EB103 – Emin Gün Sirer & Ittay Eyal: Bitcoin-NG, Scientists Versus The Church
 
01:09:30
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.

Trent McConaghy  - BigchainDB : a Scalable Blockchain Database, in Python
 
43:20
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.

EB113 – Jae Kwon, Dustin Byington & Ethan Buchman: Tendermint - Private Modularized Blockchains
 
01:18:37
Support the show, consider donating: 15zDNoYpwY5MF76vZxGyKJ7ppdSBrNUotP (http://bit.ly/1Pt2zpa) As blockchain technologies mature, new protocol specifications are emerging, which take unique approaches to software design and how consensus is achieved. We have talked about Multchain and OpenChain in the past, but Tendermint promises to be a viable solution for many permissioned blockchain use cases. It’s design is modular, meaning that the application layer (smart contract) and the consensus layer are completely independent. This provides added flexibility and allows for business logic to be written in practically any programming language. In addition, its unique approach to consensus, a round-robin Proof-of-Skate algorithm, is much better suited for permissioned blockchain scenarios than Proof-of-Work. Meher and Sebastien talk to Tendermint co-founders, Jae Kwon, Dustin Byington and Ethan Buchman, about this promising new blockchain protocol and how it is different from other projects we’ve seen so far. Topics covered in this episode include: - How Tendermint came to be and how it has evolved since its creation - Smart contract programming and the Tendermint Socket Protocol (TMSP) - How Tendermint makes use of the Ethereum Virtual Machine (EVM) - Tendermint’s approach to PoS consensus and its scalability benefits - Use case for permissioned and public blockchains - Future plans and business models Links mentioned in this episode: - Tendermint: http://tendermint.com/ - Tendermint for fast settlements: http://tendermint.com/posts/tendermint-for-fast-settlement/ - Tendermint vs PBFT: http://tendermint.com/posts/tendermint-vs-pbft/ - Tendermint specification: https://github.com/tendermint/tendermint/wiki Sponsors: - Ledger Nano: Smart card security for your Bitcoins - Get 10% off your first order when you use the code EPICENTER at http://ledgerwallet.com Show notes: http://epicenterbitcoin.com/podcast/113 SoundCloud: http://soundcloud.com/epicenterbitcoin/eb-113 Epicenter Bitcoin is hosted by Brian Fabian Crain, Sébastien Couture & Meher Roy. - Visit our website: http://epicenterbitcoin.com - Subscribe to our newsletter: http://epicenterbitcoin.com/newsletter - Twitter: http://twitter.com/epicenterbtc

Experiences with Scaling Blockchain-based Data Stores
 
01:19:27
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.

Practical Byzantine Fault Tolerance
 
01:50:10
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.

SF Bitcoin Devs: Althea—Incentivized Mesh Networking
 
01:00:56
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."

IOHK | Cardano development techniques, with Duncan Coutts, PhD
 
59:24
Cardano is being developed with the aim of making it high assurance software. This is code that is rigorously developed using certain techniques to ensure it is bug free and fit to carry huge amounts of value safely, something which is currently missing in the cryptocurrency area. In this talk, Dr Duncan Coutts, IOHK’s Director of Engineering, explains a mathematical technique being used to specify and test new components of Cardano’s software. Benefits of this approach include reducing accidental complexity in the code, and a simpler specification leads to simpler implementation, and easier testing that can be conducted comprehensively. There is no other project that has ever been built to these parameters, combining peer reviewed cryptographic research with an implementation in highly secure Haskell code. This is not the copy and paste code seen in so many other blockchains. Instead, Cardano was designed with input from a large global team including leading experts and professors in the fields of computer programming languages, network design and cryptography. We are extremely proud of Cardano, which required a months-long meticulous and painstaking development process by our talented engineers. Duncan has more than 15 years' programming experience with Haskell and is a well-known member of the Haskell community. He helps maintain several popular libraries and tools including Cabal and ByteString. He has several years' experience in packaging the Haskell toolchain and took a leading role in establishing the Haskell Platform. He holds a first-class degree in Computation and a D.Phil in Computer Science, both from Oxford University. He has published papers at international conferences, including ICFP. His research focus is on generating high performance code from idiomatic high-level Haskell code. This included co-authoring the ByteString and Binary libraries and work on stream fusion for lists. He has five years' experience teaching computer science, including four years spent teaching Haskell to mature students at graduate level. -- See more at: https://iohk.io Get our latest news updates: https://iohk.io/blog/ Meet the team: https://iohk.io/team/ Learn about our projects: https://iohk.io/projects/cardano/ Read our papers: http://iohk.link/paper-ouroboros Visit our library: https://iohk.io/research/library/ In the press: https://iohk.io/press/ Work with us: https://iohk.io/careers/ See more on Cardano: https://iohk.io/projects/cardano/ -- The Cardano PortfolioThe Cardano HubThe source for all things Cardanohttps://www.cardanohub.org/en/home/ Cardano Blockchain Explorer An open source block explorer for the Cardano project https://cardanoexplorer.com Cardano Documentation Full technical documentation of the project https://cardanodocs.com Cardano Roadmap Development path of the Cardano project https://cardanoroadmap.com Why Cardano The philosophy behind the project https://whycardano.com Daedalus Platform Open source platform https://daedaluswallet.io The Cardano Foundation Supervisory and educational body for the Cardano Protocol https://cardanofoundation.org Cardano Foundation YouTube All the latest videos & tutorials https://www.youtube.com/channel/UCbQ9...

Smart Contracts and Formal Verification with Z3 with Pact
 
30:52
Stuart Popejoy C◦mp◦se :: Conference http://www.composeconference.org/2017/ May 19, 2017 We present Pact, a new open-source language for authoring smart contracts, built in Haskell. Smart contract languages like Ethereum’s Solidity have taken a maximalist approach to functionality, in no small part because the slow execution speed of public blockchains emphasizes “feature-rich” transactions that compose multiple invariants into a single transaction. Resulting logic is complex, brittle, and often incorrect. With Pact, a high-performance blockchain ensures that transactions can closely model business invariants, and “fail fast” on invalid cases or retry scenarios. Logic is constrained to Turing-incomplete (terminating) execution and single-assignment (immutable) variables. We discuss the unique hybrid of strict OLTP workload and limited key-value querying needed for blockchain applications, and how this informs Pact’s database model. We also discuss the influence of Bitcoin scripts on Pact’s design as well as its integration of public-key authorization schemes. We demonstrate various Pact smart contracts running both in a standalone interpreter as well as in the ScalableBFT blockchain. Finally, we give a demo of static analysis and verification using the Z3 theorem prover, and show the new development environment with a sample application.

Bitcoin and Blockchains as Next App Platform SXSW BlockZombie Chris Mountford
 
01:08:53
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.

IOHK | Cardano whiteboard; Sidechains, Dionysis Zindros.
 
54:25
The idea behind sidechains is that they will allow multiple blockchains to work with one another, as opposed to traditional cryptocurrencies where each blockchain is independent. As such, sidechains are a key component of third generation blockchains in that they enable interoperability. An asset on one blockchain would be able to be moved to another and back without going through a counterparty. Sidechains are being developed for use in Cardano, a third generation blockchain being designed and built by IOHK. Blockchain protocols such as bitcoin provide decentralized consensus mechanisms based on proof-of-work (PoW). In this work we introduce and instantiate a new primitive for blockchain protocols called Noninteractive-Proofs-of-Proof-of-Work (NIPoPoWs) which can be adapted into existing proof-of-work-based cryptocurrencies. Unlike a traditional blockchain client which must verify the entire linearly-growing chain of PoWs, clients based on NIPoPoWs require resources only logarithmic in the length of the blockchain. NIPoPoWs solve two important open questions for PoW based consensus protocols. Specifically the problem of constructing efficient transaction verification clients, sometimes called “simple payment verification” or SPV, and the problem of constructing efficient sidechain proofs. We provide a formal model for NIPoPoWs. We prove our construction is secure in the backbone model and show that the communication is succinct in size. We provide simulations and experimental data to measure concrete communication efficiency and security. Finally, we provide two ways that our NIPoPoWs can be adopted by existing blockchain protocols, first via a soft fork, and second via a new update mechanism that we term a “velvet fork” and enables to harness some of the performance benefits of NIPoPoWs even with a minority upgrade. -- Dionysis is a PhD student in cryptography and blockchain technologies at the University of Athens, working under professor Aggelos Kiayias. His research interests include blockchain foundations, provable security of the permissionless consensus layer, decentralized trust, and compression security. He has published and presented at world-class conferences such as Black Hat, Financial Crypto, Real World Crypto, FOSDEM, BSides, ECESCON, FOSSCOMM. He is the co-founder of OpenBazaar, the first cryptocurrency-based anonymous decentralized marketplace. Some of his important contributions to the field include Rupture, a compression attack framework; and Trust is Risk, the first Sybil-resilient decentralized trust network.
