Dorsey Backs Lightning Labs for Faster Bitcoin Transactions

Lightning Labs announced it had raised $2.5 million and at the same time released a beta version of their technology; one of the criticisms of bitcoin is that it can handle a limited number of transactions per second; some believe that bitcoin should increase its block size to process more transactions; Lightning Labs is working on the Lightning Network to add another layer of transactions to sit on top of the blockchain network which would allow for more transactions to take place.
