Frequently Asked Questions

Does bitcoin use encryption?

No , Bitcoin does not use encryption. It's called "cryptocurrency" because its digital signature algorithm uses the same mathematical techniques used for a type of encryption based on elliptic curves. Bitcoin uses the Elliptic Curve Digital Signature Algorithm (ECDSA) with the elliptic curve secp256k1, not encryption.

What are some examples of cryptography?

Types of cryptography

  • Secret key cryptography. The Caesar cipher we discussed above is a great example of secret key cryptography. ...
  • Public key cryptography. Caesar may have been able to confer with his centurions in person, but you don't want to go into your bank and talk to the teller just ...
  • Hash functions. ...

What are public keys and private keys?

Public key and private key is a couple of keys used in public key cryptography. If the locking key is made public, then the unlocking key becomes the private key and vice versa. Public key cannot be used to derive the private key.

What is cryptography in blockchain?

A blockchain, originally block chain, is a growing list of records, called blocks, which are linked using cryptography. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data (generally represented as a merkle tree root hash).
