title: Where smart contracts are technically saved in the ETH blockchain?
body: <p>i have a few question about the &quot;location&quot; of the smart contracts.
  I read articles about blockchain and development of smart contracts, but it is still not clear to me where these contracts are saved.So:
  Where they saved?
  Are they saved in the nodes?
  Is there some sort of db where all smart contracts are saved in?</p>
  <p>Thank you in adavance</p>
