8  Alternate cryptocurrencies / Bounties (Altcoins) / [BOUNTY] MEDICOHEALTH.IO [UP TO 320.000€ IN REWARDS] - COMMUNITY COMPETITION on: March 29, 2018, 09:05:13 AM


The main core of MedicoHealth is to help users get better treatment and health opportunities by connecting them to the best doctors and other healthcare professionals on a decentralized application. In order for us to improve the fragmented healthcare system, and make a significant difference for users, we need to connect with our community and show appreciation to the early supporters. We want to recognize the community effort and give everyone the opportunity to get involved in our project and get fairly rewarded in return. Which is why we have decided to launch a community competition!

We will run several awareness stages of this competition on Bounty0x (register here), rewarding every supporter with MHP tokens. Every few weeks we will release a new stage with different activities.

All stages of the competition will be open and active until the end of our ICO.

The goal of the first stage of our community competition is to spread as much awareness about MedicoHealth project as possible. In this stage we want community to get to know us and our project a bit better.

To build a strong and active community around our project we have decided to team up with Bounty0x and allocate 4,000,000 MHP tokens to our Community Competition Pool.

Bounty0x Campaign Token Breakdown:

Exclusive competition = 5% = 200,000 MHP

LinkedIn = 5% = 200,000 MHP

Healthcare industry is constantly growing in value and complexity.
But unlike other major industries, IT is yet to fully disrupt healthcare.
Decentralized  ledger  technology enables  traceability,  data  immutability  and creation of secure methods for privacy protection,
thus representing a perfect fit for healthcare.

11  Alternate cryptocurrencies / Announcements (Altcoins) / [ANN] [OCP] OC Protocol | NO PREMINE | NO ICO | SHA256 TRIPLE | HYBRID POW/POS on: October 24, 2017, 10:12:41 PM
Here you go folks. New Git org and repo.

Rebranding to pure OCP. Original thread and how it began:

Github code and wallets:
Boostrap files/Chain snapshots:


Ticker: OCP

Block time: 5 minutes

Block reward: 50 OCP with 4 year halving

Maximum supply: 21 million OCP

Proof Of Work algorithm: SHA256T

P2P Port: 8881

RPC Port: 8882

About OCP:

OCP 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.

@KimBasinger ignoring my msg so i guess moving to a new forum thread might be in order. "ups this is the new thread" In case of miracles the old threead will get locked.

How to proceed with your wallet update.

1. Shut down your wallet
2. Go to data dir (see here and look for onecoin dir
3. Linux users rename .onecoin to .ocp
4. Windows users rename Onecoin to OCP
5. OCP conf file with nodes (put it into OCP data dir):

Coin code is intact only cosmetic work was done.

Have fun.
