Abstract
from arXiv · showhide
Blockchain technology has recently gained widespread attention by media, businesses, public sector agencies, and various international organizations, and it is being regarded as potentially even more disruptive than the Internet. Despite significant interest, there is a dearth of academic literature that describes key components of blockchains and discusses potential applications. This paper aims to address this gap. This paper presents an overview of blockchain technology, identifies the blockchain's key functional characteristics, builds a formal definition, and offers a discussion and classification of current and emerging blockchain applications.
1. INTRODUCTION
Despite widespread interest in blockchain, academic discussion of its underlying functions and potential business applications is limited. The paper bridges that gap with a technological primer, a formal definition, and a classification of emerging applications.
1. INTRODUCTION
- Blockchain is presented as a way to exchange asset transactions transparently among disparate agents without a controlling central authority.The paper attributes this trust to cryptographic operation.Source: §1 · p. 1
- The paper identifies a gap in academic literature on blockchain’s underlying technology and potential business applications.Source: §1 · p. 1
- The paper aims to identify blockchain’s key characteristics, build a formal definition, and classify emerging applications.Source: §1 · p. 1
2. CONCEPTUAL FOUNDATIONS
The paper traces blockchain’s foundations and describes its transaction, trust, and governance mechanisms. It formalizes core characteristics and distinguishes public, private, and hybrid forms.
2.1 Origins & Underpinnings
- Blockchain combines software engineering, distributed computing, cryptography, and economic game theory; Bitcoin’s chain links hashed records and uses proof-of-work to coordinate additions.The paper describes records as transaction pools linked to parent blocks, with network copies coordinated through proof-of-work.Source: §2.1 · pp. 1–3
2.2 Functional Characteristics
- Blockchain can be applied where assets are managed and transactions occur, supporting custody through trust, consensus, security, and smart contracts.Source: §2.2 · p. 3
2.2.1 Transactions & Smart Contracts
- Transactions exchange assets under service rules, while smart contracts embed coded logic in the blockchain to govern transactions autonomously.The paper notes that such rules can support advanced transactions, including escrow and multi-party signatures.Source: §2.2.1 · p. 3
2.2.2 Consensus & Trust
- Consensus validates added blocks across decentralized copies, replacing a central authority with community verification and computationally costly cryptographic mechanisms.The paper describes proof-of-work and other consensus models, including proof-of-stake, proof-of-burn, proof-of-elapsed-time, and proof-of-capacity.Source: §2.2.2 · p. 4
2.2.3 Public and Private Blockchains
- Public chains are open to participation, private chains restrict reading and writing by privilege, and hybrid chains limit access to a privileged group.Source: §2.2.3 · p. 5
- The paper formalizes four core characteristics: immutability, decentralization, consensus-driven verification, and transparency.It links these characteristics to permanent transaction records, networked copies, validation without a central authority, and auditable transaction histories.Source: §2.2.3 · p. 5
3. TOWARDS A DEFINITION
Earlier definitions variously restrict blockchain to cryptocurrency ledgers or emphasize distribution without fully capturing decentralization. The paper offers a concise definition and connects its core elements to transparency and digital-asset applications.
3. TOWARDS A DEFINITION
- Coinbase (2017) and Oxford Dictionaries (2018) frame blockchain around cryptocurrency transactions, while Webopedia (Stroud, 2015) broadens the definition to distributed tracking and transfer of assets.The paper argues that ledger use is a feature of some blockchain applications, not the technology’s essence.Source: §3 · p. 5
- A blockchain differs from a merely distributed system because every participant maintains a full node and independently enforces rules using local information.The paper says this decentralization means the network can continue with only one operational node.Source: §3 · p. 6
- The paper defines blockchain as a decentralized database of sequential, cryptographically linked blocks of digitally signed asset transactions governed by consensus.Source: §3 · p. 6
- The definition highlights a peer-to-peer database governed by rules, shifting trust away from traditional agents and supporting digital-asset sharing, tracking, and auditing across industries.Source: §3 · p. 6
4. BLOCKCHAIN BUSINESS APPLICATIONS
The paper organizes blockchain business applications by their value propositions and four roles: development platform, smart-contract utility, marketplace, and trusted-service application. It describes use cases and proposes classifying industry offerings by blockchain access and scope.
4.1 Value Proposition of Blockchain Technology
- Blockchain’s ATOMIC value elements—assets, trust, ownership, money, identity, and contracts—support programmable asset creation, management, and transfer without intermediaries.The paper associates disintermediation with cheaper transaction fees and faster execution.Source: §4.1 · p. 6
4.2 Blockchain as a Development Platform
- Blockchain-as-a-Service platforms offer developers inexpensive test-blockchain environments for rapid prototyping, despite specialized skill requirements and immature toolkits.The paper also describes services for secure industrial data sharing and transaction verification.Source: §4.2 · p. 6
4.3 Blockchain as a Smart Contract Utility
- Smart contracts execute code-stored utility when predetermined conditions occur, supporting functions such as escrow, multi-party transactions, notarization, and time stamping.They can shift activities often managed by central authorities to the blockchain.Source: §4.3 · p. 7
4.4 Blockchain as a Marketplace
- Blockchain marketplaces combine cryptocurrency payment infrastructure and digital-asset ownership tracking to support peer-to-peer trade without a governing authority.The paper also describes potential workforce marketplaces where providers transact flexibly and transparently.Source: §4.4 · p. 7
4.5 Trusted-Service Application
- Trusted-service applications combine programmable assets, trust, ownership, money, identity, and contracts to provide secure, disintermediated services to end users.The paper notes that many such applications use public blockchains and APIs.Source: §4.5 · p. 7
- The proposed matrix classifies industry offerings by access (application or service) and scope (public, private, or hybrid), with healthcare records as private services and land registration as open applications.Figure 4 presents the access-versus-scope matrix.Source: §4.5 · pp. 7–8, Figure 4 · p. 8
5. CONCLUSION
The paper presents a conceptual overview of blockchain functions and potential business applications. It defines core characteristics and discusses examples of where they may be useful.
