Which type of blockchain is more secure to use ? centralized or decentralized ?
I think decentralized blockchain is more secure because on decentralized blockchain you can install software nodes as the guarantor of the data's safety and validity
Yes and also, the human factor in data corruption is common in centralized systems, thus rendering them vulnerable to error. In other side the decentralized system exclude the human factor altogether as the data entered in the blockchain cannot be changed and is received directly from tethered devices
