WHAT DOES DEIXIS DO?
Deixis provides digital contracts with provable properties, using blockchain technology without requiring new skills (from customers) except those any DBA might already have.
- Models a blockchain as a relational database
- Interoperates with an actual blockchain through its relational model
- Maps between relational databases of different schemas
- Allows multiple parties to share data on a common blockchain while accessing the shared data through the relational model of their individual database systems
- Legacy Compliant – Receives data from multiple legacy databases and consolidates diverse schemas in a mathematically rigorous way
- Consensus Driven – Projects data to a blockchain to determine consensus to a known degree of confidence
- Open to Outside Data – Receives consensus data from the databases themselvesand from outside sources
- Data Curation– Resolves data inconsistency by consensus confirmation of a maximal consistent subset of the data, rendering untrustworthy data sets trustworthy

About Deixis, PBC*
Mission: Develop technologies enabling digital governance of digital contracts.
Allen L Brown Jr, Patrick Santos, and Pamela Bell founded Deixis to transform governance of contracts from a social construct to a technical construct. Today, electronic evaluation of contracts is limited to determining whether the contract is internally consistent and consistent with other contracts. However, contracts are based on human trust. This means contracts should be consistent with the real world. Deixis introduces technology that can evaluate contracts against real world observations in near real time. In this way, a contract may be trusted because it has been shown electronically to reflect a state of affairs.
Many of the contexts in which we propose to do such governance involve the Internet of Things. An original scenario considered the enforcement of medical treatments and payment contracts. But there are explicit and implicit contracts in many scenarios, including the following:
- airport situational awareness regarding unauthorized motion in the airport’s air and ground space
- collective situational awareness for autonomous ground vehicles
- personal situational awareness and governance of the movement of one’s personal information through a social network
- movement of goods through a supply chain
- financial transfers among multiple parties
