Telcos And Blockchains Just Make Sense

In recent years there has been a noticeable movement of telecommunications giants joining the blockchain space. For eagle-eyed watchers, the question shouldn’t be why, but why hasn’t it happened before. For both, it’s a relationship that works.

In the past six months, two major telecommunications companies have joined Theta Network as enterprise validators. Deutsche Telekom joined us last year, and also runs validators across Ethereum, Polkadot, and Chainlink. NTT Digital, part of Japan’s largest telco with $100 billion in annual revenue, operates validators on both Theta and Injective, and joined us earlier this week.

For many, this raises the question: why are companies that run traditional networks now running blockchain networks too?

Telcos Already Run Networks, Blockchain Networks Need Operators

Public blockchains require secure, scalable and highly redundant physical infrastructure to function:

• Always-on servers in multiple locations
• High uptime and redundancy
• Security operations teams
• Network monitoring expertise

Telecom companies already do all of this. They run data centers with 99.999% uptime targets. They have security protocols refined over decades. They employ teams that handle network operations around the clock.

Running validator nodes lets telcos reuse existing data center capacity and staff while earning staking yields that often exceed traditional telecom returns. They also gain early insights and influence in blockchain projects that may become strategic infrastructure in the future.

From a telco executive’s perspective, the decision is practical rather than ideological. When you already own the machines and employ the people, why not generate an additional revenue stream from them?

Deutsche Telekom’s Dirk Roeder put it clearly when he said they were “impressed by Theta EdgeCloud use cases focused on reliability, performance and security.” Blockchain networks need the same operational discipline that telcos have already mastered.

Hybrid Infrastructure Matches How Telcos Already Operate

Architecture like Theta’s is interesting to telecom companies because it mirrors how they already work.

Mobile networks have never been purely centralized or purely distributed; they combine centralized core systems for authentication and billing, distributed cell towers for local coverage, and edge devices that process data closer to users for lower latency.

Theta EdgeCloud works in a similar way. Cloud partners provide high-end GPU clusters for demanding workloads, while over 30,000 distributed edge nodes contribute compute capacity. An intelligent coordination layer routes jobs to whatever infrastructure makes sense for each specific task.

For telcos, this model is familiar territory as they already understand how to operate systems that balance centralization and distribution based on what each workload needs.

For Chains, Validator Credibility Matters

When major telecommunications companies validate a blockchain network, corporate partners evaluate that network differently.

Seeing Deutsche Telekom and NTT Digital in the validator set alongside Google, Samsung, and Sony signals infrastructure trusted by companies that stake their reputations on reliability.

This matters for our Theta EdgeCloud’s customer base, and the customer base of other blockchain-based networks. Universities making multi-year AI research commitments need confidence the network will remain stable. Sports organizations deploying AI agents need assurance about uptime. Enterprises evaluating decentralized infrastructure want to see trusted names operating it.

The credibility enhancement works both ways. Telcos gain hands-on experience with distributed systems and token economics that might define the next generation of infrastructure. By participating now, they develop internal expertise and position themselves as providers for whatever hybrid models emerge in the future.

Revenue From Existing Assets

Running validators generates measurable returns from infrastructure that already exists. Networks need security and decentralization, while operators with data center capacity can provide both while earning yields.

Validator operations require technical integration and ongoing maintenance. When companies like Deutsche Telekom and NTT Digital make these commitments, they signal that they view decentralized infrastructure as something worth integrating into their operations rather than watching from the sidelines.
