Mastering Bitcoin Examples using Bcoin

In this post, we are rewriting some of the examples from the book Mastering Bitcoin by Andreas Antonopoulos using Javascript. Most of these programs require a bitcoin library to execute and for that we will use bcoin. For string encodings, we will use bstring and for cryptographic hash functions, we will use bcrypto.

bcoin functions used

1. bcoin.HDPrivateKey.generate() - generates an object containing private key, public key, and other attributes.
2. bcoin.Address.fromScripthash() - returns an address from a script hash.
3. bcoin.Script.fromAddress() - returns a script from a base58 encoded bitcoin address.
4. bcoin.util.revHex() - returns the reverse of a hex string.

bcrypto functions used

1. bcrypto.RIPEMD160.digest() - returns the RIPEMD160 cryptographic hash.
2. bcrypto.SHA256.digest() - returns the SHA256 cryptographic hash.

bstring functions used

1. base58.encode() - encodes a string into base58 format.
