Okay, ignore the blockchain part, what i meant is that the tool could have mechanisms to ensure trusted verification of task completions, decisions etc.

I share your experiences at large firm and startups . What I feel is that tech leads, Architects or Sr. Engineers have lot of stress to deal with when they have bad managers which is ultimately bad for the team , company and individual development.

I think my question should have been phrased a bit differently as some level of mgmt especially at Director or Sr. Manager level should be sufficient to take care of hiring/firing, budgeting etc. Also with better tooling , conflicts can also be minimized as they are caused by egoistic views which are not based on data (think pros/cons of a solution etc).

So in short first level managers and Project manager roles can be minimized and/or their roles adjusted as shared resources across teams, not as product owners and team managers which is a mostly redundant role.
