Lightning Network is one of the key upcoming technologies that will change Bitcoin for the better, it’s a network of nodes with channels between these nodes that process payments and transactions “off-chain”, to keep only the few important transactions on-chain and decrease the load on the blockchain and the time it takes to send a transaction.

However there is a potential for node centrality in the lightning network, the main issue being that some nodes might end up functioning like banks, processing the bulk of these transactions. Developer Kulpreet Singh set out to measure the centrality of nodes in the Lightning network.
