The Teechain Payment Network.

Teechain is a new off-chain payment protocol that utilizes trusted execution environments (TEEs) to perform secure, efficient and scalable fund transfers on top of a blockchain.

Instant Transactions

Teechain offers instant and scalable payment transactions for existing blockchains. It supports point to point payment channels, and multi-hop payments in the network.

High Performance

Teechain achieves higher throughput and lower transaction latency than existing blockchains. Our experiments show that it is also 10x faster than off-chain competitors.

Practical Funding

Teechain enables practical funding of payment channels by allowing funds to be moved in and out of the network and between payment channels dynamically.

Offline Payments

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.

Secure Backups

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.

Research backed

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.
