• Summary: Geyser is Bitcoin-and-Nostr crowdfunding infrastructure with a Rootstock-backed all-or-nothing contract path underneath it. The useful part is not generic creator-economy rhetoric; it is the attempt to move campaign custody and refund logic out of the platform and into contract-enforced release conditions while Geyser still handles discovery, launch, and social reach.
• What it does:
  • Lets creators and communities launch Bitcoin-native crowdfunding campaigns and fund humanitarian or open-source projects
  • Builds fundraising on top of Bitcoin, Lightning, and Nostr rather than only on a closed platform identity/payment stack
  • Supports all-or-nothing campaigns with a funding goal, campaign deadline, locked contributions, and automatic refund eligibility if the goal is missed
  • Uses an open-source smart contract on Rootstock for non-custodial campaign enforcement, with rules around release and refund handled by contract logic rather than by Geyser custody
  • Publishes an open-source app repo and local-development workflow, which makes the platform look more like reusable open fundraising infrastructure than a thin marketing frontend
• Key claims:
  • The homepage presents Geyser as “Bitcoin Crowdfunding for New Ideas and Humanitarian Causes”
  • The official app README says Geyser is a “bitcoin & nostr native crowdfunding platform” where users can fund project ideas with support from global communities
  • That same README says Geyser is enabling an “Open Creator Economy” by building fundraising on top of Bitcoin/Lightning and Nostr instead of closed monetary and social networks
  • The README also says Geyser is an open company that builds open-source software, and the repo exposes a real staging API, local-development flow, and architecture/contribution materials
  • The all-or-nothing campaign guide says campaign creators set a funding goal and time window, contributions remain locked until the campaign ends, funds are released only if the goal is reached, and otherwise contributors can recover funds
  • The all-or-nothing guide says this model is powered by an open-source smart contract on Rootstock, that neither Geyser nor the creator can access funds unless the funding goal is reached, and that refund logic is enforced by the contract itself
• Whitepaper: No canonical standalone Geyser whitepaper or litepaper surfaced in this pass. The clearest current sources of truth were the official site, the open-source app repository, and the official campaign guide describing Rootstock-based all-or-nothing flows; see ../whitepapers/geyser-primary-sources-2026-05-02.md.

Internal linkages

• Strongest structural reads: opensats and btcpay-server.

Governance / control risk

• The contract trims custody risk, but Geyser still controls the discovery layer, launch workflow, and a lot of the practical social distribution.

• Useful crowdfunding infrastructure, not neutral public plumbing.
