We as a Klaytn development company can help you build highly scalable dApps for business. If you are interested in exploiting the potential of Klaytn blockchain that is designed for the metaverse, gaming, and dApps.

Klaytn is one of the best blockchain platforms. Blockchain is uniquely changing the world. How we store, access, and use data is now changing to make the never-ending cycle of technological advancement better. Blockchain is helping businesses, governments, and other organizations better manage their workflows and improve their systems by providing better solutions. It also affects other components of our technology, such as how we trust the network.

There are different methods of blockchain control: private, public, consortium, and hybrid. Hybrid blockchains combine the advantages of a private and public blockchain. Instead of changing their goals due to technical limitations, it gives companies more control over what they want to achieve. Hybrid blockchains have the best features to combine the best features of both private and public blockchain systems. In an ideal situation, a hybrid blockchain would provide both controlled access and freedom. Hybrid blockchain architecture differs from other blockchain architectures in that it is not available to everyone but still provides blockchain benefits such as integrity, transparency, and security.

Blockchain technology can be used both financially and in other industries. It is difficult to manipulate data or hack into the system using blockchain. The openness of the public blockchain unites individuals from around the world, but the private blockchain guarantees that a closed ecosystem can also benefit from the power of the blockchain. The Klaytn platform is one of the latest hybrid blockchains to emerge. Klaytn is a hybrid blockchain ecosystem for businesses that address a variety of service-related concerns. Let's take a closer look at Klaytn and how it works. The sections on this page will provide an overview of Klaytn, its components, and prospects for developing Klaytn. Klaytn's enterprise-friendly ecosystem.

The Klaytn Foundation is a non-profit organization in Singapore founded to accelerate the sustainable growth of Klaytn. The Klaytn Foundation supports developers to strengthen the technology of the Klaytn network. The Klaytn Foundation facilitates businesses to participate in Klaytn's global ecosystem. The Klaytn Foundation coordinates to create value from their interactions with developers, businesses, and communities. To fulfill this role, the Klaytn Foundation runs open grant activities, including the Klaytn Growth Fund (KGF) and the Klaytn Improvement Reserve (KIR).

What is Klaytn Network?

Klaytn, Kakao's global public blockchain initiative, is an enterprise-grade, service-centric platform that provides millions of people with a user-friendly blockchain experience. An efficient 'hybrid' architecture combines the best features of public (decentralized data and control, distributed governance) and private (low latency, high scalability) blockchain. Klaytn is protected by a number of well-known businesses worldwide who have collaborated to build a secure business platform based on a decentralized trust system. Klaytn is a blockchain-based platform that enables companies and entrepreneurs to get value now. GroundX created Klaytn as a blockchain for the future.

In Klaytn's view, blockchain applications (BApps) are considered first-class citizens. They strive to deliver the best level of performance and productivity in an environment that appeals to a wide range of engineering audiences, from micro startups to large corporations. DApp support will be released with complete developer tools for software development to give the best experience for their customers. Thanks to a combination of Klaytn features such as low-latency network responsiveness, reliable yet robust transaction throughput, flexible scalability through service chains, and transaction fee subsidies for end users. Furthermore, the simple integration of Klaytn networks with conventional corporate assets (through enterprise proxies) provides a quick onramp for parties seeking to add blockchain capabilities to their existing products.

Klaytn Foundation and Service Partner

Klaytn is a global public blockchain platform developed by Ground X, a blockchain subsidiary of South Korean social media company Kakao. Klaytn, a blockchain developed by Kakao, was built with modular network architecture, making it an attractive business blockchain alternative. Its modular network architecture makes it easy for enterprises to build and operate service-based blockchains based on Clayton architecture. Service chains are autonomous sub-networks that form the backbone of Klaytn's enterprise-friendly environment. Due to the flexibility and customization of this service chain, any online service can be built on Klaytn. However, initiatives based on gambling or financial speculation are not permitted.

Klaytn's Mainnet was launched in June 2019 and immediately attracted more than 40 primary service partners and all partners (ISPs) across a wide range of sectors and uses, including entertainment, e-commerce, healthcare, and finance. These ISPs come from a variety of countries and have been selected for the quality of their blockchain-based services and the size of their current user base. Humanscale, a data marketplace for patient-generated health data; Atlas, blockchain-based travel content and transaction platform built by Chinese luxury travel business Zanadu; And REDi, a blockchain-based market for innovative and sustainable energy; All examples of ISPs so far.

Separate promotional channels for blocks and transactions (multichannel promotions)

The latency of a network is greatly affected by its level of congestion Assuming the network throughput is constant, increasing the number of transactions will delay the latency of the network proportionately. Latency delay is a complex issue in DApps; Ordinary users of legacy mobile apps or web services will not tolerate responses that take more than a few seconds, and there is no reason to overestimate user tolerance on blockchain services.

Klaytn adopts a multichannel approach to handle network congestion issues. By allocating separate promotion channels for transactions and blocks, the Klaytn network can promote newly created blocks promptly even when the network is facing heavy traffic congestion with lots of transactions. In this way, Klaytn ensures that DApps on its network can respond to end-user requests regardless of uninterrupted network traffic spikes.


What is the purpose of Klaytn Network?

Klaytn is a BFT-based public blockchain with excellent performance and enterprise-grade reliability. The following important design objectives:

  • Termination immediately.
  • TPS is high enough for real-world use.
  • Reduce the cost of developing and running blockchain applications.
  • Reduce entry barriers for end consumers.
  • Facilitate the acceptance of new technologies in the industry.


What are the basic features of the Klaytn method?

On June 27, 2019, Klaytn released its Mainnet Cypress with the following features:

  • Block Generation and Confirmation takes one second.
  • Four thousand transactions per second are possible.
  • Gas is about one-tenth of the price of Ethereum.
  • Supports solidity contract execution by running EVM

The Klaytn Governance Council was founded by 19 reputable businesses worldwide to run consent nodes. Klaytnscope displays the current number of consent nodes. At Klaytn, more than 50 first service partners are committed to launching blockchain applications.


What are the three distinct logical subnetworks of Klaytn?

According to the functions and goals listed below, Klaytn is divided into three logical subnetworks.

Network of Core Cells (CCN)

CCN's core cells (CCs) verify and execute transactions provided by endpoint nodes (ENs). CCN is responsible for creating and distributing blocks across the network.

Endpoint Node Network (ENN)

ENN is responsible for creating endpoint node (ENs) transactions, handling RPC API calls, and processing data requests from the service chain.

Network of Service Chain (SCN)

SCN is a Klaytn subnetwork made up of supportive blockchains run independently by blockchain apps (BApps). Klaytn consists of the main chain, or manner, core cell network, and endpoint node network. Blockchain applications can run on Klaytn main chains, Cypress, or their blockchains, known as service chains. ENs connect service chains to the main chain. Service chains are recommended if your application requires a dedicated execution environment with high TPS and customizable network rules.

How does Klaytn block create and promote?

The architecture and employed consensus approach to block creation and promotion all play a role in reducing the latency of a blockchain platform.

Block Generation Cycle:

In Klaytn, a 'circle' is a block creation cycle. Each round creates a new block, which is followed by the start of a new round. Klaytn aims for a one-second round time; However, network traffic and node operation status may change the interval between block formation.

Proposal and committee selection:

Klaytn randomly selects a consensus node (CN) as the proposer for the block but will be created in each round and then selects a group of CN as the committee for that round. Each CN uses a random number derived from the most recent block header to conduct a cryptographic operation, proving that the CN has been selected (or not) for this round. The size of the committee should be Byzantine-resistant; If CNN is small, all CNs (except proposers) can work on the committee.

Offer validity and block:

Once selected, the proposer transmits proof of round selection (i.e., a cryptographic proof verified by the proposer's public key) to all CNs. Afterward, the CNs selected as the committee for the given round respond to the proposer with proof of their selection, telling the proposer that the new block should be broadcast. The proposer then selects a group of transactions from his transaction pool and arranges them in a block. Finally, the proposing committee works to agree and finalize the newly established block. Klaytn wants to improve its consensus algorithm over time to gain more security and efficiency.

Propagation of Blocks:

For approval, a proposed block must be signed by more than two-thirds of the members of the committee. If the committee agrees, the new block is circulated to all CNs, and the consensus round is completed. Once the new block is broadcast on all CN, PNN provides block header and body data to ENN, so that the information of the newly generated block can be made available to all Klaytn network participants.

What is a multichannel promotion on Klaytn?

The level of traffic congestion in a network has a significant effect on its delay. Assuming that the throughput of the network remains constant, the latency of the network will be proportionately delayed as the number of transactions increases. Users of conventional mobile applications or web services will take no more than a few seconds of response time and there is no reason to expect a greater user tolerance of blockchain services.

To deal with network congestion, Klaytn uses a multichannel strategy. The Klaytn network defines separate promotion channels for transactions and blocks that can transmit newly generated blocks promptly, even when the network is crowded with many transactions. Klaytn assures that BApps can answer end-user questions on its network despite such scattered network traffic growth.

With multi-channel, a Klaytn node can be easily controlled. For example, nodes can be executed through multichannel configuration. For this, you need to set up two nodes for communication. Conversely, if a node is executed with a single-channel configuration, set up port one. If two multichannel nodes work to connect, a connection is made between the two ports. Otherwise, these nodes will use a port for communication. The flag "- multichannel" can be used to start a multichannel node. The figure below will help you understand multichannel architecture.

What are the different smart contract components of Klaytn?

Klaytn compatible token:

Klaytn Compatible Token (KCT) is a smart contract that follows a set of technical guidelines. Anyone wishing to issue a token on Klaytn must follow the criteria. In Klaytn, token values such as KIP7 and KIP17 are specified. Other KCTs can be made to meet special technical requirements.

Fungible Token Standard (KIP-7):

Tokens with homogeneity and divisibility are called fungi tokens. Since the value of each unit of the fungible token is the same, they can be exchanged. For example, the face value of each 1 note is the same. A high percentage of blockchain tokens are fungible because fungibility is an important feature of cryptocurrencies in most situations. The KIP-7 Token Standard can be used to integrate these features into smart contracts. KIP-7 loyal tokens use the following interface Please note that KIP-13 and KIP-14 must be used together. The wallet interface can be applied to the Wallet app.

Non-fungible token standard (KIP-17):

A non-fungible token (NFT) is a form of token that represents one of the unique assets. Each non-fungible token is unique and non-divisible, as the name implies. The non-fungibility of non-fungible tokens offers new asset digitizing frontiers. KIP-17 can be used to implement non-fungible tokens. A wallet interface can be used in the Wallet app.

The above points are the various smart contract elements that establish the relationship between the Solidarity Smart Contract Language and the Klaytn Platform. Let's understand that relationship in the section below.

Perseverance and Klaytn:

Solidarity is a contract-based, high-level, statically typed language for building smart contracts on the Ethereum platform. Although Solidarity was built with Ethereum in mind, it is wide enough to create smart deals with other blockchain platforms like Klaytn.

The Constantinople Ethereum Virtual Machine (EVM) version is officially compatible with Klaytn. Klaytn does not guarantee backward compatibility with other EVM versions. As a result, it is recommended to use the Constantinople Target option when compiling solidity programs.

When creating smart contracts for Klaytn, developers can use tools such as Remix (a browser-based IDE) and Truffle (a programming framework). The Klaytn team will make every effort to keep Ethereum's and Klaytn's development tools compatible. However, they may choose to provide Klaytn Smart Contract developers an upgraded or updated version of those tools if necessary.
