NIT: no need for an else statement here

Actually I do need the else here, because I am referencingn which only exists in the scope of the if statement.

Same reason the else exists.

Blake3 hashes are significantly faster than blake2 hashes used previously. Also added faster empty block detection so those don't need to get hashed at all. Signed-off-by: Alexander Wels <[email protected]>

Fixed the comment, the elses are still needed because of a variable only visible in the scope of the if statement. |
