Understand how the network functions at a high level. We all understand PoW and the mempool at a high level. I want to have a good understanding of the following basic concepts to build on in the future: - how script works conceptually - what are UTXOs at the protocol level - How are they unlocked and locked using cryptography - public-private keys - How wallet addresses are derived - Difference between the kinds of wallets - What is P2x (P2SH, P2TR, etc) - Where off-chain protocols fit into the onchain transaction and how they are secure - What is client side validation - Risks of p2p networks vs global state This are a few that come to mind. I'm sure i'll find more as I dig into details. I will link anything I find useful in Friday's update. Let me know if you want me to add them here as well.
