Is it possible to block some UTXO like PIVX, does is possible in bitcoin? if yes then how and doesn't it reduce supply from total supply of bitcoin?
Let's Assume that account A got 5 bitcoin from Some random account and he spend 2 bitcoin. when he transfer 2 bitcoin he will send 5 btc and receive back 3 BTC as for my understanding. now if i want to make some change in code and block that UTXO of 3 BTC can this be done using code.
Sorry for my poor english.
