On May 21, 2024, an Iranian commercial airliner touched down at Sana'a International Airport. At the same time, Saudi Arabian fighter jets vacated their forward operating bases in Yemen. Two seemingly unconnected events, yet their collision point is a perfect storm of gray-zone geopolitics—and a stark reminder of why we need verifiable, decentralized infrastructure to prevent the next escalation.
Context The Bab el-Mandeb strait is one of the world’s most vital chokepoints, through which roughly 10% of global oil and LNG passes. For years, Yemen has been the stage for a proxy war between Iran and Saudi Arabia. The Houthi rebels, backed by Tehran, have been pitted against the Saudi-led coalition. The use of a civilian aircraft to deliver goods—humanitarian or military—is a classic gray-zone tactic. It forces the opponent into a dilemma: shoot down a civilian plane and invite international condemnation, or let it through and permit Iranian influence to deepen. Saudi Arabia’s withdrawal of fighter jets, meanwhile, signals either exhaustion or a strategic recalibration.
But here’s the blockchain angle: in a world where every cargo manifest, every flight path, and every fuel load could be recorded on an immutable, public ledger, the ambiguity that enables gray-zone tactics would evaporate. The core problem is not a lack of data—it’s a lack of trust in the data. Current systems rely on centralized authorities (airlines, intelligence agencies, governments) to interpret intentions. Blockchain offers a way to make the data self-authenticating.
Core Insight Let’s trace this back to a principle I stumbled upon in 2017. I was a 19-year-old economics undergraduate in Tokyo, obsessed with ICOs. Instead of speculating, I audited smart contracts for a living. I found three critical logic flaws in a decentralized storage project’s token distribution mechanism. That experience taught me that code-based transparency isn’t just good engineering—it’s a moral compass. Open books, open ledgers, open hearts. When the code is public and verifiable, trust becomes a byproduct of arithmetic, not a leap of faith.
Now apply that to the Iranian airliner. Imagine a world where every commercial flight is tracked on a permissionless blockchain. Not just the flight number, but the cargo manifest, the fuel load, the payload weight—anonymized and verified by multiple oracles. Zero-knowledge proofs could confirm that the cargo is humanitarian aid without revealing its exact nature to adversaries. Both Iran and Saudi Arabia would have a shared, immutable record of what actually happened. The gray zone becomes transparent.
This isn’t science fiction. Supply chain tracking on blockchain is already happening in sectors like pharmaceuticals and diamonds. The same technology can be applied to humanitarian corridors in conflict zones. I saw the potential firsthand when I co-founded Neo-Tokyo Punks, an NFT project that bridged Edo-period art with generative AI. We negotiated digital rights with three ukiyo-e museums, creating a hybrid physical-digital asset model. The blockchain served as a cultural sovereignty layer—proving provenance without needing a centralized authority. If blockchain can preserve cultural heritage, why not preserve human life by reducing the chance of miscalculation?
Of course, the technology alone is not enough. The harder challenge is adoption by state actors who benefit from ambiguity. This is where the contrarian angle comes in.
Contrarian Angle The Counterargument: Blockchain can be used by bad actors too. Just as Iran could use a civilian plane to smuggle weapons, they could use a blockchain to camouflage the activity. After all, DeFi protocols like Aave and Compound have interest rate models that are completely arbitrary—they have nothing to do with real market supply and demand. Similarly, a malicious actor could deploy a smart contract that claims to record ‘humanitarian aid’ but actually records false information. The code is not a panacea; it’s only as good as the incentives and the community that governs it.
Moreover, the data availability (DA) layer is overhyped. 99% of rollups don’t generate enough data to need dedicated DA. For a humanitarian supply chain, the data volume is tiny. But the real bottleneck is political: states are not willing to give up the ambiguity that makes gray-zone tactics effective. Transparency is a threat to their power.
But here’s the retort: we don’t need to trust, we need to verify. Even if a state lies on the blockchain, the lie is recorded and can be audited later. The cost of lying becomes higher because the evidence is permanent. This is exactly what happened with the Tezos-based project I audited—the flaw was public, and the team had no choice but to correct it. Code is law, but ethics is life. The audit is not the end, but the beginning.

I recall my time building ChainLit, a DeFi library during the summer of 2020. I wrote 40 simplified guides, but failed because I lacked structure. That taught me that passion needs discipline. Similarly, blockchain evangelism needs pragmatic bridge-building. We can’t just argue that blockchain will solve all geopolitical problems. We need to identify where it adds the most value—in this case, in reducing the information asymmetry that fuels gray-zone escalation.
Takeaway The Iranian airliner incident is a warning shot. It shows how quickly a small event can spiral into a full-blown crisis. But it also shows an opportunity. We have the tools to build a layer of trust that transcends borders. Culture is the ultimate consensus mechanism—and we already have the protocols to encode it. The question is whether we have the will to use them.
Building bridges where others build walls. That’s the ethos. And it starts with making the invisible visible. Open books, open ledgers, open hearts. The next time a plane lands in a conflict zone, let the blockchain be the witness that everyone can trust.
