• NBDN: Exploring the current state of Crypto-Tools with friends

    Nashville Entrepreneur Center

    Kicking off the new year right! NBDN will have a special meetup on Jan. 10th; we will be checking out some of ways to use crypto-tools in different and exciting ways. First off we will be using Kickback for this event registration if you’d like to partake in the free food and drink! Every person who registers with kickback will need a bit of ether (approx $5) that goes into the pot, this ether will be returned to you if you attend the meetup, otherwise it will go into a pot that’s re-distributed to everyone who does attend; read more about kickback here https://kickback.events/ If you need a wallet to use we suggest https://status.im/ for mobile or https://metamask.io/ for desktop. Event registration is here to get the free food & drinks at this event please RSVP and register at this link: https://kickback.events/event/0x842362abebc36e83265c793387ff12c9fb3650bc If you run into any problems RSVP’ing with kickback please reach out to one of our co-organizers! Take a look at the walk through at this link: https://www.evernote.com/l/AGuKe06RJT1JxKQKUE8TKSkiYVsvL-s_9hw We’ll follow this registration with a few 10-15 minute lightning talks on some of the respective projects we’re involved with or interested in. Chris Hutchinson will be giving a demo of the latest functionality of Status, a mobile chat client built entirely on ethereum. Status allows you to interact with smart contracts and chats in a secure and private way, and also has a browser and wallet built in. https://status.im/ Scott Lewis will be giving a demo of Settle. Settle is a web-native operating system for decentralized finance.

  • NBDN: Althea Mesh - Justin Kilpatrick

    Nashville Entrepreneur Center

    More info and links to slides can be found at this meetups minutes page. http://bit.ly/NBDNAltheaMinutes Join us this month for special guest Justin Kilpatrick who will be doing a rundown and interactive display of Althea mesh network. Heres a rundown on what problems Althea hopes to solve: Because today’s ISPs are often monopolies in the markets they serve, they’re able to provide a low bar of customer service, and an even lower bar of internet quality—all at a high price. But they don’t manage the entire global internet: they just tap into bandwidth from the internet backbone at data centers, and build infrastructure from those locations to different towns, neighborhoods, and eventually, individual homes and businesses. Two barriers to entry have helped these monopolies hold onto their power: Laying the physical infrastructure that runs from their primary source of bandwidth all the way to your house, and supplying each house with the hardware they need, is expensive. Starting and managing a traditional ISP requires significant time, human resources, and technical know-how to manage the network manually. Althea networks break down the first barrier by distributing the up-front investment in the hardware required to run the network. Each participant owns the equipment that connects their own home or business. The return on this individual investment is, for all users, better and more reliable internet service—and for users that connect other nodes nearby, the ability to make money too. This individual ownership is made possible because Althea allows each node to automatically buy and sell bandwidth from neighboring nodes, effectively making each node its own ISP. Althea allows communities to cut out the middleman. Althea also addresses the second barrier: the sheer complexity of centralized network management. Althea nodes manage their own connections to their peers, eliminating most network management (although physical installation wires and aiming of antennas is still necessary). This dramatically reduces the workload of the local groups Subnet DAOs, that promote, and support the networks. https://altheamesh.com

  • NBDN: BlockScout an open source block explorer

    Nashville Entrepreneur Center

    This month we'd like to welcome our special guest Andrew Cravenho, project lead of BlockScout! BlockScout is an open source blockchain explorer which provides an easy-to-use interface for users to inspect blocks, transactions, tokens, contracts, and addresses of any EVM (Ethereum Virtual Machine) blockchain. BlockScout will support 6 networks when it’s launched including Ethereum Mainnet, Kovan Testnet, Ropsten Testnet, Ethereum Classic, POA Core, and POA Sokol. Much of the Ethereum community uses a block explorer called Etherscan. While this explorer offers many great tools and user experiences, they’re closed source and centralized. Sidechains, forks, and independent networks don’t have access to these tools that Etherscan offers. This is the reason BlockScout has been created. All EVM chains now have access to many of these same tools. Blockscout is an Elixir application built on the Phoenix web framework, PostgreSQL, and many other open source efforts. The choice of using Elixir was an easy decision with its scalability, concurrency, and fault-tolerance systems. The development of BlockScout is ongoing but here is a list of current features: - Open source development - Realtime events - Smart contract verification - Smart contract querying - Token support (ERC20 and ERC721) - User customization This presentation will demonstrate the capabilities, features, and tools that BlockScout offers to the Ethereum ecosystem. A demonstration will also be provided on how to deploy BlockScout on your own private network customizing your logo, color scheme, and RPC endpoints. Finally, we will discuss how to get involved in the POA Network community, future developments, and other projects that might be of interest to developers interested in contributing to the POA Network initiative.

  • NBDN: Building financial applications on Web3, a Dharma Loan Relayer on Settle.

    Scott Lewis and Roni Davelman will lead a meetup on their startup, the Concourse Open Community, and its new project Settle, open platform for blockchain finance. The Concourse Open Community is known for ConcourseQ, the token due diligence resource, and Dapped, the dapp discovery site. The newest and most ambitious Concourse project is Settle. Settle is a web3 platform that empowers developers to build financial applications with a generous revenue sharing model. This meetup will focus on decentralized finance. More and more startups are getting big funding rounds from top tier VCs to build financial infrastructure, accessible with Web3. What are some of the advantages over traditional finance? What are some of the challenges? Where are the opportunities right now? After an introduction of the Concourse Open Community and Settle, Roni Davelman will lead a live coding session deploying a Dharma relayer to Settle. Dharma is a platform for building borderless lending products using programmable, tokenized debt. Dharma has caught the attention of many in the space for being an innovative protocol taking advantage of the unique capabilities of Ethereum. You will learn a bit about how one vision for a decentralized financial system would work. Minutes: https://www.evernote.com/l/AGtfAfheg_lE1qQqOuCyglVUvYe4iO4v_Oc

  • NBDN: August - Livepeer - A Decentralized Video streaming protocol

    Nashville Entrepreneur Center

    This months special guest is Yondon Fu a software engineer for Livepeer. This exciting technology is being used around the world today and is live in production. Livepeer is regularly used in Livestream blockchain events globally such as the Ethereum Developer calls and has been utilized in many other streaming events. EG: https://github.com/ethereum/pm/issues/50 Livepeer is a decentralized video streaming protocol that empowers developers to build video enabled applications backed by scalable and cost efficient video streaming infrastructure supported by a competitive marketplace of service providers. Today, in order for video content to reach a wide audience such that it can be viewed on a variety of devices under a variety of network conditions, video content is transcoded into various renditions with different bitrates and formats. Video transcoding is an expensive operation and within the traditional video streaming world, developers face the high fees charged by a limited number of large service providers and expensive licenses for closed source proprietary media server software. The Livepeer protocol leverages cryptoeconomic design made possible by Ethereum smart contracts in order to create an economically incentivized network of service providers running open source media server software competing to help users transcode video content. This presentation will provide an overview of the architecture of the Livepeer protocol and describe how video transcoding jobs are created, executed and paid for in the network. Then, the remainder of the presentation will focus on the cryptoeconomic mechanisms that the Livepeer protocol uses in order to incentivize honest and quality participation including inflationary rewards as a coordination mechanism to distribute work across the network, dynamically adjusting inflation targeting a participation rate and probabilistic verification of video transcoding. Finally, they will discuss some of the open areas of research that might be of interest to people interested in contributing and joining the Livepeer community such as Ethereum scalability solutions for Livepeer, gas accounting for video transcoding, and more flexible job negotiation.
