Sharding Middleware to Achieve Elasticity and High Availability in the Cloud
 
01:07:15
To truly embrace the cloud, you must do more than simply deploy existing applications to a virtualized infrastructure: you must think, design, and architect differently. This session examines some of the fundamental and somewhat radical departures in system design when we apply the "sharding paradigm" to traditional middleware. As examples, it discusses how sharding is influencing the way we design enterprise products such as GlassFish, Oracle WebLogic, and Oracle Service Bus, together with the underlying services that may be available to regular developers building enterprise-class systems in the applications in the future.

Greenpeace Shard protest. How it happened. (ft music from Alt-J)
 
04:22
1 skyscraper. 6 women. No permission. http://savethearctic.org Music: "Dissolve Me", generously supplied by Alt-J, supporters of the movement to save the Arctic. At 4:20 in the morning, 11 July 2013, six climbers began a 15 hour climb of Europe's tallest building, the Shard, to send a message to the headquarters of oil giant Shell. This behind-the-scenes film captures the months-long build-up to the climb and the first hair-raising moments when things didn't go to plan. The climb was live-streamed from the activists' helmet cameras in a ground-breaking digital campaign roll-out that represented a "new paradigm", according to leading PR advisor Solitaire Townsend. A live audio commentary overlaid the footage for the whole day -- with Greenpeace presenters interviewing experts and taking comments from as far away as New Zealand (Xena actress Lucy Lawless called in to the show). #Iceclimb trended globally on Twitter and at one point six of the top ten trending topics in the UK were about the protest. In the last 30 years we've lost 75% of the Arctic sea ice volume. And as the ice melts, Shell and other oil companies want to drill there for more oil. Burning that oil only accelerates the melt. It is up to us to stop Shell's dangerous and destructive plans. The climbers: Ali Garrigan, 27 (UK), Liesbeth Deddens, 31 (Netherlands), Sabine Huyghe, 33 (Belgium), Sandra Lamborn, 29 (Sweden), Victoria Henry, 32 (Canada), Wiola Smul, 23 (Poland).

Telegram ICO - Telegram Open Network – TON - 2018
 
01:51
This is a lovely leaked Telegram ICO promotional trailer narrated by Kurzegast voice Steve Taylor. Find all the information on https://telegram.org/ Leaked PDF Whitepaper - https://drive.google.com/file/d/1ucUeKg_NiR8RxNAonb8Q55jZha03WC0O/view No official announcments have been made so far from telegram about an upcoming ICO. Telegram, an app with over 180 Million users and growing 500,000 people daily, will be releasing their own blockchain that can run millions of transactions per second. ( Visa does only 10,000 ) The Telegram Open Network "TON" will also act as an app platform that can host thousands of applications. in 2018, over 200 million people will already be using the TON blockchain. TON The Next Bitcoin?!? Telegram ICO $1.2 Billion About Telegram Open Network TON Blockchain At the core of the platform is the TON Blockchain — a scalable and flexible blockchain architecture5 that consists of a master chain and up to 292 accompanying blockchains. Below are some notable design choices that allow the TON Blockchain to process millions of transactions per second. Infinite Sharding Paradigm To achieve scalability, TON has built-in support for sharding: TON blockchains can automatically split and merge to accommodate changes in load. This means that new blocks are always generated quickly and the absence of long queues helps keep transaction costs low, even if some of the services using the platform become massively popular. Instant Hypercube Routing TON blockchains use smart routing mechanisms to ensure that transactions between any two blockchains will always be processed swiftly, regardless of the size of the system. The time needed to pass information between TON blockchains grows logarithmically with their number, so scaling to even millions of chains will allow them all to communicate at top speed. Proof-of-Stake Approach TON uses a Proof-of-Stake approach in which processing nodes («validators») deposit stakes to guarantee their dependability and reach consensus through a variant of the Byzantine Fault Tolerant protocol. This allows TON to focus the computing power of its nodes on handling transactions and smart contracts, further increasing speed and efficiency. 2-D Distributed Ledgers TON can «grow» new valid blocks on top of any blocks that were proven to be incorrect to avoid unnecessary forks. This self-healing mechanism saves resources and guarantees that valid transactions will not be discarded due to unrelated errors. TON Platform As a multi-blockchain project, TON requires sophisticated network protocols — such as the TON P2P Network used to access the TON blockchains6 — that can be reused to give a significant boost in flexibility to the platform. The following components are scheduled to be released after the TON Blockchain core and will further increase the potential uses of the TON infrastructure. https://www.g2a.com/r/tarantulo - Buy cheap Steam games here that is a place where I buy all my games :) You can even sell you spare games here.

Европейский центральный банк (ЕЦБ) обозначил, что «на форуме G20 в Буэнос-Айресе в марте этого года будет обсуждаться вопрос контроля цифровых валют». О совместных действиях западных стран уже заявили представители Англии, США и других стран. Хотя, руководитель центрального банка Швеции заявила, что нет необходимости в  усилении контроля за цифровыми валютами, они «не отвечают понятию денег». https://cointelegraph.com/news/european-central-bank-expects-crypto-regulation-focus-at-g20-in-march 2 Китайская финансовая ассоциация призывает не участвовать в зарубежных ICO. Они заявили: «Так как во всем мире правительства ужесточают регулирование криптовалют, некоторые зарубежные ICO и торговые платформы также могут столкнуться с риском принудительного закрытия из-за проблем с соблюдением правил. Поэтому инвесторам следует быть осторожными». https://www.coindesk.com/chinese-finance-association-cautions-on-overseas-icos-and-crypto-trading/ 3 Виталик Бутерин заявил на недавней встрече разработчиков что Ethereum еще на один шаг приблизился развертыванию шардинга – технологии, направленной на масштабирование сети.

Stream Scaling in Pravega
 
42:55
Stream processing consists of ingesting and processing continuously generated data, often from end users in web applications or from more challenging settings where devices such as servers and sensors generate events at a high rate. Such scenarios often demand the use of a software stack that is able to scale and accommodate changes to the characteristics of the application. One of the major challenges with processing data streams is adapting to workload variations (e.g., due to daily cycles or the growth of the population of sources). Systems to ingest stream data typically parallelize it by sharding the incoming messages and events according to a routing key. Having the ability to parallelize ingestion is very effective, but future changes to the workload (which are very often unknown beforehand) might make the initial choice for the degree of parallelism inadequate for even short-term spikes. Consequently, the ability to scale by adapting parallelism according to workload while preserving important API properties, such as per-key order, is highly desirable to handle mission-critical workloads. In this presentation, we explain how to accommodate changes to workloads in and with Pravega, an open source stream store built to ingest and serve stream data. Pravega primarily manipulates and stores segments (append-only byte sequences), forming streams by creating and composing segments, which it uses to enable the scaling of streams. Stream scaling in Pravega is automatic and transparent to the application, but such a change to the ingestion volume might also require the application to follow and scale its resources downstream (e.g., the operators of an Apache Flink job) to accommodate the new ingestion volume. Pravega signals such changes to the application so that it can react accordingly. The cooperation between Pravega and the downstream application is crucial for building an effective stream data pipeline.

Lightning, Plasma, Raiden, and State Channels
 
07:58
Blockchains suffer from scaling issues. This is due to the fact that every transaction has to be propagated to all the nodes in the network and after propagation is complete the mining activity to create a block and provide a confirmation. In bitcoin blockchain a confirmation can take about ten minutes. When it comes to the security of a blockchain the number of nodes is directly related to the security of the blockchain, more nodes mean better security. Whereas the performance is indirectly proportional whereby as the number of nodes increases the blockchain starts to slow down as the transactions need to be propagated to more nodes. Transactions Per Second (TPS) for some blockchains are: • Bitcoin Blockchain processes 7 TPS • Ethereum processes 13TPS • Ripple processes 1500 TPS • Visa processes 1700 TPS, if required the system can process up to 56000 TPS Show notes: https://www.securityprivacyrisk.com/lightning-plasma-raiden-and-state-channels/ Links to my social presence:   Facebook Group: https://www.facebook.com/groups/2028470514075912/admin_activities/ Apple Podcast Channel: https://itunes.apple.com/ca/podcast/security-privacy-risk-management-cryptocurrencies-fintech/id1341499853 Google Play Podcast: https://partnerdash.google.com/music/podcasts/portal/u/0#p:id=playpodcast/series&a=2354411696828237 TuneIn Radio: https://tunein.com/radio/Security-Privacy-Risk-Management-Cryptocurrencies-p1095473 YouTube Channel: https://www.youtube.com/channel/UCQtYBTppBxS0WLeCBx33gNQ?sub_confirmation=1 References • Karl Floersch: Plasma Cash and the Ethereum Roadmap • What are state channels? • The Bitcoin Lightning Network Questions - Andreas M.

ZILLIQA NEWS | ZILLIQA COIN PRICE PREDICTION
 
07:17
HELLO THIS VIDEO zilliqa news,zilliqa coin price prediction,zil zilliqa,zil price,zilliqa,zilliqa zil,zil,zil crypto,zilliqa ico review,zilliqa exchange,zilliqa coin price prediction 2018 Nothing will boost an altcoin better than listings on the world’s top exchanges. The relatively unknown altcoin Zilliqa has had a very fortuitous couple of days with listings announced on three major exchanges in Asia. As a result this cryptocurrency has surged 75% over the past week and over 450% on the month. Daily gains are above 30% as South Korea’s two major exchanges announced that they would be listing ZIL. On May 8 the second largest exchange in the world, OKEx announced its listing of Zilliqa which sent the coin skywards throughout the day Its market cap exceeded $1 billion which sent the coin up the charts surpassing the likes of Verge and Lisk. Just a few hours ago Upbit and Bithumb, South Korea’s largest two exchanges, ranked 4th and 6th globally, also announced that they would be listing Zilliqa. In addition to the listing of ZIL, Upbit would also be giving away 2 million tokens to wallets that hold more than 20 as an incentive to boost trade. It had immediate effect and ZIL jumped from $0.15 yesterday to over $0.20 today. Zilliqa uses sharding technology to provide ‘a new smart contract paradigm designed with high parallelism, atomic commits and user-defined security budget’. It boasts thousands of transactions per second claiming that it can support dApps demanding transaction rates beyond the capabilities of today’s blockchains There is a total supply of 12.6 billion ZIL with 7.2 billion currently circulating. Market cap at the time of writing is $1.4 billion and most of the trade volume has been handled by Binance over the past few days. Just as Bytecoin pumped and dumped a few days ago today’s coin of the moment is Zilliqa. Time will tell if momentum can be maintained or whether this altcoin is another flash in the pan. At the moment it appears to be another fancy blockchain project joining the already crowded crypto space. Zilliqa has become one of just 28 cryptocurrencies to boast a market capitalization over $1 billion. According to CoinMarketCap, Zilliqa passed the $1 billion threshold late Monday and is worth nearly $1.2 billion at the time of writing, making it the world's 23rd-most valuable cryptocurrency. The rise coincided with the announcement that Zilliqa is available to trade on OKEx, the third-highest volume cryptocurrency exchange tracked by CoinMarketCap. The coin is also available to trade on Binance, Huobi and Gate.io, among others. The Singapore-based project presents itself as solving the scalability problems endemic to blockchain technology through sharding, an efficiency-boosting technique that predates bitcoin but has yet to prove its viability in big permissionless networks. First introduced last year, the team's white paper claims that "at ethereum's present network size of 30,000 miners, Zilliqa would expect to process about [1,000] times the transaction rates of ethereum." The ethereum network plans to introduce sharding in the future, perhaps undercutting Zilliqa's value proposition. Zilliqa, which is headquartered in Singapore, is a new blockchain protocol that is designed to scale securely in an open, permission-less distributed network. The partnership will involve testing Zilliqa’s blockchain protocol for on-chain high-throughput transactions for the Noorcoin ecosystem. The design of Zilliqa supports thousands of transactions per second while maintaining strong security and decentralization. In contrast, Bitcoin and Ethereum can support only about 3-15 transactions per second today, which is why Noorcoin is interested in testing the application of this platform. "We’ve decided to build on Zilliqa’s platform since it opens up new options that weren’t possible earlier. We aspire to achieve outstanding quality, and to be a pioneer in setting the best practices in the world for the growing blockchain industry. With Zilliqa we believe that we can achieve that goal," said Sofia Koswara, Founder & CEO of Noorcoin. “We are looking forward to working with Noorcoin and applying the Zilliqa blockchain protocol to enable another fast and secure on-chain transaction use case,” said Xinshu Dong, CEO of Zilliqa. ,zilliqa price prediction 2019,zilliqa price prediction 2020,zilliqa price prediciton 2021,zilliqa price prediction,zilliqa coin,zilliqa review,zilliqa coin review,zilliqa price,zilliqa prediction,zilliqa price prediction 2018,zilliqa price 2018,SkrillaKing,CRYPTO PRODUCTIONS disclaimer i am not a financial advisor you should not take my advice as financial advise cryptocurrency market is totally risky and volatility so nothing is guaranteed do your own research lastly all your profits will be yours and all your loses will be yours JOIN OUR COMMUNITY ON INSTAGRAM https://goo.gl/6TiMrJ TWITTER https://goo.gl/BxvwUf

INTERVIEW (English RESPONSES) Cryptocurrencies - Pyramid Scheme, Bubble, or Long-term Investment?
 
44:36
More here: http://samvak.tripod.com/nm017.html Cryptocurrencies represent a major foundational revolution whose full implications are yet to be grasped. They challenge the paradigms underlying both the central banks’ money monopoly and public digital goods. Cryptoassets are digital goods, but they are scarce: they require “mining” and the total number of units in limited. Consequently, cryptoassets such as cryptocurrencies are rivlarous (there is a marginal cost associated with producing additional units) and excludable (access to and ownership of the cryptoasset is restricted). Blockchain technologies are to transactions what TCP/IP is to connections: they offer distributed, redundant, and autonomous self-updating, propagated, time-stamped, linked, irreversible, consensus-driven (polled), and smart (self-executing) electronic ledgers. Blockchain technologies present the first feasible solutions to counterfeiting, security policies, identity management, auditing, real-time transacting, mobile and micropayments, scarcity management, monetizing intangibles, crowdsourcing, record keeping, and a host of other hitherto intractable bottlenecks in business and finance. Blockchain technologies seamlessly interface across private, consortium, and public networks. The risks are as big as the promises and the rewards: from asset bubbles to money laundering, the financing of terrorism, cryptojacking, and threatening the foundations of the financial value chain. These threats are amplified by the recent introduction of exchange-traded bitcoin derivatives (options and futures), ETFs and mutual and hedge funds which invest in cryptoassets, and sovereign cryptocurrencies (e.g. in Russia, Sweden, Venezuela), thereby granting putative future access and price-setting privileges and power to financial institutions and commodifying the underlying assets. The technology used by first generation cryptoassets is slow because transactions are processed serially and with a block size of 1 Mb. Blockchains are far slower than relational databases. Emerging solutions such as sharding, layering, and BaaS (Blockchain as a Service) may compromise the safety of the blockchain and render it hackable. QBit (quantum computing) with a block size of 2 Mb may be the solution. These risks are also attendant upon new approaches to coinage such as minting (instead of mining) and proof of stake (instead of proof of work with a target value). Current software is also buggy. Ethereum, for example, lacks a decimal point (for self-executing scripts). Once blockchains become mainstream, centralized control is likely to render them more hackable. Regrettably, the technology is anarchically fragmented with not a hint of impending standardization. The main concern, though, is the fact that cryptocurrencies, though they do store value as investment vehicles, failed to become accepted means of exchange. In the absence of this crucial function, they are bound to wither and then vanish in a speculative boom and bust. One possible solution would be to link cryptoassets to crowdfunding as its main form of “money”. Cryptocurrencies are actually crowdsourced and the underlying blockchain technology would introduce rigorous fraud control beyond the current rather flimsy peer-review cum peer-pressure mechanisms in place in P2P financing.

#238 Dr. Amrit Kumar & Dr. Ilya Sergey: Scilla – A Formal Verification Oriented Contract Language
 
01:11:30

Creating the languages and software tools to enable ordinary developers to write safe contracts has become an intense research endeavor in the cryptocurrency space. Scilla is a Turing incomplete intermediate level language; inspired from the paradigms of functional programming and formal verification; that makes it easy for smart contract developers to automatically prove statements about smart contract behavior. For example, Scilla could allow a future multi-signature smart contract author to mathematically prove that funds in that contract would always be retrievable by certain addresses (and never get stuck like the Parity incident). The ability to mathematically prove such safety properties of the smart contract has the potential to be an enabling invention prior to widescale use of this technology. In this episode, we are joined by Dr. Amrit Kumar and Dr. Ilya Sergey to discuss Scilla, the smart contract language of the upcoming Zilliqa blockchain. In a previous episode, we've already covered the vision and technical approach of Zilliqa to solve the transaction scalability problem of permissionless blockchains. This episode focuses specifically on their smart contract language development efforts. Topics discussed in this episode: - Updated on Zilliqa's progress since our last episode - The technology of mechanised proofs - Dr. Ilya Serger's effort to mechanically prove safety properties of a blockchain consensus network - Aims of the Scilla language - Future capabilities enabled by the Scilla language - Developer experience and perspective using formal verification tools - How Scilla compares to Michelson, Tezos' approach to smart contract languages with a similar end goal - Current state of development of Scilla, and next milestones Links mentioned in this episode: - Our previous episode on the Zilliqa platform: https://www.youtube.com/watch?v=Dppk6n9LHBk - Ilya Sergey's paper on mechanising blockchain consensus: http://ilyasergey.net/papers/toychain-accepted.pdf - Scilla whitepaper: https://arxiv.org/abs/1801.00687 - Michelson, Tezos platform's smart contract language: https://www.michelson-lang.com/ - Zilliqa blog for updates on platform development: https://blog.zilliqa.com/ - Coq, a formal proof management system: https://coq.inria.fr/ Sponsors: - Gnosis X: Build a revolutionary prediction market dApp on Gnosis & win up to $100,000 in GNO tokens - http://epicenter.tv/gnosisx This episode is also available on : - Epicenter.tv: https://epicenter.tv/238 - YouTube: http://youtu.be/tPqnK2iNGZo - Souncloud: http://soundcloud.com/epicenterbitcoin/eb-238 Watch or listen, Epicenter is available wherever you get your podcasts.

In a future in which entire industries and economies rely on distributed technologies, it is unclear how blockchain networks will support massive amounts of data, and exchange transactions in a trusted way. Peter Czaban, co-founder of Polkadot, joins us as we dive deep into the Polkadot Network. Polkadot is a heterogeneous multi-chain network, consisting of many connected chains (or parachains), all of which have their own set of features and characteristics. Transactions flow across chains, while Polkadot ensures the global security and consensus of the network, forming an ‘Internet of Blockchain networks’. Scalability is achieved through the parallel processing of transactions on the different parachains. Topics discussed in this episode: - Peter's background and his role at Parity technologies - What is the Polkadot project and what problems it is addressing - How Polkadot handles the issue of scaling - The different components of the Polkadot Network - The various players in the network - The consensus model used in Polkadot - The types of applications Polkadot would enable - The Web3 Foundation and its goals Links mentioned in this episode: - Polkadot Website: https://polkadot.io - Polkadot Pre-Sale Website: https://polkadot.network - Polkadot Community Chat: https://riot.im/app/#/room/#polkadot-trenches:matrix.org - Aura Consensus: https://github.com/paritytech/parity/wiki/Aura Sponsors: - Ledger: Industry standard security meets convenience and usability with the Nano S - http://epicenter.tv/ledger - Shapeshift: Buy and sell alt coins instantly and securely without a centralized exchange - http://epicenter.tv/shapeshift Watch or listen, Epicenter is available wherever you get your podcasts.
