Cisco, Foxconn, Bosch, Gemalto, blockchain startups, and others form an alliance to develop blockchain-based security protocol for IoT devices
The Internet of Things (IoT) - the vast web of connected devices which is becoming a fundamental part of the technological infrastructure that surrounds us …
Context & Ripple Effects
This alliance is the second standards body Cisco has joined in under a year: the company was already a founding member of the Open Connectivity Foundation with Microsoft, Qualcomm, Intel, and Samsung, which set out to make IoT devices interoperate. The new group attacks a different layer — not whether devices talk to each other, but whether they can prove what they are, using a distributed ledger as the trust mechanism.
It also lands mid-arc on two fronts. Bosch had just opened its own IoT cloud service to outside customers, giving it a platform this protocol could secure, and within months IBM would show the enterprise appetite for ledger-based trust with its blockchain collaboration with Walmart, Unilever, and Nestlé on food supply chains.
First-order effects
- Gemalto, whose business is device identity and security hardware, gains a seat defining how billions of devices authenticate — a direct extension of its core product into protocol design.
- Bosch can wire the protocol into the IoT cloud platform it began offering externally in 2017, making security a feature of its services pitch rather than a bolt-on.
Second-order effects
- Rival consortia face pressure to answer: the Open Connectivity Foundation's interoperability agenda now has a parallel security track run by an overlapping but distinct membership, raising the odds of duplicated or conflicting specifications.
- Blockchain startups in the alliance get industrial-scale validation beyond financial pilots, strengthening the case enterprises like IBM's food partners were already testing for ledgers outside finance.
Third-order effects
- If consortium-built protocols become the norm, device security shifts from each vendor's proprietary stack to certified, shared trust layers — the direction the Connectivity Standards Alliance later formalized with its globally recognized IoT cybersecurity certification.
- The proliferation of overlapping IoT alliances (connectivity, cloud, now blockchain security) points toward eventual consolidation or regulatory pressure for a single recognized standard, since manufacturers cannot certify against every body indefinitely.
The trend: IoT security is migrating from vendor-by-vendor engineering to multi-company consortium standards, with distributed ledgers emerging as one candidate for the device-identity trust layer.
