How this article reaches the blockchain

It was combined with the other 9 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
0xbeaece1fdd99e17e6d7c1bc987197704fcd32f5024e1043a08950d91c0482b8c

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 after it

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,"authors":[{"identity":"cardiovitahash","position":1,"role":"solo","weight":1.0000}],"body":{"content":[{"content":[{"marks":[{"type":"bold"}],"text":"AI adoption in healthcare is accelerating but trust remains the key barr…

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-2026-0826-LL356GHD/canonical" | shasum -a 256

    Should print ac0302aa7d4912bb41ee78bcd73ba40ac376ab7c933fadc2c2d557fe27d665a4

  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-2026-0826-LL356GHD CONTENT=ac0302aa7d4912bb41ee78bcd73ba40ac376ab7c933fadc2c2d557fe27d665a4 DIGEST=$(printf '%s' "$STAMP" | shasum -a 256 | cut -d' ' -f1) printf '00%s%s' "$DIGEST" "$CONTENT" | xxd -r -p | shasum -a 256

    Should print beaece1fdd99e17e6d7c1bc987197704fcd32f5024e1043a08950d91c0482b8c

  3. 3. Combine step 1

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

    printf '01%s%s' "beaece1fdd99e17e6d7c1bc987197704fcd32f5024e1043a08950d91c0482b8c" "de72e41e8df4029aac473dbd0ba5a51b0aca8b4f27cd71fc67eda197f9d146b6" | xxd -r -p | shasum -a 256

    Should print 76dde7cd482f236a0e6c83be6173705bd5114a5222b225bd32a05a19318416a2

  4. 4. Combine step 2

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

    printf '01%s%s' "76dde7cd482f236a0e6c83be6173705bd5114a5222b225bd32a05a19318416a2" "c112e8612717a7f052b7a4aa8ba4c3650dd800dd421a822ad81d582a1f172412" | xxd -r -p | shasum -a 256

    Should print 5f8fd93d1342e6f582a2588d1c24ba86122827e4293e14743a5edbfb0c06c744

  5. 5. Combine step 3

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

    printf '01%s%s' "6a9201a5fa622d9e3cfbfb0a4ba6051fc37c1c172f63aa6087bfb245df8b1320" "5f8fd93d1342e6f582a2588d1c24ba86122827e4293e14743a5edbfb0c06c744" | xxd -r -p | shasum -a 256

    Should print a21c8ba55f0fc6e57b545c6de25652a6b6edb54b52b930f491c0ed5edde1df08

  6. 6. Combine step 4

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

    printf '01%s%s' "a21c8ba55f0fc6e57b545c6de25652a6b6edb54b52b930f491c0ed5edde1df08" "8680bcd982597baa59b5474438998fb2c932f4e7c4dc44c0962bfa4b522c7829" | xxd -r -p | shasum -a 256

    Should print d18600dbfb6bcb059d5c725341c007e642eceb0a8393d6b788c0fb7609a936ac

  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.
