Are There Hybrid Consensus Models That Combine PoW and PoS?

Yes, hybrid consensus models that combine Proof-of-Work (PoW) and Proof-of-Stake (PoS) do exist. These models aim to leverage the strengths of both systems.

For example, a blockchain might use PoW for mining new blocks and PoS for validating them, creating a dual-layered security approach. This can help to improve security against certain types of attacks and can also be used as a transitional phase when a blockchain is migrating from PoW to PoS, as was the case with Ethereum's transition.
