Arbitrum Sequencers, their important, and limitations.

What is Arbitrum Technology?

Arbitrum is a set of tech tools that help make Ethereum work better. Ethereum, the blockchain it enhances, has some issues when a lot of people use it at the same time (high network congestion). Normally, Ethereum can only handle about 20–40 transactions per second (TPS), which can make things slow and expensive. But with Arbitrum, this gets fixed using something called Rollup. With Arbitrum, the number of transactions can go up to 14.24–174.52 per second, making it faster and more efficient.

Arbitrum Sequencer:

The Sequencer is like a special leader in the Arbitrum world. It's a particular kind of full node that usually puts users' transactions onto the main Ethereum network (L1). The way it works is by taking all the users' transactions, putting them in order based on when they came in (first come, first served), and then making them happen. The Arbitrum Sequencer is a single, central thing owned and controlled by one group (Arbitrum Foundation) and looked after by Offchain Lab.

Why Arbitrum Sequencer Matters:

The big deal with Arbitrum Sequencer is that it helps make transaction costs lower and reduces crowding on the main Ethereum network by handling transactions away from the mainnet.

Arbitrum Sequencer's Limits:

But, there are some things to keep in mind. The main limit is that the Arbitrum Sequencer has to rely on its own safety measures; it can't get safety directly from layer 1. This means sometimes it might not respond well, or it could act in a way that's not good.
