TBD, a division of the financial-technology company, Block, has launched “c=” (pronounced “c equals”), a new business entity focused on improving liquidity and routing on the Lightning Network, Bitcoin’s layer 2 scaling system.

Lightning transactions are at an all-time high but, according to a release provided to CoinDesk, the network is experiencing growing pains with many transactions failing due to poor liquidity and inefficient payment routing.

C= will address these issues by committing bitcoin to the Lightning Network and building infrastructure to bolster network reliability.

“Connecting to the Lightning Network requires liquidity in the form of bitcoin,” the release states. “C= will build infrastructure using the bitcoin it is committing to the network so that businesses and wallets can make their Lightning transactions more reliable and dependable.”

Block's head, chairman and co-founder is Jack Dorsey, who previously was co-founder and CEO of Twitter.
