First OneCoin $ONE - then OC $OC - now OC Protocol $OCP

OCP - OC Protocol The Open Source CryptoCurrency

OneCoin was announced February 22nd and launched March 1st 2017 (unix time 1488326400). There was no premine and the block reward for the first 500 blocks was 0, making the first four days of mining with 0 payout to prevent low difficulty instamine. The project was taken over by the community in the first days, developing additional services like block explorers, mining software and social networks. There is no roadmap for this project. Forking the code and developing new features is encouraged.

This cryptocurrency features a unique reward structure. Paying 0 reward for Proof Of Stake rewards, a PoS block is mined only when a transaction paying the network tx fee is present in the memory pool. Therefore the PoS reward is fees only while the PoW reward is the coinbase transaction plus fees.

The idea behind the reward structure:
- PoW miners get paid by the network for spending energy and securing the network
- PoS miners (stakers) get paid by people using the network (paying transactions fees) in the beginning that is practically zero, but the expenses of running a full node while the network is young is also close to zero (incentive to run a full node grows as the network grows or more accurately, when transaction volume grows)
- Long term competition develops in the fee market between the miners and stakers, pushing the price of fees downwards for the users.
