GKNOT Wallet
The world’s first finger vein-based cryptocurrency wallet
A biometric security wallet with ETUNNEL’s unique technology,
created and transmitted using finger vein recognition
It is the world’s first biometric authentication wallet,
applying finger vein authentication throughout the entire process, from wallet creation to transactions.
Finger veins are unique to each person and cannot be replicated, offering superior security and convenience compared to traditional password or fingerprint-based wallets.
WHY
It’s time to change
the way you
authenticate.
$200 million worth of Bitcoin,
“frozen” after forgetting the password
A foreign investor bought a large amount of Bitcoin in early 2013 and stored it in a hardware wallet.
However, after losing the mnemonic (12-word recovery key) for wallet recovery,
the investor was no longer able to access worth approximately $200 million.
The hardware wallet, having exhausted all 10 password entry attempts,
entered an automatic lock state. The user was quoted in an interview saying,
“Staring at the laptop is torture,” and expressed living the rest of their life in regret and despair.
Forgot the location where the paper
wallet was hidden, and it was “permanently
deleted” during a home renovation
A blogger in South Korea thought they had written the mnemonic on paper and hidden it in a secret space behind a bookshelf. However, during an interior renovation a few years later,
the space was demolished, and they completely lost access to the wallet without any means of recovery.
The wallet contained Ethereum worth approximately $7,200, and the blogger shared their story
on their blog, saying, “Even now, just thinking about that space makes my heart sink,”
which resonated with readers and caused shock and sympathy.
