NEM is a peer-to-peer cryptocurrency and blockchain platform launched on March 31, The NEM blockchain software is used in a commercial blockchain called Mijin,  which is being tested by financial institutions and private companies in Japan and internationally. The NEM developers are pseudonymous. The goal of the call was to create a community-oriented cryptocurrency from the ground up.
The redemption process to obtain coins at launch was fraught with problems. Hundreds of people who either held the NEMstake asset on the NXT exchange or registered on bitcointalk to receive coins, did not receive them. The coins that were not distributed to the initial stakeholders, were kept by the developers.
The hack only involved NEM. Because the security breach was caused by the lack of strong security measures of Coincheck, the NEM development team refused to conduct a hard fork. Instead NEM is creating an automated tagging system. This automated system will follow the money and tag any account that receives tainted money.
NEM's design architecture consists of two components. The second is the client used for interacting with the nodes. The NCC is client software that includes a wallet. Both NCC and the NanoWallet can be run isolated from the internet, providing security through an airgap.
As of February , maintenance of the open source portions of NEM's core has been sparse. With a short-lived exception of some moderate code revisions made in mid, only minor changes have been made to nem. Within namespaces, there are higher level domains and subdomains. This allows one person with one domain to create many different subdomains for their different projects or outside business accounts.
It also helps to build and maintain a reputation system for Mosaics. In proof-of-work, the amount of work a node does is used as a measure for its ability to protect the network.
This adds to the NEM network's ability to be run and maintained efficiently. A NEM user's importance is determined by how many coins they have and the number of transactions made to and from their wallet. POI uses the NCDawareRank  network centrality measure, the topology of the transaction graph, as well as a number of other relevant signals to achieve consensus.
In proof-of-stake systems a person needs to have large numbers of coins to form a block, but in NEM transactions volume and trust become factors.
To be eligible for entering the importance calculation, an account must have at least 10, vested XEM. All accounts owning more than 10, vested XEM have a non-zero importance score. With a supply of 8,,, XEM, the theoretical maximum number of accounts with non-zero importance is , In practice, the number of actual accounts with non-zero importance is not expected to approach the theoretical max due to inequalities in held XEM and also the temporal costs associated with vesting.
If necessary, this number could be updated in the future via a hard fork, which is the same procedure for adjusting transaction fees and other parameters related to harvesting.
Harvesting is the act of forming blocks. Messages can be included in transactions in either encrypted, unencrypted, or hex messaging forms. This can be used for secure communication to any XEM address, as well as blockchain based applications. The fee for sending unencrypted messages is currently 1 XEM for every 32 characters, while encrypted messages will vary. NEM implements multisig short for multi-signature technology on its platform. This means that m out of a total of n signatories must sign a transaction before it can be broadcast onto the blockchain.
NEM's multisignature works by making a contract on chain so that the "m" accounts have full transaction privileges over the account that has been turned into a multisig account. Since the contract metadata is on chain, it can easily be updated by adding or subtracting additional signers given that the required number of parties agree on it.
Multisignature accounts require that another user or users sign a transaction before it can be broadcast onto the blockchain. This means that if one person loses their wallet through a hack, no money can be spent unless another wallet or wallets if m is more than 2 signs it. Multisignature accounts also help protect community-held funds, in that a majority of designated users must agree before a transaction can be spent from a community-held wallet.
This is especially important considering over a third of all XEM in circulation is held in these community wallets. Mijin is a private blockchain that uses the NEM software.
