Coin.jl

A (self-educational, incomplete, and likely incorrect) library for working with Bitcoin written in Julia.

To Do

• https://en.bitcoin.it/wiki/Technical_background_of_Bitcoin_addresses
• TODO: multiple inputs
• TODO: convenience functions
• TODO: clean up and documentation
• TODO: update versioning info automatically (e.g., useragent, changelog, etc)

Wallet

First, we're going to implement a thin-client wallet.

• Should consider creating object types (e.g., addresses with metadata; wallets; etc)

• Clean up tests to make more consistent

• Different nets (e.g., https://github.com/haskoin/haskoin/blob/master/prodnet/Network/Haskoin/Constants.hs)
