Gerdau | Oil, Gas and Chemicals | 30000 | $12.0B | Brazil | In-House Applications | Refrac Chain ( Developed by Cryptonomia), Blockchain Platform (Hathor) | Blockchain Platform | 2021 | n/a |
In 2021, Gerdau implemented Refrac Chain developed by Cryptonomia on the Hathor Blockchain Platform, a Blockchain Platform solution launched initially at a Gerdau site in Minas Gerais, Brazil. The deployment was a joint initiative with RHI Magnesita to digitize and secure contractual performance data for refractory supplies, moving transaction recording and measurements from manual spreadsheets into an auditable distributed ledger.
The Refrac Chain implementation consolidates technical, legal, and commercial workflows within a single application layer, and it includes automated financial calculation routines and programmatic measurement logic that replace prior manual calculations. The platform supports digital signatures and staged validation steps that are executed by designated representatives from both companies, and it provides a repository for proof artifacts including images, documents, text, video, and audio to increase auditability.
Operationally the deployment is a decentralized application operating on the Hathor Blockchain Platform and is scoped to supplier performance and contract management between Gerdau and RHI Magnesita at the Minas Gerais site, with an expressed intent to expand to additional Gerdau operations. The architecture records all transactional events on-chain and orchestrates off-chain processing through the application’s dedicated programmatic modules, enabling automated data transactions and traceability across the supplier relationship.
Governance was redesigned to introduce dual-party validation workflows, continuous on-chain audit trails, and monitored digital signature lifecycles, shifting control and verification from manual, spreadsheet-driven processes to instrumented blockchain workflows. The initiative explicitly aims to reduce repetitive work, increase transparency and security of contractual information, and accelerate operational decision making by providing a single, verifiable source of truth for refractory performance contracts.

RHI Magnesita | Manufacturing | 29207 | $4.1B | Austria | In-House Applications | Refrac Chain ( Developed by Cryptonomia), Blockchain Platform (Hathor) | Blockchain Platform | 2021 | n/a |
In 2021, RHI Magnesita went live with Refrac Chain, a Blockchain Platform developed by Cryptonomia that runs on the Hathor protocol, as a joint initiative with Gerdau. Refrac Chain was deployed initially at a Gerdau site in Minas Gerais, Brazil, operating as an exclusive pilot with the intention to extend the solution to additional operations over time. The implementation focused on machine-enforceable performance contracts between the two companies, recording transactions and contract events that had previously been tracked manually. RHI Magnesita implemented Refrac Chain to provide a single, auditable data source for refractory product performance and contract measurements.
Functional modules implemented in Refrac Chain include a dedicated financial calculation engine that automates contract measurement math, a contract performance measurement layer for service level and warranty monitoring, and a document and media evidence repository that stores images, documents, text, video, and audio as proof of events. The platform combines technical, legal, and commercial workflows in one interface, enabling automated data transactions and eliminating spreadsheet-based repetitive work. Refrac Chain, the Refrac Chain Blockchain Platform, applies validation steps and digital signature tracking to each stage of the contractual workflow.
Integrations and operational coverage were scoped around the bilateral supply relationship between RHI Magnesita and Gerdau, with Refrac Chain recording logistics, measurement, and contractual data at the Gerdau site and exposing that data to both trading partners for verification. The architecture emphasizes traceability and immutability on the Hathor Blockchain Platform, with on-chain records used for downstream financial calculations and auditability. Data custody and storage workflows were designed to support multi-format proof storage and to provide end-to-end visibility across the refractory supply and performance process.
Governance and process changes included role-based validation steps by representatives from both companies, monitored digital signatures throughout contract stages, and a unified workflow that replaced manual signoffs and spreadsheet reconciliation. The implementation establishes an auditable approval chain and a shared governance model between RHI Magnesita and Gerdau for contract validation and dispute prevention.
Explicit outcomes called out by the project sponsors include reduced repetitive administrative work, faster contract processing, improved transparency and security of contractual information, and more reliable shared insights to support decision-making. The project team positions Refrac Chain as a scalable industrial blockchain application with plans to expand beyond the initial site.
