Sui, the layer-1 blockchain network, is adding confidential transfers that embed supply conservation directly into its protocol structure, co-founder and CPO Adeniyi Abiodun announced on X. The feature separates privacy and integrity enforcement: range proofs hide transaction amounts, while the network architecture itself makes unauthorized token minting structurally impossible. This design contrasts with systems like Zcash, where a single proof manages both functions, creating a larger attack surface. A past bug in Zcash's Orchard protocol allowed unchecked minting, highlighting the risks Sui aims to avoid.
According to Abiodun, the protocol does not rely on individual transaction proofs to confirm no new tokens were created; instead, the network enforces asset supply conservation at the foundational level. This reduces cryptographic overhead and strengthens security guarantees. The confidential transfers are part of a broader strategy that includes payment tools for AI agents and a decentralized storage layer called Walrus. The feature is still in advanced development with no specific launch date yet.
