Holoworld (AVA): Bringing Imagination to Reality With AI

Kaia (KAIA) unites Klaytn & Finschia for Asia’s web3 growth. Backed by KakaoTalk & LINE, it offers scalability, low fees, & bridges Web 2.0 to web3.

 (TON) in 2024, largely attributable to its Telegram-based mini 

 (DApps), has put the spotlight on the use of 

 technologies in instant messaging platforms. However, the Telegram-linked project isn't the only one that has identified the potential in this area. As early as February 2024, two blockchain platforms with links to popular Asian messaging networks announced their high-profile merger. 

The merger of Klaytn (KLAY) — backed by the South Korean instant messaging platform KakaoTalk — and Finschia (FNSA) — operated by the owner of the Japan-based LINE messaging app — may have a far-reaching impact on the entire crypto industry. The merged entity, branded Kaia (KAIA), aims to become the leading web3 platform in Asia. With its deep links to Web 2.0 messaging giants, the Kaia blockchain could also challenge the dominance of TON in the niche of messenger-based mini DApps.

Kaia’s faith in its ambitious plans is well-founded. The KakaoTalk and LINE messenger apps boast a combined user audience of nearly 300 million across several Asian countries. With the vast number of easily accessible target users, Kaia is ideally positioned to become the main bridge between Web 2.0–based online messaging and web3. However, the multimillion army of potential users on KakaoTalk and LINE isn't the only trump card of the Kaia project: the blockchain features great scalability, near-instant finality, excellent throughput capacity and low transaction costs. 

With all of these benefits on offer and backing from some of the most prominent players in Asia's instant messaging sector, the Kaia chain might become the crypto industry's up-and-coming growth leader for the year 2025.

 (KAIA) is a Layer 1 blockchain that has emerged due to the merger of two web3 platforms — the Klaytn and Finschia blockchains. 

Klaytn and Finschia had operated as separate networks for several years, Klaytn since 2019 and Finschia since 2018, before their governance communities voted in February 2024 to approve the merger. The Kaia 

The merger immediately attracted the attention of industry observers, as it involved two platforms backed by Asian instant messaging giants — South Korea’s Kakao Corporation, the developer of Klaytn and KakaoTalk instant messenger, and Japanese LY Corporation (previously Line Corporation), the entity behind the LINE messenger app and the Finschia blockchain. As of early 2025, KakaoTalk boasts over 50 million active monthly users, mostly in South Korea, while the LINE messenger has around 230 million active monthly users spread across its key markets — Japan, Indonesia, Taiwan and Thailand.

The sheer size of the combined user audience of KakaoTalk and LINE, and their connection to the newly formed Kaia blockchain, suggest the project may become a leading platform by integrating web3 functionality into both messengers, similar to the way TON’s chain has become a champion of Telegram-based mini DApps. However, the goals of the merged project go well beyond the integration of Web 2.0 messaging and web3 functionality, and the Kaia project hopes to leverage its potential reach to become Asia’s leading blockchain platform.

 (EVM)–compatible blockchain that boasts outstanding technical properties, including one-second block generation times, a throughput capacity of 4,000 

 (TPS) and near-instant finality. It also offers low transaction fees (1/10th of Ethereum’s fees).

 of the original Klaytn blockchain. Following the merger, Klaytn's testnet, Baobab, has become Kaia’s testnet under the new name of Kairos.

Aiming to become the largest web3 environment in Asia, Kaia offers decentralized projects and developers opportunities across a wide variety of sectors, with a particular focus on three niches — 

Transition From Klaytn and Finschia to Kaia

The original Klaytn blockchain was launched in June 2019 by GroundX, a subsidiary of the South Korean technology giant Kakao Corporation. The key aim of Klaytn was to provide a low-

, high-throughput, developer-friendly platform for enterprise-grade applications. Klaytn was forked from Ethereum, and was highly EVM-compatible. It quickly grew popular in the South Korean market, propped up by support from the powerful Kakao Corporation.

Soon after its launch, the blockchain became the dominant web3 platform in South Korea. In 2021, the Bank of Korea selected Klaytn as the provider of choice for its 

 (CBDC) project. Kaia's great technical capabilities primarily derive from the original Klaytn network.

As for Finschia, the origins of this platform go back even further, to 2018, when Japan’s LINE Corporation — now known as LY Corporation, after a merger of several related business entities — developed and launched the LINK blockchain. In 2020, the platform was rebranded from LINK Chain to LINE Blockchain. This wasn't the last name change in its history, as the project’s penchant for rebranding proved unstoppable. Three years later, in April 2023, LINE was rebranded to Finschia.

The Finschia chain aimed to accommodate a wide variety of use cases, sporting an ambitious motto —

In January 2024, a proposal to merge Klaytn and Finschia was tendered for consideration by the platforms’ governance communities. One key aim of this proposed merger was to combine the potential reach of the two chains in Asia (estimated at around 250 million users for the two messenger apps at that time) in order to create the continent’s largest web3 environment.

The proposal was approved in February 2024 with overwhelming support, with 90% of Klaytn and 95% of Finschia governance representatives voting in favor of the merger.

In late August 2024, the Kaia mainnet launched, signifying the practical start of the ambitious project. As a fork of Klaytn, Kaia inherited its technical setup. This meant that DApps in the Klaytn ecosystem could seamlessly transition to the new network, with minimal modifications. Finschia DApps, on the other hand, need to be migrated to the new platform. Finschia Foundation, a nonprofit that supported the original Finschia project (and continues to provide support during the merger phase) can provide advice to DApps undertaking migration from the Finschia blockchain to Kaia.

The Kaia blockchain uses a specialized block validation process known as Practical Byzantine Fault Tolerance (PBFT). Distinct from 

 models employed in the industry, PBFT is a modification of the Istanbul BFT (IBFT) consensus algorithm, an innovative network consensus model designed to power secure block validation in distributed networks.

Kaia's PBFT algorithm randomly selects a committee of 

 to process and validate transaction blocks at one-second intervals. One validator node in the committee is assigned the proposer role. This node generates and proposes a transaction block for validation. The committee’s members need to sign the block to endorse its validity. In order for a block to be validated and written to Kaia's permanent ledger, more than two-thirds of the committee members must approve it. The committee isn't fixed, and a new one is formed from the pool of validator nodes for each block to be processed. Given Kaia's one-second block intervals, this committee selection process takes place every second.

Kaia's PBFT is designed to reliably process transaction blocks even when some proportion of validators on the network act maliciously. As such, PBFT is a highly fault-tolerant consensus model, a property it inherited from the original IBFT algorithm.

 (DLT) employs a three-layer architecture to power the network's operations. The underlying consensus layer is made up of consensus nodes (CNs), whose job is to process and approve blocks of transactions. These are the validator nodes we discussed above in the context of Kaia's PBFT consensus algorithm.

Above the consensus layer is the proxy layer, which is made up of core cells — mini networks consisting of one CN and two proxy nodes (PNs). PNs serve as an interface linking the underlying and outer layers of the blockchain. Within each core cell, a trio of one CN and two PNs work together to receive data from the outer layer and process transaction blocks.

This outer layer consists of endpoint nodes (ENs) that process data from service chains — app-specific Kaia chains that can be customized for the needs of each application or service.

The image below summarizes Kaia’s three-layer architecture, showing the three layers and the node types operating on each of them.

Kaia is an EVM-compatible chain capable of 

. The Kaia Virtual Machine (KVM) powers smart contracts and their processing on the network. KVM is derived from Ethereum’s virtual engine, the EVM, so blockchain developers can easily port Ethereum applications to Kaia with little modification. Common development technologies used in the Ethereum environment — such as the Solidity programming language, and the Hardhat development framework — are available to blockchain programmers building Kaia-based DApps.

The Kaia Governance Council, a group of reputable organizations in the blockchain industry, carries out the platform's governance. Council members consider proposals submitted by advisors and other stakeholders, analyze the proposed changes and vote to decide on them. While the Council currently drives the platform's governance process, Kaia aims to eventually fully decentralize its decision-making structure by introducing a community-based 

 (DAO). This will provide a more democratized and inclusive way for the wider user community to have a say in the network's strategic direction and rules.

Kaia uses an account-based model similar to the one employed by Ethereum, as opposed to the 

 (UTXO) model commonly associated with the Bitcoin (BTC) blockchain. However, the similarities between Ethereum’s and Kaia's account structures end here. 

One distinct feature of Kaia accounts is the ability for users to generate multiple key pairs. On most other blockchains, including Ethereum, an 

 can be associated with only one public-private key pair. This has several disadvantages, the most relevant of which is reduced security. By allowing multiple key pairs for account addresses, Kaia improves the overall security of account management for ordinary users and smart contract owners alike.

Each key pair generated for the address can be assigned a specific purpose or role. These role-based keys essentially mimic the functionality offered by 

, further enhancing account security and enabling more flexible access control modes.

There are two types of Kaia accounts: externally owned accounts (EOAs), which are used for cryptocurrency storage and transfers, and smart contract accounts (SCAs), which are capable of processing and storing smart contract code. While DApps leverage SCAs to power their functionality, most individual crypto users choose EOAs.

To make the management of EOAs easier and more user-friendly, the project team has developed a native wallet solution for the blockchain, Kaia Wallet, which operates as a browser extension. Available for Google Chrome, Kaia Wallet lets you manage your account via the familiar web-based interface.

The platform also offers a solution for multisig accounts, 

, which may better suit the needs of institutional users with sophisticated access control requirements.

A novel feature built into Kaia accounts is fee delegation, the ability for a user to send KAIA, the network's native token, without having to cover the transaction fee. Instead, the sender requests in the message that the fee is to be covered by the recipient party. The platform even supports partial fee delegation, whereby the sender can stipulate a specific proportion of the fee to be covered by the receiver.

The fee delegation feature may be used for multiple transaction types, involving both EOAs and SCAs.

KAIA is the Kaia platform's native cryptocurrency. It represents a rebrand of Klaytn's native token, KLAY. Following the Klaytn and Finschia merger, all KLAY tokens on the network were transferred automatically to the new KAIA tokens. For Finschia's FNSA token holders, the procedure to convert to KAIA is a bit more involved. They can utilize the Kaia Portal to 

 their FNSA tokens held on the Finschia chain, and then claim the equivalent amount of KAIA on the new blockchain.

KAIA is used to pay for smart contract operations on the network and 

 for transactions. It also has some staking functionality built in. Organizations admitted to the Kaia Governance Council need to stake at least 5 million KAIA to join.

The token is also used to pay block validation rewards. Earlier, we described a procedure involving node committees that process transaction blocks on the Kaia chain. For each generated block, 9.6 KAIA is split between the committee members involved in validating that block and two critical funds on the platform — the Kaia Ecosystem Fund (KEF) and the Kaia Infrastructure Fund (KIF). The validator committee members earn 50% of the block reward, while KEF and KIF receive 25% each.

KAIA’s total supply as of Jan 13, 2025 stands at nearly 5.9 billion. Since the token is continually issued for block rewards, its supply is subject to inflation and has no maximum cap.

As of Jan 13, 2025, the KAIA token is trading at $0.209, which is 48.9% lower than its ATH of $0.4067 on Dec 3, 2024, and 83.7% higher than its ATL of $0.1131 on Nov 4, 2024.

Long-term price forecasts for KAIA are generally bullish.DigitalCoinPrice 

 of $0.72 in 2027 and $1.12 in 2030, whileCoinCodex 

 at $ 0.2178 in 2027 and $ 0.68 in 2030.

The merger of Klaytn and Finschia has produced an enormously influential platform with potential access to nearly 300 million users of KakaoTalk and LINE. Moreover, this multimillion-strong potential audience isn't the only source of users that Kaia could tap into. Offering outstanding scalability, a highly secure consensus mechanism, low transaction costs and a unique account model capable of handling multiple key pairs per address, the Kaia blockchain is ripe for adoption by the enterprise world.

As of the start of 2025, the merged chain is still in the early months of its operation. While it might be a bit early to declare Kaia as the next big thing in the 

, the project is quickly shaping up as one of the best candidates for that designation, at least in the vast expanse of the Asian continent.

Privacy and security have always been a ground for debates in the crypto industry. Hence, the foundation of a consensus mechanism in the

So, to help you understand the differences between Proof of Stake and Proof of Work better, we’ll be highlighting the dissimilarities. That includes the mining mechanism, transaction verifications, safety, and more.

 is an upgraded consensus algorithm primarily to solve problems the current Proof-of-Work is facing, including high electricity costs and security issues. Though both of these algorithms strive to solve the same problem, the process of reaching the goal is relatively different. 

The introduction of PoS is to eradicate the 

. As compared to Bitcoin’s PoW consensus, the PoS aims to stray away from the dependency on computer power to form a well-defined sequence of blocks. So, instead of miners competing against each other to complete a transaction on the network, there won’t be any competition to cherry-pick a person to add blocks.

Ultimately, PoS replace miners with validators to lock up a stake within a crypto ecosystem. Hence, these blocks are referred to as minted rather than mined.

 (DPoS) is a contemporary consensus mechanism to improve scalability without compromising the incentive structure built on the blockchain. Unlike the conventional PoS mechanism, DPoS allows users to earn rewards and rights for validating a transaction, putting blocks together, through coins staking.

So, if a user fails to verify a transaction, the block will be missed, and the reward is then accumulated for the next witness. In the end, the DPoS strives to boost the overall mechanism’s efficiency and build a more coherent ecosystem. 

The PoS algorithm is conceptualized based on the arbitrary election processes to select a node as a validator for the next block. Unlike PoW, there won’t be any mathematical puzzles to solve to validate a block in exchange for rewards. Hence, mitigating the energy-intensive mining process.

On the contrary, the PoS system rewards the validators through a transaction fee. So, a user who participates in the forging process by staking a certain amount of coins into the network may get a chance to be picked for forging the next block. For example, if one participant staked five coins while someone else staked 50 coins; naturally, the chosen next block validator is always those with a higher total value staked. In the end, the more you stake, the higher chances you’ll be selected to be the next validator. 

However, the PoS consensus is criticized for its favoritism towards the wealthy. The most affluent will likely be selected by the system, whereas the poor will be discriminated against. Of course, this methodology 

 concerning the partiality led by an unjust system. Hence, the randomized block selection, a coin age selection, and fisherman system came into play to circumvent the flaws.

Here’s the breakdown of these unique integrations:

This methodology offers a sophisticated logic by combining the lowest hash value on a node with the largest stake size. The randomization helps regulate a healthy ecosystem within the PoS consensus and protect valuable block-forger that appends blockchain blocks.

On the other hand, this selection method relies on the period of the cryptocurrency has been staked. This methodology aims to provide an impartial PoS consensus and prevent the domination of larger staked nodes on the blockchain. That means whenever a node forges a block, the coin age will reset to zero, and there will be a cool-down period to forge a block again. 

Here’s how you calculate the coin age cool-down time:

For example, if you’ve staked only one coin for 20 days, the coin age is 20, and it’ll reset to zero until you can forge another block again.

The rules are different depending on each of the cryptocurrency using the Proof of Stake algorithm. Well, the fisherman approach is here to mitigate malicious activities against the validators. When a validator possessed a threat to the network, the validators could risk losing their funds. Besides, the validator can also be blacklisted from being a validator ever again.

However, if nodes decide to stop being a forger, they can withdraw all of the rewards and stakes. That means all of the blocks must be verified and confirm no engagement in any fraudulent activities.

This consensus mechanism was introduced by Satoshi Nakamoto alongside Bitcoin in a 

 back in 2008. As a fault-tolerance solution, PoW is used as a cryptocurrency protocol for generating new blocks while maintaining the network through the mining process. In exchange for rewards, miners need to maintain the network by solving intricate cryptographic problems. 

The implementation of PoW aims to decentralize transactions and to eradicate the possibility of double spend aka 51% attack. However, the occurrence remains inevitable. In fact, the attack has happened to 

multiple times. On top of that, the use of PoW is rather energy-consuming. To add on, the mining hardware for mining is relatively expensive to maintain the system. Hence, the scalability of this setup is questionable. 

Miners use the PoW protocol in the mining process. So, when someone send a Bitcoin from one to another, a block with a timestamp on the decentralized network will record the transaction. To validate the transaction, miners need to deploy computing power (

) to solve complex mathematical puzzles. To uphold the consensus, the majority of nodes have to agree that the problems have been solved. 

Proof of Stake vs. Proof of Work: The Differences

Today, blockchain technology is revered for being secure. But it doesn’t happen without the significant functions of the consensus mechanism. While both PoS and PoW are devised to tackle the blockchain hacks and frauds, they deviate from one another.

Here’s an overview of its differences: 

The Proof of Stake system is more efficient when comparing it with the PoW mining system. That’s because PoS does not require mining while miners require a colossal of energy to mine a PoW based cryptocurrency like Bitcoin.

With PoS, the mining power is distributed proportionally to the coins a miner holds. It is thereby limiting the mining percentage of a transaction through the ownership of a miner’s stake. So, let’s say a miner staked 10% of Bitcoin, the maximum blocks can be mined is capped at 10%. 

Bitcoin has always been the center of attention, including the energy it consumed. With Bitcoin’s PoW system using almost 0.21% of the world’s energy supply, Bitcoin mining is the least environmentally friendly digital asset. Besides, the competitive nature of Bitcoin mining means more computing power is required to sustain the ecosystem.

With the PoS system’s implementation, mining can be replaced with a minimal amount of energy to maintain the system. The upshot? The environment is restored, and the scalability is upheld via community involvement. 

The risk of centralization is one of the biggest concerns with the Proof of Work consensus algorithm. Since the PoW mining system is much more reserved for the majorities, this system’s transparency is obscured for the community. When PoW relies only on the majority, it’s moving towards the idea of centralization by granting the possibility of a network or transaction manipulation. 

Proof of Stake, on the other hand, provides a fairer solution through the distribution of authority within the holders and stakers. That means the network control is proportional to how much a participant invests. For example, participant A in PoS invests in 20 coins, and he’ll receive the same amount of power.

However, the same participant invests in 20 coins more than participant B; he’ll be receiving more computation power. As a result, PoS is more transparent since the network is more rigid as compared to PoW.

Proof of work on Bitcoin may be resilient to a specific attack. But it is vulnerable to potential security risks, including a 51% attack and system instability due to forking.

When a fork happens on a blockchain, the 

. Let’s say a blockchain is forked; miners would need to direct their mining power to the old and newly forked blockchain. Of course, hard-fork means to bring goods rather than harm. Still, splitting the mining power reduces a miner’s crypto mining rate.

However, Proof of Stake is more resilient towards a 51% attack. That’s because it’s even more expensive to execute this malicious attack on the PoS. Though it’s not entirely impossible, as long as the attackers can bear the drastically increased crypto price and gather enough power in a short amount of time.

Both the PoW and PoS reward cryptocurrency to the participants who can propose a valid block. However, the PoS system’s reward is proportional to how much a participant stake as collateral to verify a transaction. Still, the size and how long the crypto has been staked play a role in determining who gets to verify a transaction first.

Proof of Stake vs. Proof of Work: The Benefits 

Both of these consensus mechanisms are essential for blockchain. Still, the benefits are different, especially since both of these mechanisms serve another purpose. 

The PoS mechanism is beneficial for the environment as it is less reliant on electricity. Higher collateral requirements and heavier punishments towards a faulty block on PoS also result in a healthier ecosystem, and it’s more sustainable in the long-term. It also offers a fairer mining system with scalable transactions as compared with the PoW. Best of all? PoS steers away from the centralization idea by focusing on an individual’s coin ownership for control delegation.

Proof of Stake vs. Proof of Work: The Risks

Many cryptos are still using the Proof of Work consensus, including the titan Bitcoin and Ethereum. However, the Proof of Stake algorithm appears to be safer. That is because it’ll be even more costly to attack a transaction on PoS when comparing to PoW.

In fact, Ethereum 2.0 will be ready to launch with the Proof of Stake model wherein miners are referred to as block validators. Hence, providing a safe blockchain ecosystem for miners and investors. 

The majority of cryptocurrencies today are still using the Proof of Work algorithm, including Bitcoin. However, many cryptocurrencies are transitioning to the Proof of Stake algorithm. That gives different economic benefits to HODLers to run a master node or staking coins in exchange for rewards. Here are some of the cryptocurrencies that are using the PoS mechanism:

: The first Chinese open-source blockchain project allows more than one crypto-token to stake in NEO wallet. Participants earn rewards in the form of NeoGAS with approximately a 2% to 3% annual return rate.

: Staking STRAT in a Stratis wallet can earn you rewards with around 0.5% to 1% annual return rate.
