Best answer


No, Bitcoin does not use encryption. It鈥檚 called 鈥渃ryptocurrency鈥?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.

  • Is bitcoin safe and secure?

  • Bitcoin technology is mostly safe because it鈥檚 built on secure technology: the blockchain. Bitcoin is also cryptographic, public, decentralized, and permissionless. As an investment though, Bitcoin may not be safe due to market volatility. Here are the four main reasons why Bitcoin tech is (mostly) safe: How is Bitcoin secure?

  • What are Bitcoin private keys and how do they work?

  • Private keys exist in many forms outside of Bitcoin for many purposes, and most people who are familiar with them from a previous experience would know them as a way to send encrypted messages. For every private key that exists in Bitcoin, there is a 1:1 relationship with something called a public key.
