Abstract This paper provides an analysis of how concepts pertinent to legal contracts can influence certain aspects of their digital implementation through smart contracts, as inspired by recent developments in distributed ledger technology. We discuss how properties of imperative and declarative languages including the underlying architectures to support contract management and lifecycle apply to various aspects of legal contracts. We then address these properties in the context of several… 
Symboleo: Towards a Specification Language for Legal Contracts
TLDR
This paper proposes a formal specification language for contracts, called Symboleo, where contracts consist of collections of obligations and powers that define the legal contract’s compliant executions, to enable formally verifying contracts to detect requirements-level issues and to generate executable smart contracts (e.g., on blockchain technology).
Hercule: Representing and Reasoning About Norms as a Foundation for Declarative Contracts Over Blockchain
TLDR
Hercule operationalizes declarative contracts over semistructured databases, the underlying representation for practical blockchain such as Hyperledger Fabric and Ethereum, and exploits the map-reduce capabilities of such stores to compute norm states.
A Survey of Smart Contract Formal Specification and Verification
TLDR
This survey investigates formal models and specifications of smart contracts presented in the literature and presents a systematic overview in order to understand the common trends and identify gaps.
A Legal Interpretation of Choreography Models
TLDR
An approach at connecting existing models to Legal Ontologies (LOs) on the example of choreography models is explored, effectively interpreting them as legal contracts.
Smart Contract and Blockchain Based Contract Management System
TLDR
This paper presents theoretical and practical research on the possibilities of applying smart contracts in the field of law and a contract management system which allows users to conclude contracts based on blockchain technology and an example of a smart allotment contract written using the Solidity programming language.
A Unifying Model of Legal Smart Contracts
TLDR
A unifying model is given that encapsulates essential components of legal smart contracts in a model-driven architecture and may serve as a basis for comparing existing modeling frameworks, which is demonstrated by applying it to a set of eight distinct languages.
Smart Contracts: From Formal Specification to Blockchain Code
TLDR
This thesis contributes a syntax and axiomatic semantics for Symboleo, with concepts rooted in a legal ontology, and supported by an editor, and provides an analysis of possible target smart contract programming languages.
Legally Enforceable Smart-Contract Languages
TLDR
This study reviews existing Smart Contract Languages (SCL) and identifies properties that are critical to any future SCL for drafting legally binding contracts and finds 10 SCL properties that enable legally compliant DAOs.
Legal smart contracts in Ethereum Block chain: Linking the dots
TLDR
This paper addresses the problem of contract update by introducing a new versioning system that keeps track of the changes and links the different versions using a linked list, and proposes a system architecture where the user interface, the application logic and the blockchain are smoothly integrated in a manner that each part of the system contributes for producing a flexible and transparent execution.
Regulating Blockchain Smart Contracts with Agent-Based Markets
TLDR
This paper presents an overview of the agreement pipeline, considering regulation-enabled systems and compares the implementation of auction agreements purely on the blockchain with a hybrid approach where markets are active agents that can ensure regulation outside the contractual phase and contract execution runs on blockchain.

Evaluation of Logic-Based Smart Contracts for Blockchain Systems
TLDR
A fundamental challenge is emphasized - algorithms for logic approaches have to be efficient, but they also need to be literally cheap as measured within the environment where they are deployed and according to its economic rules.
Smart Contract Templates: essential requirements and design options
TLDR
The design landscape of potential formats for storage and transmission of smart legal agreements is explored, and essential requirements are identified and a number of key design options are described, from which future development of standardised formats for defining and manipulatingsmart legal agreements are envisaged.
Smart Contract Templates: foundations, design landscape and research directions
TLDR
A simple semantic framework for smart contracts is explored, covering both operational and non-operational aspects, and templates and agreements for legally-enforceable smart contracts are described, based on legal documents.
Validation and Verification of Smart Contracts: A Research Agenda
TLDR
The issues and research challenges involved in the validation and verification of smart contracts, particularly those running over blockchains and distributed ledgers, are explored.
A Formal Analysis of a Business Contract Language
TLDR
The paper shows how this formalism for the representation of contrary-to-duty obligations can be mapped onto the key policy concepts of a contract specification language, called Business Contract Language (BCL), previously developed to express contract conditions for run time contract monitoring.
A declarative approach to business rules in contracts: courteous logic programs in XML
TLDR
This work gives a new fundamental knowledge representation formalism: a generalized version of Courteous Logic Programs (CLP), which expressively extends declarative ordinary logic programs (OLP) to include prioritized conflict handling, thus enabling modularity in specifying and revising rule-sets.
Representing business contracts in RuleML
TLDR
This paper presents an approach for the specification and implementation of translating contracts from a human-oriented form into an executable representation for monitoring in the setting of RuleML, and how to extend it to cover deontic and defeasible aspects of legal language.
Inter-enterprise contract architecture for open distributed systems: security requirements
TLDR
The concept of binding is used to describe the interactions between the components of the contract architecture so that standard contract sequences can be stored in a public repository for future reuse.
Towards formal modeling of e-contracts
  • O. MarjanovicZ. Milosevic
  • Computer Science
    Proceedings Fifth IEEE International Enterprise Distributed Object Computing Conference
  • 2001
TLDR
The paper presents the initial ideas for formal modeling of e-contracts, including specification of deontic constraints and verification ofDeontic consistency associated with roles in a contract, precise modeling of temporal constraints/estimates and verify of temporal consistency of an e- contract, and finally scheduling of the required actions.
Automatic Conflict Detection on Contracts
TLDR
This paper presents a trace semantics of $\mathcal{CL}$ suitable for conflict analysis, and a decision procedure for detecting conflicts, and discusses its implementation and looks into the applications of the contract analysis approach.
