OPEN Platform
Blockchain-based Platform for Smart Contracts
OPEN platform makes it easy for developers to connect their applications to multiple blockchain networks with little or no blockchain experience.
OPEN is a developer wallet that provides a simple way to allow existing (off-chain) applications to accept (on-chain) payments such as cryptocurrencies. This allows developers to expand their services and build robust applications with custom smart contracts written in popular languages like JavaScript, Python, Kotlin, Java, Scala (all the JVM family) without having to learn additional languages.
Technology Used
Kotlin
Javascript
Solidity
Biggest Challenge
Building a high throughput network while creating a platform that was easy for developers to interface with, without requiring them to learn new languages.
A Successful Innovation Enabling the Open Source Community
OPEN is a first of its kind, foundational blockchain technology, using Kotlin to accomplish a nominal rate of 1,500 transactions/second. This speed allows companies in various industries to utilize a decentralized solution with a high throughput capability. Early adopters from the supply chain and healthcare to financial verticals are forking off of OPEN for their infrastructural needs.

OPEN was built with scalability, interoperability, and transparency in mind from the start; this includes architecture, integrations with other chains, and choice of language to execute smart contracts. Utilizing Kotlin as the language of choice translates into powerful out-of-the-box virtual machine bytecode that enables more developers to use their knowledge and experience with the JVM, a widely accepted family of languages. All the source code is a property of the Open Source community and, from day one, was committed into a public repository which can be seen on Github.
Record-breaking Speeds
High Throughput
Zensoft partnered with OPEN to build a Blockchain from scratch using Kotlin and based on DPoS (Decentralized Proof of Stake) based consensus protocol. Unlike Ethereum or Bitcoin, which can process up to 10 transactions per second, our team reached up to 1,500 transactions per second in the TestNet environment. This dramatic increase in speed empowers the OPEN platform to dominate the market with its unprecedented throughput speed.

Built from Scratch
The fork-worthy OPEN Chain implements an improved version of the DPoS consensus algorithm and of BIP 32 specifications (hierarchical wallets) and BIP 39 (access to the wallets using a mnemonic phrase), all of which were implemented from scratch by our experts. During development, pre-planned design elements were put into place in consideration future functionality, such as the storage of alternative tokens (assets) and smart contracts.

Kotlin Virtual Machine
The OPEN Chain architecture was designed with smart contracts in mind. The implementation of smart contracts is taken into account in the design at a basic level, saving future developers excessive efforts in development and implementation. The obvious advantages are Java Virtual Machine and the abundance of support for the languages chosen.
OPEN chain implements DPoS-based consensus, but with some improvements that help to prevent the occurrence of side chains, and to guarantee less vulnerability to malicious attacks. This is achieved by implementing a solution to the Byzantine Generals (BFT) problem.
