Nell'audio dico che gli smart contract possono essere aggiornati. Non e' possibile, altrimenti le transazioni salterebbero.
Contract code is permanent. There is no way to alter the code of a deployed contract except by destroying it altogether by the SELFDESTRUCT opcode (selfdestruct() in solidity.)
There's four ways, more or less, to cope with this:
Don't. Just have the contract be eternal, no matter what happens.
Use some scheme to work around this limitation.
Create a new contract, and find some way to reconnect to old users/other contracts.
Create temporary contracts.
