Open and decentralized blockchains, are blockchains where any participant can join and leave the network at any time. Unfortunately, permissionless blockchains feature a very low transaction throughput of about 10 to 100 transactions per second and each transaction typically requires minutes to confirm.
Besides sharding designs, different off-chain payment designs have been proposed as a solution to scaling both costs and speed. An off-chain transaction is one that is not carried out over the blockchain, but over an out-of-band Internet connection, while the transaction is still secured by the blockchain. In this talk, we highlight the different off-chain payment designs, and discuss the benefits and drawbacks of each design. To this extend, we will for example discuss Lightning, Raiden, TumbleBit and the Liquidity.Network.
