Private and Trustworthy Distributed Lending Model Using Hyperledger Besu

Distance and Private Information in Lending

We study the effects of physical distance on the acquisition and use of private information in informationally opaque credit markets. Using a unique data set of all loan applications by small firms to a large bank, we show that borrower proximity facilitates the collection of soft information, leading to a trade-off in the availability and pricing of credit, which is more readily accessible to ...

Is Distributed Trust More Trustworthy?

Hyperledger Fabric: A Distributed Operating System for Permissioned Blockchains

Fabric is amodular and extensible open-source system for deploying and operating permissioned blockchains and one of theHyperledger projects hosted by the Linux Foundation (www.hyperledger.org). Fabric is the first truly extensible blockchain system for running distributed applications. It supports modular consensus protocols, which allows the system to be tailored to particular use cases and t...

Vis-à-vis Cryptography: Private and Trustworthy In-Person Certifications

The growing role of mobile devices in previously face to face interactions presents new domains for cryptographic applications. At the same, time the increased role of digital systems raises new security and privacy issues. With some thirty thousand notifications sent, inSPOT.org’s electronic notification of exposure to sexually transmitted infections is one such concerning development. This pa...

Making Distributed Computation Trustworthy by Construction

Trustworthy computing systems must provide data confidentiality and data integrity, and must be available. This paper shows that these security properties can be provided by construction, by compiling high-level, security-typed source code into explicitly distributed, security-typed target code. This code transformation provably preserves the confidentiality, integrity, and availability propert...
