Many decentralised applications dapps are in their beginning phases in terms of technology and regulation, which for some means the future of blockchain has an uncertain look. Some investors question whether or not these dapps will be useful, and struggle as the business models have yet to be proven. Few companies have undergone a large-scale transformation to blockchain, and non-blockchain firms are nervous to invest a large amount of resources to blockchain. This attitude, however, is changing quickly. The State of Blockchain report by Coindesk shows that more traditional companies are opening up to blockchain, realising its potential to solve business challenges. Furthermore, many firms noted blockchain technology could bring new opportunities to their company, democratising trust and promoting great inclusion of the masses.

Ethereum hits a one-month high and is up nearly 50% in the last two weeks
In the past 18 months since the beginning of , enterprise blockchain adoption has been progressing steadily. Companies and governments alike are all trying to use this technology to solve some of the most difficult problems in the world of transactions. Businesses and regulations have strong requirements on identities and permissioning, which tend to lead them towards a permissioned over a permissionless a. For these permissioned chains, three blockchain protocols have emerged as the top choices: Hyperledger Fabric , Enterprise Ethereum and R3 Corda.
Both Fabric and Enterprise Ethereum are general purpose tools for any industry, while Corda is custom-designed for the financial industry. Each protocol option has a very different lineage and design focus, and all three have seen major adoptions by serious businesses and governments running on production-quality systems today. In full disclosure, I have personally worked on two of them: as a Fabric committer responsible for the development of node.
This blog attempts to compare these top three widely applicable protocol options without making judgement on which one is better. At a high level, the differences between Ethereum vs Fabric vs Corda can be summarized as follows:. Understanding how Enterprise Ethereum clients, Hyperledger Fabric and R3 Corda protocols came about is not an academic exercise; it will help explain some of the major design and functional differences between them. This approach fosters interop, while allowing multiple innovators to work independently on solutions to Enterprise requirements.
There are four major Enterprise Ethereum implementations active in the enterprise scene. Three of them are modified from a public Ethereum client, with a fourth developed from scratch.
This lineage allows the Enterprise Ethereum clients to inherit the relevant skills and knowledge base in the large Ethereum developers community for developing enterprise solutions. At the same time, almost all of the built-in features designed to guard the client from the most cunning hackers in the public blockchain network are also inherited wholesale.
This is mostly a positive, because enterprises always welcome battle-tested design and implementation. Besides tracing their lineage back to the public ethereum blockchain, the ongoing development of the enterprise ethereum implementations are also heavily influenced by the EEA standard body. With member organizations spanning a wide range of industries, technology companies and startups, the standard body is well positioned to link protocol designs to real customer requirements. With the first line of code written in the summer of , Hyperledger Fabric was designed with enterprise usage in mind.
The Linux Foundation launched the Hyperledger charter in December and IBM contributed its open blockchain code base to give birth to Hyperledger Fabric shortly after. Fabric enjoys wide open source participation from technology companies, consulting firms and startups in multiple countries. Developers and researchers from IBM are still the leading sources of code contribution, design and architecture.
The Hyperledger community is an umbrella organization that includes other code bases such as Sawtooth driven by Intel, Iroha by Soramitsu, Indy by Evernym, and two Ethereum implementations, Burrow by Monax and Besu by PegaSys a team in ConsenSys , plus a number of tools projects for various other concerns such as cross-chain interoperability, ops, development toolchain and crypto modules. This also means that getting started is significantly more involved compared to Enterprise Ethereum.
Corda started first as a closed-source project within R3, which is a consortium invested by financial companies, dedicated to developing DLT Decentralized Ledger Technology for the financial industry. It was later open sourced in github. Committership are held by R3 employees only. Corda architecture design is heavily influenced by requirements from the financial industry, mainly privacy and regulation compliance.
Key aspects include using a UTXO Unspent Transaction Output transaction model, and all transactions involving only the counterparties making them inherently private though the validating notary service nodes can still see the full transaction details. All blockchain systems need a consensus mechanism to ensure all nodes have the same view of the transactions input and order. First all nodes agree on the transactions order inside a block, then the transactions are independently executed by each node to calculate the resulting state.
Ethereum is built on such a consensus model. These two seemingly opposing goals are achieved by removing non-deterministic language features such as file systems, network IO, clocks, floating point arithmetic etc.
The result is a new domain specific language called Solidity. Fabric took a completely different approach by tolerating , instead of eliminating, non-determinism in its consensus model. Offering full languages for smart contracts is a design principle Fabric holds true since the beginning. As of this writing, Fabric Chaincodes can be written in three full language runtimes: Golang, Node.
Giving chaincode developers the full power of the programming language inevitably introduces risks of non-determinism from bad coding. Fabric adopted the unique execute-order-validate consensus design, so that the blockchain system can endure bad transactions caused by non-deterministic Chaincode while developers continue to perfect the logic and implementation. Details of the design is beyond the scope of this particular blog.
You can refer to the comprehensive documentation on the Hyperledger Fabric docs site for the full details. Corda consensus design is very similar to Fabric. First the nodes involved in the transaction coordinate among them to process the transaction by executing the target contract and signing the execution result.
Once the required signatures are collected, the initiator node is responsible for sending the transaction to the notary service for consensus signature. The notary service maintains a full history of all the transactions that have been submitted and is able to determine if a double spending situation is happening.
Once the notary service approves the transaction and signs of on the proposed result, the transaction is finalized and committed by all the parties. This makes it effectively the same execute-order-validate design that Fabric follows. Fabric employs a multiversion concurrency control MVCC technique borrowed from database design.
Under the cover, the chaincode engine keeps track of what state values are being viewed in readset and updated in writeset when the smart contract is executed. This is more than a subtlety. The implication is that if a series of transactions need to modify the same state value, they must be regulated such that no more than one transaction lands inside a single block.
Otherwise the application will observe a lot of invalid transactions due to concurrent modifications. In the Fabric community, we have seen a rather significant cognitive barrier around this point among the application developers. Techniques exist to program around this limitation, such as utilizing the composite key capability to assemble unique keys for each transaction while having the ability to group together keys targeting the same underlying state variable.
The high-throughput sample application demonstrates how this can be done. Note, though, that not all scenarios can take advantage of this technique. Even though Corda is built on the same "execute first and order next" design principle, its UTXO based model intrinsically guarantees that each input is unique.
If any two transactions attempt to use the same input, a double spending situation is detected and the later transaction will be rejected, because the input will have already been consumed by the earlier transaction.
The smart contracts maintain a world state that is scoped to that smart contract and each transaction can update or query the latest values. There are important distinctions in the state management between Ethereum and Fabric, though. Each Ethereum smart contract is given an account by the network after deployment and can hold balances in Ether or tokens. A chaincode can also call another chaincode, but the transaction identity is always kept constant as the transaction signer who submitted the transaction throughout the calling chain.
On a Fabric network, setting up an escrow account therefore involves adding an external party. As a result, the external account responsible for the escrow must prove its neutrality to the rest of the participants.
Corda transactions work very differently. First of all, they are based on UTXO instead of account state model. This in theory should make it more friendly to concurrent processing, because each transaction is supposed to use unique inputs. This should work as expected with fungible assets cash, bond, etc. But for non-fungible assets, which can not be split, any updates can only be performed one transaction at a time. If more than one transaction attempt to modify the same non-fungible asset, then it constitutes double spend and the later transaction, as ordered by the notary service, will be rejected.
In addition, almost all Corda transactions are about collecting multiple signatures in order to fully authorize the state transfer. Multi-party signing authorization scheme with Ethereum or Fabric would require either the applications doing the coordination to collect signatures, or submitting multiple transactions each from a different signatory. Corda transactions on the other hand is natively built on the concept of signature collection and coordination, using "flows". Both Enterprise Ethereum , such as Quorum and Besu, and Fabric support privacy with private transactions, where transactions are sent only to a subset of nodes and kept hidden from the rest.
They are both built on a similar design, by using direct peer-to-peer communication to distribute private payloads and using a hash to record the proof of the transaction in the public ledger. Details of the design can be seen at Quorum github and Fabric documentation. Quorum and Besu always encrypts the private payload at the node receiving the private transaction from the client application, before sending it to other nodes designated to participate in the transaction. If encrypted, then the client application is responsible for distributing the decryption key to the endorsing peers.
The hash also represents different content. In Quorum and Besu , because execution is done later, the hash can only represent the encrypted input. This means if the nodes do not agree on the resulting private state after execution, there is no way to discover that. In Fabric on the other hand, the private state is calculated during the endorsement phase by the peers execution the private transaction, and the resulting private state is represented by the hash, along with the input.
As a result, the consistent hash on all the nodes after consensus guarantees that the participating nodes of the private transactions always agree on private states. Fabric channels can be thought of as separate blockchains, because each channel maintains its completely separate instance of a ledger, shared among the participating nodes of that channel.
Before the introduction of the private data collection in release 1. Corda is entirely built on the philosophy that all transactions are "private". In other words transactions are only sent to the specific counter-parties involved in the specific real-world scenario.
On the other hand, there must be a neutral 3rd party that can act as witness that the transaction has happened correctly, especially in terms of order relative to each other and free of double-spend. That is the role of the notary service. In order for the notary service to perform its function, they must maintain the entire history of the transactions around the asset in question and have visibility to the content of each transaction under the scrutiny. The notary service described above is called validating notary.
It is essentially a counter-party in all transactions, with full visibility to the transaction details. Corda also supports non-validating notaries for privacy purposes. Non-validating notaries only checks for double-spending without validating the transaction input themselves.
Transaction details such as signer identities are hidden from non-validating notaries. This provides similar privacy support as the design adopted by Quorum as well as Hyperledger Besu which supports the same private transaction design and Fabric, where only the hash for the private transaction is shared with the consensus service.
This is by design because in the public blockchain it would not be a good idea to allow the logic behind a contract to be changed after public investment with ICOs. Ethereum also allows anybody to deploy smart contracts. Ethereum contract code can be re-used.

Gaurav S. Well, both were major exchanges. And both downgraded their status from Premium to General members. It was an attempt to find more use-cases for blockchain technology, then fund the creation of those use-cases faster than the EEA. However, that plan seems to be falling apart, which is bad for Hyperledger and good for the EEA. A Fortune working on its behalf.
Ethereum Price Forecast: ETH May Profit from Rival’s Failing Business
Blockchains like Ethereum require multiple servers to execute processor intensive tasks which can create scalability issues. The new specification enables these demanding tasks to be offloaded in a trusted manner. It also includes several privacy-enhancing features. The latter enables private encrypted data to be used from multiple parties, and to calculate a result without the source data ever being revealed. One of the participants, iExec, has provided a more detailed blog post. And the specification can be download from EEA website. The EEA outlined four needs the specification aims to address: Private transactions on a blockchain between mutually-untrusting parties without disclosing transaction details to other parties who also have access to the blockchain Disclosure of partial information to chosen parties on a blockchain, while maintaining the confidentiality of other information from those same chosen parties Offloading selected transactions from the main blockchain to a trusted compute environment to improve performance Attested oracles to provide trusted external information needed for some enterprise use cases. An oracle is a way to use date from an API on a blockchain. You may also like.
The Enterprise Ethereum Alliance Just Got A Whole Lot Stronger
Its global community includes a mix of multinational giants as well as start-ups. Through the alliance, members have created a forum where they can share knowledge and foster the widespread adoption of Ethereum among institutional players. Just some of the potential use cases touted by the EEA include blockchains being used to promote food safety. This technology can be used at every stage along a supply chain, delivering greater transparency to consumers. In the event that products need to be recalled, advocates argue that this can speed up the process — and ensure that the source of a problem can be identified far faster than at present.

Key Use Cases for Ethereum and Blockchain
These specifications are intended to ensure developers are on the same page and creating interoperable programs that collectively turn Ethereum into a considerably more complete and useful platform. It's essentially the dress code for the Ethereum party, which would make EEA developers dress coders. Right now, cryptocurrency is going through a bit of a platform war, where protocol-level systems like Ethereum, its competitors and its non-competitors are all trying to win the hearts and minds of developers and users around the world. The goal is to create a platform which can become widely used and a standard in its own right. And this means establishing standards within that platform to foster its growth and to ensure those potential users are able to more consistently tap into the system to experience reliable applications.

Blockchain spending has been increasing dramatically over the last few years and it looks like the number two crypto by market capitalisation is leading the way in terms of corporate adoption. For many Ether investors, enterprise adoption is all important. In , Enterprise Ethereum Alliance announcements were often accompanied by massive price surges for the number two crypto by market capitalisation. Meanwhile, investors waited for one of these massive companies to develop a killer application for the blockchain that requires the use of vast quantities of Ether, thus sending the price rocketing. Things have not exactly turned out as many had expected. The Enterprise Ethereum Alliance EEA has not been in the news much of late and there is no corporate use case of the blockchain that has sent the price parabolic again.
The Enterprise Ethereum Alliance is a vast network of businesses, organizations, and even national governments who all support Ethereum; both as a unit of exchange and as technology. The Enterprise Ethereum Alliance, or EEA, currently has over members, which makes it the largest open-source blockchain alliance in the world. The addition of Mastercard may be a surprise to some people due to the fact that many view Ethereum as a direct competitor to credit cards.
