There's a whole spouse and children of these types of curves that happen to be widely known and applied. Bitcoin employs the secp256k1 curve. If you'd like to learn more about Elliptic Curve Cryptography, I’ll refer you to definitely this post.

Remember that as a result of its reputation and open up-supply character, Vanity-ETH has become broadly copied, resulting in the existence of websites claiming to provide exactly the same functionality. Sometimes, They are really great clones hosted on quite equivalent domains.

They are also marginally more secure than cell wallets, as They may be more unlikely for being misplaced or stolen.
