What Is the Practical Block Size Limit in Bitcoin?
The practical block size limit in Bitcoin is approximately 4 MB, introduced with the SegWit upgrade. This is not a strict size limit but a ‘block weight’ limit of 4 million weight units.
This allows for a greater number of transactions, especially SegWit transactions, than the original 1 MB size limit.
