EstonianGovernment | Government | 180 | $20M | Estonia | Guardtime | Guardtime KSI Blockchain | Blockchain Platform | 2018 | n/a |
In 2018 EstonianGovernment deployed Guardtime KSI Blockchain, a Blockchain Platform, across its government networks to establish tamper-evident provenance for electronic records. With Guardtime KSI Blockchain in place, history cannot be rewritten and the authenticity of electronic data can be mathematically proven, ensuring that no one including hackers, system administrators, or government actors can manipulate recorded data undetected.
The implementation configured Guardtime KSI Blockchain as a cryptographic timestamping and signature verification service embedded at the network layer, delivering immutable audit trails and verifiable evidence of integrity for digital documents and records. Functional capabilities emphasized in the rollout include cryptographic timestamping, signature-based verification, and persistent ledger anchoring to produce non‑repudiable proof of data creation and modification times.
Operational coverage focused on Estonian government networks and electronic services, providing a common integrity service for records used across public sector workflows. Governance practices centered on externally verifiable proofs rather than access control alone, enabling independent verification of record authenticity without exposing underlying data.
The deployment of Guardtime KSI Blockchain, a Blockchain Platform, produced system-level auditability and verifiability of electronic records, aligning technical controls with public sector accountability requirements. This architecture reduces the risk of undetected data tampering by creating mathematically provable evidence of any alteration to stored records.

Lockheed Martin | Aerospace and Defense | 121000 | $71.0B | United States | Guardtime | Guardtime KSI Blockchain | Blockchain Platform | 2020 | n/a |
In 2020, Lockheed Martin integrated Guardtime KSI Blockchain, deploying Guardtime KSI Blockchain as a Blockchain Platform across Lockheed Martin Aeronautics to introduce immutable digital integrity across its software supply chain. The initiative embeds cryptographic integrity into architectures supporting research, design, development, manufacturing, integration and sustainment of advanced products and services.
The implementation leverages KSI cryptographic signatures to provide a mathematically verifiable end to end integrity check, extending from external software suppliers through internal development pipelines to verification on delivered military systems. Functional capabilities implemented include cryptographic timestamping and signature anchoring, integrity attestation of build artifacts, and verification gates integrated into development and certification workflows.
Guardtime KSI Blockchain was integrated into development toolchains and into the architecture of digitally directed manufacturing equipment to deter and detect unauthorized residuals from third party maintenance actions, covering both software engineering and production operations within Aeronautics. Operational coverage explicitly spans external software suppliers, internal development teams, manufacturing sites and delivered platforms, with integrity verification steps designed for fielded military systems.
Governance and process changes aligned the deployment with continuous Agile development practices to ensure integrity checks are embedded in CI/CD and verification processes, and to support aircraft certification workflows. The collaboration instituted provable data integrity processes that change the control flow of digital data and processes into auditable cryptographic attestations across the supply chain.
The stated outcome is mitigation of cyber threats across the software supply chain and assurance of high levels of digital security, aiming to enhance the integrity of aircraft and enable mission success in contested cyber environments. Guardtime KSI Blockchain provides a mathematically provable process for data integrity from supplier code through delivered platforms.

Verizon | Communications | 99400 | $134.8B | United States | Guardtime | Guardtime KSI Blockchain | Blockchain Platform | 2018 | n/a |
In 2018 Verizon implemented Guardtime KSI Blockchain as a Blockchain Platform within Verizon Enterprise security services. The deployment positioned Guardtime KSI Blockchain to provide cryptographic attestation and timestamping capabilities to strengthen data integrity controls across Verizon operations.
Implementation centered on KSI keyless signature infrastructure capabilities, delivering immutable audit trails, data timestamping, and integrity verification for both physical and digital supply chains. Verizon emphasized privacy, portability and scalability when configuring Guardtime KSI Blockchain, and planned to layer proven managed security services on top of the platform to operationalize monitoring, incident response, and customer-facing security offerings.
Operational coverage was focused on Verizon Enterprise Solutions and related security operations teams, with KSI-based integrity checks embedded into security workflows and managed services delivery models. Governance and process changes targeted the inclusion of cryptographic attestation in change control and supply chain validation, an approach intended to help maintain the integrity of critical infrastructure, protect physical and digital supply chains, and safeguard customers information systems.
