## Summary - Essay

We started our session with a Quick Recap of Unifires in the Last Month.
We decided to first tackle the Topic Blockexplorers.
Our first goal was to find a nice way to start a simple comparison.
We came up with dividing a Blockexplorer in diffrent functionalites.
We choose one functionality after another.
We showed each other how each functionality works on each chain.
We made notes and discussed vividly whats going on where and why.
We reshuffled our Notes and gave it some structure.
In the end we wrote a quick summary.

> :information_source: Cardano Smart Contract:
> Smart contracts in Cardano are divided to onchain and offchain parts. The onchain code is normally not stored on chain, but the hash of the code is used to derive the address of the contract. Transactions that wants to spend from the smart contract must provide the actual code for the contract.
