Nirvana Core:

• Since the launch of the mainnet, the full-node servers have demonstrated excellent computing power. We believe that only full-nodes are needed on the NA chain to support future ecological development. Therefore,we will have a major upgrade, when the block height reaching 5000000, DPoS (CANDIDATE) and DPoS (ACTIVITY) will be cancelled, and all will be merged into DPoS (VOTE). In the future, only full-node devices will be allowed to participate in mining, computing, and storage.
