Before introducing POC and Diskcoin, you need to understand POW and BTC first.
Proof Of Work
Ten years ago, Satoshi Nakamoto took the POW into the BTC mining, which once brought more than 200 billion US dollars in economic value to human society. BTC can sit on the throne of the encrypted world, and POW is indispensable. The BTC changed the traditional business model and the role of “miners” was born.
With the development, the miners gradually increased and the competition more fierce. There are large miners, mining pools, mines and other organizations. Due to the emergence of these organizations, the limitations of BTC have gradually emerged. BTC is proud of its decentralization and is no longer decentralized.
At the same time, POW was gradually occupied by ASIC. More and more mining machine manufacturers began to participate in mining. The reward of mining was slowly monopolized by giants such as mining machine manufacturers and mining pools, and small miners lost the opportunity to compete on the same stage.
BTC has been labeled as a privileged label, and now, without enough assets, it is almost impossible to participate in BTC.
Proof Of Capacity
The original intention of Satoshi Nakamoto to design BTC is that everyone can participate in mining and participate in the casting of “currency”. Therefore, in the early BTC mining, only one ordinary computer was needed for calculation work. Now, if you want to use a computer to mine BTC, it is simply a dream. The mining is mainly based on GPU and ASIC mining machines. This makes the cost of mining and the difficulty of mining greatly increase. Most of the hashrate of the BTC full net has been controlled by a few mining pools.
Power energy is also consumed in large quantities. BTC currently has a total hashrate of 43.42EH/S. It is mainly based on the popular S9 ant mining machine currently on the market. The average S9 hashrate is 13TH/S. The converted BTC full net hashrate is equivalent to 3.34 million S9 mining machines! In use, the power of the S9 is 1500 watts, and the power consumption per day is 36 watts. The power consumption of one S9 per month is 1080 watts. If multiplied by 3.34 million machines, the power consumption of the BTC for one year up to 43.2 billion degrees! The BTC full net has consumed more than 159 countries a year, accounting for 0.2% of global electricity consumption!
Can the BTC face a new solution?
At this point, POC boarded the stage of the encrypted world and launched a competition with POW.
Principle of Proof Of Capacity
Before the mining starts, the POC will calculate in advance and the hash value calculated by shabal256 will be stored in the hardisk. This process is called Plotting.
The POC uses a hash algorithm called shabal256. Compared to the B256 sha256, the shabal256 algorithm requires a longer calculation and workload. The benefit of Shabal256 is that miners do not need to perform hash calculations during mining, so the verification process will be relatively fast, and shabal256 will also prevent cheating.
From this, we can know that the energy consumption of POC mining is extremely small. Because the repetitive and large amount of calculations are required compared to the POW, the POC simply scans the stored data.
In order to make everyone understand the POC hard drive mining, I will give you a simple example. POC mining process is similar to the lottery in the hardisk, and the process of mining is that you only need to wait for the lottery to draw the prize, you will scan the lottery in the hardisk to confirm whether it is winning, nothing more.
Someone here may have doubts, will it be faster to use an SSD hard drive? The clear answer is, no. Because the POC only cares the capacity of the hardisk, the larger the capacity is, the more lottery tickets you store on the hardisk, the greater the probability that you win the prize, and this has nothing to do with what kind of hardisk you use, what brand of hardisk.
The POC has changed the traditional mining method, which not only reduces the energy consumption of mining, but also lower the threshold of mining, so that everyone can participate.
Diskcoin
Diskcoin, referred to as DISC. DISC, like Bitcoin, has a total of 21 million. Based on the consensus of hardisk capacity, DISC lowers the participation threshold and allows more participation in the casting of coins, which is more conducive to the realization of decentralization.
DISC uses an upgraded version of the POC algorithm - CPOC Conditioned Proof Of Capacity.
Miners need to Stake Diskcoin to get the most reward. The ratio of Staking is not fixed or gradually reduced. Instead, an algorithmic mechanism called DES (Dynamic Equilibrium Staking) is used to adjust the Staking ratio based on the difficulty of mining. DISC's Staking economy model makes it impossible for miners to sell tokens without restrictions. This initiative is also to maintain the healthy and stable development of the DISC ecosystem.
Supply and demand are very important in economics. Supply and demand are the most direct factors for the decline in commodity prices, and the most effective market feedback. DISC's economic model ensures that the circulation of its currency is stable, keeping it in balance with the number of markets.
CPoC mining combines miners with the entire ecological interests, and replaces the originally consumed power resources with tokens as new production materials, so that the entire ecosystem of DISC continues to expand independently, forming a virtuous cycle system.
