Overview
The Cardano Single Pool Alliance is a voluntary group of Cardano stake pool operators who each promise to run only one pool. Members trade the bigger rewards that come from running many pools for the wider goal of a more spread-out Cardano. By committing to one pool each, they help make sure no single operator can quietly gather lots of stake under different names.1
There is no boss, no treasury, and no elected leadership. The alliance describes itself as a participation of the willing: any single-pool operator who agrees with the idea can say so and coordinate informally with the others. It is referenced in the official Cardano operator documentation kept by IOG as one of the recognised Cardano stake pool alliances.2
For delegators, joining costs nothing and works through any normal Cardano wallet. For operators, joining is just as light: a written commitment and a pool listing on a public file.
Key Features
- One operator, one pool. Every member promises to run a single pool and not to open more, even when their pool fills up and a second would be profitable2.
- No leaders, no central control. The alliance has no company structure, no chosen spokespeople, and no required tools. It runs on a shared commitment rather than top-down rules1.
- Redirect delegators when full. When a member pool fills up, the operator points new delegators to other members instead of launching a second pool of their own3.
- Public list of members. The alliance publishes a live roster with live pool data from community stake pool explorers like Cexplorer and PoolTool, so delegators can verify the single-pool promise themselves.
- Open-source onboarding. Operators register their pool by editing a public file on GitHub, so anyone can see who has joined, when, and with which pool.
What to Expect
The alliance works as a reference point rather than a product. Delegators who want to support a more decentralized Cardano can browse the member list, compare pool details, and delegate to any listed operator without needing to install anything or interact with a central system. There is no token to buy and no forum to join. You simply pick a listed pool through a standard Cardano wallet like Lace or Eternl.
Joining as an operator is just as light. A single-pool stake pool operator publishes their pool ticker, commits in writing to running only one pool, and submits a small registration through the public GitHub file. Because there is no shared money pot and no voting system, members have no ongoing obligations beyond honouring their pledge. In practice, the Cardano Single Pool Alliance works more like a public directory of like-minded operators than a DAO or formal organisation. The value is the curated shortlist of pools whose decentralization stance is openly stated and visible on-chain. The website is bare-bones, so think of the alliance as a community signal rather than a polished service.3
