Segregated Witness and Lightning Network: Implications on the Future of Payment

Segregated Witness (SegWit) and Lightning Network are the key techniques that enable fast payment channel to be established between two (or more) users on the blockchain. This year, both Bitcoin and Litecoin have officially launched the Lightning Network on the mainnet, and users are able to perform near-instant transactions with minimal transaction fees, creating a vision of using cryptocurrency for micropayment. In this workshop, Dr. Wang Xinxi of the Litecoin Foundation will describe the blockchain scalability issues and the need for SegWit and Lightning Network. The workshop will cover principles of Lightning Network, how it was deployed on Litecoin, alongside with demo(s) by the instructor.

This workshop is suitable for anyone who aims to gain an in-depth understanding on performing payments on blockchain and its implications on businesses, and/or to develop own blockchain applications deploying Lightning Network.
