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.
