Proof of Work has been used in many fields for more than a decade. It's a consensus algorithm that is highly reliable and has been tested for years. Today, energy consumption has become a top priority, causing energy and environmental concerns. It is clear that Proof of Work needs to be improved.
Proof of Less Work was created to reduce the energy consumption of traditional Proof of Work without compromising decentralization. PoLW represents the first type of cost. This is the energy costs, which are external expenses that must be paid in real life and not on blockchain.
Second, coin burning is also known as internal burn since it occurs within the blockchain. If you add up both costs and compare them with PoW, the cost of an attack on PoLW is the same.
