How this article reaches the blockchain

It was combined with the other 19 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
0x1cfe6de497cd9f884ba94484a09832a1fe4b5666a18e02d3d1b763c07f90493e

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":"mayahale","position":1,"role":"solo","weight":1.0000}],"body":{"content":[{"content":[{"text":"What can you actually do with Muse?","type":"text"}],"type":"paragraph"},{"content":[{…

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-2026-0925-HTKCVV6G/canonical" | shasum -a 256

    Should print c196fd2ae7ed58b9364fb56a900989e07565321c317fa4864d38090634dcf59d

  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-2026-0925-HTKCVV6G CONTENT=c196fd2ae7ed58b9364fb56a900989e07565321c317fa4864d38090634dcf59d DIGEST=$(printf '%s' "$STAMP" | shasum -a 256 | cut -d' ' -f1) printf '00%s%s' "$DIGEST" "$CONTENT" | xxd -r -p | shasum -a 256

    Should print 1cfe6de497cd9f884ba94484a09832a1fe4b5666a18e02d3d1b763c07f90493e

  3. 3. Combine step 1

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

    printf '01%s%s' "4e2a309a049670e6729e1c32c12fd051f4b558269d3a18f9685334911ef36c3b" "1cfe6de497cd9f884ba94484a09832a1fe4b5666a18e02d3d1b763c07f90493e" | xxd -r -p | shasum -a 256

    Should print 79386d44ad3efbf8bc07c8616d233c050359dc8a0eef738182adc8dd6810539a

  4. 4. Combine step 2

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

    printf '01%s%s' "9d6fb35e8e58207102e3ed020fca09d20c145529f114e1d058ed956c08f5017b" "79386d44ad3efbf8bc07c8616d233c050359dc8a0eef738182adc8dd6810539a" | xxd -r -p | shasum -a 256

    Should print 1c5adf9f24c1361259bd3f75f752da821657b46f72772b585ff2cbfc77870e91

  5. 5. Combine step 3

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

    printf '01%s%s' "1c5adf9f24c1361259bd3f75f752da821657b46f72772b585ff2cbfc77870e91" "8c5e0bcdad701cf810b7c1d35001164268482c86a64c1e579bccb96aafd48ee4" | xxd -r -p | shasum -a 256

    Should print eef2fc0c052d8690543265b12fc46b2f16349bfff03b4fc8e4347b463c876bba

  6. 6. Combine step 4

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

    printf '01%s%s' "97c1335bc96ed40e4db026f00b899cdeec1bc932550d0e2bfbb6dc3f3ccb2bfb" "eef2fc0c052d8690543265b12fc46b2f16349bfff03b4fc8e4347b463c876bba" | xxd -r -p | shasum -a 256

    Should print c1d5d231b268f46906a4da83c556378223bf6096ded3827d3cd87ed49e6fd45c

  7. 7. Combine step 5

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

    printf '01%s%s' "c1d5d231b268f46906a4da83c556378223bf6096ded3827d3cd87ed49e6fd45c" "338087d57076385362f8b946b1aeb173dce23ad0a0d0e2a793f84da82df6b81f" | xxd -r -p | shasum -a 256

    Should print 8b2476a9102c6f8fddeaea8b440d390005d5d4f4ebd31a5e0f185dd330f209ab

  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.
