With decentralized finance (DeFi) evolving rapidly, several projects have emerged under the DeFi 2.0 umbrella, aiming to resolve scalability, sustainability, and adoption issues. This report examines four leading DeFi 2.0 projects Kadena, Uquid Coin, Alchemix, and KlimaDAO each offering unique contributions to the sector.

Kadena(KDA): Multi-Chain Proof-of-Work Innovation

Kadena combines proof-of-work (PoW) consensus with directed acyclic graph (DAG) principles to enhance throughput and scalability. It operates through a braided multi-chain structure, currently supporting 20 parallel blockchains. This allows the network to validate transactions simultaneously while maintaining high security standards. Kadena's infrastructure is energy-efficient and supports features such as crypto gas stations, enabling businesses to cover gas fees for their customers. While scalability is theoretically unlimited, network expansion requires a hard fork, contingent on user adoption.

It supports staking, governance and payments, particularly on the Uquid Shop, which offers over 40,000 digital products. Through the integration of DeFi tools such as Defito, Uquid enables automated processes like shopping mining, providing liquidity to virtual goods. The platform also uses smart contracts to reduce intermediaries and enhance efficiency in digital and future physical goods markets.
