• Summary: Wasabi is the clean coordinator-run CoinJoin baseline in the corpus. The important part is not privacy wallet branding; it is the way WabiSabi lets a coordinator verify value conservation without learning the direct input-output map. That pushes attention to the real control surfaces: coordinator policy, round admission, credential flow, Tor-separated identities, and wallet-default post-mix discipline.
• What it does:
  • Implements non-custodial Bitcoin CoinJoins through a centrally coordinated WabiSabi protocol where participants register inputs and outputs without giving the coordinator a direct input-output mapping
  • Uses variable-amount credentials and credential reissuance so users can decompose value privately instead of relying only on fixed equal-output denominations
  • Routes coinjoin participation through Tor and creates fresh network identities for input registration and output registration phases to reduce linkability at the coordinator layer
  • Bundles coinjoin participation into a desktop wallet that also provides private block synchronization, labeling, privacy suggestions, coin control, RPC access, and hardware-wallet-adjacent storage features
  • Lets users configure coordinator selection and fee thresholds while the coordinator still controls round timing, mining-fee policy, minimum input conditions, and operational admission rules
  • Treats CoinJoin as a background wallet process rather than a specialist trading market, with automatic or semi-automatic participation once wallet conditions are met
• Key claims:
  • Wasabi clears the bar because it is not just another Bitcoin wallet with a privacy tab. The WabiSabi paper and Wasabi docs expose a specific split between a central round coordinator, anonymous credential machinery, Tor-isolated communication identities, wallet-level privacy policy, and user-held signing authority.
  • The WabiSabi mechanism is the core reusable insight. Instead of enforcing only equal-output pools, the protocol uses keyed-verification anonymous credentials and homomorphic value commitments so the coordinator can verify conservation of value while staying unable to link inputs to outputs.
  • Wasabi’s trust model is narrower than a generic hosted mixer. The docs are explicit that the coordinator cannot steal funds because users verify and sign the final transaction locally, but coordinator policy still shapes who gets admitted, when rounds complete, what fee conditions are acceptable, and how much metadata the service can observe at the operational edge.
  • Tor separation is part of the protocol surface, not merely transport hygiene. The docs describe separate Alice and Bob identities so cleartext inputs and cleartext outputs are not trivially linkable by the coordinator.
  • Wasabi is productively different from JoinMarket. JoinMarket exposes a market for maker inventory and sybil-resistant liquidity, while Wasabi packages coordinator-run CoinJoin into a default wallet flow where the main power centers are coordinator policy, protocol design, and wallet heuristics rather than maker pricing.
  • Wasabi also has to be read as a full privacy stack, not just a round coordinator. Compact-filter synchronization, labeling, payment suggestions, and coin control all shape whether the privacy gained from CoinJoin survives after the round finishes.
  • The current fee model is analytically relevant: recent docs say the client will only join rounds where it pays mining fees rather than coordinator fees, which makes the fee surface more about coordinator policy and blockspace costs than about a direct marketplace for privacy liquidity.
• Whitepaper: The clearest technical primary source is the WabiSabi paper, WabiSabi: Centrally Coordinated CoinJoins with Variable Amounts, together with the official Wasabi site, docs, and repository; see ../whitepapers/wasabi-primary-sources-2026-05-15.md.
