      "body": "“World’s first decentralized big data and machine learning network, powered by a computing-centric blockchain”\n\nA big claim – but an exciting one – so lets take a look insode this project to see what it’s all about.\n\nFirstly, what is big data?\nBig data is data sets that are so big and complex that traditional data-processing application software are inadequate to deal with them. Big data challenges include capturing data, data storage, data analysis, search, sharing, transfer, visualization, querying, updating, information privacy and data source. There are a number of concepts associated with big data: originally there were 3 concepts volume, variety, velocity.[2] Other concepts later attributed with big data are veracity (i.e., how much noise is in the data) [3] and value.[4]\n\nBig data can be described by the following characteristics: \nVolume\nThe quantity of generated and stored data. The size of the data determines the value and potential insight, and whether it can be considered big data or not.\nVariety\nThe type and nature of the data. This helps people who analyze it to effectively use the resulting insight. Big data draws from text, images, audio, video; plus it completes missing pieces through data fusion.\nVelocity\nIn this context, the speed at which the data is generated and processed to meet the demands and challenges that lie in the path of growth and development. Big data is often available in real-time.\nVeracity\nThe data quality of captured data can vary greatly, affecting the accurate analysis\n\nFactory work and Cyber-physical systems may have a 6C system:\n•\tConnection (sensor and networks)\n•\tCloud (computing and data on demand)\n•\tCyber (model and memory)\n•\tContent/context (meaning and correlation)\n•\tCommunity (sharing and collaboration)\n•\tCustomization (personalization and value)\nData must be processed with advanced tools (analytics and algorithms) to reveal meaningful information. For example, to manage a factory one must consider both visible and invisible issues with various components. Information generation algorithms must detect and address invisible issues such as machine degradation, component wear, etc. on the factory floor\nArchitecture\nBig data repositories have existed in many forms, often built by corporations with a special need. Commercial vendors historically offered parallel database management systems for big data beginning in the 1990s. For many years, WinterCorp published a largest database report.\nTeradata Corporation in 1984 marketed the parallel processing DBC 1012 system. Teradata systems were the first to store and analyze 1 terabyte of data in 1992. Hard disk drives were 2.5 GB in 1991 so the definition of big data continuously evolves according to Kryder's Law. Teradata installed the first petabyte class RDBMS based system in 2007. As of 2017, there are a few dozen petabyte class Teradata relational databases installed, the largest of which exceeds 50 PB. Systems up until 2008 were 100% structured relational data. Since then, Teradata has added unstructured data types including XML, JSON, and Avro.\nIn 2000, Seisint Inc. (now LexisNexis Group) developed a C++-based distributed file-sharing framework for data storage and query. The system stores and distributes structured, semi-structured, and unstructured data across multiple servers. Users can build queries in a C++ dialect called ECL. ECL uses an \"apply schema on read\" method to infer the structure of stored data when it is queried, instead of when it is stored. In 2004, LexisNexis acquired Seisint Inc. and in 2008 acquired ChoicePoint, Inc. and their high-speed parallel processing platform. The two platforms were merged into HPCC (or High-Performance Computing Cluster) Systems and in 2011, HPCC was open-sourced under the Apache v2.0 License. Quantcast File System was available about the same time.\nCERN and other physics experiments have collected big data sets for many decades, usually analyzed via high performance computing (supercomputers) rather than the commodity map-reduce architectures usually meant by the current \"big data\" movement.\nIn 2004, Google published a paper on a process called MapReduce that uses a similar architecture. The MapReduce concept provides a parallel processing model, and an associated implementation was released to process huge amounts of data. With MapReduce, queries are split and distributed across parallel nodes and processed in parallel (the Map step). The results are then gathered and delivered (the Reduce step). The framework was very successful,] so others wanted to replicate the algorithm. Therefore, an implementation of the MapReduce framework was adopted by an Apache open-source project named Hadoop. Apache Spark was developed in 2012 in response to limitations in the MapReduce paradigm, as it adds the ability to set up many operations (not just map followed by reduce).\nMIKE2.0 is an open approach to information management that acknowledges the need for revisions due to big data implications identified in an article titled \"Big Data Solution Offering\". The methodology addresses handling big data in terms of useful permutations of data sources, complexity in interrelationships, and difficulty in deleting (or modifying) individual records.\n2012 studies showed that a multiple-layer architecture is one option to address the issues that big data presents. A distributed parallel architecture distributes data across multiple servers; these parallel execution environments can dramatically improve data processing speeds. This type of architecture inserts data into a parallel DBMS, which implements the use of MapReduce and Hadoop frameworks. This type of framework looks to make the processing power transparent to the end user by using a front-end application server\nBig data analytics for manufacturing applications is marketed as a 5C architecture (connection, conversion, cyber, cognition, and configuration).[51]\nThe data lake allows an organization to shift its focus from centralized control to a shared model to respond to the changing dynamics of information management. This enables quick segregation of data into the data lake, thereby reducing the overhead time\n\nApplications:\n•\t1 Government\n•\t2 International development\n•\t3 Manufacturing\n•\t4 Healthcare\n•\t5 Education\n•\t6 Media\n•\t7 Internet of Things (IoT)\n•\t8 Information Technology\n\nRight so enough of the technical stuff – let’s focus on DX Chain – what is the pain point that it is trying to solve and why does it need the blockchain?\nFirstly it is obvious to say that the blockchain is the best place for securing big data that is immutable and protected from interference – but how do DX Chain propose to solve this on the blockchain and how scalable will it be?\nDX Exchange aims to create a big data and machine learning blockchain. The project uses chains on chain architecture, which includes one master chain into side chains to augment data mining algorithms and that's built on top of its ecosystem. So it's a blockchain ICO.\nLets take a look at some of their material:\n\nNowadays, only large corporates have the capability to run big data tasks and monopolize the data-related services. For individuals and small organizations, it is costly to get data storage services and difficult to acquire data sources. Even worse, the privacy and data security risks are taken by everyone, no matter if you are able to get any rational reward from data services.\nThere are some blockchain-based platforms designed to provide supercomputer services, however there are no existing solutions in the market to provide decentralized parallel computing environment that supports big data and machine learning.\nTherefore, DxChain will be the real game changer in the market.\n\n![](https://cdn.steemitimages.com/DQmXHRmH8txMVBGcpAiho5RjKr6coy52pyEve2RTvn3zA4G/image.png)\n\n![](https://cdn.steemitimages.com/DQmTShDRRXKFHw31RZNrFfAiAPVsexhuRBfHf1ih3P8ai7r/image.png)\n\nBlockchain, one of the most ingenious technological inventions in recent years, has many important and innovative characteristics, such as decentralization and immutability. Unfortunately, today’s popular consensus-based protocol still uses huge amount of computational power to maintain the blockchain itself, and cannot provide useful work for the community. Nowadays, people can use Bitcoin and Ethereum to buy something and use hyperledger fabric to trace the flow of a product. However, there are few real applications of blockchain besides financial transactions and tracking assets in a supply chain. That is to say, blockchain did not fundamentally change the way people are using internet.\nDxChain designs a platform to solve computation of big data in a decentralized environment. Consequently, people can use DxChain as a data market to trade data, and create applications on DxChain to meet various needs, including business operation and businesses intelligence. Therefore, by applying blockchain to data storage and computation, DxChain will change the fundamental meaning of the internet.\n\nOk so this really is a novel idea and looking at their claims it really is an innovation.\nSo – do they have the team to pull this off? Let’s take a look. \n\n![](https://cdn.steemitimages.com/DQmVnKcNfFQ1r9a6u1aY1i5HriEQNnZEfqJnEFYAMsmf1of/image.png)\n\nIndeed, this is certainly world-class team. There is a strong team based in San Francisco. Ken, who is a founder of Block VC. For the co-founder, we have Alan Jiang who worked at Nokia for 4 years, he's currently the CEO of Trust Look which develops AI-based security products. And then we have the second co-founder Mr. Wei Wan, who worked as a blockchain scientist at AT&T for 1.5 years.\n\n![](https://cdn.steemitimages.com/DQmboxW1Kq4Q4gJTvR5i4BD4tqCcvgzsH1mXHfyGEFByyhE/image.png) \n\nToken Sale details and metrics:\nFull details regarding the token sale can be round at https://www.dxchain.com/static/assets/docs/DxChain-token-sale-announcement.pdf\n\nIn colculision I am very excited about what DX Chain has to offer and I will be certainly be making an investment.\nPlease feel free to comment below.\n\nRegards,\nCC.\n\nOther links:\nhttps://t.me/dxchainchannel\nhttps://t.me/dxchain1\nhttps://t.me/dxchain\nhttps://t.me/DxChainGroup_CN\nhttps://medium.com/dxchainnetwork\nhttp://www.dxchain.com/\nhttps://www.youtube.com/c/dxchain\n\nhttps://www.youtube.com/watch?v=LzGT8trLOr8 \n\nMy referral link: tg://resolve?domain=DxChainBot&start=efy0f7-efy0f7  \nhttps://www.dxchain.com/",

      "body": "Dear Seelers and all cryptocurrency communities,\n\nToday the Seele Team has just announced that the Seele Token will be tradable on Huobi Korea from 28th June 2018 – below is the official announcement from the team!\n \n\nThis is massive news and further evidence that the Seele Team is focussing on bringing Seele Trading to a wider audience.\n\nToday’s news now means that Korean citizens can now legally purchase Seele tokens from 28th June.\nBut why is this such big news? What’s the big deal with Korea?\n\nWell in case you didn’t already know below are some notes on the popularity of cryptocurrency in Korea:\n\n1.\tAwareness for crypto is massive in Korea – some estimates put ownership of cryptocurrency at 33% in Korea. Truly staggering.\n2.\tDigital ownership is mainstream in Korea – in the past bitcoin prices have been as much as 40% higher in Korea due to the high demand for such assets.\n3.\tKorea is the 3rd biggest cryptocurrency market in the world. Yet it is only ranked at 27th in overall population size. This says a lot about how crypto has been adopted already in korea.\n\nSo, all-in-all making Seele available to the Korean masses is huge news when it comes to the widening of a community that can now invest in the Seele project.\n\nFurthermore, Huobi is a massive player in the crypto exchange market. It is quickly becoming a powerhouse and is constantly evolving and improving its customer experience.\n\nSome of the reasons that people have commented about like Huobi-pro so much are:\n\n•\tAvailable on Windows and Mac operating systems as well as through iOS and Android trading apps\n•\tAccess to a wide range of digital coins and tokens\n•\t24/7/365 customer service\n•\tPre-trade education programs for new users\n•\tCompetitive fees\n•\tEstablished in 2013\n\nHuobi Korea leverages off all the same technology and user interface. If you don’t believe me that go check it out here:\n\nhttps://www.huobi.co.kr/ko-KR/ \n\nA good article detailing the launch of Huobi in korea can be found here:\n\nhttps://news.bitcoin.com/huobi-officially-launches-south-korea-cryptocurrencies/ \n\nI would like to congratulate the Seele Team on making such a massive move into the Korean market. And just in time for the imminent Testnet release :)\n\nOnwards and upwards.\n\nCC.",

      "body": "Dear All,\n\nIt has been a few weeks since I wrote the below article:\n\nhttps://steemit.com/cryptocurrency/@cryptocroney/seele-blockchain-4-0-listed-on-hadax-what-attracted-me-to-the-project-and-how-is-it-progressing-since-ico \n\nSo what’s been happening in the meantime?\n\n1)\tGithub \nThe team has been super active on Github – lots of commits and lots of bug fixes. The forest is slowly being built out.  There have been 100’s of commits by over 20 developers. \n\n2)\tTestnet\nThe team has committed to releasing the testnet by the end of June – we are nearly there folks. Hold on to your hats for take-off!\n\n3)\tThe Seele Bounty\nI think that it is safe enough to say that the Seele bounty has been the best bounty ever seen. For a coin with such value it is staggering that the bounty pool is 5m tokens! Yes I did say 5m tokens!\nFrom meme’s to posters and tweets to social media posts the Seele Team is rewarding the entire community.\nOh and how could I forget the quiz? A staple in everyones day, twice a day  The team have really got creative with the quiz recently. The community is so engaged.\nOverall the bounty has been a mjor success in building an engaged and supportive community.\n\n4)\tSeele – the stable coin while there is blood on the streets\nThe price of the Seele token has been so solid since my last post – holding at 0.0005 ETH generally while most other ALT coins and Bitcoin values have been tanking hard.\n\nI just wanted to write a quick note today with the above and in anticpiitation of the testnet launch.\n\nI will be back with a much more indepth article once we have all gotten our hands on the testnet!!!\n\nSome useful links below – some extremely well written and interesting articles on Reddit and Medium:\n\nOfficial Email Address: [email protected] \nOfficial Website Link: https://seele.pro\nOfficial Announcement Channel: https://t.me/SeeleAnn\nOfficial Telegram Group: https://t.me/seeletech\nOfficial Telegram Asia: https://t.me/SeeleCN\nOfficial Twitter: https://twitter.com/SeeleTech\nOfficial Facebook Page: https://www.facebook.com/seeletech\nOfficial Reddit Page: https://www.reddit.com/r/SeeleOfficial\nOficial Medium Page: https://medium.com/seeletech",

      "body": "“A Universal Blockchain Protocol Enabling Cross-ledger Access through Business Modularization”\n\nBut what does this actually mean?\nOne Ledger wants to create an blockchain agnostic protocol that uses API’s to interact with the One Ledger Platform.\nWell to put it more simply One Ledger is a protocol that is designed to help businesses integrate their enterprise into blockchain technology.\nModularization tools are used to achieve this. Such tools reduce the complexity of the process and make it more attractive and viable for enterprises to adopt blockchain.\nIntegration API’s and blockchain agnostic architecture also form a vital part of the process.\nThese tools combined serve as a package for such enterprises when integrating to the blockchain.\nOne Ledger wants to foster interoperability between blockchains and eliminate congestion issues experienced on a main chain by offloading it to a side chain.\n\nThe One Ledger protocol offers a seamless and streamlined process for a variety of potential industries such as:\n\n![](https://cdn.steemitimages.com/DQmasMrQK6xy3hPs7u9gU8W54PiZxDofrkAz78f2G8zLf3p/image.png)\n\n \nA)\tThe One Ledger “selling points” and what makes it attractive\n\n1.\tOne Ledger aims to make the process of blockchain integration easier and accessible to those with the most basic level of blockchain experience; to enable them to create business applications on the One Ledger business portal which in turn communicates with the protocol via the API gateway.\n2.\tInformation is communicated between public and private blockchains using side-chains.\n3.\tSDK for smart contract deployment across multiple platforms\n4.\tUse of API’s\n5.\tHighly Scalable\n6.\tBlockchain agnostic\n\nB)\tLets take a look at the consensus model that One Ledger will use and how it works\n\nFirstly, One Ledger will use a 3-Layer consensus protocol. This is best illustrated by the below diagram taken from their website:\n\n![](https://cdn.steemitimages.com/DQmXS445VZj2D1DkQAA7YD5bopHed8hKJ3irv1nYPfT9dB9/image.png)\n \n\nRole Consensus layer: \tBusiness Logic is implemented on this layer using a “role based” consensus. The layer which defines a contracts role. \n\nSide Chain Consensus: \tUsed for moving traffic from the main chain to the side chain with high throughput. Consensus is Byzantine Fault Tolerant Partial Synchronization. Voting is utilized here.\n\nPublic Consensus: \tTransfer between public chains confirmed by public consensus. Pre-consensus is initiated on the side chain and then voted for consensus by validators of the public chain.\n\n\nC)\tThe OLT Token and its purpose\n\nThe OLT token fuels the One Ledger ecosystem. Those using the One Ledger business portal and its associated applications will pay for the service using OLT. Node operators will receive OLT tokens in return for maintaining and validating transactions within the ecosystem. Initially anyone can run a node but in time this may change to a staking approach and I assume the introduction of masternodes.\n\nOther Advantages of the One Ledger Ecosystem (taken from oneledger.io):\n\n•\tBusiness Modularization\nOne Ledger forms a realizable and verifiable blockchain network which is modularized from real-world functionality, based on the sharing and immunity mechanisms provided by blockchain techniques.\n•\tProtocol-based Blockchain Communication\nAll transaction data and real source records are written into distributed nodes by validation mechanism of data sharing through One Ledger protocol. One Ledger protocol enables communication and access across the blockchain, and allows for deployment and deployment across various Blockchain networks.\n•\tHigh-performance Transaction\nFocuses on providing a consistent runtime which is compatible with various blockchain protocols and application development stacks\n\n\nD)\tThe Team: I have summarised below the main members and who I consider to be the “Big Hitters” and “AllStars”\n\nDavid Cao is the Founder and CEO of One Ledger. David has a substantial track record as a developer and technical consultant with over 20 years of experience according to his LinkedIn. He is currently Chairman of the \nCanada China Blockchain Professional Association and from 2012-2017 served as Lead Commerce Consultant with Xerox.\n\nAlex Todd serves as CTA of One Ledger. Alex has extensive experience as an entrepreneur. He is the Founder and CEO of a blockchain-enabled social credit rating system called Trust 2 Pay. He is also former CTO of PRESTO, a company that integrated Ontario’s transit fare system.  \n\nThe Lead Engineer of the One Ledger ICO is Stephen Li. Stephen has over 15 years of experience as a developer since 2002. He has held positions with the likes of IBM and Morgan Stanley over his career, most recently with the latter as a full-stack web developer.  \n\nCEO of Polymath, Trevor Koverko, has joined the advisory team of One Ledger. \n\n\nE)\tProposed use cases for One Ledger\n\n\tSidechains move traffic for business while freeing up the main chain\n\tDApp’s due to the use of side chains (including open source)\n\tAsset identification amd transport flow\n\tDecentralized exchanegs\n\tAI flow for businesses\n\nF)\tThe Tokenomics\n\nTotal Supply:\t\t\t\t1,000,000,000 OLT\nHardcap\t\t\t\t\t15 million USD\n\nToken Sale\t\t\t\t\t35%\nCommunity Reserve\t\t\t25%\nTeam and Advisors\t\t\t\t15%\nCompany Reserve\t\t\t\t10%\nMarketing\t\t\t\t\t15%\n\nMy thoughts on the token metrics are that the hardcap is reasonable for what the team is trying to achieve. $15m is a very fair amount to be asking for.\n$10 million has been sold in private and presale rounds which have varying lock-ups and release stages. It is my understanding that these investors received bonuses of between 20% and 25%.\n$5 million is being sold to the crowd – this represents 33% of the USD raised – while obviously not 33% of the tokens (allowing for presale bonuses) again I feel this is a fair amount.\n\nTeam, Advisor and reserve tokens are all also locked with varying cliffs controlled by smart contract.\n\nThe token will be ERC20, at least initially until the main net arrives.\n\nG)\tFinal Thoughts\n\nOverall I am bullish on the project for the following reasons:\n\n\tThey are operating in a popular niche – that being providing a scaling solution for businesses looking for block integration while also making the process very user friendly.\n\tBlockchain Agnostic: The One Ledger SDK will allow for the deployment of DApps across multiple platforms and will incorporate Smart contract Templates which can be used/reused and tweaked when deploying new or multiple DApps at once (including cross platform).\n\tThe Team is seriously strong with a number of big hitters with both great business acumen and technical skills; with a track record of success.\n\tThe long road map has been an issue for some investors but I believe with a project of this magnitude it is going to take time to “get it right” – therefore lets “do things right”.\n\n\nBelow are some links to different links you may find useful:\n\nOfficial Website: https://oneledger.io/\nWhitepaper : https://oneledger.io/wp-content/uploads/2018/05/oneledger-whitepaper-05.17.18.pdf\nOfficial Telegram Group Chat : @oneledger\nOfficial Telegram Announcements Channel : @oneledger_official\nOfficial Chinese Telegram Channel : @oneledgercn\nTwitter : https://twitter.com/OneLedgerTech\nMedium : https://medium.com/@OneLedger\nReddit : https://www.reddit.com/r/OneLedger/\nGithub: https://github.com/Oneledger/\n\n\nThanks to anyone who took the time to read my review and feel free to leave your comments below.\n\nThanks.\n\nCC.",
