The development of dynamic proof of work (dPoW) is still in its infancy. There aren’t many brand-new blockchain projects testing it.
It does, however, have some promise. In essence, dPoW prioritizes transactions according to how much labor the user has completed. So, you can offer more computational power rather than paying higher costs to complete your transaction more quickly. Your transaction will be prioritized higher by the network and processed more quickly the more processing power you dedicate.
The advantages are noticeable when the network is overloaded with low-value POW transactions, and you choose to allocate extra processing power to prioritize your transaction, pushing it ahead of the other transactions.
