We will provide a crypto RPC node with a HTTP endpoint and a websocket endpoint. We are looking for a solution that achieves the desired outcomes below as we are currently developing an MVP. The frontend is not important and will be worked on later, it can be extremely barebones. Our customers must whitelist their IP in our solution before their requests to our crypto RPC node return data from the blockchain Latency is extremely important - we need very low latency on top of our RPC node for authentication There will be multiple RPC server endpoints that need the whitelist IP updated so that customers can use all endpoints in the pool - Authentication needs to be in sync with all endpoints We believe our competitors are using NGINX to rate limit requests per second but are open to different technologies or stacks if you're able to make a case for using a different technology You will be asked to submit a proposal, and if you demonstrate interest / experience, a more detailed document will be sent to you

Hello, Client. Thanks for your job. Your project to implement a secure and efficient authentication system for your crypto RPC node is an intriguing challenge that aligns well with my expertise. I have experience in developing high-performance backend solutions, particularly for blockchain technologies. Understanding the critical importance of latency, I will focus on creating a system that offers very low latency for authentication on top of your RPC node. My approach will involve setting up a secure method for IP whitelisting and ensuring synchronization across multiple RPC server endpoints. While NGINX is a common solution for rate limiting, I am open to exploring and implementing the most suitable technology stack that meets your specific requirements. I am eager to delve into the technicalities of your project and provide a robust solution for your MVP. Looking forward to the possibility of further discussing this project. Best regards, Ioannis

Hello, I understand that you are currently working on an MVP and require low-latency authentication functionality while ensuring IP whitelisting is in sync across multiple RPC server endpoints. I am interested in working on this project and would like to submit my proposal. I propose to develop a custom solution that addresses the requirements of IP whitelisting and low-latency authentication for your crypto RPC node. The solution will be designed to ensure that customer requests are authenticated and synchronized across multiple RPC server endpoints. To fulfill the IP whitelisting requirement, I recommend implementing a middleware component that sits between the client requests and your crypto RPC node. This middleware will handle IP whitelisting and authentication before forwarding the requests to the RPC node. It will enforce the whitelist restriction and ensure that only authenticated requests are passed through. If you believe rate limiting requests per second is necessary to prevent abuse or manage server load, we can incorporate rate limiting mechanisms into the solution. NGINX is a popular choice for rate limiting, but we can explore alternative technologies or stacks based on your specific requirements and scalability needs. Thank you for considering my proposal. I look forward to discussing the project further with you. Best regards

Greetings, I have a very similar setup for my Ethereum node running on my VPS. I needed to have a node I could use without restriction so I set up geth and lighthouse on a VPS, gave it a week to synchronize, then to avoid people abusing my RPC, I set up a nginx reverse proxy with basic HTTP auth and an IP based rate limiter. My setup is far from being as complete as what you need. Since I did not market my nodes for public use, I was happy enough with HTTP basic auth, but for your case, I imagine we would need a slightly more complex reverse proxy that would either generate a specific URL for each client (like ANKR does) or check access using a token in the request headers (like almost everyone else does). I am perfectly capable of building both systems and am ready to discuss any other solution you might have in mind. Please feel free to send me a message if you would like to ask me any question. No strings attached. Sincerely

Dear Client, We specialize in delivering a robust crypto RPC node with HTTP and WebSocket endpoints for your MVP. Our solution prioritizes IP whitelisting, ensuring customer access to blockchain data upon authentication. With a focus on ultra-low latency, we guarantee swift authentication atop the RPC node. Synchronized IP updates across multiple endpoints enable seamless customer utilization. While competitors use NGINX, we're open to alternative rate-limiting technologies and ready to present compelling cases. The front end, though initially minimal, can evolve post-MVP. If interested, we eagerly await the opportunity to submit a comprehensive proposal, showcasing our expertise and tailored approach. Best, Ajay
