[1] The alternate networks may not die off if the hard
fork change proposed is a change to the mining algorithm itself.

Our goal in this section will, however, be to give an overview of all contentious hard
forks that occurred, cover their
proposed changes, provide the logic behind said
changes, and explore their resulting impact, if any.
Andresen
proposed a
change to the Bitcoin protocol that would implement an upward - scaling block size limit, necessitating a hard -
fork of the blockchain.
In the
proposed upgrade of the protocol
forks will be implemented if 75 % of the miners support the
change.
That's when Segwit2x, a proposal to
change the blockchain
proposed by business and miners, will move forward with a hard
fork aimed to boost the capacity of the bitcoin blockchain.
The soft
fork protocol
change proposed by the Bitcoin Core development team requires 95 percent hash power support from miners to activate — but has so far remained stagnant around 25 or 30 percent.
Bhardwaj referred to Segregated Witness (SegWit), a
proposed soft -
forking (backward compatible)
change to Bitcoin that includes an increase in the effective block size limit to more than 2 MB (after users upgrade to SegWit - enabled wallets), as a «small to medium level increase in the network capacity.»
While Bhardwaj claims increasing the block size limit via a hard
fork is not a complex alteration in terms of code
changes, the controversial aspect of such a
change is that it requires a hard
fork (and thus all users moving over to a new network), which can be difficult to coordinate — unless the
proposed change is itself uncontroversial.
If triggered, code
change also paves the way for other updates, including the Lightning Network (another
proposed scaling solution), and easier future soft
forks.
And they only
propose soft
forks that clearly signal that the protocol will
change, so all users can upgrade their software or take alternative precautions, if that is what they want.
Some parties aren't satisfied with how limited the
proposed changes are, and they even made a «hard
fork» to Bitcoin Cash.
The «no wallet
changes» part sounds rather confusing, which made users wonder if the
proposed update is really a hard
fork and how it would fit previous soft
fork solutions such as SegWit.
The other major upgrade for the Ethereum network, the Metropolis hard
fork, has been supposedly in the works long enough with several
proposed changes aimed at more mainstream adoption for the Ethereum.
Coordination is therefore required among all of these stakeholders to debate the merits of
proposed hard
fork changes and make hard but necessary decisions to ensure that the Bitcoin network continues to grow to support widespread usage.
