In the past years cryptocurrency blockchains (like Bitcoin and Namecoin) have seen significant adoption with the promise of using such blockchains as general-purpose databases and/or key-value stores. Cryptocurrency blockchains provide a zero-trust infrastructure, where users can securely store and retrieve information while providing security guarantees that only the owner of a particular private-key can write/modify the data. In theory, many decentralized services/application can be built using cryptocurrency blockchains as key-value stores. However, the area is relatively new and rapidly evolving with little production experience/data available to guide design tradeoffs. In this talk, we describe our experience of operating a large real-world deployment of a decentralized naming service, called Openname, built on top of a cryptocurrency blockchain (Namecoin). We present the various challenges that we had to overcome while registering/updating over 30,000 users on the blockchain and discuss how our experience informed the design of a new blockchain-based key-value store, called Blockstore. All of our code is available as open-source at http://github.com/openname.

Support the show, consider donating: 18wPYDA78Erbhjfskq1bAH87T5oiWejmha (http://bit.ly/1kmAhQv) One of the concerns confronting the Bitcoin community is that of scaling the transaction throughput rate: How do we go from the current rate of approx. 5 transactions per second to a thousand times that? In this episode, we talk to Emin Gun Sirer and Ittay Eyal from Cornell University regarding Bitcoin NG; a next generation Bitcoin blockchain design that addresses some protocol based limitations preventing Bitcoin from increasing transaction throughput. Their proposal also enables fast (initial) transaction confirmations on the order of 10-20 seconds. Topics covered include: - Metrics to measure the security and fairness properties of Nakamoto consensus as implemented in Bitcoin. - A network emulation of Bitcoin designed by their team to study properties of Bitcoin network. - Technical design of Bitcoin NG - Concerns with Bitcoin NG - Impact of Bitcoin NG on various stakeholders if it is adopted in the main Bitcoin network.

PyData Berlin 2016 This talk describes BigchainDB. BigchainDB fills a gap in the decentralization ecosystem: a decentralized database, at scale. It has big-data performance levels, a querying system, and a permissioning system that supports public and private versions. It's complementary to decentralized processing platforms like Ethereum, and decentralized file systems like IPFS. BigchainDB is written in Python. This talk describes BigchainDB. BigchainDB fills a gap in the decentralization ecosystem: a decentralized database, at scale. It points to performance of 1 million writes per second throughput, storing petabytes of data, and sub-second latency. The BigchainDB design starts with a distributed database (DB), and through a set of innovations adds blockchain characteristics: decentralized control, immutability, and creation & movement of digital assets. BigchainDB inherits characteristics of modern distributed databases: linear scaling in throughput and capacity with the number of nodes, a full-featured NoSQL query language, efficient querying, and permissioning. Being built on an existing distributed DB, it also inherits enterprise-hardened code for most of its codebase. Scalable capacity means that legally binding con- tracts and certificates may be stored directly on the blockchain database. The permissioning system enables configurations ranging from private enterprise blockchain databases to open, public blockchain databases. BigchainDB is complementary to decentralized processing platforms like Ethereum, and decentralized file systems like InterPlanetary File System (IPFS). This talk describes technology perspectives that led to the BigchainDB design: traditional blockchains, distributed databases, and a case study of the domain name system (DNS). We introduce a concept called blockchain pipelining, which is key to scalability when adding blockchainlike characteristics to the distributed DB. We present a thorough description of BigchainDB, a detailed analysis of latency, and experimental results. The talk concludes with a description of use cases.

Centralized applications, while trusted and widely used, implicitly carry centralized weaknesses. This is seen with companies like Facebook and Uber for example. Meanwhile decentralized applications that provide scalable solutions for data privacy are useless. The solutions to data privacy do not exist on or off the Blockchain, yet.

James Lovejoy, spoke about Lit, the MIT Digital Currency Initiative's Lightning Network Implementation. "James discussed his experiences applying Lit (the DCI's Lightning Network implementation) to real-world use cases, focusing on how it might work in practice when put into the hands of users. Given that there are now multiple possible architectures and specifications for payment channel networks (Interledger, BOLT, Lit, Raiden), James covered some of the major differences between the systems, and how Lit aims to solve some of the challenges moving forward. James started mining Bitcoin in 2013 and was captured by the prospect of a trustless, permissionless financial system. Since starting at the DCI two years ago, James has been working primarily on Cryptokernel; a distributed ledger development toolkit as well as Lightning Network related projects. James works on the Digital Fiat Currency project, aiming to use Cryptokernel to demonstrate a workable fiat currency design based on distributed ledger technology. James is also the lead developer of Vertcoin, which he has been since late 2014."

Jehan Tremback spoke about Althea (http://altheamesh.com/), a set of low-level mesh networking protocols designed to replace ISPs with micropayments. "Maidsafe, IPFS, and many others seek to create a 'decentralized internet' which will reduce costs and free consumers from corporate and government control. However, none of these projects deal with the actual network infrastructure that delivers data packets across the world. Althea is a set of low-level mesh networking protocols allowing backbone and last-mile routers to pay each other in Bitcoin (or conventional currencies), per-packet, eliminating the role of corporate and government ISPs. This talk will focus on Universal Payment Channels, the micropayments standard enabling the network. UPC can be used for more than just mesh networks, it is useful for any application which requires scalable p2p micropayments in any currency and across currencies."

You may be familiar with our series of interviews that take you inside Atlassian and show you how we make software. But the vision for Atlassian Tech TV has always been larger than that. For something quite different, this episode I take you to South By SouthWest, a huge festival that takes place in Austin, Texas each year, with over 72,000 people attending. I was fortunate enough to be accepted to speak on a technology topic that is not only near to my heart, but also something I think is a pivotal piece of 21st century software infrastructure that I see as the next application platform for developers. I pitched this talk as an advanced topic for software developers, but as it happens there were also a lot of newbies who came to see what I had to say so I tried my best to make my material more accessible to a broader audience. You might have heard of Bitcoin, and if you've read beyond the headlines you may also have heard of the blockchain. If you haven't read beyond the headlines and you're a software developer, you need to watch this. It's a long episode, as it covers a lot of material. So this time on Atlassian Tech TV, I present in its entirety, my talk on Bitcoin & Blockchains as the next app platform, recorded live at SXSW Interactive. Talk Description: Bitcoin and its blockchain are more than a currency and payment network. Bundled with peer-to-peer crypto toolchains and secure execution engines, blockchains enable novel distributed apps. Internet's missing piece of 25 years. Never mind FinTech Startups, any app can use smart contracts, digital identity, content integrity, secure messaging and true ecommerce all with no trusted third-party. Replacing trust with proof, our apps are more independent of mega-platform providers. Crypto-era stacks monetize natively, scale without provisioning, uphold privacy, stop data corruption, secure execution and resist tampering. Examples from: Ethereum, BitShares, MaidSafe, Counterparty.

Today, each of us is pulled in a thousand different directions every day. We are pinged constantly by applications whose business models depend upon getting us addicted to their services so that we spend more of our time with them. But this is a consequence of how web applications (and even most "blockchain" applications) are built today. If the internet revolved around people instead of companies, what might that make possible? Holochain is a new pattern for building not just truly distributed applications but goes beyond that to foster empowering and adaptive software ecosystems. About Speaker Matthew Schutte, Director of Communications, Holo.host Matthew works on Holochain, a new way of building and running applications that puts people in control of their digital lives. Holochain enables a new pattern of communication that empowers individuals, fosters trust and helps build thriving communities. Inspired by the design patterns of natural living systems, Holochain applications are faster, more scalable and 10,000 times cheaper than blockchain approaches. Matthew is a graduate of UC Berkeley School of Law and sometimes surfs 10 - 15 meter waves at the world famous Mavericks near his home in San Francisco.

An exploration of Developer Experience (DevX). We know there are many challenges around User Experience (UX) for end-users who are trying to use decentralized applications but what about the developers who build those applications? Their experience is often under-appreciated. In this meetup, we dug deeper into what developer experience (DevX) really means, the state of it on today's platforms and how we can improve it in the future. We surveyed the landscape and tore down a couple of existing platforms. Following the talk by Erik Trautman, our Head of Operations, we moved to a panel discussion with developers of apps on multiple different platforms about the pros and cons of development on each platform. About the Speaker and Host: Erik Trautman leads operations at NEAR Protocol, which is a scalable mobile-first blockchain. He has a long history in technical education: he started in market analysis on Wall Street in 2007, created the popular Odin Project in 2012 and ran Viking Education as its CEO until its acquisition in 2017. Panelists: 1) Viktor Radchenko, Founder of Trust Wallet (Acquired by Binance). 2) Amhed Herrera is a Software Engineer from the Dominican Republic, where he founded two startups before moving to the US. He's been working as a full-stack software engineer since 2010, and on smart contracts and dApps since 2018. Recently joined the Harbor.com team where they're working on tokenizing securities on the blockchain. 3) Jehan Tremback is CEO of Althea (althea.org), working on a system that makes it easy for communities to set up networks which are faster and cheaper than the existing ISP monopolies, by enabling routers to pay each other for bandwidth, using cryptocurrency. He has years of experience in the Ethereum ecosystem and will be speaking about the ins and outs of building Dapps such as payment channels, voting systems, and DAOs. 4) Chris Li is the founder of Forge Labs, a decentralized blockchain accelerator headquartered in San Francisco. He recently led the team to build a game Dapp on EOS and became No.8 in daily DAU. Before, he was director of engineering at Bodhi Prediction Market, in charge of smart contract and backend development. Before blockchain, he was a serial entrepreneur and senior engineer at Microsoft, where he worked on Exchange, a complex distributed system for 4 years. **About the Blockchain Onramp Series** Blockchain Onramp is a series of events covering the full spectrum of knowledge necessary to operate effectively within the blockchain ecosystem as a designer, developer or product person. After participating in these events, you should be able to take your functional expertise in any of these areas and apply them to blockchain projects.

Want an exclusive Quarkchain update? BlockchainBrad chats with Qi Zhou (Founder). Wanna talk about upgrades, innovations and developments on this permissionless blockchain architecture? Well here's the July updates. Quarkchain: A High-Capacity Peer-to-Peer Transactional System Quarkchain Features: Two-layered blockchains The QuarkChain consists of two layers of blockchains. We apply elastic sharding blockchains (shards) as the first layer, and a root blockchain that confirms the blocks from the shards as the second layer. Cross-shard transactions Cross-shard transactions can be issued at any time, and confirmed in minutes. The throughput of cross-shard transactions increases linearly as the number of shards increases. Market driven collaborative mining We designed a game theoretic framework for incentives, where hash powers are incentivized to distribute evenly among shards. There are at least 50% of overall hash power allocated to the root chain to prevent double spending attack. Simple account management There is only one account needed for all shards. All cryptocurrencies from different shards are stored in one smart wallet. Horizontal scalability Because a super-full node can be extremely expensive when TPS goes high, we allow multiple honest nodes forming a cluster running as a super-full node.

Arthur Brock devotes his time to projects that he believes support and accelerate the harmonious evolution of humanity, most recently building targeted currencies to shape the social dynamics of an emerging post-industrial economy. He’s created more than a hundred designs for multi-currency systems, and his current project, Holochain, provides an alternative to the blockchain for building and running fully peer to peer distributed applications. Art recently led a series of Holochain workshops in Austin, and took some time for a couple of interviews with our Plutopia correspondents, Benjamin Bradley and Tom Brown.

A Proof of Stake mechanism consists of a distributed consensus protocol and a cryptoeconomic system of incentives and punishments. While many are familiar with Tendermint consensus, this talk will delve into the decisions and tradeoffs that went into the cryptoeconomic design of the Cosmos Hub in order to make a secure and decentralized Proof of Stake blockchain.

This lecture is about implementing Byzantine fault tolerant state machine replication. A Byzantine faulty replica can behave arbitrarily, for example, it may be controlled by an attacker, whereas algorithms like Paxos assume that faulty replicas fail by stopping. Byzantine fault tolerant state machine replication works correctly if less than a third of the replicas are faulty. The lecture starts by discussing assumptions in replication algorithms and how they can be invalidated by an attacker. Then it describes the Castro-Liskov algorithm, explains how it works, and presents a number of important optimizations. Next it discusses implementation issues including a methodology for reusing existing code to implement replicated state machines, and a Byzantine fault tolerant replicated file system built using this methodology. The performance of this implementation is discussed next followed by a brief discussion of other work in Byzantine fault tolerance.

In this presentation, Benedikt Bünz will give a brief technical introduction to cryptocurrencies and will touch on a few research problems related to improving the scalability and privacy of cryptocurrencies. Bünz is a researcher interested in applied cryptography, especially as it relates to cryptocurrencies. Cryptography is the science of secure communication which not only underlies the security of cryptocurrencies, but the internet as a whole. He is a second-year PhD candidate in computer science at Stanford University, where he is advised by Dan Boneh. His work focuses on enhancing the privacy, usability and security of protocols that are related to blockchains. His research includes work on automatic and privacy-preserving auditing of exchanges, making cryptocurrency transactions confidential but still verifiable, as well as developing publicly verifiable lotteries and improving the security and efficiency of mobile cryptocurrency clients.

Support the show, consider donating: 36QwTNb3fmpRwAVkTEf2f8mYsWVsxEffyS (http://bit.ly/1A4aX3f) Bitcoin's approach to solving the double spending problem is to make a collusion and attack on the network prohibitively expensive. One of the main factors that will determine Bitcoin's chance of survival in the long-term is whether the behavior that maximizes the profits of miners contributes to or sabotages the health of the network. The game theory that determines this is complex and our understanding of it still incomplete. But research is increasing and two people who have been at the forefront of this work are Emin Gün Sirer, a professor in computer science at Cornell University, and Ittay Eyal, a post-doc at the same department. They joined us for a fascinating discussion of their work on 'selfish mining', the incetive structure that underlies Bitcoin and their recent positive conclusions from the Miner's Dilemma. Topics covered included: - Emin Gün Sirer's early interest in cryptocurrencies and work on a cryptocurrency to incentivize bittorrent users in 2004 - What selfish mining is and how miners could profit from withholding blocks - How an attacker would execute a selfish mining attack - Why the miner's dilemma implies that the equilibrium might be small mining pools - Why the lack of security of clients and servers is holding back adoption Links mentioned in this episode: - Selfish Mining paper (PDF): http://bit.ly/1DsCgEK - Miner's Dilemma blog post: http://bit.ly/1EcdbSe - Miner's Dilemma paper (PDF): http://bit.ly/1djBsgj - Hacking, Distributed: http://bit.ly/1A4YTyJ - Meni Rosenfeld's paper on mining pool reward systems (PDF): http://bit.ly/1djBFQL Sponsors: - Buy and sell alt coins instantly with http://ShapeShift.io Show notes: http://epicenterbitcoin.com/podcast/076 SoundCloud: http://soundcloud.com/epicenterbitcoin/eb-076 Epicenter Bitcoin is hosted by Brian Fabian Crain & Sébastien Couture. - Visit our website: http://epicenterbitcoin.com - Subscribe to our newsletter: http://epicenterbitcoin.com/newsletter - Twitter: http://twitter.com/epicenterbtc

-Visit our Website: http://tomochain.com The TomoChain blockchain is produced and maintained by a set of 150 masternodes in a consistent manner through the TomoChain consensus protocol. Masternodes which work hard in the system to create and verify blocks will be incentivized with $TOMO. Furthermore, coin holders who vote for these incentivized masternodes will also receive $TOMO in proportion to the amount of $TOMO they have invested via ballots. Tomochain engineers take responsibility to design that fair, explicit, automated and accountable reward mechanism.
