Liquid staking is become more popular as Ethereum, the second-largest blockchain, proceeds toward becoming a proof-of-stake (PoS) system. Coinbase, the U.S. publicly traded crypto exchange, said last week it plans to offer its own liquid staking token, called Coinbase Wrapped Staked ETH (cbETH). It joins Lido Finance, which said in July it would soon offer staked ether on layer 2, or companion, networks.
