BIP 54 debate resurfaces, focusing on coinbase transaction modifications and ASIC optimization concerns.

Jeremy Rubin proposes a new sparse Merkle tree, avoiding 64-byte transaction size restrictions.

Consensus favors pragmatic solutions, balancing innovation with stability, avoiding drastic protocol changes.

BIP-352's scanning method in Silent Payments shows significant performance issues with adversarial transactions.

A new proposal suggests a "K_max" protocol limit to improve efficiency without affecting current SP wallets.

Broad community engagement is sought via GitHub and mailing lists to refine the proposed protocol enhancement.

The new Tapscript opcode, **OP_CHECKCONSOLIDATION (OP_CC)**, enhances Bitcoin consolidation efficiency.

**OP_CC** allows bypassing individual signatures for subsequent inputs from the same scriptPubKey (SPK).

This method significantly reduces blockchain space and data by making transactions more space-efficient.

Ethan Heilman and colleagues have rewritten BIP 360 for clarity and quantum risk mitigation.

The revision introduces "Pay-to-Tapscript-Hash" to strengthen Bitcoin's quantum resistance.

It adds test vectors and encourages community feedback for Bitcoin's security enhancement.

Dust attacks on on-chain wallets pose significant risks by linking UTXOs to reveal user connections.

Proposed solutions include spending dust UTXOs on fees with specific transactions, feasible with lowered fee rates.

Implementation challenges include potential user fingerprinting, rebroadcasting issues, and multisig device complications.
