Smart Contract / Policy Script
On Ethereum, smart contracts life on the blockchain as code that performs specific action. This is not how Cardano smart contracts work. It is helpful to think of smart contracts on Cardano as validator scripts. When a smart contract is written, it is turned into a policy script file, containing a hash that represents the code. The contact was full of parameters that legitimize a transaction. So, when a policy script is attached to a transaction on Cardano, it will only go through if all the conditions of the transaction meet the criteria of the smart contract. Therefore, more complicated functions can be performed on Cardano, because there are policy scripts that are regulating the legitimacy of these transactions.

Consensus Type
The invention of bitcoin brought forth the greatest use case of proof of work. A system that required hardware to use electricity to solve cryptography in order to validate a block on the blockchain. In concern for the environmental demand of energy consumption in this manner, many blockchains thereafter adopted a proof of stake system. Rather than requiring energy to validate blocks, Cardano uses the proof of stake (POS) systems require the ownership of the blockchains cryptocurrency to validate blocks. In this case, rather than the more energy you use being correlated to greater blockchain validation rewards, the more money you have correlates to greater blockchain validation rewards (in this case, knows as staking rewards).
