Yes, it is true that Klaytn is the first and largest example in which the incentives supporting the ecosystem are encoded in an on-chain protocol tokenomics. As mentioned in the Klaytn 2.0 Light Paper, Klaytn has committed to support Ethereum Equivalence and has committed to a 66% support rate for the same. Staking in this platform is indeed very rewarding for both developers and investors alike. Not only does it offer a very good APY, but it also provides a wide range of incentives for Klay holders and blockchain users, making it a great choice for anyone looking to get involved in the blockchain space.
