**6. Conclusion**

NFTs pose huge market and legal challenges, which should be guided by legislators with full respect to technological neutrality and entrepreneurial innovation initiative in PPDL emerging networks.

Fungibility is a legal-economic concept concerning tokens and their underlying assets. Forthcoming NFT regimes still dismiss this dichotomy and its relevance for the right insertion of tokens in legal taxonomies entailing the applicability of securitieslaw requirements (like EU MiFID2 primary-market rules) or crypto-asset specific laws (like MiCA Regulation), and their further developments concerning NFT ownership and transferability of rights tied to their exchange in DeFi platforms.

In the field of IP, effective protection of NFT purchasers demands additional efforts to balance the interests of DLT-platform managers and DApp industry with adequate protection of IP rights and authors of digital art. Such balance is necessary too for effective protection of investors and purchasers of rights linked to NFTs in the cases of gambling, money-laundering and macro-financial instability involving in DeFi NFT illicit trading. PPDL architecture surveillance is an excellent vehicle to this extent, requiring bespoke intervention in node governance, both on and off chain.
