Kaia's native token, KAIA, serves as the foundational asset of its Layer 1 blockchain, which was established through the merger of Kakao's Klaytn and LINE's Finschia networks. Designed to integrate Web3 functionalities into widely used Asian messaging platforms, KAIA facilitates transaction fees, smart contract executions, staking, and governance within the ecosystem. The token's distribution model includes an initial annual inflation rate of 5.2%, with block rewards allocated as follows: 50% to validators and the community, 25% to the Kaia Ecosystem Fund (KEF), and 25% to the Kaia Infrastructure Fund (KIF).

Ethereum (ETH) is a decentralized blockchain platform that enables developers to build and deploy smart contracts and decentralized applications, providing them with a secure and scalable infrastructure. It operates on its native cryptocurrency called ether, used by participants to transact and incentivize network operations.

Ethereum stands out for its ability to support smart contracts, which are written into code and stored on the Ethereum blockchain. These contracts eliminate the need for intermediaries or third parties, as pre-defined actions are carried out when they are triggered. This sets Ethereum apart from other cryptocurrencies and traditional financial systems. Smart contracts on Ethereum have diverse applications, automating processes like financial transactions, supply chain management, and voting systems. For instance, a rental agreement stored as a smart contract could transfer payment from a tenant to a landlord on the specified due date, without manual intervention or reliance on a trusted third party.

The execution of smart contracts on Ethereum brings transparency and immutability to the network. Once deployed, these contracts cannot be altered or tampered with due to the decentralized nature of the blockchain. This ensures that the agreed-upon terms and conditions are followed without any potential for manipulation or fraud. Since the contract is visible to all participants on the Ethereum network, it promotes transparency and trust, allowing independent verification of the contract's execution and outcome. Ethereum's smart contract feature revolutionizes the way agreements and transactions are conducted, eliminating intermediaries, automating processes, and ensuring transparency and immutability. This functionality opens up a world of possibilities for decentralized applications and contributes to a more efficient and secure financial system.
