Last week, through the lens of
@Chaitika_ the focus was on Scripting, key control, and transaction-level behavior.
Script was approached through execution rather than abstraction, with emphasis on how outputs define spend conditions and how validation enforces them. P2PKH, P2SH, and P2WPKH were used as reference points, particularly in understanding SegWit’s role in transaction structure, weight, and malleability fixes.
Spending conditions were extended into multisig, timelocks, and HTLCs. This covered m-of-n authorization, absolute and relative timelocks via nLockTime and nSequence, and hashlock constructions for conditional flows.
On the security side, the discussion centered on key ownership. Authentication and authorization were separated at the wallet level, with cold storage treated as an operational necessity for minimizing key exposure.
Threat models focused on realistic vectors, including malware, phishing, and physical compromise.
At the transaction layer, signatures and fee rates were examined in relation to validation and mempool policy.
Privacy was discussed in terms of UTXO linkability, CoinJoin usage, and the impact of address reuse on traceability.
