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
0x7de0f93bcc1c76dc5a6d39ae2f2e6f3b2247b5b80a2598c257200da397a62415

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
    0x13fe60efcce9c9ba504f1a4054837a3110f6b16976bc87583e4a01fe6b746ece

    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":"glowguide_daily","position":1,"role":"solo","weight":1.0000}],"body":{"content":[{"content":[{"marks":[{"attrs":{"color":"purple"},"type":"textColor"},{"attrs":{"font":"arial"},"typ…

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-2026-1005-753TC6DQ/canonical" | shasum -a 256

    Should print 1f76503c6352324e31c5b6b9a3846d2577d3a57f94e90085e3d0305a2f3c32c6

  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-2026-1005-753TC6DQ CONTENT=1f76503c6352324e31c5b6b9a3846d2577d3a57f94e90085e3d0305a2f3c32c6 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 published value goes first, then the value you have.

    printf '01%s%s' "13fe60efcce9c9ba504f1a4054837a3110f6b16976bc87583e4a01fe6b746ece" "7de0f93bcc1c76dc5a6d39ae2f2e6f3b2247b5b80a2598c257200da397a62415" | xxd -r -p | shasum -a 256

    Should print 002ee7ef16bfc560ed584b4da7df8488a1bf4222b451e3e1c14041eed23cc101

  4. 4. Combine step 2

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

    printf '01%s%s' "c342c6e3f61642a45ac6265a2a24743c3e2ce7a426462d8fd61a10582d26bf08" "002ee7ef16bfc560ed584b4da7df8488a1bf4222b451e3e1c14041eed23cc101" | xxd -r -p | shasum -a 256

    Should print 2984af38d8e55376ecb9d6cd12b5db21fe73adb96d4d8edff5127cbeec9513d1

  5. 5. Combine step 3

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

    printf '01%s%s' "2984af38d8e55376ecb9d6cd12b5db21fe73adb96d4d8edff5127cbeec9513d1" "db370880b6954311cdd1a54ca92c8fa431829e1c1779fa227f25a99d896add5d" | xxd -r -p | shasum -a 256

    Should print a9f799966a483b5e226937bad04c452defeec34e6edcd62f9a25542551c7c5b8

  6. 6. Combine step 4

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

    printf '01%s%s' "a9f799966a483b5e226937bad04c452defeec34e6edcd62f9a25542551c7c5b8" "f6e9bee092ca40c02a96ef8ee26ca39530effb9351665feb3ba92e44033f0037" | xxd -r -p | shasum -a 256

    Should print 38256faf2512c46a9e2a74487a2b8a28fd1c0c136819a67fdf612f505b6e96b9

  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.
