How this article reaches the blockchain

It was combined with the other 12 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
0xb63c75fab5b7c75eb4b4152e79d6834ba617c63a01240435d673f6fae3893efd

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

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":"glowguide_daily","position":1,"role":"solo","weight":1.0000}],"body":{"content":[{"content":[{"text":"Have you heard of skin flooding? This popular skincare technique focuses on lay…

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-2026-1112-QIYNLEXL/canonical" | shasum -a 256

    Should print 1bcf66879e92a7689e6cf02a1ef894f237f328bfc2be3c5dbd69c35fb14db053

  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-2026-1112-QIYNLEXL CONTENT=1bcf66879e92a7689e6cf02a1ef894f237f328bfc2be3c5dbd69c35fb14db053 DIGEST=$(printf '%s' "$STAMP" | shasum -a 256 | cut -d' ' -f1) printf '00%s%s' "$DIGEST" "$CONTENT" | xxd -r -p | shasum -a 256

    Should print b63c75fab5b7c75eb4b4152e79d6834ba617c63a01240435d673f6fae3893efd

  3. 3. Combine step 1

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

    printf '01%s%s' "5d4a756122b4475512362beabbce1ad01283a3ce4d7fcfdeecbf01ad8e869da6" "b63c75fab5b7c75eb4b4152e79d6834ba617c63a01240435d673f6fae3893efd" | xxd -r -p | shasum -a 256

    Should print ec03dce44efbef93c9dc31c7d456ed8abac32ce0cc045b85e26ae3f8976643b5

  4. 4. Combine step 2

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

    printf '01%s%s' "eefcbf52a88b708e3003ac5d7a56f34dba070f82d2b01f58855e85a3f06c9c8c" "ec03dce44efbef93c9dc31c7d456ed8abac32ce0cc045b85e26ae3f8976643b5" | xxd -r -p | shasum -a 256

    Should print 9a4f9b9a0dedc86dee7f155e2d187caf30bf6587ddee5121c729b4cd7a10050d

  5. 5. Combine step 3

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

    printf '01%s%s' "8579a1fcc329bd96d865b1c1bb98e9e63f191eadf35db210047e545c2804f5a6" "9a4f9b9a0dedc86dee7f155e2d187caf30bf6587ddee5121c729b4cd7a10050d" | xxd -r -p | shasum -a 256

    Should print c686ce1ad37287ba022494162d00d61e0f5cbbe1a6acba7f779824cf91156f85

  6. 6. Combine step 4

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

    printf '01%s%s' "c686ce1ad37287ba022494162d00d61e0f5cbbe1a6acba7f779824cf91156f85" "ff35541912e2df2feec01871825d1d7f08f12c52f251394d82803cd3c7ed73aa" | xxd -r -p | shasum -a 256

    Should print 173f6fd378092e865af1d499866e40bbda58a173260dc2ae347f6889884c4c7d

  7. 7. 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.
