NFTs introduced a new way for digital creators to sell their work directly to collectors. But one of their most talked-about features goes beyond the initial sale: NFT royalties.

Cryptocurrency was built on the idea that people should not have to blindly trust a central authority. Instead, networks can use transparent rules, cryptography, and distributed consensus to let participants independently verify what is happening. Open-source software is a natural extension of that philosophy.
