The blockchain industry talks endlessly about decentralization. Yet when you examine the infrastructure layer—the physical machines that validate transactions, produce blocks, and secure billions in staked assets—you find a troubling concentration. Over 65% of Ethereum validators run on three cloud providers: AWS, Google Cloud, and Hetzner. This is not decentralization. It is a distributed application running on centralized infrastructure.
At 01node, we operate differently. Every server we run sits in hardware we own, in facilities we control, connected through our own autonomous system (AS211396). This is not a philosophical choice—it is an operational imperative rooted in the architecture of trust.
The Cloud Dependency Problem
When a validator operator leases a virtual machine from AWS, they inherit a chain of dependencies. Their uptime depends on Amazon’s infrastructure decisions. Their data sovereignty is subject to Amazon’s terms of service. A single policy change, a compliance dispute, or a regional outage can take hundreds of validators offline simultaneously.
We saw this in practice during the Hetzner incident of 2022, when the provider updated its terms to prohibit cryptocurrency mining and staking. Validators had 24 hours to migrate or face termination. The Solana network, heavily concentrated on Hetzner, faced existential centralization risk overnight.
This is not a theoretical concern. It is an architectural vulnerability baked into the foundation of networks that claim to be censorship-resistant.
What Bare Metal Actually Means
Bare metal is not just “dedicated servers.” At 01node, bare metal means:
Owned network: AS211396 with BGP peering at major internet exchanges, 20Gbps+ aggregate bandwidth.
Owned facility access: Physical presence in Tier III TIA-942 rated facilities in Bucharest with biometric access control.
Owned supply chain: We spec, procure, rack, cable, and configure every machine ourselves.
This vertical integration eliminates the cloud provider as a single point of failure. No terms of service can shut us down. No provider outage can cascade across our validator set. No compliance action in a foreign jurisdiction can affect our operations.
Performance Implications
Beyond the sovereignty argument, bare metal delivers measurable performance advantages for validator operations. Hypervisors introduce latency. Shared I/O buses create contention. Network virtualization adds overhead to every packet.
Our benchmarks show 40–60% lower p99 latency on block signing operations compared to equivalent cloud instances. For high-throughput chains like Solana and Sui, where missed slots directly impact rewards and network health, this difference compounds into significant operational advantage.
NVMe storage accessed directly through the hardware controller, without a virtualization layer, delivers 3–5x higher IOPS during state sync operations. This means faster catch-up after maintenance windows and more reliable archive node operations.
The Economics of Sovereignty
Cloud infrastructure is priced for convenience, not efficiency. A comparable cloud instance to our bare metal validators costs 3–4x more on a monthly basis. Over a 3-year hardware lifecycle, the total cost of ownership for bare metal is roughly 60% lower than cloud equivalents.
This cost efficiency translates directly to validator economics. Lower operational costs mean we can maintain competitive commission rates while investing in redundancy, monitoring, and hardware refresh cycles that cloud-dependent operators cannot afford.
The Path Forward
We believe the next phase of blockchain infrastructure maturity requires a return to physical-layer sovereignty. Not every operator needs to own their hardware—but the ecosystem needs a critical mass of operators who do, to ensure that no single corporate entity holds veto power over a supposedly decentralized network.
At 01node, infrastructure sovereignty is not a marketing claim. It is the foundation of everything we build. From AS211396 in Bucharest, we validate for 40+ networks with zero slashing events, 99.99% uptime, and complete independence from cloud providers.
The future of decentralization is not in the cloud. It is in the metal.
