The Lightning network has been developed for Bitcoin as a means to solve its immediate scaling problem. It is likely that the technology developed by Lightning will also be implemented on other blockchains however there are very few other blockchains which suffer from the same high fees and slow transactions that Bitcoin does (this is thanks to Bitcoin’s overwhelming popularity). Ethereum is a close contender, with fees reaching a few dollars and transaction times slowing drastically during periods of prolonged use. In the case of Ethereum, other scaling solutions are being adopted as well as “Raiden”, which is built on similar technology to Bitcoin’s Lightning network and uses what are known as “state channels”. The smart contract based casino FunFair is using “Fate channels” to help scale the number of players that can bet on its platform.
