Staking, the process of locking native blockchain tokens to secure the network and receive rewards, has become a major business line for centralized exchanges looking to diversify their revenue streams away from transaction fees. Coinbase is the second-largest ETH staker, though competitors like Kraken and Binance have moved into the business. In many ways, if the SEC is successful in banning staking programs, decentralized alternatives like Lido and RocketPool, the largest and third largest ETH-based platforms by value, will benefit.
