Horizen Halving is the event when the number of generated Horizen rewards per block will be halved (divided by 2) from the current 12.5 ZEN to 6.25 ZEN.
Horizen's block reward schedule is close to Bitcoin's in that they have similar halving and emission schedules, Horizen's being faster as each Horizen block takes 2.5 minutes to generate compared to Bitcoin's 10 minutes.
The next halving is set to occur at block # 840,000. Which, depending on the punctuality of block generation, is estimated to happen on 30th November 2020.
Horizen's Block reward is split among 4 entities:
Miners - 60%
Secure Nodes - 10%
Super Nodes - 10%
Treasury - 20%
