Is there an existing issue for this?

I have searched the existing issues

Current behaviour

Hello, Big noob here. I appreciate you taking the time to read this. I have tried scouring the internet including Github for issues similar to what I am experiencing while Syncing The blockchain on my Host Machine. This is not my first time syncing Core to my Pc, but it is the first time I’m experiencing an issue. The same issue arises both on my Linux OS (same machine) and on my Windows OS. Somewhere in the early stages of syncing (Progress %3.68) i get an error called : System error while flushing: Fatal LevelDB error: Corruption: Block checksum mismatch: C:\users\amazi\appdata\local\bitcoin\chainstate\001325.ldb

Expected behaviour

I expected to be able to to sync the blockchain without any errors, especially early in. it doesn’t happen right away but it does happen.

Steps to reproduce

I just downloaded the Bitcoin Core 28.0 Version and verified Via Gpg keys for matching hash, then proceeded to sync with bitcoin-qt GUI on windows.

Relevant log output

i got another popup when i tried to exit QT.

Microsoft Visual C++ Runtime Library:

Assertion failed! Program c:\Program Files\Bitcoin\bitcoin-qt.exe file: txdb.cpp Line: 105

expression: old_heads[0] == hashBlock

for information on how your program can cause an assertion failure, see the visual c++ docs

not sure if this is relevant but thought i’d share it . it popped up after the original error pop-up.

Tried again, This time when i exited i didn’t get the Microsoft Visual C++ Error but it still gave me Fatal leveldb error, but this time instead of 001325, it was 001355, not the same block, why is this happening?

Bitcoin Core makes heavy use of CPU, RAM and disk IO. Hardware defects might only become visible when running Bitcoin Core. You might want to check your hardware for defects.

memtest86 to check your RAM
to check the CPU behaviour under load, use linpack or Prime95
to test your storage device use smartctl or CrystalDiskInfo
