Alternatively, you can fork an existing blockchain by taking the open - source code found
on Github —
Litecoin, for example —
making a few
changes, and launching a new blockchain with a new name (like Garlicoin).
It's interesting how much times have
changed by 2018; even @Excellion (Blockstream CSO)'s presentation explicitly
makes concessions to the non-maximalist multi-blockchain reality («lightning compatible with
Litecoin», «Simplicity will be usable
on Bitcoin + other blockchains»)
