" So, Murch, Bitcoin uses 256-bit ECDSA but 256-bit ECDSA only provides 128-bit security. If I’m understanding the reason behind that, it’s that the reason that sipa points out here, that there are known algorithms that are more effective than just brute-forcing 256-bit keys, so that it’s technically then 128-bit security; am I getting that right? So yeah, I do think route boost is more of an interesting historical thing that was tried, but it didn’t really yield any meaningful result in practice, I believe. And in a way, blinded path makes that easier, because with blinded path, blinded path is a way to doing some route boost without actually telling people about the channels. Bastien Teinturier: Yeah, and in a way, blinded path will just allow you to do that again because whenever you choose your blinded path, you can choose to make them go through your friend who wants to collect some fees through exactly the channels where you need them, when you know you have a lot of inbound liquidity and want to balance the channel. You would just include them in your blinded path, people don’t even have to know what channel this is, but you kind of force them to go to a direction where you know that there is liquidity

Murch, do you have comments on the release more generally? Mark Erhardt: I think that there might also be a couple of issues here with if you, for example, have one peer that you closely work with and you want to funnel more fees to, you could always route boost them and then make sure that they collect the fees rather than other peers you have, which may be sort of a downside of prioritizing boosted peers. Mark Erhardt: Yeah, so for this one, we have a small update for how PSBTs are shown in the GUI. First one, HWI 2.3.0, which has a few items from the release notes that I think are worth talking about. Binance stays in the headlines being the biggest Crypto exchange in the World by volume, but in the last few days it got more space on the newswires with some major announcements from the Crypto behemoth. And we’ve covered a lot of these PRs as they were merged to the LDK repository over the last few weeks. Mike Schmidt: Last question from the Stack Exchange is, "What does it mean that the security of 256-bit ECDSA, and therefore Bitcoin keys, is 128 bit

Mike Schmidt: The person asking this question was also asking about seed security and was maybe mixing up this 256-bit ECDSA versus 128 versus like the security of a seed, which sometimes can be 512. So, there’s some details in the answer on the Stack Exchange there. What does it mean that the security of 256-bit ECDSA, and therefore Bitcoin keys, is 128 bits? Because, if you try to replicate a hash, https://m.blog.naver.com/ajjuguru/223415792391 an exact hash, without knowing the input, I think you do have 256-bit security. Do you have more to add here on route boost? So, you could sort of ask that people route through specific channels because that one is especially lopsided and it would move the liquidity more in the direction that would balance out the channel, which would be a good thing. 256 cover some of these PRs in more detail. 256 for some of our discussion about these individual PRs. Let us find out what makes Bitcoin so valuable and acceptable. But if you’re trying to replicate a hash by knowing when you know the input message before the hash, the pre-image, then it’s only a 128-bit security because you sort of have to find two things that produce the same digest rather than needing to replicate one di

But there’s also this technique that Christian Decker mentioned in his answer to this question on the Stack Exchange, which is route boost, which means that I can also provide some sort of hints about channels that I’m aware of that have adequate capacity for the payment that I wish to receive. So, you can run Jade on non-Blockstream hardware, and now with this HWI 2.3.0 release, you can also now use HWI with those DIY devices. So, there actually are a number of different hardware devices that can run the Jade firmware. Binance trading is accessible via multiple devices. Although the provider was launched as recently as late 2017, it’s often facilitated over $2 billion worth of daily trading activity. But it’s really the recipient’s decision to whether they want to use it or not. While at the time of writing this is only available in a select number of nation states, it is likely that Binance will continue to roll out it’s credit card and bank transfer facilities over the coming months.
