Although the Bitcoin community has focused on an
increase in the
block size limit to
increase transactional capacity,
SegWit is able to achieve the same goal through alternative means.

SegWit and instead supports removing the Bitcoin blockchain's artificial

SegWit -
SegWit is a soft fork that changed the rules of the transaction format used in the Bitcoin blockchain and
increased the
block size limit.
Meanwhile, while these proposals were being put forward and tested, a group of major Bitcoin miners who previously supported the
SegWit2x proposal decided that deploying
SegWit without
increasing the
block size would not be sustainable, as it would simply delay the scaling issue due to the
size limit.

This effort was, to a large extent, spearheaded by proponents of a
block size limit
increase and opponents of the Segregated Witness (
SegWit) protocol upgrade, like Bitmain and Bitcoin.com.
However, some proponents of a
block size limit
increase hard fork (and opponents of

However, both coins followed different paths,
Segwit, on the one hand, was seeking to reduce transaction

While
Segwit aimed at compressing the amount of data in every transaction, hence freeing

block to a maximum of 8 megabytes.
Luckily there are two main proposed solutions: Bitcoin Unlimited, which aims to get rid of the
