There are various completely different proof of stake schemes, so let’s simply choose one to speak about. I will likely be speaking in regards to the one which was initially primarily based in Peercoin and is now utilized by many different cash. And I will likely be speaking in regards to the newest model of that scheme because it advanced through the time from being very a lot insecure to be little safer, however nonetheless method much less safe than proof of labor.
So the idea of issue stays there. If you happen to mine blocks to quick, issue will increase and also you want extra luck to have the ability to produce subsequent block.
One other essential traits is that the variety of UTXOs doesn’t matter that a lot. It helps you you probably have lots of them, however so as to have the ability to create subsequent block, your probability is proportional to the full sum of the values of these UTXOs. Subsequently 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 identical, assuming we take only one spherical in isolation.
Solely in long run as a result 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.
