Is Sawtooth a Viable Long-Term Solution on AWS?
An interactive summary of the key findings and final recommendation.
Recommendation: Not Recommended
For new, mission-critical enterprise deployments on AWS, Hyperledger Sawtooth is **not recommended** as a long-term private blockchain solution due to significant risks related to project stability, operational overhead, and performance limitations.
Key Risk Factors at a Glance
Archived Project Status
Officially archived by Hyperledger, raising concerns about long-term support, security, and community viability.
High Operational Overhead
No managed AWS service exists. Requires full self-management, increasing TCO, complexity, and internal resource strain.
Scalability Limitations
Empirical data shows low throughput (e.g., ~25 TPS with PBFT) that can decrease as the network grows.
Superior Alternatives
Hyperledger Fabric on Amazon Managed Blockchain offers a lower-risk, more scalable, and operationally efficient solution.
Project Health: A Timeline of Transition
Sawtooth's journey from a premier Hyperledger project to a community-maintained one is a key factor in its risk profile. This transition marks a significant decrease in broad industry backing.
Initial Backing & Growth
As a key Hyperledger project, Sawtooth was sponsored by major corporations like Intel and IBM, gaining significant traction and contributions within a large, stable ecosystem.
Archived by Hyperledger
At the maintainers' request, the project was officially moved to "archived" status, signaling the end of active development and support under the Linux Foundation's Hyperledger umbrella.
Transition to Splinter
Maintenance and future development shifted to the Splinter community, a smaller, more niche group focused on privacy-preserving distributed applications. The project's future is now tied to this new, less-established ecosystem.
Community Release: Sawtooth 1.2
The Splinter community released Sawtooth 1.2, demonstrating continued maintenance. However, the scale of this community and its long-term funding and support remain significant open questions for enterprise adopters.
The AWS Operational Reality
The lack of a managed service on AWS is a critical operational and financial differentiator. Here's a comparison of the effort required for Sawtooth versus the recommended alternative, Hyperledger Fabric.
Self-Managed Sawtooth on EC2
High Manual Effort
You are responsible for provisioning, configuring, monitoring, patching, scaling, and securing all nodes and network components.
Higher TCO
Costs include raw infrastructure plus significant investment in specialized DevOps and blockchain engineering talent.
Increased Security Risk
Self-managed resources are a common target. Misconfigurations can lead to significant vulnerabilities and data breaches.
Managed Fabric on AMB
Low Manual Effort
AWS handles underlying infrastructure management, security, and scalability, allowing you to focus on application logic.
Lower TCO
Predictable pricing and reduced need for a large, specialized operational team lower the total cost of ownership.
Reduced Security Risk
Leverages AWS's robust security posture, compliance certifications, and managed security services.
Performance & Technical Trade-offs
Sawtooth's performance is highly dependent on the chosen consensus algorithm. This creates critical trade-offs between speed, finality, and fault tolerance that enterprises must navigate.
PBFT Throughput Limitation
Empirical data shows a maximum throughput of ~25 transactions per second for a 4-node PBFT network, a potential bottleneck for enterprise applications.
