Where do your blockchain nodes actually run?

Most developers don’t think twice about this question. They spin up a validator on AWS, deploy their dApp infrastructure on Google Cloud, or grab a managed node from a popular Web3 node provider. It works, it’s fast, and to be honest, no one is asking questions. But, what’s the most awkward part? “The decentralized” blockchain world is running on some of the most centralized infrastructure in the world.

December 2024 proved this in a painful way. AWS’s US-East-1 region went down, and 40% of Ethereum validators went with it. Transactions froze. Networks stuttered. The whole thing laid bare a reality many in crypto would rather ignore. When your decentralized network relies on centralized hosting, you are one outage away from chaos.

It is a fact that about 65% of Ethereum nodes and 80% of Solana validators rely on centralized cloud hosting. It is not decentralization. It’s centralization with blockchain middleware. The question isn’t whether this is important; it’s whether anyone cares enough to change it before the next big failure.

According to blockchain researchers, a high percentage of Bitcoin nodes are located in only three countries: the US, Germany, and France. When you give it a closer look, you see how worse the situation is. Most of these blockchain nodes are located in a few data centers owned by the same companies.

When developers choose Node as a Service platforms from major cloud providers, they’re handing control to entities that can shut things down whenever regulations, business decisions, or technical failures demand it. One natural disaster, one government order, one bad day at a data center, and a massive chunk of supposedly distributed infrastructure vanishes.

Cloud companies are accountable to governments, not blockchain values. This was made clear in March 2025 when the EU proposed tougher crypto infrastructure regulations. Blockchain node providers running on AWS’s Frankfurt servers suddenly faced surveillance requirements and potential shutdown orders. Projects realized too late that “censorship-resistant” doesn’t mean much when your infrastructure lives where regulators can reach it.

The bigger issue? Regulatory action against one cloud provider can wreck dozens of blockchain networks simultaneously. That’s not a theoretical risk anymore; it’s a demonstrated vulnerability.

What does using a Web3 node provider on centralized infrastructure really means? You’re not just betting on the blockchain working, you’re betting on AWS’s DNS, Google’s storage systems, and Azure’s networking all working too. f there is any weak link in this chain, your nodes will go down, irrespective of whether the blockchain is healthy or not.

Google Cloud had a massive global outage for several hours on June 12, 2025. This had a severe effect on Web3 and blockchain. Many dApps were affected, not because Ethereum, Solana, or any other chain was not healthy, but because they all relied on the same infrastructure. One company’s infrastructure problem became everyone’s problem.

Plenty of teams think they’ve solved this by spreading nodes across multiple availability zones. Different data centers, and different physical locations look good on paper. Except those zones share the same power grids, network backbones, and management systems. A provider-level failure still kills everything.

Real redundancy means using different infrastructure providers entirely, not just different corners of the same Web3 node provider’s empire. Anything less is backup copies in different drawers of a filing cabinet that’s about to catch fire.

Have you built your infrastructure deep enough into AWS or Google Cloud? If yes, then custom networking, managed databases, proprietary monitoring, and migration becomes nearly impossible. When an outage hits or a security incident unfolds, that lock-in means you can’t failover to alternative infrastructure quickly enough to matter.

Projects using tightly integrated Node as a Service solutions discover this the hard way. They can’t just spin up replacement nodes on different providers without weeks of reconfiguration. During a crisis, weeks might as well be years.

Smart contracts operate well on decentralized blockchains. When blockchain nodes run on centralized servers, it becomes difficult for users to actually use those contracts at times. 

Let’s talk about Uniswap, one of the most renowned decentralized exchanges. In late 2024, the majority of users interacted with Uniswap via web interfaces that were hosted on traditional cloud infrastructure, which in turn relied on blockchain node providers who mostly used AWS infrastructure. What happens if AWS cuts access tomorrow? Those “permissionless” protocols become pretty hard to access. The smart contracts still exist somewhere on-chain, but good luck interacting with them without the infrastructure layer.

Oracles get criticized for introducing centralization. Bringing off-chain data onto blockchains requires trusting someone, and it’s a fair point. But there’s a deeper problem: when blockchain nodes run on centralized platforms, applications trust those platforms to faithfully relay blockchain data.

Could a compromised cloud provider manipulate responses, censor transactions, or feed false information to applications? Theoretically, yes. Practically, that trust relationship exists whether developers acknowledge it or not. All the cryptographic guarantees in the world don’t help if the infrastructure providing access to the blockchain is untrustworthy.

Nobody wants to say it at conferences, but centralized hosting wins because it’s easier. AWS provides one-click deployment, autoscaling, monitoring, and a support number to call when things go wrong. Decentralized infrastructure means coordination of multiple cloud services, debugging weird networking issues, and trading reliability for now.

Startups racing to ship features and find users make the obvious choice. “We’ll decentralize later” becomes the refrain. Later never comes. Infrastructure decisions made for short-term convenience turn into permanent architecture.

Blockchain projects sell themselves on censorship resistance. No government can shut down the protocol, no corporation controls the network, except the protocol is only as censorship-resistant as the weakest infrastructure link.

February 2025 demonstrated this clearly. Several countries pressured cloud providers to restrict crypto services. Projects on those platforms watched their “unstoppable” applications get stopped, not by attacking the protocol, but by cutting access at the infrastructure level. The protocol remained uncensored. The infrastructure didn’t.

Even perfectly encrypted blockchain transactions leave metadata trails when hosted on centralized infrastructure. Users hitting dApps through AWS-hosted nodes give that cloud provider IP addresses, access patterns, and usage data. The transaction contents might be private, but the metadata reveals plenty.

Web3 node provider services on centralized platforms create surveillance possibilities that directly contradict blockchain’s privacy promises. Zero-knowledge proofs protect the transaction data while AWS tracks exactly who’s accessing what and when.

Instanodes distributes blockchain nodes across genuinely independent infrastructure providers. Unlike conventional Node as a Service offerings based on AWS or Google Cloud, Instanodes distributes nodes over bare-metal servers, separate data centers, and hosting companies that do not share common ownership.

If a provider goes down, the others remain operational. If a region faces regulatory pressure, nodes in other regions remain operational.

Instanodes doesn’t just deploy nodes in different availability zones of the same cloud provider. The nodes are spread across various continents, jurisdictions, and network infrastructures. A node in Singapore operates on a completely different infrastructure than one in Iceland or Brazil.

The outage in December 2024, which affected 40% of Ethereum validators on AWS, would not have affected Instanodes’ infrastructure since none of it is dependent on AWS.

The problem with traditional blockchain node providers is that they lock projects into particular infrastructure stacks, which makes it very painful to migrate. Instanodes has open standards and portable configurations that are portable across different providers. Need to shift the load away from a particular region? It takes minutes, not weeks.

Most Web3 node provider services follow AWS’s playbook: scale up, drive down costs through volume, capture market share. Instanodes takes a different approach. The economic system of the platform is one that encourages diversity over consolidation.

We are working with independent infrastructure providers, which ensures that the infrastructure space remains healthy and diverse.

Most developers choose centralized Node as a Service platforms because they’re easier to use. Instanodes provides the same quality of developer experience—clean APIs, comprehensive monitoring, reliable uptime, and responsive support without forcing developers to accept centralized infrastructure.

Developers get a single interface to manage nodes distributed across multiple providers. The complexity of truly decentralized infrastructure gets handled behind the scenes.

The gap between blockchain’s promises and its infrastructure reality keeps growing. Projects talk about decentralization while running on the same centralized cloud platforms that power traditional tech. The contradiction isn’t sustainable.

Centralized hosting created real vulnerabilities. December 2024’s AWS outage proved it. The regulatory pressure in early 2025 confirmed it. The question isn’t whether this centralization poses risks, the risks are documented. The question is what gets done about it.

Instanodes demonstrates what blockchain infrastructure looks like when it matches blockchain principles. Multi-provider infrastructure means no single point of failure. True geographic distribution protects against localized disruptions. Transparent dependencies let projects make informed choices about infrastructure risk.

It’s a simple choice: continue down the path of building on top of centralized infrastructure and hope that the vulnerabilities don’t come back to bite you, or build the infrastructure that actually lives up to the promises of decentralization.

Your infrastructure defines your decentralization. Running blockchain nodes on AWS doesn’t make a project decentralized. it just makes them an AWS customer with blockchain middleware. Decentralization means infrastructure that can’t be shut down by the failure of one company, the regulation of one government, or the disaster in one region.

Instanodes provides Node as a Service built on genuinely distributed infrastructure. Independent providers across multiple continents. No single point of failure. No vendor lock-in. No centralized control hiding behind decentralized marketing.
