Overview
The Cardano Single Pool Alliance (CSPA) is a volunteer-run collective of Cardano stake pool operators who each commit to operating only one stake pool, promoting true decentralization across the network. The alliance counters stake concentration by encouraging a one-to-one ratio of entity to stake pool.
The CSPA operates without central authority, board members, or paid leadership. Volunteer operators coordinate through a shared commitment: when a member pool reaches saturation, the operator helps channel delegators toward other alliance pools rather than launching a second pool1. This structure reflects the alliance's core argument that an abundance of independent, single-owner pools strengthens Cardano's resilience against coordinated attacks or single points of failure.
New members join by submitting a pull request to the alliance's GitHub Registration repository, adding their pool ticker, pool ID, and contact information to a public registry2. This registry generates structured data consumed by stake pool explorers such as Cexplorer, enabling delegators to identify and filter for alliance members when choosing where to stake.
Key Features
- One-to-one operator model. Each member pledges to run exactly one stake pool, preventing multi-pool entities from concentrating network stake under a single operator1.
- Open registration via GitHub. Operators join by submitting a pull request with their pool details, making membership transparent and publicly verifiable2.
- Saturation channeling. When a member pool fills to capacity, the operator directs new delegators to other stake pool alliance members rather than creating additional pools1.
- Explorer integration. The registration data feeds directly into platforms like Cexplorer, allowing delegators to filter for alliance members in pool listings2.
- Ecosystem recognition. The Cardano Foundation has featured the alliance in its SPO Spotlight series, and the group appears on the Essential Cardano resource list maintained by IOG3.
What to Expect
The Cardano Single Pool Alliance is a community initiative rather than a software product, so the user experience centers on discovery and delegation rather than a traditional application interface. The alliance's homepage displays a live table of member pools powered by Cexplorer, showing active stake, block production, pledge, margin, and fixed fee for each operator. Delegators can browse this table to compare single-pool operators side by side before committing their stake.
For stake pool operators interested in joining, the process is straightforward: fork the Registration repository, add pool details to the registry file following the documented schema, and submit a pull request. The alliance maintains an active Telegram group for member coordination and discussion. Because the CSPA has no formal hierarchy or dues, participation is entirely voluntary and driven by shared commitment to network decentralization.
