A public key is a cryptographic code used in blockchain and cryptocurrency systems to receive funds and verify digital signatures. It is paired with a private key, which must remain secret to authorize transactions. Public keys can be safely shared with others, as they allow anyone to send cryptocurrency to the associated address without compromising security. They are generated using cryptographic algorithms and form the foundation of asymmetric encryption.
Coinbase has formed an independent advisory board of cryptography and quantum experts to evaluate long-term risks that quantum computing could pose to Bitcoin and blockchain security.
Hundreds of crypto wallets across EVM-compatible chains have been drained in an ongoing attack, with investigators yet to identify the root cause or point of compromise.
