Traditional block+chain structures need a decentralized-like action, which means they need accounters to validate and process transactions, put them in a block and add to the network. However, as mentioned above, Nerthus system used unit+DAG structures without the concept of block. All units are created and released by users. The validation and confirmation of this system should be undertaken by the new unit which referenced the previous unit. Not like traditional block+chain structures, Nerthus doesn’t need centralized actors like accounters to pack transactions. Thus, by contrast, Nerthus is a more decentralized system.
Traditional block+chain structures require a centralized action—accounters have to pack the transactions into blocks. Thus, the transaction processing capacity is dependent on the following three points: 1. The performance of accounters node machine; 2. The network bandwidth of accounters node; 3. The blocksize. Because of the centralized action, the throughput bottleneck will always exist, no matter it is optimized in any way. As above, the unit+DAG structure of Nerthus system do not need accounters to pack blocks, neither does it has the concept of blocks. Units are created and released by users and validated by other units. Therefore, Nerthus does not have throughput bottleneck.
For traditional block+chain structures, transactions have to be packed before validation. If the block size is not enough, and transaction volume is rather large, some transactions may not be added into the block immediately. But if the block is oversized, blockchain data may rapidly explode. At that time, PCs can’t run full nodes, only a limited number of people can run full nodes, which will result in centralization. It is the core conflict of bitcoin blocksize debate. As mentioned above, Nerthus removed the concept of block, so it will not be in the same dilemma as traditional block+chain structures have.
For traditional block+chain structures, two or more blocks may be simultaneously produced, a fork is here to stay. When a fork happens, traditional blockchains consider the longest chain as the valid one. This kind of mechanism is uncertain, as no one can promise the existence of a concealed longest chain. Through Nerthus witness mechanism, as long as the witness unit released by the witness is validated and confirmed, then it means the finality and no one can deny it.
The transaction units in Nerthus, as long as validated and confirmed by the witness unit released by the witness, it has the finality. The witness blocks launched by the witness can be divided into five levels: emergency, urgent, fast, normal and slow. Users can choose the confirmation speed of transactions based on their needs.
