  We propose a novel consensus protocol based on a hybrid approach, that
combines a directed acyclic graph (DAG) and a classical chain of blocks. This
architecture allows us to enforce collective block construction, minimising the
monopolistic power of the round-leader. In this way, we decrease the
possibility for collusion among senders and miners, as well as miners
themselves, allowing the use of more incentive compatible and fair pricing
strategies. We investigate these possibilities alongside the ability to use the
DAG structure to minimise the risk of transaction censoring. We conclude by
providing preliminary benchmarks of our protocol and by exploring further
research directions.
