Lack of privacy is a barrier to both everyday and institutional use of crypto and blockchain technology, CZ and institutions argue.

What to know:

  • Crypto leaders including Binance co-founder Changpeng Zhao warn that the radical transparency of public blockchains is deterring mass adoption of crypto.
  • Institutional executives at firms such as Abraxas Capital, JPMorgan and B2C2 say large transactions require privacy so that only authorized parties can see who is behind deals, even as activity remains auditable.
  • A recent $50 million commercial paper issuance on Solana by JPMorgan and Galaxy Digital showcased the promise of tokenized debt but also underscored that institutions will not move assets on-chain at scale until privacy and execution certainty improve.
