Founded in 2012, Coinbase used to just be a simple market to buy and sell Bitcoin. A lot has changed since, and the decade-old firm is working to keep up with the times. Last month, Coinbase announced the launch of its native layer-2 scaling solution called Base. It’s built using the OP Stack, which is to say the new product is using a lot of Optimism technology. It’s an interesting play, especially for a highly-centralized, highly-regulated, publicly traded company in the United States.
