I totally agree...Blockchain technology as a decentralized entity is a good solution to handle single point of failure, the Blockchain has a collection of member nodes , even if one fails other will still be operating normally with multiple "nodes”" with the Blockchain acting as a consensus mechanism to ensure those nodes stay in sync... Hence ,Blockchain technology handles extreme fault tolerance, which stems from their built in redundancy. A true revolutionizing technology with immense potential to change the world.
