# Zcash Proof of Stake Megathread ðŸ§µ

Hey all!

I seem to be groping for a concept that could suit all parties and completely cover the risks that I wrote about earlier. Let me remind you that I am very worried about the behavior of the PoS model in halving, namely the threat of dumping coins due to a decrease in staking profitability in anticipation of a reduction in reward.

So maybe the community is happy with a hybrid model consensus. I propose to consider options when the share of PoS reward will double at the time of halving.
For example, these can be the following distribution models:
2nd halving: 20% PoS - 80% PoW
3rd halving: 40% PoS - 60% PoW
4th halving: 80% Pos - 20% PoW
5th halving: 100% PoS.

Or this option:
2nd halving: 25% PoS - 75% PoW
3rd halving: 50% PoS - 50% PoW
4th halving: 100% PoS

Such a system mitigates the possible negative economics and psychological consequences of the transition. Also, the concept fully gives a long-term understanding for miners and holders in which vector everything moves without abrupt changes in the rules - very smoothly and very balanced with respect to each side of the community. Also, the concept clearly defines long-term environmental priorities.

In addition, if my theory of cost still works, then such a concept actually has an accelerated coefficient of increase in the cost of one coin at the time of halving, instead of a 2-fold, 2.5-fold increase for the first example and 2,6-3-fold increase for the second. I donâ€™t insist on a specific distribution, but I believe that distributions should provide for a two-fold increase in the share of PoS at the time of halving in order to compensate for staking.

My calculations are very simple. At the time of the second halving, the number of coins in circulation will be 15,750,000. Letâ€™s say 10% of all balances will launch their own stacking nodes (1,570,000 coins). Then the reward in the amount of 25% of the issue will be 1800 coins x 25% = 450 coins per day, i.e. 164,250 coins per year. Which gives more than 10.46% per annum to these nodes. Even if we assume that the balances of the nodes will be significantly higher than 10% (which in practice does not occur), then the reward will tend to 1.04% per annum. I think this range is sufficient to motivate node creation, but this is model not be super profitable, in order to depreciate the value of Zcash.

At the same time, each subsequent halving does not reduce the percentage of remuneration, and the 12-16 year time reserve allows us to believe that the percentage of remuneration from commissions will grow along with the adoption of Zcash as a popular means of payment.

Honestly, I am ready to vote for this model today.
