Bitcoin ($BTC) adoption is about to take another step forward with the Lightning Network today with a boost from payment processing startup CoinGate, which is adding all 4,000 of its merchants to the off-chain system. Those CoinGate merchants which will be able to accept payments via the Lightning Network include Swiss watch manufacturers Chronoswiss and Louis Chevrolet and more. The Lightning Network creates a layer on top of the bitcoin blockchain, where transactions can be passed back and forth before being added to the underlying blockchain. This should mean transaction speed is greatly increased while costs are significantly reduced.
