 Hello everyone to the peer-to-peer technologies and blockchain session. The background context for this whole workshop goes back to the beginnings of times, when the ethereum founders realized very early on that the public blockchain is basically the final missing piece in the puzzle in atrežiča ko vzigljali naite vsoočenje. Kako je izvežila srednji drim vzigljali naite vsoočenje. In jo, še sem rovljala idej z kakožim, da ste odbožite nekaj etereju ekosystemom, nekaj se je uhmet na vsevživnje vsevživnje, ki da moreš kakva radnjela za nažitom, z Toma državo. In tudi transkranje je srednjet, nekaj nekaj treba bez koril? Daj se však vzelnje in trajet bleedingi. V zelo ,,I.O." je tudi, ki je spremnjela, zača vzela za nasak, In druga pilara je izgleda za komunikacije. Zdaj, da je bil veliko odličil in vse projekte je zelo v skopu. Vse vse projekte, da sem izgleda vse projekte, To je kajno, kajno došli projekti, ki so došli do vrštih. Jih je vzvečen, da so priježili vzvečen je naši takrat, in tudi je odličati do vrštih teknoločnih. Zelo vse sem izvedal, da smo prišli došli, zelo je jezivstvena z vsega. Zelo je skupnjak, z nami pozavljenja, V pomečnih naših skopih? Pomečno decir, da je bilo zavrčen, da je bilo tukaj konec in koment in tako drženje, dokončne in vrtečne, vsega začnega. Predvaj smo odličilo, da je tukaj zvrčen in to ima začin na začin in tudi v nekaj baseljevnih servici, ki je zelo zbarno na internetu, našli na vso vznik v tem, da je več vznik, in tudi vznik vznik in tudi vznik, ki je vso vznik vznik, da je vznik, da je vznik, da je vznik na tezvim ekosistem, je več vznik, da je vznik vznik vznik, da je vznik vznik vzniku, da je vznik vznik, The web stack and most real time interactive applications nowadays based on some central database components. It's a database driven so if we provide some tools how to handle or how to manage these databases in the new paradigm of the decentralized Internet then we can help the adoption or those are helping migrating current web solutions to the new paradigm. So today we are going to see a lot of interesting presentations and especially I'm very happy to say that some of these are quite mature to the extent that we are going to have the possibility So, in the first hall before the lunch break, Aaron and I will talk about Swap-Swern and Swindle games. The context for this is to provide some infrastructure for accounting and providing kontraks for decentralized services and provide efficient payment solutions, basically micropayment solutions, which allow users to save on transaction cost, as opposed to on-chain direct payments. So we're going to talk about that first, and then we're going to have a session on TrueBit, which is basically off-chain verification of computation. And right after the lunch break, we're going to have the live peer, who are presenting a solution using Swarm to stream media files, audio and video. They're going to have demos as well. And then we're going to have another streaming-related talk by streamer. Later in the session, we're going to have a talk about PSS. PSS is our not-to-not messaging service on Swarm. And very closely related to that, the mainframe is going to present their communication solution based on PSS, which is basically a slack-like alternative communication, like chat client. And this will have audience participation. So please be prepared with your gadgets if you want to take part. After that, we're going to have presentations by BigChainDB. And to close the session, I'm going to present some kind of, instead of a proper talk, I will just present some ideas and start a conversation about how to do the decentralized database services using our ecosystem, and what are the challenges and what are the requirements that we need to have proper decentralized services doing databases. So I hope that you're going to enjoy these sessions. And now without further ado, I give it over to Aaron to start the talk about PSS. So, enjoy.
