What Is the Concept of ‘Economic Security’ in PoS?

Economic security in Proof-of-Stake (PoS) is the security derived from the financial commitment and cost associated with attacking the network. It relies on the principle that the cost of acquiring a majority stake and the risk of losing that stake through slashing outweigh the potential gains from a malicious act.

This economic deterrent, rather than energy expenditure, is the primary defense mechanism against attacks like double-spending.
