Former Steem devs believe CPU mining is the key to a fair launch for their ‘blockchain 3.0'
But beyond that, Levine believes that the difficulty in deeply upgrading blockchains is what holds many protocols back:
While Koinos initially started as an alternative to Steem that would’ve drawn from existing codebases like EOS, the team realized over time that they had an opportunity to re-architect the "third generation of blockchain." This gives Koinos extreme flexibility in the design of its protocol, and notably, avoids the need to hard fork the entire blockchain for every change.
Such an idea is not entirely unique — the team was inspired by the concept of system smart contracts on EOS — but Koinos takes it to the extreme. The consensus algorithm often defines a blockchain, but Levine believes this should not be its unique selling point.
