How does optical ASIC mining improve Kaspa's security efficiency?

Being friendly to optical ASICs means that more of the money spent securing the Kaspa network goes toward manufacturing hardware rather than paying electricity bills. In most proof-of-work networks, the ongoing cost of security is dominated by electricity — miners must keep paying for power every hour they run. ASICs, and optical ASICs in particular, shift that balance toward capital expenses: one-time hardware costs. The argument is that with the same total investment, you can achieve the same level of network security while burning less electricity — which matters for anyone concerned about the environmental footprint of cryptocurrency mining.
