BIP-360's update enhances Bitcoin's defense against quantum computing by modifying P2QRH to use Taproot.
The changes simplify implementation, improve security against quantum attacks, and offer a non-emergency adaptation strategy.
A future plan for Post-Quantum signatures is outlined, allowing separate development and integration into Bitcoin's protocol.

Selfish mining strategy allows miners to gain more than their fair network share.
Profitability of selfish mining depends on the miner's hashrate and block propagation speed.
Analysis and simulation show profitability threshold lies around 36%-37% of network hashrate.

Nostr uses cryptographic techniques like Bitcoin for key generation and receiving Bitcoin payments.
It introduces a method to improve user experience by notifying through encrypted messages via NIP-17.
The proof of concept with Python code demonstrates creating stealth keys for private transactions within Nostr.
