user7: I have an question about the asset fingerprint.
For example here:
https://pool.pm/333427e94971f530653bb945f34f914252ad570c0b84dfd8c8e8c97b.ExtraHate067
it shows asset1yjj6l5ude4gf274ya0exk4vymaaj0464yxmnvm
here it shows the same: https://cardano-tools.io/latest?q=ExtraHate067
but the explorer
https://explorer.cardano.org/en/transaction?id=0d560535733237eaafa4f3c25e648d147dc93a048e3dc66e5199cd86986b5a2c
shows asset1q7c0qhulpty4tcdp3cwt8eg5edws9c8lqyldlr did they change the hash algorithm?

user801: Wow, good catch. You can see fingerPrint function here. It's located in cardano-graphql project.
export const assetFingerprint = (asset: Pick<Asset, 'assetName' | 'policyId'>) =>
  new AssetFingerprint(
    Buffer.from(asset.policyId, 'hex'),
    asset.assetName !== '' ? Buffer.from(asset.assetName, 'hex') : undefined)
    .fingerprint()

After running this code
const fingerPrint = ({ policyId, assetName }) => {
  const af = new AssetFingerprint(
    Buffer.from(policyId, 'hex'),
    Buffer.from(assetName, 'hex'),
  ).fingerprint()

  return af
}

const combinations = [
  {policyId:'333427e94971f530653bb945f34f914252ad570c0b84dfd8c8e8c97b',
   assetName:'457874726148617465303637'},
  {policyId: "",
   assetName:'457874726148617465303637'},
  {policyId: '333427e94971f530653bb945f34f914252ad570c0b84dfd8c8e8c97b',
   assetName: ""},
]

combinations.map(fingerPrint)

I got
[
  'asset1yjj6l5ude4gf274ya0exk4vymaaj0464yxmnvm',
  'asset1q7c0qhulpty4tcdp3cwt8eg5edws9c8lqyldlr',
  'asset19nqnahcv54krdv8mcc0ne60wlkealw5qaztzvp'
]

Which means that policyId is missing in the explorer but the fingerprint function is the same.
You can rerun my code in replit.
I also created an issue for cardano-explorer-app.

user2125: Fixed in https://github.com/input-output-hk/cardano-graphql/pull/526. Thanks for the investigation.
Edit: Released in 5.0.0, adopted by cardano-explorer-app in 1.6.0

user88: This looks like a bug in explorer.cardano.org.
You can use the JS package @emurgo/cip14-js to check for yourself.
import AssetFingerprint from '@emurgo/cip14-js'

const assetFingerprint = new AssetFingerprint(
    Buffer.from('333427e94971f530653bb945f34f914252ad570c0b84dfd8c8e8c97b', 'hex'),
    Buffer.from('457874726148617465303637', 'hex'),
  )
assetFingerprint.fingerprint()
// returns asset1yjj6l5ude4gf274ya0exk4vymaaj0464yxmnvm
