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
0xdea901c0cea2737152a36e5ac41df4e891f9d9d3855fe0a60329866d9b33e0a7

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

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":"Soy Milk!!","type":"text"}],"type":"paragraph"}],"type":"doc"},"disclosures":null,"key…

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-2026-1111-UG5CCZIP/canonical" | shasum -a 256

    Should print 5bb8a8c5849e6576b8e2627db15cb4d376c1eacaeca1b884dffe29d73d1c0da5

  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-2026-1111-UG5CCZIP CONTENT=5bb8a8c5849e6576b8e2627db15cb4d376c1eacaeca1b884dffe29d73d1c0da5 DIGEST=$(printf '%s' "$STAMP" | shasum -a 256 | cut -d' ' -f1) printf '00%s%s' "$DIGEST" "$CONTENT" | xxd -r -p | shasum -a 256

    Should print dea901c0cea2737152a36e5ac41df4e891f9d9d3855fe0a60329866d9b33e0a7

  3. 3. Combine step 1

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

    printf '01%s%s' "c393ff2fd9df532e1c7231df60f466c30eccacfda2e34f1575579107fe1c7a5d" "dea901c0cea2737152a36e5ac41df4e891f9d9d3855fe0a60329866d9b33e0a7" | xxd -r -p | shasum -a 256

    Should print de624425f74f87c88ffb7258df96774598da9a9e26a4b4602e8fff93f9f2a908

  4. 4. Combine step 2

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

    printf '01%s%s' "de624425f74f87c88ffb7258df96774598da9a9e26a4b4602e8fff93f9f2a908" "96f90c586827a0d2afca3b25b3f40d11e23707ce2e08f1ab3e2d8920241350e7" | xxd -r -p | shasum -a 256

    Should print 1672442efede6984a0ae8d802dfa83b2783295b54dea76973154590f1cbc0d18

  5. 5. Combine step 3

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

    printf '01%s%s' "c9e184e5d9d1b347f46433983f46b9e06271fee911245c912d21da0da05ef609" "1672442efede6984a0ae8d802dfa83b2783295b54dea76973154590f1cbc0d18" | xxd -r -p | shasum -a 256

    Should print c5de4ed408e416d7a81b8b4dd7000cca42760dc99871d9dc13715f36f8b0cf2f

  6. 6. Combine step 4

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

    printf '01%s%s' "da3c1e21a060ff4b04daac50eff2f35dc1e9a4d7abd1ab04390e3c753c37169d" "c5de4ed408e416d7a81b8b4dd7000cca42760dc99871d9dc13715f36f8b0cf2f" | xxd -r -p | shasum -a 256

    Should print 35ded4f6e28244e45970a3984b9900865960b4129277e98b1165cec8d30d7ea6

  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.
