Question 1

Consider the following scenario: A large department store chain is being pressured by lawmakers to
provide evidence that proves the store’s clothing is not produced through child labor. This is no easy
task currently due to the store’s clothing being transferred between at least 6 different parties in
between creation and placement at the storefront. The store chain is considering the use of

Question 4

When writing and considering push and pull in a smart contract that involves "user" funds would it be better to ____________________?

Accepted Answer

B

Explanation: Withdraw funds rather than push funds to them automatically Favor pull over push for external calls as we've seen, external calls can fail for a number of reasons, including external errors. To minimize the damage caused by such failures, it is often better to isolate each external call into its own transaction that can be initiated by the recipient of the call. This is especially relevant for payments, where it is better to let users withdraw funds rather than push funds to them automatically. (This also reduces the chance of problems with the gas limit.)
