Com base na análise recente de início de 2026, a Dusk Network é frequentemente descrita como operando com uma abordagem tranquila e de baixo alarde, que contrasta com o marketing barulhento de muitos projetos de blockchain. No entanto, sua arquitetura é construída para "falar alto" ao resolver requisitos complexos e de grau institucional que a maioria das cadeias evita.
A força arquitetônica da Dusk reside em seu foco especializado em RegDeFi (Finanças Descentralizadas Reguladas), combinando privacidade com conformidade legal, em vez de visar negociações especulativas, de alto volume e públicas.

O lançamento da Mainnet da Dusk Network no início de janeiro de 2025 (especificamente ativando no início de janeiro de 2026, de acordo com atualizações recentes) preparou o terreno para um progresso constante, transitando o projeto de uma fase teórica e experimental para uma blockchain funcional Layer-1 (L1) voltada para finanças compatíveis e de nível institucional. Ao focar em "privacidade auditável"—reconciliando requisitos regulatórios (KYC/AML/MiCA) com a confidencialidade dos dados—Dusk estabeleceu uma fundação projetada para crescimento sustentável a longo prazo, em vez de uma empolgação de curto prazo.

Plasma’s (XPL) focus on security and speed matters because it addresses the specific, high-stakes requirements of stablecoin payments, aiming to function as a, efficient, real-world financial rail rather than just another speculative crypto token. By optimizing for high-volume, low-cost, and secure transactions, Plasma bridges the gap between traditional finance and blockchain, particularly for remittances, merchant payments, and cross-border transactions.
Here is why Plasma's focus on these two pillars matters:
1. Why High-Speed Matters
In payments, user experience and finality are critical. Plasma is built to make stablecoin transactions feel instant.
Sub-Second Finality: Using a high-performance consensus called PlasmaBFT (based on Fast HotStuff), transactions settle in seconds. This provides "card network-like confidence" that payments won't be reversed, which is crucial for commerce.
Zero-Fee & Low-Cost Transactions: Plasma offers zero-fee USDT transfers, sponsored by a "paymaster" system that removes the need for users to hold special gas tokens. This makes micro-payments and day-to-day transactions economically viable.
High Throughput: Designed for high-volume, the network can process thousands of transactions per second, preventing the congestion and high fees typical of other networks during peak times.
2. Why Security Matters
Because Plasma handles real-world value (stablecoins), its security model is designed to be robust and trustworthy.
Bitcoin-Anchored Security: Plasma acts as a sovereign Layer-1 with its own validator set, but enhances its security by anchoring state roots (checkpoints) to the Bitcoin network. This adds a layer of trust-minimized security inherited from the most secure, decentralized chain.
Decentralized Validators: The network uses a decentralized validator set where participants stake the native XPL token to secure the chain, removing central points of failure.
Safety Against Malicious Actors: The architecture includes fraud proofs and challenge periods, allowing users to withdraw assets to the main chain even if a validator becomes malicious.
3. The Impact of This Focus (Why It Matters)
The combination of these features allows Plasma to act as a "payment-first" blockchain.
Real-World Utility: It targets practical use cases like cross-border salaries, remittances, and merchant checkouts in emerging markets (e.g., Southeast Asia, Latin America) where transaction fees are a major pain point.
Institutional Adoption: The secure, compliant, and high-speed design makes it attractive for fintechs, banks, and businesses that need reliable financial infrastructure.
Better User Experience: By allowing gas fees to be paid in stablecoins or covered by the protocol, it removes the friction of managing native tokens for every transfer, making it more accessible to non-crypto natives.
In essence, Plasma's focus ensures that stablecoins, which are often used for trading, can finally be used as a efficient, everyday medium of exchange. #PLASMA $XPL @Plasma

Walrus: Rethinking Decentralized Storage
Resilient Blob Storage

In the ever-expanding universe of blockchain infrastructure, Mysten Labs—the team behind the high-performance Sui blockchain—has launched one of the most ambitious decentralized storage protocols yet: Walrus. It aims to redefine the way decentralized applications interact with data itself: how it’s stored, accessed, verified, and priced.

While most blockchains struggle to handle large volumes of unstructured data, Walrus is engineered from the ground up as a decentralized blob store—designed to be fast, cheap, verifiable, and resilient. It brings together advanced erasure coding, tight coordination with the Sui blockchain, and a clean separation of roles across users, storage nodes, aggregators, and publishers. Together, these components form a robust, permissionless protocol that supports everything from AI datasets and ZK-proofs to media-heavy dApps and blockchain history.

This article explores the architecture and features of Walrus in-depth, walking you through how it works, what makes it different, and why it’s a foundational primitive for Web3 builders.

The Problem Walrus Solves
Traditional decentralized storage networks enable you to store files off-chain. But they rarely guarantee that those files are available when you need them, or that someone else hasn’t tampered with the content. For mission-critical apps—think AI agents, rollups, decentralized frontends—this is unacceptable. These apps need to:

Store large binary data (blobs) like videos, models, snapshots

Access it reliably, even if part of the network fails

Verify availability without needing the whole file

Do all this cheaply and programmatically

Walrus addresses these needs by introducing a verifiable, resilient blob storage layer that runs independently but coordinates tightly with the Sui blockchain.

What is a Blob?
The term “blob” stands for Binary Large Object. It refers to data that can’t easily be structured into tables or simple key-value pairs: images, sound files, AI model weights, blockchain snapshots, or JavaScript files.

Walrus is purpose-built to store and retrieve these kinds of unstructured data in a decentralized way. Crucially, it also lets users and smart contracts verify whether a blob exists and is available for use—without needing to download it in full.

The User Journey: How a Blob is Stored and Verified
To understand Walrus, let’s walk through the steps that happen when a user wants to store a blob:

Upload: A user (or publisher) submits the blob to the Walrus network using a CLI, SDK, or Web2 interface.

Encoding: The blob is split into slivers using an erasure coding algorithm called Red Stuff, which encodes the file into smaller pieces spread across many storage nodes.

Distribution: Each sliver is assigned to a storage node within a given storage epoch. These nodes commit to storing and serving their assigned slivers.

Proof of Availability: Once the nodes acknowledge receipt, the user collects signed attestations and combines them into an availability certificate.

On-Chain Attestation: The user uploads the certificate to the Sui blockchain, where it becomes a permanent record of the blob’s availability.

Verification: Anyone (including smart contracts or light clients) can now verify the blob’s availability on-chain by referencing this certificate.

This mechanism allows Walrus to guarantee that blobs are retrievable—even if two-thirds of the storage network goes offline.

Under the Hood: Red Stuff, Slivers, and Shards
At the heart of Walrus’s efficiency is its erasure coding protocol, Red Stuff. It solves a fundamental tradeoff in decentralized storage between replication cost and data resilience.

Rather than duplicating entire blobs across nodes (which would be prohibitively expensive), Red Stuff breaks each blob into slivers. These slivers are then grouped into shards, which are stored across different storage nodes.

Red Stuff enables:

Self-healing recovery when nodes go down

Low bandwidth requirements for repair

Verifiability in asynchronous networks, which prevents malicious nodes from exploiting network delays#WALRUS $WAL @WalrusProtocol

Decoding Red Stuff: Walrus's Engine for Resilient and Efficient Storage
Understanding the 2D erasure coding protocol at the heart of Walrus, and how it solves the trade-offs faced by existing decentralized storage systems.

Get Started
Product

Walrus's Red Stuff, a two-dimensional (2D) erasure coding protocol that defines how data is converted for storage, is at the heart of Walrus, enabling efficient, secure, and highly available decentralized storage.
Red Stuff enables Walrus to solve for the traditional trade-offs of decentralized storage, providing security, replication efficiency, and fast data recovery.
By using a matrix-based encoding process to create primary and secondary slivers, Red Stuff enables lightweight "self-healing," which unlocks rapid data recovery using minimal network bandwidth.
For builders, Red Stuff’s innovation translates to a storage network that’s more cost-effective, performant, resilient, and scalable.
Walrus, a decentralized storage and data availability network, addresses the limitations of traditional decentralized storage methods through a number of technical innovations, which are tailored to support binary large object (blob) storage.

Walrus’s Red Stuff encoding protocol, which defines how data is converted for storage, is at the heart of how Walrus provides high availability and integrity for blobs at scale.

Centralized cloud storage, while performant, introduces single points of failure, censorship risks, and misaligned incentives. Decentralized storage networks aim to improve on this by providing a credibly-neutral system for persistent data, but they face a set of fundamental trade-offs in order to do so.

Red Stuff allows Walrus to directly address the traditional trade-offs of decentralized storage with high security and efficient, uninterrupted availability, even in the case of storage node churn and outages. Overcoming these tradeoffs allows Walrus to match the performance of centralized cloud storage solutions without sacrificing the benefits of decentralization.

‍

Understanding the trade-offs of decentralized storage
Unlike centralized cloud storage, where data is managed by a single provider’s infrastructure, decentralized storage systems distribute data across many independent nodes. This improves resilience and censorship-resistance.

But, because storage nodes can leave the network or fail without warning (creating a ‘high churn’ environment), decentralization introduces new challenges in ensuring data remains available and durable. Availability can be achieved by replicating data across the network’s nodes; when individual nodes fail or go offline, the data they store can be rebuilt from other nodes’ redundant copies.

The unique challenges of churn and replication mean that decentralized storage networks must weigh fundamental trade-offs between several priorities:

Cost efficiency, which can be improved by minimizing replication overhead
Data durability and availability, which requires efficient data recovery, and the ability to continue operating correctly even when some storage nodes fail (fault tolerance)
Performance, including data retrieval latency and recovery speed
Security and trust guarantees, which include maintaining a sufficiently distributed and verifiable set of storage nodes
The method that a decentralized storage network uses to achieve data persistence in a high-churn environment directly impacts the trade-off between these priorities. Two commonly-used methods include full replication and one-dimensional (1D) erasure coding.

Full replication involves storing multiple complete copies of the data across different storage nodes. While this approach simplifies data retrieval and recovery — a new node simply needs to download one full copy from a peer — it suffers from extremely high storage overhead. To achieve a high degree of security there must be many copies of the data stored across the network. This makes full replication prohibitively expensive for large-scale data storage.
1D erasure coding, like Reed-Solomon (RS) encoding, offers a more space-efficient alternative. A file is split into data fragments, then ‘parity fragments’, or redundant pieces of data, are created mathematically from the original data fragments. The data file can be reconstructed from a subset of the fragments, significantly reducing the number of copies that must be stored across the network to achieve the same level of security as in full replication. However, 1D erasure coding has a critical weakness: to repair a single lost or corrupted fragment, the number of fragments that the node must download from its peers requires a data transfer equivalent to the entire original file size. In a dynamic network with frequent node churn, this high-bandwidth repair process becomes a bottleneck, limiting scalability and increasing operational costs.
The trade-offs between these common methods means that most decentralized storage networks must choose between the high cost of full replication and the inefficient recovery of 1D erasure coding.

Blobs and decentralized storage
‍Walrus is tailored to support binary large object (blob) storage, allowing builders to store, read, manage, and program large data and media files. Blob storage is valued for its flexibility, scalability, and ability to store traditionally hard-to-accommodate unstructured data.

Blobs are particularly useful for handling large data files — “large object” is in their very name. When it comes to storing and retrieving blobs, the storage overhead required for full replication isn’t practical, and the inefficient recovery of traditional erasure coding can represent a significant recovery bottleneck. Neither of the most common decentralized storage replication methods sufficiently meets the needs of blob storage at scale.

‍

Red Stuff: efficiency, without sacrificing recovery
One of Walrus’ core technical innovations is Red Stuff, a two-dimensional (2D) erasure coding protocol. Red Stuff is key to how Walrus can provide decentralized blob storage that’s highly redundant and secure, without sacrificing data recovery — even in the case of storage node churn and outages.

Red Stuff provides the storage efficiency of erasure coding, offering the same durability as full replication with a fraction of the replication overhead. It also solves the high-bandwidth recovery problem of 1D erasure coding methods like RS encoding, offering an efficient self-healing method.

For a full technical overview of how Red Stuff’s novel 2D erasure coding method works, read the Walrus Whitepaper. At a high level, while 1D erasure encoding fragments the original data one way (one dimension), 2D erasure encoding fragments the original data in two ways (two dimensions), which allows for more granular and efficient data recovery. The steps Red Stuff follows to encode a data blob help illustrate that process:

Matrix formation: The original data blob is first organized into a matrix of rows and columns. This matrix forms the basis of the 2D structure.
Primary encoding: Each of the columns in the initial matrix is treated as an independent data block. These columns are individually erasure-coded, which extends them into a larger, intermediate matrix. The source symbols in each row of this final matrix constitute a primary sliver.
Secondary encoding: In parallel, the rows of the initial matrix are also treated as independent data blocks. Each of these rows is erasure-coded, which extends them into a larger, intermediate matrix. The source symbols in each column of this final matrix constitutes a secondary sliver.
Sliver pair distribution: Following the encoding, the protocol assigns a unique pair of slivers — one primary sliver and one secondary sliver — to each of the storage nodes in Walrus’ active committee.#WALRUS $WAL @WalrusProtocol
