Snapshot Policy (Pre-Announcement)

Rule

  • The snapshot block is the first Bitcoin block whose median-time-past (MTP) is ≥ 2025-09-03 16:00:00 UTC.
  • Finalization buffer: wait 144 additional Bitcoin blocks after the snapshot block before publishing the official height.

Fairness

  • Pre-announce the timestamp at least 1–2 weeks in advance.
  • No blacklists/whitelists; include all addresses per Bitcoin consensus.
  • Claim window: 15 months from the official snapshot publication; after this, unclaimed allocations follow the Unclaimed policy below.

Contingency

  • If Bitcoin experiences a ≥6-block reorg overlapping the snapshot window, shift to the next block with MTP ≥ and reapply the 144-block buffer.

Deliverables

  • Publish: exact height H, Merkle roots, and reproducible scripts to recompute balances.
  • Provide: claim portal/CLI and domain-separated signing standard per claim_spec_v1.md.

Unclaimed policy

  • After the 15-month claim window, any unclaimed allocations are routed to a vesting contract with beneficiary set to the disclosed founder address (address-only disclosure). Vesting is enforced on-chain with a 12-month cliff and linear monthly unlocks over 48 months.
