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
0xc059add00fe2f859b0022a87ebe8769440f7291bcf7ef075aafede3f71b74872

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

    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":"moveandthriveclub","position":1,"role":"solo","weight":1.0000}],"body":{"content":[{"content":[{"text":"When you lift weights, you aren't just building muscle—you are forging a shor…

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-2026-0918-FOV53TAS/canonical" | shasum -a 256

    Should print db124577a3b78fe0ae028d564ea69d708ebbe187cfee28d282df902166bd8ac6

  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-2026-0918-FOV53TAS CONTENT=db124577a3b78fe0ae028d564ea69d708ebbe187cfee28d282df902166bd8ac6 DIGEST=$(printf '%s' "$STAMP" | shasum -a 256 | cut -d' ' -f1) printf '00%s%s' "$DIGEST" "$CONTENT" | xxd -r -p | shasum -a 256

    Should print c059add00fe2f859b0022a87ebe8769440f7291bcf7ef075aafede3f71b74872

  3. 3. Combine step 1

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

    printf '01%s%s' "ff5cb9a2748120a28965a5960ce6b7617062a2d74dcd98320424e82c7de58243" "c059add00fe2f859b0022a87ebe8769440f7291bcf7ef075aafede3f71b74872" | xxd -r -p | shasum -a 256

    Should print cf5a53f476037877f09fc96d7b06a068e08d1af369cc3dc4701d4b7426df862a

  4. 4. Combine step 2

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

    printf '01%s%s' "7b9f2ba4581211508b9b04bed428d96af821da211e796fbe37145799162e80f1" "cf5a53f476037877f09fc96d7b06a068e08d1af369cc3dc4701d4b7426df862a" | xxd -r -p | shasum -a 256

    Should print b0a7aee5bd0ae5aab080adebbc503b312924644ee2a68b83a48581878ede5d18

  5. 5. Combine step 3

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

    printf '01%s%s' "5512aa4312e44cbfe6e606916bb88ed9c0dd69d90e820e16efed750edb411931" "b0a7aee5bd0ae5aab080adebbc503b312924644ee2a68b83a48581878ede5d18" | xxd -r -p | shasum -a 256

    Should print 4129c5ad64d926f37c538109754f0e9263f89c02ced93bdd213ba4405e4e9531

  6. 6. Combine step 4

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

    printf '01%s%s' "4129c5ad64d926f37c538109754f0e9263f89c02ced93bdd213ba4405e4e9531" "515b55281df5784e98cbad465386a2275a74de0c9ea58616bb751482c219f11d" | xxd -r -p | shasum -a 256

    Should print 5c87f8e69f2c982a1152aee23624c8f3684d400af4fd78b690d8ebfd3a21ee7f

  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.
