How this article reaches the blockchain

It was combined with the other 16 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
0x02e73a9e44b86654d4474e46746d302a82a31e232749396f906b3fcdf48501f0

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":null,"agreement":false,"authors":[{"identity":"simple_recipes_daily","position":1,"role":"solo","weight":1.0000}],"body":{"content":[{"attrs":{"alt":"Grandma's roasted potatoes and eggs","src":"https://media.vitahash.org/article…

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-2026-0924-347MEM44/canonical" | shasum -a 256

    Should print 400a5902a5834faa5e90b95897acf84fae6c8f4eb1f74978f9ec308a4afcb16e

  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-2026-0924-347MEM44 CONTENT=400a5902a5834faa5e90b95897acf84fae6c8f4eb1f74978f9ec308a4afcb16e 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 value you have goes first, then the published value.

    printf '01%s%s' "02e73a9e44b86654d4474e46746d302a82a31e232749396f906b3fcdf48501f0" "d21ac8f1ea66dfc32c3ec307d0e7f59f6f925b9bbda259f5d71a5680d9ba8eb5" | xxd -r -p | shasum -a 256

    Should print 0e07876838056510f078754761c3f40914a93e2e68b6d902bdc515a50f064a48

  4. 4. Combine step 2

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

    printf '01%s%s' "38fd72cec5758f158a122d0559684bdaf0c04219b07b442b0446ddf067ef6314" "0e07876838056510f078754761c3f40914a93e2e68b6d902bdc515a50f064a48" | xxd -r -p | shasum -a 256

  5. 5. Combine step 3

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

    printf '01%s%s' "8f3520ead27ea983ec9f1c1dbb7230d7d3b5cfce0b5e0418e96cdb19e25d519d" "33f6777026ff7882413ac506d5f631b15881c5c97af38b1bb507519f8ad7059a" | xxd -r -p | shasum -a 256

  6. 6. Combine step 4

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

    printf '01%s%s' "d47dc08efa7c65786867e25bd7b1a281946c5e4c2e0db41d294b70ed54087b1a" "9ee9c64e7435f69ae55ab7a13dc0a63ccfd6caba07976db685b158372e31f3bb" | xxd -r -p | shasum -a 256

  7. 7. Combine step 5

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

    printf '01%s%s' "23a9bc19d01e921126f88b0bec33529da7fd454b2f693c9f4d3d6492e5dc163b" "33c71efd9544bcb45a34807054911137e217cec8f6485b60035b69b93011a650" | xxd -r -p | shasum -a 256

  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.
