  bibo_abstract:
  - 'This paper explores a modular design architecture aimed at helping blockchains
    (and other SMR implementation) to scale to a very large number of processes. This
    comes in contrast to existing monolithic architectures that interleave transaction
    dissemination, ordering, and execution in a single functionality. To achieve this
    we first split the monolith to multiple layers which can use existing distributed
    computing primitives. The exact specifications of the data dissemination part
    are formally defined by the Proof of Availability & Retrieval (PoA &R) abstraction.
    Solutions to the PoA &R problem contain two related sub-protocols: one that “pushes”
    information into the network and another that “pulls” this information. Regarding
    the latter, there is a dearth of research literature which is rectified in this
    paper. We present a family of pulling sub-protocols and rigorously analyze them.
    Extensive simulations support the theoretical claims of efficiency and robustness
    in case of a very large number of players. Finally, actual implementation and
    deployment on a small number of machines (roughly the size of several industrial
    systems) demonstrates the viability of the architecture’s paradigm.@eng'
