Title: Comprehensive Article on Generating a Bitcoin Address Using JavaScript Post by: jp on August 27, 2013, 10:01:11 PM Hey guys, I noticed the lack of a comprehensive article out there that explains exactly how Bitcoin addresses are created. So, I did the research, and wrote one :) It's pretty in depth. I'd love any feedback, thanks!

There are some libraries like bitcoin-js that do accomplish that task, but they aren't very well documented, so your work is definitely welcome here.
One note - The version byte can have up to four valid values for Bitcoin network: - 0x00 - main network pubkey hash address - 0x05 - main network script hash address (e.g. multisig address) - 0x6F - test network pubkey hash address - 0xC4 - test network script hash address More information: https://en.bitcoin.it/wiki/List_of_address_prefixes Title: Re: Comprehensive Article on Generating a Bitcoin Address Using JavaScript Post by: hayek on August 28, 2013, 03:53:23 PM This was a great read

Jeff, it looks like you're one of the authors of the Node.js libcoin. I'm curious, why did you choose to do the ECC code in C++?

Using OpenSSL is important for bug-for-bug compatibility, even ignoring the performance improvements. |
