Blockjoy

BlockJoy is a Web3 infrastructure company that builds managed node deployment and management software for blockchain operators. Its flagship product, BlockVisor, allows enterprises to deploy and operate blockchain nodes — including validators, RPC nodes, and ETL pipelines — on any bare-metal server infrastructure, dramatically cutting operating costs compared to traditional cloud providers. The company's tagline sums up its division of responsibility: "You deploy, we manage."

The Problem

Running production blockchain nodes on cloud infrastructure like AWS is expensive. A validator or RPC node consuming significant compute, memory, and storage can cost upwards of $200 per month on AWS, and cloud pricing compounds at scale. Beyond cost, managed cloud services abstract away control: operators cannot tune hardware, networking, or VM parameters to match the specific demands of high-throughput chains like Solana. BlockJoy was built to solve both problems simultaneously.

How BlockVisor Works

BlockVisor is BlockJoy's patented node management platform. Rather than relying on managed cloud VMs, it runs blockchain nodes inside lightweight Firecracker microVMs on bare-metal servers that operators own or rent directly. BlockJoy built firec, an open-source Rust API for interacting with Firecracker, and uses it as the foundation for node isolation and lifecycle management.

The architecture has four components:

• BlockVisor API: A centralized service managing metadata for protocols, nodes, hosts, and organizations.
• BlockVisor Daemon: A host-level agent that runs on each bare-metal machine, communicating with the API through MQTT to coordinate node operations.
• BlockVisor Protocols: Code-defined specifications that encode each chain's runtime parameters, resource requirements (CPU, memory, disk, firewall settings), and custom configurations.
• BlockVisor Frontend: A point-and-click web interface for node management, host onboarding, and organization setup.

Together, these components allow operators to deploy consistent, isolated node environments across any bare-metal infrastructure — private data centers, co-location facilities, or dedicated server providers — without writing custom automation for each chain. A self-hosted deployment runs the full stack via Docker Compose with built-in observability through Prometheus, Grafana, Loki, and Tempo.

BlockVisor 2.0

BlockJoy shipped BlockVisor 2.0 as a major platform upgrade focused on bare-metal-native performance and cost efficiency. The new version delivers claimed 10x throughput improvements over running nodes on Amazon's Firecracker-based cloud VMs, and reduces operating costs by 2-3x relative to AWS. The company reported adding 524 new nodes within three months of the 2.0 launch and added nearly $500,000 in new annual recurring revenue in the same period. Early adopters of the updated platform included Goldsky, 0x, and TrueBlocks.

Supported Protocols

BlockJoy's protocols repository provides containerized blockchain node implementations for 20+ networks including Ethereum, Avalanche, Near, Sui, Cosmos, Arbitrum One, Arbitrum Nova, Optimism, Polygon, Base, Blast, Axelar, Kaia, and others. Solana has been supported since the platform's early days and is explicitly listed among the chains BlockVisor manages. The company separately maintains agave-monitor, an open-source tool that scrapes and exposes Solana/Agave validator metrics to Prometheus-compatible monitoring stacks including Grafana, Alloy, Vector, and Promtail — giving Solana validator operators granular visibility into validator health alongside system-level metrics like CPU, memory, and disk usage.

Team and Funding

BlockJoy was founded in 2021 by CEO Chris Bruce, a four-time founder, and CTO Sean Carey, who previously co-founded Helium Inc., the IoT blockchain network that reached a $1.2 billion valuation. The two started BlockJoy after struggling with the cost and complexity of running their own staking infrastructure. The company's early traction came organically: within six months of launch it was managing 1,200 validators for the Helium Network.

BlockJoy has raised $12 million across combined seed and Series A rounds. Investors include Gradient Ventures (Google's AI-focused venture fund), Bessemer Venture Partners, Tribe Capital, Draper Dragon, Dragon Roark, Active Capital, Borderless HNT, and Renegade Ventures. Enterprise clients have included Binance, Crypto.com, and Helium Foundation.

Solana Fit

Solana validators impose demanding hardware requirements — high-bandwidth NVMe storage, significant RAM, and consistent sub-second response times. Running those requirements on cloud virtual machines introduces latency variability and cost overhead that erodes validator economics. BlockJoy's bare-metal model is a natural match: operators retain full hardware control, eliminate cloud markup, and can tune machine configuration for Solana's specific I/O and networking demands.

The agave-monitor project reflects an active investment in the Solana ecosystem specifically. It integrates with the Agave validator client (the codebase maintained by Anza) and surfaces validator-specific metrics through standard observability tooling, giving Solana node operators the same monitoring stack they would use for any other infrastructure component.

As of mid-2026, BlockJoy's primary public presence is its GitHub organization (github.com/blockjoy), where protocol definitions continue to be actively maintained and updated.
