Dusk is the privacy blockchain for regulated finance.
It lets you launch and use markets where:
Institutions can meet real regulatory requirements on‑chain
Users get confidential balances and transfers instead of full public exposure
Developers build with familiar EVM tools plus native privacy and compliance primitives
Dusk combines:
Zero‑knowledge technology for confidentiality
On‑chain compliance for MiCA / MiFID II / DLT Pilot Regime / GDPR‑style regimes
Succinct Attestation, a PoS consensus protocol for fast, final settlement
A modular architecture with DuskDS (data & settlement) and DuskEVM (EVM execution)
What is Dusk?
Most financial markets still run on opaque, centralized systems.
Dusk is built to move those workflows on‑chain without sacrificing:
Regulatory compliance
Counterparty privacy
Execution speed and finality
On Dusk, institutions can issue and manage financial instruments while enforcing disclosure, KYC/AML, and reporting rules directly in the protocol.
In short: Dusk is a privacy-enabled, regulation-aware blockchain for institutional-grade finance.
Why Dusk?
Built for regulated markets
Dusk is designed around the needs of regulated financial institutions:
Native support for compliant issuance of securities and RWAs
Identity and permissioning primitives that let you differentiate between public and restricted flows
On‑chain logic that can reflect real‑world obligations (eligibility, limits, reporting, etc.)
See: Core Values and Tokenization & Native Issuance.
Privacy by design, transparent when needed
Dusk uses zero‑knowledge proofs and dual transaction models (Phoenix and Moonlight) to let users choose between:
Public transactions for transparent flows, and
Shielded transactions for confidential balances and transfers,
with the ability to reveal information to authorized parties when required.
See: Cryptography and Transaction Models on Dusk.
Fast, final settlement
The Succinct Attestation consensus protocol is a proof‑of‑stake, committee‑based design:
Deterministic finality once a block is ratified
No user‑facing reorgs in normal operation
Designed for high throughput and low‑latency settlement suitable for markets
For the full consensus specification, see Section 3 “Consensus mechanism” of the Dusk Whitepaper (2024).
Modular & EVM-friendly
Dusk separates settlement from execution, making it easier to match the right environment to each use case:
DuskDS – consensus, data availability, settlement, and the privacy‑enabled transaction model
DuskEVM – an Ethereum‑compatible execution layer where DUSK is the native gas token
Native bridging between layers so assets can move where they’re most useful
See: Core Components and DuskEVM Developer Docs.
What can you build on Dusk?
Some example use cases Dusk was designed for:
Regulated digital securities
Tokenized equity, debt, or funds with embedded compliance rules
On‑chain corporate actions and transparent yet privacy‑respecting cap tables
Institutional DeFi
Lending, AMMs, and structured products that must enforce KYC/AML
Separation of public market signals from private position details
Payment & settlement rails
Confidential payments between institutions
Delivery‑versus‑payment (DvP) settlement of tokenized assets
Self‑sovereign identity & access control
Permissioned venues where access is controlled via verifiable credentials
Compliance checks enforced in smart contracts instead of manual back‑office processes

Walrus is an innovative decentralized storage network for blockchain apps and autonomous agents. The Walrus storage system is being released today as a developer preview for Sui builders in order to gather feedback. We expect a broad rollout to other web3 communities very soon!
Leveraging innovations in erasure coding, Walrus enables fast and robust encoding of unstructured data blobs into smaller slivers distributed and stored over a network of storage nodes. A subset of slivers can be used to rapidly reconstruct the original blob, even when up to two-thirds of the slivers are missing. This is possible while keeping the replication factor down to a minimal 4x-5x, similar to existing cloud-based services, but with the additional benefits of decentralization and resilience to more widespread faults.
The Replication Challenge
Sui is the most advanced blockchain system in relation to storage on validators, with innovations such as a storage fund that future-proofs the cost of storing data on-chain. Nevertheless, Sui still requires complete data replication among all validators, resulting in a replication factor of 100x or more in today’s Sui Mainnet. While this is necessary for replicated computing and smart contracts acting on the state of the blockchain, it is inefficient for simply storing unstructured data blobs, such as music, video, blockchain history, etc.
Introducing Walrus: Efficient and Robust Decentralized Storage
To tackle the challenge of high replication costs, Mysten Labs has developed Walrus, a decentralized storage network offering exceptional data availability and robustness with a minimal replication factor of 4x-5x. Walrus provides two key benefits:
Cost-Effective Blob Storage: Walrus allows for the uploading of gigabytes of data at a time with minimal cost, making it an ideal solution for storing large volumes of data. Walrus can do this because the data blob is transmitted only once over the network, and storage nodes only spend a fraction of resources compared to the blob size. As a result, the more storage nodes the system has, the fewer resources each storage node uses per blob.
High Availability and Robustness: Data stored on Walrus enjoys enhanced reliability and availability under fault conditions. Data recovery is still possible even if two-thirds of the storage nodes crash or come under adversarial control. Further, availability may be certified efficiently without downloading the full blob.
Decentralized storage can take multiple forms in modern ecosystems. For instance, it offers better guarantees for digital assets traded as NFTs. Unlike current designs that store data off-chain, decentralized storage ensures users own the actual resource, not just metadata, mitigating risks of data being taken down or misrepresented.
Additionally, decentralized storage is not only useful for storing data such as pictures or files with high availability; it can also double as a low-cost data availability layer for rollups. Here, sequencers can upload transactions on Walrus, and the rollup executor only needs to temporarily reconstruct them for execution.
We also believe Walrus will accompany existing disaster recovery strategies for millions of enterprise companies. Not only is Walrus low-cost, it also provides unmatched layers of data availability, integrity, transparency, and resilience that centralized solutions by design cannot offer.
Walrus is powered by the Sui Network and scales horizontally to hundreds or thousands of networked decentralized storage nodes. This should enable Walrus to offer Exabytes of storage at costs competitive with current centralized offerings, given the higher assurance and decentralization.
The Future of Walrus
By releasing this developer preview we hope to share some of the design decisions with the decentralized app developer community and gather feedback on the approach and the APIs for storing, retrieving, and certifying blobs. In this developer preview, all storage nodes are operated by Mysten Labs to help us understand use cases, fix bugs, and improve the performance of the software.
Future updates to Walrus will allow for dynamically changing the set of decentralized storage nodes, as well as changing the mapping of what slivers are managed by each storage node. The available operations and tools will also be expanded to cover more storage-related use cases. Many of these functions will be designed with the feedback we gather in mind.
Stay tuned for more updates on how Walrus will revolutionize data storage in the web3 ecosystem.
What can developers build?
As part of this developer preview, we provide a binary client (currently macOS, ubuntu) that can be operated from the command line interface, a JSON API, and an HTTP API. We also offer the community an aggregator and publisher service and a Devnet deployment of 10 storage nodes operated by Mysten Labs.
We hope developers will experiment with building applications that leverage the Walrus Decentralized Store in a variety of ways. As examples, we hope to see the community build:
Storage of media for NFT or dapps: Walrus can directly store and serve media such as images, sounds, sprites, videos, other game assets, etc. This is publicly available media that can be accessed using HTTP requests at caches to create multimedia dapps.
AI-related use cases: Walrus can store clean data sets of training data, datasets with a known and verified provenance, model weights, and proofs of correct training for AI models. Or it may be used to store and ensure the availability and authenticity of an AI model output.
Storage of long term archival of blockchain history: Walrus can be used as a lower-cost decentralized store to store blockchain history. For Sui, this can include sequences of checkpoints with all associated transaction and effects content, as well as historic snapshots of the blockchain state, code, or binaries.
Support availability for L2s: Walrus enables parties to certify the availability of blobs, as required by L2s that need data to be stored and attested as available to all. This may also include the availability of extra audit data such as validity proofs, zero-knowledge proofs of correct execution, or large fraud proofs.
Support a full decentralized web experience: Walrus can host full decentralized web experiences including all resources (such as js, css, html, and media). These can provide content but also host the UX of dapps, enabling fully decentralized front- and back-ends on chain. It brings the full "web" back into "web3".
