TBD, a division of Block (formerly Square) led by CEO Jack Dorsey, launched a new venture named c= (pronounced c equals) to improve the Bitcoin Lightning Network through tools and services.
The Lightning Network (LN) is a layer 2 payment network built to ease the mainstream adoption of Bitcoin (BTC) by enabling faster, cheaper and more reliable peer-to-peer payments. However, c= aims to further the reach of LN through added liquidity and routing services.
