What is conditional proof of capacity cpoc for cryptocurrencies?


Conditional proof of capacity is a consensus protocol algorithm that uses in blockchains. It enables mining devices in the network to determine mining rights and verify transactions using their limited hard drive space.

This is in contrast to using the computing ability of the mining rig (as in the proof of work algorithm) or the miner’s cryptocurrency stake (as in the proof of stake algorithm).

CPoC consensus algorithm reduces energy usage and lowers entry barriers in the more decentralized cryptocurrency processing phase without compromising protection.

Key Features

CPoC is both energy-efficient and environmentally sustainable.

Conditional Proof of Capacity (CPoC) authorization schemes store answers to a cryptocurrency hashing problem on a hard drive’s free space.

The key advantage of a CPoC system over proof-of-work (PoW) and proof-of-stake (PoS) systems is its performance.

Explaining Proof of Capacity

The challenge of high energy consumption in proof of work (PoW) systems and cryptocurrency hoarding in proof of stake (PoS) systems led to the creation of Conditioned Proof of Capacity as one of many alternatives.

CPoC operates by saving a list of potential solutions on the mining device’s hard drive. Rather than constantly changing the numbers in the block header and hashing for the solution value as in a PoW system. It happens right before the mining activity begins,

The more potential solution values a miner can store on his hard disc, the more chances he has to fit the requisite hash value. It is done from their list, resulting in a higher risk of winning the mining reward.

What’s the deal?

Plotting and mining are two steps in the proof-of-capacity protocol.

First, the drive does plotting:

A list of all possible nonce quantities, including a miner’s account, generates by repeatedly hashing data.

Many of the hashes are paired into “scoops,” which are groups of two neighboring hashes.

The second stage is the actual mining, which entails calculating a scoop number by a miner.

For each nonce stored on the miner’s hard disc, the procedure repeats to calculate the deadline. The miner chooses the one with the shortest deadline after calculating all of the deadlines.

Until a miner is able to forge a new block, a deadline reflects the time that has passed since the previous block was forged.

The miner will forge a block and demand the block reward if no one else has done so during this time frame.
