06. CROCUS Private Protocol


CROCUS is our proprietary, private blockchain protocol. Is the foundation that smart contracts and crypto-assets can be built upon. Our protocol can easily support and integrate any kind of DApp, be it an enterprise-scale vertical solution or faster startups acceleration. A cross-platform protocol ready to be easily configured and deployed as the base layer of any solution, and effortlessly run using one-click installation. Implemented with highly scalable architectures and API integration native core modules, it can be adjusted for maximum capacity and velocity adoption.

Our ledger can run either as a private or a private/public (hybrid) blockchain platform. It can also be used as an immutable database framework providing complementary functionality to existing centralized software systems. Our fundamental element node in our ledger network of peers has been implemented in C++.

Our Smart contracts engine has been developed in Java SE and is running into a JVM, isolated for security reasons, inside each node.

Our application programming interface (API), is based on the powerful Apache.Thrift (RPC) architecture framework. For a really scalable, cross-language services development, it combines a software stack with a code generation engine to build services that can work efficiently and seamlessly among C++, Java, Python, PHP, Ruby, Erlang, Perl, Haskell, C#, Cocoa, JavaScript, Node.js or any other language.

Crocusledger architecture comes in private, hybrid or public flavors, with or without access permission ecosystem and is essentially a peer-to-peer, fully decentralized blockchain platform. It works via the Internet and uses the enhanced TCP/IP protocol to transfer data and commands between peers. The participants of the network interact with each other on the principle of peer-to-peer. All data transfer over the network of peers, uses the UDP transport protocol. The storage of blocks uses a high-performance Berkley DB, a NoSQL database for storing data in the key/value format with high compression algorithm, on transport and database layers. We are using strong cryptographic algorithms to ensure that our records are tamper proof.

A Crocusledger node consists of the following components, that comes in a signel executable file:

  1. The transport layer component
  2. The consensus component
  3. The Smart Contracts component
  4. The Database Framework component
  5. The API (RPC) component

Except the peers, we are also using a desktop wallet module, a web wallet module and the scanner of our ledger, in order to provide real-time monitoring of the ecosystem.

The code of Smart contracts is written in JAVA and runs in every single network node of Crocusledger. It implements a sequence of functions calls and program methods, inside or outside the network. They use oracles to read a data stream or fetch events outside the ledger, via the API. Smart contracts can run on multiple nodes simultaneously, may trigger any other contract, and they can be self-executable, based on scheduler or internal blockchain events. Our smart contracts can support any complex business logic and convert it to a Complete Turing Machine. Additionally, our smart contract executor works much like an IDE, which can be used for writing, compiling and deploying any kind of smart contract.

Crocusledger’s node and other modules are cross-platform software products. We have used C++, C# , Java SE , Javascript Frameworks, Apache.Thrift RPC API, NoSQL BerkelyDB technology stack and many efficient libraries and algorithms during development.

The system requirements required to run our ledger, are:

Hardware requirements : Minimum system requirements:

CPU: 1 GHz or better supporting  PAE, NX and SSE2; RAM: 2-4 Gb; HDD: 1 Gb; Internet connection speed: 3 Mbit/s;

Recommended System requirements:

CPU: Intel® Core ™ i3 or AMD Phenom ™ X3 8650; RAM: 4-8 Gb; HDD: SSD 1 Gb; Internet connection speed: 5 Mbit/s.

Operating system requirements : Operating system: Linux 64-bits / Windows® 7 / Windows® 8 / Windows® 10 64-bits (with latest updates).

Software requirements: Due to the active use of the Java language, an installation of JVM (JRE/JDK) on user’s computer is required.
