@kallewoof If I'm correct, the rationale here is that the first action of an evil actor with a QC would be to destroy Bitcoin. IMHO, this hypothesis is questiionable. I would even say that a smart evil actor with a QC would first try to enjoy the benefits of his new tool while staying under the radar. For example, it would be smarter to start with the hack of exchanges which frequently reuse addresses. And who is surprised by the hack of a cryptoexchange ?

@kallewoof Let's take the example of an evil state. For sure, this evil state would be fine with a world without Bitcoin but it would be far smarter for this state to keep bitcoin running and enjoy some free money (for blackops, paiement of ransoms, etc) by hacking services or wallets which reuse addresses. It just requires some basic blockchain analysis... and a QC.

@kallewoof Let's also note that this strategy is a double win for an evil state. Beyond enjoying some free money, it also damages the reputation of Bitcoin ("See, this Bitcoin thing is insecure, people are always hacked,", etc). A nice way to control its spreading and to shill fiat money.

@waxwing well, this work is produced by machines which are operated/controlled by human entities. It seems difficult to deny this point.

@waxwing My answer to her question was that miners can't be considered intermediarires between the payer and the payee.One may argue that miners stand between the payer and the blockchain but the blickchain isn't an entity. Thus, a term like producers seems more adequate than middlemen.

@waxwing Greed is a powerful force. Often chaotic. Sometimes destructive.To me, the real genius of Bitcoin is this idea of a system funneling and transforming this chaotic force into the fuel of a positive outcome (network security, growing network effect, etc).This is truly psychological aikido. 😃

@Sosthene @lukedashjr The challenge is that this theory is based on the self-referencing hypothesis that you have the right to fight for your rights. At best, you can consider this hypothesis as an axiom (~write it in the constitution). But, as maths teach us, people love to play with axioms (by removing or weakening them) because it leads to brand new geometries (models of societies).

@Sosthene @lukedashjr I agree about this. People will fight to protect their life and their family. But, it's not about human rights anymore. It's our animal inheritance. Actually, I think that a lot of these discussions are often about how much of this animal inheritance is acceptable in our society.

@waxwing I like this idea that was also proposed by Hugo Nguyen.I tend to agree that some of the "constraints" associated to the physical aspects of PoW create an inertia that is part of the security model.It raises interesting questions about the PoS model,. Especially if you envision it as a " virtualized PoW" as it's done for ETH. And the most obvious question is if it's a good idea for a PoS system to get rid of PoW's inertia or if it should be reintroduced artificially.

@htimsxela @waxwing Indeed, lockup periods are a good example but it could be any mechanism/rule introducing "inertia"/"friction" in the system for the sake of improved security.

Any thought about this? (figure also confirmed by coindance, -in term of number of new full nodes)https://twitter.com/bastienchanot/status/1213531506326540289?s=20

@waxwing FWIW, Samourai's implementation of 2-party coinjoin (Stonewallx2) consistently provides this property (e.g.: https://oxt.me/transaction/tiid/2588489123)

@waxwing It reminds me of some thought experiments while writing a series of posts about PoW:- UTXOs as "particles" moving in a 1D space,- Work acting as a force "accelerating" UTXOs,- Principle of inertia applied to UTXOs is what secures the UTXOs, - etcThe great irony is that I don't even think that it's a good idea to use a newtonian model when dealing with a complex systems like Bitcoin. But it's hard to resist the pleasure of playing with analogies. :D

@waxwing Anyway, that was instructive. This is how I learned that the idea of using netwonian models in economics was popularized by Cantillon and later by the Physiocrats.

@htimsxela @waxwing What I call "Newtonian model" in this context is the conceptual framework built around the core concept of deterministic reversible trajectories ruled by differential equations.My guess is that the main motivation of Cantillon was to show that the economy of a society follows a natural order that can be studied and understood. Thus, taking inspiration from the Newtonian model made sense since it was cutting-edge maths used to describe natural order.

As a side note, just a shower thought about the role of time in these models and in Bitcoin...A "funny" thing about the Newtonian model is the reversibility of time in its equations (something that is the complete opposite of our intuition of the existence of an arrow of time).Thermodynamics has reintroduced the idea of an arrow of time with its 2nd principle. This was pushed even further by researchers like Prigogyne (works on dissipative structures).

@Sosthene @verretor C'est surement trop tôt pour le dire mais je ne serais pas surpris que son analyse soit juste sur nombre de points.

@Sosthene @verretor Fun fact: when I was a kid, my grandmother made me drink "quinquina" which is basically quinine in red wine. "It's good for your health" 😊

@waxwing @lukedashjr We (oxt research) have started an investigation of these 1-of-1 addresses (code name Crazy1o1).First results:https://twitter.com/LaurentMT/status/1264586463536189444?s=20https://twitter.com/LaurentMT/status/1264958123275681793?s=20Since these tweets were published, we have identified ~3.7M of P2SH and P2WSH 1-of-1 addresses in this cluster and I think the final figure should be ~4M.AFAICT, this entity has played a huge role in the last fee spike.
