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:

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.

Early in the age of disruption — whether of quantum technologies or widespread digital surveillance — even how we deal with time is being disrupted. DCalendar is a decentralized calendar that runs on NCOG blockchain — a quantum-resistant technology.

DCalendar brings us freedom, privacy, and efficiency to our most valuable resource — TIME. Welcome to a universe in which your time, your calendar, is not just arranged, but owned.

The Era of Quantum does Time Management

The “quantum age” is not something that’s just coming — it’s already here. It’s already remaking logistics, health care, cybersecurity and even some everyday routines. You probably won’t be using quantum devices to make phone calls any time soon. But, in the backend, quantum innovations are in the process of disrupting architectures of trust and security.

The incorporation of new quantum-safe encryption into scheduling systems, such as DCalendar, is a logical continuation of this trend. Not quantum computers in your pocket, mind you — rather, implementing quantum‑resistant technologies today to protect tomorrow’s digital infrastructure.

By using cryptographical primitives that are resistant to quantum attacks (commonly referred to as Post‑Quantum Security), DCalendar guarantees the privacy of notifications, event invitations, and of the scheduling metadata (i.e., the sharing of an agenda) even w.r.t. future quantum adversaries.

What Is DCalendar?

Key capabilities are:

Smart Booking & Shared Availability: Public booking links refresh automatically to show availability in real-time. Groups can share group slots, and have conflict detection and smart auto‑rescheduling across Synced Calendars.

Non-Reversible Event Logs: Once an event is stored, there is no way of reversing or deleting data from the blockchain — it’s written in stone and easily verifiable by all parties involved.

Quantum‑Secure Invites & Encryption: Safely swap invites and all necessary event details through post‑quantum encryption for guaranteed confidentiality.

Full Integration with D‑Suite: Integrates directly with decentralized email, contact, and identity — self‑sovereign in a single, unified environment.

These are all qualities that stand in stark contrast to a centralized calendar system, such as Google Calendar or Outlook, in which the hosting provider can modify, remove, or spy on the events within.

Why You Should Use DCalendar in the Time Economy of Today

Privacy & Ownership:

First, centralized calendars involve invasive tracking, profiling, and advertising dangers. They store vast reserves of personal information — where and when meetings will happen, what will be discussed, who will be attending — on corporate servers. These may be shared, leaked, or accessed without proper authorization.

By contrast, with DCalendar:

Users control their data entirely.

No one company can manipulate or sell your schedule.

They are explicitly given and can be revoked to your calendar.

You get to choose who sees your availability, and no third‑party operators get your email address.

Immutability & Trust

In the complex structures of universities, healthcare or government bodies, meeting overlaps, overwriting events, errors, and disputes are more likely to emerge. Dcalendar’s unchangeable record keeps all records unaltered so they can be seen and verified by all parties, eliminating disputes and boosting transparency.

Interoperability & Fluid Collaboration

DCalendar: Open Protocol, Peer‑to‑Peer DCalendar uses open protocols and peer‑to‑peer channels that enable it to work across devices, organisations, and apps — no lock‑in. All attendees on different networks can still see, facts‑check, and interact with the same schedule, live.

Scalability Challenges & Solutions

Blockchain calendars have a variety of problems to solve: how to propagate event updates to hundreds of nodes, low-latency issues, identity and authentication at scale, data storage efficiency, and scaling with a large number of concurrent users.

DCalendar Responders to this need include techniques such as sharding to distribute the load of the ledger, efficient peer‐to‐peer synchronization protocols and decentralized identity systems (DIDs) for authentication without any centralized servers.

These architectural features enable the DCalendar to scale with the organizations and the users, without sacrificing performance or security.

Manage Your Time: Productivity in the Quantum Age

Next-generation tools, from A.I. to quantum computing, could turbocharge productivity — yet untrammeled time (as in free, unrestricted by any prior commitments) continues to be the all-important bottleneck. Typical calendaring solutions can lead to back-to-back meetings, divided attention, and suboptimal focus time.

And DCalendar doesn’t just give users that control over their schedule, “it also provides the tools to keep and optimize your time:

Public booking links with live availability to remove friction on unnecessary negotiation and scheduling.

Automatic conflict detection and intelligent rescheduling, deepening the sense of the blocks being meaningful, intentional decisions.

Decentralized messaging and identity integration, allowing the user to schedule availability without leaking private metadata.

In a time when the demands on our attention and privacy are monumental, DCalendar lets users take control of their time — deciding when they are available, who can book them, and what interruptions are acceptable.

It’s in line with today’s productivity fads that advocate for time‑blocking, guarding deep work time, and being as thoughtful with your calendar as you are deliberate with your growth — only embedded in a secure, user‑centric platform.

Time, Sovereignty, and the Quantum Scale

A new era is dawning, one in which time is property — not in a philosophical sense, but where our time on our own schedules, digital histories and commitments is as securitized, controlled and owned as our value and our debt.

Quantum computing is, after all, both promise and peril. On the one hand, it brings advances in optimization, cryptography, drug design and AI. On the other hand, it poses a threat to traditional encryption mechanisms and to centralized systems that can be manipulated after the fact.

DCalendar anticipates this shift today. Its post‑quantum encrypted invites, decentralized identity, and immutable event logs are not just a gimmick — they’re protective infrastructure for the coming future. In a world where data longevity and durability are crucial, DCalendar ensures that your history and promises persist, even as networking architectures change.

Your calendar, in a way, is your quantum-resistant ledger of time — maintained, immutable, private.

Applications in Practice & Real-world Application

Freelancers and solopreneurs can send booking links connected to their real availability — and clients can book directly without middlemen or data leaks.

Synced calendar data enables conflict detection and auto-rescheduling for teams and working groups.

With blockchain, schools can tighten up class schedules, exams, and faculty assignments in a way that isn’t only transparent, but also auditable.

Appointments can be booked in a tamper‑proof log system for maintaining the integrity of data as well as preserving patient privacy.

In the corporate or regulatory sector, DCalendar provides both visibility and accountability with no central authority or risk of vendor.

Challenges & the Road Ahead

Decentralized calendar has problems. Despite the promise, decentralized calendars still hit roadblocks:

Adoption challenges: If you have users already invested in more mainstream tools, they may kick and scream against changing — especially if the interface or workflows are different.

Latency and synchronization delay: While architectural advances make a difference, distributed systems may be delayed relative to their centralized counterparts in some contexts.

Decentralized identity education: Few app users know what DIDs are, or how post‑quantum invites differ from the calendar invitations they use today.

However, NCOG and the D‑Suite architecture are still being further developed for usability, interoperability, and cross‑platform feasibility to overcome these early-stage issues.
