Centralization of tokenized RWAs has a dark side: MEXC

According to Tracy Jin, chief operating officer of MEXC, the centralization of tokenized real-world assets has a dark side, especially if those RWAs are on permissioned or semi-centralized blockchains.

“Most tokenized assets will be issued on permissioned or semi-centralized blockchains,” Jin told Cointelegraph. “This gives authorities the power to issue restrictions or confiscate assets. The tokenization of assets such as real estate or bonds is still tied to the national legal system.”

The tokenized real-world asset market is expected to boom in 2025. The trend is driven by regulatory clarity, interoperability, solutions for liquidity, the evolution of identity from physical to digital, and even fractional ownership. According to RWA.xyz, the sector total market cap reached a high of $21.3 billion on April 21.
