Sui to add confidential transfers to prevent unauthorized minting

Sui is adding a confidential transfers feature, co-founder and Chief Product Officer Adeniyi Abiodun announced on X. He explained that the main challenge for privacy cryptocurrencies is not hiding transaction amounts but ensuring no one can mint new tokens without authorization while the supply remains protected. Abiodun stated that Sui addresses this by narrowing its cryptographic verification to a single element: "range proofs" for the transfer amount. He stressed that the principle of asset supply conservation is embedded within the protocol's structure itself, rather than relying on individual proofs, making unauthorized issuance structurally impossible. The announcement follows a past incident where a bug in Zcash's (ZEC) Orchard protocol allowed for unauthorized token issuance, drawing significant community attention.
