Mysten Labs, the developer of Sui, has presented a prototype of the Tessera network, designed for confidential calculations between companies. The solution is meant to hide transaction amounts from outside participants while preserving the ability for counterparties and regulators to obtain necessary information.
Mysten notes that the public visibility of amounts in most blockchain networks remains one of the main obstacles to their use in corporate settlements. Companies may be unwilling to conduct payments through networks where competitors can see their pricing and transaction volumes.
Tessera is built on Seal MPC multi-party computation technology and confidential transfers. In the prototype, a closed group of companies can conduct settlements for invoices using a confidential stablecoin. Access to the network is regulated by a Know Your Customer (KYC) procedure.
The blockchain records who made a payment to whom and when, but its amount is displayed in a hidden form to an outside observer. At the same time, the counterparty can see the full amount of their transaction, and a regulator can gain access to the necessary information.
Thus, a single transaction can have different levels of access depending on the participant's role.
Regulators Get Limited Access
Tessera provides differentiated access for supervisory bodies and other authorized parties. In particular:
- a prudential regulator can see all operations;
- a tax authority can see the operations of a specific participant;
- a dispute arbitrator can only see the transaction that is the subject of the dispute, and only during its consideration.
At the same time, none of these participants gains the ability to independently move funds.
The network operators retain consortium management functions. They can connect and fund participants, freeze individual users, or suspend network operations.
Tessera supports both one-time transfers and recurring payment channels. In case of a dispute, a transaction can be submitted to an arbitrator. The code for the Tessera prototype is open.
Recall that in May 2026, the Sui team removed fees for stablecoin transfers in the network.
