My suggestion for which links I would take:

My own suggestions: #28 (comment)

Plus from Emzy (because I have good insights to each of these):

• index: Fix coinstats overflow #30469 index: Fix coinstats overflow bitcoin/bitcoin#30469
• Eclipsing Bitcoin Nodes with BGP Interception Attacks https://delvingbitcoin.org/t/eclipsing-bitcoin-nodes-with-bgp-interception-attacks
• Sharing block templates https://delvingbitcoin.org/t/sharing-block-templates/1906
• Antoine: Misbehaving nodes https://antoinep.com/posts/misbehaving_nodes/

I'll prepare these if nothing changes, just let me know if this collides with your preferences.
