In the era of AI, machine learning models like OpenAI's ChatGPT have endless applications. ChatGPT provides human-like responses to queries and can be extended with . plugins This article outlines my journey developing a ChatGPT plugin that provides real-time blockchain data from the Ergo Node API. The goal is to equip ChatGPT with the ability to answer user queries related to data on the Ergo blockchain. The Ergo Node API offers many possibilities for ChatGPT plugins, making it an appealing technology to experiment with. By integrating AI technology into the Ergo ecosystem, we can establish a seamless interface between the blockchain data and users. This article discusses an experimental integration of ChatGPT and Ergo, with the aim of enhancing the Ergo ecosystem and providing a more interactive experience for users. Follow along to learn about my experiences and findings. ChatGPT Plugins: A Brief Overview Before we dive into the process of developing the plugin, it's crucial to understand what ChatGPT plugins are and their potential. What are ChatGPT Plugins? ChatGPT Plugins are a new feature introduced by OpenAI to extend ChatGPT's capabilities by interacting with third-party applications. These plugins enable ChatGPT to interface with APIs defined by developers (such as Ergo Node API), which enhances the model's abilities to perform a broad variety of tasks. With plugins, ChatGPT can fetch real-time data such as blockchain node stats, block information, transactions, address balances etc. Developers interested in creating plugins need to expose one or more API endpoints, along with a standardized manifest file and an OpenAPI specification. This design allows ChatGPT to understand the functionality of the plugin and make appropriate API calls. For example, if a user asks about sync status of a node or the balance of an address, the model could call Ergo Node plugin API to generate a response. Developers can register their plugins in the ChatGPT UI. For users to utilize a plugin, they must manually activate it in the ChatGPT UI. Why ChatGPT Plugins? ChatGPT plugins that can access blockchain data could bring significant value to blockchain users for several reasons: Real-time Blockchain Information: Blockchain users often need to track real-time information such as the status of transactions, balances of wallets, or the latest blocks mined. A ChatGPT plugin connected to blockchain APIs can retrieve this information and present it in an understandable manner. Simplified Blockchain Interactions: Interacting with blockchain data often involves complex commands and a technical understanding of blockchain concepts. A ChatGPT plugin could act as an intelligent intermediary, simplifying these interactions by enabling users to request information or perform actions using natural language. Education and Guidance: A ChatGPT plugin could serve as a learning tool, providing explanations of complex blockchain concepts and guiding users in their blockchain interactions. By integrating blockchain data into conversational AI, ChatGPT plugins could make the blockchain more accessible to a broader user base. From Blockchain to AI: Example Requests and Responses In this section, we will explore how the ChatGPT plugin interacts with Ergo's blockchain through the Ergo Node API. We will examine some example requests and responses. The requests are made to a local node (localhost) using only public endpoints, so authentication is not required. The plugin is named "Ergo Node Plugin (no auth)". Note that the plugin accesses real-time blockchain data at the time of writing this article, and most of it may change over time. We start with some questions about ergo node, for example we can ask about version of software. Nodes, can be configured to do mining. Operation of Ergo blockchain can be tuned by miners changing key parameters. We can ask the plugin to retrieve their current values. In case we don’t know the meaning of some parameter, we can just ask in the chat. The plugin uses endpoints from OpenAPI specification configured in the plugin manifest. We can refer to a particular endpoint in the request. And we can also ask to clarify the source of the data in the response. At any time we can ask to perform a fresh request. We can ask questions about any parameter from the response. /info The plugin understands the context and can use any described API endpoint to service the request. And we can also ask it to show the output in a table. This request uses special endpoint. /peers/connected Next, because the plugin knows the specification of the endpoints, besides making requests it can also write a code to make those requests. If we give it an address we can ask for a balance information As we can see, it can also show available tokens (aka assets). What’s more, we can even ask it to show assets information. Last but not least, we can always inquire about the Ergo Node endpoints that the plugin has access to. These endpoints provide the operations that the plugin can use to answer questions. Getting Started with Ergo Node Plugin The Ergo Node Plugin (at the time of this writing) is not available at OpenAI’s Plugin Store. In order to use it you need to run Ergo Node  locally and then register the plugin in the ChatGPT UI. Follow the following steps: Clone Ergo Node source code with the version supporting Ergo Node Plugin (currently in a separate branch). git clone git@github.com:ergoplatform/ergo.git ergo
cd ergo
git checkout -b ai-plugin the jar file Assemble sbt assembly This command will produce a new jar file in the directory. target/scala-2.12/ Setup and run Ergo node using the assembled jar file following the . Make  sure node API is available at (if you’ve configured a different port, use it here as well) instructions http://localhost:9053 Register your plugin in the starting from the step 2 of the . ChatGPT UI instruction Try examples above Under the Hood: Implementation Details Developing a ChatGPT plugin that effectively communicates with a blockchain API is no small task. Here, we'll delve into the details of the developed proof-of-concept prototype. Understanding the Ergo Node API The Ergo Node API is a powerful tool that allows developers to interact with the Ergo blockchain. The API is built on top of the Ergo node, which is a full node implementation of the Ergo protocol. One of the key characteristics of the Ergo Node API is its flexibility. It provides a wide range of functionality, from basic blockchain queries to more complex operations like creating and signing transactions. This makes it a valuable tool for developers who want to build applications on top of the Ergo platform. Another important characteristic of the Ergo Node API is its security. The API is designed to be used by trusted applications, which means that it requires authentication and authorization to access sensitive data. This helps to prevent unauthorized access to the blockchain and ensures that only trusted applications can interact with it. However, the current version of the Ergo Node Plugin only supports endpoints that do not require authentication, moreover only public (”no auth”) endpoints has been exposed to the plugin. get Developing the Plugin The development process and step-by-step guide is describe in OpenAI developer . Here is what has been done in Ergo Node to implement interaction with ChatGPT UI (see details in the ): documentation corresponding PR A simplified OpenAPI  ( file) added with a small subset of API endpoint specifications (see the next section for discussion of why a separate specification is necessary) openapi-ai.yaml plugin manifest configuration is added to .well-known/ai-plugin.json special Routes implemented which are requested by ChatGPT UI: [ - to get manifest http://localhost:9053](http://localhost:9053)/.well-known/ai-plugin.json [ - to get specification of API endpoints http://localhost:9053](http://localhost:9053)/openapi.yaml Additional Routes implemented for new endpoints which was added in openapi-ai.yaml get Additional response headers configured for ErgoHttpService (CorsHandler used by Ergo node) With these changes Ergo Node is able to interact with ChatGPT UI and provide it with the actual blockchain data. Overcoming Challenges: Navigating the Complexities of API Endpoint Design When working with API endpoints, it's essential to realize that not all of them are equally suited for integration with ChatGPT plugins. In this section, I will share key insights and strategies that guided my endpoint design process. My initial plan was to expose the entirety of the Ergo Node API to ChatGPT. However, this strategy proved unfeasible due to the context memory limitations of the GPT-4 language model I was using. Simply put, the Ergo Node API was too extensive, leading to an overflow of the context memory. Consequently, in line with recommendations provided by OpenAI, I significantly streamlined the number of endpoints made available to the plugin. This step ensured that the context memory was used efficiently, thereby preventing an overload. In addition to minimizing the number of endpoints, it was critical to refine their descriptions, adhering closely to OpenAI's . This endeavor ensured that the AI model could effectively interpret and utilize the endpoint data. As such, the majority of descriptions were revised to be more specific, clear, and unambiguous. best practices Interestingly, I found that endpoint descriptions optimized for AI also tended to be more comprehensible to human users and vice versa. A vague description proves as challenging for AI to understand as it does for a human, hindering the effective use of the endpoint. Lastly, I encountered challenges with some endpoints, which were ineffective in retrieving the necessary data from the Ergo Node. Fortunately, this issue was resolved by incorporating the corresponding endpoints, which ensured the smooth and effective retrieval of data. post get Looking Into the Future of AI and Blockchain With this blend of Ergo's blockchain and OpenAI's ChatGPT, we find ourselves at the precipice of a new opportunities in the realm of blockchain UX. The potential for future developments in this space is vast, and the scope for evolution and advancement is truly thrilling. Expanding Conversational Scope The current Ergo Node Plugin for ChatGPT enables users to pose queries about blockchain data and receive informative, AI-generated responses. As this technology evolves, we anticipate expanding the conversational scope of the plugin. This could mean developing the capacity for ChatGPT to understand and respond to more complex and nuanced queries, thereby making interactions even more sophisticated and human-like. Real-Time Transaction Facilitation A future direction could be the integration of transactional capabilities into the plugin, thus allowing users to perform real-time transactions directly through ChatGPT. This means users could instruct the AI to carry out blockchain transactions, adding an unprecedented level of convenience and ease of use. Enhanced Security Measures As we move forward, enhancing the security aspects of the plugin will be a priority. This could involve advanced authentication methods for user interactions, as well as sophisticated mechanisms to ensure the integrity and confidentiality of data. Broader API Integration The success of the Ergo Node plugin could pave the way for similar integrations with other blockchain APIs. This would open up a world of opportunities for AI-enhanced interaction with various blockchains, thereby enriching the overall blockchain ecosystem. ChatGPT Plugins for Ergo Ecosystem DApps With the increasing prominence of decentralized applications (DApps) in the Ergo ecosystem, there's a fascinating opportunity to develop specialized ChatGPT plugins for individual DApps. This could provide users with an intuitive, conversational interface for interacting with these applications, simplifying user experience and facilitating deeper engagement. In conclusion The development of the Ergo Node Plugin for ChatGPT is an interesting and promising step forward in the Ergo ecosystem technology space.
