    "What problem do Bitcoin L2s solve, and where does BitVM fit among them?",
    "How does BitVM verify off-chain computation using today’s Bitcoin (high level)?",
    "What can BitVM-style designs unlock first: bridges, rollups, vaults, or oracles?",
    "What trade-offs matter most: interactivity, dispute latency, engineering complexity, and liveness?",
    "What adoption signals should users and builders watch to separate hype from working systems?"
  ],
  "quickSteps": [
    "Map your goal (payments, programmability, bridges, app logic) to the right L2 approach.",
    "Understand the BitVM dispute model: commitments up front, challenges only when needed.",
    "Evaluate security assumptions: honest-party liveness, bonds, watcher incentives, and timeouts.",
    "Test the worst-case path: dispute flow, exit-to-L1 reliability, and maximum exit time.",
    "Prefer audited code, real adversarial tests, and clear monitoring endpoints before scaling."

          "Use audited libraries and staged releases; treat dispute code as the most sensitive surface",

        "then": [
          "Check whether a unilateral exit-to-L1 is documented and realistically usable",
          "Prefer systems with public bonds, transparent watcher incentives, and proven challenges",

        "then": [
          "Read the documented maximum dispute duration and how fee spikes are handled",
          "Avoid edge-case timing; act promptly inside challenge windows",

  },
  "riskNotes": [
    "BitVM-style security depends on at least one honest, responsive challenger during timeouts.",
    "Disputes can add latency and consume blockspace; UX must surface timers and exit paths clearly.",
    "Encoding computation into commitments and challenge paths is complex—audits and reference tooling matter.",
    "Watcher incentives must be sustainable; operator-only watching is a structural weakness."
