Blockchain has many advantages other than decentralization. It can make use of blockchain’s intrinsic characteristics like transparency, traceability, immutability, and anonymity. But the application doesn’t need to be in the form of DApp. Let me give you an example. If you realize document notarization service using blockchain, as soon as you save the document for notarization in blockchain, it is not controllable due to the immutability and, it can be utilized as a proof thanks to the traceability. This service can be operated by a centralized startup. As another example, we can think of digital item trading service using NFT (Non-Fungible Token). By using NFT we can prove the original copy of the digital items and making use of this, we can safely trade on the Internet. This uses the blockchain’s immutability, transparency, and traceability. Like this, blockchain has lots of advantages that can be utilized other than decentralization.
