For me, examples are always very helpful. I feel like I haven't seen that many contract examples...
Lets try to make some basic examples.

I'll start.

A nameserver, where only the sender can edit the data created by that sender:

// input: tx.data[0] = name, tx.data[1] = name data // stores: key: name, value: [owner address, name data] // if the fee isn't large enough to run the contract, stop if tx.value < 100 * block.basefee: stop // if the name can overwrite the contract code, stop if tx.data[0] < 100: stop // if name already exists and the sender isn't the name owner, stop if contract.storage[tx.data[0]]: if contract.storage[tx.data[0]][0] != tx.sender: stop // set name owner and associated data a = array() a[0] = tx.sender a[1] = tx.data[1] contract.storage[tx.data[0]] = a
