Devcon 5 - Ethereum Swarm Breakout Sessions: Swarm Team AMA

[Music] yeah okay [Music] okay so a little pistol finally okay so so postage stamps are transmitted together learned each other during safety they're not transmitted during the requests so if somebody wants to download content you do not the postage they want the movement but if syncing is going on with syncing you send all the postage stamps together with the chance if nodes are leaving then syncing will gravitate more chunks towards you and you will observe more chunks being signed with that particular postage stamp and because of that your estimate if you have a question it's a rare opportunity to see us all in one place it's a timestamp part of the postage stamp data which is signed so is it possible to tell by looking at the poster spent for how old it is yes so whenever you pay so imagine so the analogy is that when you go to the post office you buy you know this huge four also of stamps and then you can stick them with all your letters so obviously since it happens on the blockchain there will it will be there will be a clearly marked time when you did that payment and also it does have an acceleration so postage stamps have a belated the period and that will live the period is publicly observable on the blockchain yeah so what you've been talking about now is like the the location of the content is based on the logic of your vocation of the tht right correct what happens if you have like files that are being actors mostly from a geographical location but they like in the logical they would be like uniformly distributed but that isn't necessarily over like geographical and it might be like super inefficient to host like a part of on one side of earth when the other side is where it's actually being hot like a great so this is what's cashing so this is one caching comes into play so as you have seen notes that the further away to notice from you the more selection you have so even the Tattaglia rules you're connected to the same number of beers in every woman but the bins that are further away from you you have more opportunities and you can pick those with which you have this shortest things so with those you will have a better better connectivity that kind of follows geography not necessarily physical geography but natural geography and because of that since caching is incentivized by swamp what will happen if something is select is continually requested from one area of the network that even though it is stored somewhere where it belongs because of its content address it will get cached along the route on all those nodes which are further away from the content but closer to the nodes that are requesting it and swap actually some devices that kind of caching so it is in the interest of them so it's not just that we program this thing to swarm there's actually an incentive to keep it that way so you cannot actually make money by you know we won't make that gold from from but even the closer note logically aren't like necessarily closer geographically right even if it's not efficient is going the logical location it will be spirited with at least whatever so he so the geographical notion location might might happen distribution forever I suppose I believe the way that should be stored in detention is regularly requested from a familiar for that kind of content all the caches in that area will be alright but how do I know that I will get connected to notes and because with no ones that are a little bit further away from you actually the further away the more choice you have so for example consider those notes with whom even the first bit of their swarm address is different from yours half just half the nodes in the network so from those half half the nodes in the network you can take the ones that are closest to the earth you will lose like lowest latency clothes lateness yes right okay so you think those questions we told the testing said that it's a it's a little bit easier ethically we don't have to speaking either it suggest in general to package this knowledge and to make it accessible we introduce also the strip process which this close to the VIP process to have discussions that have like yeah you could say compartment eyes focus knowledge gathering I'm positive that ain't and also Kadima is the fun in there the smooth yet in from code but at both PC and this is also a place to ask questions and to follow development process is primarily in that virtual components you can find a Research Forum by going to our website it means that missiles or I think it's a pretty open space yeah obviously this either sphere guitar people there let's go slash either spear slash snips yes all right do we have for another topic questions we get asked everything from from from business / incentives or to developments whatever you have on top of your mind [Music] is there any possibility to restrict access - I mean if both shares with Ellis something just published back in so in general access control so reading access is provided by the ability of the trip shop so for those kinds of access control your crib theta you don't share unencrypted data right with a specific set of users so there's a whole subsystem of swarm which deals with access control if you want to revoke access what you can do so they're say there's a process by which you can change a few things on this one I do not have to read the whole content you just change a few things and then when you keep you know updating that resource for that website that those who have been left out of the access control list they will not get updates like you cannot force them to like they can have a backup of what they have read once so if you have access to something it cannot be taken away from you it's impossible just like in you know you can make a backup copy of anything that you ever have access to great so that cannot be restricted however if that content changes in the future then those who have been excluded from the access control list the updates they will not be able to decrypt up so we'll do that students make the first content that we spoke was accessible to the net the nature cannot be removed because once what seems legal environments regulations pretend that this mechanism and then people should have the right to somewhat somewhat have a pretty similar way that market context you have to pretend that access is is access is actually more than by the current access code then then that's good that's considered so if the legal whatever can pretend that things can be unseen and then then you see maybe see might resent that eventually remove someone from the nexus control that's how you that's how you define that they're right I'm not sure about this is kind of like or you [Music] like like small forgets most warmest water system their stores forever and this is a very specific difference to my ship is just intense and a peasant has the huge archive which might need to be accessible and there may be some it's a technical limitation I'm not sure so that's that's why it's a philosophical question I wanted to get a survey whoo-hoo even it's not something like let's keep that short quick show of hands who wants to build something which archive something forever yeah yeah everything interest systems everything that someone is interested to pay for everything I don't know - remember that it's a cost and if someone is willing to pay for that question I would ask depressional also of nature like a teenager everything is irrelevant as requested right smooth things which are relevant there is a need for it and they stay relevant because interesting so I raise so I don't think there is a uniform answer it's like having said this I do have the domain Library of Alexandria that I want to give into public use one day so I don't think it's like a black and white question very difficult if you if you actually implement something that is able to forget the this is a very difficult topic because you make such possibilities of divisions when you were opening all the doors of perception yeah laughs quite recently announced that they will start that's that's pretty soon and they blend blend 2020 but they will make of their progress or their their approach how the fashion yeah well look what we've made about at night how about what do you think about that broke us that without chicken table and then we're very soon it's interesting I was like to pull an accession to do more thing because you compared a lot swarm and IPS in the last months and I would have to hear European about this yeah so we looked in but can you said what he said weird I mean I only lie or he lives and I'll be like yeah so be evaluated those two options the thing is that it was some three months ago and Paul Cohen still was not really clear has been soon-to-be-released on the test that the last tweeters as far as I remember I would also that being said I didn't I didn't for the last month's I didn't really kept up to pay all coin however when we looked at that what wasn't clear was how can we actually integrate with PowerPoint because Bible coin and ipfs is a very complex system that's just very close to any outside would say integration and if you like that whereas first beliefs for me has it's like the agitator it's totally different systems and also the invention or Sato facilities maybe we can move to a less competitive questions basically what's where she usually basically my baby right inclusive that's why I mean from the start and analysis that solutions for each wing eyes with with these into first shortly with a five-point he doesn't earn money for storing your files but nobody loses money if they lose your files and we need both sides whatever real guarantee because the file part some some other file pays more than future thinking us teachers there's no penalty for deleting and accept an opportunity custody and that's really what we're targeting with our storage incentive some related question but not talking about competition Danny his thought when showed that the incentive ation like a priority is to provide a reciprocal service does it mean that then is Swan who wants to create some kind of collaboratory current system like more than that that rather than having people that want to purchase a storage no than people that don't want to have any storage now that just paid swamp all three all three of these options are available so I think that the greatest inspiration for swarm with interent so I think that the Internet is a very very fundamental development on the internet it's a real innovation that happened in the early 2000s and the way they think they have this tit for tat protocol but you can only bail by reciprocal service and that is what ensures the item basically will be to the page from their experience that it's really nice that basically it were there to download you have to open up your house 300 which you've got me that they were not moving and you set aside a little bit of storage and you can do the same in swarm then the fact that you have some available resources it's easy it will be easier for you to just put those resources to use for others in the same network but if you don't have those resources it has to be right now so it's both ways and if you have recipient about you just have a big big data sometimes a fat pipe you can put it to use and you will repeat their without like that's exactly where that machines that and the system so it's like we don't have to - that sport that's what maybe that and similarly you're not forced to think on this for example if you have a cellphone you want you want BitTorrent use with your cell phone because it will drain your battery will drain your your account and so on so then you just want to pay and download and you got that option this one all right me too unfortunately a clean out the room and the conference time is ending so the most important thing for this project is cooperation in having the right partnerships and bring it to usage so thank you all for taking part in that
