![]() Micropayments are handled by a custom chequebook smart contract and we are actively looking to integrate full payment channels as well. The dynamics of this system suggest that popular content will automatically become more widely distributed and faster to access. The Swap system accounts for bandwidth usage and compensates nodes for serving up content. It is built around three pillars which we call Swap, Swear and Swindle. In this talk we want to introduce the swarm incentive system. The Swarm network is uniquely able to address these needs due to the new opportunities ethereum offers in the form of micro payments and smart-contract governed incentive schemes. Swarm Incentivisation A robust peer-to-peer content storage and retrieval system requires a careful balance between the needs of the service providers and those of the consumers. ![]() Swap, Swear and Swindle Swarm Incentivisation for more flexible controlling of the anonymous execution of analysis code against a provided data stream with full transparency for the data provider and execution guarantee for the code provider. Smart contracts seem to leak into a role where they extend the power of digitally signed parameters to trustable scripts, which can allow e.g. It’s along those lines that Lua developed from a parameter definition language into a powerful script language. Parameters often power creep from static values, over macros to full blown scripts. ![]() In platform systems, users will define parameters to control part of a pre-programmed environment in ways that they need it. Parameters of a system can ever only be as powerful as the code they are controlling. However, a different use for smart contracts seems to be emerging that may not be along the lines they are currently understood: instead of facilitating self executing agreements and payments, they can be useful for user parametrization of complex workloads. Especially if there is no use for smart contracts or on-chain code, using Ethereum would usually create too much overhead. Other technologies should usually be used to implement an immutable ledger. Mistaking blockchain for a distributed ledger usually leads to wrong ideas and broken designs. Smart Contracts as Parametrization: Why the DLT Talk Can Make Sense The aim of this talk is to launch an important collaboration between the Ethereum and IPFS communities. This talk compares libp2p and devp2p, traces their concurrent history, discusses protocol differences and similarities, and suggests important areas of future collaboration and synthesis of efforts. It uses RLPx for authentication, stream multiplexing, network forming, and protocol multiplexing. ![]() It also defines a set of networking and peer-to-peer protocols. The coolest thing? It also runs entirely on the browser! devp2p is the secure networking suite that powers Ethereum. libp2p handles Authentication, Transports, Stream Multiplexing, Peer Discovery, Peer Routing, Content Routing, NAT Traversal, and Relay. It uses multiformats for self-description, avoiding algorithm lock-in, and cryptographic agility. It defines a set of interfaces for common networking and peer-to-peer protocols. Libp2p is the modular secure networking suite that powers IPFS. Libp2p ❤ devp2p: IPFS and Ethereum Networking In particular, the basic building blocks of decentralized, community-moderated knowledge bases (such as maps or encyclopediae), social networks and other forms of information aggregation are going to be presented. Using these examples as illustrations, the presentation will introduce prospective developers to techniques and approaches of both replicating Web 2.0 patterns in a decentralized fashion and going beyond their limitations, taking full advantage of content-addressed storage and blockchain-arbitrated interactions. In addition to developing the underlying infrastructure, the Swarm team also develops some example applications that, while useful themselves for end users, are also meant as a template and a starting point for independent developers. In my presentation, I will introduce some of the principles and practices of architecting and developing such applications, highlighting both the challenges and the unique opportunities for transcending the limitations of the client-server model. On one hand, such đapps’ approach to scalability is more natural as the computing power and bandwidth available for applications grows in proportion to their user base, while on the other hand the lack of a centralized trusted infrastructure under the control of a single - typically corporate - entity raises unique challenges in trust, reliability and coordination. Developing Scalable Decentralized Applications for Swarm & Ethereumīlockchain-coordinated decentralized applications represent a radical departure from the client-server model on which most of the currently popular web applications are based.
