The Citadel Network

Building A Digital Fortress For All Of Your Finances.

The Citadel Network is a peer-to-peer, decentralized cryptographic network where users can transact by sending economic value to one another.

The Citadel project comprises two primary entities - the Citadel Network, being the underlying blockchain-based cryptographically-secure infrastructure for sending economic value in the form of CTL tokens between users, and the Citadel Platform, a diverse and flexible ecosystem of digital, identity and e-commerce services for consumers globally.

All transactions are stored on a secure, shared public ledger known as the Citadel Blockchain, while being completely anonymous and reveal no information about the sender and receiver. The Network's robust distributed infrastructure serves as the backbone for the multi-layered, decentralized digital services architecture known as Citadel Platform.

Citadel Network Is:

The Citadel Platform

Bridging the adoption gap between Decentralized Ledger Technology and the Consumer Services Economy

The Citadel Platform is a secure, cost-effective and multi-faceted architecture for delivering digital services to anywhere in the world. Its primary application ecosystem, known as the Sentinel Framework, will serve as an open, flexible and fully programmable network of distributed nodes where decentralized applications (Sentinel Apps) can be hosted and run.

Leveraging the power of Citadel Network's underlying decentralized infrastructure and expanding its scope with the infinite flexibility that is afforded by the Sentinel Framework, allows the platform to create a wealth of immutable digital services with a cost-friendly commercial profile ready for mass business and consumer adoption.

Some of the key service components of the Citadel Platform are:

BitKYC - One Key. All Global Services.


BitKYC Protocol is Citadel Platform's Smart Identity Management Service (SIMS), and is an on-chain identity registration, encryption and verification service. The purpose of BitKYC is to create a viable mechanism through which digital identities can be created, administered and recognized by any service provider worldwide.

Each user's identity, once verified, grants the registrant a unique cryptographic key (C-Key) with which all services can be accessed seamlessly and securely. Such identities will be persistent and reusable across all services provided by Citadel Platform at first, and later on integrated into large scale, traditional ID-based services such as the ones provided by world governments, law enforcement agencies, financial and commercial service providers, regional authorities and others, and in doing so, Citadel aims to disrupt the fractured global landscape and create a consistent and unified method of identity management with equal participation for every global citizen.

BitKYC ensures that each person's unique identity corresponds to a cryptographic key that cannot be altered, cannot be compromised and cannot be stolen. Furthermore, due to Citadel Network's unique privacy-by-default nature, any identity issued by Citadel cannot be detected or discovered even before, after and during verification using BitKYC.

Sentinel Network - Create And Run Thousands of Decentralized Private Applications


Sentinel Network is Citadel Platform's robust, open, digital services architecture where developers can author decentralized applications (Sentinel Apps) using a set of built-in development tools, publish them to thousands of active, high-redundancy Sentinel Nodes around the world and have millions of users engage and collaborate with complete privacy.

Sentinel Nodes are Citadel Platform's main driver of scalability. These nodes are run trustlessly by network participants who receive a fee for on-demand service delivery and operation by consumers directly. As there are no centralized intermediaries involved and services are only consumed on-demand, the ecosystem creates the economic conditions needed to keep both consumers and service providers equally motivated to participate.

Citadel's redundant network architecture allows Sentinel Apps to seamlessly switch between multiple Sentinel Nodes in the event of node failure, eliminating the risk of database corruption and reduced availability. This allows applications to have operational and security assurances that are essential to mission critical business functions. The unique benefit afforded by this architecture is having a rich digital library of smart applications, without the need for a trusted third party, without performance trade-offs and without having your data trail collected without your knowledge or consent.

For mission-critical enterprise applications, publishers and can opt for using Citadel's Private Sidechains (CPS), which creates a private corporate environment that is permissioned and cannot be accessed by unauthorized entities. Due to Citadel Network's innate privacy features, private sidechains are truly private and their existence cannot be determined or tracked by any outsiders. This invariably leads to an increase in operational efficiency and lowers costs, making CPS-hosted Sentinel Apps well suited for driving large scale business adoption.

Private Smart Contracts - Enforceable, Encrypted Smart Business Agreements


With the introduction of private smart contracts, Citadel aims to provide a framework for creating, executing and verifying cross-party agreements with special commercial terms.

Understanding that sensitive commercial and financial data must not be compromised, Citadel leverages its audit-resistant blockchain infrastructure to ensure that contractual content remains invisible to unauthorized parties or publicly at all times, while allowing authorized parties to verify that agreed-upon terms are satisfied.

The ability to store data privately and securely on the Citadel Platform coupled with the ability to perform advanced conditional computation results in a very wide range of cross-industry business applications, such as enforcing real-world contracts, ensuring delivery-on-payment and counterparty compliance.

Private Side Chains - Blockchain-As-A-Service, Tailored To Your Business Needs


Citadel empowers business and individuals to create their own uniquely-tailored private blockchains that suit their individual needs.

Every Citadel launched sidechain will be a derivative of the main Citadel Blockchain, and have a two-way peg back to it, allowing for seamless exchange of information on-demand. Private Sidechains will be a store of data and value and can be run on any number of nodes around the world, making them ideal for use by decentralized applications and consensus-backed issued assets.

The main benefit is that Citadel sidechains will be private and not publicly visible, as well as have a set of custom configurable governing parameters that dictate each chain's nature, behavior, requirements, structure and pre-defined assets. Conversely, having dedicated chains for specific applications will offload computation and storage requirements from the main chain, allowing the Citadel to assign resources to more general purpose operations and network-wide data validation.

Citadel Assets - Secure Your Property On The Blockchain, Forever


Citadel Assets provide individuals, businesses and organizations with a mechanism to solidify ownership over both digital and physical real-world assets using the power of Citadel Network's trustless consensus.

As assets are issued on the Citadel Blockchain, being a decentralized and trustless public ledger, any risk of database corruption for any centralized organizations, whether governments or otherwise, is therefore eliminated. This ensures that any asset retains a persistent representation on the Citadel Blockchain that can be transacted and transferred at any time. Transferring of asset ownership can be supervised using Citadel's private smart contracts mechanism to ensure that ownership is retained until all contractual terms are fully carried out, creating powerful safeguards that are incorruptible or subject to individual interpretation.

To further solidify individual ownership, assets can be coupled with identity-based C-Keys, to protect against re-issuance under a different identity (asset double spend), and require a C-Key signature for any pending transaction involving the assets in question, adding a much needed layer of security against digital property theft. As identity association is strictly optional, Citadel Assets will allow anyone to own any asset without having to disclose their identity publicly, and will open the door to billions of unbanked world citizens in need of such a platform.
