How this article reaches the blockchain

It was combined with the other 7 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
0x5b09fb4d327ff20a40b5e1e0c041618e6fb2dec4a21417fe50dba91e69435773

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 after it
    0xc00f07c55601b386b6452ec1f3eb7c38043c36ec8b9794771eaf5369b542fa88

  2. Step 2, combined with the value before it
    0x306aefb4b1e85999b895fbed12702569baddc2d243d0517a3ec3643bc37b3707

  3. Step 3, 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.

Worked out from this article

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,"authors":[{"identity":"financeguy","position":1,"role":"solo","weight":1.0000}],"body":{"content":[{"content":[{"text":"🚨 BTC just ripped from ~$65K to $75K in a day. What's actually happening:","type":"text"}],"type":"par…

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-2026-0821-PY4HNHEI/canonical" | shasum -a 256

    Should print 35b916042bb6a1d049ccb54075754bab06fce11bc7208d66acc157683a1caa8b

  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-2026-0821-PY4HNHEI CONTENT=35b916042bb6a1d049ccb54075754bab06fce11bc7208d66acc157683a1caa8b DIGEST=$(printf '%s' "$STAMP" | shasum -a 256 | cut -d' ' -f1) printf '00%s%s' "$DIGEST" "$CONTENT" | xxd -r -p | shasum -a 256

    Should print 5b09fb4d327ff20a40b5e1e0c041618e6fb2dec4a21417fe50dba91e69435773

  3. 3. Combine step 1

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

    printf '01%s%s' "5b09fb4d327ff20a40b5e1e0c041618e6fb2dec4a21417fe50dba91e69435773" "c00f07c55601b386b6452ec1f3eb7c38043c36ec8b9794771eaf5369b542fa88" | xxd -r -p | shasum -a 256

    Should print e2b88e380829b1c0e199b35157c5473d1bdeb8707721c426367b03afce75a774

  4. 4. Combine step 2

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

    printf '01%s%s' "306aefb4b1e85999b895fbed12702569baddc2d243d0517a3ec3643bc37b3707" "e2b88e380829b1c0e199b35157c5473d1bdeb8707721c426367b03afce75a774" | xxd -r -p | shasum -a 256

    Should print 0ba283e3f17a592f6b90c7c2034b2bc7a6907613565a2401a1d2c9390b376157

  5. 5. Combine step 3

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

    printf '01%s%s' "d6410d5e51f51788bd42ba793c9866dc9b4168ad507e32e53cb04274cfde22ef" "0ba283e3f17a592f6b90c7c2034b2bc7a6907613565a2401a1d2c9390b376157" | xxd -r -p | shasum -a 256

    Should print c24aec2745b7de4fa00ca459520e6e767a593720e8654115153e290b2967b1e5

  6. 6. 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.
