## Featured Talks
## Day 1
### Web3 Communications
#### Viktor Tron
In this talk, we deconstruct digital communication modalities into functional components and show how these components can be implemented using core swarm features such as feeds, access control and PSS. We argue that as a consequence swarm can provide censorship-resistant, trustless and economically sustainable solutions for communications with strong privacy (eg. chat, file transfer, email, forums, blogs and comments).

##### About Viktor
Viktor Tron is team lead for the swarm project and has worked for the Ethereum Foundation since the start. Committed to the ideal of a free voluntary society, he has a keen interest in decentralisation, cryptography, networking, data structures and algorithms and believe in technology and innovation as the conduit for peaceful social change. A long-time contributor to the open source community he advocates open source, open data and open collaboration models, currently working on web3.

### Motivating increased participation with incentives
#### Racin Nygaard
This talk will mainly be focused on Proof-of-Storage and a discussion about how to fairly incentivise storage providers.

I plan to start the talk by introducing the document storage part of the BBChain project. The BBChain project envisions a global academic database for degree certificates, and to that end aims to verify document authenticity using biometric signatures of the students.

Following this introduction I want to have a high-level talk about the properties and features we desire in the Proof-of-Storage / Proof-of-Custody scheme. In particular I want to discuss the trade-offs which we foresee have to be considered in a practical system.

Lastly I want to talk briefly about how the PoS/PoC scheme is coupled with the incentive scheme, and provide motivation for why the incentive scheme is the primary mechanism for keeping rational participants contributing to the system.

##### About Racin
Racin Nygaard is a Research Fellow at the University of Stavanger. Racin is studying the feasibility of a distributed storage system for authenticated documents based on blockchain technology.

Racin received his Master’s degree in Computer Science at the University of Stavanger in June 2018, and has since then worked in the same lab towards his PhD. The topic of the concluding Master’s Thesis was Distributed Storage with Strong Data Integrity based on Blockchain Mechanisms. Recently, he presented a poster paper at ACM SAC 2019, DADS track, titled Distributed Storage System based on Permissioned Blockchain.

Racin worked full time as a senior software developer for five years before his academic positions.

### Decentralized Social Media Incentives
#### Daniel Nagy

For years, the creative content creation was financed either by enforcing
artificial restrictions on its -- by now essentially costless --
dissemination or by mixing it with advertizing messages so that consumers
could only enjoy it while being exposed to unsolicited advertizing. Both models'
shortcomings are abundantly clear by now, but satisfactory decentralized,
freedom-respecting alternatives have not yet displaced them.

In my presentation, I will explore such alternatives and how our
Swarm-based social media platform, Bee Free is going to facilitate their
implementation in practice. The new possibilities opened by
content-addressed distributed storage and the Ethereum blockchain can
hopefully unlock the creative potential of content creators and help
consumers find the kind of content that most interests them, while
contributing to its creation and dissemination in meaningful ways.

##### About Dani
Daniel A. Nagy, Ethereum Swarm architect and developer. Has been active in financial cryptography since 2008 at ePoint Systems Ltd. of which he is one of the founders.

### Entanglements and why I think they are a good feature for Swarm
#### Vero Estrada-Galiñanes
The BBChain project aims at providing permanent availability to authenticated documents such degree certificates.
Swarm offers a peer-to-peer storage solution with features that seem to be well-aligned with the storage requirements of BBChain.
The design of a decentralised system that guarantees long-term storage includes monetary incentives, some type of storage verification and a robust mechanism to increase the chances to recover files from unreliable nodes. P2P storage solutions require much more redundancy (and high fault-tolerance) than the usual redundancy used in centralised systems.
In this talk, I will focused on redundancy mechanisms to tolerate failures and in particular on alpha entanglement codes.
Alpha entanglement codes are a mechanism to propagate redundant information across a large scale distributed system and create a virtual storage layer of highly interconnected elements. These codes have a strong positive impact on data durability due to their ability to repair efficiently single and catastrophic failures. Unlike other codes, entanglements take advantage of the combinatorial effect while being less dependent on the availability of nodes in a distributed systems. Classical coding is more efficient than replication due to the combinatorial effect. However, in peer-to-peer systems, the negative effects of poor peer availability affects classical coding since the repair process depends on the availability of multiple locations. Alpha entanglements are less affected by the peer availability effect since only two blocks are used for repairs and they benefit from the combinatorial effect too due to the redundancy propagation.

##### About Vero

### Ways to scale sharing of encrypted data
#### Michael Egorov
The talk compares different ways to share encrypted data: one way is to use "updateable trees of keys", another is to use proxy re-encryption. The answer, which one to use, is different, depending on scaleability (in number of users, volume of data and time) requirements, as well as a threat model.

### Deploying and Managing Swarm with Kubernetes
#### Camron G. Levanger

Perhaps the most important aspect to realizing a permissionless and censorship-resistant network is decentralization. At Mainframe we have always tried to find new ways to make it easier not just to develop on Swarm, but also contribute back to the network.

Kubernetes can make contributing nodes to the Swarm network far less daunting than it might seem at first.

In this talk we will walk through setting up Kubernetes on AWS, as well as some of the finer points of getting your Swarm nodes running smooth. Logging, metrics, fault tolerance, and CI/CD will also be covered.

In addition to the walk through, open source versions of infrastructure automation for your AWS resources will also be provided.

### Treating Swarm as a Project Dependency
#### Camron G. Levanger
Working with a team of engineers in the same codebase can be problematic when it comes to project dependencies. While this is a problem that has been solved many times in various ways, here we will introduce a tool and methodology for treating Swarm as a dev dependency in your project.

- A simple command line tool and YAML file in your project will help make sure all engineers are developing against the same version of Swarm.
- Pin specific commits/tags/branches to specific versions of Swarm to cut out potential confusion from your workflows.
- Learn how to integrate these tools into CI/CD pipelines.
- Run multiple instances of any version of Swarm on any machine with a single, short command.
- Potential strategies for using the same tools to distribute your software built using Swarm.

### Multibox, a commons personal data storage on Swarm
#### Tadej Fius
Multibox is like mailbox on steroids, released under Fair Data Society. It’s personal data storage on Swarm that enables users to reclaim and own their data in one place, on Swarm. Moreover, Multibox enables developers to easily store app data into users storage and define their “protocol”. Furthermore, this is a first step towards fair exchange of data and new business models where developers can get compensated for the data that is created through use of their (d)app. Forget app monetisation through ads.

##### About Tadej

### Bringing Fairdrop into production with fds.js and Swarm
#### Dan Nickless
Fairdrop enables a secure and encrypted file transfer over Swarm and it provides a privacy centric alternative to centralised solutions. The talk will give a deep dive into the challenges presented in releasing Fairdrop dapp and how we overcame them during our journey to release a ‘totally decentralised’ production level app on the Ethereum and Swarm Web3 stack.

##### About Dan

### Fluence / Swarm as an external persistent storage to provide additional security for a decentralized data processing
#### Dmitry Kurinskiy
While the number of decentralized applications grows there’s still lack of a cost-efficient, fast, and secure way to work with all the kinds of data a modern application might need in a decentralised environment. DApps still have to rely on traditional ways to store, index, query and analyse the data.

While blockchains such as Ethereum are naturally designed to perform arbitrary computations, they are too expensive to handle any nontrivial amounts of data. In the centralized environment this problem is solved with a handful of services and tools (such as Kafka, Spark, Druid, Redis, etc.)

However, it is still hard to achieve similar results in the decentralized ecosystem.

Ideally, a decentralized data processing platform should allow building applications with throughput, latency, and cost efficiency comparable to the ones we see in the centralized world.

Fluence guarantees correctness of computations performed in a decentralized network, and at the same time allows building applications with throughput and latency similar to the centralized ones.

Fluence architecture includes several layers: real-time processing, batch validation layer, dispute resolution, data availability. As we exist in a thriving ecosystem, it is reasonable to rely on existing ideas and technologies. This approach allows us to rely on Ethereum ecosystem. In particular, we use Ethereum as a final source of truth, and rely on Swarm for persistent and secure data storage that also provides some degree of independence, redundancy, and transparency.

In this talk we will discover how Fluence enables new possibilities thanks to its architecture and ability to utilise what other infrastructural solutions have to offer.

##### About Dmitry
Software engineer, technical leader, CTO with solid expertise in complex engineering projects (algorithmic trading, smart food, delivery services). Functional programming and category theory adept.

### Swarm City & Fair Data Society - Building Decentralized Rideshare
#### Michael Thuy (@kingflurkel) & Gregor Žavcer

In order to create truly decentralized, peer-to-peer ridesharing, we must have decentralized data persistence and messaging. Swarm City is currently using IPFS and Whisper respectively, but neither is robust or reliable enough to accomplish the goal. To circumvent this, Swarm City created an API bridge, but this adds centralization to the ecosystem, which is unacceptable in the long term.

With Swarm we hope to realize our long-held dream of decentralized rideshare. In doing so we can together solve not only the data persistence and messaging problems, but also scaling, and anonymity.
