Blockchain protocols are inherently limited in transaction throughput and latency. Recent efforts to address this problem have focused on off-chain payment channels. While such channels can improve transaction speeds, deploying them securely on top of the Bitcoin blockchain has been difficult.

How do we maintain low latency and high throughput when secure implementation requires changes to the underlying protocol and ecosystem?

Improving (off-chain) payment protocol

Teechain is a payment network that enables secure and scalable transfers thanks to its use of multiple trusted execution environments (TEEs). It is the first network that assumes asynchronous access to the blockchain, instantly establishing payment channels.

Compared to existing solutions, Teechain’s capabilities are vastly greater. While current methods process 1,000 transactions per second, Teechain manages over 30,000, with just a 0.3-second latency.

We hear from Joshua Lind, the primary developer of the Teechain Payment Network, who will take us through this off-chain payment method; explaining the successful results and the working behind them.
