Elemental Chat Gets Freshened Up

Holochain Dev Pulse 93NOTE: Beginning this week, we’re trying something new with the Dev Pulse. We’re going to start publishing smaller pieces more regularly. We think this will make them both fresher and more digestible.This week we rolled out an update to all HoloPorts. The most visible changes are in the UI of Elemental Chat, our demo app. Users now have ‘identicons’ beside their name; these auto-generated avatars are based on their actual agent ID in the Holochain network and can’t be forged. This is important because usernames are just labels; you can set yours to anything you like, even someone else’s name. If you’re talking to a friend and suddenly their identicon looks slightly different, there’s a good chance someone is trying to impersonate your friend.This is an example of how cryptographically-secured data is a good first step to ensuring authenticity and accountability without the need for a central authority.Elemental ChatThere are some under-the-hood changes to Elemental Chat as well. The network stats are calculated more accurately (you can see them by clicking that graph icon in the upper-right corner). And the real-time performance of chatting (using signals) has been tweaked to be more efficient; this should result in a small performance improvement.Under the hood, the HoloPort’s operating system is using a new version of Holochain RSM. The reason this matters is that it prepares us for the next infrastructure milestone: hosted hApps! The speedups so far are modest, but we expect that other near-term updates will make Holochain substantially faster, fast enough to support thousands of users per app.These future updates will include:A switch to a new storage engine based on SQLite, the world’s most popular database engine. I know, I know, last year we said we were switching to LMDB because it was the best thing ever. And in comparable tests (hash table lookups) it does outperform SQLite. But we need more than just hash table lookups — we need fast querying with arbitrary filter parameters. This is especially important if we want to do neighbourhood sharding well. And sharding will lift the lid on scaling, allowing hApp networks to grow far beyond what traditional blockchains can reasonably handle.The proxy server, which helps HoloPorts and Holochain users punch through home firewalls, is in the midst of a large rewrite. So far, benchmarks predict that it’ll be 5× faster for raw throughput, at the very least. Once this is deployed, it will enable us to see places where DHT gossip and validation performance need to be improved.For developers, all of the above means that Holo hosting is on its way. The Holo Web SDK is being readied for public use as well, and we’re exploring the possibility of offering automated hApp testing services in a real hosting network on real HoloPorts.Special note for hApp devsThe develop branch of Holochain has advanced quite a bit past main in the past month or two, bringing features like the hc dev tool and hApp bundles. For that reason, I'm now recommending that you use https://nightly.holochain.love to install/enter the development shell. Also, take note that we might be changing installation URLs in the future, but we'll always keep the installation guide up to date for you.Cover photo by Paweł Czerwiński on UnsplashOriginally published at https://blog.holochain.org on April 5, 2021.Elemental Chat Gets Freshened Up was originally published in Holochain on Medium, where people are continuing the conversation by highlighting and responding to this story.

DeFi Needs Reliable Credit Scoring System, but We Must Be Cautious

A byline by our Founder, Li JunOriginally published in BeinCrypto.Credit scores have been a cornerstone of risk evaluation in the global banking systems for decades.They allow banks to determine who qualifies for a loan, at what interest rate, and what credit limits. Lenders use these scores to evaluate the likelihood that the borrower will fulfill their obligations and repay their loan.The global lending and payments market reached $6.7 trillion in 2020. It will possibly reach $7.6 trillion in 2021.If you’ve ever applied for a bank loan, you’ll know that these traditional credit scoring systems and in-depth identity verification processes work together. These include proof of address and a copy of a passport or official identification.Now, Europe’s Open Banking initiative, PSD2, is set to bring credit scoring into the 21st century.

MIXMARVEL INTRODUCES ITS LATEST PROJECT LECUBE DURING AMA HELD BY YGG

On April 13, MixMarvel Head of Global Marketing and spokesman Nicolas Zhu accepted the invitation to participate in the AMA conversation held by YGG, the world’s largest blockchain game community. This AMA’s goal was to provide an opportunity for the YGG community to learn more about MixMarvel’s latest project LeCube: who the team are and what they are working on.Having introduced MixMarvel, the leading blockchain game publishing platform and content community that connects high-quality content, players, and developers, Nicolas dove right into the main topic of the conversation — LeCube. LeCube is one of the significant projects MixMarvel is currently working on. LeCube is a called blockchain version of Lego and an art version of GitHub. In LeCube, users can use Cubes to compose and create entirely blockchain-based NFT assets with traceable copyright.LeCube is committed to changing the low state of collectibles lifetime, Nicolas stated. In LeCube, whether it is to generate the NFT code or compose the visual image in the NFT, it is directly created and stored using Ethereum’s smart contract. Therefore, the NFT created by LeCube ultimately gets rid of the dependence on centralized servers, making NFT a digital collection of a longer lifetime. LeCube NFT lifetime is proportional to the same of the Ethereum network.Nicolas specified that LeCube is currently under testing. Many players have already joined and built many outstanding creations in it.LeCube TokensThe first question the YGG host Kookoo rose up for discussion was what precisely the Cubes are and how players earn by playing the game. MixMarvel spokesman explained that Cubes are the primary materials used in LeCube’s creations. Users can mine Cubes in the Cube Pool by staking any community-agreed currency. Users can also get appropriate liquidity rewards by providing Cube liquidity on Uniswap. Users can compose Cubes to generate NFT assets and receive LCT token rewards for them. He also mentioned being absolutely fascinated by some of the good works created in LeCube, now featured on MixMarvel’s social media.Proceeding with the topic, Nicholas stated that in LeCube, each “Cube” is not only a Fungible Token with actual value but also the smallest unit of visual elements. In the process of composing the “Cube” (Fungible Token) into NFT (Non-Fungible Token), the value of all FT is transmitted to NFT, which constitutes the precise fundamental value of NFT and constructs all visual representations of the NFT. The entire process is directly completed using the Ethereum network, with higher asset value.Simultaneously, the user’s behavior of Cube composing can also be regarded as a Cube staking, which is conducive to the deflation of Cube volume and the preservation of Cube price. Users can choose to put their NFTs’ copyright in the Copyright Center and get corresponding LCT rewards when adopted by other users. The whole process is entirely on-chain and has unlimited data storage. Hence, users can decompose NFTs that are not of high quality at any time and return into the form of Cubes with better liquidity. This two-way transformable feature brings better liquidity to LeCube’s NFT. It provides a promising application scenario for FT, which can continuously promote the two. Nicolas also provided the chart below to illustrate the process.Cubes, NFTs, and LCTs each have separate missions, he elaborated, and constitute a stable ecosystem in which resources circulate continuously. At the same time, the assets are also converted to each other, forming a stable ecological structure. The roles of Cubes, NFTs, and LCTs will also evolve with the development of LeCube.Simultaneously, the half-cycle design will also allow the ecology to have the ability to evolve itself step by step: as the output of blocks decreases, the number of LCT rewards decreases, the fundamental value of NFT increases, and the community will gradually enter a consensus — NFT composing is the most profitable behavior. The generation of this consensus is also the mission of the LeCube project, Nicolas expressed.Cube PoolThe conversation expanded into more specific terms of LeCube. Kookoo inquired about one of the LeCube major modules, Cube Pool, and how users can participate.Answering this question, Nicolas declared that users can mine Cubes by staking practically any currency in the LeCube Cube Pool, as the currency that users stake for mining does not require any centralized organization’s permission. The community initiates an application for preselection contracts. The community votes by staking their preferred currencies. Finally, the top 21 currencies of the highest stake value will gain mining rights.After the stakes are complete, the Cube Pool’s output efficiency is not determined by any centralized organization but is generated by the market. The amount of Cubes obtained by the user is proportional to the stake value of all the currency they staked in the Cube Pool.Blockchain InfrastructureWhile discussing the Cubes details in blockchain, Kookoo got curious whether LeCube has plans to use layer 2 solutions since gas fees are ridiculously high. Regarding this question, LeCube already prepared its solution, proposing a relay-based, Ethereum-compatible blockchain infrastructure dedicated to systematically solving vertical industry problems.Although many blockchain infrastructures also provide partial solutions, Nicolas stated that they do not have many characteristics such as verticality, compatibility, and ease of use. They tend to replace Ethereum with the infrastructure of the decentralized financial field as the priority aim. Our solution to the issue is Rocket Protocol, another project that we incubate.Rocket Protocol is based on integrating and expanding the cross-chain, NFT, and EVM protocols. It allows developers to freely create decentralized applications that adapt to various scenarios while giving users an Internet application-like experience. In short, Rocket Protocol solves the problem of high-frequency transactions through the efficient VRF+BLS consensus mechanism and the data heterogeneity problem through the cross-chain solution based on the relay chain. It also solves the diversity problem through the horizontal expansion method and the interaction problem through real-time transaction confirmation.Images stored on centralized servers and assets of hard-to-confirm content sources are difficult to be called actual digital collectibles in the long run. Therefore, LeCube hopes to go further in the NFT direction and make digital collections more decentralized, coded, and capitalized. LeCube will provide a brand-new NFT creation and application paradigm, allowing on-chain native artwork creation so that images can be expressed in a decentralized manner.After Rocket Protocol is fully integrated with LeCube, MixMarvel and LeCube promise that this process will become faster. At the same time, the costs will be significantly shortened, allowing much higher-definition NFT images.Q&AOn such an encouraging note, the host finished this brief introduction of LeCube, allowing the present community to raise their questions. Users bombed the conversation with all the kind of questions. However, due to the time limitations, Mr. Nicolas Zhu could only choose several questions to answer.Answering the question of one of the YGG community users: “As I understand the gist of it after we BUILD our NFT from CUBE, the CUBE will be burned? And we have to mine/purchase pieces of Cube to build another NFT?” Nicolas stated that Cubes used to compose an NFT will be locked in it. To get the Cubes back, the NFT needs to be decomposed back into Cubes, and an LCT fee will be required.Another question that interested the users was how LeCube NFTs differentiate from any other. Although having mentioned this topic partially before, Nicolas elaborated on it in three points. First of all, he said, LeCube NFTs are much more durable digital collectibles.Secondly, being created entirely by the community, LeCue NFT becomes a more vibrant Digital Art. LeCube is committed to becoming an utterly open user UGC community. From the Cubes output and Cube composing to NFT creation, all the way until the community thoroughly completes the entire process. Compared with the mode of officially producing content and providing sales services, the user UGC community has a more diversified perspective. It can create richer content and burst out more substantial users’ self-propagation willingness.At last, LeCube NFT is simply a more valuable asset. In LeCube, each Cube is an FT, and each NFT is composed of these Cubes (FT). Since these Cubes (FTs), from output to circulation, have gone through a decent amount of community consensus and market game, they already have accurate market pricing, enabling NFT to have proper introductory pricing.At last, LeCube spokesman provided a list of all the media resources that may interest the users new to MixMarvel and LeCube in particular:LeCube Beta http://lc.mixmarvel.com/Rocket Protocol Twitter https://twitter.com/rocket_protocolMixMarvel Twitter https://twitter.com/MIXMARVELGAMEMixMarvel Telegram https://t.me/MixMarvelGlobalMixMarvel Discord https://discord.gg/dNPzkUqdThe discussions in the community went on long after the AMA finished.MIXMARVEL INTRODUCES ITS LATEST PROJECT LECUBE DURING AMA HELD BY YGG was originally published in MIXMARVEL Official Blog on Medium, where people are continuing the conversation by highlighting and responding to this story.

SpaceChain Callisto는 Linux및SpaceChain 운영체제 하에 사전설치하고 운영한다면 우주산업의 기술 개발에 속도를 내어 SpaceChain 페이로드 탑재와 발사의 버팀목이 될 것이다.오늘 SpaceChain은 우주에서 사용 및 배치 가능한 블록체인 애플리케이션 개발을 위한 오픈소스 데모 하드웨어 보드 SpaceChain Callisto를 출시한다.SpaceChain Callisto는 전세계 각지의 개발자 커뮤니티들이 항공우주 기술을 사용하여 블록체인 및 금융기술 애플리케이션을 위한 차세대 탈중앙화 인프라 구축에 참여하도록 한다. 무엇보다 이는 우주산업의 대중화와 상업화를 실현하기 위하여 전략적 첫발을 내디뎠다.Callisto의 배치방식은 국제우주 정거장에 설치된 궤도상 페이로드 배치 방식과 비슷하다. 개발자는 스마트계약, 다중서명 거래 등 블록체인 기능을 활용하여 획기적인 애플리케이션을 만들 수 있을 것이다. 또한 컴퓨터 실행 테스트를 통해서 개발자들이 개발한 애플리케이션은 우주에서 작동할지 여부를 결정한다.SpaceChain의 공동설립자이자 CEO Zee Zheng은 ‘우리는 소프트웨어가 위성을 컨트롤하는 시대를 살아가고 있다. 사람은 휴대전화를 조작하는 것처럼 하나의 애플리케이션이나 프로그램을 업로드하면 각기 다른 업무를 수행할 수 있고, 또한 참여자와 기여자 수를 늘리면 우주와 위성 기술을 위한 애플리케이션을 공개할 수 있다. 이를 통해서 더 많은 협력 기회를 창출해 이루지 못한 경제 모델을 만들고 새로운 업계에 활력을 불어넣을 수 있을 것이다.SpaceChain의 공동설립자이자 CTO Jeff Garzik는 ‘2020년 8월 우주에서 다중서명 블록체인 거래를 진행했다. 1년도 지나지 않아 SpaceChain은 기술 장벽을 없애고 전세계 커뮤니티가 우주 업계 관련 협력에 더 가까워지게끔 했다. 이와 동시에 검증된 블록체인 암호 기술을 통해서 그의 안전성과 안정성을 확보했다’고 말했다.Jeff Garzik 또한 ‘우리는 목성의 제2대 위성 Callisto의 이름을 사용하여 그대로 이름을 지었고 우리가 지구와 수백만 킬로미터 떨어진 물질을 통제하고 있다는 뜻을 표한다’고 말했다. 또한 ‘더 많은 우주 블록체인 위성 네트워크 상용화 케이스가 많아지면서 SpaceChain의 오픈 데모 하드웨어 보드는 우리가 우리의 혁신 기술을 적극적으로 보편화하고 있다는 사실을 말해주고 있다. SpaceChain의 응용체제가 각 지역에 있는 사람들에게 혜택을 가져다 준다는 목표와 더 가까워진다’고 덧붙였다.SpaceChain Callisto 소개와 SpaceChain Callisto 사용법에 대한 상세한 내용은 https://spacechain.com/callisto/및 https://github.com/spacechain/SpaceChain-Board를 참고한다.이곳을 클릭하면 SpaceChain Callisto보드 제품의 그림을 확인해 볼 수 있다.SpaceChain소개SpaceChain은 새로운 항공우주 경제의 탈중앙화된 인프라를 구축하는데 줄곧 노력해왔다. 또한, 우주산업의 기술과 블록체인 기술을 융합함으로써 SpaceChain은 우주에서 사용되는 애플리케이션의 개발 과정을 간소화하고 우주 기술을 보편화시키려고 끊임없이 노력을 기울여 왔다.미디어:Nicolette OngSpaceChain메일주소: nicolette@spacechain.comTony TanAutonomy연락처: +65–6570–9139메일주소: tony@autonomy-consulting.comSpaceChain, 우주에서 사용될 블록체인 애플리케이션 개발을 위한 프로그래밍 가능한 하드웨어 보드 출시 was originally published in SpaceChain on Medium, where people are continuing the conversation by highlighting and responding to this story.

Verge 04.13

Verge Currency’i tanımak adına…

Geçtiğimiz günlerde fazlaca konuşulan kripto-paralardan en çok dikkat çekenlerden biri olan ‘Verge Currency’; bazıları için 2017 boğa-sezonunda 1 haftada 25x yapan bir coin olarak bilinirken, bazıları için ise kripto ekosistemindeki temel sorunlara gereken çözümü sağlayan bir kurtarıcıdır.Pekala, neyin nesidir ki bu XVG?Öncelikle ‘ilk ışık’ olan Bitcoin’den başlamamız yeridir sanırsam… Bitcoin, 2008'in kriz zamanlarında, Satoshi Nakamoto mahlasına sahip bir, veya bir grup şahıs/şahısların ortaya çıkardığı dijital para birimidir. Kısaca,Güvenli: Kripto dünyasında bir söylem vardir. ‘Sizin şifreleriniz, sizin paranız’ diye. Bu da demek oluyor ki , size özel olarak tanimlanmış şifrelerinize sahip olduğunuz sürece, cüzdanınızı sadece siz kontrol edersiniz.Merkeziyetsiz: Hiçbir kurum/kuruluş, Ülke, Gezegen, veya Galaktik Federasyon sizin hesaplarınızı donduramaz. Elinizde Bitcoin veya benzeri bir kripto-para olduğu sürece, paranız vardır.Blockchain: Bitcoin ve birçok benzeri kripto-paralar, Blockchain denilen ağ üzerine kurulmuştur. Bunu örümcek ağı gibi düşünebilirsiniz. Ağın bir ucuna peygamber devesi konup bozmaya çalışırsa, tüm sistem bu titreşimi hisseder, ve örümcekler ivedilikle peygamber devesini kovmak için işe koyulurlar. Benzer bir şekilde, eğer kötü niyetli birisi, Blockchain’i modifiye etmeye çalışırsa, onun bağlı olduğu parçalar aracılığıyla bu hemen tespit edilir, ve amacına ulaşamaz.Günümüzde, özellikle ülkemizde, Bitcoin ve kripto-paralar’a olan ilgi, üstel bir artış göstermektedir. Bazılarımız gerçekten teknoloji ile alakası yokken, bazılarımız (hatta çoğumuz) doğru kripto-paralara yatırım yaparak sermayelerini katlamak derdindedir. Bugünün konusu olan Verge Currency ise, her türlü yatırımcının ilgisini çekip, hayran bırakabilecek bir teknolojiye sahiptir.Verge Currency(XVG), 2014 yılında Justin Valo(Sunerok) tarafından başlatılmış kar amacı gütmeyen açık kaynaklı bir projedir. Bitcoin teknolojisinin üstüne, birey ve şirketlere, hızlı ve ucuz para göndermek için bir yol sunmaktadır. Bir işlem 10 saniyeden bile az sürerken, ödediğiniz ücret 0.1 XVG kadardır. (Bunu yazdığım sırada, XVG’nin değeri 4 cent civarıdır, yani 33 kuruş.)Bitcoin’e göre çok daha düşük işlem ücreti olmasının yanı sıra, adresinizi gizleme özelliğine sahiptir. Bitcoin işlemlerinde herhangi birisi gerçekleştirilen para transferi ile adresinizi tespit edebiliyorken , XVG transferlerinde bunu tamamen görünmez olarak yapma fırsatına sahipsiniz.Peki, Verge Currency’nin ne olmadığına gelelim…Verge Currency, bir şirket değildir. XVG çıkmadan bir ön satışı olmamıştır ve açık kaynak olmasının getirdiği üzere, proje için çalışanlar gönüllüdür. Projeye dahil olan herkes her hangi bir maddi getiri beklemeden projeye destek olmaktadırlar.Şirket olmamasının yanı sıra, Verge Currency satın aldığınızda, hisse satın almazsınız, bir para birimi satın alırsınız. Kontrolünüz dışında insiyatife göre basılıp dağıtılan bir para birimi değildir. Topluluğu ve işleyişi son derece şeffaf olabilen, ve büyümesi sınırsız imkanlarla dolu bir para birimidir.XVG özünde sadece gizlilik odaklı bir Coin değildir. Son zamanlarda olaya tamamen hakim olmayan, veya sadece kaos amaçlı negatif haber yayan insanlar tarafından bu konuya dikkat çekildi İşlemleri tamamen saklayan bir Coin, hükümetler tarafından pek hoş karşılanmayabiliyor. Verge Currency’nin gizlilik özellikleri tamamen opsiyoneldir. Bu husus, XVG’yi birçok alanda kullanıma açık, esnek bir kripto-para haline getirmeyi başarmıştır.Her gün büyümekte olan Verge Currency’nin an itibariyle 99.32%’si madenciler tarafından üretilmiştir. Günümüzde madenciler ağın güvenliğini desteklemektedir. Aşağıdaki şekil sayesinde, ulaşılan kitlenin büyüklüğü ile ilgili bir fikir sahibi olabilirsiniz.Sosyal medyada Verge Currency’nin ulaşmayı başardığı kitleProjenin asıl amacı gündelik hayatta kullanılmak olduğu için buna dönük çalışmalar devam etmektedir. Proje’nin partnerleri, teknik detayları ve daha birçok bilgiye erişmek için websitemizi ziyaret edebilirsiniz.Verge CurrencyUyarı: Bu makalede yazılanlar tamamen bilgilendirme amaçlı olup, kesinlikle yatırımsal, finansal, veya herhangi başka bir şekilde tavsiye özelliği taşımamaktadır.Verge Currency’i tanımak adına… was originally published in vergecurrency on Medium, where people are continuing the conversation by highlighting and responding to this story.

Klaytn Usability Improvement Series #4: Supporting Role-Based Keys on the Platform-Level

See the list of articles here.🇰🇷: Klaytn 사용성 개선 #4: 플랫폼에서의 role-based key 지원Improving the usability of the blockchain platform has been one of Klaytn’s priorities. In this series of posts, we will walk you through the journey of improving the usability.Separating Keys and AddressesIntroducing Multisig on the Platform-LevelFee DelegationSupporting Role-Based Keys on the Platform-LevelImplementing Explicit Types for Accounts and TransactionsIn our last article, we took a look at a feature called Fee Delegation, which could enable blockchain services that offer the same level of user experience as existing services. In this post, we will be talking about role-based keys.An account on Klaytn fulfills the following functions:KLAY transferSmart contract deploymentSmart contract executionAccount information updateFee delegationWhat if we could use different keys for different functions? If we allow separate keys for features added on Klaytn, there could emerge new, diverse use cases. It was to this end that Klaytn designed and implemented role-based keys. We assigned roles for each function and designed so that different keys could be used for different roles. For a more in-depth explanation on Role-Based Keys, please refer to KlaytnDocs.A Key Just For Fee DelegationA service developer can consider paying for the user’s transaction fees using the Fee Delegation feature on Klaytn. But doing so would require that the operator of the Fee Delegation be given rights to transfer balances from the account, but you can’t just leave your account with a lot of balances to the operator. So, the simplest solution would be to manage a separate Fee Delegation account and continuously have it filled in with the necessary amount.But this approach has its downside; namely that you need to manage a separate account and check account balances on a regular basis for refill. Using Role-Based Key on Klaytn solves this problem by allowing the management of a Fee Delegation account with just one account. Here is a picture for clarification:The administrator of the account first takes the key for RoleTransaction. This key gives him the right to transfer balances of the account. The key for RoleFeePayer is given to the operator of the Fee Delegation. Since this key can let you pay for a transaction fee on others’ behalf, it can allow the operator to receive the users’ transactions and pay for their transaction fees. But since the key doesn’t allow transfer of balances, you can’t send it to another person. With this solution, you are spared of the inconveniences of owning a separate account, nor have to regularly check balances.Recovering User AccountA big obstacle in using blockchains is the private management of keys. But with Role-Based Keys, we can create scenarios where the users can recover their accounts. Let’s take a deeper look with the image below.The service developers first take RoleAccountUpdate key while issuing the accounts of individuals. The users are given a key for RoleTransaction. Users can send tokens, execute smart contracts using the RoleTransaction key. And if the key gets lost, service developers can reissue the RoleTransaction using RoleAccountUpdate key.With the new key, the user can seamlessly continue using the services, as if nothing happened.If you provide the new keys to the user, he or she can continue using the services with the account.In this article we looked at two cases using role-based keys. We hope role-based keys encourage the development of more services that make using blockchain easier. We expect more use cases in various service areas using this feature.In our next article of the usability improvement series, we will take a look at the improvement implemented for Klaytn account and transaction types. Thank you for reading, and stay tuned!Klaytn Usability Improvement Series #4: Supporting Role-Based Keys on the Platform-Level was originally published in Klaytn on Medium, where people are continuing the conversation by highlighting and responding to this story.

Monitor Beatport Tracks and Spotify Playlists with Viberate Charts

Here’s how you browse thousands of entries to spot the most influential ones.To navigate your way through the 3M+ tracks released on Beatport and the thousands of Spotify playlists your tracks could be featured on, you’ll need to put aside a good chunk of time. Or you could let Viberate analytics do the heavy lifting, without having to switch between different platforms and tools.To help you master analytics, we’ve introduced new subscription packages and a longer, 30-day free trial.https://medium.com/media/ecd7318d22abcb4444fbbbccdbda2a25/hrefYou can test-drive the Premium package with a 30-day free trial and see if it works for you. What’s more — if you claim your Artist, Venue, or Festival page during your trial, you’ll only pay 50% of the price later on. Sounds good?Now, let’s get to the upgrades.Our latest round introduced two useful features for artists, labels, and other music pros:🟢 the Beatport Tracks chart, analysing the performance and popularity of tracks and Beatport genres,💿 the Spotify Playlists chart, helping you pinpoint the playlists that would be a good fit for your tracks.#1 Analyse any track on Beatport with the Beatport Tracks chartRounding up our comprehensive Beatport analytics is the Chart feature. With it, you can review and evaluate every Beatport track’s performance through time, adjust your promotional efforts accordingly, and study similar tracks to spot trends in certain genres. Simply search for tracks directly in the search bar or apply the desired parameters, such as genre.Here are the stats for UMEK’s Vibrancy. Each entry shows a track’s release date, days spent on specific charts, and overall performance points.“Popularity” is the default setting, ranking tracks according to their time and positions on the Beatport Top 100 charts (which also translates to the tracks selling well).You can sort the chart by relevant genres and timeframes to narrow down your results, and determine how sought after your music could be. Viberate’s Beatport data goes back 8 years, so you’ll get valid metrics.#2 Find compatible playlists with the Spotify Playlists chartAs an artist, scoring a spot on the right playlist can take you places. Spotify playlists are a powerful promotional tool, so getting featured on the most followed ones can be a dream come true for many up-and-coming artists.The Viberate Spotify Playlists charts make it easier to browse hundreds of thousands of such playlists, choose those that fit your genre, and evaluate their potential reach.Obviously, a lot of high-ranking playlists are generated by Spotify itself, meaning that if you want to get featured on them, you’ll need to go through the company’s official submission process. But there are also loads of user-curated playlists that you can “investigate” further by simply clicking on them — the playlist in question will open in another tab.Pro tip: once you find an interesting playlist, see how many tracks are on it. The informal “Spotify standard” is between 20 and 50 tracks, as that’s a sign of two things: (1) the playlist is regularly curated, and (2) you’ll have a better chance of your track being heard than, say, fighting for attention with 300 other tracks.Go try it out and give your online stats a fresh boost.https://medium.com/media/7c1d0381dcc5a9ce08824baf3417e55c/href| Viberate.com |Instagram| Facebook | Twitter | LinkedIn | Reddit |Monitor Beatport Tracks and Spotify Playlists with Viberate Charts was originally published in Viberate on Medium, where people are continuing the conversation by highlighting and responding to this story.

SpaceChain Introduces Programmable Hardware Board for Developing Blockchain Applications that can be Deployed in SpaceThe SpaceChain Callisto development kit enables developer communities worldwide to participate in advancing next-generation decentralized infrastructures for blockchain and fintech applications using space technologiesSINGAPORE — April 14, 2021 — SpaceChain today introduced SpaceChain Callisto — its first open-source demo hardware board designed for developing blockchain applications that can be used and deployed in space. SpaceChain Callisto is pre-installed with and runs on Linux and SpaceChain Operating System (SPC OS), to help accelerate space technology development, and serves as the backbone for SpaceChain’s payload launches and missions.SpaceChain Callisto enables developer communities worldwide to participate in building out next-generation decentralized infrastructures for blockchain and fintech applications using space technologies. More importantly, it signifies a strategic step forward towards democratizing the space industry and fostering the commercialization of outer space.The Callisto is configured in a way similar to the on-orbit payload currently installed in the International Space Station. Developers will have the chance to create game-changing applications that can potentially leverage blockchain-related functions, including running smart contracts and performing multi-signature transactions, and running tests through their computers to determine whether the applications they created would work in space ultimately.“The world is entering an age of software-defined satellites that can be configured to perform different tasks by simply uploading an application or program, much akin to a mobile phone,” said Zee Zheng, SpaceChain co-founder and CEO. “By opening up access to space and satellite technologies through increasing the number of players and contributors, more opportunities for collaborative work can be created and lead to new businesses and socio-economic models that were once impossible.”SpaceChain’s co-founder and CTO Jeff Garzik executed the first multisignature blockchain transaction in space in August 2020. Less than a year later, SpaceChain is yet another step closer to removing barriers and allowing a global community to access and collaborate in space, all while remaining secure and immutable through proven blockchain cryptography.“We named our product — Callisto — after the second largest moon or natural satellite of Jupiter, to represent how a mass that is millions of kilometers from Earth can be held within our grasp,” said Jeff Garzik, SpaceChain co-founder and CTO. “SpaceChain’s open-source demo hardware board is proof of our efforts to bring our disruptive technology to the masses as we continue to discover more commercial use cases for blockchain-based satellite networks in space. We are one step closer to making the SpaceChain OS available to anyone, anywhere in the world.”More information about getting started with SpaceChain Callisto and how to use the board can be found at https://spacechain.com/callisto/ and https://github.com/spacechain/SpaceChain-Board.Please find below the product thumbnail of the SpaceChain Callisto board:High-res images can be found here.About SpaceChainSpaceChain fosters decentralized infrastructure for the New Space Economy.

History of Blockchain

In the 1990s, different works appeared on decentralized solutions to make electronic payments that laid the foundations for the birth of Blockchain technology: public-key cryptography, P2P networks, and timestamping.BeginningBlockchain, back in 1991 when the first work of a secure blockchain using cryptography, appeared under the authorship of Stuart Haber and W. Scott Stornetta. A year later, they incorporated Merkle trees to improve their prototype’s efficiency in handling tamper-proof digital documents.However, Haber and Stornetta’s work was not used and their patent expired in 2004, four years before the birth of Bitcoin.In 1998, Wei Dai described a decentralized solution for electronic payments based on public-key cryptography, which would lay the foundation for the transfer of digital properties.In 2004, computer scientist and crypto activist Hal Finney introduced a system called RPoW, which allowed the first digital transfer of tokens by solving the problem of double-spending.In 2008, based on Finney’s model, Satoshi Nakamoto introduced Bitcoin under a P2P system that shields transactions and verifies them in a fully decentralized network instead of the RPoW system.Since then, Blockchain technology has evolved to allow a set of scripts in the form of “Ethereum” smart contracts to web3 solutions that we see today with multiple existing platforms on the market.How Blockchain has EvolvedBlockchain 1.0: The Early YearsThe first version of Blockchain can be located in the timeline between 1991 and 2008, which marks the beginning of Blockchain and the first successful application of Blockchain technology, the birth of Bitcoin.Nakamoto conceptualized the first Blockchain in 2008 through his proposed ‘Bitcoin Whitepaper’, which outlined the details of how blockchain technology was well equipped to enhance digital trust.2. Blockchain 2.0: Welcome Ethereum and Smart ContractsAfter the birth of Bitcoin, there were many diatribes among the community to improve the Bitcoin ecosystem by taking advantage of the potential of Blockchain technology.In the absence of consensus, Vitalik Buterin, co-founder of the Bitcoin magazine and one of the Bitcoin network’s first collaborators, developed his own version of Blockchain to execute programmable scripts for certain use cases beyond digital payments.And in 2015, it delivered Ethereum, a decentralized public network that became popular today, hosting millions of transactions and decentralized applications (DApps) used in finance, gaming, education, logistics, health, and many other sectors.Together with Ethereum, proposals such as Zcash, Monero and DASH were born and focused on improving the privacy and scalability limit on Bitcoin.Chronologically, this period of Blockchain is placed by specialists in parallel to the birth of Bitcoin “2008” and its rival, Ethereum “2015”.3. Blockchain 3.0: web3 as the FutureThe history of Blockchain technology does not stop with cryptocurrencies like Bitcoin and Ethereum but goes forward with their respective decentralized networks. Due to the scalability problem of these networks, some Blockchain applications arose to take the massification of technology to a higher level.It is how we see the emergence of new Blockchain platforms such as Polkadot, FLETA and NEO, which are in the race to accelerate the development of technology. They have emerged with substantial improvements to generate decentralized applications with superior performance to handle the demand existing today.It is worth noting that the cases mentioned above include the so-called public(open source) blockchains and the private or federated ones, built by some corporations or associations such as R3 from Corda and Hyperledger from Linux.Advantages and Disadvantages of Blockchain VersionsBitcoin has been the forerunner of the application of Blockchain technology in all its brilliance, being the most secure decentralized network in the entire cryptocurrency ecosystem available.However, the limitations inherent in its original foundation make it impossible for it to be handled for some useful cases beyond a payment system or store of value.For the second generation Blockchains such as Ethereum, scalability problems have proven to be one of the pending aspects to be solved with ETH 2.0.It is important to note that new third-generation platforms will be responsible for maintaining the Blockchain boom and increasing its adoption.Problems such as interoperability, scalability, and high transaction costs are solved in recent projects such as FLETA, which guarantees an improved technological foundation to allow Blockchain adoption in any sector necessary to apply the distributed concept.Thanks to its block redesign, the use of sharding parallel and its own improved Proof of Formulation(PoF) algorithm, the key aspect of interoperability between chains is a reality within the Fleta ecosystem. It allows faster transactions under a real environment at a very low cost, compared to the first and second generation blockchains.ConclusionThe future of Blockchain technology looks bright. Much of this is due to the substantial improvements introduced to the ecosystem by new players such as FLETA, with technological foundations that allow it to handle the growing demand for decentralized applications.Blockchain technology is expected to help automate the majority of tasks handled by professionals in all sectors. Additionally, the way governments and businesses are waging this new digital battle makes the future look promising for one of the greatest inventions of all time.***About FLETAFLETA is a blockchain platform that aims to offer infrastructure that can be applied to real-world business models. FLETA has its own core blockchain technologies like Level Tree Validation, Parallel Sharding, Independent multi-chain Structure, Block Redesign, and PoF(Proof-of-Formulation) which is its own consensus algorithm. With them, it aims to solve the problems that existing platforms have such as slow speeds, scalability limitations and excessive fees, and provide a flexible development environment. Moreover, its Gateway technology improved its interoperability by allowing projects issuing their tokens through other mainnets to maintain their mainnets while using the FLETA chain.***Feel free to join and connect with us through our official channels below:Website: https://fleta.ioFLETA Store: https://fleta.ogn.app/#/Twitter: https://twitter.com/fletachainTelegram: https://t.me/FLETAofficialGroupGithub: https://github.com/fletaioHistory of Blockchain was originally published in FLETA on Medium, where people are continuing the conversation by highlighting and responding to this story.
