BIP 3 was proposed in March 2025 after finishing work in February and has been adjusted since.

Over 600 comments on GitHub and discussions on Bitcoin Development Mailing List show significant interest in BIP 3.

Changes include adopting SPDX License Expressions and refining BIP text for clarity and proposal viability.

The email proposes a novel method for filtering objectionable Bitcoin blockchain content without harming its integrity.

It introduces a technique for maintaining data integrity post-deletion using specific internal hashing states.

The approach encourages collaboration on content moderation while respecting blockchain's foundational principles.

Hash-based cryptographic solutions for Bitcoin focus on security against quantum attacks.

Optimizations in signature size have made hash-based schemes more practical for Bitcoin.

The discussion invites the Bitcoin community to explore the practicality of these solutions for long-term security.

The proposal suggests a soft-fork for age-based expiration of dust outputs to reduce UTXO set clutter.

Since 2023, the UTXO set size doubled to 11 GB, mainly due to spam attacks.

Implementing a rule to make old, tiny outputs unspendable aims to diminish UTXO set size.

A new Tapscript leaf version aims to mitigate denial-of-service attacks by introducing a varops budget.

Benchmarking with block-sized scripts ensures the varops budget's efficiency, with a focus on transaction-weight correlation.

Community involvement is critical in refining the varops budget through benchmarking and contribution to the GSR prototype.

Several mining pools plan to support mining of non-standard, oversized Bitcoin transactions.

A proposed rule modification aims to allow certain heavy transactions without disrupting block creation.

The discussion on this topic underlines concerns about Bitcoin's future decentralization and network integrity.
