Proof of Work algorithm in the public chain.
This is a hybrid algorithm. The algorithm is not typical. The algorithm is more secure than standard POW. There are no analogues at the moment. It is like a bipartisan political system. On the one hand, miners, on the other hand, coin holders. Each of the parties individually cannot influence the system as a whole.

Additional protection against attacks 51%.
Mining pools together will not be able to attack blockchain.
This algorithm is more environmentally friendly. You can save a lot of energy while maintaining the current security level of the blockchain compared to the standard POW.
