About Pisa:

As deployed today, cryptocurrencies do not scale. To tackle this scaling problem, Patrick and co. introduce Pisa, which complements existing work on so-called "layer 2" solutions.

Pisa focuses generic state channels which can be used to build any application (i.e. payments, auctions, boardroom voting, gaming). The core contribution is a new protocol for hiring a new third party agent called the custodian. This custodian is designed to help alleviate a new assumption in state channels which require every participating party to remain online (synchronied with the blockchain).

In this video, Patrick explains why a generic state channel is desirable, then outlines his proposed solution in Pisa. The primary innovation is the introduction of a custodian that can be held accountable by a customer in the event the custodian fails to watch the channel on their behalf... a much needed solution for on-chain scalability!
