Neptune Cash Tokenomics Summary

Neptune Cash Tokenomics Summary

  • asymptotical supply limit: 42’000’000 NPT
  • premine: 831’448 NPT, < 2% of the supply limit
  • halvings every 3 years
  • 50% of all block subsidies are time-locked for 3 years; the rest is liquid immediately

Right now, the block time is 9.8 minutes and the block subsidy is 128 NPT. The block time may be reduced in a future hard fork, in which case the block subsidy will be reduced proportionally.

See also Emission schedule for the founders’ thoughts on this issue.

hi aszepieniec, I had thought the blocktime is 60s.

This, Block - Neptune Documentation , indicates a min. block time of 60s. And it seems to indicate a max of 5mins. There is no reference 9.8mins .

The 5 minutes you are referring to is the futuredating limit which says: reject blocks whose time stamps is more than 5 minutes in the future.

Without futuredating limits, you invite the dynamic where miners lie about their timestamp in order to get an easier difficulty later.

The 9.8 minutes comes from the target block interval and isn’t enforced as a minimum or a maximum. Instead, the difficulty is adjusted based on the difference between the concrete block time and the target.

The 3 year lock is the thing that progressively worries me.

I cant stop thinking about this design choice because it feels like serious vulnerability in economic protocol. I just think there is 100% probability that pools collude.

Even at the scale of currently issued and locked NPT this is an mtgox level tragedy.

However, i’ve never heard that someone is working on a less trusted pool which is probably years away.

Сalm me down.

hi master, there is a huge unlock at year 3 or something ?

b) 100% probability that pools collude ? mining pools i guess. And what is the reason tho? Something about that big unlock at year 3 would give them a capacity to collude ?

c) MTgox level tragedy ? how come ?

You’re being quite vague. What’s your perceived problem with the timelocked coins, and how can pool collusion affect the timelock?
