This document provides an overview of smart contracts in BC/DLT systems; describing what smart contracts are and how they work. It also discusses methods of interaction between multiple smart contracts. This document focuses on technical aspects of smart contracts. Smart contracts for legally binding use and applications will only be briefly mentioned in this document.

Overview

ISO/TR 23455:2019 provides a technical overview of smart contracts in blockchain and distributed ledger technology (BC/DLT) systems. It explains what smart contracts are, how they operate within DLT platforms, and how multiple smart contracts interact. The report focuses on technical aspects (architecture, execution, lifecycle and interoperability); legal enforceability is only briefly discussed. This Technical Report was prepared by ISO/TC 307 and is intended as guidance rather than a prescriptive standard.

Key technical topics and considerations

Definitions and history: clear working definitions of smart contracts, ledger, token, transaction, on‑chain vs off‑chain, and DLT oracles; background from Szabo to modern BC/DLT implementations.

Operation of smart contracts: the concept of a smart contract as a computer program stored on a distributed ledger and how execution outcomes are recorded.

On‑chain vs off‑chain: deployment and execution differences, trade‑offs for determinism, performance and trust.

Access to real‑world information (DLT oracles): patterns for bringing external data on‑chain, event delivery, and transferring control between smart contracts and external processes.

Life cycle management: creation, operation, modification, termination, migration, update and rollback mechanisms supported by ledgers.

Security: technical security considerations specific to smart contract code, execution environments and ledger interactions.

Inter‑contract interaction and interoperability: methods for interaction between multiple smart contracts, cross‑chain and sidechain transaction implementations, and importance of semantics, syntax, inputs and language choices for interoperability.

Informative annexes: examples of implementations, domain‑specific languages (DSLs), and a catalogue of applications and use cases.

Practical applications and who uses this report

ISO/TR 23455:2019 is useful for:

Blockchain developers and architects designing smart contract systems and integration patterns.

Platform vendors and system integrators evaluating on‑chain/off‑chain trade‑offs, oracles and cross‑chain strategies.

Solution designers in finance, supply chain, identity and IoT seeking technical guidance on lifecycle, security and interoperability of smart contracts.

Standards bodies, regulators and technical managers who need a neutral, technical reference on smart contract mechanics (not legal advice).

Related standards and references

Prepared by ISO/TC 307 (Blockchain and distributed ledger technologies).

Cross‑references within the report include other ISO/IEC and ISO technical reports cited for terminology and related concepts (examples in the text include ISO/IEC 14776‑323:2017 and ISO/TS 19299:2015).

ISO/TR 23455:2019 is a technical reference to help practitioners understand smart contract mechanisms, security considerations, and interoperability challenges in modern BC/DLT systems.
