Coinbase is the second major centralized exchange after Bitfinex, which has announced plans to withdraw some of its transactions from the main Ethereum blockchain. Bitfinex is in the process of integrating the OMG Network based on the More Viable Plasma (MoreVP) specifications. Plasma is another concept for increasing Ethereum throughput by creating an additional second layer network. Earlier, Vitalik Buterin, the co-founder of the second largest cryptocurrency by capitalization, said that only the transition to second-level solutions will create the preconditions for reducing the cost of transactions.
