How this article reaches the blockchain

It was combined with the other 11 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
0x7e1cdf00431ba4be2e9bc617854df1a06c84435619356feb5bf56c6535c7a12f

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":null,"agreement":false,"authors":[{"identity":"TheTravelEdit","position":1,"role":"solo","weight":1.0000}],"body":{"content":[{"content":[{"text":"Barbados is calling! 🌴 With crystal-clear turquoise waters, beautiful beaches, co…

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-2026-1105-KSNMLYYS/canonical" | shasum -a 256

    Should print 72dcf5b12c2e1ed7b3a4fd6a7690cc4c574c62e3d389ccea1b8d12a90238ba6b

  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-2026-1105-KSNMLYYS CONTENT=72dcf5b12c2e1ed7b3a4fd6a7690cc4c574c62e3d389ccea1b8d12a90238ba6b DIGEST=$(printf '%s' "$STAMP" | shasum -a 256 | cut -d' ' -f1) printf '00%s%s' "$DIGEST" "$CONTENT" | xxd -r -p | shasum -a 256

    Should print 7e1cdf00431ba4be2e9bc617854df1a06c84435619356feb5bf56c6535c7a12f

  3. 3. Combine step 1

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

    printf '01%s%s' "a7d927b95a422a9eb559bd4c4b277587978aaf2279c361d1ffaac3468c299422" "7e1cdf00431ba4be2e9bc617854df1a06c84435619356feb5bf56c6535c7a12f" | xxd -r -p | shasum -a 256

    Should print cbd3445a0c0b6f536166cc692d527902aa0c17e4fa7b1293fe7e8abc94fecb96

  4. 4. Combine step 2

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

    printf '01%s%s' "cbd3445a0c0b6f536166cc692d527902aa0c17e4fa7b1293fe7e8abc94fecb96" "caf3ae26ad2fdd130dc83f8fd90b7028fbf9cd00cae4742eeabdf296dcb2562f" | xxd -r -p | shasum -a 256

    Should print 0cf6688e1cdc08cbcaa58a4fd695e64c1564ae7fac0b7082d3f93984d4cbdc7b

  5. 5. Combine step 3

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

    printf '01%s%s' "e156cfe28a9842521746b77acf0f16111e12e343f22b6d877577f6f6d01639e0" "0cf6688e1cdc08cbcaa58a4fd695e64c1564ae7fac0b7082d3f93984d4cbdc7b" | xxd -r -p | shasum -a 256

    Should print 44df682a6023b81e87ff829ccca3e146cb12d98ec2a65d04100ea772c6deb9ef

  6. 6. Combine step 4

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

    printf '01%s%s' "44df682a6023b81e87ff829ccca3e146cb12d98ec2a65d04100ea772c6deb9ef" "f119904624d5c3eec5a49f2357ad6ebe30995fe5bb8735024047c82ce6f4b376" | xxd -r -p | shasum -a 256

    Should print efb0a2841ae86a42f2cad5934d41fc3fe4e5eb0afa96bca6b150b3ea749097db

  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.
