RPC stands for Remote Procedure Call. Think of it like a special direct line to the Solana blockchain. You use this line to ask questions, like checking your balance, or to send messages, like making transactions. ## Why use private RPC Nodes? **Speed and Reliability:** Imagine driving on a busy highway with lots of traffic. Public RPC nodes can be like that—slow and crowded. But a private RPC node is like having your own fast lane on the highway—it’s just for you, so it’s quicker and more reliable. **No limits:** Public nodes often have usage caps, like toll roads with limits on how many times you can use them. Private nodes usually have higher rate limits, so you can use them more heavily without getting throttled. **Location:** With large, public RPC nodes, you have less insight into where the RPC node is located. If you host a Virtual Private Server (VPS) in a specific location, you can find a private RPC node in the same location (even the same datacenter) and have significantly less latency. ## Why Traders Love Them If you’re into trading, speed is everything. With a private RPC node, particularly when your VPS is in the same location, your transactions are lightning-fast, which can make a huge difference in your trading success. Private Solana RPC nodes are like having your own fast, secure, and customizable driving lane to the blockchain. They ensure your transactions are quick, safe, private, and unlimited.
