize campaign performance in line with industry-standard practices. Let’s focus on the role of the Supply-Side Platform (SSP) and Demand-Side Platform (DSP) in this integration. SSP Integration: The SSP will need to include the On-Chain Ad Protocol-specific information in the bid request, as well as integrate with the AdServe partner SDK to retrieve on-chain ad inventory. When a user visits a publisher's site, the SSP will create a bid request that contains the necessary information about the user, such as their wallet address, token type, the address of the on-chain protocol contract, and . mechanic_id This can be included in the field of the bid request object: ext "ext": {
  "on_chain_ad_protocol": {
    "user_wallet_address": "0x1234567890abcdef1234567890abcdef12345678",
    "token_type": "ERC20",
    "protocol": "0x9876543210abcdef1234567890abcde987654321",
    "mechanic_id": "MECHA123"
  }
} The SSP will then send the bid request to the connected DSPs, which will use this information to determine the best ad content for the user based on the On-Chain Ad Protocol. DSP Integration: The DSP will need to analyze the bid request and decide which ad content is most suitable for the user based on the On-Chain Ad Protocol information provided. It will also need to include the relevant reward and quest information in the bid response. Upon receiving the bid request, the DSP will analyze the user's wallet address, token type, and mechanics to determine the best ad content to serve. It will then create a bid response that includes the necessary information about the reward token contract address, reward amount, and rules URL: "ext": {
  "on_chain_ad_protocol": {
    "reward_token_contract_address": "0xabcdef1234567890abcdef1234567890abcdef12",
    "reward_amount": 50,
    "engagement_rules_url": "https://example.com/rules"
  }
} The DSP will send the bid response back to the SSP, which will then forward it to the publisher for displaying the ad content and engaging the user with the quest mechanism. By integrating the On-Chain Ad Protocol with OpenRTB in this manner, SSPs and DSPs can effectively bridge the gap between the crypto-native advertising platform and the traditional programmatic advertising ecosystem. This enables seamless interactions between the various participants, including publishers, advertisers, and users, while leveraging the unique features of the On-Chain Ad Protocol. Enhanced Publisher Integration Publishers play a crucial role in the success of the crypto-native advertising platform. To fully leverage the platform's innovative features and ensure seamless integration with the ecosystem, publishers need to make several updates and enhancements to their existing infrastructure.
