[JOURNAL] Week 1

[RajWorking]

1. Why npm rebuild and not npm install?

Node modules are stored on github, not relying on npm

gpk, nodegyp - language bindings between C++ and Javascript

2. I learned:

• bcoin has no signet like bitcoin-core
• regtest - no peers, only me in network, for learning and testing
• json RPC is similar to rest api
• Confirmed is a subset of unconfirmed and not mutually exclusive like bitcoincore

3. Still need to explore:

• Taproot
• apidocs

4. What I can do:

• use bcoin to develop some project
• improve bcoin by writing tests
• bring it to pace with bitcoin core by writing features that dont exist

[RajWorking]

What is a wallet token?

[pinheadmz]

Great job, Raj thanks for posting! One thing though - you posted a mnemonic seed phrase! (In your master command). This is a regtest node so no one can steal any real money from you but even still, it's good practice to avoid that ;-)
