- PoW vs Security-Deposit-Based PoS:
- in PoW security, consensus should be more expensive for the network at all times than an attacker iswilling to spend at any time;
- In security-deposit-based PoS security, consensus should be cheap for everyone except for an attacker, during their attack. This is economically much more efficient.
- In PoS, consensus is ensured by depositing some value (money) that will be lost if the node behaves badly.
- My easier to maintain than PoW and much cheaper.
- Nodes must be online often enough to maintain the dynamic information (who is currently has active deposits) necessary for validating consensus
