POW vs PoS: which is better?

POW is well tested and used in many cryptocurrency projects.

Blockchain DDoS attacks using this algorithm are not possible with today's computing technology. However, the high cost of energy, the negative environmental impact, the resulting unfavorable media coverage, the increasing centralization in mining, and the low transaction throughput will likely make it unviable in the long term.

Communities are increasingly concerned about the high electricity costs of bitcoin mining.

The PoS algorithm provides a more scalable blockchain with higher transaction throughput, and several projects have already adopted it, such as the DASH cryptocurrency.

However, POS is not perfect either. For example, during staking, an attacker can also commit fraud and confirm incorrect transactions.
