If you've been reading about Vara.eth, you've probably come across terms like Router, Mirror, Executors, Middleware, and Sails.
At first, they sound complicated.
But once I looked into what each one actually does, it started making a lot more sense.
Imagine you're using a dApp built on Vara.eth.
The first thing your transaction reaches is the Mirror. Think of it as the front desk. It receives your request and passes it into the Vara.eth network.
Next, the Executors take over. These are validator-operated nodes that run the program's logic and perform the actual computation. This is where the work gets done.
Once the computation is finished, the Router steps in. It verifies the results, checks validator signatures, and makes sure everything is correctly settled back on Ethereum.
Behind the scenes, Middleware helps coordinate validators, rewards, and network security so everything keeps running smoothly.
And if you're a developer, Sails SDK is the toolkit that makes building and interacting with these programs much easier.
So instead of remembering five technical terms, I like to think of it like this:
Mirror receives.
Executors compute.
Router settles.
Middleware secures.
Sails helps developers build.
Once you see their roles this way, Vara.eth's architecture becomes much easier to understand.
