Sui has introduced Tessera, a business-to-business payments and settlement network built to solve one of the key barriers to institutional blockchain adoption: the public visibility of transaction amounts.

Currently in prototype on the Sui blockchain, Tessera combines confidential transfers with Seal multi-party computation (MPC) technology to keep payment values hidden from the public. The design allows enterprises to leverage blockchain-based settlement without exposing commercially sensitive pricing, transaction sizes, or volume data to competitors, while still permitting authorized parties—including regulators and compliance officers—to access transaction details when necessary. The approach positions Sui alongside a growing segment of the blockchain industry attempting to make public networks viable for enterprise finance, where permissioned chains such as Hyperledger Fabric, R3's Corda, and JPMorgan's Onyx have traditionally dominated because they offer built-in privacy controls.

The Transparency Dilemma

Public blockchains make transaction details visible by default, offering transparency that supports verification and auditing. For financial institutions and businesses, however, that same transparency raises operational concerns. Prices, payment sizes, and transaction volumes can reveal commercially sensitive information, potentially undermining a company's competitive position.

Sui has noted that this issue has contributed to institutional hesitation around conducting real-world business transactions on public blockchain infrastructure. Companies may be reluctant to settle trades on networks where competitors can observe transaction values and draw inferences about commercial activity.

Tessera aims to overcome this limitation by introducing privacy controls while preserving the core benefits of distributed ledger technology. Counterparties can transact privately, with authorized entities retaining the ability to inspect relevant data when required.

Seal MPC Enables Confidential Transfers

A central component of Tessera is Seal MPC, which employs multi-party computation—a cryptographic method allowing multiple parties to jointly perform computations without revealing their individual inputs. MPC has been used in cryptographic research for decades and has increasingly been applied to digital asset custody, threshold signing, and privacy-preserving analytics. Applied to financial settlement, this technology enables transaction amounts to be validated and recorded without those values becoming publicly visible.

The selective disclosure model also addresses regulatory and compliance needs. Regulators, auditors, and designated compliance personnel could gain access to transaction information when appropriate, while competitors and the broader public would not. This mirrors a design philosophy seen in institutional blockchain projects that maintain "view" permissions for oversight—though Tessera's implementation on a public Layer 1 chain would be a distinguishing factor if successfully deployed.

Sui described Tessera in a post on X:

Tessera's selective-disclosure architecture seeks to merge commercial confidentiality with the oversight capabilities that regulated financial institutions require. The model represents a departure from the assumption that blockchain transparency must entail unrestricted visibility of every transaction detail.

Institutional Blockchain Adoption Moves Toward Privacy

The launch of Tessera reflects a broader trend toward blockchain infrastructure tailored to institutional requirements. Traditional financial institutions exploring digital assets increasingly demand systems that address operational, regulatory, and confidentiality concerns alongside transaction efficiency. The stablecoin-based settlement model referenced in Tessera's prototype aligns with a wider shift in B2B payments, where stablecoins have gained traction for cross-border settlement and treasury operations among financial institutions and fintech firms.

Privacy has become a critical requirement, as institutions may be unwilling to migrate existing financial activities to infrastructure that exposes sensitive commercial data. Tessera's design attempts to address this concern without eliminating the audit and oversight mechanisms expected by regulators.

If the prototype matures successfully, the network could support intercompany settlements, trade finance, and other B2B financial transactions where confidentiality is paramount. Such use cases could expand distributed ledger technology beyond publicly visible cryptocurrency transactions into more conventional business payments.

For Sui, Tessera offers an opportunity to demonstrate that its blockchain infrastructure can support enterprise-grade financial applications. Its success will hinge on whether institutions find the combination of confidential transactions, selective disclosure, and blockchain settlement practical enough for real-world deployment.

The prototype will serve as a key test of whether privacy-preserving blockchain infrastructure can achieve meaningful adoption among businesses and financial institutions while maintaining the regulatory visibility required for institutional operations.
