Announcement
Traditional data and operations management across organizations and on the web can involve inefficient transaction reconciliation between siloed databases, password fatigue, and single points of failure. This often results in concerns over interoperability, security, and privacy of data that affect both users and businesses.
Blockchain technology has enabled a new software paradigm for managing digital ownership in partial or zero-trust environments. It uses tokens to conduct transactions, exchange verifiable data, and achieve coordination across organizations and on the web. Data models with varied capabilities and scopes have been defined to issue tokens. By allowing for the design of programmable digital assets that can represent different forms of ownership, these models enable users to store, move, and even create value on top of shared or public digital infrastructures.
NIST announces the release of Draft NISTIR 8301, Blockchain Networks: Token Design and Management Overview, which provides a high-level technical overview and conceptual framework of token designs and management methods. The document highlights the different types of tokens and how they are held in custody. It then examines transaction management under three fundamental aspects: validation, submission, and viewability. Infrastructure tools used to develop applications that integrate blockchain networks and second layer protocols are also reviewed. Finally, the paper presents deployment scenarios and use cases for tokens before concluding with potential breakthroughs in privacy-preserving verifiable data exchange. The terminology, concepts, properties, and architectures introduced in this work can facilitate understanding and communications among business owners, software developers, cybersecurity professionals within an organization, and individuals who are or will be using such systems.

Blockchain technology has enabled a new software paradigm for managing digital ownership in partial- or zero-trust environments. It uses tokens to conduct transactions, exchange verifiable data, and achieve coordination across organizations and on the web. Fundamental to this representation is that users have the ability to directly control token custody in digital wallets through public-key cryptography and to interact with one another in a peer-to-peer manner. Blockchain networks provide secure transaction reconciliation, linkage, and storage in a master record-keeping distributed ledger—forming mutually operated virtual machines. Data models with varied capabilities and scopes have been defined to issue tokens, which additional protocols can help manage while allowing for separation of concerns. Security and recovery mechanisms make it possible for users to set up self-hosted, externally hosted, and hybrid account custody models. Token transfer and collateralization can underpin more advanced operations, such as non-custodial exchanges. Scaling schemes have been developed to accommodate transactions off-chain with deferred on-chain settlement, as well as transaction submission rules to fit in with different deployment scenarios and privacy-enhancing techniques to protect user confidentiality. Software design patterns and infrastructure tools make it easier to integrate blockchain networks, wallets, and external resources in user interfaces. This document provides a high-level technical overview and conceptual framework of token designs and management methods. It is built around five views: the token view, wallet view, transaction view, user interface view, and protocol view. The purpose is to lower the barrier to study, prototype, and integrate token standards and protocols by helping readers understand the building blocks involved both on-chain and off-chain.
