Oil prices hit a 3-year high, natural gas demand far outstripping supply as northern hemisphere approaches winter - any surprise that China renews crack-down on BTC mining as they face an energy crisis? The world needs a more energy efficient crypto. #ProofOfStake #Cardano

@Sam52608971 @benohanlon @IOHK_Charles We have an upcoming change in the rewards formula (a0 pledge benefit) that will move in this direction: making the impact of pledge proportional to the size of the pool, rather than the *maximum* size of a pool.

[Colin Edwards @TopCat0112358]

@AltzPool @KpunToN00b @IOHK_Charles @InputOutputHK A formula change needs to go out with a hard fork; the pipelines for those get set well in advance.

[Colin Edwards @TopCat0112358]

@bigpey K is not changing in the short term; it will not happen until after the pledge benefit (a0) change goes live. Early Q3 is the guidance I have right now for that, given the other work in the pipeline.

@WiseCapital3 @adatainment @Bakyt_AA @cardano_journal @block_writer @FaourNazim @timbharrison @PfeiferHinrich @HendrikxAndy @T_Serodio @JeremyFirsterCF @F_Gregaard @mccanndublin I hear your concerns; I get that a lot of smaller pools feel invisible and undesired. The particular issue of concentration of ownership is one we have been focusing on - with a lot of success as the more recent charts show.

[Colin Edwards @TopCat0112358]

@WiseCapital3 I think https://t.co/3XA4023VHw has updated versions of those. I find their stuff to be quite reliable as well; if you see a big difference there I would like to know!

@WiseCapital3 @Bakyt_AA @cardano_journal @block_writer @FaourNazim @timbharrison @PfeiferHinrich @adatainment @HendrikxAndy @T_Serodio @JeremyFirsterCF @F_Gregaard @mccanndublin For what its worth, the numbers at https://t.co/oTUwa9rhaG are within a percent or two of mine; I believe them to be reliable.

@WiseCapital3 @JeremyFirsterCF @Bakyt_AA @cardano_journal @block_writer @FaourNazim @timbharrison @PfeiferHinrich @adatainment @HendrikxAndy @T_Serodio @F_Gregaard @mccanndublin I calculate it between 1.5 and 2 MM: 32e9 ada × 75% participation / 21600 blocks/epoch = an effective limit on minimum pool sizes.

@RealSaidov @jdorman81 @IOHK_Charles That's a longer discussion than a tweet. Marginal utility is probably a better framework than DCF for valuation though, so asking the wrong question. People over focus on price; 100% more thrilled about the price stability vs market downside this month.

Just found these guys; how did I not know about them before?

@RealSaidov @shawn_mcmurdo @LarsBrunjes @IOHK_Charles I am not a game theory guy though - I look at stuff like discounted cashflows, operating at a loss to attract delegation and arbitrage! The Nash Equilibrium game theory crowd may have different ideas!

[Colin Edwards @TopCat0112358]

@RealSaidov @shawn_mcmurdo @LarsBrunjes @IOHK_Charles The key elements in all "good" a0 solutions for me: ensure that splitting pledge equally between pools is always the worst outcome, have the impact large enough to be meaningful, be able to tweak the level safely.

[Colin Edwards @TopCat0112358]

@5050isaloss @marshosaurus This is what I see: a couple different options and one of them is "metadata". (But I agree, this is a huge problem for crypto - the answer to "how to you achieve financial inclusion?" is not "start by downloading a full node wallet", we really need to lower the bar.)

@rickmccracken I wish I could claim it was my idea - I just stumbled across it!

[Colin Edwards @TopCat0112358]

@cool_stake @rickmccracken Tangential to your point: the @shawn_mcmurdo CIP focuses on making smaller levels of pledge more meaningful, but because it is smaller pledge levels, it has a much reduced impact on how quickly the reserve gets drawn down.

[Colin Edwards @TopCat0112358]

@awildthingy @rickmccracken a0 represents additional rewards given to pools with a higher amount of pledge. It decides whether it is more efficient to split pledge across multiple pools (for extra delegation) or to concentrate it in a single pool for enhanced rewards.
