Tracing the moral code behind every token.
In the early morning of May 13, 2026, a brief report from a crypto-focused media outlet landed on my screen. It stated, with the cold neutrality of a terminal log, that Ukraine is using UK-made drones in its conflict with Russia. The report offered no model numbers, no payload details, no kill counts. Just four words: "Ukraine uses UK-made drones." But as someone who has spent years auditing smart contracts and tracing the ethical boundaries of decentralized systems, I saw something else in that sparse sentence. I saw a supply chain problem. I saw a verification gap. I saw a moral code waiting to be written into the blocks.
Building libraries where others build empires.
My journey into the intersection of blockchain and conflict began not in a war room, but in a Nairobi classroom. In 2020, during the DeFi Summer, I launched "The Open Ledger," a non-profit educational initiative. We translated complex DeFi mechanics into Swahili and English, publishing 12 whitepapers that reached 5,000 readers. But the most profound lesson I learned was not about liquidity pools or yield farming. It was about trust. When I mentored 20 young developers from underserved communities, I saw how the lack of verifiable records in supply chains—from grain to medicine—undermined their economic agency. Decentralization, I realized, is not just a technical feature; it is a foundational layer for accountability. And accountability is the first casualty of war.
The drone report from Crypto Briefing, though thin, is a microcosm of a much larger failure. The UK has confirmed supplying drones to Ukraine, including the "Hellhound" loitering munition and thousands of FPV attack drones under the "Drone Alley" project. These are not defensive tools; they are offensive weapons. Their deployment on the battlefield changes the nature of the conflict. But who verifies the provenance of these drones? Who ensures that the components—the GPS modules, the optical sensors, the explosive payloads—are authentic and have not been tampered with by adversaries? In the current system, the answer is a fragile chain of paper contracts, customs declarations, and bilateral trust. That chain is only as strong as its weakest human link.
Walking away from the hype to find the soul.
Here is where blockchain offers a path forward. Imagine a decentralized ledger that tracks every drone component from the factory floor in the UK to the launch site in Ukraine. Each part—the motor, the battery, the flight controller—is assigned a unique digital identity, recorded on an immutable blockchain. The manufacturer signs the initial record. The logistics provider updates the chain with shipping data. The Ukrainian military unit confirms receipt. The first time the drone is armed, a smart contract logs the timestamp and the operator’s digital identity. This is not science fiction. During my time as a senior smart contract auditor for the ZEIP-20 standardization working group in 2017, I saw how similar systems can be built for token transfers. The same principles apply to physical assets: immutability, transparency, and verifiability.
But the real challenge is not technical—it is philosophical. The military-industrial complex, like the crypto industry, is built on secrecy. The UK government does not want the world to know the exact number of Hellhound drones delivered, or their precise GPS coordinates. The Ukrainian military does not want to expose its operational patterns. And the drone manufacturers, like BAE Systems and Alpha Dynamics, guard their proprietary designs as state secrets. A blockchain-based supply chain threatens this opacity. It forces a trade-off between transparency and operational security. This is the same tension we face in decentralized finance: the desire for trustless verification versus the need for privacy.
Ethics is not a feature; it is the foundation.
From my experience auditing over 150 ERC-20 proposal drafts, I learned that technical neutrality often masks systemic bias. The same is true for military supply chains. The current system is biased toward those who hold the power to audit—governments, prime contractors, and intelligence agencies. A blockchain-based system could democratize verification, allowing independent journalists, international watchdogs, and even the Russian military to verify the origins of a drone. But would that be desirable? The answer depends on your ethical framework. From a values-driven perspective, transparency is an absolute good. It prevents the spread of counterfeit parts, reduces the risk of friendly fire, and holds suppliers accountable for quality. It also provides a historical record that can be used in post-conflict justice, tracing war crimes to specific actors.
Yet, there is a darker side. The same blockchain that prevents tampering could also enable real-time tracking by adversaries. If the Russian military can access the same ledger, they could predict the arrival of new drone shipments and target them. This is the classic blockchain oracle problem, applied to national security. In DeFi, we solve this by using multiple oracles and time delays. In warfare, the stakes are higher. A drone’s supply chain data must be timed and permissioned, accessible only to authorized parties after a certain delay. This requires a hybrid architecture: a public blockchain for the immutable record, combined with a private layer for access control. I have seen this approach work in the Zcash protocol, where selective transparency is achieved through zero-knowledge proofs. The same cryptographic primitives can be applied to military logistics.
Community over capital, always.
But let us not be naive. The adoption of blockchain in military supply chains faces formidable barriers. The first is inertia. The US and UK defense procurement systems are built on decades of legacy contracts and relational trust. Introducing a new technology requires a cultural shift, not just a technical upgrade. The second barrier is the fear of losing control. Governments are not willing to cede verification power to a decentralized network. They want to maintain the ability to modify records, suppress information, or even fork the chain if necessary. This is why the "code is law" mantra fails in the military context. In my analysis of DAO governance, I found that smart contract upgrade rights always sit with a few multi-sig admins. The same will be true for military blockchains: the multi-sig holders will be the heads of defense agencies, not anonymous developers. The promise of decentralization is compromised from the start.
Listening to the silence between the blocks.
Despite these challenges, the potential benefits are too significant to ignore. Consider the Hellhound loitering munition. It is a precision weapon that can wait for hours before striking a target. Its effectiveness depends on the integrity of its software and hardware. A single compromised component could turn a drone against its own forces. In 2022, I facilitated the launch of the "Savanna Voices" NFT collection, where we structured a DAO-governed royalty system. The same principle of on-chain governance can be applied to drone maintenance logs. Each time a drone is serviced, the technician signs a hash of the report. Each time a component is replaced, the new part’s digital identity is linked to the previous one. This creates an unbroken chain of custody that can be audited even after the drone is destroyed. The log is not just a record; it is a liability. If a drone malfunctions due to a faulty part, the manufacturer can be held accountable.
Preserving the human story in digital ledgers.
But the most profound impact of blockchain in warfare may be on the human level. During the 2022 bear market, I had to downsize my team and rewrite 40% of my course material to focus on risk management. That experience taught me that vulnerability is not weakness; it is the foundation of resilience. In the same way, a blockchain-based supply chain makes the military vulnerable to transparency, but that vulnerability can prevent the escalation of conflicts. If every drone strike can be traced back to the specific component that enabled it, soldiers and commanders become more cautious. They know their actions are recorded. This is the same logic that drives the push for on-chain identity in DeFi: accountability reduces fraud. In warfare, accountability reduces atrocities.
Now, let us turn to the contrarian angle. The assumption that blockchain can solve the trust problem in military supply chains is itself a form of hype. It ignores the fact that the physical world is not as clean as a digital ledger. A drone can be captured, its components removed, and the chain of custody broken. The blockchain can only record what is submitted; it cannot verify the physical integrity of a part. This is the same problem we face with NFT provenance: a certificate of authenticity does not prevent a forgery from being attached to the same token. To solve this, we need hardware-level attestation, such as tamper-proof chips that sign the component’s identity. These chips exist, but they are expensive and not yet integrated into every drone component. The cost of retrofitting the entire supply chain is prohibitive.
Furthermore, the enemy can also use blockchain. If Russia begins to record its own weapon supply chains on a private ledger, it could reverse-engineer the UK’s system or launch attacks on the blockchain itself. The blockchain is only as secure as its consensus mechanism. If the UK’s military blockchain uses a permissioned network with a small number of validators, it could be vulnerable to a 51% attack by a state actor. The Byzantine fault tolerance that protects Bitcoin is not easily replicated in a closed network. In my work with the ZEIP-20 group, I saw how centralized validators could introduce bias. The same risk applies here: the validators of the military blockchain could be compromised through espionage or coercion.
Another blind spot is the assumption that blockchain will reduce corruption. In reality, it could make corruption more sophisticated. If a manufacturer wants to sell defective parts, they can create a fake digital identity for a counterfeit component and record it on the blockchain. The ledger will show an authentic history, but the part is still a fake. This is the immortal data problem: once false information is recorded, it is permanent. The military would need a parallel system of physical inspections to verify the on-chain data, which defeats the purpose of automation. I encountered this exact issue during the DeFi Library Project, where we had to manually verify the identities of the developers we mentored. The blockchain cannot replace human judgment; it can only augment it.
Despite these limitations, the strategic value of a blockchain-based supply chain is undeniable. It provides a tamper-evident, time-stamped record that can be used in diplomatic negotiations. If Ukraine strikes a target with a UK-made drone, and Russia claims it was a civilian area, the blockchain can provide evidence of the drone’s flight path and payload. This is not just a technical tool; it is a narrative weapon. In the information war, who controls the data controls the story. The UK has already shown a willingness to use narrative warfare, as seen in the public confirmation of drone deliveries. A blockchain-based supply chain would amplify that narrative by providing a cryptographic proof of action.
Ethics is not a feature; it is the foundation.
Looking forward, I believe the convergence of blockchain, AI, and drones will define the next decade of conflict. The AI-Blockchain Ethics Charter that I co-authored in 2026, adopted by two East African regulatory bodies, proposes mandatory transparency audits for AI-driven smart contracts. The same principles should apply to autonomous weapons. A drone that uses AI to identify targets must have its decision-making logic recorded on an immutable ledger. This is not just about accountability; it is about preventing algorithmic bias from causing civilian casualties. The charter we drafted requires that any AI-driven weapon system must maintain a log of its training data, model version, and decision outcomes. This log should be auditable by independent third parties, subject to national security constraints.
But the path to this future is not smooth. The military-industrial complex will resist any loss of control. The private sector, eager for contracts, will compromise on transparency. The crypto industry, obsessed with hype, will oversell the technology. As someone who has survived the winter, I know that the real value lies not in the promises, but in the slow, patient work of building libraries where others build empires. The blockchain for military supply chains will not be built by startups with ICOs; it will be built by small teams of dedicated engineers, working with the military, to integrate cryptographic verification into existing systems. It will be a gradual process, marked by failures and setbacks.
Tracing the moral code behind every token.
In the end, the question is not whether blockchain can be used in warfare. It will be. The question is whether we, as a community of developers, ethicists, and educators, will guide that use toward accountability and justice. The silent code of war is waiting to be written. Let us ensure it is written with integrity.
Walking away from the hype to find the soul.
I recall the moment in 2021 when I helped launch the "Savanna Voices" NFT collection. The initial hype was immense—1,200 items sold in 48 hours, raising $150,000 for the artists. But when the frenzy subsided, the community engagement dropped. The artists felt exploited. I learned that hype without ethics is a hollow shell. The same lesson applies to the military blockchain. If we deploy the technology without a robust ethical framework, we risk creating a new layer of opacity, not transparency. The blockchain will become a tool for justification, not accountability.
As I write this, I am sitting in my Nairobi office, looking at the small team of four that survived the 2022 winter. We are planning a new course on blockchain for supply chain integrity, with a focus on conflict zones. The course will be open-source, free to all, and translated into multiple languages. It will teach not just the technical implementation, but the ethical considerations. Because at the end of the day, the most important smart contract is the one we make with ourselves: to use technology in service of human dignity, not in pursuit of power.
Building libraries where others build empires.
The drone that flew over Ukraine this morning carried a payload of explosives. It also carried a payload of meaning. The question is whether that meaning will be shaped by the silent code of war, or by the transparent code of a blockchain. I choose the latter, and I invite you to join me.
