Do not get your "Blockchain" based technology mixed up with "Bitcoin" .... Some companies are using the "Blockchain" technology behind
Bitcoin for their projects. They do not want to use the "Bitcoin" token, so they develop something similar, but they use it on their legacy
ledger systems... These technologies are not permission-less and they are mostly private.
