Public Key
Definition
A cryptographic identifier that can be shared publicly to receive assets or verify signatures.
In Plain English
A public key is like a mailing address: people can send things to it, but it does not let them open your mailbox.
Real-World Example
A company may publish a wallet address so customers can send blockchain payments.
Why It Matters for Your Work
Public keys and addresses make blockchain transactions possible, but sending to the wrong address may be irreversible.
Common Mistake
Confusing public keys with private keys. Public can be shared; private must be protected.
