miners who have made a long-term capital investment in mining equipment might instead prefer to optimize fee income over multiple blocks</a> It's also possible that owners of ASICs or pool operators will decide that they're in this for the long term, and therefore that it's smarter to look at fee income over multiple blocks, rather than taking each block as its own entity. Similar to treating the prisoner's dilemma as a one-off game (where the dominant strategy is to always defect) versus an iterated game (where cooperation or tit-for-tat may be better strategies).</em></li>

</ul>
New Work & Research</h2>

Gleb Naumenko, with contributions from Antoine Riard, discusses bribing miners to censor specific transactions, "TxWithhold smart contracts"</a>. Interestingly, one do so is probably via Ethereum, which already has the equivalent of on-chain Bitcoin SPV clients. Bitcoin developers should probably be at least peripherally aware of such potential interactions with other chains. Additionally, UTXO set inspection is impossible today, but could be accidentally added to the protocol.</li>

Cryptography</h2>

Were X-only pubkeys a mistake? Maybe, because they make a bunch of protocols more complicated, but maybe it's not so bad if we only use them at the very end, just-in-time X-only pubkeys, if you will.</a>. Great comment here</a> by real-or-random.</li>
Apparently you can non-interactively half-aggregate BIP-340 signatures, who knew?</a> But this breaks adapter signatures</a>) so it's kind of a monkey's-paw type situation. Why? Because the untweaked signature is never published on-chain, only the tweaked signature.</li>
Order is hard. How to make your mnemonic a little longer but the order doesn't matter.</a></li>

How much entropy is lost alphabetizing your mnemonics?</a> - 500 million x speedup for 12 words and getting close to practical, 0.5 septillion for 24 but way beyond feasible. This kind of stuff is interesting, since I think brain wallets where you memorize your passphrase have legitimate uses, for example when in duress, fleeing, imprisoned, etc. So things which modify passphrase generation such that they are easier to memorize, such as alphabetizing them, are worth considering, to answer the question: What is the best way to generate a mnemonic that can be memorized and retain as much entropy as possible? The answer to the question goes deep into some of the math involved. Question for discussion: When is memorizing a passphrase a good idea, if ever?</li>
