A Complete Guide to NEM Blockchain

A Complete Guide to NEM Blockchain

What is NEM Blockchain?

NEM is a blockchain platform that was launched in March 2015. Unlike many other blockchain technologies, NEM was not designed to just be a platform for cryptocurrency transactions but rather as a more comprehensive solution for various business needs. It's built to provide an effective platform for managing digital assets and is versatile enough to accommodate a wide range of applications.

Key Features and Concepts of NEM:

Smart Asset System:

At the heart of NEM is its 'Smart Asset System'. In simplest terms, this system allows users to create custom digital assets. These assets can be almost anything - from currencies and tokens to certificates, supply chain items, or even ownership records. The flexibility here is a key strength, making NEM a versatile tool for businesses in different sectors.

Namespace and Mosaics:

NEM introduces two critical concepts - 'Namespaces' and 'Mosaics.' A Namespace is somewhat like a domain name on the internet, providing a way for you to create a unique identity for your assets on the NEM blockchain. Mosaics, on the other hand, are the actual assets. They can be customized extensively – you can define whether they're transferable or divisible, levy fees, and more. This feature provides immense flexibility in asset creation and management.

Proof-of-Importance (POI) Algorithm:

NEM uses a unique consensus mechanism called Proof-of-Importance. Unlike Proof-of-Work (used by Bitcoin), which requires computational power, or Proof-of-Stake (used by many others), which depends on the amount of currency held, POI takes into account several factors. These include the amount of currency you hold, the number of transactions you make, and who you transact with. This system is designed to encourage active participation and discourage hoarding.


In the context of NEM, 'harvesting' is analogous to 'mining' in Bitcoin. However, it's based on the Proof-of-Importance score instead of requiring massive computational power. If your POI score is high enough, you get the opportunity to 'harvest' and earn transaction fees.

Messaging System:

NEM also includes an encrypted messaging system. This allows users to send messages and data securely through the blockchain, adding an additional utility layer to the platform.

Example Use Case:

Imagine a company that wants to issue digital tokens as part of a loyalty program. With NEM, they can create these tokens as Mosaics, configuring them to be non-divisible (since you can't have half a token) and transferable (so customers can send them to each other). They can also set up a Namespace, giving their tokens a unique and recognizable identity. As customers use the service and earn tokens, their interactions contribute to their POI score, potentially allowing them to harvest and earn additional rewards. This creates a self-sustaining ecosystem within the NEM platform.

In summary, NEM blockchain is designed to be more than just a platform for cryptocurrencies. Its unique features, like the Smart Asset System, Namespace and Mosaics, Proof-of-Importance algorithm, and Harvesting, make it an adaptable and efficient solution for a wide range of business applications.

The Importance of NEM Blockchain

The NEM (New Economy Movement) blockchain holds significant importance in the realm of blockchain technology due to its unique features and approach to digital asset management. Its impact and significance can be understood in various contexts:

    Smart Asset System:

    NEM's Smart Asset System is a hallmark feature. It allows users to create custom digital assets or "Mosaics" with relative ease. This flexibility is crucial for businesses and developers who need to tokenize assets, create new cryptocurrencies, or manage data in a blockchain environment.

    Proof-of-Importance (POI) Consensus Mechanism:

    Unlike the more common Proof-of-Work or Proof-of-Stake mechanisms, NEM uses a novel Proof-of-Importance system. This algorithm rewards users for the number of coins they hold, their transaction activity, and the extent to which they support the network. This promotes a more active and engaged network, incentivizing users to participate in the ecosystem beyond just holding the cryptocurrency.


    Harvesting in NEM is an alternative to the traditional mining seen in other blockchains. It's more energy-efficient, as it doesn't require massive computational resources. Users with a high POI score can harvest, thereby earning transaction fees without the need for powerful hardware, making it more accessible and environmentally friendly.

    Ease of Development and Accessibility:

    NEM's API-driven environment means that developers can build applications using NEM with their preferred programming language. This accessibility significantly lowers the barrier to entry for integrating blockchain technology into existing systems.

    Encrypted Messaging:

    NEM includes an encrypted messaging system allowing users to send secure messages through the blockchain. This feature is useful for various applications, from secure communications to complex smart contract functionalities.

    Multisignature Accounts:

    NEM's multi-signature account feature enhances security by requiring multiple parties to agree before transactions can be executed. This is particularly valuable for businesses and organizations that require collective decision-making and added security for asset management.

    Namespace and Mosaic System:

    Similar to internet domain names, the Namespace system provides a unique identity for assets on the blockchain. Combined with the Mosaic system, it allows for creating and managing custom assets with a wide range of attributes, providing great flexibility in asset management.
