Jack Dorsey's Block Launches Service Provider to Make Lightning More Reliable
The new entity dubbed “c=” aims to improve liquidity and routing on Bitcoin’s Lightning Network. The name references the speed of light in Einstein's famous equation E=MC2.
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.

KuCoin Hits Record Market Share as 2025 Volumes Outpace Crypto Market

KuCoin captured a record share of centralised exchange volume in 2025, with more than $1.25tn traded as its volumes grew faster than the wider crypto market.
What to know:
- KuCoin recorded over $1.25 trillion in total trading volume in 2025, equivalent to an average of roughly $114 billion per month, marking its strongest year on record.
- This performance translated into an all-time high share of centralised exchange volume, as KuCoin’s activity expanded faster than aggregate CEX volumes, which slowed during periods of lower market volatility.
- Spot and derivatives volumes were evenly split, each exceeding $500 billion for the year, signalling broad-based usage rather than reliance on a single product line.
- Altcoins accounted for the majority of trading activity, reinforcing KuCoin’s role as a primary liquidity venue beyond BTC and ETH at a time when majors saw more muted turnover.
- Even as overall crypto volumes softened mid-year, KuCoin maintained elevated baseline activity, indicating structurally higher user engagement rather than short-lived volume spikes.
