How this article reaches the blockchain

It was combined with the other 14 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
0x2f201bff739f8af79640b88ccea58f8693e78afa746fcfbaf9c6bd23cadefe4c

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

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":"Traditionally, gastrointestinal (GI) and metabolic disease have been considered separate clinical entities with the GI tract viewed primarily as a conduit for digestion and nutrient absorption, while the metabolic regulation wa…

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-2026-1106-FFLQ47K7/canonical" | shasum -a 256

    Should print 927fada440f8789e3558cc2cfceabf5e46eb9d8cd60faa4d496906e36ae801f7

  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-2026-1106-FFLQ47K7 CONTENT=927fada440f8789e3558cc2cfceabf5e46eb9d8cd60faa4d496906e36ae801f7 DIGEST=$(printf '%s' "$STAMP" | shasum -a 256 | cut -d' ' -f1) printf '00%s%s' "$DIGEST" "$CONTENT" | xxd -r -p | shasum -a 256

    Should print 2f201bff739f8af79640b88ccea58f8693e78afa746fcfbaf9c6bd23cadefe4c

  3. 3. Combine step 1

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

    printf '01%s%s' "36d284934aee24a6c90406b5d43b2cb85e7ed77a01e414b4bbe38b234f906350" "2f201bff739f8af79640b88ccea58f8693e78afa746fcfbaf9c6bd23cadefe4c" | xxd -r -p | shasum -a 256

    Should print 8592e803d59f457295504f2c8c572b9f4bee8621f89eb209aa75e701288a6fad

  4. 4. Combine step 2

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

    printf '01%s%s' "8592e803d59f457295504f2c8c572b9f4bee8621f89eb209aa75e701288a6fad" "da8fc2402fd61a8ba00be6ff22cdca41b9c3906c15e7bff7f7e70ec27d467ade" | xxd -r -p | shasum -a 256

    Should print 40d6abd9880e85daf66fb10db9f264cd25bc42786f13e6c09e177a86e9d1ce55

  5. 5. Combine step 3

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

    printf '01%s%s' "5f4c78878c433a20977edba36ce661e2bfc4a13b082d50cb735666d4d977c052" "40d6abd9880e85daf66fb10db9f264cd25bc42786f13e6c09e177a86e9d1ce55" | xxd -r -p | shasum -a 256

    Should print 5d636f88f0b1927ea271d4422d94dd394c2b112107a20025f4b5399f89482ee5

  6. 6. Combine step 4

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

    printf '01%s%s' "5d636f88f0b1927ea271d4422d94dd394c2b112107a20025f4b5399f89482ee5" "3a1f5efbf571f237939e6f56cf06693a664dfee09c4563ab88af10d1650a51ae" | xxd -r -p | shasum -a 256

    Should print 48f47fdbe0ece678c7d5078af9cd7e1430e1b809937216598ff09da61fbe69df

  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.
