Hii @heriadi, You have done a great job on explaining the importance of blockchain technology in simple terms. Your post provides a clear understanding of the advantages and disadvantages of using blockchain. I appreciate your emphasis on the decentralized nature of blockchain and the security benefits it provides in financial transactions.

Your explanation of how blockchain works is also well-done, especially the part about the blockchain ledger and verification procedure. It is commendable that you also touched upon uses of blockchain technology outside of monetary systems, such as online voting systems, supply chain management, and decentralized data storage.
