How smart contracts work in ethereum?
Whenever smart contract transactions occur within the Ethereum blockchain, it takes computational power to validate them across the network. To compensate for the time and energy it takes to perform those computations, transactions require a fee in the form of “gas” which is paid with ETH (define ETH).

Is Smart Contract Code public?
In other words, to achieve confidentiality of the smart contract code, one would have to sacrifice decentralization. Zksnarks allow a verification of a claim done by a party, to another. It works by the both of them sharing a secret. By definition the shared secret cannot be public (or on the BlockChain).
How many smart contracts are there on ethereum?

Are smart contracts stored on the Blockchain?
Smart contracts are lines of code that are stored on a blockchain and automatically execute when predetermined terms and conditions are met. At the most basic level, they are programs that run as they’ve been set up to run by the people who developed them.
How do you test ethereum smart contracts?
To test the internal behaviour of smart contracts we can:Write unit tests to check function return values and state variable values.Write integration tests that test the interactions between contracts. These ensure that mechanisms such as inheritance and dependency injection are functioning as expected.

What does a smart contract look like?
A smart contract is an agreement between two people in the form of computer code. They run on the blockchain, so they are stored on a public database and cannot be changed. The transactions that happen in a smart contract are processed by the blockchain, which means they can be sent automatically without a third party.
How smart contracts are executed?
Smart contracts get executed by the blockchain nodes, as a result of processing transactions that are submitted by the user. A blockchain transaction has a designated target smart contract function, a payload that contains input values to the function call, and always signed by the submitter.
