With 3D block chain and everything they working on is live and first cube satellite is launched, no doubt in my mind it will be 3 digit soon.
What's a 3D blockchain? Sounds like some sort of science fiction gimmick like 3D chess. Maybe I should start reading the documentation, because in crypto such gimmicks can be quickly profitable.
They call it both Multi-Dimensional Chain and Three Dimensional Chain.
This is from Nexus website:
As transactions are performed, nodes in the network start verifying them immediately. When they are validated, they are locked by the CPU miners and assigned a weight (L1). This weight and trust increases as more nodes agree that the transaction has happened. As more transactions arrive, the ‘heavier’ transactions require less work and the CPU miners begin on the newer transactions.
After the transactions are validated and locked, the proof-of-stake nodes start to consolidate them into a single hash using their holdings of NXS to provide weight. This locks the transactions with the L2 Trust Lock, which is far more secure than the L1 locks, because all the information has already been verified at this stage.
The GPU miners finalize the addition of the block to the blockchain by hashing the Merkle root hash produced by the L2 Trust Locks.
