VanityEth VS profanity

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

But it has been cracked in some cases such as cracking a poor implementation of a random function... e.g. what happened with profanity using 32 bit seeds which can be done on consumer gpus and not super computers https://github.com/johguse/profanity/issues/61

eg this software was open-source but no body reviewed it. People found an issue and 6 months later it was exploited https://github.com/johguse/profanity/issues/61

4/ Although the number of public addresses created with Profanity is unknown, the project's GitHub source has been forked hundreds of times.

Part of the issue is the limited seed (32 bit int): https://github.com/johguse/profanity/issues/61
