I don't understand about this altcoin XEM. Price is being pumped now but I don't think this is sustainble. Can anyone explain in layman terms what this coin is about?
XEM is a coin, but that is not what this is about. NEM is a 2.0 blockchain solution written from scratch with entirely new code by a talented team of hard working devs, supported by a team of additional marketers and NEM supporters. NEM was launched about 9 months ago and has been traded on 5 exchanges since then.
Here are the bullet points for you.
Code built 100% from ground up (not a fork of any existing project)
Two-tiered architectural platform with focus on security and safety
Test-driven development
Easy to use universal APIs
Innovative Proof-of-Importance algorithm: first reputation based blockchain algorithm
Improvements on different features of POW and POS coins, being more efficient and more environmentally friendly
Nodes need not be expensive machines and run independent of the wallet
One minute average block times
First blockchain with delegated harvesting (secure and safe proxy mining)
Asset creation with NEM Mosaics featuring fixed or editable supplies, descriptions, levies, and transferring rights
Namespaces for management of unique mosaics and domain names on the NEM blockchain
First with localized spam protection
First with Eigentrust++ peer reputation management for Nodes
First editable m-of-n multisig with blockchain based alerts
P2P time syncing of nodes
Encrypted, unencrypted and hex messaging
Small memory footprint, easy to install, and portable client and server
Zero currency inflation (fixed supply, all 8,999,999,999 billion coins released at launch)
Mijin private permissioned ledger sidechains
Geographically distributed multistaged transaction approvals for NEM Sign/Pay
Mobile wallet for both iOS and Android (coming soon, closed beta now)
Here, in my opinion, is the best white paper for any blockchain.
