Elon Musk: Lightning Can Solve Bitcoin’s Scaling Problem
For the Tesla and SpaceX CEO, Bitcoin is too slow, expensive and power-hungry to thrive. He thinks a five-year-old Bitcoin payments protocol is the way forward.
Tesla and SpaceX CEO Elon Musk, Bitcoin's former posterboy and now its number-one persona non grata, said that the Bitcoin network could meet rising demand if its users adopted the Lightning Network, a payments network that makes Bitcoin transactions quicker and cheaper.
“Bitcoin hashing (aka mining) energy usage is starting to exceed that of medium-sized countries. Almost impossible for small hashers to succeed without those massive economies of scale,” he tweeted today. “For now, Lightning is needed.”
Achieving truly decentralized finance – power to the people – is a noble & important goal.
Layer count depends on projected bandwidth & compute, both rising rapidly, which means single layer network can carry all human transactions in future imo.
Lightning is a piece of software that processes Bitcoin transactions outside of the Bitcoin blockchain to lighten the load on the network.
Without Lightning, it currently costs an average of $13 in fees and takes 14 minutes to move funds across the Bitcoin network.
With Lightning, moving funds costs around one satoshi, the smallest unit of a bitcoin (equivalent to 100 millionth of a bitcoin), and transactions are near-instantaneous.
Silicon Valley-based Lightning Labs started building Lightning in 2016. The company counts Twitter and Square CEO Jack Dorsey among investors. A protocol launched in beta in 2018.

Critics argue that Lightning sacrifices decentralization, since some of the computational work takes place away from the main Bitcoin blockchain.
“Achieving truly decentralized finance – power to the people – is a noble & important goal,” said Musk, in response to BTCSession, a crypto YouTuber who had asked whether Musk had considered whether Lightning sacrificed on decentralization.
