Dec 01, · F or the tenth anniversary of the Forbes 30 Under 30 list of business leaders paving the way for future generations, eleven bitcoin and blockchain leaders were . Bitcoin blockchain structure A blockchain, originally block chain, is a growing list of records, called blocks, that are linked using cryptography. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data (generally represented as a Merkle tree). By design, a blockchain is resistant to modification of its data. This is because once recorded, the data in. Apr 28, · Bitcoin, ether and XRP exchanges are building their own native blockchain networks to build an economic moat and grow market share. But they are also developing for different use cases.
Is bitcoin a blockchain platformBlockchain: Everything You Need to Know
It is a simple and modularized distributed ledger system based on a highly secure and fast consensus algorithm called Yet Another Consensus, protecting Iroha networks from adversary nodes or failures. Being portable and supporting macOS and Linux environment, the platform is highly applicable for supply chain and IoT use cases.
Corda is a cutting-edge blockchain platform, which enables institutions to transact directly with smart contracts by removing costly frictions in business transactions.
Corda does not have a cryptocurrency or built-in token and is a permissioned blockchain platform which only allows the authorized participants to access the data, not the entire network. Since it operates in a permissioned mode, it enhances privacy and offers fine-grained access control to digital records.
Designed initially by the financial industry, for the financial sector, Corda is now being applied in various other uses cases like healthcare, trade finance, supply chain, and government authorities. More than 60 firms, including Intel and Microsoft, are using Corda as a blockchain platform. Launched as open-source software in June , EOS is a blockchain platform founded by a private company, Block. It is designed for the development of dApps Decentralized applications.
The company distributed one billion ERC tokens to ensure widespread distribution of their cryptocurrency and allow anyone to use EOS blockchain after it was released. Also, it eliminates the fees for all users, i. EOS accomplishes consensus by using multi-threading as well as a delegated proof-of-stake algorithm.
They have their own community forum named as EOS Forum, enabling developers and investors to discuss the platform and EOS Talk for their users based on the steem blockchain. OpenChain is an open-source distributed ledger technology, highly suited for organizations willing to manage the digital assets in a secure and scalable manner. Unlike the consensus mechanism used in Bitcoin, it uses Partionned Consensus where one instance will only have a single authority for validation of transactions.
Since there is no miner in the OpenChain, the transactions are free of costs and can be validated by the asset administrator, making it more efficient than other platforms.
Stellar is a distributed blockchain based ledger used for facilitating cross-asset transfers of value. Similar to Ripple, it can also deal with exchanges between cryptocurrencies and fiat based currencies. It is possible to build banking tools, smart devices and mobile wallets using the Stellar network.
Stellar Consensus Protocol SCP makes it possible to reach consensus without depending on a closed system for recording financial transactions. Having a set of provable safety properties, SCP optimizes for safety over liveness by halting the progress of the network until a consensus can be reached in case of misbehaving nodes or partition. As compared to the decentralized proof-of-work and proof-of-stake algorithms, SCP has modest financial and computing requirements, reducing the barrier to entry and opening up financial system to new participants.
SureRemit leverages Stellar blockchain for connecting immigrants in abroad with the merchants providing the services required by their loved ones in a different country. Originally developed at the Walt Disney Company in and open-sourced later in , the Dragonchain platform has been specifically designed for enterprises.
Their blockchain as a service offers flexibility to businesses by allowing them to utilize Interchain that provides the capabilities of other blockchains. With their cloud-based model for Blockchain as a Service, the need for patch implementation, updates and server setup is eliminated.
Also, the platform can support any programming language, including Python, Node. With five levels of consensus, Dragonchain offers a wide spectrum of trust and allows users to use multiple proof protocols. The role of NEO token is to generate GAS tokens which can be used to pay transaction fees to run applications on the network.
Neo uses Delegated Byzantine Fault Tolerance as its consensus algorithm. The creators of Neo selected this protocol because it allows better performance and scaling as compared to other consensus mechanisms. Since blockchain is moving at a frenetic pace of innovation, new platforms have started to emerge with additional features and new releases. No doubt that there are plenty of blockchain platforms available across the world, enterprises need to understand the right platforms to build highly scalable applications.

How to select a Blockchain Platform for your business? Akash Takyar. Akash is an early adopter of new technology, a passionate technology enthusiast, and an investor in AI and IoT startups. Write to Akash. What is the development status of a platform? What type of Blockchain do you require?
What Languages does the platform support? How popular is the platform? Look at the reputation of a blockchain platform on websites like GitHub or Reddit. What Blockchain Consensus Protocol does the platform use to achieve consensus?
Does the platform support Smart Contracts Functionality? What kind of scalability does your solution need? Hyperledger Fabric. Hyperledger Sawtooth. Hedera Hashgraph. Hyperledger Iroha. Here is the comparison of best blockchain platforms used by companies for building blockchain based applications. Having the capability to handle hundreds of thousands of transactions per second and authenticate more than one million signatures per second, time to finality for the Hedera platform is measured in seconds; not minutes, hours, or days.
Fair Hedera Hashgraph is fair, ensuring the consensus order of transactions which represents the transaction order received by the community. The platform makes sure no single user is allowed to block the transactions flow into the community.
Secure As Hedera Hashgraph is an asynchronous Byzantine fault tolerant, Hedera Hashgraph has the strongest level of security.
Achieving this level of security at scale is a fundamental advance in the field of distributed systems. Transparent Process While the transactions on Fabric might be obfuscated, the development process is not. In fact, the core teams behind Hyperledger have worked hard to create a healthy balance between transparency in the development process and attaining important milestones.
Smart Contracts Hyperledger also uses chain code smart contracts just like Ethereum does. Features The EOS platform provides the producers with a governance system which they can use to vote on to validate transactions, edits made to the source code of the platform and confirm whether an application is performing correctly.
Authenticity The platform offers a fully-featured authentication platform to the users where each account will be given a different permission level to save data in a secure manner. Using blockchain, assets digitization can be trustful, transparent, traceable, free of intermediaries and decentralized.
Users can register, trade and transfer different types of digital assets on the Neo platform. Digital Identity Identity information that remains in the form of electronic data is referred to as digital identity. Neo maintains a set of X. Smart Contract Using Neo SmartContract system, developers do not require to learn a new programming language. Rather, they can use Java, C or other languages to develop smart contracts. Blockchain is also being used in peer-to-peer energy trading. There are a number of efforts and industry organizations working to employ blockchains in supply chain management.
Hospitals and vendors also utilized a blockchain for needed medical equipment. Additionally, blockchain technology was being used in China to speed up the time it takes for health insurance payments to be paid to health-care providers and patients. Blockchain domain names are another use of blockchain on the rise. Unlike regular domain names, blockchain domain names are entirely an asset of the domain owner and can only be controlled by the owner through a private key.
Organizations providing blockchain domain name services include Unstoppable Domains, Namecoin and Ethereum Name Services. Blockchain technology can be used to create a permanent, public, transparent ledger system for compiling data on sales, tracking digital use and payments to content creators, such as wireless users  or musicians.
New distribution methods are available for the insurance industry such as peer-to-peer insurance , parametric insurance and microinsurance following the adoption of blockchain.
Institute of Museum and Library Services. Currently, there are at least four types of blockchain networks — public blockchains, private blockchains, consortium blockchains and hybrid blockchains. A public blockchain has absolutely no access restrictions. Anyone with an Internet connection can send transactions to it as well as become a validator i. Some of the largest, most known public blockchains are the bitcoin blockchain and the Ethereum blockchain.
A private blockchain is permissioned. Participant and validator access is restricted. To distinguish between open blockchains and other peer-to-peer decentralized database applications that are not open ad-hoc compute clusters, the terminology Distributed Ledger DLT is normally used for private blockchains.
A hybrid blockchain has a combination of centralized and decentralized features. A sidechain is a designation for a blockchain ledger that runs in parallel to a primary blockchain. With the increasing number of blockchain systems appearing, even only those that support cryptocurrencies, blockchain interoperability is becoming a topic of major importance.
The objective is to support transferring assets from one blockchain system to another blockchain system. Wegner  stated that "interoperability is the ability of two or more software components to cooperate despite differences in language, interface, and execution platform". The objective of blockchain interoperability is therefore to support such cooperation among blockchain systems, despite those kinds of differences.
There are already several blockchain interoperability solutions available. The IETF has a recent Blockchain-interop working group that already produced the draft of a blockchain interoperability architecture. The adoption rates, as studied by Catalini and Tucker , revealed that when people who typically adopt technologies early are given delayed access, they tend to reject the technology. Motivations for adopting blockchain technology have been investigated by researchers. Janssen et al.
Scholars in business and management have started studying the role of blockchains to support collaboration. Thanks to reliability, transparency, traceability of records, and information immutability, blockchains facilitate collaboration in a way that differs both from the traditional use of contracts and from relational norms. In addition, contrary to the use of relational norms, blockchains do not require trust or direct connections between collaborators.
The need for internal audit to provide effective oversight of organizational efficiency will require a change in the way that information is accessed in new formats. The Institute of Internal Auditors has identified the need for internal auditors to address this transformational technology. New methods are required to develop audit plans that identify threats and risks.
The Bank for International Settlements has criticized the public proof-of-work blockchains for high energy consumption. In September , the first peer-reviewed academic journal dedicated to cryptocurrency and blockchain technology research, Ledger , was announced. The inaugural issue was published in December The journal encourages authors to digitally sign a file hash of submitted papers, which are then timestamped into the bitcoin blockchain.
Authors are also asked to include a personal bitcoin address in the first page of their papers for non-repudiation purposes. From Wikipedia, the free encyclopedia. For other uses, see Block chain disambiguation. It has been suggested that Blockchain-based database be merged into this article.
Discuss Proposed since April If one group of nodes continues to use the old software while the other nodes use the new software, a permanent split can occur. For example, Ethereum has hard-forked to "make whole" the investors in The DAO , which had been hacked by exploiting a vulnerability in its code. In this case, the fork resulted in a split creating Ethereum and Ethereum Classic chains. In the Nxt community was asked to consider a hard fork that would have led to a rollback of the blockchain records to mitigate the effects of a theft of 50 million NXT from a major cryptocurrency exchange.
The hard fork proposal was rejected, and some of the funds were recovered after negotiations and ransom payment. Alternatively, to prevent a permanent split, a majority of nodes using the new software may return to the old rules, as was the case of bitcoin split on 12 March See also: Distributed ledger.
