Query: Blockchain Storage Load Balancing Among DHT Clustered Nodes   In Bitcoin, to independently verify whether new transactions are correct or
not, a type of a node called "Full Node" has to hold the whole of historical
transactions. The transactions are stored in ledger called "Blockchain. "
Blockchain is an append-only data structure. Thus, to operate Full Nodes, the
required storage capacity would grow too large for resource-constrained
devices. Due to the limitation, the existing lightweight node scheme is that a
node relies on other Full Nodes. In this thesis, to reduce storage capacity
with keeping the independence of each node, we propose a storage load balancing
scheme "KARAKASA" using Distributed Hash Table (DHT). In KARAKASA, nodes
distributedly keep the whole blockchain among DHT networked nodes. We evaluated
KARAKASA from the view of storage capacity and independence. As a result, a
node in a cluster does not need to trust other nodes. We concluded that nodes
in a DHT cluster can behave like Full Nodes without holding the whole
blockchain.
