PISA Research
Our mission is to build and protect global, privacy-preserving, permissionless and off-chain smart contracts.

Off-chain SoK (2019)
A systemization of knowledge for off-chain protocols. It explores channels, routing, commit chains, privacy and security.
PISA (2018)
We proposed the first accountable third party watching service (PISA) that can be deployed on Ethereum without any hard-fork.
Case Study (2018)
We have performed and published the first empirical case study to evaluate state channels as a scaling solution for cryptocurrencies.
Sprites Channel (2017)
We are among the first team to propose how to concretely construct (and peer-reviewed) off-chain state channels with Sprites and Kitsune.
E-Cash Survey (2016)
Summarises the field of micropayment protocols including classical e-cash protocols, real-world products and cryptocurrencies.
Channel Survey (2016)
First survey to explore the concept of channel-based networks based on chat room conversations, mailing lists, private conversations, etc.
Watch & Protect
Our focus is building an accountable watching service, PISA, to support off-chain protocols in Bitcoin and Ethereum.
Off-chain Protocols
Scales the network by simply reducing its load. Transact locally instead of the global network, while retaining similar security guarantees.
Third-Party Watchers
Off-chain protocols assume users are always online. We will alleviate this assumption by watching off-chain protocols on behalf of users.
The team behind PISA is world-class; at Counterfactual we’re excited to be working with them to make take state channels to production
The PISA team has long-standing experience in the field of state channels and we at Raiden Network appreciate their excellent work. We are looking forward to continuing the collaboration in the future.
