\section{Background}

\subsection{Decentralized Identity Systems}
|
|
|
|
Ethereum Name Service (ENS)~\cite{ens2017} pioneered blockchain-based naming using Dutch auctions for premium names and annual renewal fees. However, ENS faces namespace fragmentation across L2s and lacks cross-chain resolution.
|
|
|
|
Handshake~\cite{handshake2018} creates a decentralized root zone but requires running specialized resolvers. Unstoppable Domains~\cite{unstoppable2019} provides one-time purchase but lacks governance mechanisms.

\subsection{NFT-Bound Identity}
|
|
|
|
Soul-bound tokens (SBTs)~\cite{sbt2022} propose non-transferable tokens for identity. While SBTs prevent identity markets, they conflict with practical needs for key rotation and account recovery. Our approach uses transferable NFTs with staking requirements, creating economic friction without preventing legitimate transfers.
