Verify the drawCheck the seed against its hash yourself, in 3 steps.
Step 1: Copy the seed
e030c3aaebf0e12f87e2d4f4df1932f06cfefee41e19a7753679bfabaa9b7d69Step 2: Run SHA-256 on it as plain text
Hash all 64 characters exactly as shown. Do not use hex or bytes mode: that gives a different result. This command has the seed filled in already:
Windows (Git Bash) or Linux
echo -n e030c3aaebf0e12f87e2d4f4df1932f06cfefee41e19a7753679bfabaa9b7d69 | sha256sumMac
echo -n e030c3aaebf0e12f87e2d4f4df1932f06cfefee41e19a7753679bfabaa9b7d69 | shasum -a 256Ignore the dash at the end of the output. Any online SHA-256 tool works too, if its input is set to text.
Step 3: Compare
Your result must equal the committed hash exactly, every character.

How it works
Every draw starts from a secret random seed. The site also saves the seed's SHA-256 fingerprint, called the hash. The seed and the hash are meant to look different. You can't work back from the hash to the seed, but anyone can turn the seed into the hash, and any change to the seed gives a completely different hash.
At the draw the seed is revealed, and the winners come from it. The same seed and the same entrants always give the same winners.
What the check proves
It proves that this seed is the one the hash was made from. No one can find a different seed that gives this hash.
It does not prove when the seed was picked. This page shows the hash together with the seed, after the draw.
It does not prove who the seed picked. That also needs the full weighted list of entrants, which isn't public.
Technical detail: how a winner is picked
Winner N (counting from 0) is picked from the pool as it stood at that pull: every entrant with at least one verified entry, minus blocked accounts and anyone already drawn, sorted by entrant ID in plain character order. Each entrant's weight is their verified entry count.
Compute HMAC-SHA256 with the seed (as text) as the key and draw-N as the message. Read the first 8 bytes as a big-endian unsigned number and divide by 2^64 to get a fraction from 0 to 1. Multiply it by the total weight. Walk the sorted pool adding up weights: the winner is the first entrant whose running total goes above that number.
