- Nonce

When a transaction is validated by a miner, it is embedded in a block that is named by a series of random characters, called a Nonce.



- Power Level

Power Level refers to the computational and processing capacity of a blockchain network, usually measured in terms of hash power (hashrate). A high power level indicates a greater ability to secure the network and validate transactions, but it can also require a significant amount of energy.

- Proof of Work (PoW)

Proof of Work (PoW) is the first proof system used in the blockchain. This proof was introduced with the Bitcoin blockchain. It is a consensus algorithm that checks a block by asking the machines, also called miners, to do a very complex job. The objective of this work is to eliminate the potential proliferation of inappropriate information that could affect the proper operation of the blockchain.

- Proof of Stake (PoS)

Proof of Stake (PoS) is a verification process that is completely different from the algorithm Proof of Work (PoW). In fact, there is no question of working on a complex job to validate a new block. Proof of Stake (PoS) based on the principle that it is required to own and stock a certain part of the blockchain, also called staking, to take part in the block validation process. This part is represented by the cryptocurrency of the blockchain.

- PPS (Pay-Per-Share)

It’s a pretty simple method of payment. Miners are paid for each validated share. Then the mining pool will pay a small reward to thank the miners for validating a share. Please note that you will always be paid with the PPS payment method, no matter if the mining pool finds a block or not.

- PPS + (Pay-Per-Share +)

It is an identical payment method similar to regular Pay Per Share. The one and only difference is that the mining pool also pays the fee transactions that are included if a block is found. Fee transactions are a small, but a necessary fee when you make a transaction.

- PPLNS (Pay-Per-Last-N-Share)

The Pay Per Last N Share system rewards miners once a block has been found by the mining pool. You will therefore only be paid after the block has been found. It is important to know that you lose your reward if you disconnect from the mining pool before the block is found.
