This thread deserves a bump. Have IOTA or Byteball made any recent improvements to address Shelby Moore's concerns?
Neither byteball or Iota can be truly trustless or decentralised; they are flawed.
Byteball requires witnesses which are trusted super users in order to form a consensus:
Looking for a reality test, observe that some of the participants of our network
are non-anonymous reputable people or companies who might have a long
established reputation, or they are businesses interested in keeping the network
healthy. Well call them witnesses
Iota requires what they used to refer to as checkpoints, now known as 'coordinators' in order to maintain consensus until the currency is 'bootstrapped', which is years to never.
You cannot have a trustless concensus like bitcoin's without a mining reward - that is what creates convergence.
