Participate on the
NEM NIS1 Blockchain

Supernodes are high-performance blockchain nodes that form the backbone of the NEM NIS1 blockchain network. Accounts with 3,000,000 or more XEM can operate a supernode, either from a local computer or from a cloud-hosted server. Supernodes are required to be up and running 24 hours per day, processing all transactions.

Supernode Requirements

Supernode accounts are required to hold at least 3,000,000 XEM and are tested four (4) times per day on their bandwidth, chain height, chain parts, computing power, version, ping, and responsiveness to make sure that they are performing the highest standards.

Test
Requirement
Notes
Bandwidth
5,000 kbit/s or higher
2MB downloads averaged from 3 nodes.
Chain Height
Chain must be synced
No more than 4 blocks behind the reference NIS.
Chain Part
Upload 50 block sections of the chain accurately
Hashes of the download are compared to the reference chain for accuracy.
Computing Power
Hash at least 2000 Iterations per second
Node is asked to calculate 10,000 iterations of a 32 byte seed. Speed and final accuracy are measured.
Banded Deposit
3,000,000 XEM
Node must be booted with the delegate key of an account with the deposit.
NIS Version
NIS must be up to date
Admins should update nodes in a timely manner.
Ping
200ms response or less
Ping times for every other node are collected and at least one ping time must pass the test.
Responsiveness
Answer 10 consecutive blockchain height requests
The node passes the test if the overall time needed to answer at least 9 requests is at most 1 second.

Explore Supernodes

The NEM NIS1 network has two layers. The supernode layer keeps the system powerful and fast, whilst ensuring that it maintains efficiency and optimum performance. This layered design allows the second layer of wallets and third-party apps to use the entire network without downloading or processing the entire blockchain.

Supernodes have the ability to host non-supernode accounts.
This is called Delegated Harvesting.
