About NEM

NEM (New Economy Movement) is a peer-to-peer cryptocurrency and blockchain platform launched in March 2015. Also known as XEM, it is written in Java and JavaScript with 100% original code. NEM aims to provide a straightforward blockchain solution for payments, messaging, asset making and more.

History and Development

NEM was created by an anonymous team with the goal of building a blockchain from scratch with new methods and architectures. The developers wanted to address issues they saw in existing blockchains like Bitcoin and Nxt.

The NEM mainnet launched on March 31, 2015 after extensive testing. The genesis block was mined containing 9 million XEM coins, with another 1 million XEM created later. In 2016, the Foundation was established in Singapore to promote the cryptocurrency globally.

The NEM software has gone through several updates and hard forks over the years. Catapult launched in 2019 as NEM’s next-gen blockchain engine, introducing new features like aggregated transactions and multi-level multisignature accounts. The Symbol blockchain also emerged from Catapult, further optimizing NEM’s original design.

How NEM Works

NEM operates using innovative algorithms and consensus methods different from other major blockchains.


NEM uses a Proof-of-Importance (PoI) algorithm to achieve distributed consensus. This was designed to encourage users who actively contribute to the NEM ecosystem.

PoI calculates an importance score based on the number of coins a user holds and how many transactions they make. Users need at least 10,000 XEM vested to be eligible for harvesting rewards. The more XEM someone holds and transacts, the higher their importance and earning potential.


On NEM, mining is known as harvesting. When a block is completed, the harvesting node responsible is rewarded with new XEM.

Successful harvesters need to run a full node and have the minimum 10,000 vested XEM. Higher importance scores increase your chance of harvesting a block and receiving its transaction fees.

Multi-Signature Accounts

NEM allows the creation of multi-signature (multisig) accounts, where an account is tied to multiple private keys. This enhances security for applications, as transactions require signatures from multiple parties before execution.

Multisig accounts on NEM need a minimum of 1 and maximum of 32 co-signers. Account owners can establish customized terms, like requiring 3 out of 5 cosigners for withdrawal. These features make NEM convenient for joint accounts and vaults.

Unique Features

Beyond its distinct consensus approach, NEM has other key features that set it apart.

Customizable Assets

NEM has a built-in system for creating customized digital assets representing anything tradable. Users can define unique assets with customized properties, opening up many uses beyond just payments.

P2P Transactions

NEM offers direct peer-to-peer transactions between XEM accounts. This allows secure transfers without intermediaries in seconds, with negligible fees.

Eigentrust++ Reputation System

NEM plans to integrate an advanced reputation system called Eigentrust++. This will enable users to rate each other, establishing trustworthiness within the network. Businesses can then use ratings as part of risk analysis.

Use Cases

NEM is designed to be versatile for a variety of functions, including:


Like other cryptos, NEM can provide fast and inexpensive peer-to-peer money transfers and payments worldwide.

Supply Chain Management

NEM makes it easy to create digital representations of physical assets, enabling better tracking and transparency in supply chains.


NEM’s multi-signature accounts offer extra security and accountability for electronic voting systems.


NEM’s encrypted peer-to-peer messages and customizable assets enable communication applications with additional functionality.

Adoption and Partnerships

The NEM blockchain is being tested and implemented for real-world use across industries. In Japan, NEM is partnering with financial services firm SBI Holdings to develop shared blockchain services. Startups are using NEM for ICOs and building DApps on the platform.

NEM’s customizable assets have proven valuable for representing tokenized commodities. AXRP Labs uses NEM for its AXRP token backed by precious metal assets.

Criticisms and Challenges

Like any blockchain project, NEM faces challenges to mainstream adoption. Some argue its algorithms and codebase are too complex for most software developers. Others say alternative blockchains have more corporate partnerships traction so far.

Critics have also pointed to instances of turmoil within NEM’s foundation and development teams stalling progress. Ongoing funding and leadership changes have slowed community growth.

Future Outlook

NEM has ambitious plans moving forward, like integrating its advanced Catapult engine to enable scalable smart contract capabilities. The upcoming Symbol platform also aims to help NEM better compete with faster blockchains.

If NEM can bolster its developer community and showcase large-scale applications, it has potential to gain ground in enterprise blockchain adoption. But it still has work to do building supporter mindshare and simplifying onboarding compared to alternatives like Ethereum.

NEM offers a unique blockchain protocol with innovations like Proof-of-Importance and customizable asset creation. Its versatile feature set supports a variety of applications from payments to supply chains. While industry adoption is in early stages, NEM’s focus on ease-of-use provides a strong foundation for the project to capture market share going forward. Real-world use cases and protocol improvements will determine if NEM can reach mainstream success.


NEM (New Economy Movement) is a blockchain platform that introduces several advancements to the blockchain technology space, including its unique proof-of-importance (POI) algorithm, multisignature accounts, and encrypted messaging. It focuses on providing solutions for business applications, emphasizing versatility, security, and ease of use.

NEM was founded by a Bitcoin Talk forum user known as UtopianFuture in March 2015. It was inspired by Nxt, another blockchain platform, and was aimed at developing a more flexible and scalable blockchain technology.

NEM operates using a unique consensus mechanism called Proof-of-Importance (POI). Unlike Proof-of-Work (PoW) or Proof-of-Stake (PoS), POI considers several factors to allocate mining opportunities, such as the amount of XEM held, the number of transactions, and the trustworthiness of the network participants. This approach is designed to encourage active participation and discourage hoarding of the currency.

NEM is used for a variety of applications in business environments, such as asset management, supply chain logistics, notarizations, and ICOs. Its blockchain technology is designed to integrate seamlessly with existing business platforms and processes, offering solutions like smart assets and a robust set of APIs.

NEM (XEM) can be purchased on various cryptocurrency exchanges. Popular choices include Binance, Bitfinex, and Kraken. It’s important to choose a reputable exchange and consider factors such as fees, security measures, and user interface before making a purchase.

NEM (XEM) can be stored in various types of wallets, including:

  • Official NEM Wallet: Available for desktop and mobile, offering direct interaction with the NEM ecosystem.
  • Hardware Wallets: Such as Ledger Nano S or Trezor, providing high security for stored assets.
  • IronWallet: A non-custodial cryptocurrency wallet, prioritizing security and user control over their digital assets.
  • Third-party Wallets: Such as Exodus or Atomic Wallet, offering a balance of accessibility and security.

NEM distinguishes itself with its Proof-of-Importance algorithm, which is a more egalitarian approach to blockchain consensus. Additionally, its smart asset system, which allows users to create custom assets and define their properties, and the easy-to-use APIs for seamless integration with existing systems, set NEM apart from other blockchain platforms.

NEM does not use traditional mining as seen in Bitcoin. Instead, it uses the Proof-of-Importance algorithm, where users ‘harvest’ rather than mine. To participate in harvesting, a user must hold a certain minimum amount of XEM in their account, and their ‘importance’ to the network is calculated based on several factors, including the number of coins held, the amount of transactions made, and the net transfer amount. This method is more energy-efficient compared to traditional mining.
