After further investigation into @MidnightNetwork , I realized that this project not only focuses on privacy but also addresses the cost-effectiveness of using blockchain. Instead of a 'pay-per-use' model, Midnight offers an approach based on owning $NIGHT to create DUST – a type of resource used to operate the network.
Notably, DUST is not permanently consumed but can be regenerated over time. This makes the experience of using blockchain feel like you have a stable 'source of energy', rather than being continuously affected by fluctuating transaction fees. For applications that need to operate frequently, this could be a significant advantage.
In addition, @MidnightNetwork uses zero-knowledge technology to ensure that data can be verified without being fully disclosed. The combination of privacy and a renewable resource model creates a fairly distinct approach compared to current blockchains.
In my opinion, if the ecosystem develops well, $NIGHT will not only be a token but also a "key" that helps users access blockchain services more effectively and sustainably.
