How this article reaches the blockchain

It was combined with the other 12 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
0x92c298014b5f4c91387dadb6cb3342c39d7dac65fdaab25f90f94721e997e356

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
    0xe0afffcb3c9847b1769d6de7c17ecc19ed508ac2ce5007199254ee3b4d89c570

  2. Step 2, combined with the value before it
    0x83526fdd60fb386f3e46a35273035bba1b2c4a340a081a8061d99605d955885b

    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":"Drkrittanawong","position":1,"role":"solo","weight":1.0000}],"body":{"content":[{"content":[{"text":"The tragic death of 24-year-old after the NYC Marathon is a reminder that even y…

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-GJDLNQT3/canonical" | shasum -a 256

    Should print 844e7a6aca36f3bc6c2cf7be653c84e86f1cd7771216e4c8c7da97bc69d4c61e

  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-GJDLNQT3 CONTENT=844e7a6aca36f3bc6c2cf7be653c84e86f1cd7771216e4c8c7da97bc69d4c61e DIGEST=$(printf '%s' "$STAMP" | shasum -a 256 | cut -d' ' -f1) printf '00%s%s' "$DIGEST" "$CONTENT" | xxd -r -p | shasum -a 256

    Should print 92c298014b5f4c91387dadb6cb3342c39d7dac65fdaab25f90f94721e997e356

  3. 3. Combine step 1

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

    printf '01%s%s' "e0afffcb3c9847b1769d6de7c17ecc19ed508ac2ce5007199254ee3b4d89c570" "92c298014b5f4c91387dadb6cb3342c39d7dac65fdaab25f90f94721e997e356" | xxd -r -p | shasum -a 256

    Should print a28d5cbdc787de1f0d1b9090522142498d3e920f410e5d216e155672477cf96c

  4. 4. Combine step 2

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

    printf '01%s%s' "83526fdd60fb386f3e46a35273035bba1b2c4a340a081a8061d99605d955885b" "a28d5cbdc787de1f0d1b9090522142498d3e920f410e5d216e155672477cf96c" | xxd -r -p | shasum -a 256

    Should print d9643581389215417ac8cd5756b0ce4cb0668525c377b0e313363c233209f1ba

  5. 5. 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.
