 In order to ensure the security of the chain, **minting is also structured based on level in regard to block signing.** Block signing simply means the actual minter that creates and adds the block that ultimately gets utilized by the overall chain. In order to ensure the security of the chain, **minting is also structured based on level in regard to block signing.** Block signing simply means the actual minter that creates and adds the block that ultimately gets utilized by the overall chain.

 === Measuring 'Contribution Over Time' === === Measuring 'Contribution Over Time' ===
  
-Minting is sometimes referred to as **proof of contribution over time (and Memory Proof-of-Work)** and this is a very accurate description. +Minting on Qortal is a method of 'proving contribution over time', as such, the minting algorithm can be referred to as 'PoCoT, or Proof of Contribution over Time. There is also an additional Proof of Work component, accomplished **in-memory** as opposed to raw computational power. The MemPoW is also leveraged differently than most PoW algorithms are. Learn more - [[block_rewards_distribution|]].

-=== The MemPoW (Memory Proof of Work) Algorithm === +
- +
-The **Memory Proof-of-Work (MemPoW)** portion of the above statement, comes from the **MemPoW algorithm** that is also part of Qortal Minting. The MemPoW algorithm is utilized in a different fashion to that of most Proof-of-Work algorithms in other blockchains. Whereas most PoW chains utilize the algorithm with a 'modifiable difficulty' that changes based on how many 'miners' are actively contributing 'hashrate' to the network, Qortal utilizes a **set difficulty** on the MemPoW, and merely uses the algo to **limit the number of minting keys that can be assigned to any given physical computer.**  +
- +
-The **MemPoW algorithm** is a Memory-based Proof-of-Work (PoW) algorithm that is utilized in multiple places within Qortal. In regard to minting, the **MemPoW must be computed, and submitted with each minter signature**. The algorithm is different than other PoW algorithms in multiple ways: +
- +
-  * MemPoW uses a set difficulty for every minter +
-  * MemPoW is computed and submitted with each minter signature +
-  * MemPoW uses a SET amount of RAM (1MB) (instead of providing more hashrate for more hardware like most PoW algorithms.)  +
-  * MemPoW merely limits the number of minting keys that can be assigned to any physical computer, so that those looking to 'cheat' the system by assigning more than 2 minting keys, will have a hard time actually accomplishing this. +
