Coinbase CEO Brian Armstrong says the crypto exchange will indeed add support for the Lightning Network, one of the biggest endorsements yet for the blockchain that makes bitcoin (BTC) a more realistic option for payments by dramatically speeding up transactions.

Lightning is a layer-2 blockchain associated with the Bitcoin blockchain. Bitcoin transactions can be offloaded there for more efficient – and much faster – processing, a prerequisite if BTC has a shot at eventually becoming a common method of payment.

“Bitcoin is the world’s digital monetary system, and Lightning is Bitcoin’s payments layer,” Cathie Wood, the head of Coinbase’s second-biggest shareholder, ARK Invest, wrote on X in response to Armstrong’s post Wednesday. “Coinbase’s integration with Lightning will give its 100 million users an on-ramp to faster and cheaper bitcoin transactions. Hats off to Coinbase!”
