The Stacks blockchain is redefining what’s possible with Bitcoin by extending its capabilities beyond simple value transfer. As a Layer 2 solution built directly on Bitcoin, Stacks unlocks smart contract functionality and enables fast, low-cost transactions—all while inheriting Bitcoin’s unmatched security and decentralization. This makes it an ideal platform for developers and enterprises looking to build decentralized applications (dApps) that are secure, scalable, and deeply integrated with the world’s most trusted cryptocurrency.
Deploying your own Stacks node is a powerful way to connect directly to the network, validate transactions independently, and support the ecosystem’s growth. With Amazon Web Services (AWS), you can deploy and manage Stacks nodes efficiently using the open-source AWS Blockchain Node Runners initiative. This guide walks you through deploying Stacks nodes using the AWS Node Runners blueprint, covering both single-node and highly available (HA) configurations.
Understanding the Stacks Blockchain Architecture
Stacks operates on a unique consensus mechanism called Proof of Transfer (PoX), which ties its security directly to Bitcoin. Instead of modifying Bitcoin’s protocol, Stacks leverages it as a settlement layer. Here's how it works:
- Miners bid Bitcoin to earn the right to mine new Stacks blocks and receive newly minted STX tokens as rewards.
- Signers (validators) lock up STX tokens to verify block validity and maintain consensus. In return, they receive the Bitcoin spent by miners.
- Followers download the blockchain, verify transactions independently, and serve as RPC endpoints for dApps.
This three-tier architecture ensures decentralization, security, and accessibility. By running a follower node—either standalone or in a high-availability setup—you gain direct access to the Stacks network without relying on third-party services.

Solution Overview: AWS Blockchain Node Runners for Stacks
The AWS Blockchain Node Runners blueprint simplifies the deployment of full Stacks nodes on AWS. It automates infrastructure provisioning, configuration, and monitoring, allowing developers and enterprises to focus on building applications rather than managing servers.
Key benefits include:
- Automated deployment via AWS CloudFormation templates
- Built-in integration with AWS security and monitoring tools
- Support for both testnet and mainnet environments
- Flexible deployment options: single node or highly available follower setup
Currently, the blueprint supports deploying follower nodes in two configurations:
- Single-node deployment – ideal for development, testing, or lightweight production use
- Highly Available (HA) deployment – designed for mission-critical dApps requiring uptime and redundancy
Future updates will expand support to miner and signer node types.
Deploying a Single Stacks Node on AWS
A single-node deployment is perfect for developers who need a reliable RPC endpoint for dApp testing, smart contract interaction, or transaction validation.
Deployment Workflow
- Infrastructure Setup: The Stacks node launches within the default Virtual Private Cloud (VPC) and connects to the broader Stacks network via an internet gateway.
- Secure Access: The node is accessible internally to other resources in the VPC. The JSON-RPC API is not exposed to the public internet, enhancing security.
- Secrets Management: Sensitive credentials and configuration data are stored locally and backed up securely in AWS Secrets Manager.
- Monitoring & Observability: Key performance metrics from both the EC2 instance and the Stacks node are streamed to Amazon CloudWatch, enabling real-time monitoring and alerting.
This setup minimizes operational overhead while ensuring secure, stable connectivity to the Stacks blockchain.
Building a Highly Available Stacks Node Cluster
For production-grade applications where uptime and resilience are critical, AWS offers a highly available (HA) deployment pattern using Auto Scaling and Load Balancing.
HA Architecture Components
- Auto Scaling Group: Manages a dynamic pool of EC2 instances running Stacks nodes. If one node fails, it's automatically replaced.
- Application Load Balancer (ALB): Distributes incoming RPC requests across healthy nodes, ensuring consistent performance and failover capability.
- Private Subnet Deployment: All nodes operate within private subnets in the default VPC, isolated from direct internet access.
- CloudWatch Integration: Comprehensive monitoring tracks node health, synchronization status, and system resource usage.
Why Choose HA?
Running multiple synchronized follower nodes behind a load balancer increases fault tolerance and reduces downtime. This architecture is especially valuable for:
- Enterprise dApps serving large user bases
- Wallet providers requiring uninterrupted blockchain access
- Indexing services and blockchain explorers

Recommended Hardware Specifications
To run a Stacks mainnet node effectively, adhere to community-recommended specifications:
- Disk Space: 512 GB (SSD recommended for faster sync times)
Instance Types:
- c4.4xlarge: Offers superior compute performance for faster block processing
- m5.large: Meets minimum vCPU requirements; suitable for lighter workloads
While m5.large is cost-effective, c4.4xlarge is preferred for production environments due to its higher throughput and I/O efficiency.
Tips for Optimal Performance
- Use provisioned IOPS SSD volumes for faster blockchain synchronization
- Enable automatic snapshot backups using Amazon EBS
- Monitor disk usage closely—blockchain data grows over time

Frequently Asked Questions (FAQ)
Q: Can I deploy miner or signer nodes using the AWS Node Runners blueprint?
A: Not currently. The blueprint currently supports only follower node deployments—both single and HA setups. Support for miner and signer configurations is planned for future releases.
Q: Is the JSON-RPC API exposed to the public internet?
A: No. For security reasons, the RPC endpoint is only accessible within the VPC or through secure internal routing. You can extend access via API Gateway or private endpoints if needed.
Q: How long does it take to sync a new Stacks node?
A: Initial synchronization time varies based on instance type and disk speed. With a c4.4xlarge and SSD storage, expect full sync within several hours to a day.
Q: What happens if my node goes offline in an HA setup?
A: The Auto Scaling group detects unhealthy instances and automatically launches replacements. The load balancer routes traffic only to healthy nodes, ensuring seamless continuity.
Q: Are there ongoing costs after deployment?
A: Yes. You’ll incur standard AWS charges for EC2 instances, EBS storage, data transfer, and optional services like CloudWatch and Secrets Manager.
Q: Can I use this setup for testnet development?
A: Absolutely. The blueprint supports both mainnet and testnet configurations, making it ideal for end-to-end development workflows.
Conclusion
Deploying Stacks blockchain nodes on AWS using the Blockchain Node Runners blueprint offers a secure, scalable, and automated path to participating in the Bitcoin-powered smart contract ecosystem. Whether you're building a simple prototype or a high-traffic dApp, AWS provides the tools to run reliable, production-ready nodes with minimal effort.
By hosting your own infrastructure, you enhance decentralization, reduce dependency on third parties, and gain full control over your blockchain interactions. As the Stacks ecosystem evolves—and future support for miner and signer roles becomes available—AWS will remain a foundational platform for innovation in the Bitcoin Layer 2 space.
