Jack Dorsey’s digital payment company Block Inc. said it will be using its own Bitcoin reserves to provide liquidity to Bitcoin’s Lightning Network, a protocol meant to make transactions on the blockchain more efficient. 

TBD, the Bitcoin-focused unit of Block, plans to launch a so-called Lightning Service Provider named c=, hoping to reduce failed transactions on the Lightning Network stemming from a lack of liquidity. 

The Lightning Network, built on top of the Bitcoin blockchain, enables users to send and receive payments faster and for less money than processing a transaction directly on Bitcoin’s blockchain.
