Do you happen to have a source showing that Proof-of-Work (PoW) is more secure than Proof-of-Stake (PoS)? Most comparisons I've come across seems to show that PoS is more secure, especially when it comes to cryptoeconomic defense.
For example, PoS has built-in economic deterrents:
- As an attacker accumulates, the price of the token tends to rise, making the attack increasingly costly.
- Existing holders benefit from this price increase and can sell to the attacker, effectively extracting value from an attacker during an attempted takeover.
This is unique to PoS and doesn't exist in PoW, where the cost of an attack is external and doesn't get progressively more difficult to attack.
