초록/요약
The blockchain is decentralized network system that verifies the validity of the transaction through the consensus of the verifiers without trusted third parties. This mechanism ensures transaction integrity disclosing transaction information transparently. Therefore, it is emerging as the core technology of the 4th industrial revolution by improving reliability and efficiency with features of decentralization, ensuring the integrity, and economic cost reduction. However, there are some problems with the growth of the blockchain. The popularly used PoW (Proof of Work) consensus algorithm applied to the public blockchain requires the price to be compensated in order to agree on the validity of the transaction. This has the disadvantage that the system doesn't operate without compensation. Also, the BFT (Byzantine Fault Tolerance) Algorithm using private blockchain has a limited number of acceptable malicious users. In this case, if the users collude with malicious and exceed the limited number, the transaction is rejected. In this paper, we propose a Smart Manager System and RMBC-DBFT (Randomized Mesh Blockchain Diversity of opinion BFT) enables the safe transaction to the problems above. © 2018 IEEE.
