Query: On Fairness in Committee-based Blockchains   Committee-based blockchains are among the most popular alternatives of
proof-of-work based blockchains, such as Bitcoin. They provide strong
consistency (no fork) under classical assumptions, and avoid using
energy-consuming mechanisms to add new blocks in the blockchain. For each
block, these blockchains use a committee that executes Byzantine-fault tolerant
distributed consensus to decide the next block they will add in the blockchain.
Unlike Bitcoin, where there is only one creator per block with high
probability, in committee-based blockchain any block is cooperatively created.
In order to incentivize committee members to participate to the creation of new
blocks rewarding schemes have to be designed. In this paper, we study the
fairness of rewarding in committee-based blockchains and we provide necessary
and sufficient conditions on the system communication under which it is
possible to have a fair reward mechanism.
