Again a strong Potential defi and very interesting cross-chain project linked to Polkadot:
here the description :
RING is the native token of Darwinia Network. It's used to pay for the GAS fee of the on-chain transactions and cross-chain services. RING can be staked for staking rewards and obtaining voting power to participate in the governance.
Darwinia Network is a decentralized heterogeneous cross-chain bridge protocol built on Substrate, serves as critical infrastructure for interoperability across the blockchain networks. Darwinia Network focuses on decentralized cross-chain token swap, exchange, and market and enables single-chain application upgrade to cross-chain version, including Defi, Game, DEX, NFT market, and more. Its vision is to build the future Internet of Tokens.
So to be clear and fast , Darwinia will connect all Blockchains, Kton is a reward for stacking RING, Kton + Darwinia Stacking = more power in your stack = more rewards.
