How this article reaches the blockchain

It was combined with the other 15 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
0x6418044e82e03139e38fbac1aab847af85a8d0b45507e4e1df7e781b6f08d744

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
    0xa65147af4833c1f7dbfa13f28218732ba760527fc8f847e5303b96885d3c9f21

    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":"simple_recipes_daily","position":1,"role":"solo","weight":1.0000}],"body":{"content":[{"content":[{"text":"Ingredients","type":"text"}],"type":"paragraph"},{"content":[{"content":[{…

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-2026-0927-BUZISTU6/canonical" | shasum -a 256

    Should print 5772f086da2e6bbd65132e93d168972e4eecc62adc6f0af31523aabd690ab6c3

  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-2026-0927-BUZISTU6 CONTENT=5772f086da2e6bbd65132e93d168972e4eecc62adc6f0af31523aabd690ab6c3 DIGEST=$(printf '%s' "$STAMP" | shasum -a 256 | cut -d' ' -f1) printf '00%s%s' "$DIGEST" "$CONTENT" | xxd -r -p | shasum -a 256

    Should print 6418044e82e03139e38fbac1aab847af85a8d0b45507e4e1df7e781b6f08d744

  3. 3. Combine step 1

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

    printf '01%s%s' "a65147af4833c1f7dbfa13f28218732ba760527fc8f847e5303b96885d3c9f21" "6418044e82e03139e38fbac1aab847af85a8d0b45507e4e1df7e781b6f08d744" | xxd -r -p | shasum -a 256

    Should print ce6c8d52ea4eeb48fdfa8d80ba623ac7cf34e27d5506308aeabda989059c640f

  4. 4. Combine step 2

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

    printf '01%s%s' "cf8e8b8cf21ef16139446ff6377193b0985a3337af036dde433d87f7918121ec" "ce6c8d52ea4eeb48fdfa8d80ba623ac7cf34e27d5506308aeabda989059c640f" | xxd -r -p | shasum -a 256

    Should print 7fe40eea1bad2bdb93609aa8e573a82f09091eb8006a6e0767682226d1a75fe1

  5. 5. Combine step 3

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

    printf '01%s%s' "7fe40eea1bad2bdb93609aa8e573a82f09091eb8006a6e0767682226d1a75fe1" "aa578ddfcefd3ad1326c523a92417afa15727ca3825ec5b50289ac1d7e795dc3" | xxd -r -p | shasum -a 256

    Should print 6eaca6f8fad3941a58480910f7552e56ce37d770b0737e6b02e39bbbe2017c73

  6. 6. Combine step 4

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

    printf '01%s%s' "6eaca6f8fad3941a58480910f7552e56ce37d770b0737e6b02e39bbbe2017c73" "189f16615f033de7dd9a4b992b1aef6470f63541e5680e16fcbbeed9fdc2af1e" | xxd -r -p | shasum -a 256

    Should print 01089cc494102438cf94dcf8e1f212fa7cd9533e8e954ccc633bfbcec4587c94

  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.
