Question 3

Here are several ways in which new coins in an altcoin can be allocated to users. Which of these require changes to Bitcoin?

Altcoin allocation is “grandfathered” from Bitcoin — every owner of bitcoins becomes the owner of a certain number of altcoins (in a fixed proportion of bitcoins to altcoins)

Bitcoin is used as a “reserve currency” for the altcoin — a unit of the altcoin can be created by putting 1 BTC into escrow; the bitcoin can be released by provably destroying one altcoin unit

A unit of the altcoin is created by provably destroying one bitcoin

All coins in the altcoin are generated through (merge) mining and are allocated to miners
