While bitcoin has been hitting new all-time highs on a regular basis this year, there are still issues that remain when it comes to how upgrades should be added to the network. For the past couple of years, the main area of focus on this perceived inability for bitcoin to upgrade has been the network’s block size limit.
As a quick refresher, the block size limit was the amount of data (transactions) that could be contained in a new block, which would then be added to the blockchain. The block size limit was 1 MB, but it has now been replaced by a 4 MB block weight limit.
