Decentralized currency could change how construction firms move money, but construction-specific evidence remains at the prototype stage. A 2021 study built Ethereum prototypes for project bank-account payments, reverse-auction tendering, and tokenized project financing; it found the payment workflow simpler to implement than the other two. It did not establish sector-wide adoption, measured savings, or deployed transformation.
What “decentralized currency” means in construction
The phrase can blur together different kinds of digital money and the ledgers that record transactions. They are not interchangeable, and a blockchain workflow does not necessarily use a cryptocurrency.
- Cryptocurrency: a digital asset such as a public-chain cryptoasset, not a bank deposit or central-bank liability. Its price may fluctuate, and the arrangement raises questions about custody, conversion, and compliance.
- Stablecoin: a cryptoasset designed to track a reference value, often a currency. Its stability depends on the arrangement behind it; the label alone does not make it equivalent to insured bank money or central-bank money.
- Tokenized commercial-bank deposit: a digital representation of a claim on a commercial bank, subject to the issuing arrangement and applicable law.
- Tokenized central-bank money: a digital representation of central-bank money used in a particular payment or settlement design. It is not a public cryptocurrency.
Distributed-ledger technology (DLT) is the record-keeping and transaction infrastructure. A construction company might explore DLT to coordinate approvals or record payment status while settling in conventional money. The relevant question is therefore not simply whether to “use crypto,” but which payment instrument, ledger, participants, and rules a workflow would require.

Where construction workflows might change
A construction-specific study examined three possible applications: project bank accounts for payments, reverse-auction tendering, and asset tokenization for project financing. Its evidence came from three focus groups, a workshop, and working Ethereum prototypes, so these are exploratory models rather than proof of routine industry use. (Tezel et al., “Insights into Blockchain Implementation in Construction: Models for Supply Chain Management,” 2021)
#1 Best Overall
| Workflow | What a ledger could support | Evidence and practical implication |
|---|---|---|
| Project bank-account payments | Recording project-related payment instructions and transaction status among participants in a supply chain. | The study considered this model simpler to implement than tendering or project tokenization. It remains a prototype, not evidence of industry-wide deployment or measured savings. |
| Reverse-auction tendering | Recording bids and stages in a procurement process. | The study explored a blockchain-enabled bidding model. It would require workflow changes and integration with existing systems; evidence is exploratory. |
| Asset tokenization for project financing | Representing an asset or related rights as tokens in a financing model. | The study treated this as a more complex implementation. Tokenization alone does not provide regulatory approval, investor demand, or liquidity. |
For payments, a shared ledger might make recorded instructions or status visible to authorized participants. It cannot, by itself, verify that work was completed, resolve a disagreement over a change order, or ensure an invoice was approved correctly. Those decisions often depend on contract terms, inspections, identity checks, and off-ledger records. A ledger preserves recorded entries; it does not guarantee that the information entered was accurate.
What the evidence does—and does not—show
The construction study reported possible benefits such as streamlined, transparent transactions and trust-building, while identifying sector culture, integration with legacy IT, and regulatory compliance as challenges. Those are reported opportunities and implementation requirements, not measured industry-wide gains. The sources reviewed establish no representative construction adoption rate, quantified savings figure, or sector-wide outcome.
Official payment experiments illustrate what DLT can do in other settings, but they should not be read as construction trials:

- Project Samara: The Bank of Canada describes a limited real-world experiment involving one tokenized bond and wholesale central-bank money. Its paper says DLT-based issuance and settlement were technically feasible and could improve data integrity and reduce counterparty and settlement risk, but also discusses added complexity, governance and liquidity costs, operational risks, and legal and regulatory frictions. The authors characterize the findings as preliminary and illustrative; they concern financial-market infrastructure, not construction. (Bank of Canada, “Project Samara Research Paper,” March 2026)
- Project Agorá: The European Central Bank’s 2026 report describes a prototype using tokenized central-bank reserves and tokenized commercial-bank deposits for atomic settlement of cross-border wholesale transactions. It does not demonstrate construction use or establish a public cryptocurrency payment system. (European Central Bank, Project Agorá findings, May 27, 2026)
What a construction business should evaluate first
A project team considering a ledger-based workflow should define the operational problem before choosing an asset or platform. The key questions differ by use case:
- Workflow fit: Is the goal to coordinate project payments, run a procurement process, or finance an asset? A solution designed for one does not automatically fit the others.
- Money and settlement: What instrument will actually pay the contractor or supplier—bank money, a stablecoin, another cryptoasset, or tokenized bank or central-bank money? How will conversion, liquidity, settlement timing, and failed transactions be handled?
- Governance and access: Who can join, read, submit, approve, or correct records? Is a public, permissionless network appropriate, or is a permissioned arrangement needed? Who operates it and handles disputes?
- System integration: How will it connect with accounting, contract administration, project-management, procurement, and payment systems? The construction study specifically identified legacy IT integration as a challenge.
- Verification and exceptions: How will the system connect recorded payment events to approvals, delivery evidence, inspections, retention, change orders, and disputed invoices?
- Legal and compliance duties: Which parties handle identity checks, anti-money-laundering obligations, custody, tax reporting, contract enforceability, and insolvency risks? Answers depend on jurisdiction, instrument, and arrangement.
- Evidence maturity: Is the proposal a concept, prototype, pilot, or deployed system? What has actually been measured, in which setting, and against what baseline?
Regulatory and operational risks are instrument-specific
Rules vary by country and by the asset and service involved. In the United States, the Government Accountability Office’s 2023 report described federal oversight gaps for certain cryptoasset products and services, including stablecoins and trading platforms. That report is a U.S.-specific account, not a global regulatory summary or current legal advice. (U.S. Government Accountability Office, GAO-23-105346, June 22, 2023)
Before a real deployment, parties need to assess the applicable jurisdiction, payment instrument, custody arrangement, anti-money-laundering and know-your-customer duties, tax treatment, contract enforceability, and insolvency rules. They also need a way to handle incorrect inputs, access errors, disputed work, and operational outages. The ledger may preserve a record of what participants submitted, but it does not eliminate the underlying need for trusted approvals, clear governance, or dispute resolution.
Rank #4
Is blockchain likely to improve construction payments?
It could help coordinate and record a defined payment workflow when participants share clear rules and the system integrates with their existing processes. The construction-specific evidence gives the strongest early rationale to project bank-account payment arrangements, which were simpler to implement than the tendering and financing models studied. That is a comparative finding about prototypes, not proof that blockchain makes payments faster or cheaper in practice.
Construction businesses should treat cryptocurrency, stablecoins, tokenized deposits, and tokenized central-bank money as distinct options, not as synonyms for blockchain. The available evidence supports cautious experimentation and careful workflow design—not claims of sector-wide adoption or guaranteed savings.
