How this article reaches the blockchain

It was combined with the other 18 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
0x67c95347c5fa7852855baa7239549c975b211b81e7ca61713bba5059d742c988

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":"moveandthriveclub","position":1,"role":"solo","weight":1.0000}],"body":{"content":[{"content":[{"text":"Need to catch up with a friend or chat with family? Instead of sitting on the…

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-2026-1009-SOYRIC4S/canonical" | shasum -a 256

    Should print c3cd5539a0673a4d5262704c76b214e88d595b4321ac4f68e204052b54c6dde9

  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-2026-1009-SOYRIC4S CONTENT=c3cd5539a0673a4d5262704c76b214e88d595b4321ac4f68e204052b54c6dde9 DIGEST=$(printf '%s' "$STAMP" | shasum -a 256 | cut -d' ' -f1) printf '00%s%s' "$DIGEST" "$CONTENT" | xxd -r -p | shasum -a 256

  3. 3. Combine step 1

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

    printf '01%s%s' "67c95347c5fa7852855baa7239549c975b211b81e7ca61713bba5059d742c988" "e0f78ccc27653407eb3c7caaf83025beb684f71477d0862787214f6b185a4f8a" | xxd -r -p | shasum -a 256

    Should print 321929a616860dacc7c147f86af99b137d3fc6308e1eade2bfaa09fbe54724df

  4. 4. Combine step 2

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

    printf '01%s%s' "321929a616860dacc7c147f86af99b137d3fc6308e1eade2bfaa09fbe54724df" "1d81d933115b939455536aa3f869e03da7aed18f901851e2dc928386d8c932ba" | xxd -r -p | shasum -a 256

  5. 5. Combine step 3

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

    printf '01%s%s' "e82bccf903e51ff8a1e4be6fef64676bc83ac2f8527ac26dd97c522b30eb20e8" "9544434adc4bff681dabbe85f0bed8127c8ebc681826cd5b6a618d47b1a3a76c" | xxd -r -p | shasum -a 256

    Should print 2e2b7a98c527abb764ea88e886dd169e6d135e7fefec2a5590ba44b68219312d

  6. 6. Combine step 4

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

    printf '01%s%s' "2ecef9dbf25e08daa8263ffbfff2a454ffa33a24827239aa072bafc40e22825d" "2e2b7a98c527abb764ea88e886dd169e6d135e7fefec2a5590ba44b68219312d" | xxd -r -p | shasum -a 256

  7. 7. Combine step 5

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

    printf '01%s%s' "fe61a3e7f1f8747a9f673767cd49f1fcaa5b415b85ddf5a046e009b0d2f4ebac" "180f27a5e63b918783e114c2441ae403faefb0077b18cf1a1eecc5aca0d0aa0f" | xxd -r -p | shasum -a 256

  8. 8. 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.
