 second question is before you had a very nice analogy between GPG and SSL and why the one is used by many people and what I'm not and that is well because the browser does everything for us very easily and the browser in Bitcoin is pretty much the as I see it is the Bitcoin wallet or yes whatever wallet you use and and I would love to see them on innovation that space so my question for you would be what features do you would love to see in future wallets should we focus on to make it more easy to use for the average person and more usable wallets are the the the fundamental nexus of innovation because they are the fundamental user interface they are the mechanism by which a person interacts with the system but also the same applies to API based systems where machines are interacting with the blockchain the Bitcoin blockchain or other open-block chains wallets their user interface their design characteristics their ease of use their workflows they are the basis by which we will understand or fail to understand this technology be able to use or fail to be able to use be able to expand or fail to expand this technology and you say there's not much innovation in wallets I accept that it seems again it seems very slow at first as it builds momentum I remember when there was one wallet for Bitcoin it was called QT and then we have lots of nodes on the network because you needed to run a full node just to have a wallet and now we don't have as many nodes and apparently that's a problem I remember the first SPV wallet I remember the first mobile wallet written on Android by Andrea Schilbach who I met recently in Berlin it's amazing person and that's the first mobile wallet I used and then there were two and from two we went to 20 and then from 20 we went to 200 and soon we'll have 20,000 wallets and most of them will be crap but in the process we now have five or six really really really good wallets wallets that offer us ease of use ease of backup extensibility recoverability resilience security okay I'm gonna do this I don't normally do this in public but I would like to say there are a bunch of people in this room who invented BIM 39 mnemonic phrases that completely revolutionized how easy wallets are to use so round of applause for that team I go around the world and I tell people your entire Bitcoin wallet can be sprayed as graffiti on a wall in the form of 12 English words and you can share that with the world how the hell do you stop that you can transmit your entire wallet by writing it on a piece of paper and recovering it memorizing 12 words walking across a tightly controlled border where currencies are confiscated and arrive on skates in the other side you can recover all of your transactions and all of your money wallets have made enormous progress in the last two years and I think we're missing the fact that they're getting even better several new features that are going to revolutionize wallets segregated witness with its ability to add commitment signatures to input values make wallets a lot easier to do especially offline wallets the ability to do lightweight transactions with segregated witness payment channels and lightning network will be mind-blowing in its applications for wallets and it's going to take at least three years until you see those applications but then they will accelerate and I hope to see a whole slew of wallets that are dedicated to specific communities wallets that support people with disabilities wallets that support people with all kinds of different languages and number systems and cultural practices etc and that's one of the things we have to realize which is we're going to get a lot of diversity here this is not going to be you know one or two wallets that everybody uses I mean that would be a disaster instead what I hope to see is a Pareto distribution of power wallets you have you know five or six wallets that have 60% of the user population and then you have 10,000 wallets each for a tiny tiny niche that serve many different purposes this is a brand new field it's growing very very fast momentum is picking up all of this is open source the various wallets use each other to discover new ways of doing things reusable payment codes is another fantastic innovation that gives you stealth addresses combined with hierarchical deterministic wallets that's been implemented in one of the wallets I was looking at recently which is called samurai wallets that's focused on privacy and the other really interesting feature is that you see wallets that are focused on solving specific needs some are about as I said ease of use some about convenience some about retail applications and some are about very very very strong privacy so I'm very optimistic about wallets
