Why should I use NEM when there is Bitcoin?

Bitcoin is a crypto currency and so are most crypto coins. Some are application specific while some are purely crypto coins. Apart from NEM being another crypto currency, NEM is a solution platform. There is more to offer as a platform. As a crypto currency, it does not require a lot of computing power and energy to run a node. NEM also advocates low entry barrier with Proof of Importance (POI) instead of the traditional ones that require a lot of stakes or computing power to mine. In NEM we call it harvesting. In addition, it also uses another solution, called Eigentrust ++ to validate and sieve out bad actors in the network. As an evolving solution, NEM is setting the stage for better things to come. At the initial stage NEM has this to offer:

  • Apostille, blockchain notarizations that are transferable, updatable, branded and conjointly owned.
  • Luxtag, a blockchain base
  • Landstead
  • DragonFly Fintech
  • First blockchain based multisig solution.
  • An encrypted messaging solution that also allows unencrypted and hex messaging.
  • Harvesting: Once harvesting is started, you don’t need your wallet to stay open to harvest. It can be closed and the wallet does not need to be online.
  • Protected wallet, i.e., wallet does not need to be online. It can hide behind a firewall and only connects itself directly to the NIS via the local network.
  • The wallet is protected by a password. The password and private key never leaves the computer on which the wallet is running.
  • Mosaics are NEM’s asset feature and allows assets to be created to be mutable, immutable, capped, not capped, divisible, not divisible, ability to be bagged with other tokens, and levied. They come with descriptions and are a part of Namespaces.
  • NEM’s naming service, Namespaces, allows organizations to build a brand or brands that can be known and identified helping to increase their projects’ reputation.
  • Mobile wallets for Android and iOS as well as a pure javascript light wallet for desktops.
  • Spam protection designed to prevent attacks on the network by raising the fees of the attackers.

Other common Issues

What is Harvesting?

Harvesting is a process whereby a node will calculate blocks and add them to the blockchain. A block contains all transactions that were sent in the last minute. In other words, a block is calculated every minute. With the help of the proof-of-importance algorithm it is decided which node is allowed to calculate a block and can keep all included transaction fees. More info can be found here.

How can I Harvest?

Requirement: The user account needs a vested balance of at least 10,000 XEM.

What is delegated harvesting?

Delegated harvesting is a security feature in NEM that allows a person to safely harvest using a proxy private key. This proxy private key is created by transferring the POI score of a primary account to an empty delegated account. That private key can now safely be shared with others as it doesn’t actually contain any of the funds in the primary account. This allows a person with delegated harvesting activated to give their private key of the delegated account to third parties so that they can harvest with it. All funds earned from harvesting are then automatically sent back to the primary account. More info can be found here.

How does the vesting of XEM work?

In NEM coins are aged in at 10% per day of the remaining unvested XEM in an account. This is explained in detail in section 2.1 of the NEM Technical Reference.
