In a Proof of Stake (PoS) mining scheme what prevents miners from producing many extra blocks or inflating the foreign money?
There are lots of completely different proof of stake schemes, so let’s simply choose one to speak about. I will probably be speaking concerning the one which was initially based mostly in Peercoin and is now utilized by many different cash. And I will probably be speaking concerning the newest model of that scheme because it advanced through the time from being very a lot insecure to be little safer, however nonetheless approach much less safe than proof of labor.
So the idea of issue stays there. In case you mine blocks to quick, issue will increase and also you want extra luck to have the ability to produce subsequent block.
One other necessary traits is that the variety of UTXOs doesn’t matter that a lot. It helps you in case you have a lot of them, however so as to have the ability to create subsequent block, your probability is proportional to the overall sum of the values of these UTXOs. Due to this fact think about you’ve got one UTXO with 1000 cash and somebody as has 1000 UTXOs with only one coin. Your probability to create subsequent block is similar, assuming we take only one spherical in isolation.
Solely in long run as a consequence of different properties of the algorithm, it’s barely higher to have many UTXOs. It’s because as soon as the UTXO is used to create a block, the brand new outputs of that transaction are forbidden to take part in block creation for a while.
