Businesses need to start using agile methods and decentralization to develop, stay competitive, and stay secure. This is because of fast changes, a growing need for digital services, and the rise of AI and quantum computing. This all starts with making internal tasks like communication, scheduling, and storing and sharing data less centralized.

This means that we need digital tools that are more secure and provide users more control over their data than typical cloud suites.

That’s when DSuite comes in!

What is DSuite, exactly?

DSuite is a revolutionary suite of blockchain-based communication and productivity tools that provide businesses with complete control, security, and openness over their data and communication. DSuite is based on the environmentally friendly and long-lasting NCOG blockchain. It provides privacy-first decentralized communication, scheduling, identification, and storage solutions that are safe from threats posed by both classical and quantum computing now and in the future.

DSuite is perfect for professionals who care about their data and the environment because it has NCOG’s quantum-resistant cryptography, ultra-secure design, and green initiatives.

When you use blockchain-based decentralization, your data isn’t stored and controlled by a single server. Instead, you keep control of your organization’s data, which is safe because it is encrypted and stored on a dispersed network.

Important features of DSuite

No need for passwords: You don’t have to make and remember complicated passwords. You can log into DSuite with your Web3 digital wallet. Without passwords, there is no possibility of hacking them.

End-to-end encryption: All of the data in DSuite is safe since it is safeguarded by tamper-proof post-quantum encryption. This means that only you and the person or people you sent the message or file to can read it.

No data tracking: DSuite never records your emails, files, or other data for ads or analytics, unlike many other free cloud services. This means that your privacy and anonymity are guaranteed.

You own your data: There are no central servers or middlemen, so you have full control over your data.

With very secure Web3 capabilities, such Web3ID for signing in and validating identification, there is no chance of disclosing confidential information. Smart contracts for things like verifying transactions and keeping event logs also increase trust and automation.

Strong performance: NCOG’s high-throughput blockchain makes DSuite quick and responsive, allowing many users and transactions to happen at the same time at cheap prices.

In general, DSuite adds the benefits of decentralization, like security, privacy, and transparency, to everyday office products.

Important Modules of DSuite

These are the most important parts of DSuite that you can get right now:

DMail is an email service that uses blockchain technology and works like traditional email on the front end. But on the back end, it makes sure that your messages can’t be changed and are stored on a decentralized network that is safe from quantum attacks. No one else can read, scan, filter, or change your emails except the sender and the recipient(s). Not even DSuite’s providers can do this. It also has features like read receipts, delivery confirmations, and tamper-proof logs, all of which are safely stored on NCOG.

DCalendar: DCalendar makes sure that no one can delete or change an event, task, or meeting after it has been organized because everything is saved permanently on the blockchain network. With the same post-quantum encryption, even details and invitations are exchanged, so only the people who need to know know the facts.

Smart booking links that update in real time make sure that everyone can view open slots and avoid double booking without needing to coordinate from one place. You can send invites through DMail or DContacts because DCalendar works well with other DSuite technologies.

DContacts: Make and keep your address book on decentralized storage. You may also import and export contacts without worrying about data leaks. The blockchain makes sure that any updates you make to your contacts are synchronized across all of your devices.

DChat: DChat is a real-time messaging app like Slack or WhatsApp that sends messages directly between users with encryption. Your chat records are not stored on cloud servers.

DForms: DForms is a tool for making forms that encrypts answers and saves them on NCOG. Every form submission is protected from tampering, which makes it great for situations where privacy and data integrity are particularly important. DForms also works with DContacts, which lets you connect form responses to your contact list.

NCOG Wallet: Every DSuite user has (or can make) an NCOG Wallet, which is a secure digital wallet for keeping track of your DSuite identity and any digital assets, including the NEC utility tokens that run the network. You can log in without a password by using your wallet, which also stores the private keys that let you read your DMail, DChat messages, and other things. It’s made to be easy for new users to use but safe enough for advanced users.

In addition to the above, DSuite’s roadmap includes tools like DocSign (a way to sign documents on the blockchain for agreements), DStorage (a way to store files on the blockchain that is similar to Google Drive or Dropbox), DContacts (which will add more features to DContacts), DForms (which are already included as DForms), and even custom blockchain domain names and email addresses. The goal is to create a whole ecosystem of Web3 productivity apps that meet almost all of the needs that standard SaaS (Software-as-a-Service) suites do, but in a decentralized way.

What DSuite Can Do for You: Benefits

These are some of the best things of DSuite that set it apart:

Uncompromising Safety and Privacy

The best thing about DSuite is how secure it is. All of the data in DSuite is encrypted from start to finish, including emails, calendar events, contacts, and chat messages. Only the people who are supposed to can read and decrypt the data. Hackers can’t read your data even if they get it because they don’t have your private keys. Also, DSuite’s post-quantum security means that it uses encryption techniques that can’t be broken by the kinds of attacks that a quantum computer could launch in the future. This is really important for keeping things private in the long term. Your private messages now will still be safe ten years from now.

DSuite does not look through your files or data mine them. By default, everything you write or submit is completely confidential. The platform doesn’t even have the technological ability to read your information, let alone make money from it.

Also, because DSuite uses blockchain, each action, like sending an email or setting up a meeting, can leave a record (a hash) on the blockchain that can be checked. This makes it almost impossible for anyone to change records.

Control and Ownership of User Data

NCOG is committed to making you quantum-safe across your entire digital footprint.

Built on next-gen cryptography (CRYSTALS-Dilithium and SHA-3), NCOG leads the post quantum blockchain with a dedicated focus on security, carbon neutrality, and sustainability. This technology is engineered to withstand advanced quantum attacks, protecting encrypted communications, transactions, signatures, smart contracts, and other sensitive data.

Quantum Computers: A Rising Threat to the World

It was early 1980s when the concept of quantum computers was introduced by scientists (Richard Feynman and David Deutsch). They believed that the application of quantum mechanics in computers could make them supercomputers capable of performing complex computations faster than classical, binary systems.

And, they were right! Shor’s and Grover’s quantum algorithms proved them right, as these algorithms took just hours for complex problem-solving that would take years with classical computers. But soon, the technology became alarming in the 1990s, when mathematician Peter Shor proved that quantum computers could easily break RSA encryption, the very first digital security.

Is quantum computing a threat to your digital ecosystem? Unfortunately, yes!

Quantum computers open the door for hackers to attack your digital ecosystem using Grover’s and Shor’s algorithms. Also, hackers use other algorithms such as RSA, ECC, and some forms of hashing that are nearly impossible for classical computers to solve. It means in the coming few years, when powerful quantum computers become available easily, they could decrypt any encrypted data, be it your bank details, passwords, personal emails, or any other form of personal data.

Moreover, quantum attackers could derive private keys from public ones, to forge transactions, access wallets, and rewrite blockchain histories. According to Deloitte, encrypted data stored today could be hacked or changed in the future with quantum computers.

So, what’s the solution to quantum computing hacking?

The answer is post-quantum blockchain. This is next-generation blockchain technology that integrates quantum-resistant cryptographic algorithms to protect you from future quantum computer threats.

Are You Ready for Post Quantum Blockchain?

NCOG makes you post quantum ready. Our sustainable and advanced blockchain technology has the power to secure you against the threat posed by future advancements in quantum computing. It makes you quantum-ready, as its CRYSTALS-Dilithium and SHA-3 algorithms can easily mitigate quantum attacks. Regular security audits, code optimization, and hardening practices are conducted to identify and mitigate vulnerabilities. Additionally, quantum-resistant oracles and upgrade mechanisms are integrated in NCOG Earth Chain to maintain the security and integrity of smart contracts, ensuring they remain robust against both classical and quantum attacks.

Moreover, NCOG aims to set new standards in the blockchain industry by incorporating renewable energy and fostering community engagement. Additionally, this technology employs a combination of Proof of Stake (PoS) systems, Directed Acyclic Graph (DAG) structures, and the Forest Protocol to establish a secure, low-energy, and highly scalable blockchain environment.

Characteristics of CRYSTALS-Dilithium and SHA-3 algorithms

CRYSTALS-Dilithium

It is a lattice-based signature scheme that is a component of the CRYSTALS. NIST selected it as a primary digital signature scheme to fight against quantum attacks. Here are its characteristics:

Quantum-proof security: CRYSTALS-Dilithium is built on advanced math problems that even quantum computers can’t easily solve. Moreover, this algorithm depends on the hardness of three computational issues: Module Learning with Errors (MLWE), Module Short Integer Solution (MSIS), and SelfTargetMSIS, which makes it quantum-proof. It can easily resist powerful attacks like those enabled by Shor’s algorithm.

Fast and efficient: While offering strong protection, Dilithium is also a lightweight and fast algorithm. With it, you can quickly generate and verify many digital signatures, which makes it best for everyday use in blockchain networks, mobile apps, government documents, and more. In a study, performance improvements of over 80% have been found with the Dilithium algorithm.

Easy to use: With relatively compact key and signature sizes, Dilithium is easy to implement across different devices, including smartphones and embedded systems. You don’t need a number of processors and processing power to use it.

SHA-3

SHA-3 is a hashing algorithm that is used in the cryptography of modern computers to protect sensitive data and to maintain system security. It consists of six hash functions with digests (hash values) that are 128, 224, 256, 384, or 512 bits. Here are some of its characteristics:

Reliable: SHA-3 is a hashing algorithm that keeps your data safe and quantum-proof. It’s designed to withstand heavy cyber attacks that could be accelerated by quantum algorithms such as Grover’s.

Versatile: Unlike older hash algorithms, SHA-3 is flexible and built to adapt. It is best to use for securing transactions, generating digital identities, and verifying smart contracts.

Dive Deeper Into NCOG’s D-Suite: Future-Proof Tools

NCOG is more than just a blockchain — it’s a complete ecosystem of decentralized tools, designed to help individuals, organizations, and developers operate securely in the digital age or quantum computing era. Here’s what makes each tool of NCOG D-Suite a game-changer:

Also, there is built-in sharing and access control, for which you don’t need any third-party platform. It is best for organizations, DAOs, and remote teams to protect privacy from quantum attacks.

Choose Climate-Friendly Quantum-Safe Blockchain

NCOG offers a blockchain that targets two major issues of the time — quantum computers and climate change. Unlike traditional blockchain, which depends upon energy consumption, NCOG integrates renewable energy (solar power and other green energy sources) to fuel its blockchain network and data centers. This helps reduce the carbon footprint of the platform while supporting a more sustainable quantum-safe blockchain.

There is the Forest Protocol on NCOG — a unique system that ensures every transaction on the network is linked to a carbon offset initiative, specifically planting trees. This process is automated through smart contracts and verified using on-chain data. By contributing to global reforestation efforts, NCOG becomes a leader in green blockchain technology.

Novel Study Defines Essential Post-Quantum Boundaries for Distributed Lovász Local Lemma

Lovasz Local Lemma

Because of its inherent difficulty, the distributed Lovász local lemma (LLL) has long been considered a fundamental topic in the field of distributed computing. Recent years have seen a rise in interest in these complexity issues, and significant progress has been made in determining their computational boundaries. Researchers Tim Göttlicher and Sebastian Brandt of Saarland University and the CISPA Helmholtz Centre for Information Security have made a major breakthrough by establishing a precise lower restriction for solving the distributed LLL.

This groundbreaking study provides the first superconstant lower limit for both the well-studied sinkless orientation example and the more general distributed LLL problem. This achievement represents a major advance in understanding the inherent computational difficulty of these problems. By coming to this result, the researchers have directly addressed significant open questions in the field of distributed algorithms.

The team's findings establish a fundamental limit on the difficulty of resolving the distributed computing LLL problem. This constraint illustrates a fundamental restriction on the speed at which certain problems can be fixed in a distributed setting.

Reaching the Boundaries: Complexity and Models

To arrive at this conclusion, the researchers focused on sinkless orientation, a specific instance of the Lovász Local Lemma(LLL). They demonstrated that the given lower bound holds true even in computing environments that are regarded as more resilient or constrictive than the traditional O(1)-LOCAL model.

Crucially, the report accurately defines and employs the rigorous randomized online-LOCAL strategy. Computational nodes, which represent vertices in a graph, exchange messages with their neighbors during synchronous rounds. Each node has the ability to send and receive messages of any size and perform an endless number of internal calculations with the information it has gathered.

Nodes have significant limitations: they initially don't know the graph's general structure and only know a few local details, such their degree, the number of nodes (n), and the port numbers allotted to incident edges. In the randomized variant of this paradigm, every node is furthermore equipped with an endlessly long, private random bit string that influences its calculations.

Here, algorithm complexity is defined as the worst-case number of rounds needed for all nodes to terminate correctly. In order for the algorithms to have a high probability of generating accurate results, the probability must be at least 1−1/n, where n is the number of nodes. This is essential.

Crucially, the researchers also considered the quantum-LOCAL idea. This model improves on the randomized LOCAL model by utilizing qubits for quantum computing and communication. The paper demonstrates that the lower bounds hold rigorously for both the randomized online-LOCAL and quantum-LOCAL versions of the model. The result's broad application supports its broad significance across multiple study populations.

The Superconstant Barrier's Establishment

The study's primary achievement is the first superconstant lower limit for sinkless orientation and the more general distributed LLL problem across various relevant computing architectures.

The team's assessment of complexity validates a crucial constraint. Their approach involved analyzing the communication requirements seen in algorithms designed to solve the LLL problem. The findings demonstrate that any algorithm must execute at least Ω(1) communication rounds in the worst case. This solution is applicable to many other related models and provides the first superconstant lower limit for sinkless orientation and the more general LLL problem.

A New Method for Establishing Boundaries

The researchers employed a novel lower limit technique to measure this complexity. This new approach could serve as a universal tool for calculating bounds for a wide range of important problems studied in the location context.

Brandt and Göttlicher devised a technique that involved constructing a "construction tree." This building tree effectively encodes a set of behaviors that lead to a specific computational output. The study team is optimistic that this approach offers a promising path to even more durable lower bounds in the future, despite the fact that the size of graphs that the current architecture can reliably manage is restricted. They believe that this novel approach could lead to a new, generic approach to prove computation bounds for problems studied in the locality context.
