Now the question is what is Hardfork?
The Hardfork provides the unit increase up to 8 MB.
Bitcoin Cash is probably the most famous and
successful Bitcoin network Hardfork.
While Hardfork does not support SegWit,
it provides protection from repeated transactions.
After Hardfork, Bitcoin holders had an equal amount
of Bitcoin Cash in their e-wallets.
Bitcoin XT is the first Bitcoin network Hardfork, which was held in August of 2015.
Bitcoin Diamond is the Hardfork, which happened at the end of November on the block 495,866.
Hardfork is a new network chain that is
formed when the new rules become incompatible with the old blockchain protocol.
In this case,
the nodes of the new and old networks would not be able to“communicate,” since Hardfork implies changing the consensus mechanism itself.
To implement Bitcoin XT it required 75% of all Bitcoin network miners to enter the new network,
but only 12% of them supported the Hardfork.
Developers believe that this Hardfork is intended to solve such problems as lack of privacy protection,
slow transaction confirmation, and high threshold for new participants to enter the network.
So In simple term, Hardfork is a process in which bitcoin's existing source
code modifies where some old protocols are replaced with new protocols and this process is known as bitcoin's Hardfork.
In this regard, a greater number of network users can mine Bitcoin Gold and the cryptocurrency motto is“make bitcoin decentralized again.”
Instead of the old Proof-of-Work protocol Hardfork initiators use the new one, Equihash.
The Hardfork, which is based on the source code of Bitcoin Core,
was supposed to increase the block size to 8 MB, thereby increasing the network bandwidth up to 24 transactions per second, but cryptocurrency did not gain the necessary support from the mining community.
