How this article reaches the blockchain

It was combined with the other 16 articles published that day, one step at a time, until the whole day became a single value. That one value is what Vitahash wrote to the blockchain. Change a single character of this article and the starting value below changes, so none of the steps would land on the recorded one.

Starting value for this article
0x84d06f2996b75c16b1c3c5db27e3adbaa6dab69087e72ab178d8fb7e4870e64d

Built from this article's content hash and its stamp ID, as sha256(0x00 || sha256(utf8(stampId)) || contentHash).

  1. Step 1, combined with the value before it
    0xcc726d408f6663dfb1f79c45763d310611376625219557511a10ed3811ec5e26

    This is the value for the whole day.

Value these steps arrive at

What the blockchain says

Two values, reached two different ways. The one above was worked out from this article. The one below was read back from the record on Base.

Read it yourself on EAS

They are the same value, so this article was published that day with exactly the text above.

Check it yourself

Every number on this page came from Vitahash. Copy the article's exact text below and check it against the hash above, using any SHA-256 tool.

{"abstract":null,"agreement":false,"authors":[{"identity":"Unfiltered","position":1,"role":"solo","weight":1.0000}],"body":{"content":[{"content":[{"text":"You’ve seen the evolution... From Furby to Labubu!! Now you know what comes next…","…

Copy this text, paste it into any SHA-256 tool, and compare the result with the hash shown above. If the two match, this is exactly what Vitahash recorded.

For a technical reader: the terminal route

  1. 1. Hash the article yourself

    This downloads the exact text Vitahash hashed, in the exact form it hashed it, and hashes it again on your machine. Nothing Vitahash wrote runs here.

    curl -s "https://api.vitahash.org/api/verify/STAMP-2026-0924-SPRFAYWD/canonical" | shasum -a 256

    Should print 1bef9fafb1c2883a83d07e2ffee37885ba2cf8ed80d59b09680f0f45579c6b83

  2. 2. Build this article's starting value

    The stamp ID is folded in with the hash, so one article's record can never stand in for another's.

    STAMP=STAMP-2026-0924-SPRFAYWD CONTENT=1bef9fafb1c2883a83d07e2ffee37885ba2cf8ed80d59b09680f0f45579c6b83 DIGEST=$(printf '%s' "$STAMP" | shasum -a 256 | cut -d' ' -f1) printf '00%s%s' "$DIGEST" "$CONTENT" | xxd -r -p | shasum -a 256

    Should print 84d06f2996b75c16b1c3c5db27e3adbaa6dab69087e72ab178d8fb7e4870e64d

  3. 3. Combine step 1

    The published value goes first, then the value you have.

    printf '01%s%s' "cc726d408f6663dfb1f79c45763d310611376625219557511a10ed3811ec5e26" "84d06f2996b75c16b1c3c5db27e3adbaa6dab69087e72ab178d8fb7e4870e64d" | xxd -r -p | shasum -a 256

    Should print 0aba8b378f589186a4d34d785b3ad3e11e9061ced9213874765a71427669c3ec

  4. 4. Compare with the blockchain

    The last value above is what the whole day came to. Read the record on Base and check its merkleRoot field is the same. Vitahash is not involved in this step at all.
