Selective disclosure in $DUSK and why it matters for RWAs
Selective disclosure is a core advantage of $DUSK Network for real-world asset (RWA) tokenization because it enables privacy-preserving compliance. Sensitive information—such as trade size, investor identity, or portfolio exposure—remains hidden, while regulatory requirements are still proven using zero-knowledge proofs.
This approach significantly reduces data-exposure risk. Instead of broadcasting sensitive financial details on a public ledger, only authorized parties can access specific information via viewing keys. That aligns naturally with GDPR and similar data-minimization laws, shrinking the attack surface compared to fully transparent blockchains.
For institutions, selective disclosure removes one of the biggest blockers to RWA adoption: information leakage. Banks, funds, and issuers can satisfy KYC/AML obligations without revealing trading behavior or competitive strategies in mempools. This builds trust, supports deeper liquidity, and makes large-scale tokenization of assets like bonds, funds, or real estate commercially viable.
Issuers benefit from programmable compliance through Confidential Security Contracts. Transfer restrictions, eligibility checks, and audit conditions are enforced directly on-chain, automating compliance workflows. This lowers operational overhead, accelerates settlement, and still provides regulators with cryptographically verifiable audit trails when needed.
For end users, selective disclosure enables self-sovereign ownership of tokenized RWAs. Investors can hold fractional positions with confidentiality intact, improving accessibility without compromising security or decentralization.
Overall, selective disclosure bridges TradFi’s regulatory demands with blockchain efficiency. By resolving the long-standing tension between privacy and compliance, Dusk removes a key reason RWA pilots stall on other chains—making scalable, regulated tokenization practical rather than theoretical.
How does Dusk Network's selective disclosure mechanism work for RWAs
?
Dusk Network implements selective disclosure for real-world assets by combining zero-knowledge proofs with asset-level compliance logic, so only the minimum necessary information is revealed and only to authorized parties. Here is how it works step by step. Dusk uses a privacy-by-default transaction model called Phoenix. RWA balances and transfers do not exist as public account balances. Instead, they are represented as encrypted notes that only the owner can read. The blockchain verifies correctness using zero-knowledge proofs rather than by inspecting raw data. When an RWA is issued, it is wrapped inside a Confidential Security Contract (XSC). An XSC embeds regulatory rules directly into the asset itself, such as who is allowed to hold it, which jurisdictions are permitted, whether KYC or accreditation is required, and what transfer conditions must be satisfied. These rules are enforced cryptographically, not socially or off-chain. During a transfer, the user generates a zero-knowledge proof that shows all rules were followed. For example, the proof can show that the sender owns the asset, the recipient is on the correct whitelist, the transfer respects jurisdictional limits, and AML conditions are met. Crucially, this proof does not reveal the transaction amount, wallet identities, the full ownership history, or unrelated user data. The network validates the proof and finalizes the transaction without ever seeing the sensitive details. Selective disclosure happens only when oversight is required. If an auditor, regulator, or issuer needs verification, the asset holder can provide either a viewing key, or a targeted zero-knowledge proof. This reveals only the specific fact being requested, such as this holder is EU-verified, this transfer complied with MiCA rules, this bond ownership exceeds a reporting threshold, or this transaction does not involve sanctioned entities. Nothing beyond that scope is exposed. The rest of the user’s activity remains encrypted. Importantly, disclosure is consent-based and scoped. The holder explicitly authorizes what is revealed and to whom. There is no global backdoor and no permanent public exposure. This aligns with data-minimization principles under GDPR and financial privacy laws. From an RWA lifecycle perspective, this allows private issuance, private transfers, private dividend distributions, and private redemptions, while still enabling audits, regulatory reporting, and legal enforcement when required. The result is a system where the public ledger only sees cryptographic commitments, authorized parties see verifiable facts on demand, and institutions can operate on-chain without leaking trade data or client information. In short, Dusk’s selective disclosure mechanism turns compliance from a visibility problem into a cryptographic proof problem, allowing RWAs to be private by default, auditable when necessary, and usable at institutional scale without compromising either side. $DUSK #Dusk @Dusk_Foundation
How does slashing mechanism work for $WAL staking in @Walrus 🦭/acc
Slashing in Walrus secures WAL staking by penalizing poor storage performance.
Nodes stake WAL to join the committee and handle data slivers, with delegators adding to that stake for rewards.
Proof failures trigger slashing.
During epochs, nodes face random Proof-of-Availability challenges to prove they hold assigned slivers via Merkle proofs. Failing too many—due to downtime, lost data, or cheating—flags the node for penalties on its bonded and delegated WAL.
Slashing remains phased.
As of early 2026, full slashing activation is pending, but the mechanism burns partial stake for low performers and short-term stake churn that forces costly data migrations. This pushes delegators toward reliable nodes and burns WAL to create deflationary pressure.
Onchain enforcement ties it together.
Sui smart contracts track proofs, stake amounts, and failures, automating reward cuts or stake burns without manual intervention. Tolerating up to one-third faulty nodes aligns with BFT norms, excluding slashed nodes from future assignments.
Economic alignment prevents gaming.
Slashing rates, challenge density, and burn splits are governance-adjustable by WAL holders, ensuring long-term stakers favor high-uptime operators over risky ones.
