ASBK (named after the authors' initials) is a recent blockchain protocol
tackling data availability attacks against light nodes, employing
two-dimensional Reed-Solomon codes to encode the list of transactions and a
random sampling phase where adversaries are forced to reveal information. In
its original formulation, only codes with rate $1/4$ are considered, and a
theoretical analysis requiring computationally demanding formulas is provided.
This makes ASBK difficult to optimize in situations of practical interest. In
this paper, we introduce a much simpler …
