VanitySearch VS VanityEth

I'm not endorsing this particular software - you should be extremely careful with how you generate keys for bitcoin addresses, they are very precious and must be kept secure and secret - but here's an example piece of software that does the search: https://github.com/JeanLucPons/VanitySearch

using https://github.com/MyEtherWallet/VanityEth directly from terminal is orders of magnitudes faster. a 4 character prefix is generated in less than a second compared to the 1.5 minutes of in-browser generator. I imagine customizing it to use GPU or even FPGA/ASIC could get a few more orders of magnitude. It isn't safe to rely purely on prefix and/or suffix checking

Fun Fact: Wallets with leading zeros use less gas when storing information because there is less memory required to keep these values. You can find more information here. As a result, you may see web3 developers online where their handles are the first few digits of their public key. The public key serves as proof of their activity on-chain since anyone can use a network explorer to view the activity associated with a public key.

btw/ There is a thing to create vanity addresses if you want 0xDEADBEEF or whatever https://github.com/MyEtherWallet/VanityEth
