  bibo_abstract:
  - 'In today''s cryptocurrencies, Hashcash proof of work is the most commonly-adopted
    approach to mining. In Hashcash, when a miner decides to add a block to the chain,
    she has to solve the difficult computational puzzle of inverting a hash function.
    While Hashcash has been successfully adopted in both Bitcoin and Ethereum, it
    has attracted significant and harsh criticism due to its massive waste of electricity,
    its carbon footprint and environmental effects, and the inherent lack of usefulness
    in inverting a hash function. Various other mining protocols have been suggested,
    including proof of stake, in which a miner''s chance of adding the next block
    is proportional to her current balance. However, such protocols lead to a higher
    entry cost for new miners who might not still have any stake in the cryptocurrency,
    and can in the worst case lead to an oligopoly, where the rich have complete control
    over mining. In this paper, we propose Hybrid Mining: a new mining protocol that
    combines solving real-world useful problems with Hashcash. Our protocol allows
    new miners to join the network by taking part in Hashcash mining without having
    to own an initial stake. It also allows nodes of the network to submit hard computational
    problems whose solutions are of interest in the real world, e.g.~protein folding
    problems. Then, miners can choose to compete in solving these problems, in lieu
    of Hashcash, for adding a new block. Hence, Hybrid Mining incentivizes miners
    to solve useful problems, such as hard computational problems arising in biology,
    in a distributed manner. It also gives researchers in other areas an easy-to-use
    tool to outsource their hard computations to the blockchain network, which has
    enormous computational power, by paying a reward to the miner who solves the problem
    for them. Moreover, our protocol provides strong security guarantees and is at
    least as resilient to double spending as Bitcoin.@eng'
