A Meticulous Breakdown of Polygon ZK Rollup Architecture test

by | Dec 23, 2025

If you’ve been building on Ethereum for any length of time, you’ve probably run into this: your app starts slowing down, or worse, goes completely unresponsive when traffic spikes. Maybe you’re using a shared node RPC services, and just as your dApp starts gaining real traction, you hit a rate limit.
You get frustrated, right? All your efforts of writing smart contracts, polishing the UI, and getting everything just right start seeming meaningless all of a sudden. It’s not easy to cope up with the situation when everything is grinding to a halt and your users are the first to feel it. Their transactions lag. The interface stutters. Things just stop working the way they should. And to them, it doesn’t matter what’s causing it. They only know it’s broken.
What’s really happening behind the scenes? Most developers begin with shared RPC nodes from providers. Honestly, these options are cost-effective, convenient, fast to set up, and perfect for development and testing.
But as your app grows and traffic increases, those same endpoints start showing their limits. Shared infrastructure wasn’t built for production-grade performance. And when it breaks, it breaks the user experience. Relying on an RPC node provider that offers a dedicated RPC endpoint will be a great relief. Instanodes does that efficiently.
The best part? You don’t need to go down a rabbit hole of server configurations and DevOps to fix it. Running your own Ethereum RPC node today is a lot simpler than it used to be. With modern managed providers, you can spin up a dedicated, production-ready node in minutes. No blockchain sync headaches. No maintenance chores. Just stable, reliable infrastructure, ready to scale with your app.

Role of Nodes

Let’s understand what these RPC nodes do, as it will make your setup decisions easier.

Consider nodes to be the clerks of the world of blockchain. When your application wants to figure out someone’s ETH balance, if a transaction was processed, or to invoke a smart contract function, it queries a node. The node searches through its version of the blockchain and responds.

Here’s what your node handles behind the scenes

Storing Everything

Your node maintains a complete copy of the Ethereum blockchain. Every transaction, every smart contract state change, every account balance – it’s all there. This isn’t just historical data either the node constantly updates its records as new blocks get added.

Answering Questions

When your application sends an RPC request, the node handles that request and returns the appropriate information. Whether you are querying whether one has sufficient tokens for a trade or querying transaction information, the node does the work.

Broadcasting Transactions

As users use your app and initiate transactions, your node disseminates those transactions out onto the network so miners (or validators) can find and include them in blocks.

Staying in Sync

The blockchain never ceases to move, and your node runs continuously to keep up with the latest blocks. This syncing procedure keeps your app constantly updated with the latest data.

Handling the Technical Stuff

All those complex networking protocols, data structures, and cryptographic verifications? Your node manages all of that, so your application doesn’t have to.
The beauty of having your own node RPC setup is control. You decide how much data to cache, how fast your responses need to be, and you never have to worry about hitting someone else’s rate limits during critical moments.

What Makes

Ethereum The Popular Choice

I’ve had experience with many different blockchains throughout the years, and each one has its merits, but Ethereum by far beats the rest when it comes to creating serious applications. Here’s why most developers end up settling on Ethereum, even when alternatives appear cheaper or quicker on paper.
