6. Segregated Witness (SegWit) fixes transaction malleability while boosting blockchain capacity
7. Lightning Network enables instant micropayments through off-chain transaction channels
8. Multi-signature wallets require multiple approvals for enhanced security controls
9. Proof-of-work mining makes rewriting transaction history economically unfeasible
10. Bitcoin script allows programmable money through basic smart contract functionality
11. Full nodes enforce network rules by independently validating every transaction
12. Hardware wallets isolate private keys from internet-connected devices for protection
