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
0x9fba4bf2652939e61c352d8f3d7430d56dc69924266e70db73c947a2d105e50a

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

    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":"mayahale","position":1,"role":"solo","weight":1.0000}],"body":{"content":[{"content":[{"text":"Aww, such sweet childhood memories! šŸ’•šŸ°","type":"text"}],"type":"paragraph"}],"type":"dā€¦

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-2026-1109-BKL3AED5/canonical" | shasum -a 256

    Should print a8868108d60a05f1f12b34c26dcf3edf4c0ac1c7454d5d6f8c114b47f81dab71

  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-2026-1109-BKL3AED5 CONTENT=a8868108d60a05f1f12b34c26dcf3edf4c0ac1c7454d5d6f8c114b47f81dab71 DIGEST=$(printf '%s' "$STAMP" | shasum -a 256 | cut -d' ' -f1) printf '00%s%s' "$DIGEST" "$CONTENT" | xxd -r -p | shasum -a 256

    Should print 9fba4bf2652939e61c352d8f3d7430d56dc69924266e70db73c947a2d105e50a

  3. 3. Combine step 1

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

    printf '01%s%s' "2b1648fba52713fe6c91cc81b0b5565291fb86def79cdaef0da9603a843ebde1" "9fba4bf2652939e61c352d8f3d7430d56dc69924266e70db73c947a2d105e50a" | xxd -r -p | shasum -a 256

    Should print 5faf82916cd3880be15e48ed2ae808797437d50ae40623d9c739e482a3be8969

  4. 4. Combine step 2

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

    printf '01%s%s' "5faf82916cd3880be15e48ed2ae808797437d50ae40623d9c739e482a3be8969" "c44d91285afa1b647ee4319ab34c3c0595b13ea04027dd96c32102b34819d279" | xxd -r -p | shasum -a 256

    Should print b8c26df3d7b683d96a49bbe0af969b9e1e10031344d6320b33b8604fda53571c

  5. 5. Combine step 3

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

    printf '01%s%s' "6bc06dc72f5dc6d837df8cbcc2c35176ccce2cb8cbb648535c1f024ba8451202" "b8c26df3d7b683d96a49bbe0af969b9e1e10031344d6320b33b8604fda53571c" | xxd -r -p | shasum -a 256

    Should print 48bb8d36bc9e4989e1abd7db5b8019afde13c7ba60804c888de69b70b630cfd7

  6. 6. Combine step 4

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

    printf '01%s%s' "1af48d2f24d3b4525281700797451b50c58cc07806552eb1cc2e7d2dd141b158" "48bb8d36bc9e4989e1abd7db5b8019afde13c7ba60804c888de69b70b630cfd7" | xxd -r -p | shasum -a 256

    Should print 633ebd26ef3198219cdb8a14837c36de2d43289e37d57c1b0e4544bfc4cc76dd

  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.
