Teechain offers instant and scalable payment transactions for existing blockchains. It supports point to point payment channels, and multi-hop payments in the network.
Teechain achieves higher throughput and lower transaction latency than existing blockchains. Our experiments show that it is also 10x faster than off-chain competitors.
Teechain enables practical funding of payment channels by allowing funds to be moved in and out of the network and between payment channels dynamically.
Teechain can operate securely and efficiently without access to the underlying blockchain. By utilizing secure trusted hardware, Teechain offers offline payments without compromising on security.
Teechain provides fault tolerance to overcome hardware failures and compromises. It offers both committee chains and the use of persistent storage to protect funds from ever being lost.
Teechain is a research project between Imperial College London, and the Initiative for Cryptocurrencies and Contracts at Cornell University. Our work has already been published at SOSP'19 and BITCOIN'17. Further advancements are under way.
