How Do Hybrid Models like PoA Differ from Pure PoS in Terms of Network Security?
Hybrid models like PoA leverage the strengths of both PoW and PoS to enhance security. PoA uses PoW's resource expenditure for initial block creation, making 51% attacks more expensive than in pure PoS where an attacker only needs 51% of the staked coins.
The PoS part provides fast finality and lower energy consumption for validation. Pure PoS relies solely on the economic security of staked assets and 'slashing' penalties.
