The latest release of Bitcoin Core, v26.0, offers improvements to network connectivity and syncing speed for nodes. However, the upcoming release, v27, may stop the creation of new Bitcoin Ordinals due to their impact on blockchain congestion and increased transaction fees. The controversial Ordinals have exploited a vulnerability in Bitcoin Core and led to a resurgence in their activity, prompting the need for proactive measures to manage blockchain growth and congestion.


1. How can Bitcoin Core strike a balance between stability and reliability of the network while remaining open to new and potentially controversial ideas?

2. What impact does the congestion caused by Bitcoin Ordinals have on the usability of Bitcoin for payments, trading, and investment?

3. To what extent should the Bitcoin Core project intervene to address issues such as network congestion and excessive transaction fees caused by specific activities like Bitcoin Ordinals?
