Solving problems associated with privacy, latency and scalability when it comes to executing transactions on the blockchain are primary topics of discussion and investigation.

While off-chain payment channels deal with with scaling, they can decrease privacy due to detectable transaction histories.

The ability to link payments of any given channel and the use of common intermediaries are key privacy concerns of the payment channel systems already proposed.

But how do we combine speed and privacy off the chain?

Achieving off-chain privacy

In this talk we hear from Ian Miers, who will be giving his answers to the questions surrounding off-chain privacy.

He will present Bolt — Blind Off-chain Lightweight Transactions, which provides techniques to preserve the privacy of payment channels for decentralized currency.

With constructions catering for unidirectional, bidirectional and indirect payment channels, Bolt ensures that transactions and parties involved remain untraceable.
