Blockchain is enabling the development of applications which do not rely on a centralized party for operation, meaning they can be more resilient, autonomous, and secure than their traditional counterparts. Immune to single points of failure and censorship resistant, users of decentralized applications themselves benefit from increased control and autonomy. The use of blockchain-based architecture means DApp users can be verifiably sure of the control of their own data and digital presence. Decentralized applications undoubtedly harness the potential to revolutionize much of our digital experience, firmly placing the power into the hands of the users… but not as they stand today. Despite the existence of upwards of 10 blockchain platforms in the top 50 projects by market cap alone, DApps remain a niche subsection of overall application development and usage. According to DApp Radar almost half of the most popular decentralized apps are gambling-related, with the top 5 DApps reportedly garnering just over 30K users in a 24h period; for context, Facebook claims over 1.5 billion daily active users, and MySpace (the social network everybody forgot about 8 years ago) still receives over 200K visits per day alone. We still have a very long way to go to mainstream adoption. Why so little interest in DApps at a practical level? Because DApps in their current form are unintuitive and uninteresting , severely limited by the constraints of their chosen blockchain’s architecture and the barrier to entry of a complex programming language. Although the blockchain space is still in its fledgling phase, it’s important to note that we are already encountering hurdles on the DApp development front which present huge fundamental problems if we are to ever take DApps mainstream. Chromia looks to overcome these hurdles through combining relational databases with blockchain, providing several notable advantages to current platforms and opening the door to new possibilities in the field of DApp development. In order to achieve mainstream adoption of DApps, Chromia believe current blockchain architecture and programming models need to be seriously reimagined. Inspired by the shortcomings of existing platforms, Chromia is a designed with the requirements of developers and users explicitly in mind, built to facilitate the creation of genuinely scalable, secure and feature-rich decentralized applications. What if DApps could be written in a language and with a programming model already familiar to developers? What if a single DApp could scale to millions of users by utilising its own blockchain? What if DApps could be empowered with the autonomy to decide their own resource allocation, governance rules and economic model? Chromia is looking to provide the answers. # Current Industry Situation: In Need of Innovation There are two key aspects which severely limit DApp development and usage in the current blockchain environment: poor developer experience and limited performance capacity. From a developer’s perspective, the current complex blockchain programming languages are unfamiliar and difficult to learn. Ethereum provides a much higher level programming language than that of Bitcoin, but their programming model is inherently riddled with security risks (leading to instances such as the infamous DAO hack). This presents a huge barrier to entry on the developer level. Established networks are consistently congested and the transaction processes are too lengthy to be realistically usable for high-user-volume DApps. When CryptoKitties overloaded the Ethereum blockchain in December of 2017, the problem was caused primarily by the activity of the 14,000 daily users of the cat-based DApp which it had at its peak… just 14,000! The congestion didn’t just affect users of the DApp; the event impacted the whole Ethereum ecosystem. Even as of now, there is no solution which enables Ethereum to act as a reliably fast and scalable smart contract system. ![1 n153XSECk8m-GmDfZaZDug.jpeg](https://cdn.steemitimages.com/DQmRL3WHjBXHqcgog7JwpbdYAx2bqqdYqi7oXK1RUvbsYBE/1%20n153XSECk8m-GmDfZaZDug.jpeg) > The cute blockchain-hosted cats caused huge problems for the Ethereum network and exposed the scalability limitations of conventional blockchian platforms Existing blockchain protocols are simply not up to the task of facilitating the creation or maintenance of large-scale dapps designed for mainstream use; the required infrastructure and tools are not present. What’s required is clearly nothing less than a total reimagining of current blockchain architecture and programming models. # Chromia’s Solution: An Evolution in DApp Development Essentially, Chromia’s goal is to build a platform which offers superior performance for decentralized applications, whilst providing the tools to make development as easy as possible for developers of all backgrounds. This is not an easy task; to effectively tackle some of the industry’s toughest problems, a systematic multi-pronged approach is required. ## Familiar Programming Model Chromia aims to empower developers by enabling them to build decentralised applications without prior blockchain experience, which is reflected in the platform’s programming model. Below the surface, Chromia acts in the same way as a relational database- the same model as with traditional enterprise applications. This makes for simple and efficient data store and query capabilities. Rell, Chromia’s native programming language, is explicitly designed to be easy to learn for programmers whilst being type-safe, safety-optimised, concise, expressive and convenient; no other existing language has this feature set. Employing a relational model and programming language removes the unnecessary complexity of blockchain and transforms the process of development into something much more familiar for general programmers. This means easy onboarding of developers and huge incentives over existing blockchain platforms for them to do so- programming on Chromia is designed to be a familiar experience for the wider developer community, inherently breaking down multiple barriers to entry. ## Performance & Scalability Chromia is designed to be highly scalable from its very inception. At the core, the platform utilizes Practical Byzantine Fault Tolerance (PBFT), which means it can handle a large number of transactions- up to 1000 transactions per second per blockchain. Yes, I said per blockchain. That’s because each application in the Chromia ecosystem will run on its own independent blockchain (or multiple blockchains acting as sidechains if greater performance is required), enabling a high I/O rate and easy horizontal DApp scalability. Through Chromia’s approach, individual DApps will be able to easily scale to millions of users. ![Chromia Diagram.jpg](https://cdn.steemitimages.com/DQmdsFXBNCBQ8pFBGt2kVzqzTuinc75dfgR63NTNP4D9CVR/Chromia%20Diagram.jpg) > Outline of Chromia's network architecture Individual applications will bear their own costs and will be responsible for the implementation of their own resource management. This allows for a new level of DApp-level flexibility and autonomy. Because each is running on its own blockchain, any mismanagement or overloading of the network of one DApp will remain problematic for that specific chain only, and will not interfere with the wider Chromia ecosystem. ## Secure Consensus Mechanism There is much argument in the blockchain space as to the most effective consensus mechanism- is it Proof of Work (PoW), Proof of Stake (PoS), or something else entirely? Each has its strengths and drawbacks, igniting heated debate regarding the trade-off between security and decentralization. Chromia believe the answer lies in a mixture of existing approaches, and are therefore adopting a hybrid consensus mechanism primarily based on the PBFT model. As a Byzantine fault tolerant network, Chromia will be resistant to arbitrary and potentially malicious behaviour, enabled to correctly reach a sufficient consensus despite malicious actors (nodes) in the system failing or propagating incorrect information to other peers. Chromia’s PBFT mechanism is further secured by anchoring Chromia chains to a PoW blockchain, such as Bitcoin. In this way, the finality of confirmed transactions can be as much guaranteed as that of the anchoring blockchain (i.e. transaction integrity will be as secure as that of Bitcoin transactions, if anchored to the Bitcoin blockchain). ## Gaming Use Case: Power to the Players As a general-purpose platform, Chromia is suitable for almost all types of dapps, but is particularly well suited to use cases requiring high I/O capacity or involving management of complex data sets. Massively multiplayer online games (MMOGs) are such an example, which also present an excellent way to demonstrate the performance capabilities of the platform; entire worlds can be built on top of Chromia’s decentralized infrastructure. It’s for this reason that gaming is one of the primary initial focus points for the team. Chromia want to prove the enormous scalability potential of their platform through practical demonstration- let the tech speak for itself. Each DApp in the Chromia ecosystem is entirely free to set its own governance rules and procedures, enabling unparalleled DApp-level autonomy and presenting a plethora of possibilities in the way of economic models and community governance structures. Taking gaming as an example, players could form a sort of ‘mini democracy’, whereby changes to game logic such as patches or updates can only be implemented if agreed upon by the majority. Further, because the system is hosted on Chromia’s decentralized infrastructure, in the event of a game company deciding to discontinue development of their Chromia dapp, for example, the community would be free to cover the upkeep costs of the network and take the reins; in this scenario, if the public demand is there, the community have the power to implement their own will. Essentially, Chromia is providing the infrastructure, mechanisms and tools to completely revolutionize the gaming experience– to mention just one of their limitless use cases. # Team Overview: The Innovators Behind Chromia As I always say, anybody can write an impressive whitepaper and create a persuasive website; the idea is the easy part, it’s the implementation of the idea which is difficult.
