Blockchain Hosting Servers

HOSTKEY delivers high-performance and customizable server solutions that are custom-built for blockchain or other decentralized applications. Let’s take a look at how our offerings align with the key needs of Web3 infrastructure:

Full hardware control over you bare-metal servers

HOSTKEY gives you full root access to your dedicated bare-metal servers. Take complete control over your software stack with the ability to run performance-critical blockchain nodes without virtualization overhead.

Reliable uptime in Tier III/IV Data Centers

All servers are hosted in certified data centers in Europe, the USA and Turkey, providing high availability through redundant power, cooling, and networking systems, backed by a 99.99% uptime SLA.

Our enterprise-grade specs deliver top-grade computing power

All our servers are built with powerful AMD EPYC or Ryzen CPUs, each able to hold up to 256 GB ECC RAM and all with NVMe SSDs. All this means you get ultra-fast performance for node validation, indexing and DApp backend workloads.

Security and Compliance at its core

DDoS protection by default, a suite of custom firewall options, private VLANs and secure KVM access all meet the strictest security requirements and let you rest assured that your infrastructure is shielded from outside threats.

Flexible Crypto-friendly Billing

HOSTKEY accepts payments in Bitcoin, Ethereum, USDT and other cryptocurrencies. Decentralized teams, DAOs and blockchain projects looking for frictionless payments and who appreciate quick and easy solutions to financial transactions.

DevOps & Automation ready

You can integrate your infrastructure using Terraform, RESTful APIs or other automated deployment scripts. HOSTKEY also offers custom OS pre-installations, containerization and server-image cloning.

24/7 Tech Support with deep experience in Blockchain

Our engineers have years of experience in deploying and managing blockchain nodes and a deep knowledge of Ethereum, Solana, Polygon, Avalanche, Filecoin, Arbitrum and IPFS. Get help any time with custom and instant server configurations.

World-wide coverage means low-latency access

You can deploy your nodes across Europe and North America in a growing number of DCs, letting you minimize latency and create geographic redundancy within your decentralized infrastructure.

Web3 Use Cases Requiring High-Performance Dedicated Servers from HOSTKEY

Blockchain full-node hosting

You can full nodes for networks like Ethereum, Bitcoin, Solana or Polkadot to maintain ledgers, validate transactions and generally to support network decentralization.

Validator & Staking infrastructure

Operate validators for Proof-of-Stake Blockchains (e.g., Ethereum 2.0, Cosmos, Avalanche) where uptime, low latency and hardware stability have a direct effect on your bottom line and reputation.

zk-Rollup Prover Nodes

Generate zero-knowledge proofs for zk-Rollups like zkSync, StarkNet or Scroll, all of which require high-performance GPUs (A100/H100) and CPUs optimized for computing power.

Decentralized Application (DApp) Backends

You can deploy your scalable and secure DApp infrastructure with the help of low-latency APIs that provide fast data processing and complete control over the whole environment.

Blockchain Data Indexing & Analytics

The Graph, SubQuery or custom ETL pipelines to index blockchain data – you can do them all. These require a fast NVMe I/O and huge amounts of RAM to perform real-time analysis.

IPFS / Filecoin Storage Nodes

Host InterPlanetary File System (IPFS) or Filecoin nodes to serve decentralized content, store Web3 assets or provide high bandwidth hosting.

Custom RPC Nodes / Infrastructure-as-a-Service

Offer private RPC endpoints for developers and applications needing stable, fast and isolated blockchain access with customizable throughput and latency.

DeFi Protocol Infrastructure

Run the infrastructure behind DeFi platforms such as DEXs, aggregators or lending protocols that demand a low downtime and premium transaction security.

DAO Backend and Governance Tools

Power your backend services for Decentralized Autonomous Organizations (DAOs). You can do it all - from voting systems, token management to smart contract execution.

Web3 AI and ML Computation

Integrate your AI models into Web3 with the raw power of RTX 4090 or H100 GPUs for tasks like NFT generation, LLM-based smart contract analysis or even for decentralized AI agents.
