Mapping The Blockchain Project Ecosystem

Mapping The Blockchain Project Ecosystem

Joshua Nussbaum is a partner at the New York-based venture firm, Compound . Blockchain technology, cryptocurrencies, and token sales are all the rage right now. In the 5+ years Ive been working in the VC industry, this is by and large the fastest Ive seen any area of technology take off in terms of new company (or project) formation. It wasnt too long ago that founders and VCs were mainly focused on centralized exchanges, enterprise or private blockchain solutions, wallets, amongst several other popular blockchain startup ideas that dominated the market from 2012 to somewhere around 2016. However, as I wrote about a few months ago, the rise of Ethereum with its Turing-complete scripting language and the ability for developers to include state in each block, has paved the way for smart contract development. This has led to an influx of teams building decentralized projects seeking to take advantage of the most valuable property of blockchains the ability to reach a shared truth that everyone agrees on without intermediaries or a centralized authority. There are many exciting developments coming to market both in terms of improving existing blockchain functionality as well as the consumers experience. However, given the rapid pace at which projects are coming to market, Ive found it to be difficult to keep track of each and every project and where each one fits into the ecosystem. Furthermore, its easy to miss the forest for the trees without a comprehensive view of what the proverbial forest looks like. As a result, heres a compiled a list of all of the decentralized blockchain-based projects that I have been following, and was able to dig up through research, along with recommendations from friends in the ecosystem. A quick disclaimer: While its difficult to pigeonhole Continue reading >>

List Of Best Open Source Blockchain Platforms And Their Features

List Of Best Open Source Blockchain Platforms Open source software is a radical model oriented technology which enables the organization to fasten their development to initially reduce the cost entirely, and in return, it increases the innovation to get the goal of efficiency. We all know that none of the open source projects generates much confidence on the international position especially the Bitcoin blockchain technology. Now as our world is evolving people have started looking and considering other open source Blockchain platforms. However, here are some of the leading open source Blockchain platforms. This software allows anyone present in the platform to create as well as run an application from anywhere. This is dependable on the Blockchain or any smart contract technology that you use. A governmentcan use these smart contracts to do business with Eris automatically. It is a big time free software that allows to completely commence and build an own secure, low-cost, run-anywhere applications using blockchain and smart contract technology. It depends on the kinds of stuff that you turn on and off. Further, this will help to directly develop a group of a permission-ed chain for the individuals. Along with the provision of smart contract tool chain, it has an instrument to analyze the complete action step by step manner. This software is an extension of the Ethereum platform which helps to create a Permissioned which is attached to the Distributed Ledgers. The application in this software is private chain oriented and is mainly set up for the financial industry. This extension is the most compatible software to the Ethereum Protocol, and it has an instant finality to the process it initiates. The contracts involved in this extension is of native. Moreover, it is f Continue reading >>

5 Blockchain Platforms To Keep Your Eye On In 2018

5 Blockchain Platforms To Keep Your Eye On In 2018

5 Blockchain Platforms to Keep Your Eye On In 2018 2017 was the year blockchain technology and cryptocurrencies went mainstream. Bitcoin, Ethereum, and viable blockchain use cases went from being far-off futuristic ideas to a reality that some of the biggest companies in the world support. Bitcoin futures markets just opened, proving a growing interest in cryptocurrencies from formal institutions and investors. And blockchain has proven itself time and time again to be a disruptive force. According to CNBC there was more capital raised through ICOs in 2017 than traditional venture capitalover $1.2 billion, to be more specific. If the past year is any indication of the growing interest in blockchain technology, then 2018 will be its biggest year yet. Whats most impressive about the entire crypto and blockchain movement, however, is how many innovative ideas have come about as a result. Ethereum has established itself as the go-to platform for blockchain startups and decentralized applications, and many entrepreneurs have jumped at the opportunity to build disruptive solutions for outdated industries. Here are 5 interesting blockchain platforms to keep your eye on in 2018: One of Ethereums biggest problems is its ability to process thousands of transactions per second. As it stands, Ethereum can only process about 10 transactions per secondwhereas Visa can process close to 2,000. The Raiden Network is a scaling solution built specifically for the Ethereum platform, with the goal of moving the bulk of those transactions off-chain so that the Ethereum blockchain can act more as a net ledger. This would allow Ethereum to process many more transactions per second, and ultimately scale into a more powerful solution for all other blockchain startups looking to leverage the pla Continue reading >>

The Blockchain: A Comparison Of Platforms And Their Uses Beyond Bitcoin

The Blockchain: A Comparison Of Platforms And Their Uses Beyond Bitcoin

The Blockchain: A Comparison of Platforms and Their Uses Beyond Bitcoin COMS4507 - Advanced Computer and Network Security AbstractThis paper presents a comparison of ve general-use blockchain platforms. We rst discuss how the blockchain is used in Bitcoin, before looking at how blockchain technology can be used in applications outside of Bitcoin. We conduct an investigation into the blockchain platforms available for users to build custom applications on top of. We conclude with a summary of our ndings and some suggestions for future work. After capturing worldwide attention through its novel combination of ideas, underpinned by decades of research, Bitcoin has become one of the most successful digital currencies to date [1]. Blockchain technology was key to this success, and although conceived to support the ideas and goals of Bitcoin, researchers and esoteric thinkers alike have since realised the potential of blockchain in applications This potential is because the blockchain was designed to support the unique requirements of a digital currency, which can be desirable in many other situations. These requirements include decentralised management, anonymity, immutability, forgery resistance, and prevention of the dou- ble spend problem - a non-trivial problem to solve in a dis- tributed setting that does not have an overseeing centralised Since the release of the white paper by Satoshi Nakamoto proposing Bitcoin as a viable peer-to-peer digital currency, academic research in this space has increased and other applications using blockchain technology have begun to surface. Some examples include reputation systems [2], contract management systems [3], and digital content distribution systems [4]. In response, several blockchain platforms have been developed. These platf Continue reading >>

Review Of The 6 Major Blockchain Protocols

Review Of The 6 Major Blockchain Protocols

Review of the 6 Major Blockchain Protocols Since 2008, when the term bitcoin was coined by Satoshi Nakamoto as a novel electronic and completely peer-to-peer cash system free of trusted third party , the interest in the bitcoin and blockchain technology has increased. Recognizing it as a revolutionizing technology across the industries, especially in banking and finance, in terms of transactions and their privacy and security, researchers are not leaving any stone unturned to come up with exotic protocols with each passing day and each is the newer, advancer and better protocol than the previous. In continuation to the blockchain series on TheBlockchainAcademy.com , I have included 6 major blockchain protocols, so as to embrace the technology and increase awareness among investors and end users of blockchain. The starting of the bitcoin dates back to November 2008, when a thesis had been posted by Nakamoto on a US mailing list where the cryptographers share or exchange information. The thesis titled Bitcoin: A peer-to-peer electronic cash system , presented the following characteristics of this protocol: Enables transaction directly with no need of any trusted third party Decreases credit cost in minor casual transactions Bitcoins are virtual currency, also called cryptocurrency . These are distributed while exploring the value in the data managed by software. The start of 2016 witnessed the issuance of around 15.26 million BTC, equivalent to around 7 billion US Dollars . Major technologies that make Bitcoin include hash, digital signature, public-key cryptography , P2P and Proof of Work. This blend has developed a mechanism that prevents duplication of payments and data falsification, additioinally a mechanism that prevents malicious users, which are critical for the Continue reading >>

The Evolution Of Blockchain Technology | Deloitte Insights

Repositories reveal interesting trends about organizations The core code supporting Bitcoin was published in April 2009. Since then, the number of projects on GitHub related to blockchain has grown significantly, averaging more than 8,600 new projects a year. In 2016 alone, there were almost 27,000 new projects (figure 3). The growth in the number of projects has been matched by the rapid growth of content produced to develop these blockchain technologies. Please see figure 4, and Repositories by year in our interactive dashboard. In analyzing blockchain repositories and their content, we noticed that increasingly more organizations appear to be getting involved. In 2010, organizations developed less than 1 percent of all projects. By 2017, their blockchain projects accounted for 11 percent (organizations currently account for 7 percent of totalnot just blockchainsoftware development on GitHub). And recent data about the rate at which commercial organizations can find success with blockchain initiatives through open source seems promising; some high-profile, large commercial entities are already doing so. (Please refer to Repositories by organization in our interactive dashboard.) Of particular significance, some projects that organizations have developed have resulted in new platforms (such as Ethereum, Ripple, Corda, and Quorum) which some developers now use to build applications. Organization-owned projects also tend to be updated more frequently than those developed by users, and are reportedly five times more likely to be copied, implying that the blockchain community has deemed them most relevant. When a project is copied, all of the content becomes available to the account that copied the project, thus working as a de facto knowledge-transfer mechanism. This pro Continue reading >>

Blockchain Platforms: One Chain To Rule Themall?

Blockchain Platforms: One Chain To Rule Themall?

Entrepreneur and blockchain investor, analyst and aficionado. Founder of Eden Block, a blockchain investment and research vehicle. Blockchain Platforms: One Chain to rule themall? Everyone asks: is the world ready for Blockchain? But more importantly, is Blockchain ready forus? 2017 was the year that blockchain made its way into the mainstreams consciousness. To the outside world, todays hot topics are is Bitcoin a bubble, and where can I get Ripple? But people are missing the point. Theyre missing the fundamental question that we should all be asking. I dont believe that todays focus should revolve around whether or not Bitcoin will still be around a few years from now. A more intriguing question is: how will blockchain really change the world? And even that question fails to consider whether the blockchains we have today can actually support these world changing applications. 2018 is set to be a defining year for Blockchain, with many projects set to release a working product or application, and a likely flood of newly converted institutional money. However, this exponentially growing market will continue to strongly highlight whether Blockchains can or could support a decentralised world. In this piece, well cover a handful of concepts and ideas and go into some technical aspects. Ill try not to delve too deep into individual concepts, so feel free to research further any of the topics we cover. The evolution of blockchain & blockchain 2.0 Bitcoin was the first. It was exciting. Revolutionary. It was Steve Jobs in his basement, Neil Armstrong walking on the moon, the caveman harnessing fire. It was the first digitally scarce asset. It solved issues that had plagued developers for years. It is the foundation of this entirely new class of assets. However, just like mo Continue reading >>

Types Of Blockchains

Types Of Blockchains

Blockchains & Distributed Ledger Technologies The Bitcoin White Paper was published by Satoshi Nakamoto in 2008; the first Bitcoin block got mined in 2009. Since the Bitcoin protocol is open source, anyone could take the protocol, fork it (modify the code), and start their own version of P2P money. Many so-called altcoins emerged and tried to be a better, faster or more anonymous than Bitcoin. Soon the code was not only altered to create better cryptocurrencies, but some projects also tried to alter the idea ofblockchain beyond the use case of P2P money. The idea emerged that the Bitcoin blockchain could be in fact used for any kind of value transaction or any kind of agreement such as P2P insurance, P2P energy trading, P2P ride sharing, etc. Colored Coins and Mastercoin tried to solvethat problem based on the Bitcoin Blockchain Protocol. TheEthereum project decided to create their own blockchain, with very different properties than Bitcoin, decoupling the smart contract layer from the core blockchain protocol, offering a radical new way to create online markets and programmable transactions known as Smart Contracts . Private institutions like banks realized that they could use the core idea of blockchain as a distributed ledger technology (DLT), and create a permissionedblockchain (privateor federated), where the validator is a member of aconsortium or separate legal entities of the same organization. The term blockchain in the context of permissioned privateledger is highly controversial and disputed. This is why the term distributed ledger technologies emerged as a more general term. Private blockchains are valuable for solving efficiency, security and fraud problems within traditional financial institutions, but only incrementally. Its not very likely that private Continue reading >>

Battle Of The Blockchains: From Bitcoin To Lisk, Five Different Types Of Blockchain Explained

Battle Of The Blockchains: From Bitcoin To Lisk, Five Different Types Of Blockchain Explained

Battle of the blockchains: From Bitcoin to Lisk, five different types of blockchain explained Dominic Powell / Thursday, December 7, 2017 A common misconception when discussing the enigmatic technology of the blockchain is that the technology hangs off just one sort of blockchain usually assumed to be the same one that the techs first use case, Bitcoin, is based on. But in reality, blockchain technology is better compared to different types of operating systems, or programming languages. The overall aim and, in most cases, the baseline technology is all the same, but the technologys functionality, primary use case, and ways it interacts with developersand consumers can differ wildly. So for startups looking to this emerging technology as a way to develop new avenues for their product, or for founders looking to start a new venture altogether, heres a quick breakdown of some of the main options when it comes to picking a blockchain. The $16,000 poster child of the blockchain, Bitcoins underlying technology pioneered the concept of a distributed ledger, with its mysterious origin story and baffling valuation bringing the tech into the spotlight. Unfortunately, the Bitcoin blockchain is somewhat outdated these days, especially compared to other available options, with average transaction times sitting above 30 minutes, and transaction fees reaching over $US20 at its peak. The Bitcoin community has been engaged in multiple, at times fierce, debates over ways to best scale the currencys blockchain, but a lack of consensus has stagnated development. Its for this reason that most deviations from the original Bitcoin Core blockchain mostly focus on Bitcoins original proposition as a peer-to-peer electronic cash system. These include things like centralised mining resistant Ver Continue reading >>

What's The Difference Between Dapps And Blockchain Platforms?

What's The Difference Between Dapps And Blockchain Platforms?

What's the difference between DApps and blockchain platforms? Alex Lielacher , 11 Mar 2018 - Blockchain , Dapps , Ethereum , Ico If you are a potential investor in the blockchain space it can be difficult to differentiate between all the companies claiming to be the next disruptor of an industry. The conflating of terms like blockchain technology, smart contracts and decentralised applications (DApps) can make due diligence of ICOs particularly fraught. However, once you have filtered through the list of en vogue buzzwords in these projects press releases you need to understandwhat the project really entails, whether it will actually be decentralized and whether it even needs a blockchain to function. Decentralized applications (DApps) are software applications that are running their backend code on a blockchain and require no middleman to run. Once a decentralized blockchain is created its contracts (code) exists in an open state outside of the control of its creators. To take the example of a social mediadApp created on a blockchain where any user can 'tweet' messages. Once a tweet is posted, no one including the app creators can delete that post. Editing may be possible by the sender, but the original would be retained forever . The most common features of DApps include Open Source. This means that its code base is publicly open to access for scrutiny and changes. It should be governed by autonomy and all changes must be decided by the consensus, or a majority, of its users. Decentralized. All records of the applications operation must be stored on a public and decentralized blockchain. Incentivized. Validators of the blockchain should be incentivized by rewarding them accordingly with cryptographic tokens. Protocol. The application community must agree on a cryptog Continue reading >>

Main Blockchain Platform Types

Main Blockchain Platform Types

Managing Consultant at Delta Science BV | Data Analytics | Blockchain Visualisations The Blockchain I described in my previous blog, described the properties of a public Blockchain. At the moment, there are multiple Blockchain platforms, that can be divided into multiple types. Two main examples are public and private Blockchain, see below image for their characteristics. Besides the public and private Blockchain, there is also the consortium Blockchain, I will explain all three of them and their differences in more detail. First of all, there are the public Blockchains, these are completely decentralized. Everyone who is interested, can join these Blockchains. You only need a computer with internet access and the software to execute transactions on the Blockchain. Everyone who creates transactions on the public Blockchains can be assured that the approved transactions will be included in the Blockchain. Everyone can see all transactions from everybody. It is necessary to build in some kind of trust, because the Blockchain is based on cooperation between participants who do not know each other, without the supervision of a central third party. This trust is built in by a mix of cryptography and economic stimuli, where participants are rewarded when the stick to the agreed rules. Everyone can join in the process where transactions are verified and added to the ledger. This is the process where the participants agree upon the truth. A variation of the public Blockchain is the private Blockchain, this is a closed system. Where usually one company is owner of the Blockchain, who can make all decisions. To a certain extent the private Blockchain lets the middleman back in. The owner writes and verifies each transaction. This will lead to far more efficiency and the verifica Continue reading >>

Five Blockchain Technologies You Should Be Watching

Five Blockchain Technologies You Should Be Watching

Five Blockchain Technologies you should be Watching Blockchain is much bigger than bitcoin. There is staggering innovation in the area of distributed ledgers, but most of it will be under the radar for anyone who hasnt immersed themselves in that world. Here are five technologies and trends to watch. Bitcoin decentralises money, removing the requirement for a middleman and enabling trustless peer-to-peer transactions. Now, imagine you could do the same for computer code. The result would be a programme that executed instructions when certain conditions were met, and no one could stop it because it ran on a virtual computer distributed on thousands of different machines across the planet. Smart contracts do just that. Ethereum is the most famous smart contracts platform, though that reputation tipped over into infamy when its flagship application went rogue. Smart contracts do exactly what you tell them to; they operate under a code is law model. The DAO a virtual company that managed well over a hundred million dollars worth of Ethereum based on the collective decisions of it holders was exploited, and tens of millions of dollars drained from it. It caused an existential crisis for Ethereum, whose community had to decide whether to rewrite the supposedly immutable blockchain to reverse the damage. (In the end, they did a decision which was hugely controversial and that has had far-reaching ramifications.) Amongst other issues, it raised the question of how smart smart contracts really are. There are also questions about the scalability and energy cost of creating a planet-sized computer to run relatively simple programmes, though other platforms, like Lisk, take a different and more efficient approach. Bottom line: smart contracts are a powerful idea and well be seeing Continue reading >>

For other uses, see Block chain (disambiguation) . Blockchain formation. The main chain (black) consists of the longest series of blocks from the genesis block (green) to the current block. Orphan blocks (purple) exist outside of the main chain. A blockchain [1] [2] [3] originally block chain [4] [5] is a continuously growing list of records , called blocks, which are linked and secured using cryptography . [1] [6] Each block typically contains a hash pointer as a link to a previous block, [6] a timestamp and transaction data. [7] By design, blockchains are inherently resistant to modification of the data. Harvard Business Review defines it as "an open, distributed ledger that can record transactions between two parties efficiently and in a verifiable and permanent way." [8] For use as a distributed ledger, a blockchain is typically managed by a peer-to-peer network collectively adhering to a protocol for validating new blocks. Once recorded, the data in any given block cannot be altered retroactively without the alteration of all subsequent blocks, which requires collusion of the network majority. Blockchains are secure by design and are an example of a distributed computing system with high Byzantine fault tolerance . Decentralized consensus has therefore been achieved with a blockchain. [9] This makes blockchains potentially suitable for the recording of events, medical records, [10] [11] and other records management activities, such as identity management , [12] [13] [14] transaction processing , documenting provenance , or food traceability . [15] The first blockchain was conceptualised in 2008 by an anonymous person or group known as Satoshi Nakamoto and implemented in 2009 as a core component of bitcoin where it serves as the public ledger for all transactions.

Top 8 Blockchain Platforms You Should Check Out Now Blockchain , Latest B2B News , Software , Technology , Top News September 3, 2017February 14, 2018 Jyoti Bharwani In 2008 Blockchain technology was introduced in a paper titled Bitcoin: A Peer-to-Peer Electronic Cash System by Satoshi Nakamoto. When it comes to talking about this high-end technology, it is a creative invention that interests various people. Since then, this technology has grown into something greater. One of the major questions every single person has in his/her mind is: What exactly is Blockchain Technology ? A Blockchain is the data structure that is used by Bitcoin cryptocurrency for its public ledger, where transactions can be recorded. Unfortunately, the word Blockchain does not appear in the real description of the Bitcoin protocol. It was referred to as the chains of blocks in a comment in the source code for its operation. Equipped with enormous features, Blockchain is a perfect for decentralized and secure processing of events and transactions. Decentralization of a business process leads to quicker processing and less overhead. Moreover, secured processing makes sure that the managing parties cant hack the system and any attempt to do so can be easily noticed. Some of the major use cases of Blockchain technology are organized supply chain, tracking of calculable or tangible assets, multiparty financial transaction, etc. These top 8 Blockchain platforms can help you to prototype your next big idea: Ethereum is well-known for running smart contracts, applications that run the same as programmed without downtime, third-party interference and censorship. It allows developers to create stored registries of debts, markets, move funds according to instructions that given back in the past. In this l Continue reading >>
