How This Result Was Produced

7 steps, each one checkable against the values published below. Nothing here depends on trusting us — every input is shown.

Verify commitment was published before the draw

This sha256 hash was published when the competition was created. It proves the draw_secret could not have been changed after tickets were sold.

Verify the pool-freeze commitment was published before the beacon round

sha256 of the exact UTF-8 string 'legion-draw-v1:pool_freeze:' + pool_hash + ':' + drand_chain_hash + ':' + str(round_number) — colon-separated, no spaces, no trailing newline. Published before the targeted round resolved, it pins both the entry pool and the round while the round's randomness was still unknowable. Rebuild it from this page's published values with the command below.

Verify draw_secret matches commitment_hash

The draw_secret is revealed below. sha256(draw_secret) is shown — it must equal the commitment_hash in step 1.

Verify the drand beacon randomness

Round 32434025 of the public drand randomness beacon (chain 52db9ba70e0cc0f6eaf7803dd07447a1f5477735fd3f661792ba94600c84e971). This value is published independently by multiple operators and could not have been known when the pool above was frozen. Check it yourself: fetch https://api.drand.sh/52db9ba70e0cc0f6eaf7803dd07447a1f5477735fd3f661792ba94600c84e971/public/32434025, hex-decode the response's 'signature' field into raw bytes, then compute sha256 of those bytes — it must match the value shown here. (Hashing the ASCII hex text of the signature instead of the decoded bytes gives a different, wrong answer.) The command below does exactly that.

792bd6fd1072a0728607bb17badc703c374eb02d2671977393ebcf943bb40330

python3 -c "import hashlib, json, urllib.request; r = json.load(urllib.request.urlopen('https://api.drand.sh/52db9ba70e0cc0f6eaf7803dd07447a1f5477735fd3f661792ba94600c84e971/public/32434025')); print(hashlib.sha256(bytes.fromhex(r['signature'])).hexdigest())"

Verify the beacon's BLS signature

Before accepting the randomness above, the platform checked drand's BLS12-381 signature for this round against this chain public key — a relay can withhold a round but cannot forge one without drand's private key. Fetch the round's 'signature' field from the URL above and verify e(H(round_bytes), public_key) == e(signature, G2_generator) yourself with any BLS12-381 library; source: https://drand.love/developer/http-api/.

Reproduce the winner selection (rejection sampling)

Starting at counter=0, compute sha256(f'legion-draw-v1:draw:{draw_secret}:{pool_hash}:{drand_randomness}:{counter}') as a 256-bit integer. Let limit be the largest multiple of N below 2^256. If the value is >= limit, increment counter and retry. Otherwise winner_index = value mod N.

counter=0, winner_index=73

Check It Yourself

Run every check in your own browser. It recomputes the hashes and the winner selection locally from the values published on this page, and fetches the drand round directly from the public relays — nothing is sent to our servers, so a pass cannot depend on trusting us.

Confirm sha256(draw_secret) equals the commitment hash in step 1.
Confirm the sha256 of the entry pool below equals the pool hash in step 3. Hash the text exactly as shown — ticket numbers in ascending numeric order, separated by commas, with no spaces and no trailing newline.

Run the pre-filled command below to reproduce the beacon-seeded rejection-sampling winner index (counter=?, expected winner_index=73). This folds in the drand beacon randomness from the step above alongside the draw secret and pool hash, so the winner could not have been known until that round resolved.

Independent Timestamp Proof

Each commitment hash is anchored to the Bitcoin blockchain via OpenTimestamps. A confirmed proof establishes the hash existed before the Bitcoin block that attests it — checkable without trusting our records. Save the commitment hash to a file and check the proof with the free ots tool: printf '%s' 'COMMITMENT_HASH' > commitment.txt && ots verify -f commitment.txt proof.ots

Pool freeze commitment — anchored in Bitcoin 22 Sep 2026 22:04 UTC

What this proof does and does not show: Bitcoin confirmation takes hours, while the targeted drand round resolves seconds after the pool freeze — so a confirmed proof here demonstrates the pool-freeze commitment existed before its attesting block, not that the freeze happened before the drand round. The freeze-before-round ordering rests on the commitment having been published before the round resolved (step 2 above) and on our audit records.
