Bitcoin and Cryptocurrency Technologies - Quiz 3 Problem 1

In a typical transaction: (check all that apply)

There is one signature that covers all the inputs	Wrong - there could be more than one
Each input contains a signature	Correct
There is one signature that covers all the outputs	Wrong - output do not need to sign
Each output contains a signature	Wrong - output do not need to sign

This problem is 'tricky'. Every participant who involve in the transaction input must sign the whole transaction - but we never actually sign on the input itself.
