That's not even correct. The DB Filler doesn't read the blockchain and extract the data fully, only partially. If the DB Filler fails, there's a gap in the transactions. It won't pull all the data. For example, if you delete the database of the DB Filler and restart it, it will start from the moment it's turned back on, old data won't be pulled from the blockchain anymore. Try it out. You haven't noticed this after 20 projects? You also didn't notice that invalid blocks are temporarily added? Because all blocks are added in real-time without being checked first? And then later marked as valid or invalid, but counted in the overall score up to pruning points? You haven't noticed this? And no, this has nothing to do with the chain. It's truly amazing what you haven't noticed after 20 projects, such simple things.
But I do find it really cool that you created a new account for this, the third one. It's also a bit scary at times. Did you forget your old passwords or develop another personality? And don't you have anything better to do if you're involved so professionally in 20 projects?
