How this article reaches the blockchain

It was combined with the other 17 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
0xf1ae0cd5e9f0ffbd34bc80652c8edc68a7971792dc5550f55c87cfa86f6bc5fa

Built from this article's content hash and its stamp ID, as sha256(0x00 || sha256(utf8(stampId)) || contentHash).

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":"In management of cerebrovascular diseases, artificial intelligence (AI) emerges and plays a role through advancements in prediction, imaging, diagnosis, and treatment. Revolutionized AI-based tools allow us to catch a glimpse o…

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-2026-1008-OR2LMNJW/canonical" | shasum -a 256

    Should print 60f6afee83b5dcae52395206ce7ced203b7b5065feff0d635c120f810bf058c3

  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-2026-1008-OR2LMNJW CONTENT=60f6afee83b5dcae52395206ce7ced203b7b5065feff0d635c120f810bf058c3 DIGEST=$(printf '%s' "$STAMP" | shasum -a 256 | cut -d' ' -f1) printf '00%s%s' "$DIGEST" "$CONTENT" | xxd -r -p | shasum -a 256

    Should print f1ae0cd5e9f0ffbd34bc80652c8edc68a7971792dc5550f55c87cfa86f6bc5fa

  3. 3. Combine step 1

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

    printf '01%s%s' "f1ae0cd5e9f0ffbd34bc80652c8edc68a7971792dc5550f55c87cfa86f6bc5fa" "fe3c99a0e564ae6b0c20b2da63a305cfc82861b5aacedca89bbc5a6406d8e5f7" | xxd -r -p | shasum -a 256

    Should print a52da08070a61983d76fefac5053890a2a79509b8841b6fb0122ff6100fe79b4

  4. 4. Combine step 2

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

    printf '01%s%s' "b49f9cf37d82be03bb5e014b97ffc525dc506dd57cd5dab2c21db7483bdf2523" "a52da08070a61983d76fefac5053890a2a79509b8841b6fb0122ff6100fe79b4" | xxd -r -p | shasum -a 256

    Should print 64537a68fabe7c81da356e02071072c5eb75f42856857734ef290a16d289ea60

  5. 5. Combine step 3

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

    printf '01%s%s' "c73e7f2c9c616a30eb56bd6b33fac81d7cc7c805a8b34862224399fdcec319e6" "64537a68fabe7c81da356e02071072c5eb75f42856857734ef290a16d289ea60" | xxd -r -p | shasum -a 256

    Should print 366704e51be5339bcfbd2dadf5673d4c73b3d9628408711d9dedcf5b792e4aac

  6. 6. Combine step 4

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

    printf '01%s%s' "366704e51be5339bcfbd2dadf5673d4c73b3d9628408711d9dedcf5b792e4aac" "730b741698ce1e44832a12a50a945b3fa53dc581c3a8346cb6c8125d23b358a3" | xxd -r -p | shasum -a 256

    Should print c08b27e8a2d549dec72fb176403f4f93fa2e2351f43dff765d15a7ffbc41574f

  7. 7. Combine step 5

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

    printf '01%s%s' "c08b27e8a2d549dec72fb176403f4f93fa2e2351f43dff765d15a7ffbc41574f" "efe67e8818fed37489d7df9f4ccef876c449a371f6aa50ca6c7ee89876435ae8" | xxd -r -p | shasum -a 256

    Should print eb001c580d29d4587f4a3e8aafc9e961640c7ff2d9442e2f96576d645b8f22a8

  8. 8. 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.
