Discreet Log Contracts

چکیده

Smart contracts [1] are an often touted feature of cryptographic currency systems such as Bitcoin, but they have yet to see widespread financial use. Two of the biggest hurdles to their implementation and adoption have been scalability of the smart contracts, and the difficulty in getting data external to the curency system into the smart contract. Privacy of the contract has been another issue to date. Discreet Log Contracts are a system which addresses the scalability and privacy concerns and seeks to minimize the trust required in the oracle which provides external data. The contracts are discreet in that external observers cannot detect the presence of the contract in the transaction log. They also hinge on knowledge of a discrete logarithm, which is a plus.

A trace-based model for multiparty contracts

In this article we present a model for multiparty contracts in which contract conformance is defined abstractly as a property on traces. A key feature of our model is blame assignment, which means that for a given contract, every breach is attributed to a set of parties. We show that blame assignment is compositional by defining contract conjunction and contract disjunction. Moreover, to specif...

Formal languages and analysis of contract-oriented software

In this work we present a visual model called CO Diagrams for the specification of e-contracts. This model includes specification of obligations, permissions, prohibitions, reparations and restrictions such as real time constraints. We also define a formal semantics of the visual model intended for the analysis and verification of the modeled contracts.

A dynamic deontic logic for complex contracts

We present a dynamic deontic logic for specifying and reasoning about complex contracts. The concepts that our contract logic CL captures are drawn from legal contracts, as we consider that these are more general and expressive than what is usually found in computer science (like in software contracts, web services specifications, or communication protocols). CL is intended to be used in specif...
