Babylon: Reusing Bitcoin Mining to Enhance Proof-of-Stake Security. (arXiv:2201.07946v1 [cs.CR])

Bitcoin is the most secure blockchain in the world, supported by the immense
hash power of its Proof-of-Work miners, but consumes huge amount of energy.
Proof-of-Stake chains are energy-efficient, have fast finality and
accountability, but face several fundamental security issues: susceptibility to
non-slashable long-range safety attacks, non-slashable transaction censorship
and stalling attacks and difficulty to bootstrap new PoS chains from low token
valuation. We propose Babylon, a blockchain platform which combines the best of
both worlds by reusing the immense …
